It includes a pipeline interface mechanism, which is installed at the end of the condenser body. The pipeline interface mechanism includes a connecting mechanism, a pipe connecting structure and a backup conveying mechanism.

Description

Technical Field

[0001] The invention relates to the technical field of condenser interfaces, and in particular to a condenser pipeline interface structure. Background Art

[0002] Air conditioning is a device used to adjust indoor temperature, humidity and air quality. In the air conditioning system, it mainly includes four key components: compressor, condenser, throttling device and evaporator;

[0003] Air conditioning operation is based on the principle of refrigeration cycle. The compressor compresses low-temperature, low-pressure refrigerant gas into high-temperature, high-pressure gas. After entering the condenser, it exchanges heat with the air through air cooling and condenses into high-temperature, high-pressure liquid. The liquid is converted into a low-temperature, low-pressure liquid-gas mixture through the throttling device and enters the evaporator to absorb indoor heat, lowering the indoor temperature. At the same time, the refrigerant evaporates into low-temperature, low-pressure gas and returns to the compressor, completing the refrigeration cycle.

[0004] However, the compressor and condenser are two independent components. The connection between the compressor tube and the condenser tube requires the use of an interface pipe. The gas transmitted here is high-temperature and high-pressure gas. Since the interface pipe is subjected to high temperature and high pressure for a long time, it is easily damaged by high pressure, resulting in leakage. However, since the air-conditioning system is in continuous operation, even if the interface pipe leaks, the amount of gas leaked is relatively limited and difficult to detect in time. This makes it difficult for people to quickly determine whether the problem is at the interface when the air conditioner fails. This situation not only increases the difficulty and cost of maintenance, but may also cause the performance of the air-conditioning system to decline.

[0005] In view of this, we propose a condenser piping interface structure. Summary of the invention

[0006] The object of the present invention is to provide a condenser pipeline interface structure to solve the problems raised in the above background technology.

[0007] To achieve the above object, the present invention provides a condenser pipeline interface structure, including a pipeline interface mechanism, the pipeline interface mechanism is installed at the end of the condenser body, the condenser body includes a mounting frame and an air-cooling fan, the air-cooling fan is installed on the surface of the mounting frame, the mounting frame is internally connected with a condenser tube for heat exchange of refrigerant, the two ends of the condenser tube are respectively an inlet tube and an outlet tube, the pipeline interface mechanism is used to connect the inlet tube with the compressor tube, and can transport the high-temperature and high-pressure gas compressed by the compressor to the inside of the condenser body for heat exchange;

[0008] The pipeline interface mechanism includes a connecting mechanism, a connecting pipe structure and a backup conveying mechanism. The connecting pipe structure and the backup conveying mechanism are both located inside the connecting mechanism. When the connecting pipe structure is normal and leak-free, the connecting pipe structure can flexibly and pressure-resistantly convey the high-temperature and high-pressure gas. The backup conveying mechanism is used to improve the sealing performance of the pipeline interface mechanism.

[0009] When the internal part of the take-over structure is damaged and leaks, the high-temperature and high-pressure gas can be transported through the backup transport mechanism. At the same time, the internal transmission gas of the backup transport mechanism causes its surface to expand and deform, which can indicate the leakage.

[0010] As a further improvement of the present technical solution, the connecting mechanism includes a first connecting pipe and a second connecting pipe, the first connecting pipe and the second connecting pipe are threadedly connected to the inlet pipe and the compressor pipe respectively, and the inner walls of the first connecting pipe and the second connecting pipe are both paved with elastic inner walls.

[0011] As a further improvement of the present technical solution, the backup conveying mechanism includes a sealing ring gasket fixedly connected to the bottom of the first connecting tube, the sealing ring gasket can wrap the lower end surface of the first connecting tube, a middle cavity is opened inside the sealing ring gasket, and a plurality of air inlets are opened at the bottom of the inner cavity of the middle cavity.

