[0002] The vehicle thermal management system is a crucial auxiliary system ensuring the normal and stable operation of all vehicle components. To keep the engine, motor, battery, and other components in optimal working condition, proper thermal management is essential. This ensures that the heat removed by the cooling system remains within an optimal range, preventing engine unreliability caused by overheating, such as a decrease in the charging coefficient, abnormal combustion leading to knocking, pre-ignition, oil deterioration, and burning. Conversely, it avoids excessive cooling, which can result in excessive heat loss, increased effective power loss, and increased mechanical losses due to friction and wear of parts.

[0042] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0043] Example 1:

[0044] An air filter heat exchange method, see Figure 1 It is used in vehicles, which include a connected air filter module and a drive module. The air filter module includes an evaporator and a condenser.

[0045] The methods include:

[0046] S11: Perform temperature detection on the vehicle's environment and / or drive module, and obtain the temperature detection results;

[0047] S12: Match the temperature detection results with the preset heat exchange temperature range;

[0048] S13: Based on the matching result, start the evaporator to cool the gas entering the air filter module or start the condenser to heat the gas entering the air filter module.

[0049] The beneficial effects of this embodiment are as follows: Addressing the problem of poor integration in existing air filter modules, this embodiment provides a highly integrated air filter module that integrates both the evaporator and condenser, improving the integration and compactness of the engine air filter module and increasing space utilization. Furthermore, after determining the vehicle's operating temperature, the air filter module can directly utilize the evaporator to cool the intake air or directly utilize the condenser to heat the intake air, simplifying the air filter's heat exchange method and increasing the applicable temperature range of the air filter module.

[0050] Based on the above embodiments, for S11, it can be seen that the temperature detection result includes three cases: the first is the temperature detection result obtained by only detecting the temperature of the environment in which the vehicle is located; the second is the temperature detection result obtained by only detecting the temperature of the drive module; and the third is the temperature detection result obtained by simultaneously detecting the temperature of both the environment in which the vehicle is located and the drive module.

[0051] Preferably, in the embodiment, the temperature detection result in S11 includes the temperature detection result of the environment in which the vehicle is located, and the preset heat exchange temperature range includes a first range and a second range, wherein the temperature corresponding to the first range is higher than the temperature corresponding to the second range.

[0052] Based on the matching results, the evaporator is activated to cool the gas entering the air filter module, or the condenser is activated to heat the gas entering the air filter module, including:

[0053] Once the temperature of the vehicle's environment is determined to meet the first temperature range, the evaporator is activated to cool the gas entering the air filter module.

[0054] Once the temperature of the vehicle's environment is determined to meet the second temperature range, the condenser is activated to heat the gas entering the air filter module.

[0055] The beneficial effect of adopting the preferred solution in the above embodiments is that the temperature detection results of this preferred embodiment can only include the temperature of the vehicle's environment: by setting a first interval and a second interval with different corresponding temperatures, it is convenient to divide the temperature detection results belonging to different heat exchange temperature ranges, thereby determining the specific temperature interval to which the temperature detection results of the vehicle's environment belong, and thus determining whether the current temperature detection results of the vehicle's environment belong to a low temperature or a high temperature. In this embodiment, when the temperature detection results of the vehicle's environment belong to the temperature corresponding to the first interval, it indicates that the vehicle is in a high-temperature environment, and the evaporator needs to be turned on to cool the gas entering the air filter module; when the temperature detection results of the vehicle's environment belong to the temperature corresponding to the second interval, it indicates that the vehicle is in a low-temperature environment, and the condenser needs to be turned on to heat the gas entering the air filter module.

[0056] Preferably, in this embodiment, the air filter module is further provided with an air-heat exchanger, and the preset heat exchange temperature range includes a third range, the temperature of which is lower than the temperature of which is the second range. The method further includes:

[0057] Once the temperature of the vehicle's environment is determined to be within the third range, the condenser and heat exchanger are activated to heat the gas entering the air filter module.

[0058] The beneficial effect of adopting the preferred solution in the above embodiments is that the temperature detection result of this preferred embodiment may only include the temperature of the vehicle's environment. This embodiment also divides the environment into a third interval. It can be seen from the defined corresponding temperatures that the temperatures of the first interval, the second interval, and the third interval decrease sequentially. It can be seen that the temperature corresponding to the third interval is extremely low. By isolating the extremely low temperature environment, the accuracy of the judgment of the vehicle's environment is improved, and the components that the vehicle needs to start in this environment can be more accurately obtained, which has a protective effect on the vehicle's heating system or other related starting components. For example, when the temperature detection result of the vehicle's environment is the temperature corresponding to the third interval, it means that the vehicle is in an extremely low temperature environment, and it is necessary to turn on the condenser and the air heat exchanger at the same time to heat the gas entering the air filter module.

