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.
Claims32
A heat exchanger comprising:
- a first header tank partitioned into a 1-1st area and a 1-2nd area inside;
- 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.
4 more elements
A vehicle air conditioning system comprising:
- a refrigerant loop including a condenser and an evaporator;
- and
- a heat exchanger in which one or both of a first heat exchange medium and a second heat exchange medium selectively flow, the first heat exchange medium being cooled by exchanging heat with a refrigerant through the evaporator for indoor cooling, and the second heat exchange medium being heated by exchanging heat with the refrigerant through the condenser for indoor heating.
