Description

Technical Field

[0001] The invention relates to the field of air-conditioning condenser equipment, and in particular to a collecting pipe structure of a condenser. Background Art

[0002] Structurally, the condenser is generally composed of parallel standing headers, several condensing tubes for connecting the two headers, and fins arranged on the surface of the condensing tubes. During the condensation process, the header on one side distributes the cooling medium, and then the cooling medium flows into the condensing tubes. The cooling medium flows inside the condenser, transferring heat from the high-temperature medium to the low-temperature medium to achieve heat exchange. The header on the other side is responsible for collecting the cooling medium after the heat exchange, ensuring that they can flow out of the condenser smoothly, thereby completing the entire refrigeration cycle.

[0003] Based on the above situation, in the prior art, a patent with publication number CN215446969U discloses a new type of condenser collecting pipe assembly structure, including collecting pipes welded on both sides of the condenser flat tubes, the collecting pipes on both sides are respectively provided with inlet joints and liquid storage cylinders, the collecting pipes include an outer wall of the collecting pipe and an inner wall of the collecting pipe, the inner walls of the collecting pipes are welded to the condenser flat tubes, riveting holes and partition holes are opened on the outer walls of the collecting pipes, and partition holes are also opened on the inner walls of the collecting pipes, and partitions are riveted between the inner walls of the collecting pipes and the outer walls of the collecting pipes at positions corresponding to the partition holes; the inlet joint is riveted to the outer wall of the collecting pipe; the inner wall of the liquid storage cylinder is riveted to the outer wall of the collecting pipe through a connecting bracket, and the above-mentioned collecting pipes have the advantages of small deformation and high structural strength.

DETAILED DESCRIPTION

[0020] The implementation mode of the present invention is described below in conjunction with relevant embodiments. The implementation mode of the present invention is not limited to the following embodiments, and the present invention relates to relevant necessary components in the technical field, which should be regarded as the known technology in the technical field and can be known and mastered by the technical personnel in the technical field.

[0021] A collecting pipe structure of a condenser, comprising a first collecting pipe 1 and a second collecting pipe 2 symmetrically arranged, and a plurality of condensing pipes 3 for connecting and communicating the first collecting pipe 1 and the second collecting pipe 2, wherein the top and bottom ends of the first collecting pipe 1 are closed, a first partition plate 11 is arranged inside the middle section of the first collecting pipe 1, the first partition plate 11 divides the internal space of the first collecting pipe 1 into a first flow equalizing chamber 12 and a flow regulating chamber 13 parallel to each other in the upper and lower parts, a dividing chamber plate 132 is arranged inside the flow regulating chamber 13, a plurality of flow regulating channels 134 are arranged on the surface of the dividing chamber plate 132, and a flow regulating component 4 movably connected to the tube wall of the first collecting pipe 1 is arranged corresponding to the flow regulating channel 134, the top and bottom ends of the second collecting pipe 2 are closed, the middle section of the second collecting pipe 2 is arranged inside A second partition 21 is provided, which divides the internal space of the second collecting pipe 2 into a diverter chamber 22 and a second equalizing chamber 23 which are parallel to each other in an upper and lower direction. A mixing component 24 for connecting the diverter chamber 22 and the second equalizing chamber 23 is provided outside the second collecting pipe 2. The first equalizing chamber 12 is connected with the diverter chamber 22 through the condenser 3, and the second equalizing chamber 23 is connected with the flow regulating chamber 13 through the condenser 3. A collecting pipe protection device 5 is provided outside the first collecting pipe 1 and the second collecting pipe 2. The collecting pipe protection device 5 includes a first protection device 51 and a second protection device 52. The first protection device 51 is correspondingly arranged outside the first collecting pipe 1, and the second protection device 52 is correspondingly arranged outside the second collecting pipe 2.

[0022] In the manifold structure of the present invention, the first flow equalizing chamber 12 in the first manifold 1 realizes the initial equalizing flow of the refrigerant through the arrangement of the first flow equalizing orifice plate 121 and the second flow equalizing orifice plate 122, so that the refrigerant is more evenly distributed after passing through the first flow equalizing orifice plate 121 and the second flow equalizing orifice plate 122. The first flow equalizing chamber 12 passes through the equalizing holes of different apertures in the first flow equalizing orifice plate 121, thereby further optimizing the flow distribution of the refrigerant. The second flow equalizing chamber 23 in the second manifold 2 also adopts the equalizing design of the third flow equalizing orifice plate 231 and the fourth flow equalizing orifice plate 232, thereby ensuring the even distribution of the refrigerant in the second heat exchange and refrigeration process and improving the heat exchange efficiency.