[0059] Preferably, in the embodiment, the temperature detection result also includes the temperature detection result for the drive module; the preset heat exchange temperature range also includes a fourth range and a fifth range, wherein the temperature corresponding to the fourth range is higher than the temperature corresponding to the fifth range;

[0060] Before starting the evaporator to cool the gas entering the air filter module, the method includes:

[0061] The temperature detection results of the drive module are confirmed to meet the fourth interval.

[0062] Before starting the condenser to heat the gas entering the air filter module, the method includes:

[0063] The temperature detection results of the drive module are confirmed to meet the fifth interval.

[0064] The beneficial effect of adopting the preferred solution in the above embodiments is that a fourth interval and a fifth interval are further provided for temperature matching based on the temperature detection results of the drive module, and the fourth interval and the first interval belong to the same high temperature environment, while the fifth interval and the second interval belong to the same low temperature environment.

[0065] This preferred embodiment addresses a temperature detection result that simultaneously includes the temperature of the vehicle's environment and the temperature of the drive module. Specifically, in step S11, the temperature detection result includes both the temperature of the vehicle's environment and the temperature of the drive module. Before initiating step S13, it is necessary to simultaneously determine which temperature range each of the drive module's temperature detection result and the vehicle's environment's temperature detection result corresponds to.

[0066] When the temperature detection result of the vehicle's environment meets the first interval and the temperature detection result of the drive module meets the fourth interval, it indicates that the vehicle's environment is a high-temperature environment, and the evaporator is started to cool the gas entering the air filter module.

[0067] When the temperature detection result of the vehicle's environment meets the second range and the temperature detection result of the drive module meets the fifth range, it indicates that the vehicle's environment is a low-temperature environment, and the condenser is activated to heat the gas entering the air filter module.

[0068] Preferably, in the embodiment, the preset heat exchange temperature range also includes a sixth range, the temperature of which is lower than that of the fifth range;

[0069] Before starting the condenser and air-heat exchanger to heat the gas entering the air filter module, the method includes:

[0070] The temperature detection results of the drive module are confirmed to meet the sixth interval.

[0071] The beneficial effect of adopting the preferred solution in the above embodiments is that a sixth interval is also provided for temperature matching based on the temperature detection results of the drive module, making the division of temperature intervals more detailed and facilitating precise control of the vehicle status. In this embodiment, before starting step S13, it is necessary to simultaneously determine which temperature interval each of the temperature detection results of the drive module and the temperature detection results of the vehicle's environment corresponds to. If the temperature detection results of the vehicle's environment meet the third interval and the temperature detection results of the drive module meet the sixth interval, then the condenser and the air heat exchanger are started to heat the gas entering the air filter module. At this time, the vehicle is in an extremely low temperature environment.

[0072] Preferably, in an embodiment, the drive module includes a connected engine 24 and an intake manifold 23, and the temperature detection results of the drive module include manifold temperature detection results for the intake manifold 23.

[0073] The beneficial effects of the preferred solution in the above embodiments are that, since the intake manifold is connected to the engine, detecting the temperature of the intake manifold can reflect the temperature near the engine, thereby facilitating the judgment of the vehicle drive module temperature, improving the accuracy of vehicle status judgment, and thus accurately determining the workpiece that needs to be opened by the vehicle, providing protection for the vehicle heating system or other related starting components. Furthermore, when detecting the temperature of the drive module, only the temperature at the intake manifold can be detected, or the temperature at other locations of the drive module besides the intake manifold can be detected simultaneously; that is, the temperature detection result of the drive module can include only one temperature data point at the intake manifold, or it can include multiple temperature data points.

[0074] Preferably, in this embodiment, both the evaporator and the condenser are connected to an electronic expansion valve 21.

[0075] After starting the evaporator to cool the gas entering the air filter module or starting the condenser to heat the gas entering the air filter module according to the matching result, the method further includes:

[0076] The system acquires the real-time temperature inside the vehicle and adjusts the opening of the electronic expansion valve 21 according to the real-time temperature to control the flow rate of refrigerant in the evaporator or condenser.

[0077] The beneficial effect of adopting the preferred scheme in the above embodiments is that by setting the electronic expansion valve 21, the refrigerant flow rate can be adjusted according to the actual temperature. For example, when the temperature is too high or too low, the opening of the electronic expansion valve 21 can be increased to increase the refrigerant flow rate, thereby improving the cooling or heating efficiency of the intake air; when the temperature is close to the set normal operating temperature, the opening of the electronic expansion valve 21 can be decreased to reduce the refrigerant flow rate. In summary, adjusting the opening of the electronic expansion valve 21 according to the real-time temperature makes it easier to control the intake air temperature within the range required by the engine 24. The real-time temperature can be the temperature in the drive module, such as the engine temperature or the temperature in the intake manifold.

