PURPOSE:To regulate and control a radiating side to a predetermined temperature by a method wherein an auxiliary heater is provided in the heat pipe for controlling the temperature of a satellite or the like. CONSTITUTION:Heat, generated from a heating body 1 in the satellite, is transmitted to the radiating plate by the heat pipe 4 consisting of a wick 2 and a refrigerant 3 and is radiated into the space of cosmos. The radiating side is exposed to the space of zero degree of absolute temperature, therefore, the refrigerant 3 at the radiating side is solidified. Therefore, in case it is not necessary to radiate the heat generating in the satellite, the heat pipe is not operated, however, in case it is necessary to radiate the heat, the radiating side of the heat pipe 4 is heated by the auxiliary heater 6 and thereby regulating the temperature of the radiating side so as not to be lowered below the temperature of the solidifying point thereof. The input of the auxiliary heater 6 is determined and controlled by the operation of a micro-computer or a thermal switch made by bimetal based on a condition whether the necessity of the heat radiation is existing or not or the temperature of the radiating side is lower than the melting point of the refrigerant 3 or not. |
