This cooling apparatus can improve a radiation performance by increasing the boiling area and make it difficult to cause the burnout on boiling faces by filling the boiling faces with a refrigerant necessary for the boiling. In refrigerant chambers for reserving a refrigerant, there are inserted corrugated fins for increasing the boiling area. These corrugated fins are composed of lower corrugated fins arranged to correspond to the lower sides of the boiling faces for receiving the heat of a heating body, and upper corrugated fins arranged to correspond to the upper sides of the boiling faces, and these lower and upper corrugated fins and are individually held in thermal contact with the boiling faces of the refrigerant chambers. The lower corrugated fins and the upper corrugated fins are given a common fin pitch P and are individually inserted vertically in the individual refrigerant chambers to define the individual passages further into a plurality of small passage portions. However, the lower corrugated fins and the upper corrugated fins are inserted such that their crests and valleys are staggered from each other in the transverse direction of the refrigerant chambers.

[ What is claimed is:] [1.]1. A cooling apparatus comprising:a refrigerant chamber for reserving a refrigerant to be boiled by heat of a heating body;a vapor outlet from which a vaporized refrigerant boiled in said refrigerant chamber flows out;a radiating portion having a refrigerant passage, into which the vaporized refrigerant having flown out from said vapor outlet flows, for cooling the vaporized refrigerant flowing through said refrigerant passage by the heat exchange with an external fluid;a liquid inlet into which a condensed refrigerant cooled and liquefied in said radiating portion flows;a circulating passage for circulating the condensed refrigerant from said liquid inlet to said refrigerant chamber;a connecting tank disposed between said radiating portion, and said refrigerant chamber and said circulating passage for communicating between said refrigerant passage, and said refrigerant chamber and said circulating passage;refrigerant control means disposed in said connecting tank, for controlling flow of said condensed refrigerant dropped from said radiating portion;a refrigerant tank including said refrigerant chamber and said circulating passage therein and using the upper end opening of said refrigerant chamber as said vapor outlet and the upper end opening of said circulating passage as said liquid inlet,wherein said refrigerant tank is attached at an inclination to said connecting tank; and in that the lowermost portion of said vapor outlet is positioned over the lowermost portion of said liquid inlet, andwherein said refrigerant tank is constructed such that said vapor outlet is opened obliquely upward and protruded more forward than said liquid inlet.
