Description

Technical Field

[0001] This application relates to the field of compressor technology, and in particular to an air conditioning system and vehicle. Background Technology

[0002] With increasingly stringent environmental protection requirements, the trend of using low GWP (Global Warming Potential) natural refrigerants to replace traditional refrigerants in automotive air conditioning compressors is deepening. Typical natural refrigerants include R290 (propane) and R744 (carbon dioxide). Due to its flammability and explosiveness, R290 refrigerant requires higher sealing performance from the compressor; while carbon dioxide has a much higher pressure than traditional refrigerants, thus also requiring higher sealing performance from the compressor.

[0012] In some embodiments, the sealing alarm device includes a plurality of fixed posts extending in the axial direction and spaced circumferentially around the intake pipe, each fixed post being connected to the main housing and the compressor.

[0027] With increasingly stringent environmental regulations, the trend of replacing traditional refrigerants with low GWP (Global Warming Potential) natural refrigerants in automotive air conditioning compressors is deepening. Typical natural refrigerants include R290 (propane) and R744 (carbon dioxide). R290 refrigerant, due to its flammability and explosiveness, places higher demands on the compressor's sealing performance; while carbon dioxide has a much higher pressure than traditional refrigerants, thus also requiring higher sealing performance from the compressor. Since automotive air conditioning compressors operate with the vehicle, they are continuously subjected to vibrations from the entire vehicle, which places higher demands on the compressor's sealing performance, especially at the interfaces between the compressor and other pipes in the air conditioning system. Therefore, improving the sealing performance of the air conditioning system and providing timely warnings of refrigerant leaks are urgent problems to be solved.

[0028] To address the related technical problems, this application provides a vehicle that includes the following air conditioning system.

[0029] To address the related technical problems, this application also provides an air conditioning system, for details please refer to [link / reference needed]. Figures 1 to 3 , Figure 1 This is a schematic diagram of the structure of an embodiment of the air conditioning system provided in this application; Figure 2 yes Figure 1 A disassembly diagram of one embodiment of the sealing alarm device; Figure 3 yes Figure 1 A cross-sectional view of the sealing alarm device, the air intake pipe, and the exhaust pipe along the AA direction.

[0030] The air conditioning system 10 may include a refrigeration system, which may include a compressor 100, a condenser, a receiver-drier, an expansion valve, and an evaporator. The compressor 100 is connected to the outlet of the evaporator via a return pipe. The compressor 100 compresses the low-temperature, low-pressure refrigerant into a high-temperature, high-pressure gaseous refrigerant. The compressor 100 may include an exhaust pipe 110, and the condenser may include an intake pipe 130. The exhaust pipe 110 and the intake pipe 130 are connected so that the condenser can receive the high-temperature, high-pressure gaseous refrigerant discharged by the compressor 100 through the intake pipe 130. The high-temperature, high-pressure gaseous refrigerant flows in the condenser and releases heat, thereby converting into a medium-temperature, high-pressure liquid refrigerant. The condenser is connected to the receiver-drier via a pipe to dry the refrigerant. The expansion valve is connected to the receiver-drier via a pipe, thereby throttling and depressurizing the medium-temperature, high-pressure liquid refrigerant into a low-temperature, low-pressure mist, which is then sprayed into the evaporator. The low-temperature, low-pressure mist refrigerant absorbs heat and vaporizes in the evaporator, thereby reducing the air temperature inside the vehicle.

[0031] Because the various components between the compressor 100 and the evaporator are connected by pipes, and the refrigerant is under high pressure in most of these components, there is a risk of refrigerant leakage at the connection points of the two pipes.

