Abstract
In an electronic component cooling unit, one surface of a cold plate, on the other surface of which an electronic component is mounted, is covered with a cover to form a tank section in which a refrigerant is stored, a container pipe is extended from the cover in such a manner that the container pipe is communicated with the tank section, a wick pole is fitted in the container pipe so that a plurality of axial passageways are formed in the container pipe, and air is removed from the tank section and the axial passageways.
Claims3
An electronic component cooling unit, comprising:
- a cold plate, an electronic component being mounted on one surface of said cold plate;
- a cover member covering the other surface of said cold plate to constitute a tank section in which a refrigerant is stored;
- a container pipe extending from said cover member in such a manner that said container pipe is communicated with said tank section;
- and
- a wick pole being fitted in said container pipe, said wick pole including an axial portion extending along a central longitudinal axis of said container pipe, and a plurality of radial protrusions extending outwardly from said axial portion, so that a plurality of axial passageways are formed in said container pipe, said tank section and said axial passageways being evacuated into a vacuum.
