Description

Technical Field

[0001] The present application relates to the field of automobile control technology, and specifically to an air spring damper heat dissipation system and a heat dissipation method. Background Art

[0002] Automobile shock absorbers are a crucial component of the vehicle's suspension system, primarily buffering ground impacts on the vehicle and improving vehicle comfort and handling. Shock absorbers with air springs are currently widely used in the automotive industry. A typical shock absorber with an air spring includes an air spring and a height sensor. The air spring is located between the vehicle body and the spring tray on the suspension, providing both cushioning and vibration reduction functions. Two height sensors are provided, one on the vehicle frame and the spring tray, one on the frame and the upper arm, or one on the frame and the lower arm. The height sensors detect the vehicle's height and transmit this signal to an electronic control unit (ECU). The ECU then adjusts the vehicle's posture based on the height signal. The ECU adjusts the vehicle's posture based on the height signal and the vehicle's state. During this adjustment, the ECU activates an air supply and distribution module to deliver air between the air tank and the air spring. The air supply and distribution module can be, for example, an air compressor.

[0003] During vehicle operation, the air in the air spring chamber is frequently compressed, causing its temperature to rise. Excessively high temperatures can affect the performance of the air spring and reduce driving comfort. To address this technical issue, prior art proposes an air supply device for air suspension. This device includes an air pump, an air drying chamber for drying the compressed air, and an external motor for driving the air pump. The air pump is independently connected to the reversing valve assembly or the air drying chamber, either directly or through a cooling device. This solution reduces the temperature of the air entering the drying chamber by adding a cooling device, thereby improving the drying capacity of the air drying chamber and the service life of the air supply device. This solution can reduce the temperature of the gas entering the air spring to a certain extent, thereby improving the performance of the air spring. However, because a cooling device needs to be added to the entire pipeline, the cost of the entire air suspension will increase, which is not conducive to large-scale promotion and application. In addition, the added cooling device is mainly used to facilitate the drying of the gas, and has a poor cooling effect on the gas entering the air spring. Furthermore, the heat generated by the compression of the air spring is a harmful heat source for the air spring itself, but for other structures on the car, this heat source can be utilized, but this is not addressed in the current existing technology, resulting in energy waste.

[0031] When the air conditioner is in heating mode, external air is selected to supply air to the air spring, and the waste heat of the gas inside the air spring is recovered, and the gas inside the air spring is recovered to the air inlet of the air conditioner.

[0032] According to a heat dissipation method for an air spring shock absorber provided in the present application, the method for determining whether the air spring needs to be cooled includes: comparing the internal gas temperature of the air spring with a set temperature; if the internal gas temperature of the air spring is not less than the set temperature, the air spring has a heat dissipation requirement; if the internal gas temperature of the air spring is less than the set temperature, the air spring has no heat dissipation requirement.

[0034] According to a heat dissipation method for an air spring shock absorber provided in the present application, when the waste heat of the gas inside the air spring is recovered, the third pipeline is connected and the fourth pipeline is cut off, and the gas inside the air spring is discharged to the air inlet of the air conditioner; when the waste heat of the gas inside the air spring is not needed to be recovered, the third pipeline is cut off and the fourth pipeline is connected, and the gas inside the air spring is discharged to the external environment.

[0035] The advantages of the present application are as follows: 1. The air spring shock absorber heat dissipation system of the present application introduces four pipeline structures and an air supply module. The two pipelines are respectively connected to the air-conditioning outlet, the external environment and the air supply module. The air supply module can select the air with lower temperature to supply to the air spring according to the comparison between the air-conditioning outlet temperature and the external air temperature, so that the internal air temperature of the air spring drops rapidly, which has an excellent heat dissipation effect on the air spring, can always maintain the air spring in a good use condition, and extend the service life of the air spring; at the same time, the other two pipeline structures provided by the present application are connected to the outlet of the air spring and the air-conditioning inlet The air spring is connected to the external environment, and the heat energy of the high-temperature gas inside the air spring can be selectively recovered when the air spring is in the heat dissipation mode. The high-temperature gas discharged by the air spring can be introduced into the air inlet of the air conditioner, so that the temperature of the air entering the air inlet of the air conditioner is greatly increased, thereby improving the heating efficiency of the air conditioner and saving heating energy under low temperature conditions in winter. In addition, the present application only adds four pipeline structures, the improvement is minimal, the cost is extremely low, and it does not occupy too much space. There is no need to configure special cooling equipment. The entire operation and control method is also extremely simple and low-cost to use, which is suitable for large-scale promotion and application.