[0012] As a further improvement of the technical solution, the pipe structure includes an outer pipe and an inner pipe, the outer pipe is sleeved on the outside of the inner pipe, the tops of the outer pipe and the inner pipe are fixedly connected to the bottom of the sealing ring gasket, and the bottoms of the outer pipe and the inner pipe are fixedly connected to the top of the second connecting pipe;

[0013] The outer tube is made of a hard material, and the inner tube is made of an elastic material. An inner bin is formed inside the inner tube, which can flexibly and pressure-resistantly transport high-temperature and high-pressure gaseous refrigerant. An outer bin is formed between the outer tube and the inner tube. A support component for supporting the inner tube for expansion is installed on the side of the outer bin close to the outer tube, and the bottom opening of the air inlet is connected to the outer bin.

[0014] As a further improvement of the present technical solution, the support assembly is composed of a plurality of inclined plug plates, and the plurality of inclined plug plates are all plugged and fixed in the middle of the outer tube. The inclined plug plates located on the outer wall surface of the outer tube are external fins, which are used to assist in heat dissipation of the outer tube. The inclined plug plates located inside the outer bin are internal support guides. When there is no leakage in the inner tube, the internal support guides can support the expansion of the inner tube. When there is leakage in the inner tube, high-temperature and high-pressure gaseous refrigerant is transmitted from the outer bin, and the internal support guides can guide the gaseous refrigerant.

[0015] As a further improvement of the technical solution, a buckle is fixedly connected to one end of the first connecting tube close to the sealing ring gasket, which can limit the expansion of the inner wall of the sealing ring gasket.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] 1. In the condenser pipeline interface structure, the pipeline interface mechanism can be vertically connected to the inlet pipe in the condenser pipe and the compressor pipe in a threaded connection manner through the connecting mechanism in the pipeline interface mechanism. When transporting high-temperature and high-pressure gaseous refrigerant, the elastic potential energy of the inner pipe in the pipe connection structure can withstand the pressure brought by the high-temperature and high-pressure gaseous refrigerant, ensuring the stability of the gaseous refrigerant during transportation. At the same time, it can also effectively compensate for the thermal expansion and contraction caused by temperature changes, reduce the stress concentration caused by thermal expansion and contraction, and further enhance the reliability of the transportation pipe;

[0018] 2. In the condenser pipeline interface structure, since the transported gaseous refrigerant is in a high-temperature and high-pressure state, when the inner tube is damaged by high pressure or other factors, the outer tube quickly intervenes to provide double protection for the transportation of the gaseous refrigerant and avoid direct leakage of the gaseous refrigerant. After the refrigerant is transported to the backup transportation mechanism, the gaseous refrigerant in a high-temperature state will first accumulate in the middle cavity of the sealing ring gasket. Due to the high temperature, the sealing ring gasket will expand and deform. Therefore, the staff can quickly determine whether there is a leak inside the pipeline interface structure by observing the changes in the appearance of the sealing ring gasket. This visual leak detection method greatly improves the efficiency of troubleshooting and reduces maintenance costs. BRIEF DESCRIPTION OF THE DRAWINGS

[0033] The following will be combined with the accompanying drawings in the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0034] Example 1, see Figure 1 and Figure 2 As shown, the purpose of this embodiment is to provide a condenser pipeline interface structure, including a pipeline interface mechanism 2, the pipeline interface mechanism 2 is installed at the end of the condenser body 1, the condenser body 1 includes a mounting frame 11 and an air-cooling fan 12, the air-cooling fan 12 is installed on the surface of the mounting frame 11, the mounting frame 11 is connected to a condenser tube 13 for heat exchange of the refrigerant, the two ends of the condenser tube 13 are respectively an inlet tube 14 and an outlet tube 15, the pipeline interface mechanism 2 is used to connect the inlet tube 14 with the compressor tube 16, and can transport the high-temperature and high-pressure gas compressed by the compressor to the inside of the condenser body 1 for heat exchange;

[0035] The pipeline interface mechanism 2 includes a connecting mechanism 21, a connecting pipe structure 23 and a backup conveying mechanism 22. The connecting pipe structure 23 and the backup conveying mechanism 22 are both located inside the connecting mechanism 21. When the connecting pipe structure 23 is normal and leaks free, the connecting pipe structure 23 can flexibly and pressure-resistantly convey the high-temperature and high-pressure gas. The backup conveying mechanism 22 is used to improve the sealing performance of the pipeline interface mechanism 2. When the connecting pipe structure 23 is damaged and leaks, the high-temperature and high-pressure gas can be conveyed through the backup conveying mechanism 22. At the same time, the internal transmission gas of the backup conveying mechanism 22 causes its surface to expand and deform, which can indicate a leakage.

