Description

Technical Field

[0001] The present application relates to the technical field of automobiles, and particularly relates to an automobile air conditioner, a control method and a control device for an automobile air conditioner, and an automobile. Background Art

[0002] The automatic driving technology of automobiles is the development direction of automotive technology. An automobile with an automatic driving function is usually provided with an automatic driving module. Since a large amount of heat is generated by each component of the automatic driving module during high-load operation, an additional heat dissipation device is required to dissipate heat from the automatic driving module. In related technologies, the cold air generated by the automobile air conditioner can be guided to the automatic driving module to cool down the automatic driving module.

[0003] For this cooling method, if too much cold air is guided to the automatic driving module, the amount of cold air entering the passenger compartment will become smaller, thereby affecting the air conditioning effect of the passenger compartment; if too little cold air is guided to the automatic driving module, the cooling effect on the automatic driving module will be unsatisfactory. Therefore, how to reasonably allocate the air volume to simultaneously meet the refrigeration requirements of the automatic driving module and the passenger compartment has become a technical problem to be solved. Summary of the Invention

[0004] Embodiments of the present application provide an automobile air conditioner, a control method and a control device for an automobile air conditioner, and an automobile, which can reasonably allocate the air volume, so that the automobile air conditioner can simultaneously meet the refrigeration requirements of the automatic driving module and the passenger compartment, and is beneficial to improving the user's driving experience.

[0005] In a first aspect, an automobile air conditioner is provided, including:

[0006] A housing having an air inlet and an air outlet, and an evaporator is provided inside the housing;

[0007] An air distribution duct is provided inside the housing and has a duct inlet and a duct outlet. The duct inlet is used to introduce the air-conditioned air passing through the evaporator, and the duct outlet is used to discharge the air-conditioned air to the air outlet;

[0008] An air guiding pipe is connected to the housing and communicated with the air distribution duct. The air guiding pipe is used to lead out the air-conditioned air in the air distribution duct to a data processing module and perform heat exchange with the data processing module;

[0009] An adjusting air door is used to adjust the opening degree of the duct outlet to distribute the air-conditioned air in the air distribution duct between the air outlet and the air guiding pipe.

[0010] In the embodiment of the present application, an air distribution duct is arranged inside the housing of the automotive air conditioner. The air duct inlet of the air distribution duct can introduce the air-conditioning air from the evaporator, and the air duct outlet of the air distribution duct can discharge the air-conditioning air in the air duct to the passenger compartment through the air outlet; the air induction pipe is connected to the housing and communicated with the air distribution duct, and the air induction pipe can discharge the air-conditioning air in the air distribution duct to the data processing module to cool the module. An adjustment damper is arranged on the air duct outlet of the air distribution duct. The adjustment damper can adjust the opening degree of the air duct outlet, and can distribute the air-conditioning air in the air distribution duct between the air outlet and the air induction pipe, so as to realize the on-demand distribution of the air-conditioning air between the passenger compartment and the data processing module, so that the automotive air conditioner can simultaneously meet the refrigeration requirements of the passenger compartment and the data processing module, and both the passenger compartment and the data processing module can be effectively cooled, thus being beneficial to improving the user's driving experience.

[0011] In a possible design, the automotive air conditioner further includes:

[0012] A heating air duct, arranged in parallel with the air distribution duct inside the housing, and a warm air core is arranged upstream of the air duct outlet in the heating air duct;

[0013] A temperature damper for distributing the air-conditioning air passing through the evaporator between the air distribution duct and the heating air duct.

[0014] Through the above settings of the heating air duct, the warm air core, the temperature damper, etc., and combined with the flexible switching and matching of the working positions of the adjustment damper and the temperature damper, the automotive air conditioner has more functions. At this time, different working modes of the air conditioner can be achieved by controlling the working positions of the adjustment damper and the temperature damper, so that the automotive air conditioner can also meet the usage requirements in more scenarios such as heating the passenger compartment, dehumidifying the passenger compartment, and heating the data processing module, thereby improving the performance and product competitiveness of the automotive air conditioner.

[0015] In a possible design, the air duct outlet is arranged on the partition wall between the air distribution duct and the heating air duct.

[0016] Through the above settings, the air duct outlet of the air distribution duct can face the heating air duct, and the warm air in the heating air duct is more likely to enter the air distribution duct, which can simplify the internal structure design and control logic of the air conditioner. At this time, by controlling the working positions of the adjustment damper and the temperature damper, the heating or cooling of the data processing module can be realized, and the switching of the working modes of the automotive air conditioner is more simple and efficient.

[0017] In a possible design, the automotive air conditioner further includes:

[0021] The outlet air door is used to distribute the conditioned air after heat exchange with the data processing module between the exhaust duct and the return air duct.

[0022] By setting up a return air duct, the air-conditioned wind after heat exchange with the data processing module can be discharged into the passenger compartment. At this time, the heat generated by the data processing module when it is working can be used to heat the passenger compartment. When there is a heating demand in the passenger compartment, the heat of the data processing module can be recovered. The heat of the data processing module can be directly returned to the passenger compartment for direct heating, reducing the heat dissipation loss of the pipeline, which can improve the energy efficiency of the whole vehicle and increase the cruising range in low temperature environments. By setting up an outlet damper to distribute the air-conditioned wind after heat exchange with the data processing module between the exhaust duct and the return air duct, the air-conditioned wind after heat exchange can be discharged into the environment or introduced into the passenger compartment according to the actual situation, thereby making the use of the automobile air conditioner provided in the embodiment of the present application more flexible and more adaptable, and able to meet the use needs in more scenarios.

