Title:
PLATE-TYPE HEAT EXCHANGER AND REFRIGERATING AIR-CONDITIONING DEVICE
Document Type and Number:
WIPO Patent Application WO/2010/106717
Kind Code:
A1
Abstract:
A plate-type heat exchanger having increased strength obtained with the heat exchange performance of the plate-type heat exchanger maintained. A plate-type heat exchanger (20) is formed by layering plates (2, 3) on top of one another. Each of the plates (2, 3) has formed in the four corners thereof a first inlet hole (5) serving as the inlet for a first fluid, a first outlet hole (6) serving as the outlet for the first fluid, a second inlet hole (7) serving as the inlet for a second fluid, and a second outlet hole (8) serving as the outlet for the second fluid. Each of the plates (2, 3) has formed between the plate (2, 3) and the plate layered thereon a first flow path for causing the first fluid to flow therethrough and a second flow path for causing the second fluid to flow therethrough, and the first fluid and the second fluid are caused to exchange heat between each other. In each of the plates (2, 3), the length (L1) in the longitudinal direction thereof is four or more times the length (L2) in the lateral direction thereof.