[0032] The sealing alarm device 200 can be installed at the connection between the exhaust pipe 110 of the compressor 100 and the inlet pipe 130 of the condenser. However, this application does not limit the sealing alarm device 200 to only being installed at the connection between the exhaust pipe 110 and the inlet pipe 130 of the condenser. In some other embodiments, the sealing alarm device 200 can also be installed at the connection between the condenser and the liquid receiver dryer; or at the connection between the liquid receiver dryer and the expansion valve, etc. Specifically, the sealing alarm device 200 may include a first elastic sealing cover 210, a push rod 220, and a trigger assembly 230. The first elastic sealing cover 210 is an elastic body structure, and its two ends are respectively sleeved on the outer periphery of the exhaust pipe 110 and the inlet pipe 130, thereby forming a first gas storage space 211 between the first elastic sealing cover 210, the exhaust pipe 110, and the inlet pipe 130. When refrigerant leaks from the connection between the intake pipe 130 and the exhaust pipe 110 and enters the first gas storage space 211, the refrigerant accumulation in the first gas storage space 211 causes the first elastic sealing cover 210 to expand. A push rod 220 is connected to the side of the first elastic sealing cover 210 opposite to the first gas storage space 211, so that the expansion force of the first elastic sealing cover 210 can be transmitted by pushing the push rod 220. A trigger assembly 230 is spaced apart from the push rod 220 along the movement path of the push rod 220, so that the trigger assembly 230 maintains a preset distance from the push rod 220 when the first elastic sealing cover 210 is not expanded. When the push rod 220 is pushed by the first elastic sealing cover 210 to the trigger position of the trigger assembly 230, the trigger assembly 230 is activated. The trigger assembly 230 can be used to issue an alarm signal, thereby alerting the user to the refrigerant leak.

[0033] The first elastic sealing cover 210 can be made of rubber, such as silicone rubber, fluororubber, or fluorosilicone rubber, to provide excellent elasticity and oil resistance. The push rod 220 can be made of aluminum alloy to ensure lightweight and rigidity. The triggering component 230 can include devices such as a piezoresistor, sensor, or microswitch to achieve precise triggering. The first elastic sealing cover 210 provides buffering through refrigerant fluid accumulation, reducing the risk of direct refrigerant leakage, while also ensuring the stability of the push rod 220's movement path. Understandably, before the first elastic sealing cover 210 is fitted around the periphery of the pipeline, the radial dimensions at both ends of the first elastic sealing cover 210 are smaller than the radial dimensions of the pipeline, so that the two ends of the first elastic sealing cover 210 deform to fit around the periphery of the pipeline, thereby allowing the first elastic sealing cover 210 to expand and accommodate the refrigerant.

[0034] Through the above implementation, the first elastic sealing cover 210 forms a first gas storage space 211 at the connection between the exhaust pipe 110 and the intake pipe 130. This allows gas to first accumulate inside the first elastic sealing cover 210 when refrigerant leaks, effectively buffering the leakage process and preventing direct escape into the external environment, thus reducing the safety risk caused by instantaneous leakage of flammable and explosive refrigerant. The expansion of the first elastic sealing cover 210 pushes the push rod 220 to contact the trigger component 230, which immediately sends an alarm signal. This not only improves the sealing performance of the compressor 100 but also provides timely alarms, enhancing the safety and reliability of the air conditioning system 10.

[0035] In some embodiments, the sealing alarm device 200 includes a second elastic sealing cover 240, which is located within the first air storage space 211 and sleeved at the connection between the air inlet pipe 130 and the exhaust pipe 110 to form a second air storage space 241 between the second elastic sealing cover 240, the air inlet pipe 130 and the exhaust pipe 110. The dimension of the second elastic sealing cover 240 in the axial direction of the exhaust pipe 110 is smaller than the dimension of the first elastic sealing cover 210 in the axial direction. The second elastic sealing cover 240 corresponds to the push rod 220 in the radial direction of the exhaust pipe 110.

[0036] The second elastic sealing cover 240, as a sealing component, is located inside the first gas storage space 211. Both ends of the second elastic sealing cover 240 are respectively fitted around the outer periphery of the inlet pipe 130 and the exhaust pipe 110, thereby forming a second gas storage space 241 between the second elastic sealing cover 240, the inlet pipe 130, and the exhaust pipe 110. The connection between the inlet pipe 130 and the exhaust pipe 110 is located within the second gas storage space 241, allowing the second gas storage space 241 to store refrigerant leaking from the connection between the inlet pipe 130 and the exhaust pipe 110. Furthermore, the dimension of the second elastic sealing cover 240 in the axial direction of the exhaust pipe 110 is smaller than that of the first elastic sealing cover 210. This allows the second elastic sealing cover 240 to undergo elastic deformation more rapidly when refrigerant leakage causes an increase in pressure in the second gas storage space 241, reducing expansion delay. The second elastic sealing cover 240 is also correspondingly provided with the push rod 220 in the radial direction of the exhaust pipe 110, ensuring that the expansion force of the second elastic sealing cover 240 can be directly transmitted to the push rod 220, reducing the risk of the push rod 220 shifting or losing energy during movement. The second elastic sealing cover 240 can be made of highly elastic silicone or fluororubber material to provide good deformation capacity and oil resistance. When the seal of the second elastic sealing cover 240 fails, refrigerant can enter the first gas storage space 211 from the second gas storage space 241.

