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 absorber is an important part of automobile suspension system, and its main function is to buffer the impact of the ground on the vehicle and improve the comfort and handling of the vehicle. Shock absorber with air spring (air spring) is widely used in the current automobile field. Generally, shock absorber with air spring includes air spring and height sensor. The air spring is arranged between the vehicle body and the spring tray on the suspension, and has the functions of buffering and vibration reduction. There are two height sensors, and the two height sensors can be arranged on the frame and the spring tray respectively, or, respectively arranged on the frame and the upper swing arm or respectively arranged on the frame and the lower swing arm. The height sensor is used to detect the height signal of the vehicle and transmit the height signal to the electronic control unit (Electronic Control Unit, ECU), and the ECU can adjust the posture of the vehicle body according to the read height signal. The ECU adjusts the posture of the vehicle body according to the read height signal and the vehicle state, and when the posture of the vehicle body is adjusted, the ECU can start the air supply and distribution module to realize the gas transmission between the air storage tank and the air spring. Among them, the air supply and distribution module can be an air compressor, etc.

[0003] During the driving process of the vehicle, the temperature of the air in the air spring chamber rises due to the frequent compression of the air. When the temperature is too high, it will affect the performance of the air spring and reduce the comfort of the vehicle during driving. In order to solve this technical problem, the prior art proposes an air supply device for air suspension, in which the air supply device includes an air pump, and the air drying chamber is used to dry the gas compressed by the air pump. A motor for driving the air pump is provided on the outside of the air supply device. The air pump is independently arranged and connected to the reversing valve device or the air drying chamber 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 use effect 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 the cooling effect on the gas entering the air spring is poor. Furthermore, the heat generated after the air spring is compressed is a harmful heat source for the air spring itself, but for other structures on the car, this heat source can be used, but this is not involved in the current existing technology, resulting in energy waste.

[0035] The advantages of the present application are as follows: 1. The air spring damper heat dissipation system of the present application introduces four pipeline structures and an air supply module, two pipelines are respectively connected to the air outlet of the air conditioner, the external environment and the air supply module, and the air supply module can select the air with lower temperature to supply to the air spring according to the comparison between the air outlet temperature of the air conditioner and the external air temperature, so that the internal air temperature of the air spring drops rapidly, and the heat dissipation effect of the air spring is excellent, and the air spring can always be maintained in a good use condition, thereby extending 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 inlet of the air conditioner The air spring is connected to the external environment, and can selectively recover the heat energy of the high-temperature gas inside the air spring when the air spring is in the heat dissipation mode. The high-temperature gas discharged from the air spring can be introduced into the air inlet of the air conditioner, so that the temperature entering the air inlet of the air conditioner is greatly increased, and the heating efficiency of the air conditioner is improved, which can save heating energy in the low temperature condition in winter. In addition, the present application only adds four pipeline structures, the improvement is very small, the cost is extremely low, and it will not occupy too much space, and there is no need to configure special cooling equipment. The entire operation control method is also extremely simple, and the cost of use is low, which is suitable for large-scale promotion and application.

[0036] 2. The present application adds a first temperature sensor inside the air spring, and the first temperature sensor can directly obtain the temperature of the gas inside the air spring. The obtained temperature more intuitively reflects the temperature inside the air spring, and the subsequent adjustment and control of the air spring is more accurate; a temperature sensor is set at the inlet end of the second pipeline and the air outlet of the air conditioner, which can directly obtain the external environment gas temperature and the air outlet temperature of the air conditioner, and can screen out the gas temperature with a lower temperature, so as to facilitate the rapid cooling and adjustment of the gas inside the air spring, and to facilitate the judgment of whether waste heat recovery is needed, so that 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 pipeline and the second pipeline, and uses a first three-way valve on the first connecting pipe to control the on-off of the first pipeline and the second pipeline, which can greatly reduce the complexity of the entire pipeline 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 a small space, further reducing the cost and use cost;

[0038] 4. The present application sets a second connecting pipe between the third pipeline and the fourth pipeline, and uses the second three-way valve on the second connecting pipe to control the on-off of the third pipeline and the fourth pipeline, which can greatly reduce the complexity of the entire pipeline structure, facilitate the control and adjustment of the exhaust of the air spring, and the exhaust control circuit of the air spring is easy to arrange and occupies a small space, further reducing the cost and use cost;

