20100232110 | COOLING APPARATUS AND POWER CONVERTER - A cooling apparatus with high strength and good heat radiation characteristics. In the cooling apparatus, a heat exchanger is joined to an evaporator disposed on the lower side in a face to face manner; a containing unit of the heat exchanger includes a heat exchanger high temperature liquid outlet, and a two-phase fluid inlet in a joint portion with the evaporator; an outlet header of the heat exchanger includes an intermediate liquid outlet at a joint portion with the evaporator; and the evaporator includes a two-phase fluid outlet in the joint portion with the heat exchanger in opposition to the two-phase fluid inlet of the containing unit, and including an intermediate liquid inlet at the joint portion with the heat exchanger in opposition to the intermediate liquid outlet of the outlet header. | 09-16-2010 |
20120024513 | COOLING STRUCTURE, HEATSINK AND COOLING METHOD OF HEAT GENERATOR - A cooling structure includes a heat dissipation structure having a heat generator and a heatsink that is adhered through an insulating adhesive layer to at least a surface of the heat generator that faces a cooling fluid and made of a metal foil having the flexibility. A fluid flow path is disposed outside of the heat dissipation structure so that the cooling fluid flowing inside thereof and the heatsink may directly come into contact. Further, a fine recess is disposed on a surface of the heatsink that directly comes into contact with the cooling fluid. | 02-02-2012 |