[0078] Specifically, in winter environments, both turbocharged and naturally aspirated engines experience intake air temperatures below freezing. Water vapor in the crankcase ventilation exhaust condenses and rapidly freezes, causing crankcase pressure to rise, the oil dipstick to pop out, and engine oil to leak from engine 24, rendering engine 24 unable to operate normally. Therefore, the low temperatures of winter correspond to the extremely low temperature or low temperature state of this invention.

[0079] In high-temperature environments during summer, the vehicle corresponding to this invention is in a high-temperature state.

[0080] Examples of the three temperature states corresponding to the set temperature in S11 are as follows:

[0081] At extremely low temperatures, see Figure 2 , Figure 2 The diagram illustrates the connection structure under extremely low temperature conditions. The corresponding temperature judgment range can be set as follows (here, the temperature detection location of the drive module is set to the intake manifold; in actual use, the temperature detection location of the drive module can also be set to other locations): the ambient temperature of the vehicle is < -20℃ (corresponding to the temperature in the third range), and the intake manifold temperature is < 0℃ (corresponding to the temperature in the sixth range). When the ambient temperature of the vehicle and the temperature of the intake manifold 23 fall within the above ranges, the vehicle is judged to be in an extremely low temperature state. At this time, the air heater / air-heated PTC is triggered to operate, the air conditioning series condenser acts as a heat exchanger, and the air conditioning system adopts heat pump mode. At this time, the thermal efficiency is 1kW of electrical energy can transfer 1kW of heat to provide to the intake system (the air conditioning heat pump efficiency is significantly lower than that in the low temperature state, so an air heater / air-heated PTC must be used for auxiliary intake heating), effectively solving the problem of icing in the crankcase ventilation system pipes of the engine 24 in winter. Here, the air heater is the air-heated PTC.

[0082] At low temperatures, see Figure 3 , Figure 3The diagram shows the connection structure at low temperatures. The corresponding temperature range can be set as follows: -20℃ < ambient temperature of the vehicle < 0℃ (corresponding to the temperature in the second range), and intake manifold 23 temperature < 0℃ (corresponding to the temperature in the fifth range). When the ambient temperature of the vehicle and the temperature of the intake manifold 23 fall within the above ranges, the vehicle is judged to be in a low-temperature state. At this time, the vehicle's air conditioning system is triggered, the compressor runs, and the air conditioning condenser in series acts as a heat exchanger. The air conditioning system adopts a heat pump mode, consuming 1kW of electrical energy to transfer 2kW to 3kW of heat to the intake system. The heat pump mode is to transfer heat from outside the vehicle to inside the vehicle. The system has high efficiency and low power consumption, which helps to improve the battery's driving range.

[0083] At high temperatures, see Figure 4 , Figure 4 The diagram shows the connection structure under high-temperature conditions. The corresponding temperature judgment range can be set as follows: ambient temperature of the vehicle > 35℃ (corresponding to the temperature of the first interval), and intake manifold 23 temperature > 50℃ (corresponding to the temperature of the fourth interval). When the ambient temperature of the vehicle and the temperature of the intake manifold 23 fall within the above ranges, the vehicle is judged to be in a high-temperature state. At this time, the compressor runs, and the evaporator connected in series in the air filter module acts as a heat exchanger to cool the intake system. Consuming 1kW of electrical energy, 2kW to 3kW of heat can be transferred from the intake system to the environment. The system has high efficiency and low power consumption, which helps to improve the battery range. It effectively reduces the problem of intake manifold 23 overheating in summer and reduces the risk of engine 24 pre-ignition and knocking.

[0084] The temperature assessment and operations described above all take place after the vehicle is started.

[0085] contrast Figures 2-4 It can be seen that, due to Figure 2 Schematic diagram of the connection structure at extremely low temperatures. Figure 3 This is a schematic diagram of the connection structure at low temperatures. Figure 4 This is a schematic diagram of the connection structure under high temperature conditions, which shows that... Figure 2 , Figure 3 All are in intake heating mode. Figure 4 It is an intake air cooling mode; in addition, only Figure 2 The low-temperature conditions necessitated the use of a wind-heated PTC; here, Figure 2 The air-heated PTC mentioned is an air-heated heater.

[0086] exist Figures 2-4 In this context, due to different specific temperature conditions, "evaporator & condenser" only indicates that the air filter module integrates both an evaporator and a condenser; it does not mean that both devices are turned on simultaneously. The two devices are used in a selective manner. Figure 2 , Figure 3The intake heating mode currently in use only utilizes the condenser, while Figure 4 The intake cooling mode currently in use only utilizes the evaporator.

