ABSTRACT:
Safety equipment is disclosed comprising a three-phase heat pipe for the protection of apparatus from exceeding maximum or minimum safe working temperatures. The heat pipe has a working fluid selected so that it will not function below the desired temperature. A working fluid which has a melting point slightly above the minimum safe temperature of the equipment to be protected is preferred for protecting equipment from exceeding its minimum safe working temperature. This heat pipe may be used to cool an apparatus to a temperature where the heat pipe automatically stops functioning and keeps an apparatus from exceeding its minimum design temperature. A working fluid which has a melting point slightly below the maximum safe temperature is preferred to keep equipment from exceeding its maximum safe working temperature. This heat pipe will be inactive at normal operating temperatures but will release excess heat to cooler surroundings before safe working temperatures are exceeded. Transfer may also be by capillary action in a heat pipe having a wick.
