Abstract

PURPOSE:To obtain a cooling effect with a simple construction by providing a natural convection cooling circuit which introduces a refrigerant gas from a housing cooling chamber, condenses it by cooling with a heat exchanger, then returns it into a refrigerant liquid of the housing cooling chamber. CONSTITUTION:A refrigerant gas 24 accumlated at the upper section of a cooling chamber 30 is connected to a heat exchanger 22 thrrough an extracting pipe 19 and a pipe line 21, and it is cooled by the heat exchanger 22, and when liquefied, the refrigerant flows into a return pipe 20 through a pipe line 23 by its own weight. During this time, the refrigerant is liquefied by the heat exchanger 22, therefore, the pressure of the refrigerant is lowered to a saturation pressure at the temperature of the heat exchanger 22, and the refrigerant gas flows in through the extracting pipe 19 and the pipe line 21. Thereby, the heat can be absorbed in the cooling chamber and discharged in the heat exchanger 22 by means of natural circulation of the refrigerant. Moreover, the cooling chamber 30 is built in a double-bottomed structure at the bottom section of the housing 4, and a cooling effect can be obtained with the simplest construction.
