[0037] Embodiment 1

[0038] Please refer to Figure 1 、 Figure 2 、 Figure 6 and Figure 7 As shown in, this embodiment provides a vehicle air - conditioning 30 system, including a control box 10, a blower 108, and a defroster 20. The control box 10 is provided with a first air outlet 101, a second air outlet 102, a first air inlet 103, and a second air inlet 104. The first air outlet 101 and the second air outlet 102 are arranged on one end side of the control box 10, and the first air inlet 103 and the second air inlet 104 are arranged on the other end side of the control box 10. In the middle of the control box 10, a heating device 105, a heat - exchange device 106, and an air - conditioning evaporator core 107 are arranged side by side. The pipeline of the heat - exchange device 106 is communicatively connected to the exhaust heat pipe of the vehicle power assembly 1. The power supply interface of the heating device 105 is arranged on the outer side surface of the control box 10. The blower 108 is arranged inside the control box 10, and the blower 108 is arranged between the first air outlet 101 and the heating device 105. Inside the defroster 20, there is a first air - outlet cavity 201 communicated with the first air outlet 101 and a second air - outlet cavity 202 communicated with the second air outlet 102.

[0039] Specifically, a control box 10 body and a defroster 20 are designed. Air is discharged through the communication with the first air outlet 101 and the second air outlet 102. The defroster 20 can be arranged on the instrument panel of the vehicle cab. If the air outlet on the first air - outlet cavity 201 faces the direction of the front windshield, the effect of defrosting the front windshield can be achieved; if the air outlet of the second air - outlet cavity 202 is designed to face the direction of the driver's seat, air can be blown to the driver's face to achieve the purpose of different air discharges as required.

[0040] For the cooling method of the air flow, the air-conditioning evaporation core 107 can be connected to the air conditioner 30, and cold air can be provided via the control box 10 to cool the cab and provide a comfortable temperature environment for the driver. At the same time, the heat exchange device 106 is connected to the vehicle's power assembly 1 to perform heat exchange on the waste heat generated by the vehicle's power, further heating the flowing air, and achieving the purpose of heating the air flow through waste heat recovery. Then, through the blowing of the blower 108, the purpose of blowing hot air for defrosting can be achieved, and the effect of blowing hot air or defrosting inside the vehicle can be realized.

[0041] When the heat recovered from waste heat is insufficient, the heating device 105 can also be used for heating to heat the air flow to the required temperature, effectively utilize waste heat, reduce the energy consumption of the vehicle, and at the same time, ensure the performance of the vehicle, provide the required hot air, and have good practicability and energy-saving performance.

[0042] Specifically, the heating device 105 in this embodiment can be a high-voltage PTC core or a hydrothermal pipeline, that is, heating is carried out through the high-voltage PTC core; or, heating is carried out by passing hot water through a coil or a serpentine pipe.

[0043] In this embodiment, the heat exchange device 106 can be a heat exchanger 1062. For example, it is connected to the vehicle's power assembly 1 through a water pipe to realize the circulation of the water circuit, and the part located in the control box 10 can be in the form of a coil or a serpentine pipe to recover the waste heat of the vehicle's power assembly 1 and reduce the energy consumption of the vehicle.

[0044] As Figure 8 shown, in another embodiment, the heat exchange device 106 includes a water heating core 1061, a heat exchanger 1062 arranged on the output pipe of the power assembly 1, a recovery pipe 1063 connecting the inlet of the water heating core 1061 and the outlet of the heat exchanger 1062, a return pipe 1064 connecting the outlet of the water heating core 1061 and the inlet of the heat exchanger 1062, and valves 1065 are arranged on the recovery pipe 1063 and the return pipe 1064.

