Abstract

A three-dimensional heat absorbing device including: an airtight member defining an outer appearance of the three-dimensional heat absorbing device; a first space connected to each other inside the airtight member in a three-dimensional lattice structure; and a second space constituting a space not occupied by the first space among an internal space of the airtight member. In the device, at least one of the first space and the second space forms a channel for working fluid steam, and a wick to which liquefied working fluid is absorbed are provided along inner surfaces of the channel.

First claim

1 . A three-dimensional heat absorbing device comprising:
an airtight member defining an outer appearance of the three-dimensional heat absorbing device; a first space connected to each other inside the airtight member in a three-dimensional lattice structure; and a second space constituting a space not occupied by the first space among an internal space of the airtight member, wherein at least one of the first space and the second space forms a channel for working fluid steam, and a wick to which liquefied working fluid is absorbed are provided along inner surfaces of the channel.

2 . The three-dimensional heat absorbing device of claim 1 , wherein at least one of the first space and the second space is filled with the wick, and the phase-changed working fluid is moved in a boundary between the first space and the second space.

3 . The three-dimensional heat absorbing device of claim 1 , wherein a boundary between the first space and the second space is configured by a wall.

4 . The three-dimensional heat absorbing device of claim 3 , wherein the wick is provided on an inner surface of the wall of the first space and the second space, and the first space and the second space forms a channel for the working fluid steam.

5 . The three-dimensional heat absorbing device of claim 4 , wherein the working fluid is a homogeneous or heterogeneous material.

6 . The three-dimensional heat absorbing device of claim 3 , wherein a wick is provided on an inner surface of a wall of any one of the first space and the second space to form the channel for the working fluid steam.

7 . The three-dimensional heat absorbing device of claim 6 , wherein an inside of a space not forming the channel for the working fluid steam among the first space and the second space is filled with a phase change material.

8 . The three-dimensional heat absorbing device of claim 7 , further comprising:
a porous heat transfer member immersed in the phase change material.

9 . The three-dimensional heat absorbing device of claim 8 , wherein the porous heat transfer member is any one of foamed metal, lattice metal, and woven metal.

10 . The three-dimensional heat absorbing device of claim 6 , wherein a solid heat dissipation member is provided in a space not forming the channel for the working fluid steam among the first space and the second space.

11 . The three-dimensional heat absorbing device of claim 10 , wherein the heat dissipation member is any one of porous metal, solid metal, and a cooling fin.

12 . The three-dimensional heat absorbing device of claim 1 , wherein the wick is any one of a metal net, felt, fiber, and permeable porous solid.

13 . The three-dimensional heat absorbing device of claim 1 , wherein the working fluid is any one of water, ammonia, ethanol, helium, argon, nitrogen, lead, silver, and lithium.

14 . The three-dimensional heat absorbing device of claim 8 , wherein the phase change material is any one of paraffin, lauric acid, and salt hydrate.

15 . The three-dimensional heat absorbing device of claim 1 , wherein the boundary between the first space and the second space is a flat surface or a curved surface.