[0036] 2. This application adds a first temperature sensor inside the air spring. The first temperature sensor can directly obtain the temperature of the gas inside the air spring. The obtained temperature more intuitively reflects the internal temperature of the air spring, and the subsequent adjustment and control of the air spring is more accurate. Temperature sensors are set at the inlet end of the second pipeline and the air outlet of the air conditioner. They can directly obtain the external ambient gas temperature and the air outlet temperature of the air conditioner, and can filter out the gas temperature with a lower temperature, which facilitates the rapid cooling and adjustment of the gas inside the air spring and the determination of whether waste heat recovery is needed. The heating efficiency of the air conditioning system is always at the best effect.

[0037] 3. The present application sets a first connecting pipe between the first pipe and the second pipe, and uses a first three-way valve on the first connecting pipe to control the opening and closing of the first pipe and the second pipe, which can greatly reduce the complexity of the entire pipe structure, facilitate the control and adjustment of the air intake of the air spring, and the air intake control circuit of the air spring is easy to arrange and occupies little space, further reducing the cost of manufacture and use.

[0038] 4. In the present application, a second connecting pipe is provided between the third and fourth pipes, and a second three-way valve on the second connecting pipe is used to control the opening and closing of the third and fourth pipes. This can significantly reduce the complexity of the entire pipe structure, facilitate the control and adjustment of the air spring exhaust, and the air spring exhaust control circuit is easy to arrange and occupies little space, further reducing the cost of manufacture and use.

[0039] 5. This application determines whether the air spring needs to be cooled by comparing the internal gas temperature of the air spring with the set temperature. In fact, it provides low-temperature gas to the air spring. This judgment module can be integrated into the control system to automatically and intelligently control the air spring. It can accurately determine whether the air spring needs to be supplied with low-temperature gas, thereby improving the use effect and service life of the air spring.

[0040] 6. When the air spring has a need for heat dissipation and the air conditioner is in cooling mode, the second judgment module of the present application can control the first pipeline and the second pipeline accordingly by comparing the air conditioner outlet temperature with the external ambient air temperature. This can provide the air supply module with lower temperature gas and inject it into the air spring, thereby achieving a good heat dissipation effect. The judgment logic of the second judgment module is simple.

[0041] 7. In this application, when the air spring has a heat dissipation requirement and the air conditioner is in heating mode, the external air is directly used as the source of low-temperature gas provided by the air supply module to the air spring. At this time, considering that the air conditioner module is in heating mode, the gas at the air conditioner outlet is no longer suitable for supplying to the air spring. Therefore, the external air is directly used as the source of gas for supplying the air spring. The judgment mode is very simple.

[0042] 8. In this application, when the air spring has a need for heat dissipation and the air conditioner is in heating mode, the air supply module injects external air into the air spring and discharges the high-temperature air inside the air spring. The temperature of the discharged high-temperature air is much higher than the external air temperature, and waste heat can be directly recovered to achieve the best thermal energy utilization efficiency and reduce heating energy consumption in cold winter.

