Abstract
A cooling and warming device includes a housing having a receiving space formed therein. The receiving space has a lower end mounted with a heat exchanger having a heating element therein, so that a cooling unit can be placed into the receiving space from an upper end of the receiving space to make the cooling unit contact with an upper surface of the heat exchanger. The housing further includes a liquid tank used to store a predetermined volume of a liquid, and a control circuit used to control the heating element or a pump for guiding the liquid in the liquid tank between the heat exchanger and a blanket, so as to form a heat exchange circulating pathway therebetween. Thus, a uniform heat exchange for cooling or warming the liquid in the liquid tank will be carried out by the cooling unit or the heating element through the heat exchanger.
Description
- The present invention relates to a cooling and warming device, and more particularly to a cooling and warming device comprising a receiving space, a cooling unit in the receiving space, and a heat exchanger on the bottom of the receiving space for executing a heat exchange to cool a liquid in the cooling and warming device without any fan and compressor.
- A traditional active high-speed cooling and warming device is disclosed in Taiwan Utility Mode Pat. No. M268546, as shown in
FIG. 1 , wherein the cooling and warming device comprises ahousing 10. Thehousing 10 includes acontrol circuit 11, aliquid tank 12, aheat exchanger 14, aheat sink 16, afan 18, and acompressor 19, wherein theliquid tank 12 is provided with apump 120 therein. Theheat exchanger 14 is provided with a liquid guiding channel (not shown) wound therein and a heat pipe (not shown) inserted into a central portion thereof. Furthermore, thehousing 10 further includes arefrigerant pipe 15 wound between theheat exchanger 14 and theheat sink 16. Therefrigerant pipe 15 has two ends connected to thecompressor 19, respectively. Theliquid tank 12 is used to store a predetermined volume of a liquid (such as water). Thecontrol circuit 11 is used to control thepump 120, theheat exchanger 14, thefan 18, and thecompressor 19. Thepump 120 guides the liquid in theliquid tank 12 to theheat exchanger 14 and a cooling and warming blanket (not shown) in turn. Then, the liquid is guided back to theliquid tank 12 through the cooling and warming blanket, so as to form a heat exchange circulating pathway. - As described above, when the liquid in the
liquid tank 12 is passed through theheat exchanger 14, a low-temperature refrigerant in therefrigerant pipe 15 can absorb heat of the liquid in the liquid guiding channel, so as to carry out the heat exchange for cooling the liquid. Then, the heat absorbed by the refrigerant in therefrigerant pipe 15 is firstly transferred to theheat sink 16, and then the heat on theheat sink 16 is dissipated by airflow inputted by thefan 18. Furthermore, thecompressor 19 compresses the refrigerant, so as to restore the refrigerant in a low-temperature condition. Alternatively, when the liquid in theliquid tank 12 is passed through theheat exchanger 14, there is a heat exchange between the liquid and the heat pipe, so that the liquid guided into the cooling and warming blanket will be maintained in a desired cooling/warming temperature. - However, because the cooling and warming blanket is generally an article placed on a bed for use, the cooling and warming device must be mounted on a position adjacent to the bed. Thus, when the cooling and warming device starts to carry out a heat exchange for cooling, the
fan 18 and thecompressor 19 in the cooling and warming device will operate. At this time, it seems to place a miniature air conditioner adjacent to the bed. Especially, the noise caused by the operation of thefan 18 and thecompressor 19 will buzz and bother a user's ear, resulting in affecting the sleep quality of the user. Even, it may cause the problem of sleep disorder. As a result, it is important to think how to solve the noise problem caused by the operation of thefan 18 and thecompressor 19 under maintaining the original function of the cooling and warming device. - It is therefore tried by the inventor to develop a cooling and warming device to solve the noise problem caused by the fan and the compressor under maintaining the original heat exchange function of the cooling and warming device.
- A primary object of the present invention is to provide a cooling and warming device, which comprises a housing including a receiving space formed therein, wherein the receiving space has a lower end wherearound a heat exchanger which is provided with a heating element therein is fixedly mounted, so that a user can place a cooling unit into the receiving space from an upper end of the receiving space to make the cooling unit contact with an upper surface of the heat exchanger. The housing further includes a liquid tank, a pump, and a control circuit, wherein the liquid tank is used to store a predetermined volume of a liquid, and the control circuit is used to control the pump and the heating element. The pump guides the liquid in the liquid tank to the heat exchanger and a cooling and warming blanket in turn. Then, the liquid is guided back to the liquid tank through the cooling and warming blanket, so as to form a heat exchange circulating pathway. Thus, a uniform heat exchange for cooling the liquid in the liquid tank will be carried out by the cooling unit through the heat exchanger. Alternatively, the control circuit controls the heating element, so that a uniform heat exchange for warming the liquid in the liquid tank will be carried out by the heating element through the heat exchanger. As a result, the liquid guided into the cooling and warming blanket will be maintained in a desired cooling/warming temperature, so that a heat exchange circulation can be carried out in a green energy-saving manner without any fan and compressor.
