AI Technical Summary
In total heat exchangers, the air duct baffles in front of the heat exchange core are mostly formed by sheet metal bending, resulting in poor flow field uniformity on the core surface, local eddies, high wind speeds in some areas, blind air supply zones in some areas, low enthalpy efficiency, and high overall resistance.
An integrally molded foam component is used as the windward side air duct component of the core. The design includes guiding protrusions and flow guide surfaces to guide the airflow to the heat exchange core more quickly, reduce eddies and swirls, improve the uniformity of the air field, and balance the air duct resistance by adjusting the shape and size of the air duct.
It improves the uniformity of the airflow at the heat exchange core, increases enthalpy efficiency, reduces overall resistance, reduces noise, avoids the generation of eddies and vortices, increases net fresh air rate, and reduces production costs.