[0043] 9. The present application also provides an air spring shock absorber heat dissipation method. The air spring shock absorber heat dissipation method of the present application is very simple and has multiple functions. First, it can determine whether the air spring needs to be cooled. Second, it can determine which gas to use to cool the air spring when the air spring needs to be cooled and the air conditioner is in cooling mode. Third, it can quickly determine the source of the gas for cooling the air spring when the air spring needs to be cooled and the air conditioner is in heating mode, and recover the waste heat of the exhaust gas from the air spring. The entire heat dissipation method is simple and efficient, and the heat dissipation efficiency of the air spring is extremely high. It always maintains the air spring in a good use condition, extends the service life of the air spring, improves the heating efficiency of the air conditioner, and saves heating energy in low temperatures in winter.

[0044] This application is applied to the heat dissipation of air spring shock absorbers, and has extremely high heat dissipation efficiency for air springs, which can always maintain the air springs in a good use condition and extend the service life of the air springs; and improve the heating efficiency of air conditioners when heating is needed in winter, which can reduce winter heating energy consumption under low temperature conditions in winter.

Thus, a feature specified as "first" or "second" may explicitly or implicitly include one or more of the features.

[0052] The present application will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0053] The present application relates to an air spring damper heat dissipation system. The heat dissipation system of the present application can automatically determine the usage of the air spring and whether the air spring needs to be cooled. The heat dissipation of the air spring of the present application refers to injecting low-temperature air into the gas chamber of the air spring, causing the high-temperature air in the gas chamber of the air spring to be discharged, so that the air spring can quickly achieve the effect of heat dissipation and temperature reduction. The air spring can always be maintained in good operating conditions, significantly extending the service life of the air spring and ensuring that the air spring always has good application effects. The present application has two sources of low-temperature gas for heat dissipation of the air spring: one is the air outlet of the air conditioner in cooling mode, and the other is external air. The present application detects these two gases and selects the gas with lower temperature as the gas source to more efficiently cool the air spring. The overall control method is very simple. When the air conditioner is in heating mode, the air from the air conditioner outlet is no longer used as heat dissipation gas, but directly uses external air as heat dissipation gas. The waste heat of the high-temperature gas discharged from the air spring is recovered, maximizing the use of every bit of heat source for winter heating, which can effectively reduce winter heating energy consumption.

[0054] Specifically, such as Figure 1 As shown, an air spring shock absorber heat dissipation system of the present application includes an air supply module, a pipeline module, a temperature acquisition module, an air conditioning mode acquisition module and a control module. The air supply module is actually an ASU air supply unit, which has a gas-driven device such as a blower inside, which can increase the internal gas pressure and inject the gas into the gas chamber of the air spring. The function of the air supply module is to supply air to the air spring 1.

[0055] like Figure 1 As shown, the pipeline module of the present application includes a first pipeline 3, a second pipeline 4, a third pipeline 5 and a fourth pipeline 6 provided with a control valve. One end of the first pipeline 3 is connected to the air outlet of the air conditioner and the other end is connected to the air supply module 2. One end of the second pipeline 4 is connected to the external environment and the other end is connected to the air supply module 2. One end of the third pipeline 5 is connected to the gas chamber of the air spring 1 and the other end is connected to the air inlet of the air conditioner. One end of the fourth pipeline 6 is connected to the gas chamber of the air spring 1 and the other end is connected to the external environment. The first pipeline 3 and the second pipeline 4 correspond to the air inlet of the air spring 1. The first pipeline 3 and the second pipeline 4 discharge the gas into the air supply module 2, and then the air supply module 2 injects the gas into the gas chamber of the air spring 1. The third pipeline 5 and the fourth pipeline 6 correspond to the exhaust port of the air spring 1. When the air supply module 2 injects high-pressure gas into the gas chamber of the air spring 1, the gas in the gas chamber of the air spring 1 can be discharged to the third pipeline 5 or the fourth pipeline 6 through the exhaust port, thereby achieving the effect of replacing the gas inside the gas chamber of the air spring 1, thereby realizing rapid cooling and heat dissipation.

