Abstract

A vehicle air conditioning system provides a heat exchanger and a vehicle air conditioning system comprising same, which can simplify the overall structure and can easily perform cooling/heating of air for air conditioning and dehumidification heating by using an integrated heat exchanger which is selectively supplied with low- and high-temperature cooling water by a supply valve to perform heat exchange.

First claim

The invention claimed is:

1. A heat exchanger comprising:

a second header tank spaced apart from the first header tank at a predetermined distance in parallel;
first tubes and second tubes each having both ends fixed to the first header tank and the second header tank, respectively, the first tubes communicating with the 1-1st area and the second tubes communicating with the 1-2nd area;
a supply valve for selectively supplying a first heat exchange medium and a second heat exchange medium to the 1-1st area and the 1-2nd area, respectively, wherein the first heat exchange medium or the second heat exchange medium diverges before supply;
a first inlet pipe provided between the 1-1st area of the first header tank and the supply valve;
a second inlet pipe provided between the 1-2nd area of the first header tank and the supply valve,
wherein through the supply valve, the first heat exchange medium is supplied to both the first inlet pipe and the second inlet pipe, the second heat exchange medium is supplied to both the first inlet pipe and the second inlet pipe, or the first heat exchange medium and the second heat exchange medium are supplied to the first inlet pipe and the second inlet pipe, respectively.

2. The heat exchanger of claim 1 , wherein the first heat exchange medium and the second heat exchange medium are coolants that are mixable with each other, while having different temperatures.

3. The heat exchanger of claim 2 , wherein the first header tank includes a 1-1st header and a 1-1st tank forming the 1-1st area, and a 1-2nd header and a 1-2nd tank forming the 1-2nd area.

4. The heat exchanger of claim 3 , wherein an assembly including the 1-1st header and the 1-1st tank and an assembly including the 1-2nd header and the 1-2nd tank are spaced apart from each other at a predetermined distance.

5. A vehicle air conditioning system comprising:
an air conditioning case;
the heat exchanger of claim 4 , the heat exchanger being provided in the air conditioning case; and
