COOLING STRUCTURE
First Claim
1. A cooling structure having an installation surface for placement of a target object to be cooled, a plurality of cooling fins disposed side by side on a reverse side of the installation surface, and a cooling passage for cooling the cooling fins with a liquid refrigerant that flows from an inlet port into the cooling passage and is discharged from an outlet port, wherein:
- the cooling passage has a first surface on which the cooling fins are disposed, a second surface confronting the first surface, and a wall assembly disposed between the first surface and the second surface, the cooling passage being constructed as a channel having a length that is longer than a straight line interconnecting the inlet port and the outlet port;
the wall assembly has a first wall that extends from the second surface toward the first surface, and a second wall that extends in parallel with the first wall from the first surface to a height beyond a top of the first wall; and
a distance between the first wall and the second wall is shorter than a distance between the adjacent cooling fins.

Abstract
As a cooling structure, a cooling device has a configuration that comprises a mounting surface for a member to be cooled, a cooling fin provided on a rear surface side of the mounting surface, and a cooling passage for cooling the cooling fin with a liquid refrigerant, wherein the liquid refrigerant is caused to flow from a flow inlet to the cooling passage and is discharged from a discharge outlet. The cooling passage comprises a first surface provided with the cooling fin, a second surface opposing the first surface, and a wall portion provided between the first surface and the second surface and is configured into a channel longer than a channel connecting the flow inlet and the discharge outlet in a straight line. The wall portion has a first wall portion extending from the second surface to the first surface, and a second wall portion extending in parallel with the first wall portion from the first surface to a height exceeding a top portion of the first wall.
