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 1):
A cooling device comprising:\n a heat receiver that transfers heat from a heat generation body to a refrigerant; a heat radiator that is connected to the heat receiver via a heat radiation path; and a return path that connects the heat radiator and the heat receiver with each other, wherein the refrigerant circulates in order of the heat receiver, the heat radiation path, the heat radiator, and the return path while causing a gas-liquid two-phase change and cools the heat generation body, wherein the heat receiver includes\n a heat receiving plate which is in contact with the heat generation body and absorbs the heat, and \n a heat receiving cover which covers a surface of the heat receiving plate and forms a heat receiving space, \n wherein a check valve that opens in a case where pressure of the return path is larger than pressure in the heat receiving space is provided between the return path and the heat receiver, and wherein a hydrophilic surface treatment film is formed on a recessed portion of a surface of the heat receiving plate.
