Heat exchanger

Abstract

A heat exchanger has an inflow port through which refrigerant flows, a cooling outflow port through which the refrigerant flows out during a cooling operation, and a heating outflow port through which the refrigerant flows out during a heating operation. A distance between the inflow port and the heating outflow port is shorter than a distance between the inflow port and the cooling outflow port.

1 . A heat exchanger for a heat pump system that performs a cooling operation and a heating operation, the heat exchanger comprising:
 a heat exchanging portion configured to perform heat exchange between a refrigerant and an outside air during the cooling operation and the heating operation;   a refrigerant adjustment unit that is integrally joined with a liquid reservoir that stores liquid refrigerant, and that switches a flow of the refrigerant during the cooling operation and the heating operation;   an inflow port into which the refrigerant flows;   a cooling outflow port through which the refrigerant flows out during the cooling operation; and   a heating outflow port through which the refrigerant flows out during the heating operation, wherein   a distance between the inflow port and the heating outflow port is shorter than a distance between the inflow port and the cooling outflow port.   
     
     
         2 . The heat exchanger according to  claim 1 , wherein
 a heat transfer member is provided between the inflow port and the heating outflow port.   
     
     
         3 . The heat exchanger according to  claim 2 , wherein
 the inflow port, the heating outflow port, and the heat transfer member are configured by a single connector component.   
     
     
         4 . The heat exchanger according to  claim 3 , wherein
 the connector component is connected so that a space between the inflow port and the heating outflow port is filled with the heat transfer member.   
     
     
         5 . The heat exchanger according to  claim 3 , wherein
 the cooling outflow port is provided in a component different from the connector component.   
     
     
         6 . The heat exchanger according to  claim 1 , wherein
 the inflow port and the heating outflow port are arranged such that a flow direction of the refrigerant at the inflow port is opposite to a flow direction of the refrigerant at the heating outflow port.   
     
     
         7 . The heat exchanger according to  claim 1 , wherein
 the inflow port, the heating outflow port, and the cooling outflow port are arranged in this order in a longitudinal direction of the liquid reservoir.
