Boiling and cooling device

A boiling and cooling device comprising:

• a refrigerant tank for storing a liquid-phase refrigerant, on the outer surface of which a heating body is attached;
• and a radiating section for cooling and condensing the refrigerant, which is boiled by heat of the heating body, and for returning the condensed refrigerant to the refrigerant tank, wherein the refrigerant tank and the radiating section are joined to each other by means of brazing,
• a container composing the refrigerant tank including:
• a base plate made of copper, one face of which is exposed inside the refrigerant tank;
• a block made of copper, one face of which is contacted with the base plate, the other face of which is contacted with the heating body;
• and a frame for reinforcement arranged in a portion of the base plate with which the block is not contacted, wherein
• the frame is made of material, the rigidity of which, after the completion of the brazing process, is higher than the rigidity of copper.
