Vehicle air conditioning system has guide covering heat exchanger surface on fan side with surface that alters direction of air flow against heat exchanger sides , whereby guide surface extension intersects choke surface

摘要

The vehicle air conditioning system has a housing (2) forming an air channel (1) containing a fan (3) and a heat exchanger (4) on the air output side of the fan in the channel that exchanges heat between the air and the heat exchange medium, an air inflow chamber (10), a choke surface (21) and an air guide (23) covering a surface of the heat exchanger on the fan side and with a surface that alters the direction of the air flow against the sides of the heat exchanger, whereby an extension of the guide surface intersects the choke surface.
