PURPOSE:To switch heating and heat retrieving automatically without operating a valve or the like and accompanying heat loss accompanied by the switching when a temperature turns into preset range by a method wherein two pieces of thermo-siphon type heat pipes are connected through a double tube to make heat exchange surfaces for heat retrieving and heating. CONSTITUTION:Two pieces of thermo-siphon type heat pipes 1, 2 are connected through a double tube structure 3A to utilize the lower part thereof for heating and the upper part thereof for heat retrieving while the inside thereof are evacuated and operating liquid is sealed therein. Absorbing agent 3, necessary for heating and heat retrieving, is loaded around the double tube structure 3A. The lower part of the heat pipe 1 is provided with a heat exchanging vessel 6 capable of effecting heat exchange between fluid 4 for heating while the upper part of the same is provided with the heat exchanging vessel 7 capable of effecting heat exchange between the fluid 5 for heat retrieving. Respective heat pipes have structures well known as thermo-siphon type. |
