No. 4,738,119 disclose, respectively, cooling devices of a body comprising a garment which houses a tubing network provided with little openings or micropores through which pressurized gas flows, such as air or carbon dioxide. Said pressurized gas, once injected, expands quickly through said openings or micropores cooling itself and absorbing a great quantity of heat, producing a cooling effect to the wearer of the garment.
- Said devices present the drawback that they include at said garment a very extended and complex tubing circuit through which the cooling substance flows, resulting in a not very flexible garment. Furthermore, the tubes cool the garment only when the pressurized gas flows through them, but they cannot store frigories (negative calories) during a long time. In the other hand, any torn of said garment can affect the circuit, making the cooling device useless, and it can also promote a leak of said coolant which, depending on the kind of substance used, can involve a serious danger for the user of the device.
- Furthermore, another drawback is that said devices cannot be used with refrigerants at a very low temperature, because in these devices the coolant contacts directly the wearer of the garment.
- U.S. Pat. No. 5,787,505 discloses a device for cooling or heating a body comprising a garment with one or several pockets provided to insert a cooling or heating package. The cooling package comprises tight compartments containing water or other material which changes its state when absorbs heat, to cool therefore the wearer of said garment.
- U.S. Pat. No. 5,038,779 discloses a therapeutic garment for back pains comprising at least one pocket at the lumbar area provided to house a cooling package. The pocket is made in one piece of a material folded on the garment.
- Both devices discloses in this two documents have the drawback that they are not suitable to provide cooling at a very low temperature, because the cooling packages are in direct contact with the wearer of the garment.
- The application of the international patent WO 2005112675, of the same applicant than the present invention, discloses a device for cooling a body comprising a garment in contact with said body, liquid nitrogen as coolant to cool said garment and storing means of said coolant. The garment comprises a layer of conducting fabric with a thermal conductivity suitable to transmit by contact the heat to said coolant.
- This device has the drawback that the wearer of the garment must wear one or more deposits of liquid nitrogen, which the involved risk if there is a leak at each of said deposits. On the other hand, the use of cryogenic deposits makes the device expensive.

-
FIG. 1 is a frontal perspective view of a garment provided with the cooling system by contact, according to a first embodiment of the invention; -
FIG. 2 is a rear perspective view of the garment ofFIG. 1 ; -
FIG. 3 is a perspective view of the radiator; -
FIG. 4 is a perspective view of the radiator placed inside the container without a lid; -
FIG. 5 is a lateral section view of a helmet including the cooling system by contact, according to a second embodiment of the invention; -

FIG. 7 is a perspective view of a fridge including the cooling system by contact, according to a third embodiment of the invention; -
FIG. 8 is a plan view of the fridge ofFIG. 7 ; and -
FIG. 9 is a transversal cross-section of a wall of the fridge ofFIGS. 7 and 8 . - Hereinafter three preferred embodiments of the cooling system by contact are described.
- A first embodiment is shown if
FIGS. 1 to 4 , where it can be seen that thecooling system 1 by contact is applied to agarment 2, such as a vest. - In this case, the
cooling system 1 by contact comprises threedevices 3 for collecting and storing frigories arranged on thevest 2, and that can receive a preset quantity of cooling fluid, specifically liquid nitrogen, from an external charging device (not shown). - To do this, the
system 1 comprises means to conduct and distribute the liquid nitrogen comprising anintake duct 4 provided at an end with anintake nozzle 5 provided with a valve to be connected intermittently to the external charging device. Saidintake duct 4 is connected by its other end to a distributingelement 6 which distributes the liquid nitrogen to eachdevice 3 for collecting and storing frigories throughsecondary ducts 7. - The attachment between the
intake nozzle 5 and the external charging device can be a system of bayonet kind, because it is an efficient and comfortable attachment. Therefore, it is assured that there are no disconnection problems from the contractions produced when the liquid nitrogen flows. Thenozzle 5 can be housed inside thevest 2, and it can be uncovered by a zip, and when the charge is finished, it can be hidden inside thegarment 2. - The design of the
ducts - The material suitable for the conduction and distribution means 4 to 7 of the liquid nitrogen is a non-metallic material such as Teflon, Pyrex, Armaflex, among others, the metallic material being not suitable because it can crack.
