STRUCTURE, AND METHOD FOR MANUFACTURING SAME

1 . A structure comprising:

a heat insulating layer;

an evaporator formed using a space portion between a plurality of plate materials provided on one surface side of the heat insulating layer;

a condenser formed using a space portion between a plurality of other plate materials provided on the other surface side of the heat insulating layer;

a vapor flow path for guiding refrigerant vapor generated as a result of evaporation at the evaporator to the condenser; and

a liquid refrigerant flow path for guiding a liquid refrigerant generated as a result of condensation at the condenser to the evaporator, wherein

the evaporator has a wick layer for evaporating the refrigerant stored on a lower portion side with heat from one surface side of the evaporator while suctioning up the refrigerant by capillarity and holding the refrigerant, and

the evaporator and the condenser are installed so as to overlap by ½ or more in the direction in which the wick layer suctions up the refrigerant.

2 . The structure according to claim 1 , further comprising blocking means for blocking at least one of the vapor flow path and the liquid refrigerant flow path.

3 . The structure according to claim 1 , wherein the wick layer is formed by solidifying powder non-uniform in particle size in a particle size range of 150 micrometers or less.

4 . The structure according to claim 1 , further comprising a latent heat storage material on the one surface side of the evaporator.

5 . The structure according to claim 1 , wherein the wick layer has a heat resistance of 850° C. or higher.

6 . A structure manufacturing method comprising:

a joining step of partially joining four or more plate materials;

a space forming step of forming a wick powder introduction space by performing pressurization in a high-temperature environment of 800° C. or higher between the four or more plate materials partially joined in the joining step;

a powder introduction step of introducing wick layer forming powder into the introduction space formed in the space forming step; and

a solidification step of solidifying the powder introduced in the powder introduction step in a state where the high-temperature environment is maintained.

7 . A structure manufacturing method comprising:

a powder placement step of placing wick layer forming powder in at least one place between four or more plate materials; and

a joining and solidification step of partially joining the four or more plate materials by pressurization in a high-temperature environment of 800° C. or higher and solidifying the powder placed in the powder placement step by the high-temperature environment and pressurization.
