Description

Technical Field

[0001] The present invention relates to a system integrating a vehicle air conditioner and a cooling or heating device, and a control method thereof.

Background Art

[0002] Conventional automotive centralized air conditioning systems consist of an intake pipe, a cooling / heating system, and a blower pipe (see Figures 1 and 2). The intake pipe has two intake ports: one intake port 1a for drawing in outside air, and the other intake port 2a for drawing in circulating air from inside the vehicle. The outlet of the intake pipe is connected to the cooling / heating system, and the outlet of the cooling / heating system is connected to the blower duct. The cooling / heating system consists of a high-output blower fan 3a, an evaporator 4a, a compressor, a throttle valve, a condenser, and a heat dissipation fan. After cooling the air in the intake pipe, the cooling / heating system blows it into the vehicle through the blower duct. Multiple outlet ducts 5a are installed at the end of the blower duct, and the openings of each outlet duct 5a are located in different areas of the vehicle. A valve switch for adjusting the airflow is provided at the end of the outlet duct. Conventional automotive air conditioning ventilation systems have the following drawbacks: 1. High-power blower fans are too large and installed in the engine compartment, severely restricting the engine compartment's spatial layout; 2. After the high-power blower fan delivers cool / warm air, the process of transmission through the ventilation duct, especially over long distances to the rear seat area, results in significant airflow loss, reducing the energy efficiency of the ventilation system; 3. In centralized ventilation systems, the blower fan directly delivers cool / warm air to the end of the vents, blowing it onto passengers, causing rapid changes in passenger body temperature and reducing comfort; 4. In centralized ventilation systems, the airflow volume at each vent cannot be individually controlled, and passengers cannot set the fan speed according to their individual needs. Airflow loss occurs because valves are installed at each vent, and the airflow is adjusted by opening and closing them; 5. In centralized ventilation systems, the blower fan directly delivers cool air to passengers from the end of the vents, causing rapid changes in passenger body temperature and reducing comfort. 6. Conventional automobiles introduce fresh air into the cabin using the inertia of the vehicle while it is in motion. However, uncontrolled cold or warm air from the outside affects the effectiveness of the cabin's air conditioning, increasing energy consumption and compromising passenger comfort.

[0003] Furthermore, with the development of new energy electric vehicles, the three core components of electric vehicles—the drive motor, power battery, and drive control system—generate the most heat during operation, making their heat dissipation systems particularly important. Traditional manufacturing methods involve liquid cooling, specifically the installation of liquid cooling pipes to cool the drive motor and drive control system. However, the installation of liquid cooling pipes presents sealing problems, complicates the product structure, increases manufacturing costs, and reduces integration density. Research and experiments have revealed that the drive motor generates the most significant heat, requiring liquid cooling to quickly remove operating heat. On the other hand, the power battery and drive control system generate relatively little heat, so air cooling can meet their heat dissipation requirements. This mitigates various challenges associated with the installation of liquid cooling pipes, simplifies the structure, and reduces manufacturing costs.

[0004] Thirdly, in extremely cold environments, in addition to heat dissipation issues, it is also necessary to consider that the drive motor, power battery, and drive control system of an electric vehicle must be able to start and operate normally within an appropriate operating temperature range.

[0005] Therefore, a redesign of the system is necessary to effectively control the operating temperature of the power battery and the drive control system. [Overview of the Initiative] [Problems that the invention aims to solve]

[0006] This invention provides a system and control method that integrates vehicle air conditioning and cooling or heating devices, solving the technical problems of existing electric vehicle power battery and drive control system operating temperature control systems, which are structurally complex, lack integration, and are costly. [Means for solving the problem]

[0007] The technical solution of the present invention is as follows:

[0008] This is a vehicle air conditioning and cooling or heating system integrated into a single system, including a power vent system. This power vent system consists of an intake pipe, a cooling / heating system, and a blower pipe, with the intake pipe having an outside air inlet and an internal air circulation inlet. The outlet of the intake pipe is connected to the cooling / heating system, which includes a high-power blower and a heat exchanger. The outlet of the cooling / heating system is connected to a blower duct, and multiple vents are located at the end of the blower duct. End-end ventilation systems are installed at the openings of these vents, and these end-end ventilation systems incorporate a low-power blower fan and a blower fan. The outlet of the heating system is connected to a blower duct, and multiple outlets are located at the end of the blower duct. End-end ventilation systems are located at the pipe openings of these outlets, and these end-end ventilation systems include a low-power blower fan and a low-speed fan, with the low-power blower installed at the end of the outlet pipe and the low-speed fan installed near the pipe opening of the outlet pipe. The end-of-vehicle ventilation system mixes the low / high temperature airflow output from the cooling / heating system with the ambient temperature airflow inside the vehicle and blows it to the user's position inside the vehicle.

