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. In a fin type heat exchanger, high heat is applied to the fins in at least one of the full length of the passage near the spacer bar, the full width of the passage near the fluid inlet, and the full width of the passage near the fluid outlet in the high-temperature side fluid passage and/or the low-temperature side fluid passage. A plate fin type heat source characterized by using means for making the density or performance higher than other parts in order to obtain heat transferability and/or means for making the density or performance lower in other parts in order to obtain low heat transferability. exchanger.