The implementation manners described below by referring to the accompanying drawings are exemplary and are only used to explain the present application and should not be construed as a limitation to the present application.

[0087] It should also be noted that in the embodiments of the present application, the same reference numeral represents the same component or the same part. For the same parts in the embodiments of the present application, only one of the parts or components may be marked with the reference numeral in the figure. It should be understood that for other identical parts or components, the reference numeral is equally applicable.

[0088] An autonomous vehicle is an intelligent vehicle that uses a high-performance computer to replace humans in driving. Autonomous driving technology involves multiple aspects such as environmental perception, high-precision positioning, behavior decision-making, path planning, and vehicle control technology. All of these technologies involve a large amount of computing processing and have very high requirements for the real-time nature of data calculation and transmission. Therefore, current L4 / L5 level autonomous vehicles are equipped with high-performance autonomous driving modules at the vehicle end to meet the high computing power requirements of various software units such as perception, positioning, decision-making, and planning, so as to ensure the real-time nature of data processing and transmission to achieve automatic control of the vehicle.

[0089] During the high-load operation of the autonomous driving module, a large amount of heat is generated, resulting in an increase in temperature. Excessive temperature will affect the working performance of the autonomous driving module. Therefore, it is necessary to take certain measures to cool down the autonomous driving module. In related technologies, the cold air generated by the vehicle air conditioner can be guided to the autonomous driving module to achieve cooling of the autonomous driving module.

[0090] The inventor noticed in engineering practice that for this cooling method, if too much cold air is guided to the autonomous driving module, the amount of cold air entering the passenger compartment will become smaller, which will in turn affect the air conditioning effect of the passenger compartment; if too little cold air is guided to the autonomous driving module, the cooling effect on the autonomous driving module will be unsatisfactory. Therefore, how to reasonably distribute the air volume to simultaneously meet the refrigeration requirements of the autonomous driving module and the passenger compartment has become a technical problem to be solved.

[0091] Based on this, the embodiment of the present application provides an automotive air conditioner. A air distribution duct is provided in the housing of the automotive air conditioner. The inlet of the air distribution duct can introduce air-conditioning air from the evaporator, and the outlet of the air distribution duct can discharge the air-conditioning air in the air distribution duct to the passenger compartment; an air guiding pipe is connected to the housing and communicates with the air distribution duct, and the air guiding pipe can discharge the air-conditioning air in the air distribution duct to the autonomous driving module to cool the module. An adjusting damper is provided at the outlet of the air distribution duct, and the adjusting damper can adjust the opening degree of the outlet, and thus can distribute the air-conditioning air between the passenger compartment and the autonomous driving module as needed, can simultaneously meet the refrigeration requirements of the passenger compartment and the autonomous driving module, and both the passenger compartment and the autonomous driving module can be effectively cooled, which is beneficial to improving the user's driving experience.

[0092] The automotive air conditioner provided by the embodiment of the present application can be applied to various types of vehicles. For example, it can be an internal combustion locomotive, an intelligent electric vehicle or a hybrid vehicle, or the vehicle can also be a vehicle of other power types such as a hydrogen energy vehicle, etc. The embodiment of the present application does not limit this.

[0093] The vehicle may be an autonomous vehicle, which may be a vehicle with partial autonomous driving functions or a vehicle with full autonomous driving functions. That is to say, the level of autonomous driving of the autonomous vehicle may be classified into no automation (L0), driving assistance (L1), partial automation (L2), conditional automation (L3), high automation (L4), or full automation (L5) with reference to the classification standard of the Society of Automotive Engineers (SAE).

[0094] As a specific example, the vehicle may be Figure 1 the electric vehicle 1000 in Figure 1 which is a schematic diagram of the overall structure of the electric vehicle 1000 provided by an embodiment of the present application. As Figure 1 shown, the electric vehicle 1000 provided by an embodiment of the present application includes a vehicle body 400, a battery pack 500, and a plurality of wheels 600.

[0095] The vehicle body 400, as the main part of the electric vehicle 1000, includes basic components such as doors, windows, seats, a chassis 410, and a powertrain system located inside the vehicle body 400. The battery pack 500 is detachably suspended below the chassis 410, and a plurality of wheels 600 (such as 4, 6, or 8, etc.) are rotatably distributed on the chassis 410. The battery pack 500 serves as the power source of the electric vehicle 1000, providing electrical energy for the powertrain system. The powertrain system is connected to the wheels 600 and is used to convert the electrical energy of the battery pack 500 into driving force and transmit it to the wheels 600 to drive the electric vehicle 1000 to travel.

[0096] Optionally, the powertrain system includes a motor and a transmission. The battery pack 500 supplies power to the motor, and the output shaft of the motor is connected to the wheels 600 through the transmission. The motor drives the wheels 600 to rotate, thereby being able to drive the electric vehicle 1000 to travel.

[0097] Optionally, the electric vehicle 1000 provided by an embodiment of the present application may be a passenger vehicle (such as a small car or a passenger bus), or may also be various types of freight trucks. At this time, the interior of the vehicle body 400 has a passenger space for passengers to ride and / or a cargo space for carrying goods.

[0098] Optionally, the electric vehicle 1000 provided in the embodiments of the present application may be various types of vehicles capable of being driven by electricity. For example, it may be a battery electric vehicle (BEV), a range-extended electric vehicle (REEV), a hybrid electric vehicle (HEV), or a plug-in hybrid electric vehicle (PHEV), etc., but not limited thereto.