[0037] Therefore, the axial dimension of the second elastic sealing cover 240 is smaller than that of the first elastic sealing cover 210, thereby shortening the alarm response time. The second elastic sealing cover 240 precisely corresponds to the push rod 220 in the radial direction, improving the reliability of triggering and reducing the risk of false alarms or missed alarms. The second elastic sealing cover 240, disposed within the first elastic sealing cover 210, also provides double-layer protection for the sealing of the sealing alarm device 200, improving the sealing effect of the sealing alarm device 200 as well as the timeliness and accuracy of the alarm.

[0038] See Figure 4 , Figure 4 yes Figure 3 An enlarged structural diagram at the dashed box O.

[0039] In some embodiments, the second elastic sealing cover 240 includes a main body 243 and at least one arc-shaped sealing part 242. The at least one arc-shaped sealing part 242 is connected to one end of the main body 243 in the axial direction. The end of the arc-shaped sealing part 242 away from the main body 243 is sleeved on the outer periphery of the air inlet pipe 130 or the exhaust pipe 110. The arc center of the arc-shaped sealing part 242 is located on the side away from the second air storage space 241.

[0040] Both the main body 243 and the arc-shaped sealing portion 242 are annular and connected in the axial direction. As an example, the second elastic sealing cover 240 may include a main body 243 and an arc-shaped sealing portion 242, with the arc-shaped sealing portion 242 connected to the end of the main body 243 in the axial direction near the intake pipe 130 or the exhaust pipe 110. For example, if the arc-shaped sealing portion 242 is connected to the end of the main body 243 near the intake pipe 130, then one end of the main body 243 is fitted around the outer periphery of the exhaust pipe 110, and the end of the arc-shaped sealing portion 242 away from the main body 243 is fitted around the outer periphery of the intake pipe 130. As another example, the second elastic sealing cover 240 may include a main body 243 and two arc-shaped sealing portions 242, with the two arc-shaped sealing portions 242 connected to both ends of the main body 243 in the axial direction, and the ends of the two arc-shaped sealing portions 242 away from the main body 243 respectively fitted around the outer periphery of the intake pipe 130 and the exhaust pipe 110. Furthermore, the arc center of the arc-shaped sealing portion 242 faces away from the second gas storage space 241. Thus, the main body 243 is connected to the pipeline via at least one arc-shaped sealing portion 242, and the arc center of the arc-shaped sealing portion 242 faces away from the second gas storage space 241, thereby forming a gap between the arc-shaped sealing portion 242 and the pipeline. When refrigerant enters and expands inside the second elastic sealing cover 240, the refrigerant pushes up the gap between the arc-shaped sealing portion 242 and the pipeline. After reaching a certain threshold inside the second gas storage space 241, the refrigerant leaks from this gap into the first gas storage space 211, allowing the first elastic sealing cover 210 to buffer the refrigerant leakage and providing more maintenance time for the air conditioning system 10. The design of the arc-shaped sealing portion 242 allows the second elastic sealing cover 240 to store refrigerant and expand, and also serves as a refrigerant drainage mechanism, further facilitating the leakage of refrigerant from the arc-shaped sealing portion 242 into the first gas storage space 211. This reduces the risk of the second elastic seal 240 rupturing due to excessive internal pressure.

[0041] In some embodiments, the sealing alarm device 200 includes a sealing shell 250, which includes a main shell 251. The main shell 251 is sleeved at the connection between the air inlet pipe 130 and the exhaust pipe 110 to form a third air storage space 252 between the main shell 251, the air inlet pipe 130 and the exhaust pipe 110. The first elastic sealing cover 210 is located in the third air storage space 252.

