Fluid cooling pad system utilizes compressed air as a cooling source

Abstract

A fluid cooling pad system 10 utilizes compressed air as a cooling source. Compressed air 205 can provide a cooling effect for the fluid cooling pad system 10. By using a compressed air cartridge 300 to store the compressed air 205, the fluid cooling pad system is easy to maintain and the fluid cooling pad system size can be reduced. The cooling effect can also be extended by replacing an empty compressed air cartridge 300 with a filled compressed air cartridge 300. By further including a manual air pump 500 or powered air pump 600, compressed air cartridge 300 can be refilled. The fluid cooling pad system 10 is also expandable. By connecting connection tubes 107 to multiple fluid cooling pads 100, user can attach the fluid cooling pads 100 to multiple areas simultaneously, for example and without limitation, on wearable garments such as caps, helmets, and/or applied directly to the user's body.

         2 . The system of  claim 1  wherein said compressed air cartridge  300  is replaceable. 
     
     
         3 . The system of  claim 1  wherein said fluid cooling pad system  10  further includes a thermal insulated container  201  to contain said fluid container  202  to reduce heat loss between said heat transfer fluid  203  of said fluid container  202  and the surrounding environment. 
     
     
         4 . The system of  claim 1  wherein said fluid container  202  further includes one or more ice packs  204  to lower the temperature of said heat transfer fluid  203 . 
     
     
         5 . The system of  claim 1  wherein said fluid cooling pad system  10  further includes a manual air pump  500  to refill said compressed air cartridge  300 . An outlet  501  of said manual air pump  500  is connected to an inlet  209  of said compressed air connector  207 . When air is pumped, said air is ejected from said outlet  501  of said manual pump  500  and stored into said compressed air cartridge  300  via an inlet  209  of said compressed air connector  207 . 
     
     
         6 . The system of  claim 1  wherein said fluid cooling pad system  10  further includes a powered air pump  600  to refill said compressed air cartridge  300 . An outlet  601  of said powered air pump  600  is connected to an inlet  209  of said compressed air connector  207 . When air is pumped, said air is ejected from said outlet  601  of said powered air pump  600  and stored into said compressed air cartridge  300  via an inlet  209  of said compressed air connector  207 .
