Cooling apparatus boiling and condensing refrigerant with low height and easily assembled

A cooling apparatus comprising:

• a multilayer structure of a plurality of plate members;
• wherein a fluid path communicating with outside through communication ports is formed in said multilayer structure of said plurality of said plate members;
• and
• wherein the heat of a heat-generating member mounted on the surface of said cooling apparatus is discharged into a heat receiving medium flowing in and out by way of said communication ports and flowing in said fluid path thereby to cool said heat-generating member;
• and
• wherein said communication ports are formed in the surface at the end portions of said plate members along the direction in which said plate members extend.

A cooling apparatus boiling and condensing a refrigerant, comprising:

• a refrigerant bath section having a first heat-generating member mounted on the surface thereof for storing a refrigerant therein;
• a refrigerant diffusion section for diffusing said refrigerant boiled by the heat received from said first heat-generating member;
• and
• a heat exchange section interposed between said refrigerant bath section and said refrigerant diffusion section and including a first space communicating with said refrigerant bath section and said refrigerant diffusion section and through which said refrigerant flows, and a second space through which an external cooling fluid flows;
• wherein said heat exchange section includes a multilayer structure of a plurality of tabular members having a plurality of apertures corresponding to said first space and said second space;
• and
• wherein said refrigerant bath section is formed integrally by forging or casting.
