HEAT EXCHANGER WITH STRUCTURE OF EXPANDED POLY PROPYLENE

摘要

PURPOSE: A total enthalpy heat exchanger case made of an expandable polypropylene resin with a vertically separable cover plate and a sliding joint flange is provided to rapidly and simply assemble a total enthalpy heat exchanger by vertically coupling a cover plate to a main body and coupling a sliding joint flange to a through hole. CONSTITUTION: A total enthalpy heat exchanger case made of an expandable polypropylene resin with a vertically separable cover plate and a sliding joint flange comprises a main body (10) and cover plates (20). Through holes formed on one and the other surfaces of the main body form an intake and exhaust path. The top ends of the through holes are open, and the inner surfaces have fitting grooves. Joint flanges have a shape corresponding to the through holes, and the outer surfaces thereof have fitting protrusions to be vertically slid to the through holes. Auxiliary through holes are formed at right angles to the intake and exhaust path, and auxiliary joint flanges are coupled thereto. Connection pipes made of an expandable polypropylene resin are coupled to the joint flanges or auxiliary joint flanges and are used as pipe connectors. [Reference numerals] (AA,BB) Pipe connector