[0042] The sealing housing 250 can be made of stainless steel or engineering plastic to ensure structural strength and corrosion resistance. The sealing housing 250 includes a main housing 251, which, along with the intake pipe 130 and exhaust pipe 110, forms a third gas storage space 252. A first elastic sealing cover 210 is located within the third gas storage space 252. Thus, the main housing 251 can limit the expansion of the first elastic sealing cover 210, thereby restricting its excessive expansion. Furthermore, if the first elastic sealing cover 210 fails to seal due to excessive expansion, refrigerant can still enter the third gas storage space 252 formed by the main housing 251, providing a buffer time for maintenance of the air conditioning system 10 and effectively reducing the risk of refrigerant leakage into the external space, thereby improving the safety and reliability of the sealing alarm device 200.

[0043] In some embodiments, the main housing 251 has a clearance hole on one side wall corresponding to the push rod 220 for avoiding the push rod 220. The clearance hole is connected to the third gas storage space 252. Part of the push rod 220 is inserted into the clearance hole, and the triggering component 230 is located on the side of the clearance hole away from the third gas storage space 252.

[0044] An clearance hole is located on the side wall of the main housing 251 corresponding to the push rod 220, allowing the push rod 220 to move smoothly without mechanical interference when the first elastic sealing cover 210 expands. The clearance hole communicates with the third gas storage space 252 so that the push rod 220 can be inserted into the clearance hole. The triggering component 230 is located on the side of the clearance hole away from the third gas storage space 252, thereby ensuring the smooth movement of the push rod 220. Thus, the clearance hole design reduces the risk of the push rod 220 getting stuck during movement, improves the response speed and reliability of the alarm trigger, and ensures that the thrust generated by the expansion of the first elastic sealing cover 210 can immediately and accurately trigger the alarm component by pushing it up. In this embodiment, the clearance hole can be designed as a circle, and the push rod 220 can be cylindrical. The radial dimension of the clearance hole can be slightly larger than the radial dimension of the push rod 220, thereby reducing the contact area between the clearance hole and the push rod 220, reducing the friction between the push rod 220 and the clearance hole, and making it easier for the push rod 220 to move, so that the triggering component 230 can be triggered more quickly.

[0045] In some embodiments, the main housing 251 includes a first sub-housing and a second sub-housing, which are disposed opposite to each other, thereby clamping the intake pipe 130 and the exhaust pipe 110 between the first and second sub-housing, facilitating the installation of the sealing shell 250. Furthermore, sealing rings may be provided at the connections between the first and second sub-housing and the intake pipe 130 and the exhaust pipe 110 to improve the sealing effect of the main housing 251. One of the first and second sub-housing may also have a retaining protrusion, and the other may have a retaining ring, thereby tightly fixing the first and second sub-housing together and further improving the sealing effect of the sealing shell 250.

[0046] In some embodiments, the sealing shell 250 includes a secondary shell 253, which covers the side of the clearance hole away from the third gas storage space 252 to form an accommodating space 2531 with the side wall of the main shell 251. The triggering component 230 is located in the accommodating space 2531 and is installed on an inner side wall of the secondary shell 253 that is spaced apart from the clearance hole.

[0047] The secondary housing 253 forms a closed space on the side of the clearance hole away from the third gas storage space 252, together with the outer wall of the main housing 251, to form a receiving space 2531 to accommodate the trigger assembly 230. The trigger assembly 230 is installed on an inner side wall of the secondary housing 253, which is spaced apart from the clearance hole, allowing the push rod 220 to accurately contact the trigger assembly 230. Thus, by covering the clearance hole on the side of the clearance hole away from the third gas storage space 252 with the secondary housing 253 to form the receiving space 2531, the position of the trigger assembly 230 is fixed and stable, effectively reducing the risk of false triggering of the trigger assembly 230 due to continuous vibration of the compressor 100. At the same time, the receiving space 2531 isolates external environmental factors, preventing dust and moisture from entering the trigger assembly 230, extending the service life of the equipment, and ensuring that the alarm signal can be triggered in a timely and accurate manner in case of refrigerant leakage.

