BOILING AND COOLING DEVICE

摘要

Provided is a low-cost and lightweight boiling and cooling device with which entrance of a liquid refrigerant into a condensation portion is controlled. The boiling and cooling device of the present invention comprises: an accommodating portion which accommodates the liquid refrigerant; a communication chamber whose inner space communicates with an inner space of the accommodating portion; and the condensation portion which protrudes from a side of the communication chamber. The communication chamber is a plate-shaped member facing an opening of the condensation portion and disposed away from an end of the condensation portion. The communication chamber comprises an induction plate which induces the boiling liquid refrigerant to an upper part of the opening of the condensation portion, a communication hole being formed at an upper part of the induction plate. An inner fin (a heat transmission member) is disposed only at a side end in an inner space of the condensation portion.