[0099] Optionally, the electric vehicle 1000 provided in the embodiments of the present application may be charged in a wired manner (e.g., through a charging pile) or a wireless manner (e.g., through a charging / discharging coil).

[0100] The electric vehicle 1000 provided in the embodiments of the present application includes a battery pack 500, and the battery pack 500 is suspended below the chassis 410. The battery pack 500 may include a battery pack lower box body and battery modules. The battery modules are used to store electric energy and are fixedly installed inside the battery pack lower box body. The battery pack lower box body provides support and protection for the battery modules and suspends and installs the battery modules below the vehicle chassis.

[0101] Optionally, the battery modules may be lithium-ion batteries, sodium-ion batteries, or magnesium-ion batteries, but not limited thereto. The battery modules may be in the shape of a cylinder, a flat body, a cuboid, or other shapes, etc.

[0102] Optionally, the battery pack 500 may further include a heat dissipation component for dissipating heat from the battery modules and electrical components for implementing various different functions, etc., but not limited thereto. The heat dissipation component includes, for example, a liquid cooling plate, and the electrical components include, for example, a battery management system (BMS) and a battery measurement system (BMU), etc., but not limited thereto.

[0103] As Figure 1 shown, the electric vehicle 1000 provided in the embodiments of the present application further includes an automotive air conditioner 100 and a data processing module 200. Among them, the automotive air conditioner 100 can not only condition the air in the passenger compartment of the electric vehicle 1000, but also cool down the data processing module 200.

[0104] Here, during the operation of the data processing module 200 (such as performing various data arithmetic operations), a relatively large amount of heat is generated, and an additional heat dissipation device (means) is required to cool it down. The data processing module 200 can be any processor or controller within the electric vehicle 1000 that requires heat dissipation. In the embodiments of the present application, the electric vehicle 1000 can be a vehicle with an autonomous driving function, and the data processing module 200 can be the aforementioned autonomous driving module.

[0105] Optionally, in other embodiments, the data processing module 200 can also be any controller or processor such as a battery controller, a motor controller, an electric drive controller, an inverter, a transmission controller, or a hybrid system controller. The present application does not make special limitations thereto.

[0106] Here, the passenger compartment is a cabin for people including the driver to ride in and has air conditioning requirements, such as the carriage of a passenger car or the cab of a truck, etc., but is not limited thereto.

[0107] Figure 2 It is a schematic structural diagram of an example of the vehicle air conditioner 100 provided by the embodiments of the present application. As Figure 2 shown, the vehicle air conditioner 100 includes components such as a housing 101, an evaporator 102, a distribution air duct 103, an air induction duct 104, and an adjustment air door 105. Among them, the housing 101 is a hollow box structure. For example, it can be a heating, ventilation, and air conditioning (HVAC) box. One end of the housing 101 is provided with an air inlet 101a, and the other end is provided with an air outlet 101b. The air inlet 101a is used to introduce external air into the housing 101. After heat exchange with components such as the evaporator 102, it is discharged from the air outlet 101b into the passenger compartment, thereby realizing air conditioning functions such as refrigeration, heating, air purification, ventilation, and dehumidification for the passenger compartment.

[0108] The evaporator 102 is fixedly arranged within the housing 101, and the evaporator 102 can cool the passing air. For example, the evaporator 102 can be sequentially connected in series through pipelines with an expansion valve, a condenser, and a compressor (not shown in the figure) outside the housing 101 to form a closed-loop circuit. Among them, the compressor is used to compress and drive the refrigerant. The condenser cools the high-pressure and high-temperature refrigerant transported by the compressor into a high-pressure and high-temperature liquid. The expansion valve uses the throttling effect to reduce the pressure and temperature of the refrigerant. The low-temperature and low-pressure refrigerant enters the evaporator 102 and absorbs the heat of the air to achieve refrigeration, and then returns to the compressor through the pipeline circulation again.

[0109] The air distribution duct 103 is arranged inside the housing 101 and has a duct inlet and a duct outlet. The duct inlet faces the evaporator 102 directly and is used to introduce the air-conditioned air passing through the evaporator 102. The duct outlet is far from the evaporator 102 and close to the air outlet 101b, and is used to discharge the air-conditioned air in the duct to the air outlet 101b, and finally discharge it into the passenger compartment through the air outlet 101b.

[0110] The air duct 104 is connected to the housing 101 and communicates with the air distribution duct 103. The air duct 104 is used to lead out the air-conditioned air in the air distribution duct 103 to the data processing module 200 and exchange heat with the data processing module 200, so as to realize the cooling of the data processing module 200.

[0111] For example, the air-conditioned air led out by the air duct 104 can flow through the surface of the data processing module 200 (for example, the air-conditioned air passes through the flow channel inside the module), and then can conduct convective heat exchange with the data processing module 200. Since the moisture content of the air-conditioned air cooled by the evaporator 102 is relatively low, it can also avoid generating condensate on the surface of the data processing module 200. In addition, heat dissipation fins can be added to the surface of the data processing module 200 or surface holes can be made, etc., to increase the heat exchange area, so as to achieve the purpose of enhancing the heat exchange effect. In some cases, the heat exchange effect can also be enhanced by immersing the data processing module 200 in the air duct 104.

[0112] The regulating damper 105 is rotatably arranged at the duct outlet of the air distribution duct 103 and can adjust the opening degree of the duct outlet by rotating, so as to change the amount of cold air discharged to the air outlet 101b (that is, the passenger compartment). The remaining cold air in the duct will be discharged to the data processing module 200 through the air duct 104. That is to say, by adjusting the opening degree of the duct outlet by the regulating damper 105, the air-conditioned air in the air distribution duct 103 can be distributed between the air outlet 101b and the air duct 104.

