Description

Technical Field

[0001] The invention relates to an integrated system of a vehicle air conditioner and a cooling or heating device and a control method. Background Art

[0002] The traditional automobile air conditioning centralized air supply system includes air inlet duct, cooling / heating system and air supply duct, such as Figure 1 , Figure 2 As shown, the air inlet duct is provided with two air inlets, one air inlet 1a is used to deliver fresh air, and the other air inlet 2a is used to deliver internal circulating air. The outlet of the air inlet duct is connected to the cooling / heating system, and the outlet of the cooling / heating system is connected to the air supply duct. The cooling / heating system includes a high-power air supply fan 3a, an evaporator 4a, a compressor, a throttle valve, a condenser and a cooling fan. The cooling / heating system cools the air in the air inlet duct and then delivers it to the air supply duct. A plurality of air outlet ducts 5a are provided at the end of the air supply duct. The outlets of the air outlet ducts 5a are located in different areas of the car passenger compartment. A valve switch is provided at the end of the air outlet duct to control the air output. The traditional automobile air conditioning air supply system has the following disadvantages: 1. The high-power air supply fan is large in size and is placed in the automobile engine compartment, which seriously restricts the spatial layout of the engine compartment; 2. After the high-power air supply fan sends out the cold air / hot air, it is transmitted through the air supply duct, especially the long-distance duct transmission in the rear area, which causes serious air loss and reduces the energy efficiency of the air supply system; 3. The air supply fan of the centralized air supply system directly sends the cold air / hot air to the end of the air outlet duct and blows it onto the passengers, causing the passengers' body temperature to change too quickly and reducing their comfort; 4. The centralized air supply system cannot perform differentiated air supply management on the ends of each air outlet. Passengers in different positions cannot set different fan speeds according to their respective needs. They can only set valves at each air outlet to intercept the air volume by switching the size of the valve, resulting in air volume waste; 5. The air supply fan of the centralized air supply system directly sends the cold air to the end of the air outlet and blows it onto the passengers, causing the passengers' body temperature to change too quickly and reducing their comfort. 6. Traditional cars replace fresh air by using the inertia of the vehicle as it moves forward. However, unmanaged hot and cold air from the outside will affect the air conditioning effect in the car, increasing energy consumption while reducing passenger comfort.

[0003] In addition, with the development of new energy electric vehicles, the three core components of electric vehicles, the drive motor, power battery and drive control system, are the most seriously heated components, and their heat dissipation system is particularly important. The traditional manufacturing method is to use liquid cooling to cool the drive motor and drive control system by laying liquid cooling pipes, but laying liquid cooling pipes also involves sealing issues, resulting in complex product structure, high manufacturing costs, and low integration. After research and experiments, it was found that the drive motor is the most seriously heated, and liquid cooling must be used to take away the working heat in time, but the power battery and drive control system are relatively low in heat when working, and air cooling can be used to meet the heat dissipation requirements, which can reduce the troubles caused by laying liquid cooling pipes, simplify the structure, and reduce manufacturing costs.

[0004] Third, the drive motors, power batteries and drive control systems of some electric vehicles in extremely cold environments must not only consider the heat dissipation problem, but also pay attention to the problem that the power batteries and drive control systems can only start and work normally at a reasonable operating temperature.

[0005] Therefore, it is necessary to redesign a new system to effectively control the operating temperature of the power battery and drive control system. Summary of the invention

[0036] like Figure 4 As shown, the cooling / heating system 2 further includes a compressor, a throttle valve, a condenser and a cooling fan.

[0037] The terminal air supply system 4 described above is controlled by the central control system 6, the cooling fan 72 of the cooling or heating device 7 is controlled by the central control system 6, the power battery and / or the drive control system is equipped with a temperature sensor 73, the temperature sensor 73 measures the operating temperature of the power battery and / or the drive control system and sends it to the central control system 6, and the central control system 6 uses the cooling fan 72 to dissipate or heat the power battery and / or the drive control system on the vehicle according to the operating temperature of the power battery and / or the drive control system.

