Abstract

A heat conducting member includes a housing provided with a space inside, and a working medium in the space. The housing includes a first region, a second region located on one side in one direction perpendicular or substantially perpendicular to a thickness direction of the housing across the first region, and a third region located on another side in the one direction across the first region. The first region includes a first end portion connected to the second region and a second end portion connected to the third region. The first end portion is at a position in the thickness direction different from the second end portion.

First claim

What is claimed is:

1 . A heat conducting member comprising:
a housing provided with a space inside; and a working medium in the space; wherein the housing includes:
a first region;
a second region located on one side in one direction perpendicular or substantially perpendicular to a thickness direction of the housing with respect to the first region; and
a third region located on another side in the one direction with respect to the first region;
the first region includes: a first end portion connected to the second region; and a second end portion connected to the third region; the first end portion has a different position in the thickness direction than the second end portion.

2 . The heat conducting member according to claim 1 , wherein
the first region of the housing is inclined with respect to the thickness direction; and at least one of the second region and the third region of the housing is located to extend along the one direction.

3 . The heat conducting member according to claim 2 , wherein
the housing includes an upper plate and a lower plate opposing each other in the thickness direction; the upper plate includes an upper inclined portion inclined with respect to the thickness direction; the lower plate includes a lower inclined portion inclined with respect to the thickness direction; the first region includes the upper inclined portion and the lower inclined portion; and the upper inclined portion and the lower inclined portion oppose each other across a portion of the space.

4 . The heat conducting member according to claim 3 , wherein
the upper plate includes:
a first upper coupling portion coupled to the upper inclined portion; and
a second upper coupling portion coupled to the upper inclined portion on a side opposite to the first upper coupling portion;
the lower plate includes:
a first lower coupling portion coupled to the lower inclined portion; and
a second lower coupling portion coupled to the lower inclined portion on a side opposite to the first lower coupling portion;
the second region includes the first upper coupling portion and the first lower coupling portion that oppose each other; the third region includes the second upper coupling portion and the second lower coupling portion that oppose each other; and the first region has a height in a normal direction of the lower inclined portion that is below a height of the second region in a normal direction of the first lower coupling portion and a height of the third region in a normal direction of the second lower coupling portion.

5 . The heat conducting member according to claim 3 , wherein at least one of the upper inclined portion and the lower inclined portion includes a protrusion protruding in the thickness direction of the housing.

6 . The heat conducting member according to claim 1 , wherein the housing has a width in the one direction in the first region that is longer than a height of the housing in the thickness direction.

7 . The heat conducting member according to claim 1 , wherein when the working medium flows as gas in a flow path in the housing in a direction from the second region toward the third region through the first region, a sum of an area of the first region and an area of the third region is larger than an area of the second region when the housing is viewed from the thickness direction.

8 . The heat conducting member according to claim 1 , wherein when the working medium flows as gas in a flow path in the housing in a direction from the second region toward the third region through the first region, a sum of an area of the first region and an area of the third region is smaller than an area of the second region when the housing is viewed from the thickness direction.

9 . The heat conducting member according to claim 1 , wherein the first region is located along a direction inclined with respect to the one direction when viewed from the thickness direction.

10 . The heat conducting member according to claim 1 , further comprising a wick structure located over the first region, the second region, and the third region in the housing.
