Heat exchanger for vehicle air conditioning system

摘要

A counter-flow heat exchanger (100) for a vehicle air conditioning system includes a first lateral tank (102) having an inlet chamber (106) and an outlet chamber (108). The first lateral tank (102) includes an inlet port (110) fluidly connected to the inlet chamber (106) and an outlet port (112) fluidly connected to the outlet chamber (108). The outlet port (112) is positioned adjacent an uppermost portion of the first lateral tank (102) for reducing air pockets. A second lateral tank (104) is laterally spaced apart from the first lateral tank (102). A first set of tubes fluidly connects the inlet chamber (106) of the first lateral tank (102) to the second lateral tank (104) A second set of tubes fluidly connects the second lateral tank (104) to the outlet chamber (108) of the first lateral tank (102).
The expression counter-flow heat exchanger used in this document refers to a two-pass cross-flow heat exchanger, whereby the fluid flow inside the first set of tubes is reversed by the second tank, so that the fluid flow in the second set of tubes is in counter direction to the first one.
