Description
- 1. Field of the Invention
- This invention relates to a heat absorbing device.
- 2. Description of the Prior Art
- A conventional
heat dissipating device 10 shown inFIG. 1 includes aheat semi-conductor 11 for performing hat change. Theheat semi-conductor 11 is provided with acooling surface 111 to contact with air, but if the air is too cool, moisture in the air may condense thereon to become water drops. So water can be detrimental to an electronic part, and in order to avoid contacting with air, aheat guide plate 12 is attached around theheat semi-conductor 11, having a hollow space in its interior for receiving the semi-conductor 11, with thecooling surface 111 of the semi-conductor 11 contacting with theheat guide plate 12 for heat absorbing. At the same time, theheat guide plate 12 is provided with a sealingrubber ring 121 for insulating the semi-conductor 11 from contacting exterior air, and aheat dissipater 13 is connected with theheat guide surface 112 to dissipate heat. - However, the conventional
heat dissipating device 10 has disadvantages described below although thecooling surface 12 of the semi-conductor 12 functions to insulate air. - 1. The
heat guide plate 12 has too large a dimension for wrapping around thesemi-conductor 11, so it also absorbs heat at the location not contacting the heat source, consequently cutting down the effectiveness of the semi-conductor 11. - 2. The sealing
rubber ring 121 does seal up the heat dissipater completely, so air may flow into theheat dissipater 13, and if a gap occurs between theheat dissipater 13 and the sealingrubber ring 121 because of aging or inflating, air still can flow in to let moisture accumulate inside theheat guide plate 12, potentially causing some damage to the circuit of the semi-conductor 11. - The purpose of this invention is to offer a heat absorbing device having excellent function of air insulating.
- The features of the heat absorbing device are a heat converter, a heat semi-conductor, a cool guide plate, and a moisture-proof cap. The heat semi-conductor is placed on the heat converter, and the cool guide plate is placed on the heat semi-conductor. The moisture-proof cap has an accommodating space for receiving the heat converter and the heat semi-conductor, an upper opening for fitting sealingly the cool guide plate, and a combining mouth in the bottom for the combining member of the heat converter to be fitted sealingly in. Then the two ends of the moisture-proof cap combined sealingly with the heat converter and the cool guide plate to keep the heat semi-conductor completely insulated from exterior air. In addition, the heat semi-conductor is directly and evenly connected to a heat source via the cool guide plate, it is boosted up in its efficacy.
- This invention will be better understood by referring to the accompanying drawings, wherein
-
FIG. 1 is a cross-sectional view of a conventional heat absorbing device; -
FIG. 2 is a perspective view of a heat absorbing device in the present invention; -
FIG. 3 is an exploded perspective view of the heat absorbing device in the present invention; and -
FIG. 4 is a cross-sectional view of the heat absorbing device in the present invention. - A heat absorbing device in the present invention, as shown in
FIGS. 2 and 3 , includes aheat converter 20, aheat semi-conductor 30, acool guide plate 40, ananti-moisture cap 50, afirst sealing element 60 and asecond sealing element 70. - The
heat converter 20 is composed of a nearly squaremain body 21, and themain body 21 consists of aheat absorbing member 22 in an upper portion, and a linkingmember 23 around its bottom, with a linkinghole 24 bored respectively at its four corners for receiving abolt 25 therein. - The
heat semi-conductor 30 has acooling surface 31 and aheat dissipating surface 32 oppositely. - The
cool guide plate 40 is made of a heat evenly transmitting material, having astepped projection 41 around its circumference - The moisture-
proof cap 50 is made of a material transmitting not so much heat, having a recessedaccommodating space 51, anupper opening 52, a linkingmouth 53 formed in the bottom, anannular edge 54 formed in the linkingmouth 53, and a threadedhole 55 formed respectively at four corners of the bottom. - The
first sealing element 60 is annular, made of a material having sealing function. - In order to further understand the structural features, operational technique and expected effect, how to use the invention is to be described below.
- As shown in
FIG. 4 , theheat absorbing surface 22 of theheat converter 20 contacts the heatdissipating surface 32 of the semi-conductor 30, and thecooling surface 31 of theheat semi-conductor 30 contacts thecool guide plate 40. Then the moisture-proof cap 50 is covered on theheat converter 20, with thefirst sealing element 60, thecool guide plate 30 and theheat converter 20 orderly placed in theaccommodating space 51. Then thecool guide plate 40 is just fitted in theupper opening 52, and thefirst element 60 resting around thestepped projection 41 of thecool guide plate 40 fits tightly around theupper opening 52, enabling thestepped projection 41 to tightly contact the moisture-proof cap 50. Meanwhile, the linkingmember 23 of theheat converter 20 overlaps theannular edge 54 of the moisture-proof cap 50, and thesecond sealing element 70 is coated between the linkingmember 23 and theannular edge 54. Thesecond sealing element 70 is a kind of sealing glue or a material having high sealing function. At the same time, the threadedholes 55 of the moisture-proof cap 50 overlap with the linkingholes 24 for thebolts 25 to fasten them tightly. Thus themoisture cap 50, thecool guide plate 40 and theheat converter 20 are all sealed airtight, preventing the semi-conductor 30 from contacting exterior air at all. - In using, the
heat semi-conductor 30 conducts heat, heating up theheat dissipating surface 32 but cutting down the temperature of the cooling surface, with theheat absorbing surface 22 of theheat converter 20 takes off the heat energy produced by theheat dissipating surface 32. Therefore, thecooling plate 40 performs lowering temperature owing to thecooling surface 31, as thecooling surface 31 contacts thecool guide plate 40. Moreover, thecool guide plate 40 is connected to a heat source (not shown), it dissipates heat produced thereby, with thecool guide plate 40 mixes temperature of the heat source with that of thecooling surface 31, with the moisture-proof cap 50 performing insulation, permitting thecooling surface 31 to work with the heat source for stepping up the function of the heat absorbing device in the invention. - While the preferred embodiment of the invention have been described above, it will be recognized and understood that various modifications may be made therein and the appended claims are intended to cover all such modifications that may fall within the spirit and scope of the invention.
