HEAT EXCHANGER FOR A VENTILATING APPARATUS

摘要

A hat exchanger for a ventilating apparatus is provided to reduce pressure loss by change the air flow into turbulent flow when the indoor air or outdoor air passes the heat exchanger with scratched or uneven surface. A hat exchanger(20) for a ventilating apparatus comprises heat exchange layers(211,221), guide ribs(212,222), and a turbulence forming part(30). The guide ribs are alternately layered on the heat exchange layer to form an air passage. The turbulence forming part is provided on a surface of the guide rib coming in contact with the air flowing through the air passage to generate turbulence, comprising at least more than one regular or irregular protrusion on the surface of the guide rib.