[0056] The temperature acquisition module is used to collect the internal air temperature of air spring 1, the external ambient air temperature, and the air temperature at the air conditioner outlet. By obtaining the internal air temperature of air spring 1, it is possible to determine whether air spring 1 needs to be cooled. By comparing the external ambient air temperature with the air conditioner outlet temperature, it is possible to determine which gas is used as the cooling gas source.

[0057] The air conditioning mode acquisition module is used to obtain the current air conditioning mode. There are many air conditioning modes, such as heating, cooling, ventilation, dehumidification, etc. Therefore, except for heating and cooling, the air outlet temperature of the air conditioner is the same as the air inlet temperature, that is, the external ambient gas temperature is consistent with the air outlet temperature of the air conditioner. These situations are not within the scope of discussion of this application. This application only discusses the situations where the air outlet of the air conditioner is in cooling and heating modes.

[0058] The control module controls the first pipeline 3, the second pipeline 4, the third pipeline 5, the fourth pipeline 6 and the air supply module 2 based on the internal gas temperature of the air spring 1, the external ambient gas temperature, the air conditioning outlet temperature, and the air conditioning mode, so as to achieve heat dissipation and waste heat recovery of the air spring 1 shock absorber.

[0059] When the heat dissipation system of the present application is actually controlled, Figure 2 As shown, follow these steps:

[0060] S1, collecting the gas temperature in the air spring 1 and determining whether the air spring 1 needs to be cooled;

[0061] S2. When air spring 1 has a heat dissipation requirement, obtain the current air conditioning mode;

[0062] S21. When the air conditioner is in cooling mode, the air outlet temperature of the air conditioner is compared with the outside air temperature, and based on the comparison result, low-temperature gas is supplied to the air spring 1 to achieve heat dissipation;

[0063] S22. When the air conditioner is in heating mode, select external air to supply air to the air spring 1, recover waste heat from the gas inside the air spring 1, and recover the gas inside the air spring 1 to the air inlet of the air conditioner;

[0064] S23. When there is no need to recover the waste heat of the gas inside the air spring 1, discharge the gas inside the air spring 1 to the external environment.

[0065] During the heat dissipation process, as long as the gas temperature inside the gas chamber of the air spring 1 meets the requirement, the gas supply to the gas chamber of the air spring 1 can be stopped.

[0066] In some embodiments of the present application, the present embodiment optimizes the structure of the above-mentioned heat dissipation system. Specifically, Figure 1As shown, the heat dissipation system of this embodiment includes an air spring 1 (actually the gas chamber of the air spring 1), an air supply module 2, a first pipeline 3, a second pipeline 4, a third pipeline 5 and a fourth pipeline 6. The gas chamber of the air spring 1 is provided with an air inlet and an exhaust port. The outlet end of the air supply module 2 is connected to the air inlet of the gas chamber of the air spring 1, and the inlet end of the air supply module 2 is connected to the first pipeline 3 and the second pipeline 4; the exhaust port of the gas chamber of the air spring 1 is connected to the third pipeline 5 and the fourth pipeline 6. The air inlet of the gas chamber of the air spring 1 is provided with a first one-way valve, and the exhaust port of the gas chamber of the air spring 1 is provided with a second one-way valve. The first one-way valve allows the air supply module 2 to inject air into the gas chamber of the air spring 1, but does not allow the gas chamber of the air spring 1 to exhaust toward the air supply module 2. The second one-way valve allows the gas chamber of the air spring 1 to exhaust toward the third pipeline 5 and the fourth pipeline 6, but does not allow the gas in the third pipeline 5 and the fourth pipeline 6 to enter the gas chamber of the air spring 1.

[0067] One end of the first pipeline 3 is connected to the air outlet of the air conditioner, and the other end is connected to the air supply module 2; one end of the second pipeline 4 is connected to the external environment, and the other end is connected to the air supply module 2; one end of the third pipeline 5 is connected to the gas chamber of the air spring 1, and the other end is connected to the air inlet of the air conditioner; one end of the fourth pipeline 6 is connected to the gas chamber of the air spring 1, and the other end is connected to the external environment.