[0039] 5. This application compares the internal gas temperature of the air spring with the set temperature to determine whether the air spring needs to be cooled, which is actually to provide 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, and can accurately determine whether it is necessary to provide low-temperature gas to the air spring, thereby improving the use effect and service life of the air spring;

[0040] 6. When the air spring has a heat dissipation demand 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 outlet temperature of the air conditioner with the temperature of the external ambient gas, so as to provide the air supply module with gas at a lower temperature 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 demand and the air conditioner is in heating mode, the external gas 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 conditioning module is in heating mode, the gas at the air outlet of the air conditioner is no longer suitable for supplying to the air spring. Therefore, the external gas 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 heat dissipation demand and the air conditioner is in heating mode, the air supply module injects external air into the air spring to discharge the high-temperature gas inside the air spring. The temperature of the discharged high-temperature gas is much higher than the external gas 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 a heat dissipation method for an air spring shock absorber. The heat dissipation method for an air spring shock absorber of the present application is very simple and has multiple functions. First, it can determine whether it is necessary to dissipate heat for the air spring. Second, when it is necessary to dissipate heat for the air spring and the air conditioner is in cooling mode, it can determine which gas to use to dissipate heat for the air spring. Third, when it is necessary to dissipate heat for the air spring and the air conditioner is in heating mode, it can quickly determine the source of gas for dissipating heat for the air spring, and recover waste heat from the exhaust gas from the air spring. The entire heat dissipation method is simple and efficient, and has extremely high heat dissipation efficiency for the air spring. 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 can save heating energy in low temperature conditions in winter.

[0044] The present application is applied to the heat dissipation of the air spring shock absorber, and has a very high heat dissipation efficiency for the air spring, which can always maintain the air spring in a good use condition and extend the service life of the air spring; and when there is a need for heating in winter, the heating efficiency of the air conditioner is improved, and the energy consumption for heating in winter can be reduced under low temperature conditions in winter.

Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of this application, the meaning of "plurality" is at least two, such as two, three, etc., unless otherwise clearly and specifically defined.

[0052] The present application is further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0053] The present application relates to a heat dissipation system for an air spring shock absorber. The heat dissipation system of the present application can automatically judge the use of the air spring and judge 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, so that the high-temperature air in the gas chamber of the air spring is discharged, so that the air spring can quickly achieve the effect of heat dissipation and cooling. The air spring can always be maintained in a good use condition, which greatly extends the service life of the air spring and ensures that the air spring always has a good application effect. The present application has two sources of low-temperature gas for the heat dissipation of the air spring, one is the air outlet of the air conditioner in the cooling mode, and the other is the external gas. The present application detects these two gases. By selecting the gas with a lower gas temperature as the gas source, the air spring can be cooled more efficiently, and the overall control method is very simple. When the air conditioner is in the heating mode, the gas at the air outlet of the air conditioner is no longer used as the heat dissipation gas, but the external gas is directly used as the heat dissipation gas, and the waste heat of the high-temperature gas discharged by the air spring is recovered, and every heat source is used for winter heating to the maximum extent, which can effectively reduce the energy consumption of winter heating.

[0054] Specifically, 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, and 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, and 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 gas temperature of the air spring 1, the external environment gas temperature and the air temperature of the air conditioner outlet. By obtaining the internal gas temperature of the air spring 1, it can be determined whether the air spring 1 needs to be cooled. By comparing the external environment gas temperature with the air conditioner outlet temperature, it can be determined 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 conditioning outlet temperature is the same as the air inlet temperature, that is, the external ambient gas temperature is consistent with the air conditioning outlet temperature. These situations are not within the scope of discussion of this application. This application only discusses the situations where the air conditioning outlet 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 demand, 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 provided 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 a 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. An air inlet and an exhaust port are arranged on the gas chamber of the air spring 1. One end of the outlet of the air supply module 2 is connected to the air inlet of the gas chamber of the air spring 1, and one end of the inlet 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. A first one-way valve is arranged at the air inlet of the gas chamber of the air spring 1, and a second one-way valve is arranged at the exhaust port of the gas chamber of the air spring 1. The first one-way valve allows the air supply module 2 to inject air into the gas chamber of the air spring 1, and does not allow the gas chamber of the air spring 1 to exhaust to the air supply module 2. The second one-way valve allows the gas chamber of the air spring 1 to exhaust to the third pipeline 5 and the fourth pipeline 6, and 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 end of the air supply module 2, and the other end is connected to the outlet ends 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 signal. One end of the second connecting pipe 8 is connected to the outlet end of the gas chamber of the air spring 1, and the other end is connected to the inlet ends 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 signal.

