Title:
HEAT EXCHANGING ELEMENT
Document Type and Number:
WIPO Patent Application WO/2008/038475
Kind Code:
A1
Abstract:
A heat exchanging element having a laminated structure is provided for a heat
exchanging type ventilating system or other air conditioning apparatuses.
The heat exchanging element has improved heat exchanging efficiency by eliminating
drift in a ventilation flue while keeping flow strength, and an airflow leakage
due to peeling between a heat transfer plate and other members is prevented. A
flow straightening section is provided for eliminating drift generated in the
ventilation flue due to different ventilation resistances caused by difference
of lengths of flow channels divided by a flow channel dividing section, and for
giving prescribed flow speed distribution to a counterflow section.
