Claims

[Claims for Utility Model Registration] 1. A multi-stage plate-fin type heat exchanger in which a heat insulating space is formed between a plate fin attached to a lowermost wooden pipe and a plate fin attached to an upper wooden pipe. vessel. 2. Utility model registration as set forth in claim 1, in which a plate fin attached to a wood pipe in the lowermost tier and a plate fin attached to a wood pipe in an upper tier are separated from each other to form a heat insulating space. Multi-stage pre-7 toffin type heat exchanger. 3 The plate fin attached to the wood pipe at the lowest level and the plate fin attached to the wood pipe at the upper level than the wood pipe are each made of one piece, and the space between the wood pipe at the lowest level and the wood pipe at the upper level is punched out. A multi-stage plate-fin type heat exchanger according to claim 1, which forms a heat insulating space. 4. The multi-tiered utility model according to claim 1, which is formed by forming a heat insulating space by setting the interval between the plate fins attached to the wood pipes in the lowermost tier to be larger than the interval between the plate fins attached to the wood pipes in the upper tier. Plate fin type heat exchanger.
