Abstract: Provided is a method for manufacturing a wick, which facilitates control over capillarity of the wick. A method for manufacturing a wick according to the present invention includes: a step of supplying material powder containing metal powder onto a base; a step of heating the material powder on the base to obtain a sintered compact; and a step of rolling the sintered compact. In this situation, when the material powder supplied onto the base is heated to form the sintered compact, the sheet-shaped sintered compact can be formed. Further, when the sintered compact is rolled, a void ratio of the sintered compact can be controlled after forming the sintered compact, thereby controlling the capillarity of the wick 1.

Abstract: The present disclosure provides a method for manufacturing a heat exchanger including an evaporating body configured to absorb heat from outside and evaporate a liquid-phase working fluid into a gas phase while moving the working fluid by capillary forces. The method includes steps of: forming a recess in a plate surface of a first plate member, the first plate member being plate-shaped; applying a powder-containing material to a predetermined region in the recess; solidifying the material applied to the predetermined region to form the evaporating body; and covering the recess having the evaporating body formed thereon with a second plate member, the second plate member being plate-shaped, and securing the first plate member to the second plate member.