[0113] In the housing 101 of the vehicle air conditioner 100 provided by the embodiment of the present application, an air distribution duct 103 is arranged. The air inlet of the air distribution duct 103 can introduce the air-conditioning air from the evaporator 102, and the air outlet of the air distribution duct 103 can discharge the air-conditioning air in the duct to the passenger compartment through the air outlet 101b; the air guiding pipe 104 is connected to the housing 101 and communicates with the air distribution duct 103. The air guiding pipe 104 can discharge the air-conditioning air in the air distribution duct 103 to the data processing module 200 to cool the module. An adjusting damper 105 is arranged at the air outlet of the air distribution duct 103. The adjusting damper 105 can adjust the opening degree of the air outlet, can distribute the air-conditioning air in the air distribution duct 103 between the air outlet 101b and the air guiding pipe 104, and further can realize the on-demand distribution of the air-conditioning air between the passenger compartment and the data processing module 200, so that the vehicle air conditioner 100 can simultaneously meet the refrigeration requirements of the passenger compartment and the data processing module 200, and both the passenger compartment and the data processing module 200 can be effectively cooled, thus being beneficial to improving the user's driving experience.

[0114] As Figure 2 shown, by controlling the adjusting damper 105 to make the air outlet in a half-open state, at this time, part of the air-conditioning air can be discharged to the passenger compartment after passing through the air outlet and the air outlet 101b in sequence, and the remaining air-conditioning air can be discharged to the data processing module 200 through the air guiding pipe 104. At this time, the vehicle air conditioner 100 can cool the passenger compartment and the data processing module 200 simultaneously. By adjusting the opening degree of the air outlet through the adjusting damper 105, the air volume of the cold air entering the passenger compartment and the data processing module 200 can be distributed. For example, the adjusting damper 105 can be controlled to increase the opening degree of the air outlet. At this time, more cold air will be discharged to the passenger compartment and less cold air will be discharged to the data processing module 200; for another example, the adjusting damper 105 can be controlled to reduce the opening degree of the air outlet. At this time, more cold air will be discharged to the data processing module 200 and less cold air will be discharged to the passenger compartment.

[0115] As another possible implementation manner, if there is no refrigeration requirement in the passenger compartment, at this time, the adjusting damper 105 can be controlled to close the air outlet, and all the air-conditioning air in the duct will be discharged to the data processing module 200 through the air guiding pipe 104. At this time, the outside temperature may not be very high, and the evaporator 102 can be controlled not to work, and only the ambient air is used to ventilate and exchange heat with the data processing module 200.

[0116] It is worth mentioning that for the expression "air-conditioning air" in the present application, when the evaporator 102 is working, it can refer to the air flow cooled by the evaporator 102. When the evaporator 102 is not working, the "air-conditioning air" in the present application refers to the ambient air that enters the air conditioner and flows through the evaporator 102.

[0117] As Figure 2As shown, in the embodiment of the present application, the automotive air conditioner 100 further includes a blower 115, which is disposed in the housing 101 and located between the air inlet 101a and the evaporator 102.

[0118] The blower 115 serves as a power source and can form a pressure difference during operation, capable of introducing external air into the housing 101 through the air inlet 101a, and flowing through heat exchange devices such as the evaporator 102. The air after heat exchange (i.e., the air conditioner air) can be discharged from the air outlet 101b to the passenger compartment and / or discharged to the data processing module 200 through the air duct 104.

[0119] As Figure 2 shown, the air outlet 101b includes a foot blowing air outlet, a face blowing air outlet, and a defrosting air outlet. A foot blowing air door 112, a face blowing air door 113, and a defrosting air door 114 are respectively provided on the foot blowing air outlet, the face blowing air outlet, and the defrosting air outlet.

[0120] By providing the foot blowing air outlet, the face blowing air outlet, and the defrosting air outlet, the air conditioner air can be respectively guided to different positions in the passenger compartment. The foot blowing air outlet is located below the instrument panel and close to the feet of the passengers, making the lower limbs of the passengers feel comfortable; the face blowing air outlet is located on the instrument panel and opposite to the faces of the passengers, making the upper body of the passengers feel comfortable; the defrosting air outlet is close to the front windshield of the vehicle, which can prevent the glass from frosting and fogging. Moreover, a foot blowing air door 112 is provided on the foot blowing air outlet, a face blowing air door 113 is provided on the face blowing air outlet, and a defrosting air door 114 is provided on the defrosting air outlet. Each air door can be rotated and adjusted at a certain angle to control the air volume and direction of the air outlet, that is, to achieve flexible control and distribution of the cold air destination.

[0121] Optionally, the foot blowing air door 112, the face blowing air door 113, and the defrosting air door 114 can all be the currently well-known flat air doors.

[0122] Optionally, the aforementioned adjustment air door 105 can also be a flat air door.

[0123] As Figure 2 shown, in the embodiment of the present application, the automotive air conditioner 100 further includes a heating air duct 106, a heater core 107, and a temperature air door 108.

[0124] Among them, the heating air duct 106 and the air distribution air duct 103 are arranged in parallel in the housing 101. The inlet of the heating air duct 106 faces the evaporator 102 and is used to introduce the air-conditioning air passing through the evaporator 102. The outlet of the heating air duct 106 is communicated with the air outlet 101b and is used to discharge the air-conditioning air to the passenger compartment through the air outlet 101b. The heater core 107 is fixedly arranged in the heating air duct 106 and is used to heat the air-conditioning air flowing through the heating air duct 106. For example, the heater core 107 can be a positive temperature coefficient (PTC) element. In addition, the heater core 107 can also use the waste heat of the electric vehicle motor, the waste heat of the battery pack, etc. to heat the flowing air, and this application does not make special limitations.