[0009] Its distinguishing feature is the inclusion of a cooling or heating device. The cooling or heating device includes multiple third pipelines installed at the end of the air duct, each containing a cooling fan. The cooling fans use the low / high temperature airflow output from the cooling / heating system to dissipate heat or heat the vehicle's power battery and / or drive control system.

[0010] The aforementioned terminal ventilation system is controlled by a central control system, and the cooling fans of the cooling or heating devices are also controlled by the central control system. A temperature sensor is installed in the power battery and / or drive control system, which measures the operating temperature of the power battery and / or drive control system and transmits it to the central control system. Based on the operating temperature of the power battery and / or drive control system, the central control system uses the cooling fan to cool or heat the vehicle's power battery and / or drive control system using the low / high temperature airflow output from the cooling / heating system.

[0011] The above-mentioned integrated vehicle air conditioning and cooling or heating system also includes a ventilation system. The ventilation system consists of a first pipeline and a second pipeline. An intake fan is installed in the first pipeline. The intake fan actively draws fresh air into the vehicle cabin from the inlet of the first pipeline. An exhaust fan is installed in the second pipeline, and the inlet of the second pipeline is connected to the vehicle cabin. The exhaust fan expels the dirty air from the vehicle cabin to the outside from the outlet of the second pipeline.

[0012] The second pipeline described above has two exhaust fans installed, and both exhaust fans are positioned close to both ends of the second pipeline.

[0013] Both the intake and exhaust fans mentioned above utilize high-speed, compact fans designed for ductwork.

[0014] The end-stage ventilation system described above also includes a ventilation control unit, which controls the operation of the low-power and low-speed fans within the end-stage ventilation system. A central control system manages the operation of each ventilation control unit.

[0015] Both the intake and exhaust fans mentioned above are controlled by a central control system. An air conditioning device is also installed in the first piping, which includes a filter, a cooler, and a humidifier. An outside air temperature sensor and an outside air valve are installed at the fresh air inlet end of the first piping. The outside air temperature sensor transmits the detected temperature signal to the central control system, which controls the operation of the outside air valve and the air conditioning device.

[0016] The above cooling / heating system further includes a compressor, throttle valve, cooling fan, and radiator, and the heat exchanger is an evaporator.

[0017] The above-mentioned power battery supplies power to the vehicle's drive motor, and the drive control system controls the operation of the vehicle's drive motor.

[0018] A control method for a system integrating vehicle air conditioning and cooling or heating devices. This system employs the aforementioned system integrating vehicle air conditioning and cooling or heating devices, and its features are as follows:

[0019] A temperature sensor detects the temperature of the power battery or drive control system. If the temperature is above or below the effective operating temperature range of the power battery or drive control system, the temperature sensor transmits a signal to the central control system. The central control system automatically controls the cooling fan, directing cool or warm air from the cooling / heating system towards the power battery or drive control system to dissipate heat or heat the system. When the temperature of the power battery or drive control system reaches the set operating temperature range, the central control system automatically stops the cooling fan or reduces its speed. This process is repeated.

[0020] The present invention has the following advantages compared to the prior art:

[0021] 1. The present invention integrates a vehicle air conditioner with a cooling or heating device and employs an air-cooled design for the power battery and / or drive control system. The cooling or heating device is reintegrated into the vehicle air conditioner system, and the cooling or heating device has multiple third pipelines installed at the end of the air supply pipe, with a cooling fan installed in each third pipeline. The cooling fan uses the low / high temperature airflow output from the cooling / heating system to dissipate heat or heat the power battery and / or drive control system on the vehicle. This simplifies the structure, reduces manufacturing costs, and achieves high integration.