[0036] Since the inlet pipe 14 of the condenser body 1 needs to be connected to the compressor pipe 16 of the compressor during use of the air-conditioning equipment, in view of this, the specific structure of the connecting mechanism 21 is first disclosed. The connecting mechanism 21 includes a first connecting pipe 211 and a second connecting pipe 212. The first connecting pipe 211 and the second connecting pipe 212 are threadedly connected to the inlet pipe 14 and the compressor pipe 16 respectively, and the inner walls of the first connecting pipe 211 and the second connecting pipe 212 are both paved with elastic inner walls 213.

[0037] See also Figure 2 Combined with Figure 3 As shown, when the pipeline interface mechanism 2 is installed, it is necessary to first thread the first connecting pipe 211 and the inlet pipe 14, and then thread the compressor pipe 16 and the second connecting pipe 212. In this process, the inlet pipe 14 and the compressor pipe 16 are vertically connected. This connection method can ensure that the high-temperature refrigerant gas is smoothly transported in the pipeline, and because the high-temperature gas has the characteristic of moving upward, the transportation efficiency can be further improved. With the help of the elastic inner wall 213 on the inner wall of the first connecting pipe 211 and the second connecting pipe 212, on the one hand, through the elastic deformation ability of the elastic inner wall 213, when connected with the inlet pipe 14 and the compressor pipe 16, it is tightly fitted to the outer wall of the pipeline, increasing the contact area and thus increasing the friction, reducing the loosening or displacement of the pipeline during operation, and can also buffer the vibration generated by the operation of the equipment and adapt to the thermal expansion and contraction of the pipeline caused by temperature changes, thereby improving the connection stability; on the other hand, the elastic inner wall 213 can fill the tiny gap in the connection part, effectively reducing the leakage of gaseous refrigerant and enhancing the sealing of the connection.

[0038] The gaseous refrigerant output from the compressor is in a state of high temperature and high pressure. The thermal expansion and contraction of the high-temperature gas causes the volume of the high-temperature gaseous refrigerant to expand and the density to decrease, resulting in an upward tendency of the gaseous refrigerant during transmission. The pipeline interface mechanism 2 is installed vertically as a whole. Therefore, it is necessary to further seal the first connecting pipe 211 at the upper position through the backup conveying mechanism 22. The backup conveying mechanism 22 includes a sealing ring gasket 221 fixedly connected to the bottom of the first connecting pipe 211. The sealing ring gasket 221 can wrap the lower end surface of the first connecting pipe 211. A middle cavity 222 is opened inside the sealing ring gasket 221, and a plurality of air inlets 223 are opened at the bottom of the inner cavity of the middle cavity 222.

[0039] like Figure 3 As shown, the bottom of the end of the first connecting pipe 211 away from the inlet pipe 14 is fixedly connected to the sealing ring gasket 221. The sealing ring gasket 221 wraps the bottom end surface of the first connecting pipe 211, which can effectively improve the sealing effect and reduce the leakage at the first connecting pipe 211 when the high-temperature gaseous refrigerant is transported upward.

[0040] High-temperature and high-pressure gaseous refrigerant is easy to damage the transmission pipeline under high pressure during transportation. In order to improve the transportation effect of high-temperature and high-pressure gas, it is necessary to disclose the pipe structure 23. The pipe structure 23 includes an outer pipe 231 and an inner pipe 232. The outer pipe 231 is sleeved on the outside of the inner pipe 232. The tops of the outer pipe 231 and the inner pipe 232 are fixedly connected to the bottom of the sealing ring gasket 221. The bottoms of the outer pipe 231 and the inner pipe 232 are fixedly connected to the top of the second connecting pipe 212.

