Document Type and Number:
WIPO Patent Application WO/2013/183113
Kind Code:
A1
Abstract:
Provided is a heat exchanger that satisfactorily maintains heat exchange efficiency, has a simple structure, can be inexpensively produced, and is capable of improving long-term reliability of a device as a result of prevention of fluid leakage. A plate-type heat exchanger (1) comprising: a plurality of heat transfer plates (5, 5); a plurality of inner fins (9, 9) having a first flow path and a second flow path alternately formed between each pair of heat transfer plates (5, 5), and arranged in the first flow path or second flow path corresponding to each; and a plurality of leakage prevention plates (7, 7). Passage holes through which fluid is fed are provided in the leakage prevention plates. The inner fins (9) for the first flow paths and the inner fins (9) for the second flow paths are provided so as to have different heat transfer surface areas.
