ABSTRACT:
A cooling device, particularly for heat protective suits, comprises, a housing having a bottom with a heat exchanger surface exposed therein, and a solid refrigerant, such as dry ice, overlying the heat exchanger surface. The ice is preferably biased toward the heat exchanger surface and a flexible intermediate layer is disposed between the dry ice and the heat exchanger surface. The flexible intermediate layer is saturated with a fluid, such as one which remains liquid to below the sublimation point of the solid refrigerant. The heat exchanger surface is advantageously connected through connecting lines and a pump to circulate it through various passages in the protective vest or suit.