[0038] Advantages of the present invention: 1. The vehicle air conditioner is integrated with the cooling or heating device, and an air-cooling design is adopted for the power battery and / or the drive control system. The cooling or heating device is re-embedded in the vehicle air conditioning system. The cooling or heating device includes a plurality of third pipes provided at the end of the air supply pipe, and a cooling fan is installed in each third pipe. The cooling fan dissipates the low / high temperature airflow output by the refrigeration / heating system to dissipate or heat the power battery and / or the drive control system on the vehicle. The structure can be simplified, the manufacturing cost can be reduced, and the integration is high. 2. The present invention adds the terminal power air outlet of the power air outlet system to the power battery or the drive control system, that is, a plurality of third pipes are provided at the end of the air supply pipe, and a cooling fan is installed in each third pipe. At the same time, the temperature of the battery or the drive system is sensed, and the central control system is centrally and automatically controlled through the central control system 6, so as to realize the comprehensive use and centralized control of the energy of the vehicle air conditioner and cooling system, thereby realizing vehicle energy saving.

[0039] like Figure 5 As shown, the power air outlet system 100 has a fresh air device 5, which includes a first pipe 51 and a second pipe 53. A suction fan 52 is installed in the first pipe 51. Under the action of the suction fan 52, the inlet of the first pipe 51 is used to actively suck fresh air into the interior of the vehicle. An exhaust fan 54 is installed in the second pipe 53. The inlet of the second pipe 53 is connected to the interior of the vehicle. Under the action of the exhaust fan 54, the turbid air in the interior of the vehicle is discharged out of the vehicle through the outlet of the second pipe 53. Fans are provided inside the first pipe 51 and the second pipe 53, respectively at the front end and the rear end of the pipes. The two fans form a siphon effect in the pipes to generate negative pressure, thereby improving the air volume energy efficiency of the fan system. The suction fan 52 and the exhaust fan 54 can be centrally controlled by the central control system 6 of the air conditioner, effectively managing the energy consumption of the vehicle air conditioning system and improving the comfort of passengers.

[0040] The above-mentioned suction fan 52 and exhaust fan 54 are both ducted high-speed small fans.

[0041] The terminal air supply system 4 is controlled by the central control system 6 .

[0042] The exhaust fan 54 is controlled by the central control system 6 .

[0043] The low-power air supply fan 41 is located obliquely behind the low-speed fan 42. The high-speed low-power air supply fan 41 blows the low / high temperature airflow of the cooling / heating system 2 to the rear of the low-speed fan 42. The low-speed fan 42 mixes the low / high temperature airflow with the ambient temperature airflow and blows it to the user's position. The low-speed fan 42 mixes the low / high temperature airflow with the ambient temperature airflow to make the wind temperature and wind speed more comfortable.

[0044] The terminal air supply system 4 described above also includes an air supply control unit 43, which controls the operation of the high-speed, low-power air supply fan 41 and the low-speed fan 42 of the terminal air supply system 4 in which it is located, and the central control system 6 controls the operation of each air supply control unit 43. Users in different locations can set the wind speed of the terminal air supply system 4 according to their personal needs, which better meets the differentiated needs of users and enhances the user experience. The air supply control unit 43 can actually be an integrated motor controller that can control the operation of the low-power air supply fan 41 and the low-speed fan 42 at the same time. The central control system 6 is the central control system of the air conditioner and will not be described in detail here.

[0045] The terminal air supply system 4 further includes an infrared / temperature sensing system 44, which senses the state of the user's position and sends a sensing signal to the central control system 6, which controls the operation of each air supply control unit 43 according to the sensing signal. The central control system 6 can control the operation of each terminal air supply system 4 differently.

[0046] The air supply angles of the above-mentioned low-power air supply fan 41 and low-speed fan 42 are both adjustable, for example, the air supply angle can be adjusted within the range of 10 degrees to 90 degrees.

[0047] The above-mentioned user location status includes user perception, temperature perception and sleep perception.

[0048] The infrared / temperature sensing system 44 can identify whether there is an occupant in the seat, whether the user is sleeping, and whether the user's body temperature is too high or too low, and automatically adjust to the optimal temperature and wind speed conditions for different user positions through the centralized control system, thereby improving user comfort and saving energy.

[0049] The suction fan 52 and the exhaust fan 54 are both controlled by the central control system 6. An air conditioning device 55 is also installed in the first pipe 51. The air conditioning device 55 includes a filter, a surface cooler and a humidifier. A fresh air temperature sensor 57 and a fresh air valve 56 are set at the fresh air inlet end of the first pipe 51. The fresh air temperature sensor 57 sends the detected temperature signal to the central control system 6, and the central control system 6 controls the fresh air valve 56 and the air conditioning device 55 to work. The fresh air temperature sensor 57 sends the detected temperature signal to the central control system 6, and the central control system 6 controls the fresh air valve 56 and the air conditioning device 55 to work. The central control system 6 controls the fresh air valve 56 to open or close, thereby controlling the entry of fresh air.