[0087] When measuring the vehicle's ambient temperature and the temperature of the intake manifold 23, a corresponding temperature sensor can be installed at a suitable location on the vehicle to obtain the ambient temperature and the temperature of the intake manifold 23. When the vehicle is detected to be at a normal temperature, such as 0℃~35℃, the air filter module of this application will not be automatically turned on; the driver only needs to manually select to turn it on, which can achieve the effect of energy saving.

[0088] In some embodiments, see Figures 2-4 The electronic expansion valve 21 has a one-way valve structure, and each figure has two electronic expansion valves 21: see Figures 2-3 When the temperature is extremely low or low, the condenser is connected, the check valve in the left electronic expansion valve 21 is closed, and the check valve in the right electronic expansion valve 21 is connected. When connected, it reduces resistance; when closed, it throttles the expansion. See also Figure 4 When the temperature is high, the evaporator is connected, the one-way valve in the left electronic expansion valve 21 is connected, and the one-way valve in the right electronic expansion valve 21 is closed.

[0089] Example 2:

[0090] An air filter heat exchange device, see Figure 5 This device is used in vehicles, where the vehicle includes a connected air filter module and a drive module. The air filter module includes an evaporator and a condenser. The device also includes:

[0091] The temperature detection module is used to detect the temperature of the vehicle's environment and / or drive module, and obtain the temperature detection results.

[0092] The matching module is used to match the temperature detection results with a pre-set heat exchange temperature range.

[0093] The control module is used to start the evaporator to cool the gas entering the air filter module or to start the condenser to heat the gas entering the air filter module based on the matching result.

[0094] Furthermore, the temperature detection results include the temperature detection results of the vehicle's environment. The pre-set heat exchange temperature range includes a first range and a second range, with the temperature corresponding to the first range being higher than the temperature corresponding to the second range. The control module is used to start the evaporator to cool the gas entering the air filter module when it is determined that the temperature detection results of the vehicle's environment meet the first range; and to start the condenser to heat the gas entering the air filter module when it is determined that the temperature detection results of the vehicle's environment meet the second range.

[0095] Furthermore, the air filter module is also equipped with a heat exchanger. The preset heat exchange temperature range includes a third range, the temperature of which is lower than that of the second range. The control module is also used to start the condenser and heat exchanger to heat the gas entering the air filter module when the temperature detection result of the vehicle's environment meets the third range.

[0096] The beneficial effects of this embodiment are: the temperature detection module is used to detect the temperature, the matching module is used to match the temperature detection result with the preset heat exchange temperature range, and the control module controls the air filter module to turn on the evaporator or condenser according to the matching result, thereby adjusting the intake air temperature.

[0097] Based on the above embodiments, the air filter module is equipped with a solenoid valve 22, which is used to adjust the connection between the evaporator and condenser within the air filter module, allowing for convenient and rapid adjustment. Specifically, the solenoid valve 22 can be a two-position five-way solenoid valve, which connects the evaporator and condenser, facilitating control of the valve based on the vehicle's operating temperature to adjust the connection between the evaporator and condenser. Optionally, the two-position five-way solenoid valve is connected to a compressor, and a water-to-intercooler or an air-to-intercooler can be installed between the air filter module and the engine 24. After intake air enters the engine 24, it sequentially enters the cylinder head intake manifold, intake valves, and combustion chamber.

[0098] In some embodiments, one end of the air filter module is used for air intake, and the other end is connected in sequence to the intake manifold 23 and the engine 24; the device intakes air through the air filter module, then adjusts the intake air temperature in the air filter module, and then passes the intake air into the intake manifold 23 and the engine 24 in sequence.

[0099] Furthermore, the temperature detection results also include the temperature detection results for the drive module; the preset heat exchange temperature range also includes a fourth range and a fifth range, with the temperature corresponding to the fourth range being higher than the temperature corresponding to the fifth range; before starting the evaporator to cool the gas entering the air filter module, the method includes: determining that the temperature detection results of the drive module meet the fourth range; before starting the condenser to heat the gas entering the air filter module, the method includes: determining that the temperature detection results of the drive module meet the fifth range.

[0100] Furthermore, the pre-set heat exchange temperature range also includes a sixth range, the temperature of which is lower than that of the fifth range; before starting the condenser and air heat exchanger to heat the gas entering the air filter module, the method includes: determining that the temperature detection result of the drive module meets the sixth range.

[0101] Furthermore, the drive module includes a connected engine and an intake manifold, and the temperature detection results of the drive module include manifold temperature detection results for the intake manifold.

[0102] Furthermore, both the evaporator and the condenser are connected to electronic expansion valves. After the evaporator is activated to cool the gas entering the air filter module or the condenser is activated to heat the gas entering the air filter module according to the matching result, the method also includes: acquiring the real-time temperature inside the vehicle and adjusting the opening of the electronic expansion valve according to the real-time temperature to control the flow rate of refrigerant in the evaporator or condenser.