[0125] The temperature air door 108 is usually also called a temperature adjustment air door or a cold and warm air door, etc., and is rotatably arranged in the middle of the evaporator 102 and the two air ducts. The opening degree of the inlets of the two air ducts can be adjusted through the temperature air door 108, and is used to distribute the air-conditioning air passing through the evaporator 102 between the air distribution air duct 103 and the heating air duct 106.

[0126] For example, the temperature air door 108 can completely close the inlet of the heating air duct 106. At this time, the air-conditioning air passing through the evaporator 102 is completely introduced into the air distribution air duct 103. For another example, the temperature air door 108 can simultaneously (partially) open the inlets of the air distribution air duct 103 and the heating air duct 106. At this time, part of the air-conditioning air passing through the evaporator 102 is introduced into the air distribution air duct 103, and the other part of the air-conditioning air is introduced into the heating air duct 106. For another example, the temperature air door 108 can completely close the inlet of the air distribution air duct 103. At this time, the air-conditioning air passing through the evaporator 102 is completely introduced into the heating air duct 106.

[0127] Furthermore, the heater core 107 is located on the upstream side of the air duct outlet (i.e., the adjustment air door 105). In this way, the air-conditioning air heated by the heater core 107 can still enter the air distribution air duct 103 through the air duct outlet, and then can be discharged to the data processing module 200 through the air duct 104. That is, at this time, the data processing module 200 can be heated by the warm air generated by the vehicle air conditioner 100, and the start-up heating requirement of the data processing module 200 in an extremely low temperature environment can be met. At this time, by controlling the adjustment air door 105 to adjust the opening degree of the air duct outlet, the warm air can also be distributed between the passenger compartment and the data processing module 200.

[0128] In summary, in the embodiments of the present application, through the above settings related to the heating air duct 106, the heater core 107, the temperature air door 108, etc., and combined with the flexible switching and matching of the working positions of the regulating air door 105 and the temperature air door 108, the vehicle air conditioner 100 has more usage functions. At this time, different working modes of the air conditioner can be entered by controlling the working positions of the regulating air door 105 and the temperature air door 108, so that the vehicle air conditioner 100 can also meet the usage requirements in more scenarios such as passenger compartment heating, passenger compartment dehumidification, and heating of the data processing module 200. Thereby, the usage performance and product competitiveness of the vehicle air conditioner 100 are improved.

[0129] Similarly, the expression "air conditioner air" in the present application may also refer to the air flow heated by the heater core 107, or the air flow that has been cooled by the evaporator 102 and then heated by the heater core 107.

[0130] As Figure 2 shown, in the embodiments of the present application, the air duct outlet is provided on the partition wall between the air distribution air duct 103 and the heating air duct 106. Through the above settings, the air duct outlet of the air distribution air duct 103 can face the heating air duct 106, and the warm air in the heating air duct 106 can more easily enter the air distribution air duct 103. Thereby, the internal structure design and control logic of the air conditioner can be simplified. At this time, by controlling the working positions of the regulating air door 105 and the temperature air door 108, heating or cooling of the data processing module 200 can be achieved, and the switching of the working modes of the vehicle air conditioner 100 is more simple and efficient.

[0131] Furthermore, the front end of the air guiding pipe 104 can be inserted into the interior of the housing 101. At this time, the pipe wall of the air guiding pipe 104 can form the side wall of the air distribution air duct 103 facing the air outlet 101b, and the air duct outlet of the air distribution air duct 103 can be opposite to the port of the air guiding pipe 104, facilitating the air conditioner air to enter the interior of the air guiding pipe 104 through the air duct outlet of the air distribution air duct 103.

[0132] As Figure 2 shown, the vehicle air conditioner 100 provided in the embodiments of the present application further includes an exhaust air duct 109. The exhaust air duct 109 is communicated with the air guiding pipe 104 and is used to discharge the air conditioner air that has exchanged heat with the data processing module 200 into the environment. By providing the exhaust air duct 109, it is convenient to discharge the heat-exchanged air into the atmospheric environment.

[0133] As Figure 2As shown, the automobile air conditioner 100 provided in the embodiment of the present application also includes a return air duct 110 and an outlet damper 111. The return air duct 110 is connected to the induced air duct 104, and is used to discharge the conditioned air after heat exchange with the data processing module 200 into the passenger compartment. The outlet damper 111 is used to distribute the conditioned air after heat exchange with the data processing module 200 between the exhaust duct 109 and the return air duct 110.

[0134] By setting the return air duct 110, the air conditioning wind after heat exchange with the data processing module 200 can be discharged into the passenger compartment. At this time, the heat generated by the data processing module 200 when it is working can be used to heat the passenger compartment. When the passenger compartment needs to heat, the heat of the data processing module 200 can be recovered. The heat of the data processing module 200 can be directly returned to the passenger compartment for direct heating, reducing the heat dissipation loss of the pipeline, which can improve the energy efficiency of the whole vehicle and increase the cruising range in low temperature environments. By setting the outlet damper 111 to distribute the air conditioning wind after heat exchange with the data processing module 200 between the exhaust duct 109 and the return air duct 110, the air conditioning wind after heat exchange can be discharged into the environment or introduced into the passenger compartment according to the actual situation, thereby making the use of the automobile air conditioner 100 provided in the embodiment of the present application more flexible and more adaptable, and able to meet the use needs in more scenarios.

