Vehicle Interior Heat Exchanger

Abstract

The thermal efficiency of a heat exchanger which is disposed on a blowing path in a vehicle interior and operates as a condenser is enhanced. In a vehicle interior heat exchanger 1 which functions as a condenser, a pair of tube groups 13 A and 13 B have a plurality of stacked cooling medium circulation tubes 11 and are arranged side by side in a blowing direction so as to face each other, on one end side in an axial direction of the cooling medium circulation tubes 11 , an inlet side header tank 14 A which has a cooling medium inlet tube 14 a and to which each of the cooling medium circulation tubes 11 of the tube group 13 A on one side is connected for communication and an outlet side header tank 14 B which has a cooling medium outlet tube 14 b and to which each of the cooling medium circulation tubes 11 of the tube group 13 B on the other side is connected for communication are arranged separately and with a space therebetween, and on the other end side in the axial direction of the cooling medium circulation tubes 11 , a single intermediate header tank 15 to which each of the cooling medium circulation tubes 11 of the pair of tube groups 13 A and 13 B is connected for communication is disposed.

1 . A vehicle interior heat exchanger of a vehicle heat pump apparatus, which is disposed on a blowing path in a vehicle interior and functions at least as a condenser,
 wherein a pair of tube groups which have a plurality of stacked cooling medium circulation tubes are arranged side by side in a blowing direction of the blowing path so as to face each other,   wherein, on one end side in an axial direction of the cooling medium circulation tubes, an inlet side header tank, which has a cooling medium inlet and to which each of the cooling medium circulation tubes of the tube group on one side is connected for communication, and an outlet side header tank, which has a cooling medium outlet and to which each of the cooling medium circulation tubes of the tube group on the other side is connected for communication, are arranged separately and with a space therebetween, and   wherein, on the other end side in the axial direction of the cooling medium circulation tubes, a single intermediate header tank to which each of the cooling medium circulation tubes of the pair of tube groups is connected for communication is disposed.   
     
     
         2 . A vehicle interior heat exchanger of a vehicle heat pump apparatus, which is disposed on a blowing path in a vehicle interior and functions at least as a condenser,
 wherein a pair of tube groups which have a plurality of stacked cooling medium circulation tubes are arranged side by side in a blowing direction of the blowing path so as to face each other,   wherein, on one end side in an axial direction of the cooling medium circulation tubes, an inlet side header tank, which has a cooling medium inlet and to which each of the cooling medium circulation tubes of the tube group on one side is connected for communication, and an outlet side header tank, which has a cooling medium outlet and to which each of the cooling medium circulation tubes of the tube group on the other side is connected for communication, are arranged in one body via a heat insulation layer, and   wherein, on the other end side in the axial direction of the cooling medium circulation tubes, a single intermediate header tank to which each of the cooling medium circulation tubes of the pair of tube groups is connected for communication is disposed.   
     
     
         3 . A vehicle interior heat exchanger of a vehicle heat pump apparatus, which is disposed on a blowing path in a vehicle interior and functions at least as a condenser,
 wherein a pair of tube groups which have a plurality of stacked cooling medium circulation tubes are arranged side by side in a blowing direction of the blowing path so as to face each other,   wherein, on one end side in an axial direction of the cooling medium circulation tubes, an inlet side header tank, which has a cooling medium inlet and to which each of the cooling medium circulation tubes of the tube group on one side is connected for communication, and an outlet side header tank, which has a cooling medium outlet and to which each of the cooling medium circulation tubes of the tube group on the other side is connected for communication, are arranged in one body,   wherein the cooling medium inlet and the cooling medium outlet are formed at end portions on sides opposite to each other in a stacking direction of the cooling medium circulation tubes of the tanks, and   wherein, on the other end side in the axial direction of the cooling medium circulation tubes, a single intermediate header tank to which each of the cooling medium circulation tubes of the pair of tube groups is connected for communication is disposed.   
     
     
         4 . The vehicle interior heat exchanger according to  claim 1 ,
 wherein the plurality of cooling medium circulation tubes are arranged in a vertical direction and the cooling medium outlet is disposed at a lower end portion of the outlet side header tank.   
     
     
         5 . The vehicle interior heat exchanger according to  claim 1 ,
 wherein the cooling medium inlet and the cooling medium outlet are connected to an external cooling medium pipe on a vehicle exterior.