[0068] This embodiment further optimizes the above pipeline module. Specifically, Figure 1 As shown, the pipeline module includes a first connecting pipe 7 and a second connecting pipe 8. One end of the first connecting pipe 7 is connected to the inlet of the air supply module 2, and the other end is connected to the outlets of the first pipeline 3 and the second pipeline 4 through a first three-way valve 9. The first three-way valve 9 is connected to the control module for signal transmission. One end of the second connecting pipe 8 is connected to the outlet of the gas chamber of the air spring 1, and the other end is connected to the inlet of the third pipeline 5 and the fourth pipeline 6 through a second three-way valve 10. The second three-way valve 10 is connected to the control module for signal transmission.

[0069] By controlling the valve opening of the first three-way valve 9, the control module can achieve communication between the first pipeline 3 and the air supply module 2, or between the second pipeline 4 and the air supply module 2; by controlling the valve opening of the second three-way valve 10, the control module can achieve communication between the third pipeline 5 and the exhaust port of the gas chamber of the air spring 1, or between the fourth pipeline 6 and the exhaust port of the gas chamber of the air spring 1. This control method can achieve different air supply and exhaust effects.

[0070] When the control module controls the first three-way valve 9 to connect the first pipeline 3 with the air supply module 2 and disconnects the second pipeline 4 from the air supply module 2, it is equivalent to connecting the air-conditioning outlet with the air supply module 2, and the gas discharged from the air-conditioning outlet can enter the air supply module 2, and the air supply module 2 can inject the low-temperature gas discharged from the air-conditioning outlet into the gas chamber of the air spring 1, thereby achieving the effect of dissipating heat for the air spring 1; when the control module controls the first three-way valve 9 to disconnect the first pipeline 3 from the air supply module 2 and connect the second pipeline 4 with the air supply module 2, it is equivalent to connecting the external gas with the air supply module 2, and the external low-temperature gas can enter the air supply module 2, and the air supply module 2 can inject the external low-temperature gas into the gas chamber of the air spring 1, thereby achieving the effect of dissipating heat for the air spring 1.

[0071] When the control module controls the second three-way valve 10 to connect the third pipeline 5 with the exhaust port of the gas chamber of the air spring 1, and disconnects the fourth pipeline 6 from the exhaust port of the gas chamber of the air spring 1, it is equivalent to connecting the exhaust port of the gas chamber of the air spring 1 with the air inlet of the air conditioner, and the high-temperature gas discharged from the gas chamber of the air spring 1 enters the air inlet of the air conditioner, and the waste heat of the gas chamber of the air spring 1 is recovered; when the control module controls the second three-way valve 10 to disconnect the third pipeline 5 from the exhaust port of the gas chamber of the air spring 1, and connects the fourth pipeline 6 with the exhaust port of the gas chamber of the air spring 1, it is equivalent to connecting the exhaust port of the gas chamber of the air spring 1 with the external environment, and the high-temperature gas discharged from the gas chamber of the air spring 1 is directly discharged to the outside.

[0072] In some other embodiments of the present application, this embodiment optimizes the above-mentioned temperature acquisition module. Specifically, the temperature acquisition module includes a first temperature sensor 11, a second temperature sensor 12 and a third temperature sensor 13. The first temperature sensor 11 is arranged inside the air spring 1, and is used to collect the gas temperature inside the gas chamber of the air spring 1. The gas temperature inside the gas chamber of the air spring 1 collected by the first temperature sensor 11 can be used to determine whether heat is dissipated; the second temperature sensor 12 is arranged at the inlet end of the second pipeline 4, and is used to collect the external environment gas temperature. The second pipeline 4 is a pipeline structure connecting the external gas and the air supply module 2. The second temperature sensor 12 is arranged at the inlet position of the second pipeline 4, which can accurately obtain the temperature of the external gas; the third temperature sensor 13 is arranged at the air outlet of the air conditioner, and is used to collect the gas temperature at the air outlet of the air conditioner.

