[0002] The air conditioning system of an electric vehicle usually includes a high-voltage water heater or a high-voltage air heater. The gas blown in by the blower is heated by the water heater or the air heater and then blown into the cockpit to provide a warm air function. When the crew cabin needs to be heated, the heater starts to heat up, and after heat exchange with the air generated by the blower, the air with a certain temperature is blown into the cockpit, thereby realizing the cockpit heating or defrosting function. During the use of the above air conditioning system, as long as there is a heating demand in the crew cabin, the heater will be required to start working. Although the heater has different power gears, the different power gears only adjust the amount of warm air entering the crew cabin, and there is still the problem of unconcentrated heating and energy waste. The most typical energy waste is: even if there is only one driver in the cockpit, when he issues a heating request, the heater will still start heating inside the air conditioning main unit, and then enter the cockpit through the various air outlets on the dashboard, heating the entire area of the cockpit, and consuming huge energy.
[0003] However, compared with electric vehicles, air conditioning and heating systems are high-power electrical appliances.

[0020] In order to further explain the technical means and effects adopted by the present invention to achieve the predetermined invention purpose, the specific implementation methods, structures, features and effects of the display panel and automobile air conditioning device proposed by the present invention are described in detail below in conjunction with the accompanying drawings and preferred embodiments:
[0021] The present invention provides an automobile air conditioning device, such as Figure 1 As shown, Figure 1 An automobile air conditioning device according to an embodiment is shown. Figure 1 The arrow in the middle indicates the direction of gas flow. The automobile air conditioning device of this embodiment includes an air conditioning main unit 11, an air outlet, a first air duct 15 and a heater 17. The air conditioning main unit 11 is connected to the first air duct 15, and the air outlet is connected to the first air duct. There are at least two first air ducts 15 and heaters 17, respectively, and each first air duct 15 is provided with a heater 17. Each heater 17 is independently started and stopped.
[0022] In this embodiment, the heater is separated from the air conditioner main unit and is independent of the air conditioner main unit, and each heater can be individually controlled to start and stop. On the one hand, the number of heaters to be turned on can be individually controlled according to the number of people in the passenger compartment, and the temperature of each area in the passenger compartment can be independently controlled, and it is efficient and energy-saving, thereby improving the endurance of the car. On the other hand, the volume of the air conditioner main unit can be greatly reduced, the structure is simple, and the manufacturing cost of the automobile air conditioner can be reduced. The automobile air conditioner of this embodiment can be applied to electric vehicles or fuel vehicles, and is particularly suitable for electric vehicles, which is particularly important for improving the endurance of electric vehicles, which is currently a pain point.
[0023] In this embodiment, please refer to Figure 2 The air conditioner main unit 11 includes a blower 112, which is used to blow air toward the heater 17 in the first air duct 15, so that the air is heated by the heater 17 to become warm air, and then blown out from the air outlet to heat the passenger compartment of the car. Specifically in this embodiment, there is one blower 112, and the same blower 112 blows air to each heater 17 at the same time. The cold air blown by the blower 112 is heated to warm air after passing through the working heater 17. It can be understood that in other embodiments, there can also be multiple blowers 112, and each blower 112 blows air to one heater 17.
[0024] Specifically, the blower 112 may include a plurality of gears, and the incoming air volume and wind speed may be controlled by adjusting the gears of the blower 112 .
[0025] In this embodiment, the air conditioner main unit 11 also includes a refrigeration element, through which cold air can be generated, and the cold air can be blown out from the air outlet to cool the passenger compartment of the car. Specifically, the refrigeration element may include an evaporator 114 and a compressor 115, and the evaporator 114 is connected to the compressor 115. The compressor 115 is used to compress the low-temperature, low-pressure refrigerant into a high-temperature, high-pressure refrigerant, thereby increasing its temperature and pressure, releasing coldness, and achieving cooling. The evaporator 114 is used to convert the hot gas refrigerant into a low-temperature, low-pressure refrigerant through heat absorption, and reduce the indoor temperature after absorbing the heat in the room.
