Title:
HEAT EXCHANGER
Document Type and Number:
WIPO Patent Application WO/2019/043802
Kind Code:
A1
Abstract:
Provided is a heat exchanger that is compact and inexpensive and that is highly efficient and pressure-resistant. This heat exchanger 10 performs heat exchange between hydrogen and a refrigerant. Refrigerant flow paths and hydrogen flow paths are provided in a layered shape and in an alternating manner in a Z direction orthogonal to the flow path direction in portions at which heat exchange is performed. The refrigerant flow paths have ten refrigerant upstream narrow paths 48 and ten refrigerant downstream narrow paths 50 that are arranged in parallel in a Y direction, and honeycomb parts 52 that are provided between the refrigerant upstream narrow paths 48 and the refrigerant downstream narrow paths 50. First branching/merging parts 54 and second branching/merging parts 56 are provided in an alternating manner to the honeycomb parts 52. In the first branching/merging parts 54, a previous flow path is branched into two partial flow paths 60, 60, and a next flow path is formed by the merging together of adjacent partial flow paths 60, 60. In the second branching/merging parts 56 as well, a flow path is branched into two partial flow paths 62, 62 and adjacent partial flow paths 62, 62 are merged in the same manner. The hydrogen flow paths also have similar honeycomb parts 52.
