A cooling system includes a pressurized liquid refrigerant source having a liquid refrigerant and a cooling garment coupled to the liquid refrigerant source. The cooling garment defines chambers containing a heat transfer fluid. During operation, a user places the cooling garment in thermal communication with a body portion of a subject. As the cooling garment receives the liquid refrigerant from the pressurized source, the liquid refrigerant thermally contacts the heat transfer fluid and evaporates, thereby reducing the temperature of the heat transfer fluid. The heat transfer fluid, in turn, reduces the temperature of the body portion in thermal communication with the cooling garment. The heat transfer fluid acts to substantially evenly distribute cooling, as provided by the evaporation of the liquid refrigerant, to the body portion contacting the cooling garment to minimize localized “cold spots” within the chamber. |