[0048] In some embodiments, the sealing alarm device 200 includes an arc-shaped plate 260, which is disposed on the side of the first elastic sealing cover 210 near the push rod 220. The side of the arc-shaped plate 260 away from the first elastic sealing cover 210 is connected to the push rod 220, and the cross-sectional radius of the arc-shaped plate 260 is larger than the cross-sectional radius of the first elastic sealing cover 210.

[0049] The arc-shaped plate 260 is a curved guide structure with a cross-sectional radius larger than that of the first elastic sealing cover 210. This allows the contact area between the first elastic sealing cover 210 and the arc-shaped plate 260 to gradually increase as the first elastic sealing cover 210 expands due to refrigerant leakage. The arc-shaped plate 260 can more smoothly guide the push rod 220 in the radial direction, reducing the risk of push rod 220 deviating. The side of the arc-shaped plate 260 facing away from the first elastic sealing cover 210 is directly connected to the push rod 220, allowing the expansion force to be efficiently transmitted to the push rod 220 and reducing vibration interference. The arc-shaped plate 260 can be made of a rubber material with a certain degree of hardness, enabling it to both support the movement of the push rod 220 and possess a certain deformation capacity to adapt to the deformation of the first elastic sealing cover 210. Therefore, the push rod 220 can move more stably and smoothly, significantly reducing the triggering delay of the triggering component 230 and the probability of accidental activation.

[0050] In some embodiments, the arc-shaped plate 260 is connected to the first elastic sealing cover 210 through multiple connection points spaced apart in the axial direction. The first elastic sealing cover 210 includes multiple bending deformation portions spaced apart in the axial direction, with each bending deformation portion located between two connection points. When the first elastic sealing cover 210 is not expanded, the bending deformation portions are in a bent and folded state. When the first elastic sealing cover 210 expands, the bending deformation portions gradually become stretched. The arc-shaped plate 260 has both a certain degree of hardness and a certain degree of deformation capacity, allowing it to adapt to the deformation of the bending deformation portions. Thus, the arc-shaped plate 260 can both push the push rod 220 due to the expansion of the first elastic sealing cover 210 and maintain a stable connection with the first elastic sealing cover 210, reducing the risk of displacement of the arc-shaped plate 260 due to unstable connection with the first elastic sealing cover 210, thereby causing the push rod 220 to shift.

[0051] In some embodiments, the sealing alarm device 200 includes a plurality of fixing posts 270, which extend in the axial direction and are circumferentially spaced around the air intake pipe 130. Each fixing post 270 is connected to the main housing 251 and the compressor 100.

[0052] The fixing post 270 provides mechanical support to ensure the sealing alarm device 200 is securely installed under the vibration of the compressor 100. The fixing post 270 can be made of stainless steel or aluminum alloy to enhance its strength. The number of fixing posts 270 can be two, three, or four. For example, four fixing posts 270 are evenly distributed circumferentially along the intake pipe 130 to optimize force balance. The end of the fixing post 270 near the compressor 100 may have an external thread, and the housing of the compressor 100 may have a threaded hole with an internal thread. Each fixing post 270 is connected to the main housing 251 and can be fixed to the housing of the compressor 100 via the external thread. Thus, the sealing shell 250 can be stably fixed to the compressor 100 by the fixing post 270, thereby limiting the rotation of the sealing shell 250 in the circumferential direction and reducing the risk of misalignment between the sealing shell 250 and the push rod 220 or interference between the sealing shell 250 and the push rod 220, which could lead to the triggering component 230 failing to be stably triggered.

[0053] In some embodiments, each fixing post 270 includes a fixing head 271 and a post body 272. The outer periphery of the exhaust pipe 110 is provided with an annular protrusion 120. The post body 272 penetrates the main housing 251 and is connected to the outer casing of the compressor 100. The fixing head 271 abuts against the side of the main housing 251 opposite to the exhaust pipe 110, and the annular protrusion 120 abuts against the side of the main housing 251 opposite to the fixing head 271.