[0023] The third partition 221 arranged inside the diversion chamber 22 divides it into multiple diversion sub-chambers 222. Each diversion sub-chamber 222 is connected to the first equal flow chamber 12 through a number of condensing tubes 3, thereby realizing uniform diversion of the refrigerant. The mixing flow component 24 includes a mixing flow tube 241, a drainage branch pipe 242 and a connecting main pipe 243, so that the diverted refrigerant can be fully mixed in the mixing flow tube 241, and then evenly distributed to the second equal flow chamber 23 through the connecting main pipe 243, thereby ensuring the uniformity of the refrigerant in the subsequent heat exchange process. The flow regulating component 4 drives the flow regulating conical head 43 to move at the outlet end of the flow regulating channel 134 through the flow regulating electric cylinder 42, thereby realizing the control of the refrigerant flow rate, thereby improving the heat exchange efficiency of the refrigerant and enhancing the flexibility and adaptability of the system.

[0024] The collecting pipe protection device 5 includes a first protection device 51 and a second protection device 52, which are respectively arranged on the outside of the first collecting pipe 1 and the second collecting pipe 2 to provide additional protection. The first protection device 51 and the second protection device 52 adopt a splicing design to facilitate installation and disassembly. At the same time, the first protection device 51 and the second protection device 52 are spliced ​​and fixed by the fixing bar 56, the fixing block 57, the first fixing bolt 561 and the second fixing bolt 571 to ensure the firm connection of the first protection device 51 and the second protection device 52.

[0025] As one of the preferred embodiments of the present invention, Figure 1 and Figure 2 As shown, a first flow balancing orifice plate 121 and a second flow balancing orifice plate 122 are arranged inside the first flow balancing chamber 12 in parallel along the flow direction of the refrigerant, and the four side walls of the first flow balancing orifice plate 121 and the second flow balancing orifice plate 122 are respectively connected to the inner wall of the first flow balancing chamber 12, and an inlet pipe 123 connected to the tube wall of the first collecting pipe 1 and connected to the first flow balancing chamber 12 is provided on the right side of the first flow balancing orifice plate 121, and the aperture diameter of the flow balancing holes on the surface of the first flow balancing orifice plate 121 is larger than the aperture diameter of the flow balancing holes on the surface of the second flow balancing orifice plate 122.

[0026] The refrigerant enters the first flow equalizing chamber 12 through the inlet pipe 123. Since the inlet pipe 123 is tightly connected to the tube wall of the first collecting pipe 1, it is ensured that the refrigerant will not leak into the external space. After the refrigerant enters the first flow equalizing chamber 12, it will first encounter the first flow equalizing orifice plate 121. Since the flow equalizing holes on the surface of the first flow equalizing orifice plate 121 have a larger aperture, the refrigerant can pass through these holes relatively easily and be initially dispersed in the first flow equalizing chamber 12, thereby achieving the initial equalization of the refrigerant. After the initial equalization of the refrigerant through the first flow equalizing orifice plate 121, it will continue to The refrigerant continues to flow to the second flow balancing orifice plate 122. Since the diameter of the flow balancing holes on the surface of the second flow balancing orifice plate 122 is relatively small, after the refrigerant passes through these holes, it helps to further refine the flow distribution of the refrigerant, so that it forms a more uniform and stable flow state in the first flow balancing chamber 12. After the flow balancing treatment of the first flow balancing orifice plate 121 and the second flow balancing orifice plate 122, the refrigerant will flow out evenly from various parts of the first flow balancing chamber 12, and enter the diversion sub-chamber 222 of the diversion chamber 22 through the condenser tube 3 connected to the first collecting pipe 1.

[0027] As one of the preferred embodiments of the present invention, Figure 1 As shown, the diversion chamber 22 is provided with a plurality of third partitions 221 which are arranged transversely and connected to the inner wall of the diversion chamber 22. The third partitions 221 divide the diversion chamber 22 into a plurality of diversion sub-chambers 222. Each of the diversion sub-chambers 222 is connected to the first equalizing flow chamber 12 through a plurality of condensation tubes 3.

[0028] The mixing assembly 24 includes a mixing tube 241 connected to the outer wall of the second collecting tube 2, a plurality of drainage branch pipes 242 arranged at the top of the mixing tube 241 and connected to the mixing tube 241 at one end, and a plurality of connecting main pipes 243 arranged at the bottom of the mixing tube 241 and connected to the mixing tube 241 at one end. The drainage branch pipes 242 are arranged corresponding to the flow splitter chamber 222, and the flow splitter chamber 222 is connected to the mixing tube 241 through the corresponding drainage branch pipes 242, and the mixing tube 241 is connected to the second flow equalizing chamber 23 through the connecting main pipe 243.