- The structure and the technical means adopted by the present invention to achieve the above and other objects can be best understood by referring to the following detailed description of the preferred embodiments and the accompanying drawings, wherein
-
FIG. 1 is a schematic view of a traditional cooling and warming device; -
FIG. 2 is a schematic view of a cooling and warming device according to a preferred embodiment of the present invention; -
FIG. 3 is an exploded perspective view of a heat exchanger according to the preferred embodiment of the present invention; and -
FIG. 4 is a schematic view of a receiving space of the cooling and warming device according to the preferred embodiment of the present invention, wherein the receiving space only receives water. - Referring now to
FIG. 2 , a cooling and warming device according to a preferred embodiment of the present invention is illustrated. As shown, the cooling and warming device comprises ahousing 2 including areceiving space 3 formed therein. Thereceiving space 3 has an upper end formed with anupper opening 30 exposed out of a surface of thehousing 2, and a lower end formed with alower opening 32, wherearound aheat exchanger 4 is fixedly mounted. Thus, a cooling unit 5 (such as water, ice, a refrigerant, or a bottle of frozen liquid) can be placed into thereceiving space 3 from theupper opening 30 to make the cooling unit 5 contact with an upper surface of theheat exchanger 4. Theheat exchanger 4 is provided with aheating element 40 therein. Aliquid tank 6 is mounted in thehousing 2 for storing a predetermined volume of a liquid. Apump 7 is mounted in thehousing 2 and sandwiched between theliquid tank 6 and theheat exchanger 4. Acontrol circuit 8 is mounted in thehousing 2, and electrically connected to thepump 7 and theheating element 40 for controlling thepump 7, so that the liquid in theliquid tank 6 will be firstly guided to theheat exchanger 4, and then transferred to a cooling and warmingblanket 9. Finally, the liquid is guided back to theliquid tank 6 through the cooling andwarming blanket 9, so as to form a heat exchange circulating pathway. Thus, a uniform heat exchange for cooling the liquid in theliquid tank 6 will be carried out by heat with the cooling unit 5 through theheat exchanger 4. Alternatively, thecontrol circuit 8 controls theheating element 40, so that the liquid in theliquid tank 6 can be warmed through theheat exchanger 4, and the liquid guided into the cooling and warmingblanket 9 will be maintained in a desired cooling/warming temperature. As a result, a heat exchange circulation can be carried out in a green energy-saving manner without any fan and compressor. - Referring back to
FIG. 2 , in the preferred embodiment of the present invention, theheat exchanger 4 comprises a metalupper plate 42, a liquid guidingunit 44, and a metallower plate 46. An upper surface of the metalupper plate 42 is facing thelower opening 32, while theliquid guiding unit 44 is mounted on a lower surface of the metalupper plate 42. The liquid guidingunit 44 has an upper surface and a lower surface wound with a liquid guidingchannel 440, as shown inFIG. 3 . An upper surface of the metallower plate 46 is mounted on the lower surface of theliquid guiding unit 44, and theheating element 40 is mounted in the metallower plate 46. Meanwhile, a lower surface of the metallower plate 46 is provided with aliquid inlet 460 and aliquid outlet 462, each of which is penetrated through the metallower plate 46, respectively. As a result, when thecontrol circuit 8 starts thepump 7, thepump 7 guides the liquid in theliquid tank 6 to theliquid guiding unit 44 through theliquid inlet 460, and then the liquid is guided to the cooling andwarming blanket 9 through theliquid outlet 462. Finally, the liquid is guided back to theliquid tank 6 through the cooling andwarming blanket 9, so as to form a heat exchange circulating pathway. Thus, a uniform heat exchange for cooling the liquid will be carried out by the cooling unit 5 on the upper surface of the metalupper plate 42 through the metalupper plate 42 and the metallower plate 46. Alternatively, a uniform heat exchange for warming the liquid can be carried out by theheating element 40 in the metallower plate 46. - Referring now to
FIG. 3 , in the preferred embodiment of the present invention, a (lower) surface of the metallower plate 46 is provided with anoverheat protection unit 48 corresponding to theheating element 40. Theoverheat protection unit 48 is electrically connected to thecontrol circuit 8 for detecting the temperature of the metallower plate 46. When theheating element 40 is in a normal operation status, theoverheat protection unit 48 allows an electric current of thecontrol circuit 8 to pass through theheating element 40, so that theheating element 40 can continue to heat the liquid. However, when theheating element 40 is in an abnormal operation status that causes the metallower plate 46 to be overheated, theoverheat protection unit 48 will be actuated, so that thecontrol circuit 8 will stop supplying the electric current to theheating element 40, in order to prevent the cooling and warming device from being overheated and burned. Preferably, theoverheat protection unit 48 can be a thermal fuse, while theheating element 40 can be a heat pipe. - In the preferred embodiment of the present invention, the surface of the