[0026] In this embodiment, the air conditioner host 11 further includes a controller 117, which is connected to the blower 112, the compressor 115 and the heater 17 to control the cooling or heating of the automobile air conditioner. Each heater 17 is connected to the controller 117, which is used to control each heater 17 to start and stop independently, that is, whether one heater 17 is working has nothing to do with the status of other heaters 17, and the working status of each heater 17 can be controlled separately.
[0027] In this embodiment, please refer to Figure 3 , an air outlet is provided on the dashboard 19 of the car. Specifically, at least two air outlets are provided on the dashboard 19 of the car, and the driver's seat and the co-driver's seat of the car face at least one air outlet respectively. More specifically, a first air outlet 131 is provided on the dashboard 19, and the first air outlet 131 is connected to the first air duct 15. A second air outlet 133 is also provided on the dashboard 19, and the second air outlet 133 is connected to the first air outlet 131 through the second air duct 21. In other words, the first air outlet 131 is directly connected to the first air duct 15, and the second air outlet 133 is indirectly connected to the first air duct 15 through the second air duct 21 and the first air outlet 131. Specifically, the second air duct 21 is arranged inside the dashboard 19.
[0028] Specifically, the first air outlet 131 and the second air outlet 133 are respectively provided at the positions on the left and right sides corresponding to the driving seat of the car on the instrument panel 19, and the first air outlet 131 and the second air outlet 133 are respectively provided at the positions on the left and right sides corresponding to the co-pilot seat of the car on the instrument panel 19, and each first air outlet 131 is connected to a first air duct 15. In addition, an air outlet may also be provided in front of the rear seat of the car. Specifically, at least two third air outlets 135 are provided in front of the rear seat of the car, and both sides of the rear seat of the car face at least one third air outlet 135 respectively. The third air outlet 135 is connected to the first air duct 15. In this way, the passenger compartment of the car can be divided into four areas, and whether to provide heating to the four areas can be controlled by controlling whether the four heaters 17 are working according to the number of people in the passenger compartment or the needs of the passengers, so as to meet the heating use needs in different situations. For example, when there is only the driver in the car, only the upper left heater 17 can be turned on; when there are only people in the driver's seat and the co-pilot seat in the car, only the two upper left and upper right heaters 17 can be turned on; when the car is full of people, all four heaters 17 can be turned on.
[0029] Specifically, each air outlet is provided with an air outlet switch to control whether the corresponding air outlet is discharging air. A heater switch may also be provided at each air outlet to control the start and stop of the heater 17 corresponding to the corresponding air outlet, so that the occupants in each seat can conveniently control whether the corresponding area is heated by themselves without the need for the driver to operate. Of course, a heater switch for controlling the start and stop of each heater 17 may also be provided at the corresponding position of the driving position of the instrument panel 19, so as to facilitate the control of whether the corresponding area is heated when there are no occupants in the corresponding area.
[0030] In this embodiment, the heater 17 may be a PTC air heater, and of course the heater 17 may also be a water heater or other types of heaters, which are not limited here. Specifically in this embodiment, there may be four heaters 17, and there may also be four first air ducts 15, with one heater 17 in each first air duct 15. It is understood that the heater 17 may also be designed to be other numbers as needed.
[0031] Specifically, the heater 17 can be a low-voltage air heater. Of course, the heater 17 can also be a low-voltage water heater. The power of each heater 17 can be 1000W to 1500W, and the voltage can be 12V to 48V. The low-voltage heater with lower power also produces less noise when working, so it can improve the comfort of the car.
[0032] For details, please refer to Figure 4The heater 17 is tiltedly arranged in the first air duct 15, so that the heater 17 with a larger cross-sectional area can be installed in the first air duct 15 with a smaller cross-sectional area to improve the efficiency of the air intake heat exchange. Generally speaking, the cross-sectional size of the first air duct 15 is generally 10cm*10cm. After the original large-volume high-voltage heater is split into a small-volume low-voltage heater 17, its smaller size enables the heater 17 to be placed in the first air duct 15 with a smaller cross-sectional size.
[0033] In this embodiment, the first air duct 15 communicating with the first air outlet 131 is disposed inside the instrument panel 19 .