[0073] The temperature data collected by the first temperature sensor 11 , the second temperature sensor 12 and the third temperature sensor 13 are all transmitted to the control module, and the control module makes further judgments based on the collected temperature data.

[0074] In a preferred embodiment of the present application, the present embodiment optimizes the above-mentioned control module. Specifically, the control module includes a first judgment module, a second judgment module, a third judgment module and a fourth judgment module, and different judgment modules integrate different control functions.

[0075] The first judgment module is used to compare the internal gas temperature of the air spring 1 with the set temperature (the set temperature in this embodiment is 60℃~100℃, and is not limited to this value in actual application, and can be adjusted accordingly according to actual needs). When the internal gas temperature of the air spring 1 is not less than the set temperature, it is considered that the gas temperature in the gas chamber of the air spring 1 is too high. If it runs at this temperature for a long time, not only will the vibration reduction effect of the air spring 1 be greatly reduced, but it may also affect the service life of the air spring 1. Therefore, it is judged that the air spring 1 needs to be cooled. On the contrary, when the internal gas temperature of the air spring 1 is less than the set temperature, it is judged that the air spring 1 has no need for cooling, that is, the gas temperature in the gas chamber of the air spring 1 is appropriate at this time, and no cooling operation is required.

[0076] To determine whether the air spring 1 needs to dissipate heat, it is only necessary to determine and identify the temperature in the gas chamber of the air spring 1 , without considering other factors.

[0077] The second judgment module of this embodiment is used to compare the air conditioning outlet temperature with the external ambient air temperature when the air spring 1 has a heat dissipation demand and the air conditioner is in cooling mode. At this time, because the air conditioner is in cooling mode, the temperature of the gas discharged from the air conditioning outlet may be lower than the external air temperature after heat exchange by the air conditioning assembly. In order to further improve the heat dissipation efficiency of the air spring 1, by comparing the external air temperature and the air conditioning outlet temperature, the gas with the lower temperature of the two is selected as the heat dissipation gas source, which can achieve a better heat dissipation effect. The second judgment module makes a judgment to connect the first pipeline 3 and cut off the second pipeline 4 when the air conditioning outlet temperature is lower than the external ambient air temperature. When the air conditioning outlet temperature is not lower than the external ambient air temperature, it makes a judgment to cut off the first pipeline 3 and connect the second pipeline 4.

[0078] Specifically, when the air spring 1 needs to dissipate heat, the air conditioner is in cooling mode. If the air conditioner outlet temperature is lower than the external ambient air temperature, that is, the air conditioner outlet temperature is lower, the first pipe 3 is connected and the second pipe 4 is cut off, connecting the air conditioner outlet with the air supply module 2, cutting off the connection between the external environment and the air supply module 2, and the air supply module 2 injects air from the air conditioner outlet into the air spring 1 to discharge the high-temperature air inside the air spring 1. If the air conditioner outlet temperature is not lower than the external ambient air temperature, that is, the external air temperature is lower, the first pipe 3 is cut off and connected to the second pipe 4, connecting the external air with the air supply module 2, cutting off the connection between the air conditioner outlet and the air supply module 2, and the air supply module 2 injects low-temperature external air into the air spring 1 to discharge the high-temperature air inside the air spring 1. When the high-temperature air in the gas chamber of the air spring 1 is completely replaced by low-temperature air, and when the gas temperature in the gas chamber of the air spring 1 is lower than the set temperature, the heat dissipation of the air spring 1 is completed.

[0079] The third determination module is configured to connect the second conduit 4 and disconnect the first conduit 3 when air spring 1 requires heat dissipation and the air conditioner is in heating mode. When the air conditioner is in heating mode, the air conditioner outlet supplies warm air to the passenger compartment. At this time, the air conditioner inlet temperature is considered lower than the air conditioner outlet temperature, and the air conditioner inlet temperature is the same as the outside air temperature. Therefore, the outside air is directly used as the heat dissipation source for air spring 1. By connecting the second conduit 4 and disconnecting the first conduit 3, the outside air is connected to the air supply module 2. The air supply module 2 then injects the low-temperature outside air into the air spring 1, causing the high-temperature air inside the air spring 1 to be discharged.

