When the air conditioning system of the vehicle is in operation, the air flow of the first heat exchanger assembly 30 flows in from the first air inlet 40 and the front air inlet 12, is pressurized by the first fan 31 to perform work, and is blown to the first heat exchanger 32, and because the outlet of the first fan 31 has the diffusion function, the air flow can uniformly flow to the first heat exchanger 32 after being blown out from the first fan 31, the air flow exchanges heat through the first heat exchanger 32, and takes heat out, and is discharged through the air channel formed by the top plate 10a and the first heat exchanger 32 and the first air outlet 11, so that primary air flow circulation is completed. Due to the coanda effect, the air flow will flow smoothly in the direction extending through the top plate 10a, ensuring that each air flow cycle is performed with low wind resistance.
From the above description, it can be seen that the above embodiments of the present application achieve the following technical effects: the vehicle air conditioning system mainly comprises a first heat exchanger component, a compressor, an electric element, a second heat exchanger component, a top cover and an air conditioning body. The first air inlet at the top of the condensing section is an annular air inlet formed by a top cover arranged at the opening at the top, so that the first fan is ensured to have enough air inlet quantity; the top cover extends from the top opening to two sides of the vehicle, and the width of the top cover is larger than that of the top opening, so that the effect of shielding rain and snow is guaranteed, the first fan is prevented from being blocked or frozen and cannot operate due to freezing rain, snow burst and the like, and the reliability of the vehicle is improved; meanwhile, the edge of the top cover slightly warps upwards to form an eave-like structure, and the air flow guiding device has the effects of guiding air flow and reducing wind resistance. The advantage that the longitudinal space along the automobile body is big has been fully utilized, the overall arrangement is gone on with second heat exchanger subassembly and first heat exchanger subassembly front and back, makes the setting space of second heat exchanger subassembly and first heat exchanger subassembly wider, ensures that electrical components and wind channel in second heat exchanger subassembly and the first heat exchanger subassembly have sufficient layout space, has guaranteed that air conditioning system has good refrigeration and heating effect. The first fan and the first heat exchanger are separated by the second partition plate, so that air flows are guaranteed to flow into the first fan only from the first air inlet and the front air inlet, and are discharged from the first air outlet on the other side, the inlet air and the outlet air are not interfered with each other, short circuit of the air flows can be effectively prevented, and the vehicle air conditioner is guaranteed to run under the optimal working condition. The front side air inlet is positioned at the front end of the vehicle, so that the head-on wind speed in the running process can be effectively utilized, and the static pressure overcoming capacity of the fan is increased.
The above description is only of the preferred embodiments of the present application and is not intended to limit the present application, but various modifications and variations can be made to the present application by those skilled in the art. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application should be included in the protection scope of the present application.