[0041] The outer tube 231 is made of a hard material, and the inner tube 232 is made of an elastic material. An inner warehouse 233 is formed inside the inner tube 232, and an outer warehouse 234 is formed between the outer tube 231 and the inner tube 232. A support assembly 235 for supporting the expansion of the inner tube 232 is installed on the side of the outer warehouse 234 close to the outer tube 231, and the bottom opening of the air inlet 223 is connected to the outer warehouse 234.

[0042] See also Figure 3 As shown, when the pipeline interface mechanism 2 operates normally, the gaseous refrigerant can enter the interior of the second connecting pipe 212 from the compressor pipe 16, and then enter the interior of the inner chamber 233. Since the inner tube 232 is made of elastic material, it can effectively play a pressure-resistant role when it withstands the pressure brought by the high-temperature and high-pressure gaseous refrigerant; when the gaseous refrigerant flows in the inner chamber 233, the inner tube 232 can perform appropriate elastic deformation according to the change of pressure, thereby buffering the pressure shock and reducing the risk of the inner tube 232 being damaged due to high pressure. At the same time, this elastic potential It can not only ensure the stability of the gaseous refrigerant during the transportation process, but also effectively compensate for the thermal expansion and contraction caused by temperature changes. In terms of thermal compensation, the elasticity of the inner tube 232 can adapt to the changes in pipe size caused by temperature changes, reducing the stress concentration caused by thermal expansion and contraction of the high-temperature gaseous refrigerant when it enters the inner bin 233, and further enhancing the transportation reliability of high-temperature and high-pressure gaseous refrigerant; in addition, this thermal compensation function also helps to maintain the stability of the delivery pressure and flow rate of the gaseous refrigerant, thereby improving the delivery effect of the gaseous refrigerant.

[0043] It should be noted that: Figure 3 The dotted arrows in the figure indicate the delivery direction of the high-temperature and high-pressure gaseous refrigerant; the inner tube 232 is preferably made of rubber material, which has excellent high-temperature resistance and can maintain elasticity within a wide temperature range. The outer tube 231 is made of metal material and can provide external support for the inner tube 232.

[0044] Because the inner tube 232 is made of elastic material, when transporting high-temperature and high-pressure gaseous refrigerant, the high-temperature and high-pressure gas can cause the inner tube 232 to expand and deform. In order to reduce the damage of the inner tube 232 due to large expansion, a support assembly 235 can be set inside the outer warehouse 234 to assist in supporting the inner tube 232. The support assembly 235 is composed of a plurality of inclined plug plates 2350, and the plurality of inclined plug plates 2350 are all plugged and fixed in the middle of the outer tube 231. The inclined plug plates 2350 located on the outer wall surface of the outer tube 231 are external fins 2351, which are used for assisting the heat dissipation of the outer tube 231. The inclined plug plates 2350 located inside the outer warehouse 234 are internal support guides 2352. When there is no leakage in the inner tube 232, the internal support guides 2352 can support the expansion of the inner tube 232.

[0045] like Figure 3 As shown, when the gaseous refrigerant is transmitted in the inner tube 232, the inner tube 232 will expand and deform. At this time, the inner support guide 2352 arranged on the inner wall of the outer tube 231 can play an auxiliary supporting role for the inner tube 232, thereby reducing excessive deformation of the inner tube 232 under the expansion force and maintaining the structural stability of the inner tube 232. At the same time, the inner support guide 2352 can also effectively reduce the contact friction between the inner tube 232 and the outer tube 231. If the inner tube 232 and the outer tube 231 are in direct contact and friction, it is easy to cause wear and damage to the pipeline, thereby reducing the service life of the pipeline. The existence of the inner support guide 2352 forms a gap and support between the two, avoiding direct contact, thereby ensuring the safe and stable operation of the pipeline system.