[0022] 2. The present invention adds a power air outlet system to the power battery or drive control system and installs multiple third pipelines at the end of the air outlet pipe. A cooling fan is installed in each third pipeline, and the temperature of the battery or drive system is simultaneously sensed. Through centralized automatic control by a central control system, the energy of the vehicle air conditioning and cooling system is used and centrally managed, thereby achieving energy savings for the vehicle.

[0023] 3. The control method of the present invention can effectively control the operating temperature of the power battery or the drive control system and adapt to different working environments such as severe cold or high temperature. Thereby, it extends the lifespan, reduces the occurrence of failures, and has the characteristics of simple control and high reliability.

Modes for Carrying Out the Invention

[0026] To make the purpose, technical solution and advantages of the embodiments of the present invention clearer, hereinafter, while referring to the drawings in the embodiments of the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described. It should be noted that the embodiments described here are only some embodiments of the present invention and do not represent all embodiments. Based on this embodiment, all other embodiments obtained by those skilled in the art without creative labor are included in the protection scope of the present invention.

Embodiment

[0027] As shown in Figures 3, 4, 5, 6, and 7, this embodiment provides a system that integrates a vehicle air conditioning system with a cooling or heating system. This system includes a power vent system 100 and is configured as follows:

[0028] The powered air vent system 100 consists of an intake pipe 1, a cooling / heating system 2, and a blower pipe 3. The intake pipe 1 is provided with an outside air inlet 11a and an internal circulation inlet 11b, and the outlet of the intake pipe 1 is connected to the cooling / heating system 2. The cooling / heating system 2 includes a high-power blower 21 and a heat exchanger 22. The outlet of the cooling / heating system 2 is connected to the blower pipe 3, and multiple discharge pipes 31 are installed at the end of the blower pipe 3. An end-of-vehicle ventilation system 4 is provided at the opening of the discharge pipes 31. The end-of-vehicle ventilation system 4 includes a low-power blower 41 and a low-speed fan 42. The low-power blower 41 is installed at the end of the discharge pipe 31, and the low-speed fan 42 is installed near the opening of the discharge pipe 31. The end-of-vehicle ventilation system 4 mixes the low-temperature / high-temperature airflow output from the cooling / heating system 2 with the ambient temperature airflow inside the room, and then blows the air towards the position of the user inside the vehicle. Its features include the inclusion of a cooling or heating device 7, which comprises a plurality of third pipelines 71 installed at the end of the air supply pipe 3, with a cooling fan 72 installed inside each third pipeline 71, and the cooling fan 72 uses the low / high temperature airflow output from the cooling / heating system 2 to cool or heat the vehicle's power battery and / or drive control system.

[0029] As shown in Figure 4, the cooling / heating system 2 further includes a compressor, a throttle valve, a condenser, and a heat dissipation fan.

[0030] The aforementioned terminal ventilation system 4 is controlled by the central control system 6, and the cooling fan 72 of the cooling or heating device 7 is also controlled by the central control system 6. A temperature sensor 73 is installed in the power battery and / or drive control system, and the temperature sensor 73 measures the operating temperature of the power battery and / or drive control system and transmits it to the central control system 6. Based on the operating temperature of the power battery and / or drive control system, the central control system 6 uses the cooling fan 72 to cool or heat the power battery and / or drive control system on the vehicle using the low / high temperature airflow output from the cooling / heating system 2.

[0031] Advantages of the present invention: 1. Integrates the vehicle air conditioner with a cooling or heating device and adopts an air-cooled design for the power battery and / or drive control system. The cooling or heating device is reintegrated into the vehicle air conditioner system, and the cooling or heating device has multiple third pipelines installed at the end of the air duct, with a cooling fan installed in each third pipeline. The cooling fan uses the low / high temperature airflow output from the cooling / heating system to dissipate heat or heat the power battery and / or drive control system on the vehicle. This simplifies the structure, reduces manufacturing costs, and achieves high integration. 2. The present invention adds a power air outlet system at the location of the power battery or drive control system and installs multiple third pipelines at the end of the air duct. A cooling fan is installed in each third pipeline, and simultaneously senses the temperature of the battery or drive system, and centralized automatic control is performed through the central control system 6. This enables comprehensive use and centralized management of the energy of the vehicle air conditioning and cooling system, achieving energy savings for the vehicle.

