Abstract:
There is provided a cooling device including: a heat receiver ( 4 ) that transfers heat from a heat generation body to a refrigerant, a heat radiator that is connected to the heat receiver ( 4 ) via a heat radiation path ( 6 ), and a return path ( 7 ) that connects the heat radiator and the heat receiver ( 4 ) with each other, in which the refrigerant circulates in order of the heat receiver ( 4 ), the heat radiation path ( 6 ), the heat radiator, and the return path ( 7 ) while causing a gas-liquid two-phase change and cools the heat generation body, and in which the heat receiver ( 4 ) includes a heat receiving plate ( 11 ) which is in contact with the heat generation body and absorbs the heat, and a heat receiving cover ( 14 ) which covers a surface of the heat receiving plate ( 11 ) and forms a heat receiving space ( 13 ). A check valve ( 18 ) that opens in a case where pressure of the return path ( 7 ) is larger than pressure in the heat receiving space ( 13 ) is provided between the return path ( 7 ) and the heat receiver ( 4 ) and a hydrophilic surface treatment film ( 22 ) is formed on a recessed portion ( 24 ) of a surface of the heat receiving plate ( 11 ).

Claim (Index 2):
The cooling device according to  claim 1 ,\n wherein, in the heat receiving space, the heat receiver includes\n a refrigerant inflow portion from which the refrigerant flows into the heat receiving space, the refrigerant inflow portion being near a center of the heat receiving plate, and \n radial grooves which are radially provided from the refrigerant inflow portion, and \n wherein the recessed portion is provided in a bottom surface of a corresponding one of the radial grooves.