- Another option consists in not using conducting and distributing means of the liquid nitrogen, so that each collecting and storing
device 3 of frigories is fed directly from the external charging device. Therefore, the ergonomics of thegarment 2 is enhanced. - With reference to
FIGS. 3 and 4 , each collecting and storingdevice 3 of frigories comprises acontainer 8 thermally isolated, except awall 9 with a minimum width, which will contact thegarment 2, acting as a cold transmission surface, as will be explained hereinafter. - The
container 8 can be made from a plastic material, such as polyurethane; and thecold transmission surface 9 can be made from plastic or metallic material, taking into account that the metal will provide to the garment 2 a temperature lower than about −30° C., compared with the plastic material, which will provide about −15° C. - The
container 8 comprises a body with a lid which houses inside it aradiator 10 provided with internal channels (not shown) andexternal wings 11. The material suitable for theradiator 10 is a metal, such as aluminum, copper, and steel, among others. - The charge of liquid nitrogen is injected inside 30 the
radiator 10 through anintake duct 12, and flows through internal channels, so that saidradiator 10 can collect frigories from the nitrogen when it pass through the channels, and it can increase the temperature from −198° C. (temperature of the liquid nitrogen) to about −160° C. (temperature at which the nitrogen changes its state from liquid to gas). The gas inside theradiator 10 exits outside thecontainer 8 throughexit ducts 13, providing the last frigories to thesystem 1. - On the other hand, the
container 8 comprises a viscous gel (not shown) surrounding themetallic radiator 10 and filling the volume of thecontainer 8 not filled by theradiator 10. The design of theradiator 10 is optimized thanks to theexternal wings 11 to provide a maximum 10 contact area with the gel. - Said gel has a thermal conductivity suitable for storing transferred from the
metallic radiator 10 by contact, passing from about −160° C. to about −40° C. - It must be pointed out that the gel permits to transmit cold slowly during a preset time to the
cold transmission surface 9 of thecontainer 8, which receives a temperature of about −15° C. This temperature is suitable to be supported by the human body during about two hours when it is under conditions of environmental heat of more than 100° C., as is the case of firemen. The system can provide between 20 and 40 Kilofrigories, providing a great autonomy. - The used gel can be any known gel, whose thermal properties permit to reach a suitable final temperature and to transmit cold during a preset time. Even though gel is the more suitable material because of its easy placement and adaptation to the external surface of the
metallic radiator 10, it must be pointed out that it could be used a plastic material in the place of gel, such as polypropylene, polyethylene, among others. - The
container 8 makes, therefore, the functions of containing theradiator 10 and the gel, and also of permitting the transfer of temperature through thesurface 9 presenting a thickness of 0.2 mm. - Therefore, in this first embodiment there are three layers transmitting frigories between the liquid nitrogen and the
garment 2, which are: themetallic radiator 10, the gel, and thesurface 9 which transmits 5 cold of the container. - The
system 1, once assembled, can be autoportable, i.e. it can comprise a fixation between the different components by elastic harnesses and straps. - A second embodiment is shown is
FIGS. 5 and 6 , where it can be seen that thecooling system 1 a by contact is applied to ahelmet 20, such as a motorist helmet. Thesystem 1 a is placed between anexternal layer 21 of the helmet and asurface 22 in contact with the head of the user, which will have the function of cold transmission surface, as it will be described hereinafter. - In this case, the
cooling system 1 a by contact comprises asingle device 3 a for collecting and storing frigories suitable to receive a preset quantity of cooling fluid, specifically liquid nitrogen, from an external charging device (not shown). - To do this, the
system 1 a comprises atube 23 to conduct and distribute the liquid nitrogen, in the shape of a spiral, placed inside a security paddedlayer 24, to cover efficiently the whole surface of thehelmet 20. Saidtube 23 comprises anintake nozzle 25 provided with a valve to be connected intermittently to the external charging device. The material suitable for said conduction anddistribution tube 23 of the liquid nitrogen is Teflon, and metal cannot be used for security reasons. Therefore, thetube 23 of Teflon can collect quickly a great quantity of frigories, and it can increase the temperature from −198° C. of the liquid nitrogen to about −160° C. - Adjacent to said
