Title:
HEAT EXCHANGER AND ITS MANUFACTURING METHOD
Document Type and Number:
WIPO Patent Application WO/2007/119394
Kind Code:
A1
Abstract:
A heat exchanger for exchanging heat through heat transfer plates by flowing a primary airflow and a secondary airflow in air passages. The heat exchanger comprises a unit element having a heat transfer plate and an air passage formed between the heat transfer plates by stacking the unit elements. Each of the unit elements is structured by molding a space rib for holding the space between the heat transfer plates integrally with a shield rib for shielding the leak of the airflows by use of a resin. The unit element includes an error detection part which can easily detect an error in stacking when the unit elements are stacked.
