Abstract:
1. In combination with a heat generating exterior portion of the body of an individual, said exterior portion having an arcuate contour, improvements for removing heat from said exterior portion, said improvements comprising a cooled heat transfer device to draw heat away from and cool the exterior portion of the body, the improvements including (a) a pliable water impermeable outer wall (b) a plurality of spaced apart hollow fluid tight modules ( (c) a first heat-exchange composition in said inner space contacting said outer surface area of each of said fluid tight modules and comprising a first liquid which undergoes a change of state from the liquid phase to the solid phase at a selected temperature of transformation less than fifteen degrees F., said selected temperature of transformation being lower than the coldest temperatures found in conventional household freezers; (d) a second heat-exchange composition in said inner space of each of said modules and comprising a frozen second liquid which undergoes a change of state from a liquid phase to a frozen solid phase at a temperature in the range of fifteen degrees to thirty-two degrees F., said second fluid having a freezing point that is higher than the freezing point of said first fluid, said heat transfer device having (e) convection currents in said first fluid moving upwardly away from the exterior portion of the individual's body as the result of heat absorbed by said first liquid; and, (f) a plurality of channels each