[0069] The control module can achieve the connection between the first pipeline 3 and the air supply module 2 or the connection between the second pipeline 4 and the air supply module 2 by controlling the valve port of the first three-way valve 9; the control module can achieve the connection between the third pipeline 5 and the exhaust port of the gas chamber of the air spring 1 or the connection between the fourth pipeline 6 and the exhaust port of the gas chamber of the air spring 1 by controlling the valve port of the second three-way valve 10. Different air supply and exhaust effects can be achieved through this control method.

[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 disconnect 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, so as to achieve the effect of heat dissipation of the air spring 1; when the control module controls the first three-way valve 9 to disconnect the first pipeline 3 with 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, so as to achieve the effect of heat dissipation of 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 to recover the waste heat of the gas chamber of the air spring 1; 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 connect 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 of 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°C to 100°C, 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 the vibration reduction effect of the air spring 1 will be greatly reduced, but also the service life of the air spring 1 may be affected. 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 cooling demand, 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 environment gas 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 gas 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 gas 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 environment gas temperature, and makes a judgment to cut off the first pipeline 3 and connect the second pipeline 4 when the air conditioning outlet temperature is not lower than the external environment gas temperature.

[0078] Specifically, when the air spring 1 has a heat dissipation demand, the air conditioner is in cooling mode at this time. If the air outlet temperature of the air conditioner is lower than the temperature of the external environment gas, that is, the air outlet temperature of the air conditioner is lower, the first pipeline 3 is connected and the second pipeline 4 is cut off, the air outlet of the air conditioner is connected with the air supply module 2, the connection between the external environment and the air supply module 2 is cut off, and 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; if the air outlet temperature of the air conditioner is not lower than the temperature of the external environment gas, that is, the external gas temperature is lower at this time, the first pipeline 3 is cut off and connected to the second pipeline 4, the external gas is connected with the air supply module 2, the connection between the air outlet of the air conditioner and the air supply module 2 is cut off, and the air supply module 2 injects the external low-temperature gas into the air spring 1 to discharge the high-temperature gas inside the air spring 1. When the high-temperature gas in the gas chamber of the air spring 1 is completely replaced by the low-temperature gas, 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 judgment module is used to make a judgment to connect the second pipeline 4 and cut off the first pipeline 3 when the air spring 1 has a heat dissipation demand and the air conditioner is in heating mode. When the air conditioner is in heating mode, the air outlet of the air conditioner provides warm air to the passenger compartment. At this time, it is considered that the temperature of the air inlet of the air conditioner is lower than the temperature of the air outlet of the air conditioner. The temperature of the air inlet of the air conditioner is the same as the temperature of the external air. Therefore, the external air is directly used as the heat dissipation gas source of the air spring 1. By connecting the second pipeline 4 and cutting off the first pipeline 3, the external air is connected to the air supply module 2. The air supply module 2 injects the external low-temperature gas into the air spring 1 to discharge the high-temperature gas inside the air spring 1.

[0080] The fourth judgment module is used to make a judgment on connecting the third pipeline 5 and cutting off the fourth pipeline 6 when the air spring 1 has a heat dissipation demand and the air conditioner is in the heating mode. Figure 3As shown, when the air conditioner is in heating mode, the air supply module 2 injects external gas 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 needs to heat up. Therefore, 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. The gas discharged from the gas chamber of the air spring 1 enters the air conditioning assembly through the air inlet of the air conditioner. 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 inlet of the air conditioner 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 the passenger compartment, battery pack and other places where heating is required, it may cause adverse effects due to drastic local temperature rise. 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, and 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 waste heat recovery of the gas discharged from the gas chamber of the air spring 1.

[0081] When actually cooling the air spring 1 shock absorber, 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 has a cooling demand. If the gas temperature inside the air spring 1 is less than the set temperature, the air spring 1 has no cooling demand. If the air spring 1 has a cooling demand, 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 gas temperature, the first pipeline 3 is connected and the second pipeline 4 is cut off, and 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 gas temperature, 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, until the gas temperature in the gas chamber of the air spring 1 is lower than the set temperature, and the gas 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 to connect 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, until the gas temperature in the gas chamber of the air spring 1 is lower than the set temperature, and the gas 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.
