The heat pump system in a vehicle may perform different functions in the condenser 200 under different conditions, and the temperature of the air that needs to flow through may also be different. In the related art, the radiator 300 and the condenser 200 of the heat pump system are mechanically integrated, the condenser 200 is arranged in front of the radiator 300, and air flows from the condenser 200 to the radiator 300, so that a good refrigerating effect can be obtained, and the refrigerating requirement under a high-temperature environment using scene can be met.

For another example, the heat exchange air duct shell 100, the radiator 300, the air inlet adjusting assembly 400 and the air outlet adjusting assembly 500 all have the same multi-deformation cross section, and the condenser 200 has different multi-deformation or circular cross sections. Those skilled in the art can adjust the specific structures of the heat exchange air duct case 100, the condenser 200, the radiator 300, the air inlet adjustment assembly 400, and the air outlet adjustment assembly 500 in consideration of the size of the heat radiating area, the flow rate and smoothness of the air in the first and second air ducts 210 and 310, and the like.

In this scenario, as shown in fig. 5, the second air duct 310 between the air inlet 110 and the radiator 300 is opened, and the first air duct 210 between the air inlet 110 and the condenser 200 is closed by the cooperation of the air inlet movable grille 420 and the air inlet fixed grille 410; the second air duct 310 between the air outlet 120 and the radiator 300 is closed, and the first air duct 210 between the air outlet 120 and the condenser 200 is opened by the cooperation of the air outlet movable grille 520 and the air outlet fixed grille 510.
