Title:
PLATE-TYPE HEAT EXCHANGER AND HEAT PUMP DEVICE
Document Type and Number:
WIPO Patent Application WO/2020/136863
Kind Code:
A1
Abstract:
This plate-type heat exchanger 3 is formed by rotating, by 180 degrees, heat transfer plates 40 and 41 180-degrees and stacking the heat transfer plates 40 and 41 and constitutesto configure a first flow passagesth 63 through which water W flows and a second flow passagesth 64 through which a refrigerant R flows. Elongated sections Fa, and Fb are formed at one long side of main plate sections 70a, and 70b, and protruding sections 61, and 62 are formed at the other long side. The protruding section 62 of each heat transfer plateblade 41 is configured so as to be in contact with a wall section 71a and the elongated section Fa of each heat transfer blade plate 40. Therefore, whereby only the refrigerant R and not the water W comes into contact with side sections H1 that comprise wall sections 71a, and 72b. As a result, a temperature sensor 14 joined to the wall section 71a canis able to exhibit improved temperature detection accuracy of the refrigerant R.