[0046] In summary, the working principle of this embodiment is as follows: when the pipeline interface mechanism 2 is installed, the first connecting pipe 211 needs to be threadedly connected to the inlet pipe 14 first, and then the compressor pipe 16 needs to be threadedly connected to the second connecting pipe 212. When the pipeline interface mechanism 2 is operating normally, the gaseous refrigerant can enter the interior of the second connecting pipe 212 from the compressor pipe 16, and then enter the interior of the inner chamber 233. Since the inner tube 232 is made of elastic material, it can effectively play a pressure-resistant role when it withstands the pressure brought by the high-temperature and high-pressure gaseous refrigerant; when the gaseous refrigerant flows in the inner chamber 233, the inner tube 232 can The inner tube 232 undergoes moderate elastic deformation according to the change in pressure, thereby buffering the pressure shock and reducing the risk of damage to the inner tube 232 due to high pressure. At the same time, this elastic potential energy can not only ensure the stability of the gaseous refrigerant during transportation, but also effectively compensate for the thermal expansion and contraction caused by temperature changes. When the gaseous refrigerant is transmitted in the inner tube 232, the inner tube 232 will expand and deform. At this time, the inner support guide 2352 arranged on the inner wall of the outer tube 231 can provide auxiliary support for the inner tube 232. The inner support guide 2352 can effectively reduce the contact friction between the inner tube 232 and the outer tube 231.

[0047] Embodiment 2 is different from the above-mentioned embodiment 1, wherein, in combination with Figure 4 and Figure 5 As shown, when the inner tube 232 is damaged, part of the high-temperature and high-pressure gaseous refrigerant can pass through the inner tube 232 and enter the outer chamber 234. Since the high-temperature gas has an upward tendency, the high-temperature and high-pressure gaseous refrigerant will enter the upper end of the inner cavity of the outer chamber 234, and enter the middle cavity 222 of the sealing ring gasket 221 through the air inlet 223. The sealing ring gasket 221 is made of elastic material. When the high-temperature gas enters, it is accumulated in the middle cavity 222 due to the upward trend of the high temperature, causing the sealing ring gasket 221 to expand. The staff can observe the expansion effect of the sealing ring gasket 221 to assist in determining whether there is a leak in the pipeline interface mechanism 2.

[0048] The above-mentioned sealing ring gasket 221 is preferably made of rubber material with a relatively thin inner wall. When transmitting high-temperature gas, due to the characteristics of rubber, the sealing ring gasket 221 will expand more significantly. At the same time, the cross-section of the air inlet 223 is trapezoidal, and the inner diameter of the opening close to the middle cavity 222 is smaller than the inner diameter of the opening close to the outer chamber 234. Combined with the fact that high-temperature gas has an upward tendency, the high-temperature gaseous refrigerant can be more stably located inside the middle cavity 222.

[0049] in, Figure 4 The dotted arrows in the figure indicate the delivery direction of the gaseous refrigerant.

[0050] When the inner tube 232 is damaged, the bottom of the inner tube 232 continuously transports high-temperature gaseous refrigerant, and the gaseous refrigerant enters the outer chamber 234 at the damaged part. Since the outer chamber 234 is connected to the sealing ring gasket 221, the gas that enters the outer chamber 234 is transmitted to the inside of the sealing ring gasket 221, so that the leaked gaseous refrigerant is filled in the outer chamber 234 and the sealing ring gasket 221, so that the gaseous refrigerant leaked when the inner tube 232 is damaged will not leak into the air, thereby preventing the condenser from leaking gaseous refrigerant and affecting the refrigeration effect.

[0051] As the gaseous refrigerant continuously enters the middle cavity 222 of the sealing ring gasket 221, the sealing ring gasket 221 will expand. This is because the gaseous refrigerant in the sealing ring gasket 221 increases. According to the ideal gas state equation, when the temperature is constant, the increase in the amount of gas will cause the pressure to increase, and the volume of the sealing ring gasket 221 will expand accordingly. When the sealing ring gasket 221 expands to a certain extent, its internal pressure reaches equilibrium with the pressure in the outer chamber 234 and the pressure of the airflow conveyed by the inner tube 232. Under this equilibrium state, the gaseous refrigerant no longer enters the outer chamber 234, but continues to be conveyed from the inner chamber 233, maintaining the stability of the system operation and ensuring functional continuity.

