ABSTRACT:
A cooler for automotive use which uses neither the power of the engine nor that of the battery, but instead operates from power supplied by solar cells mounted on the roof of the vehicle. The cooler includes a liquid coolant filled evaporator, a radiator, a heat pipe connecting the evaporator and the radiator, a valve provided in series with the heat pipe for regulating the flow of coolant vapor through the heat pipe, the solar cells, a return pipe through which coolant liquefied in the heat sink is returned to the evaporator, a coolant circulating pump provided in the return pipe and operated by power generated by the solar cells, and fans provided near the evaporator and the radiator which are also operated by power generated by the solar cells. Preferably, the liquid coolant is one having a high saturated vapor pressure, boils at a temperature of about 40.degree. to 70.degree. C. at atmospheric pressure, and provides a large latent heat of evaporation.