[0050] By improving the power vent system, the car can be more energy-efficient and the passengers (i.e. users) can experience a more comfortable experience. The advantages are:

[0051] 1. In automotive applications, the high-power centralized air supply fan inside the engine compartment is cancelled, and a high-power air supply fan 21 is added to the centralized air supply duct instead, which can better arrange the space of the engine compartment and improve the rationality of the compartment space design;

[0052] 2. In automotive applications, the wind blown out by the high-power air supply fan 21 is compensated by adding a high-speed low-power air supply fan in the end pipe of the air outlet, so that a siphon effect is formed in the pipe to generate negative pressure, reduce the air volume attenuation of cold air (or hot air) in the pipe, and improve the air supply energy efficiency of the fan system;

[0053] 3. In automobile applications, each air outlet duct 31 has an independent air supply control unit 43, which controls the low-power air supply fan 41 of each air outlet duct 31 respectively; at the same time, there is also a central control system 6 in the center console for centralized control, which can differentially control the speed of the low-power air supply fan 41 of each air outlet duct 31.

[0054] 4. A low-power air supply fan 41 is provided in each air outlet duct 31. Personnel at different positions can set the rotation speed of different low-power air supply fans 41 according to their personal needs, thereby better meeting the differentiated needs of personnel and improving the personnel's experience.

[0055] 5. An infrared / temperature sensing system 44 is added to each air outlet duct 31 to identify whether there is a person at the seat, whether the person is sleeping, and whether the person's body temperature is too high or too low. The central control system 6 automatically adjusts the temperature and wind speed to the optimal state for different positions of the person, thereby improving the comfort of the person;

[0056] 6. Add a low-speed fan 42 to each air outlet duct 31 to mix the ambient air with the cold (hot) air blown out by the low-power air supply fan 41 and blow it onto the personnel, forming a natural wind to improve the comfort of the personnel;

[0057] 7. The new air-conditioning air supply system can achieve constant air volume control, reduce the risk of reduced air volume due to increased static pressure in the pipeline caused by factors such as filter blockage, and improve the experience of air-conditioning cooling effect.

[0058] Embodiment 2

[0059] like Figure 6 and Figure 7As shown, a control method for a vehicle air conditioning and cooling or heating device integrated system, the vehicle air conditioning and cooling or heating device integrated system adopts the vehicle air conditioning and cooling or heating device integrated system described in Example 1, and is characterized in that: its control method is as follows: the temperature of the power battery or the drive control system is sensed by the temperature sensor 73. When the temperature is higher or lower than the effective operating temperature range of the power battery or the drive control system, the temperature sensor will transmit a signal to the central control system 6. The central control system 6 will automatically control the cooling fan 72 to blow the cold air or hot air output by the refrigeration / heating system 2 to the power battery or the drive control system to dissipate heat or heat the power battery or the drive control system. After the temperature of the power battery or the drive control system reaches the set safe operating temperature, the central control system 6 will automatically turn off the cooling fan 72 or reduce the speed of the cooling fan 72, and work in this reciprocating cycle.

[0060] A specific example is as follows. Assuming that the appropriate operating temperature of the power battery is set in the T1-T2 range, T1 is equal to 25 degrees Celsius, and T2 is equal to 40 degrees Celsius, the temperature sensor 73 installed on the power battery senses the current temperature T0 of the power battery. When T0 is less than T1, the central control system 6 will automatically control the cooling fan 72 to blow the hot air output by the cooling / heating system 2 to the power battery to increase the temperature of the power battery. When the operating temperature of the power battery is in the T1-T2 range, the central control system 6 will automatically turn off the cooling fan 72 or reduce the speed of the cooling fan 72; when T0 is greater than T2, the central control system 6 will automatically control the cooling fan 72 to blow the cold air output by the cooling / heating system 2 to the power battery to cool the power battery. When the operating temperature of the power battery is in the T1-T2 range, the central control system 6 will automatically turn off the cooling fan 72 or reduce the speed of the cooling fan 72, and the cycle will be 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 the same as the temperature control principle of the power battery. However, the appropriate operating temperature range may be slightly different. For example, the appropriate operating range of the drive control system is between 20 degrees Celsius and 45 degrees Celsius.

[0061] The control method of the present invention can effectively control the operating temperature of the power battery or the drive control system, and is suitable for different working environments of severe cold or high temperature, thereby extending its service life and reducing the occurrence of faults, and the control is simple and reliable.

[0062] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the embodiments of the present invention.
