摘要： PROBLEM TO BE SOLVED: To provide a heat exchanger capable of improving the efficiency of heat exchange without enlarging the size of a condenser.SOLUTION: A plurality of heat exchangers 13 are disposed on a condenser 3 arranged on a lateral surface of a vehicle 10. The heat exchangers 13 are formed on a contour of a flat plate shape extended in the vertical direction of the vehicle and are inclined relative to the longitudinal direction of the vehicle such that the front side in the longitudinal direction of the vehicle is directed to the outside in the vehicle-width direction. Thereby, traveling air W generated by the travelling of the vehicle 10 easily penetrates between the heat exchangers 13. As the result, even when the condenser 3 is arranged on the lateral surface of the vehicle, heat exchange on the heat exchangers 13 is facilitated and the degradation of the efficiency of heat exchange can be suppressed.
