Title:

HEAT TRANSPORT DEVICE AND METHOD FOR MANUFACTURING SAME

Document Type and Number:

WIPO Patent Application WO/2020/003412

Kind Code:

A1

Abstract:

The present invention addresses the problem of providing a heat transport device which has a high heat transmission rate because one flow passage meanders and the interval between two flow passages is narrow, and the other fluid flows through the narrow space between the flow passages, and as a result thereof, a reduction in size, a reduction in weight, or a reduction in thickness, etc. can be achieved. This problem is solved by a heat transport device comprising first flow passages through which a first fluid flows, and second flow passages through which a second fluid flows, wherein a cross-section A satisfying the following [Requirement 1] to [Requirement 3] can be achieved. [Requirement 1] The cross-section A is a cross-section perpendicular to the second flow passages. [Requirement 2] In the cross-section A, the holes of second flow passages are separated by meandering partition plates and are disposed in a layered manner. Two adjacent partition plates are a partition plate B and a partition plate C, and when comparing a point α, which is the top point of a mountain in the partition plate B closest to the partition plate C, and a point β, which is the bottom point of a valley in the partition plate C closest to the partition plate B, the point α is closer to the partition plate C side than the point β. [Requirement 3] The first flow passages are present inside the partition plates.