housing 2 is provided with a control panel (not shown). The control panel is electrically connected to thecontrol circuit 8, and used to respectively start/control thepump 7 or theheating element 40 by inputting control signals to thecontrol circuit 8. Furthermore, referring toFIG. 2 again, thelower opening 32 of the receivingspace 3 has a diameter greater than that of theupper opening 30. Meanwhile the receivingspace 3 is tapered from thelower opening 32 to theupper opening 30 until a portion of the receivingspace 3 has a diameter equal to that of theupper opening 30. Thus, a relatively lower portion of the receivingspace 3 has a volume (or inner space) greater than that of other portion thereof. As a result, when a user places the cooling unit 5 (such as ice, refrigerant, or a bottle of frozen liquid) into the receivingspace 3 from theupper opening 30, the user still can further place a few of another liquid (such as cooled water or iced water) thereinto, so that the low temperature of the cooling unit 5 can be uniformly distributed on the upper surface of theheat exchanger 4 through the another liquid. The structural design that the relatively lower portion of the receivingspace 3 has a volume (or inner space) greater than that of the other portion thereof can also prevent a few of the another liquid placed in the receivingspace 3 from overflowing out of the receivingspace 3 due to shake or vibration during transporting the receivingspace 3. - As described above, the cooling and warming device provides several advantages as the following:
- 1. The cooling and warming device cools the liquid by an additional cooling unit 5 without using the refrigerant, so that the cooling and warming device needs not to provide any compressor, refrigerant pipe, heat sink, fan, and other related elements. Thus, the volume and the weight of the cooling and warming device is smaller than those of the traditional cooling and warming device, while the structure and the installation procedure of the cooling and warming device is substantially simplified. As a result, the installation time and the manufacture cost of the cooling and warming device will be efficiently lowered;
- 2. Because the cooling and warming device has no any compressor and fan, there will be no noise caused by the compressor and fan and no heat wind caused by the fan in the cooling and warming device;
- 3. There is no any heat dissipation problem caused by the refrigerant pipe and the heat sink in the cooling and warming device;
- 4. The cooling unit 5 can be selected from ice or a bottle of frozen liquid, all of which are easily available in daily life. Furthermore, only one 1500 c.c. bottle of frozen liquid can carry out the heat exchange circulation of the cooling and warming device for cooling the liquid in the cooling and
warming blanket 9 and maintaining the desired cooling/warming temperature (between 22° C. and 26° C.) of the liquid therein about more than 5 hours. As a result, the cooling and warming device can provide the heat exchange circulation for cooling the cooling andwarming blanket 9 in a green energy-saving manner without any fan and compressor; and - 5. When an air conditioner in a room is started to cause a heat exchange for cooling the air in the room, the receiving
space 3 of the cooling and warming device in the room can only receive water as the cooling unit 5, as shown inFIG. 4 . At this time, a heat exchange for cooling the water in the receivingspace 3 will be carried out by the cooled air in the room, so as to cause a heat exchange circulation of the cooling and warming device for cooling the liquid in the cooling andwarming blanket 9. Generally, flowing water has the temperature slightly lower by about 1° C.-2° C. than the ambient temperature. Thus, if it is desired to maintain the temperature of the liquid in the cooling andwarming blanket 9 in a predetermined range between 26° C. and 27° C., the target temperature of the air conditioner needs not to be set to a temperature value lower than 26° C. Instead, the target temperature only needs to be adjusted about 2° C. up to a higher temperature value, such as 28° C.-29° C. At this manner, the cooling andwarming blanket 9 still can be maintained in a cooled status, instead of a hot status, so as to carry out the energy-saving effect. - The present invention has been described with a preferred embodiment thereof and it is understood that many changes and modifications to the described embodiment can be carried out without departing from the scope and the spirit of the invention that is intended to be limited only by the appended claims.
