In-Chamber Condenser

Abstract

An interior condenser ( 1, 32 ) which is accommodated in an HVAC unit of a vehicle air-condoning heat pump system, the interior condenser including: a heat exchange core ( 6 ) that is composed of stacked tubes ( 2 ) and fins ( 4 ); a refrigerant inflow/outflow-side tank ( 10, 34 ) to which one end portions of the tubes are connected; a refrigerant turn-side tank ( 12 ) to which the other end portions of the tubes are connected; a partition wall ( 14 ) that separates an inner portion of the refrigerant inflow/outflow-side tank into a refrigerant inflow chamber ( 16 ) and a refrigerant outflow chamber ( 18 ); a refrigerant inlet tube ( 28 ) that is connected to the refrigerant inflow/outflow-side tank to communicate with the refrigerant inflow chamber; and a refrigerant outlet tube ( 30 ) that is connected to the refrigerant inflow/outflow-side tank to communicate with the refrigerant outflow chamber, wherein the refrigerant outlet tube is connected to the refrigerant inflow/outflow-side tank at a position below the core.

1 . An interior condenser which is accommodated in an HVAC unit of a vehicle air-conditioning heat pump system, the interior condenser comprising:
 a heat exchange core that is composed of stacked tubes and fins;   a refrigerant inflow/outflow-side tank to which one end portions of the tubes are connected;   a refrigerant turn-side tank to which the other end portions of the tubes are connected;   a partition wall that separates an inner portion of the refrigerant inflow/outflow-side tank into a refrigerant inflow chamber and a refrigerant outflow chamber;   a refrigerant inlet tube that is connected to the refrigerant inflow/outflow-side tank to communicate with the refrigerant inflow chamber; and   a refrigerant outlet tube that is connected to the refrigerant inflow/outflow-side tank to communicate with the refrigerant outflow chamber,   wherein the refrigerant outlet tube is connected to the refrigerant inflow/outflow-side tank at a position below the core.   
     
     
         2 . The interior condenser according to  claim 1 ,
 wherein the core is composed of a forward-side core section in which a refrigerant performs heat exchange after passing through the refrigerant inflow/outflow-side tank from the refrigerant inlet tube, and a return-side core section in which the refrigerant performs heat exchange after passing through the forward-side core section and the refrigerant turn-side tank, and   the refrigerant inlet tube and the refrigerant outlet tube are connected to the refrigerant inflow/outflow-side tank at a point-symmetrical position with respect to the partition wall as a symmetrical axis, and at a position overlapping each other as viewed from a direction perpendicular to the partition wall.   
     
     
         3 . The interior condenser according to  claim 2 ,
 wherein the refrigerant inlet tube and the refrigerant outlet tube are connected to the refrigerant inflow/outflow-side tank at a line-symmetrical position with respect to the partition wall as the symmetrical axis.