[0135] like Figure 2 As shown, in an embodiment of the present application, the exhaust duct 109 and the return air duct 110 can be connected in parallel, and both are connected to the induced air duct 104 through the connecting pipe 116, and the outlet air door 111 is rotatably arranged at the connection between the exhaust duct 109 and the return air duct 110, thereby simplifying the design and facilitating the setting of the outlet air door 111.

[0136] Furthermore, if Figure 2 As shown, the air duct 104 is connected to the shell 101 through the first connection port 101c, and the return air duct 110 is connected to the shell 101 through the second connection port 101d. The second connection port 101d is located between the first connection port 101c and the air outlet 101b.

[0137] By connecting the return air duct 110 to the shell 101 and locating it on the downstream side of the air duct 104, the heat destination can be flexibly controlled and distributed based on the existing face-blowing damper, foot-blowing damper, defrost damper and other structures of the air-conditioning box, which is conducive to simplifying the overall structure and reducing implementation costs.

[0138] Figure 3 FIG. 1 is a schematic diagram of another example of the structure of the automotive air conditioner 100 provided in the embodiment of the present application. Figure 3 As shown above, Figure 2Compared with the embodiments shown, the return air duct 110 in this embodiment is not connected to the housing 101. When there is a heating or dehumidification requirement in the passenger compartment and there is heat in the data processing module 200 that can be recycled, the air heated and raised in temperature by the data processing module 200 does not pass through the air conditioning box but directly returns to the passenger compartment to directly heat the passenger compartment. Since the pipeline connection can be reduced, this heat dissipation solution that does not pass through the air conditioning box can reduce the heat dissipation loss of the pipeline.

[0139] As Figure 1 shown, in the embodiment of the present application, the electric vehicle 1000 further includes a control device 300, which is communicatively connected to the vehicle air conditioner 100 and can control the vehicle air conditioner 100. Here, the control device 300 can be various controllers or processors. For example, the control device 300 can be a microcontroller unit (MCU), an electronic control unit (ECU), or a programmable logic controller (PLC), etc., but is not limited thereto.

[0140] The control device 300 is also electrically connected to the data processing module 200 and the air conditioner controller in the passenger compartment, etc., and can control the vehicle air conditioner 100 to operate according to the requirements of the passenger compartment and the data processing module 200. Here, the requirements of the passenger compartment can include refrigeration, heating, ventilation, or dehumidification, etc., and the requirements of the data processing module 200 include refrigeration or heating.

[0141] Figure 4 is a schematic flow chart of the control device 300 controlling the vehicle air conditioner 100. As Figure 4 shown, in the embodiment of the present application, the control device 300 determines the working mode of the vehicle air conditioner 100 according to the requirements of the passenger compartment and the data processing module 200, and executes this working mode. Specifically, the control device 300 can determine the requirements of the passenger compartment according to the control instructions from the passengers in the passenger compartment, and determine the requirements of the data processing module 200 through the temperature of the temperature sensor set on the data processing module 200. For example, when it is determined that the temperature of the data processing module 200 is higher than the preset upper limit value, it is determined that the data processing module 200 needs to be refrigerated, and when it is determined that the temperature of the data processing module 200 is lower than the preset lower limit value, it is determined that the data processing module 200 needs to be heated (started).

[0142] In the embodiment of the present application, the vehicle air conditioner 100 includes a total of 7 working modes, which are respectively Figure 4Modes 1 to 7 therein. Among them, Mode 1 is to cool the passenger compartment and the data processing module 200 simultaneously, Mode 2 is to cool the data processing module 200 alone, Mode 3 is to weakly dehumidify the passenger compartment, Mode 4 is to strongly dehumidify the passenger compartment, Mode 5 is to heat the passenger compartment through the data processing module 200, Mode 6 is to heat the passenger compartment jointly by the warm air core 107 and the data processing module 200; Mode 7 is to heat the passenger compartment and the data processing module 200 simultaneously. The control device 300 can control the vehicle air conditioner 100 according to a preset control method so that the vehicle air conditioner 100 enters any one of the working modes. The following introduces the above 7 working modes of the vehicle air conditioner 100 respectively in conjunction with the accompanying drawings.

[0143] Mode 1: Cool the passenger compartment and the data processing module 200 simultaneously.

[0144] Figure 5 is a schematic structural diagram of the vehicle air conditioner 100 in the working state of Mode 1. As Figure 5 shown, in a high-temperature environment (for example, the ambient temperature ≥ T1), both the passenger compartment and the data processing module 200 have a refrigeration requirement. The data processing module 200 can directly divert part of the cold air for refrigeration. At this time, the control device 300 can control the vehicle air conditioner 100 according to the following control method:

[0145] When both the passenger compartment and the data processing module 200 have a refrigeration requirement, control the evaporator 102 to enter the working state; control the regulating air door 105 to open the air duct outlet so that the vehicle air conditioner 100 cools the passenger compartment and the data processing module 200 simultaneously.

[0146] Specifically, the control device 300 can control the evaporator 102 to enter the working state and control the warm air core 107 to be in the non-working state; by adjusting the position of the temperature air door 108, the cold air from the evaporator 102 does not pass through the warm air core 107 and all enters the air distribution duct 103; by controlling the position of the regulating air door 105, part of the cold air enters the passenger compartment through the face air outlet for refrigeration, and the other part cools the data processing module 200 through the air duct 104; by adjusting the outlet air door 111, all the hot air heated and raised in temperature by the data processing module 200 is discharged to the atmospheric environment through the exhaust duct 109.

