  • Heat exchanger for refrigerant circuitry
    Patent number: 10017028
    Abstract: The present invention relates to the heat exchanger 1 of refrigerant circuitry of an air-conditioning system for a vehicle, which enables a bidirectional pass flow. The air-conditioning system is configured to perform a combined operation of cooling device mode and heat pump mode, the heat exchanger 1 is formed in the form of a multi-pass, and the flow direction of a refrigerant varies depending on operation mode. The first heat exchanger 1 formed in the form of a multi-pass includes header pipes 2 and 3, flow paths assigned to respective passes, and means configured to partition an internal volume space of one or more header pipes 2 and 3 into independent regions. A first pass of the heat exchanger 1 has a greater flow cross section and greater heat exchange surface than the last pass.