[0029] The interior of the flow dividing chamber 22 is provided with a plurality of third partitions 221 which are arranged transversely and connected to the inner wall of the flow dividing chamber 22. These third partitions 221 divide the flow dividing chamber 22 into a plurality of independent flow dividing sub-chambers 222. Each flow dividing sub-chamber 222 is connected to the first equalizing flow chamber 12 of the first manifold 1 through a plurality of condensing tubes 3. When the refrigerant flows out of the first equalizing flow chamber 12 of the first manifold 1, it will be evenly distributed to these condensing tubes 3 and flow into the corresponding flow dividing sub-chambers 222. In this process, the refrigerant performs the first heat exchange cooling in the condensing tubes 3 between the first equalizing flow chamber 12 and the flow dividing sub-chamber 222.

[0030] The mixing flow component 24 connects the diversion chamber 22 and the second equal flow chamber 23, and is structurally composed of a mixing flow tube 241, a drainage branch pipe 242 and a connecting main pipe 243. The mixing flow tube 241 is connected to the outer wall of the second collecting pipe 2 and is the main place for refrigerant mixing. The drainage branch pipe 242 is arranged at the top of the mixing flow tube 241, and one end is connected to the mixing flow tube 241. These drainage branch pipes 242 are arranged corresponding to the diversion sub-chamber 222 in the diversion chamber 22, ensuring that the refrigerant in each diversion sub-chamber 222 can flow into the mixing flow tube 241 through the corresponding drainage branch pipe 242. The connecting main pipe 243 is arranged at the bottom of the mixing flow tube 241, and one end is connected to the mixing flow tube 241. These connecting main pipes 243 transport the refrigerant in the mixing flow tube 241 to the second equal flow chamber 23.

[0031] When the refrigerant flows from the flow divider chamber 222 into the mixing tube 241 through the drainage branch pipe 242, it will be fully mixed in the mixing tube 241. This mixing ensures that the refrigerant has a uniform temperature and pressure distribution before flowing into the second flow equalizing chamber 23. Then, the mixed refrigerant will be evenly distributed to various parts of the second flow equalizing chamber 23 through the connecting main pipe 243, providing good conditions for the subsequent heat exchange and refrigeration process.

[0032] As one of the preferred embodiments of the present invention, Figure 1 As shown, a third flow balancing orifice plate 231 and a fourth flow balancing orifice plate 232 are provided inside the second flow balancing chamber 23, which are arranged parallel to the flow direction of the refrigerant. The side walls of the third flow balancing orifice plate 231 and the fourth flow balancing orifice plate 232 are respectively connected to the inner wall of the second flow balancing chamber 23, and the aperture of the flow balancing holes on the surface of the third flow balancing orifice plate 231 is larger than the aperture of the flow balancing holes on the surface of the fourth flow balancing orifice plate 232.

[0033] When the refrigerant enters the second flow equalizing chamber 23, it will first encounter the third flow equalizing orifice plate 231. Since the flow equalizing holes on the surface of the third flow equalizing orifice plate 231 have a larger aperture, the refrigerant can pass through these holes relatively easily and be initially dispersed in the second flow equalizing chamber 23. After the initial flow equalization through the third flow equalizing orifice plate 231, the refrigerant will continue to flow to the fourth flow equalizing orifice plate 232. Since the flow equalizing holes on the surface of the fourth flow equalizing orifice plate 232 have a smaller aperture, it helps to further refine the flow distribution of the refrigerant, so that it forms a more uniform and stable flow state in the second flow equalizing chamber 23. After the flow equalization treatment of the third flow equalizing orifice plate 231 and the fourth flow equalizing orifice plate 232, the refrigerant will flow out evenly from various parts of the second flow equalizing chamber 23, and then the refrigerant will flow into the flow regulating sub-cavity 133 corresponding to the flow regulating chamber 13 of the first collecting pipe 1 through a number of condensing tubes 3.

[0034] As one of the preferred embodiments of the present invention, Figure 1 and Figure 3As shown, the flow regulating chamber 13 divides the internal space on the right side into a plurality of flow regulating sub-chambers 133 through a chamber dividing plate 132. The flow regulating sub-chambers 133 are arranged corresponding to the flow regulating channels 134 on the chamber dividing plate 132. An outlet pipe 131 connected to the flow regulating chamber 13 is arranged through the tube wall of the first collecting pipe 1. The flow regulating sub-chamber 133 is correspondingly provided with a plurality of condensing tubes 3 connected to the second flow equalizing chamber 23.

