Title:
PLATE TYPE HEAT EXCHANGER
Document Type and Number:
Japanese Patent JP2021042929
Kind Code:
A
Abstract:
To prevent local heat of a second heat exchange body adjacent to an uppermost stream heat exchange body in a flow channel of second fluid.SOLUTION: In a plate type heat exchanger, adjacent heat exchange bodies 10 are formed so that a projection surface of a through-hole 13 of one of the heat exchange bodies 10 does not overlap on a through-hole of the other heat exchange body 10. Respective heat exchange bodies 10 in an upstream heat exchange group 9a including an uppermost stream heat exchange body 10a are formed so that the total opening area of multiple through-holes 13 becomes larger than that of a downstream side heat exchange group 9b located downstream from the upstream heat exchange group 9a.SELECTED DRAWING: Figure 5