[0032] As shown in Figure 5, the power vent system 100 is equipped with a ventilation device 5, which consists of a first pipeline 51 and a second pipeline 53. An intake fan 52 is installed inside the first pipeline 51, and the intake fan 52 actively draws fresh air into the vehicle cabin from the inlet of the first pipeline 51. An exhaust fan 54 is installed inside the second pipeline 53, and the inlet of the second pipeline 53 is in communication with the vehicle cabin. The exhaust fan 54 discharges the dirty air from the vehicle cabin to the outside from the outlet of the second pipeline 53. Fans are installed inside the first pipeline 51 and the second pipeline 53, located at the front and rear ends of the ducts, respectively. The two fans form a siphon effect within the ducts, generating negative pressure and improving the airflow efficiency of the fan system. The intake fan 52 and the exhaust fan 54 can be centrally controlled by the central air conditioning control system 6, effectively managing the energy consumption of the vehicle air conditioning system and improving passenger comfort.

[0033] Both the intake fan 52 and the exhaust fan 54 described above employ high-speed, compact fans designed for ducts.

[0034] The aforementioned end-effector ventilation system 4 is controlled by the central control system 6.

[0035] The exhaust fan 54 described above is controlled by the central control system 6.

[0036] The aforementioned low-power blower 41 is positioned diagonally behind the low-speed fan 42. The high-speed, low-power blower 41 directs the low-temperature / high-temperature airflow from the cooling / heating system 2 to the rear of the low-speed fan 42, which then mixes the low-temperature / high-temperature airflow with the ambient temperature airflow before blowing it to the passenger seats. By mixing the low-speed fan 42 with the low-temperature / high-temperature airflow, both the air temperature and wind speed become more comfortable.

[0037] The terminal ventilation system 4 also includes a ventilation control unit 43, which controls the operation of the high-speed, low-power blower 41 and low-speed fan 42 within the terminal ventilation system 4. The central control system 6 manages the operation of each ventilation control unit 43. Users in different locations can set the airflow speed of the terminal ventilation system 4 according to their individual needs, better meeting the diverse needs of users and improving the user experience. The ventilation control unit 43 is actually an integrated motor controller and can simultaneously control the operation of both the low-power blower 41 and the low-speed fan 42. The central control system 6 is the central control system for air conditioning, and a detailed explanation is omitted here.

[0038] The end-level ventilation system 4 described above is further equipped with an infrared / temperature sensing system 44. The infrared / temperature sensing system 44 senses the user's position and transmits a sensing signal to the central control system 6. The central control system 6 controls the operation of each ventilation control unit 43 based on the sensing signal. The central control system 6 can individually control the operation of each end-level ventilation system 4.

[0039] The airflow angles of both the low-power blower 41 and the low-speed fan 42 described above are adjustable. For example, the airflow angle can be adjusted within a range of 10 to 90 degrees.

[0040] The user location status described above includes detection of the presence or absence of a user, temperature detection, and sleep detection.

[0041] The infrared / temperature sensing system 44 identifies whether a user is in the seat, whether the user is asleep, and whether the user's body temperature is too high or too low. The system then automatically adjusts the temperature and fan speed to the optimal level for each user location via a centralized control system. This improves user comfort and enhances energy efficiency.

[0042] The intake fan 52 and exhaust fan 54 are controlled by a central control system 6. An air conditioning device 55 is installed in the first pipeline 51, and this air conditioning device 55 includes a filter, a cooler, and a humidifier. An outside air temperature sensor 57 and an outside air valve 56 are installed on the fresh air inlet side of the first pipeline 51. The outside air temperature sensor 57 transmits the detected temperature signal to the central control system 6, and the central control system 6 controls the operation of the outside air valve 56 and the air conditioning device 55. The central control system 6 controls the opening and closing of the outside air valve 56, thereby adjusting the amount of outside air flowing in.

[0043] Improvements to the power ventilation system enhance the energy efficiency of vehicles and improve passenger (i.e., user) comfort. The benefits are as follows:

[0044] 1. In automotive applications, by eliminating the high-power centralized cooling fan inside the engine compartment and instead adding a high-power consumption fan 21 inside the centralized cooling duct, the spatial layout of the engine compartment can be made more effective, improving the rationality of the engine compartment spatial design.