[0035] The flow regulating assembly 4 includes a mounting sleeve 41, a current regulating electric cylinder 42 arranged inside the mounting sleeve 41, and a flow regulating conical head 43 arranged at the outlet end of the flow regulating channel 134 and connected to the telescopic rod of the current regulating electric cylinder 42. The mounting sleeve 41 passes through and is clamped between the first protective body 511. The telescopic rod of the current regulating electric cylinder 42 can be freely telescopic and pass through the tube wall of the first collecting tube 1. A sealing ring 45 is installed between the telescopic rod of the current regulating electric cylinder 42 and the tube wall of the first collecting tube 1. A plurality of buffer channels 44 are arranged inside the flow regulating conical head 43.

[0036] The mounting sleeve 41 is used to fix the current regulating electric cylinder 42 and enable it to be stably installed on the tube wall of the first collecting tube 1. The current regulating electric cylinder 42 is a driving component. Through the telescopic movement of its telescopic rod, it drives the current regulating conical head 43 to move at the outlet end of the flow regulating channel 134. The sealing ring 45 is used to ensure the sealing between the telescopic rod of the current regulating electric cylinder 42 and the tube wall of the first collecting tube 1 to prevent refrigerant leakage. The buffer channel 44 is arranged inside the flow regulating conical head 43 to provide a certain buffer space for the refrigerant during the flow regulation process.

[0037] After the flow equalization treatment in the second flow equalization chamber 23, the refrigerant flows into the flow regulating sub-chamber 133 of the flow regulating chamber 13 through a number of condensing tubes 3. These flow regulating sub-chambers 133 correspond one-to-one to the flow regulating channels 134 on the dividing chamber plate 132, ensuring that the refrigerant can be evenly distributed to each flow regulating channel 134. When the refrigerant flows into the flow regulating channel 134, the flow regulating component 4 starts to work, and the telescopic rod of the flow regulating electric cylinder 42 starts to telescope, driving the flow regulating conical head 43 to move at the outlet end of the flow regulating channel 134. Due to the shape design of the flow regulating conical head 43, when it moves to the outlet end of the flow regulating channel 134, it will block the outlet to varying degrees, thereby slowing down the flow rate of the refrigerant.

[0038] Specifically, when the flow regulating cone head 43 completely blocks the outlet end of the flow regulating channel 134, the flow rate of the refrigerant reaches the lowest; and when the flow regulating cone head 43 completely leaves the outlet end of the flow regulating channel 134, the flow rate of the refrigerant reaches the highest. By adjusting the position of the flow regulating cone head 43 at the outlet end of the flow regulating channel 134, the flow rate of the refrigerant can be accurately controlled, thereby further optimizing the heat exchange efficiency of the refrigerant. During the flow regulating process, the setting of the buffer channel 44 of the flow regulating cone head 43 can provide a certain buffer space for the refrigerant, so that it can smoothly adapt to such changes.

[0039] As one of the preferred embodiments of the present invention, Figure 1 and Figure 4 As shown, the first protective device 51 is composed of a first protective body 511 which is arranged on the front and rear sides of the first collecting pipe 1 and has a symmetrical structure. The first protective body 511 includes a protective shell 53 and a buffer layer 59 arranged between the protective shell 53 and the first collecting pipe 1. The second protective device 52 is composed of a second protective body 521 which is arranged on the front and rear sides of the second collecting pipe 2 and has a symmetrical structure. The second protective body 521 includes a protective shell 53 and a buffer layer 59 arranged between the protective shell 53 and the second collecting pipe 2. The second protective device 52 is provided with a rubber fixing plate 54 between the right side of the second collecting pipe 2 and the buffer layer 59. The surface of the rubber fixing plate 54 is provided with a fixing groove 55 which has the same external contour shape as the overall mixing component 24.

[0040] The first protective device 51 is composed of first protective bodies 511 which are arranged on the front and rear sides of the first collecting pipe 1 and have a symmetrical structure. Each first protective body 511 includes a protective shell 53 and a buffer layer 59 arranged between the protective shell 53 and the first collecting pipe 1. The protective shell 53 is the main structural part of the first protective device 51. The protective shell 53 can be made of sturdy and durable materials, which can effectively resist external physical impact and damage and protect the first collecting pipe 1 from the influence of the external environment. The buffer layer 59 is arranged between the protective shell 53 and the first collecting pipe 1. The buffer layer 59 can be made of a material with good elasticity and shock absorption performance. When the first collecting pipe 1 is subjected to external impact, the buffer layer 59 can absorb and disperse the impact force and reduce direct damage to the first collecting pipe 1. The two first protective bodies 511 are combined together by splicing to form a complete protective structure. After the splicing is completed, the corresponding fixing strips 56 and the first fixing bolts 561 are used to fix them to ensure the stability and reliability of the first protective device 51.

