Abstract

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.

Claims Analysis

Total Claims: 4
Claim 1
Independent Claim 129 words
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.
Claim 2
Dependent Claim 129 words
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.
Claim 3
Dependent Claim 26 words
An electronic component cooling unit as claimed in claim 1, wherein said other surface of said cold plate has a recess which constitutes said tank section.
Claim 4
Dependent Claim 19 words
An electronic component cooling unit as claimed in claim 2, wherein a bottom of said recess has fine roughness.
