HEAT EXCHANGER

摘要

A compact plate lamination heat exchanger (3) having a channel member constituted by stacking and bonding metal plates (1, 2) provided with a groove (9), a primary system channel and a secondary system channel for heat exchange formed of the groove (9) between the metal plates (1, 2) of the channel member, and exchange heat capacity per unit area not lower than 10 MWt/m³ is used under high temperature high pressure conditions where the differential pressure between primary system fluid and secondary system fluid is 4-7 MPa, and the maximum temperature is 500-900°C. Thickness of the metal plates (1, 2) is 0.3 times or more of the equivalent diameter of channel, and the channel pitch along the plate thickness direction of the metal plates (1, 2) is 0.5 times or more of the equivalent diameter of channel.
