Claims

[Claims for Utility Model Registration] Plate for heat exchange between adjacent high-temperature side fluid passages and low-temperature side fluid passages by interposing fins between tube plates to form fluid passages in a desired direction with spacer bars and stacking them. A plate fin type heat exchanger characterized in that, in the fin type heat exchanger, high pressure loss fins are used for the internal fins of the outermost layer passage except for the passage entrance part.
