Document Type and Number:
WIPO Patent Application WO/2018/043442
Kind Code:
A1
Abstract:
A cooling device: that comprises a heat receiving unit (4) that transfers heat from a heat-generating element to refrigerant, a heat dissipating unit that is connected to the heat receiving unit (4) via a heat dissipating path (6), and a return path (7) that connects the heat dissipating unit and the heat receiving unit (4); and that cools the heat-generating element by circulating the refrigerant, accompanied by a gas-liquid two-phase change, through the heat receiving unit (4), the heat dissipating path (6), the heat dissipating unit, and the return path (7), in order. The heat receiving unit (4) comprises a heat receiving plate (11) that is in contact with the heat-generating element and absorbs heat, and a heat receiving cover (14) that covers the surface of the heat receiving plate (11) and forms a heat receiving space (13). In addition, a check valve (18) that opens when the pressure in the return path (7) is greater than the pressure in the heat receiving space (13) is provided between the return path (7) and the heat receiving unit (4), and a hydrophilic surface treated membrane (22) is formed in a recess (24) provided on the surface of the heat receiving plate (11).
