Claims

[Scope of utility model registration request]

At least a portion of the fins held between the parallel partition plates are bent so that the partition plate side portions that contact the partition plates and the fin surface portions that connect the partition plates to each other are alternately formed. A plate fin heat exchanger with offset fins in which the fin surface portions are intermittently offset, characterized in that a protrusion that causes turbulence is provided on the inside of the side portion of the partition wall plate of the fin. exchanger.