[0054] A fixing head 271 is connected to one end of a column 272. The end of the column 272 away from the fixing head 271 can penetrate two relatively spaced side walls of the main housing 251 and connect to the outer casing of the compressor 100. The exhaust pipe 110 includes an annular protrusion 120, which is disposed on the outer periphery of the exhaust pipe 110. The fixing head 271 and the annular protrusion 120 are spaced apart in the axial direction. The fixing head 271 abuts against the side of the main housing 251 opposite to the compressor 100, and the annular protrusion 120 abuts against the side of the main housing 251 opposite to the fixing head 271. This clamps the main housing 251 between the annular protrusion 120 and the fixing head 271, effectively preventing the sealing alarm device 200 from shifting in the axial direction. It also reduces the risk of misalignment between the sealing housing 250 and the push rod 220 in the axial direction. This allows the sealing alarm device 200 to be stably installed at the connection between the intake pipe 130 and the exhaust pipe 110, and also reduces the risk that the triggering component 230 may not respond in time due to misalignment of the sealing shell 250 and the push rod 220.

[0055] Of course, in some other embodiments, an annular groove may also be provided on the outer periphery of the exhaust pipe 110. The annular groove is arranged around the circumference of the exhaust pipe 110, and the end of the main housing 251 near the compressor 100 is confined within the annular groove, thereby achieving the purpose of limiting the sealing alarm device 200 in the axial direction. This reduces the risk that the triggering component 230 may not respond in time due to misalignment between the sealing housing 250 and the push rod 220.

[0056] In some embodiments, the air conditioning system 10 further includes a control component, which can be used to receive alarm signals from the sealing alarm device 200 and control the operation of the compressor 100. When refrigerant leaks, the trigger component 230 sends an alarm signal, and the control component receives the alarm signal to send a command to stop the compressor 100, thereby reducing the risk of continuous refrigerant leakage. The vehicle also includes a vehicle infotainment system, which can also be used to receive alarm signals from the sealing alarm device 200. After receiving the alarm signal, the vehicle infotainment system can issue a refrigerant leak warning to alert the user. The vehicle infotainment system can also be connected to the control component, so that the vehicle infotainment system can send a command to the control component to shut down the compressor 100, thereby achieving the stopping or starting of the compressor through the vehicle infotainment system.

[0057] In some embodiments, the trigger component 230 may include an electrically connected trigger element and a signal transmission element. The trigger element may be a varistor, sensor, or microswitch, and the signal transmission element may be a transmission line or a wireless transmitter. For example, the trigger element is a microswitch, and the signal transmission element is a transmission line. When the push rod 220 contacts the microswitch, the transmission line forms a conductive circuit. The transmission line can also be connected to the vehicle infotainment system to transmit the alarm signal. The use of a microswitch and transmission line makes signal transmission more stable, reduces the failure rate of the trigger component 230, and lowers the risk of refrigerant leakage due to trigger component 230 failure, thus preventing the timely transmission of alarm signals.

[0058] In some embodiments, the sealing alarm device 200 further includes an elastic recovery element located between the arc plate 260 and the main housing 251. The elastic recovery element can be an elastic component such as a spring or a sheet. When the first elastic sealing cover 210 expands due to refrigerant leakage, causing the arc plate 260 and the push rod 220 to move toward the trigger assembly 230 in sequence, the elastic recovery element is in a compressed state. After the refrigerant leakage is repaired, the first elastic sealing cover 210 loses its expansion force, and the elastic recovery element can restore the first elastic sealing cover 210 to its unexpanded state through the arc plate 260.

[0059] In summary, the first elastic sealing cover 210 forms a first gas storage space 211 at the connection between the exhaust pipe 110 and the intake pipe 130. This allows gas to accumulate inside the first elastic sealing cover 210 when refrigerant leaks, effectively buffering the leakage process and preventing direct escape into the external environment, thus reducing the safety risks caused by the instantaneous leakage of flammable and explosive refrigerant. The expansion of the first elastic sealing cover 210 pushes the push rod 220 to contact the trigger component 230, which immediately sends an alarm signal. This not only improves the sealing performance of the compressor 100 but also provides timely alarm, enhancing the safety and reliability of the air conditioning system 10.
