EBULLIENT COOLING DEVICE
First Claim
1. An ebullient cooling device for cooling a heating body, comprising:
- at least first and second cooling channel blocks, both arranged in a vertical direction, comprising;
a cooling fin that causes coolant to flow in the vertical direction;
a vapor discharge path formed on a side of the cooling fin that is opposite to a side in contact with a heating body;
a partition positioned between the cooling fin and the vapor discharge path; and
an opening portion provided at the partition, between the first and second cooling channel blocks;
a guiding portion provided between the first and second cooling channel blocks, the guiding portion formed as a portion of the partition to project from an edge of the opening portion towards the heating body contacting side of the cooling fin, and guiding a bubble generated in the first cooling channel block to the vapor discharge path by preventing the bubble from proceeding into the second cooling channel block; and
a fluid supply pipe provided between the first and second cooling channel blocks for supplying the coolant to the second cooling channel block,wherein a front edge of the guiding portion contacts with the fluid supply pipe.

Abstract
An ebullient cooling device having a simple structure and capable of limiting the bubbles to an appropriate volume. The ebullient cooling device for cooling a heat generating element is provided with a plurality of vertically arranged cooling channels comprising a lower channel (2), a middle channel (3) and un upper channel (4). Each cooling channel has cooling fins (12) for guiding a refrigerant to flow in a vertical direction, and a vapor discharge path (16) formed at the side of the cooling fins (12) that is opposite the side in contact with the heat generating element. Furthermore, flow path partition/vapor discharge guiding plates (18) are provided between the cooling channels so that the bubbles that have been generated are guided to the vapor discharge path (16) and prevented from moving into the subsequent cooling channel.