[0080] The fourth judgment module is used to make a judgment on whether to connect the third pipeline 5 and cut off the fourth pipeline 6 when the air spring 1 has a heat dissipation demand and the air conditioner is in heating mode. Figure 3As shown, when the air conditioner is in heating mode, the air supply module 2 injects external air into the gas chamber of the air spring 1 for heat dissipation. The temperature of the gas discharged from the gas chamber of the air spring 1 is higher than the external gas temperature. At this time, the air conditioner has a heating demand, so it is only necessary to connect the third pipeline 5 and cut off the fourth pipeline 6, and connect the air inlet of the air conditioner with the exhaust port of the gas chamber of the air spring 1, so that the gas discharged from the gas chamber of the air spring 1 enters the air conditioner assembly through the air inlet of the air conditioner, and the waste heat of the gas in the gas chamber of the air spring 1 can be recovered, the air intake temperature of the air conditioner inlet can be increased, and the air outlet temperature of the air conditioner can be made higher, which is more conducive to the heating mode of the air conditioner. In actual application, since the temperature of the gas discharged from the gas chamber of the air spring 1 is relatively high, if it is directly discharged to places where heating is required, such as the passenger compartment and battery pack, it may cause a sharp local temperature rise and cause adverse effects. Therefore, in this embodiment, the high-temperature gas discharged from the gas chamber of the air spring 1 is discharged into the air inlet of the air conditioner. The gas entering from the air inlet of the air conditioner is heat exchanged in the air conditioning assembly, which is more gentle for the recovery of waste heat of the gas discharged from the gas chamber of the air spring 1.

[0081] When actually cooling the air spring 1 shock absorber, if Figures 2-3 As shown, the gas temperature in the air spring 1 is collected to determine whether the air spring 1 needs to be cooled. The gas temperature inside the air spring 1 is compared with the set temperature. If the gas temperature inside the air spring 1 is not less than the set temperature, the air spring 1 needs to cool. If the gas temperature inside the air spring 1 is less than the set temperature, the air spring 1 does not need to cool. If the air spring 1 needs to cool, the current air conditioning mode is obtained.

[0082] When the air conditioner is in cooling mode, the air outlet temperature of the air conditioner is compared with the external air temperature. When the air outlet temperature of the air conditioner is lower than the external ambient air temperature, the first pipeline 3 is connected and the second pipeline 4 is cut off. The air supply module 2 injects the air from the air outlet of the air conditioner into the air spring 1 to discharge the high-temperature gas inside the air spring 1. When the air outlet temperature of the air conditioner is not lower than the external ambient air temperature, the first pipeline 3 is cut off and connected to the second pipeline 4. The air supply module 2 injects external air into the air spring 1 to discharge the high-temperature gas inside the air spring 1. When the gas temperature in the gas chamber of the air spring 1 is lower than the set temperature, the air supply to the gas chamber of the air spring 1 is stopped.

[0083] When the air conditioner is in heating mode, the first pipeline 3 is cut off and connected to the second pipeline 4, and the air supply module 2 injects external air into the air spring 1 to discharge the high-temperature gas inside the air spring 1. When the gas temperature in the gas chamber of the air spring 1 is lower than the set temperature, the air supply to the gas chamber of the air spring 1 is stopped, the third pipeline 5 is connected and the fourth pipeline 6 is cut off, and the gas inside the air spring 1 is discharged to the air inlet of the air conditioner;

[0084] When there is no need to recover the waste heat of the gas inside the air spring 1 , the third pipeline 5 is cut off to connect to the fourth pipeline 6 , and the gas inside the air spring 1 is discharged to the external environment.
