Method for manufacturing evaporator wicks

Abstract

To provide a wick for an evaporator which can be stably manufactured and has high performance.SOLUTION: A wick for an evaporator comprises a columnar body part 52a formed by lamination of multiple porous metal plates on one another in an axial direction S. The body part 52a includes: a hollow part 52b which is formed in a columnar interior and is opened at an end part on a first side in an axial direction S and not opened at an end part on a second side; and a plurality of steam grooves 52c formed at intervals in a circumferential direction of a columnar external peripheral face, the steam grooves 52c being formed in the axial direction S from an end part of the second side in the axial direction S and not formed at the end part on the first side in the axial direction S.SELECTED DRAWING: Figure 4

Claims

[Claim 1] It comprises a cylindrical main body formed by stacking multiple porous metal plates in the axial direction, The main body is, A hollow portion is formed inside the cylindrical shape, opening at the first end in the axial direction and not opening at the second end, A plurality of steam grooves are formed at intervals in the circumferential direction on the cylindrical outer surface, the steam grooves being formed from the second end in the axial direction toward the axial direction and not formed at the first end in the axial direction, A method for manufacturing an evaporator wick, comprising: A lamination process in which multiple porous metal plates are stacked to form a laminate, A cutting step is performed to cut the laminate formed in the lamination step into a cylindrical shape to form the base material of the main body, A molding process to form the main body portion by forming the hollow portion and the steam groove in the base material, Equipped with, A method for manufacturing evaporator wicks. [Claim 2] Electrical discharge machining is used in the cutting process and the die-cutting process. The electrical conditions for the electrical discharge machining are set to a range that can avoid delamination of the metal plates laminated in the lamination process. A method for manufacturing an evaporator wick according to claim 1.