[0147] As a possible implementation manner, when the passenger compartment is in the refrigeration state but there is a sudden temperature increase requirement, such as raising the target air outlet temperature, by adjusting the outlet air door 111, part of the hot air heated and raised in temperature by the data processing module 200 returns to the air conditioner box through the return air duct 110 to quickly raise the temperature, and the other part is discharged to the atmospheric environment through the exhaust duct 109.

[0148] Mode 2: Cool the data processing module 200 alone.

[0149] Figure 6 It is a schematic structural diagram of the automotive air conditioner 100 in the working state of Mode 2. As Figure 6 shown, in a medium-temperature environment (for example, T2 ≤ ambient temperature < T1), there is no demand in the passenger compartment, and the data processing module 200 has a refrigeration demand. At this time, the control device 300 can control the automotive air conditioner 100 according to the following control method:

[0150] When the data processing module 200 has a refrigeration demand and there is no refrigeration demand in the passenger compartment, the control regulating air door 105 closes the air duct outlet so that the automotive air conditioner cools the data processing module 200 alone. If the heat load of the data processing module 200 is not high, the control device 300 can control the evaporator 102 not to work and can directly ventilate for cooling. The control positions of each air door are as Figure 6 shown.

[0151] Specifically, at this time, the control device 300 controls the heater core 107 to be in a non-working state, and by adjusting the position of the temperature air door 108, the air coming out of the evaporator 102 does not pass through the heater core 107 and all enters the air distribution duct 103; if the data processing module 200 has a strong refrigeration demand, the evaporator 102 can be controlled to be in a working state. If the refrigeration demand of the data processing module 200 is not high and the heat dissipation demand of the data processing module 200 can be met only by introducing ambient air, the evaporator 102 can be controlled to be in a non-working state; by controlling the position of the regulating air door 105, the air duct outlet of the air distribution duct 103 is completely closed. At this time, the air coming out of the evaporator 102 cools the data processing module 200 through the air induction pipe 104; the control outlet air door 111 closes the return air pipe 110 so that the hot air heated and raised in temperature after passing through the data processing module 200 all leads to the atmospheric environment through the exhaust pipe 109.

[0152] Mode 3: Weak dehumidification of the passenger compartment.

[0153] Figure 7 It is a schematic structural diagram of the automotive air conditioner 100 in the working state of Mode 3. As Figure 7 shown, in a medium-temperature environment (for example, T2 ≤ ambient temperature < T1), there is a dehumidification demand in the passenger compartment and the dehumidification demand is not high. At this time, the control device 300 can control the automotive air conditioner 100 according to the following control method:

[0154] When the passenger compartment has a weak dehumidification requirement (which can be determined specifically through an instruction from the passenger compartment), control the evaporator 102 to enter the working state; control the temperature air door 108 to close the heating air duct 106; control the regulating air door 105 to close the air duct outlet; control the outlet air door 111 to open the return air duct 110, so that at least part of the air-conditioning air heated by the data processing module 200 is discharged into the passenger compartment.

[0155] Specifically, when the passenger compartment has a dehumidification requirement and the initial requirement is not high, the control device 300 can control the evaporator 102 to work at a lower load (power), and control the temperature air door 108 to close the inlet of the heating air duct 106 and control the regulating air door 105 to close the air duct outlet of the air distribution air duct 103. At this time, all the cold air from the evaporator 102 enters the air distribution air duct 103 and all cools the data processing module 200 through the air guiding duct 104. The control device 300 further controls the outlet air door 111 to close the exhaust air duct 109, so that all the air heated and raised in temperature by the data processing module 200 returns to the passenger compartment. In addition, if the air volume is too large, the position of the outlet air door 111 can also be controlled so that part of the air-conditioning air heated and raised in temperature by the data processing module 200 returns to the passenger compartment and part leads to the atmospheric environment.

[0156] Mode 4: Strong dehumidification of the passenger compartment.

[0157] Figure 8 It is a schematic structural diagram of the automotive air conditioner 100 in the working state of Mode 4. As Figure 8 shown, in a medium-temperature environment (for example, T2 ≤ ambient temperature < T1), when the passenger compartment has a dehumidification requirement and the dehumidification requirement is high, the control device 300 can control the automotive air conditioner 100 according to the following control method:

[0158] When the passenger compartment has a strong dehumidification requirement (which can be determined specifically through an instruction from the passenger compartment), control both the evaporator 102 and the heater core 107 to enter the working state; control the temperature air door 108 to open both the air distribution air duct 103 and the heating air duct 106 at the same time; control the regulating air door 105 to close the air duct outlet of the air distribution air duct 103; control the outlet air door 111 to close the exhaust air duct 109, so that all the air-conditioning air heated by the data processing module 200 is discharged into the passenger compartment.

[0159] Specifically, when there is a dehumidification requirement in the passenger compartment and the dehumidification requirement is high, the control device 300 can control the evaporator 102 to start working at a high load (power), control the heater core 107 to start working, and control the temperature air door 108 to open the air distribution duct 103 and the heating duct 106 simultaneously, and control the regulating air door 105 to close the duct outlet of the air distribution duct 103. At this time, a part of the cold air from the evaporator 102 is heated by the heater core 107 in the heating duct 106 and then enters the passenger compartment through the defrost air door (to avoid discomfort caused by low outlet air temperature); another part of the cold air is discharged to the data processing module 200 through the air distribution duct 103 and the air guide pipe 104; control the position of the outlet air door 111 so that all the air-conditioning air heated and raised in temperature by the data processing module 200 returns to the passenger compartment.

