Abstract: Soldiers operating in the desert wearing body armor and other heavy clothing cannot adequately dissipate heat Both physical and mental fiincflons are impaired when body core temperature increases. Performance can be enhanced and health risks reduced with the aid of the body core cooling device being developed in this program. The development described here builds on successful demonstrations by Heller et al. at Stanford University, which showed that heat can be extracted from the body core through the palm of the hand - up to 65 W for individuals with vasodilation and mild hypertherinia. In the present DARPA-sponsored research program, Physical Sciences Inc. (PSI) began the engineering of a practical hand cooling device that could be deployed in combat vehicles. The report describes an engineering thermal analysis of the hand, calorimetry experiments, and the design and testing of a thermoelectric hand cooling device representative of a device that might be deployed.
