Problems to be Solved by the Invention With the above-mentioned immersion liquid cooling, for example, when a large circuit board is completely cooled, the cooling ability of the semiconductor elements disposed above is reduced due to the influence of air bubbles generated from the semiconductor elements below. If all of the heat is radiated from the condenser above the TYC liquid-cooled container, impurity gas such as air will enter the liquid-cooled container from the outside, reducing the cooling capacity. The present invention is intended to solve this difficult problem.0Means for solving the problemThe above problem can be solved by the present invention. In a cooling device; The present invention is solved by a liquid cooling device characterized in that a cooling pipe is provided through which the cooling liquid passes, and a liquid having a boiling point lower than the boiling point of the cooling liquid is circulated through the cooling pipe. According to the present invention, since a low boiling point liquid is placed in the cooling liquid and circulated, air bubbles generated in the cooling liquid can be efficiently condensed and eliminated.