[0160] As another possible implementation, if it can be ensured that the outlet air temperature is not too low, the heater core 107 can also be controlled not to work, and the cold air from the evaporator 102 passes through the heating duct 106 but enters the passenger compartment directly without being heated.

[0161] Mode 5: Heat the passenger compartment through the data processing module 200.

[0162] Figure 9 It is a schematic structural diagram of the automotive air conditioner 100 in the working state of Mode 5. As Figure 9 shown, in a low-temperature environment (for example, T3 ≤ ambient temperature < T2), if there is a heating requirement in the passenger compartment and the data processing module 200 has a heat dissipation requirement at this time, the heat of the data processing module 200 can be recovered to achieve heating of the passenger compartment. At this time, the control device 300 can control the automotive air conditioner 100 according to the following control method:

[0163] When there is a heating requirement in the passenger compartment (the heating requirement is weak) and the data processing module 200 has a heat dissipation requirement, control the temperature air door 108 to close the heating duct 106; control the regulating air door 105 to close the duct outlet; control the outlet air door 111 to open the return air pipe 110 so that at least part of the air-conditioning air heated by the data processing module 200 is discharged into the passenger compartment.

[0164] Specifically, when there is a heating requirement in the passenger compartment, the passenger compartment can be heated by the heat generated when the data processing module 200 works. The control device 300 can control the evaporator 102 not to work, control the temperature air door 108 to close the heating duct 106, and control the regulating air door 105 to close the duct outlet so that all the air passing through the evaporator 102 is discharged to the data processing module 200 through the air guide pipe 104. By controlling the position of the outlet air door 111, all the heated and raised air returns to the housing 101 through the return air pipe 110, or part enters the housing 101 and part enters the atmosphere through the exhaust pipe 109.

[0165] Mode 6: The passenger compartment is heated jointly by the data processing module 200 and the heater core 107.

[0166] Figure 10 It is a schematic structural diagram of the automotive air conditioner 100 in the working state of Mode 6. As Figure 10 shown, in a low-temperature environment (for example, T3 ≤ ambient temperature < T2), if there is a heating demand in the passenger compartment at this time, and using the data processing module 200 alone cannot meet the heating demand of the passenger compartment, the heater core 107 can be jointly used to heat the passenger compartment at this time. At this time, the control device 300 can control the automotive air conditioner 100 according to the following control method:

[0167] When there is a heating demand (strong heating demand) in the passenger compartment and the data processing module 200 has a heat dissipation demand, control the heater core 107 to enter the working state; control the temperature damper 108 to open the air distribution duct 103 and the heating duct 106 at the same time; control the regulating damper 105 to close the duct outlet; control the outlet damper 111 to close the exhaust duct 109 so that all the air-conditioned air heated by the data processing module 200 is discharged into the passenger compartment.

[0168] Specifically, when there is a strong heating demand in the passenger compartment, the passenger compartment can be heated jointly by the data processing module 200 and the heater core 107. At this time, the control device 300 can control the evaporator 102 not to work, control the heater core 107 to enter the working state, control the temperature damper 108 to open the air distribution duct 103 and the heating duct 106 at the same time, and control the regulating damper 105 to close the duct outlet of the air distribution duct 103. The air passing through the evaporator 102 is partially discharged to the data processing module 200 through the air guide duct 104, and partially enters the passenger compartment through the foot blowing damper after being heated by the heater core 107. By controlling the position of the outlet damper 111, all the air heated and raised in temperature by the data processing module 200 is returned to the housing 101 through the return duct 110.

[0169] Mode 7: Heat the passenger compartment and the data processing module 200 simultaneously.

[0170] Figure 11 It is a schematic structural diagram of the automotive air conditioner 100 in the working state of Mode 7. As Figure 11 shown, in an extremely low-temperature environment (for example, ambient temperature < T3), if there is a heating demand in the passenger compartment and the data processing module 200 has a start heating demand, the passenger compartment and the data processing module 200 can be heated simultaneously by the automotive air conditioner 100 at this time. The control device 300 can control the automotive air conditioner 100 according to the following control method:

[0171] When both the passenger compartment and the data processing module 200 have a heating requirement, control the heater core 107 to enter the working state; control the temperature air door 108 to close the air distribution duct 103; control the regulating air door 105 to open the air duct outlet of the air distribution duct 103, so that the vehicle air conditioner heats the passenger compartment and the data processing module 200 simultaneously.

[0172] Specifically, in an extremely low temperature environment, the passenger compartment and the data processing module 200 may simultaneously have a heating requirement. At this time, the control device 300 can control the evaporator 102 not to work and control the heater core 107 to be in the working state; control the temperature air door 108 to close the air distribution duct 103 so that all the air at the outlet of the evaporator 102 passes through the heater core 107 for heating. Control the regulating air door 105 to open the air duct outlet of the air distribution duct 103, so that a part of the hot air from the heater core 107 heats the passenger compartment through the foot air door, and the other part enters the air guide pipe 104 through the air distribution duct 103 to heat the data processing module 200. If the temperature of the air from the outlet of the data processing module 200 is relatively low (such as lower than the ambient temperature), it is directly discharged into the atmosphere through the exhaust pipe 109. If the temperature of the air from the outlet of the data processing module 200 is relatively high (such as higher than the ambient temperature), control the outlet air door 111 so that the air from the module passes back into the housing 101 through the return air pipe 110.
