Title:
COOLER AND COOLER MANUFACTURING METHOD
Document Type and Number:
Japanese Patent JP2020106156
Kind Code:
A
Abstract:
To provide a cooler capable of reducing deterioration in cooling efficiency due to inclination of the cooler.SOLUTION: A cooler has a heat receiving part having a space inside, a liquid-phase pipe that supplies liquid-phase refrigerant to the heat receiving part, a gas-phase pipe that discharges gas-phase refrigerant from the heat receiving part, and a spacer arranged inside the heat receiving part. The spacer has a larger specific gravity than the liquid-phase refrigerant. Also, the spacer has a shape capable of moving along the bottom surface of a heat receiver. When the heat receiving part is inclined, the spacer moves to the lower side of the heat receiver. Here, since the spacer has a larger specific gravity than the liquid-phase refrigerant 2, it gathers on the bottom surface on the lower side of the heat receiver. Then, the spacer allows the liquid-phase refrigerant to spread to the high side of the heat receiver by the excluded volume, thereby performing highly uniform cooling.SELECTED DRAWING: Figure 1