[0045] 2. In automotive applications, the air blown out by the high-power blower 21 is supplemented by a high-speed, low-power blower fan added to the duct at the end of the air outlet. This creates negative pressure within the duct due to the siphon effect, reducing the attenuation of the airflow of cold (or hot) air within the duct and improving the energy efficiency of the fan system.

[0046] 3. In automotive applications, each outlet pipe 31 is equipped with an independent airflow control unit 43 to individually control the low-power blower 41 of each outlet pipe 31. At the same time, a central control system 6 is located on the center console, which can individually control the rotation speed of the low-power blower 41 of each outlet pipe 31.

[0047] 4. By installing a low-power blower fan 41 in each outlet pipe 31, occupants in different positions can set the rotation speed of each blower fan 41 according to their individual needs, better meeting the diverse demands of occupants and improving comfort.

[0048] 5. An infrared / temperature sensing system 44 is added to each air outlet 31 to sense whether there is a person in the seat, whether they are sleeping, and whether their body temperature is excessively high or low. This allows the central control system 6 to automatically adjust the temperature and airflow to the optimal level for each person's position, improving comfort.

[0049] 6. A low-speed fan 42 is added to each outlet pipe 31, and by mixing the surrounding air with the cool (or warm) air sent by the low-power blower 41 and blowing it onto people, a natural breeze is reproduced and comfort is improved.

[0050] 7. The new air conditioning ventilation system achieves constant airflow control, reducing the risk of reduced airflow due to increased duct static pressure caused by factors such as filter clogging, and improving the perceived effectiveness of air conditioning and cooling. [Examples]

[0051] As shown in Figures 6 and 7, this is a control method for a system integrating vehicle air conditioning and a cooling or heating device, and the system employs the system integrating vehicle air conditioning and a cooling or heating device described in Embodiment 1. Its features are as follows: A temperature sensor 73 senses the temperature of the power battery or drive control system, and if the temperature is above or below the effective operating temperature range of the power battery or drive control system, the temperature sensor transmits a signal to the central control system 6. The central control system 6 automatically controls the cooling fan 72 to blow the cool or warm air output by the cooling / heating system 2 toward the power battery or drive control system, thereby dissipating heat or heating the power battery or drive control system. When the temperature of the power battery or drive control system reaches the set safe operating temperature, the central control system 6 automatically stops the cooling fan 72 or reduces the rotation speed of the cooling fan 72. This operation is repeated.

[0052] A specific example is shown below. The appropriate operating temperature of the power battery is set to the range T1-T2, with T1 being 25°C and T2 being 40°C. A temperature sensor 73 installed on the power battery senses the current temperature T0 of the battery. If T0 is less than T1, the central control system 6 automatically controls the cooling fan 72, directing warm air from the cooling / heating system 2 towards the power battery to raise its temperature. If the operating temperature of the power battery is within the T1-T2 range, the central control system 6 automatically stops the cooling fan 72 or reduces its rotation speed. If T0 exceeds T2, the central control system 6 automatically controls the cooling fan 72, directing cool air from the cooling / heating system 2 towards the power battery to lower its temperature. If the operating temperature of the power battery is within the T1-T2 range, the central control system 6 automatically stops the cooling fan 72 or reduces its rotation speed. This operation is repeated. Of course, the cooling / heating system 2 is controlled by the central control system 6. The specific temperature control of the drive control system is similar to the temperature control principle of the power battery. However, the appropriate operating temperature range may differ slightly. For example, the appropriate operating range for the drive control system is between 20°C and 45°C.

[0053] The control method of the present invention effectively controls the operating temperature of a power battery or drive control system, adapting it to different working environments such as extreme cold or high temperatures, thereby extending its lifespan and reducing the occurrence of failures. Furthermore, the control is simple and highly reliable.

[0054] Finally, the above embodiments are for illustrating, and not limiting, the technical solutions of the present invention. Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art should understand that it is still possible to modify the technical solutions described in the above embodiments or to replace some of their technical features with equivalent substitutes. These modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of each embodiment of the present invention.

When the temperature of the power battery or drive control system reaches the set operating temperature range, the central control system (6) automatically stops the cooling fan (72) or reduces its rotational speed. This operation is repeated.
