Title:
プレート式熱交換器及び冷凍空調装置
Document Type and Number:
Japanese Patent JP5106453
Kind Code:
B2
Abstract:
It is aimed to enhance the strength of a plate heat exchanger while maintaining the heat exchange capability of the plate heat exchanger. A plate heat exchanger 20 is configured with a plurality of stacked plates 2 and 3. Each of the plates 2 and 3 includes at four corners thereof a first inlet hole 5 which acts as an inlet for a first fluid, a first outlet hole 6 which acts as an outlet for the first fluid, a second inlet hole 7 which acts as an inlet for a second fluid, and a second outlet hole 8 which acts as an outlet for the second fluid. Each of the plates 2 and 3 and an adjacent plate define therebetween a first flow path for passing the first fluid and a second flow path for passing the second fluid, so as to exchange heat between the first fluid and the second fluid. In each of the plates 2 and 3, a longitudinal length L1 is 4 or more times a lateral length L2.