[0052] At this time, the sealing ring gasket 221 will always be in an expanded state. This is because the pressure inside the sealing ring gasket 221 is higher than the external environmental pressure. In order to maintain this pressure difference, the sealing ring gasket 221 needs to maintain a certain volume, that is, to maintain an expanded state. This expanded state also plays a certain sealing role, reducing the external gas from entering the outer chamber 234, and at the same time also reminds the outside world that the inner tube 232 is damaged.

[0053] When the inner tube 232 leaks, the high-temperature and high-pressure gaseous refrigerant is transmitted from the outer chamber 234, and the inner support guide 2352 can guide the gaseous refrigerant. Figure 4 It can be seen that when the inner tube 232 is damaged, the gaseous refrigerant will enter the interior of the outer chamber 234. The inner support guide 2352 located inside the outer chamber 234 can guide and transport the gaseous refrigerant, so that the gaseous refrigerant can be transported to the air inlet 223 more quickly. At this time, the interior of the outer chamber 234 is in a high temperature state, and the external fins 2351 located on the surface of the outer tube 231 can enhance the heat dissipation effect of the outer tube 231 and enhance the service life of the outer tube 231.

[0054] It should be noted that: Figure 4 In the figure, the inclined solid arrow at the inner support guide 2352 indicates the direction in which the inner support guide 2352 guides the airflow.

[0055] When the high-temperature and high-pressure gaseous refrigerant is located inside the middle cavity 222, it will cause the sealing ring gasket 221 to expand. If the inner wall of the sealing ring gasket 221 expands and causes the inner diameter space to become smaller, it will affect the transportation of the gaseous refrigerant to a certain extent. Therefore, the first connecting tube 211 is fixedly connected to one end close to the sealing ring gasket 221 with a ring buckle 3, which can limit the expansion of the inner wall of the sealing ring gasket 221.

[0056] The improvements are: See Figure 6 As shown, the bottom end of the first connecting tube 211 is fixedly connected with a ring buckle 3, and the bottom of the ring buckle 3 is flush with the bottom end of the sealing ring gasket 221. When the sealing ring gasket 221 expands, the ring buckle 3 can effectively limit the expansion of the inner wall of the sealing ring gasket 221, thereby prompting the outer wall of the sealing ring gasket 221 to expand. On the one hand, the visual effect of the expansion of the sealing ring gasket 221 is improved, and the staff can observe the expansion state of the sealing ring gasket 221 more intuitively and clearly, so as to quickly and accurately judge whether there is a leakage inside the pipeline interface mechanism 2. On the other hand, the expansion of the outer wall of the sealing ring gasket 221 will not block or interfere with the flow channel of the gaseous refrigerant, ensuring that the gaseous refrigerant can be transported continuously and stably.

[0057] In summary, the working principle of this embodiment is as follows: when the inner tube 232 is damaged, part of the high-temperature and high-pressure gaseous refrigerant can pass through the inner tube 232 and enter the outer chamber 234. Since the high-temperature gas has an upward trend, the high-temperature and high-pressure gaseous refrigerant will enter the upper end of the inner cavity of the outer chamber 234, and enter the middle cavity 222 of the sealing ring gasket 221 through the air inlet 223. The sealing ring gasket 221 is made of elastic material. When the high-temperature gas enters, it is stored in the middle cavity 222 by virtue of the upward trend of the high temperature, causing the sealing ring gasket 221 to expand. The staff can assist in determining whether there is a leak in the pipeline interface mechanism 2 by observing the expansion effect of the sealing ring gasket 221;

[0058] When the inner tube 232 is damaged, the gaseous refrigerant will enter the interior of the outer chamber 234. The inner support guide 2352 located inside the outer chamber 234 can guide and transport the gaseous refrigerant so that the gaseous refrigerant can be transported to the air inlet 223 more quickly. At this time, the interior of the outer chamber 234 is in a high temperature state, and the outer fins 2351 located on the surface of the outer tube 231 can enhance the heat dissipation effect of the outer tube 231 and enhance the service life of the outer tube 231.