[0045] Specifically, the water heating core 1061 is arranged in the control box 10, and the heat exchanger 1062 is installed on the output pipeline of the power assembly 1 to obtain the discharged waste heat, that is, the water in the water heating core 1061 is heated by the waste heat, and a circulating flow is formed through the recovery pipe 1063 and the return pipe 1064 to realize the transportation of the heated water into the control box 10 to heat the air flow. In terms of operation, the recovery pipe 1063 and the return pipe 1064 can be switched on and off through the valve 1065 (the valve 1065 can be a solenoid valve) to achieve the purpose of closing waste heat recovery and provide operation flexibility.

[0046] As Figure 2 、Figure 3 , Figure 4 and Figure 5 In this embodiment, a first air damper 109 for opening or closing the first air outlet 101 and a second air damper 110 for opening or closing the second air outlet 102 are provided in the control box 10. The air damper can be rotated by a motor to drive the sealing plate to cover or enclose the air outlet, achieving the effect of closing the air outlet. In this way, by controlling the motor, the opening and closing operations of the air outlet can be controlled, realizing the effect of automatic operation. Therefore, it can be switched on or off as required during use. Combining the above description, when the first air outlet 101 is opened and the second air outlet 102 is closed, defrosting air is blown to the front windshield; on the contrary, face air is blown. The first air outlet 101 and the second air outlet 102 can also be opened simultaneously for air blowing to meet the required operations.

[0047] In this embodiment, an air intake damper 111 for opening the first air intake 103 and closing the second air intake 104 or closing the first air intake 103 and opening the second air intake 104 is provided in the control box 10. The air intake damper 111 can be a device that drives a partition plate to swing through a servo motor or a motor. The first air intake 103 and the second air intake 104 are symmetrically arranged on both sides of the control box 10. When the partition plate is in sealed contact with the inner wall of the control box 10 to separate a triangular space (sealing can be achieved by arranging silicone or rubber on the edge of the partition plate), and the first air intake 103 is located on the side of the triangular space, the purpose of closing the first air intake 103 is achieved, while the second air intake 104 is opened; similarly, the second air intake 104 is closed and the first air intake 103 is opened.

[0048] During use, the first air intake 103 can be connected to the outside of the vehicle through a pipeline. At this time, the first air intake 103 is opened and the second air intake 104 is closed, or it is arranged facing the outside of the vehicle. In this way, the outside air flow can be guided into the control box 10 for heating, that is, external circulation air blowing can be carried out. The second air intake 104 is connected to the inside of the vehicle through a pipeline. When the first air intake 103 is closed and the second air intake 104 is opened, the internal circulation of the air flow inside the vehicle is carried out.

[0049] As Figure 8 shown, in this embodiment, a radiator 1066 connected to the output pipe of the power assembly 1 is also provided. The setting of the radiator 1066 can ensure the safety of the operation of the power assembly 1. That is, when hot air or defrosting operations are carried out in the vehicle, the waste heat on the power assembly 1 can be dissipated through the radiator 1066 to ensure the safety of the equipment operation.

[0050] As Figure 1As shown, in this embodiment, an independently provided air conditioner 30 is further included. The heat exchange pipes of the air conditioner 30 are communicatively connected to the air conditioner evaporation core 107. The refrigerant pipeline of the air conditioner 30 can be communicatively connected to the vehicle compartment, such as in the cab and / or the compartment, to provide cooling effect for the vehicle.

[0051] Embodiment 2

[0052] As Figure 1 shown, this embodiment also provides a truck, including the on-vehicle air conditioner 30 system described in Embodiment 1, which can be used, for example, on new energy trucks. For example, the on-vehicle air conditioner 30 system can be communicatively connected to the cab to provide defrosting, cooling or hot air blowing for the driver. At the same time, the waste heat in the power assembly 1 can be recovered, which can reduce the energy consumption of the vehicle, that is, reduce the use cost of the vehicle and improve the practicability.

[0053] As mentioned above, the above are only the preferred specific embodiments of the present utility model, but the protection scope of the present utility model is not limited thereto. Any changes or substitutions that can be easily thought of by those skilled in the art within the technical scope disclosed by the present utility model should be covered within the protection scope of the present utility model.
