<P>PROBLEM TO BE SOLVED: To improve heat efficiency of a heat exchanger to be placed in a vehicle interior draft passage and to operate as a condenser. <P>SOLUTION: A vehicle interior heat exchanger 1 functions as a condenser, which is constituted as follows. A pair of tube groups 13A, 13B respectively with a plurality of refrigerant flow tubes 11 stacked in layers are placed side by side in an air blowing direction so as to face each other; an inlet-side header tank 14A with a refrigerant inlet pipe 14a and with the respective refrigerant flow tubes 11 of the tube group 13A communicatively connected thereto, and an outlet-side header tank 14B with a refrigerant outlet pipe 14b and with the respective refrigerant flow tubes 11 of the tube group 13B communicatively connected thereto are placed separately and mutually spaced apart, on one end side in the axial direction of the refrigerant flow tubes 11; and one intermediate header tank 15 with the respective refrigerant flow tubes 11 of the pair of tube groups 13A, 13B communicatively connected thereto is placed on the other end side in the axial direction of the refrigerant flow tubes 11. <P>COPYRIGHT: (C)2012,JPO&INPIT |