padding layer 24 there is alayer 26 of gel (not shown) with a thermal conductivity suitable to collect frigories transmitted by thetube 23 of Teflon through thepadding layer 24, and storing them during a preset time, passing from about −160° C. to about −40° C. - It must be pointed out that gel permits to transmit slowly the cold during a preset time to the cold transmitting
surface 22, which receives a temperature of about −15° C., being this temperature suitable to be supported by the human body during about two hours when it is under environmental heat conditions of more than 40° C., such as Formula One drivers. - Therefore, in this second embodiment there are two cold transmission layers between the liquid nitrogen and the
layer 22 of material of the helmet in contact with the head of the user, which are thetube 23 of Teflon and the gel. - A third embodiment is shown in
FIGS. 7 to 9 , where it can be seen that thecooling system 1 b by contact is applied to a fridge orcold recipient 30, that can be placed in a double bottom. - In this case, the
cooling system 1 b by contact comprises fourdevices 3 b to collect and store frigories placed each one in a wall of thefridge 30, that can received a preset quantity of cooling fluid, specifically liquid nitrogen, from an external charging device. - To do this, the
system 1 b comprises conduction and distribution means of the liquid nitrogen comprising amain duct 31 provided at an end with anintake nozzle 32 provided with a valve to be connected intermittently to the external charging device. The liquid nitrogen is distributed to each collecting and storingdevice 3 b of frigories throughsecondary ducts 33. The suitable material for the conducting and distribution means of the liquid nitrogen is a non-metallic material, such as Teflon, Pyrex, Armaflex, among others, the metal being not suitable because it can crack. - Each collecting and storing
device 3 b of frigories comprises acontainer 34 thermally isolated by an isolatingexternal layer 35, except awall 36 which will be in contact with the internal part of thefridge 30, acting as a cold transmission surface, such as will be described hereinafter. - Each
container 34 houses inside it gel (not shown) with a thermal conductivity suitable to collect frigories from the liquid nitrogen and store them during a preset time, passing from about −198° C. to about −40° C. - It must be pointed out that gel permits to transmit slowly the cold during a preset time to the
cold transmission surface 36 in contact with the internal part of thefridge 30. - Therefore, in this third embodiment there is one frigories transmission layer between the liquid nitrogen and the
cold transmission surface 36 in contact with the internal part of thefridge 30, which is the gel. - The
system 1 b can also be used in vehicles of transportation of perishable products to maintain the legal established temperature to preserve the food in harmless conditions and suitable to be consumed. - In anyone of the described embodiments control means of the transfer of temperature can be used, consisting in adjusting the distance between the contact surface with the user or object to be cooled and the cold transfer surface to modify the interchange of frigories. E.g. in the case of the garment or helmet, said control means can consist in an air chamber provided between the cold transmission surface and the human body, and said air chamber can be inflated when the final temperature is too low; or, in the case of the fridge, it can consist in other kind of means separating two metallic surfaces, one of them being the cold transmission surface.
- It must be pointed out that in some environments, the container can present a water condensation greater than that expected. When the user pretends to use the own condensation, the system can include means to store the water generated by the condensation process, using it afterwards to increase the existing frigories. To do this, said means for storing the condensing water can comprise an absorbent fabric.
- When it is not wished to use the condensation water, the system can comprise waterproofing means preventing the condensation water to contact the body or object to be cooled, and means to collect and evacuate said condensation water. E.g. in the case of a garment or helmet, it can include a tube at its lower part to evacuate the water. In the case of a fridge, it can include known systems to prevent the condensation.
- Furthermore, the system of the invention can be housed inside a thermally sealed garment to prevent condensation inside it.