[0041] Correspondingly, the second protective device 52 is composed of second protective bodies 521 which are arranged on the front and rear sides of the second collecting pipe 2 and have a symmetrical structure. Each second protective body 521 also includes a protective shell 53 and a buffer layer 59 arranged between the protective shell 53 and the second collecting pipe 2. The second protective device 52 is also provided with a rubber fixing plate 54 between the right side of the second collecting pipe 2 and the buffer layer 59. The surface of the rubber fixing plate 54 is provided with a fixing groove 55 with the same external contour shape as the overall mixing component 24. Similar to the first protective device 51, the protective shell 53 and the buffer layer 59 of the second protective device 52 also provide physical protection and buffering effects respectively to protect the second collecting pipe 2 from external impact and damage.

[0042] The rubber fixing plate 54 and the fixing groove 55 on its surface are designed to fix the mixed flow component 24 to ensure the stability and reliability of the mixed flow component 24. At the same time, the rubber fixing plate 54 also has certain elasticity and shock absorption performance, which can further reduce the impact of external impact on the second collecting pipe 2 and the mixed flow component 24. The two second protective bodies 521 are also combined together by splicing to form a complete protective structure. After the splicing is completed, the corresponding fixing strips 56 and the second fixing bolts 571 are used for fixing to ensure the stability and reliability of the second protective device 52.

[0043] During the operation of the condenser, the first protective device 51 and the second protective device 52 work together to provide comprehensive protection for the first collecting pipe 1 and the second collecting pipe 2. Through their respective protective shells 53 and buffer layers 59, they can effectively resist external physical impacts and damages. At the same time, through the rubber fixing plate 54 and the fixing groove 55, the stability and reliability of the mixed flow component 24 can be ensured.

[0044] As one of the preferred embodiments of the present invention, Figure 1 and Figure 4 As shown, the first protective body 511 and the second protective body 521 are respectively connected with fixing strips 56 on the surface away from the condenser 3, and a plurality of first fixing bolts 561 with threaded connections are correspondingly arranged between the fixing strips 56 on the same side of the first protective body 511 and between the fixing strips 56 on the same side of the second protective body 521. The first protective body 511 and the second protective body 521 are respectively connected with fixing blocks 57 on the upper and lower ends of the surface of the side connected to the condenser 3, and a plurality of second fixing bolts 571 with threaded connections are arranged between the fixing blocks 57 on the same side of the first protective body 511 and between the fixing blocks 57 on the same side of the second protective body 521. The first protective body 511 and the second protective body 521 are respectively provided with protective tubes 50 at the connection points with the condenser 3.

[0045] In the collecting pipe structure of the condenser, the first protective body 511 and the second protective body 521 are external protective devices of the first collecting pipe 1 and the second collecting pipe 2 respectively. The first protective body 511 and the second protective body 521 respectively adopt symmetrical structures. On the side away from the condenser 3, the surfaces of the first protective body 511 and the second protective body 521 are respectively connected with fixing strips 56, and threaded holes are provided on the fixing strips 56 for penetrating the first fixing bolts 561.

[0046] At the upper and lower ends of the surface of one side connected to the condenser 3, the first protective body 511 and the second protective body 521 are respectively connected with fixing blocks 57, and threaded holes are also provided on these fixing blocks 57 for passing through second fixing bolts 571. By tightening the second fixing bolts 571, the connection strength between the two first protective bodies 511 and the two second protective bodies 521 can be further enhanced to ensure that they will not loosen due to vibration or external force during the operation of the condenser.

[0047] When the two first protection bodies 511 and the two second protection bodies 521 are assembled in place, the two first protection bodies 511 and the two second protection bodies 521 are firmly connected together by tightening the first fixing bolts 561, so that the first protection device 51 is formed outside the first header 1, and the second protection device 52 is formed outside the second header 2. The fixed assembly principle not only ensures the stability and reliability of the protection device, but also improves the convenience of installation. The staff only needs to assemble the two protection bodies together according to the prescribed steps and tighten the corresponding fixing bolts. The protective tube 50 is a structure arranged on the first protective body 511 and the second protective body 521 corresponding to the connection point connected to the condenser 3. The setting of the protective tube 50 can effectively protect the connection point between the condenser 3 and the first collecting tube 1 and the second collecting tube 2 to prevent loosening or damage caused by external force or vibration.

[0048] The above is only a preferred embodiment of the present invention. It should be pointed out that ordinary technicians in this technical field can make several improvements and modifications without departing from the principle of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
