Description

Technical Field

[0001] This utility model belongs to the field of refrigerant inlet and outlet manifold technology, and particularly relates to a refrigerant inlet and outlet manifold that is easy to install. Background Technology

[0002] Evaporative condensers are widely used in industries such as refrigeration and chemical processing, serving as a primary heat exchanger. Their water- and energy-saving features have secured them a broad market base. The heat exchange coil assembly is the core component of the evaporative condenser. Its function is to condense and liquefy the high-temperature, high-pressure refrigerant gas within the coil assembly, while simultaneously transferring the internal energy of the refrigerant gas to the water film on the outer surface of the heat exchange coils. This causes the water film's temperature to rise and evaporate. The evaporation of water absorbs heat, further lowering its temperature and ensuring effective condensation of the refrigerant within the heat exchange coils.

[0003] In the heat exchanger coil assembly, the refrigerant inlet and outlet manifolds serve to connect all heat exchanger tubes and refrigerant inlet and outlet pipes. Their structure must be designed to withstand pressure and not deform, facilitate welding of all heat exchanger tubes to the inlet and outlet manifolds, and ensure that the refrigerant entering from the refrigerant inlet and outlet pipes is evenly distributed in the evaporator cold manifold and evenly delivered to each heat exchanger tube.

[0004] According to authorization announcement number CN215447567U, a refrigerant inlet and outlet manifold for an evaporative condenser includes an inlet manifold and an outlet manifold fixed to the core connecting frame. The inlet manifold is on top, and the outlet manifold is on the bottom. The inlet and outlet manifolds have identical structures. Each inlet or outlet manifold includes a refrigerant pipe. One end of the refrigerant pipe has a mating flange, and the other end connects to the manifold. The manifold includes an outer side plate, an inner side plate, two upper and lower cover plates, and end-cap flanges at both ends. The other end of the refrigerant pipe is inserted into the outer side plate. The opposite side of the outer side plate has an inner side plate. Cover plates are located at the upper and lower ends between the outer and inner side plates. End-cap flanges are located at the two outer ends of the outer and inner side plates. The inner side plate has multiple heat exchange coil holes. Both the outer and inner side plates are arc-shaped plates with opposite arc openings, forming a bracket shape. The heat exchange coils are easy to weld to the refrigerant inlet and outlet manifolds and are pressure-resistant.

[0005] However, existing technologies have some problems: traditional refrigerant inlet and outlet manifolds are usually installed using welding or flange connections, which makes the process of inspecting and maintaining vapor condensers cumbersome, requires certain operational skills, and takes a long time, resulting in low efficiency. Therefore, we propose a refrigerant inlet and outlet manifold that is easy to install. Utility Model Content

[0006] To address the problems existing in the prior art, the purpose of this utility model is to provide a refrigerant inlet and outlet manifold that is easy to install. By setting a retaining ring, during installation, after the insert pipe is inserted into the connecting pipe, the retaining ring is put on the first convex ring and the second convex ring, and the nut is tightened to complete the installation.

[0007] This utility model is implemented as follows: a refrigerant inlet and outlet manifold that is easy to install includes a main pipe: an inlet pipe is provided on the main pipe, a branch pipe is provided on the main pipe, end caps are provided on both sides of the main pipe, there are multiple branch pipes, a first clamp is provided on the branch pipe, a connecting pipe is provided on the branch pipe, the connecting pipe is axially adjusted by the first clamp, a plug pipe is inserted into the connecting pipe, and a retaining ring is provided between the connecting pipe and the plug pipe for fixing the connecting pipe and the plug pipe.

[0008] Optionally, the branch pipe is provided with a travel groove, a sliding tube is slidably connected in the travel groove, a sealing plate is fixedly connected to the sliding tube, the sealing plate is correspondingly arranged with the inner wall of the branch pipe, and the sealing plate is slidably connected to the inside of the branch pipe.

[0009] Optionally, the branch pipe is provided with an annular groove, the first clamp is slidably connected to the annular groove, the annular groove is provided with a second clamp, and the first clamp and the second clamp are fastened together.

[0010] Optionally, the first clamp is provided with a threaded tube, and the sliding tube is provided with an installation groove. The threaded tube is provided in correspondence with the installation groove, and the threaded tube fits into the installation groove.

[0011] Optionally, both the sliding tube and the threaded tube are provided with threads on their outer sides, and the connecting tube is connected to the sliding tube and the threaded tube by threads.

[0012] Optionally, the connecting pipe is provided with a first protruding ring, and the insertion pipe is provided with a second protruding ring. The first protruding ring and the second protruding ring are provided correspondingly. Both the first protruding ring and the second protruding ring are provided with a sealing groove, and a sealing ring is provided in the sealing groove.

[0013] Optionally, the connecting pipe is provided with a connector, and the connector is provided corresponding to the connecting pipe.

[0014] Optionally, the retaining ring has a cavity inside, the cavity is correspondingly arranged with the first convex ring and the second convex ring, a threaded rod is hinged on the retaining ring, a nut is provided on the threaded rod, and a limit hole is formed on the retaining ring.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] 1. By setting a retaining ring, during installation, insert the plug on the connector tube into the connecting tube. The first protruding ring on the connecting tube and the second protruding ring on the connector tube will automatically align. Put the retaining ring on the first and second protruding rings, rotate the threaded rod into the limiting hole, and then tighten the nut. The nut will press the retaining ring, thus fixing the connecting tube and the connector tube.

[0017] 2. By setting up a sliding tube, when there is a deviation in the spacing of the heat exchanger tube joints, the position of the connecting tube can be moved axially for fine adjustment to adapt to heat exchanger tubes with different spacings. This flexible adaptation ensures accurate installation and efficient operation of the heat exchange system, improving the system's compatibility and flexibility.

[0018] 3. By placing a sealing ring between the two convex rings, the sealing performance between the connecting pipe and the insertion pipe can be significantly improved. After the first and second convex rings automatically align, the sealing ring is tightly compressed between the two convex rings, forming an effective sealing barrier to effectively prevent media leakage and ensure the stability and safety of the heat exchange system. In addition, the sealing ring also has a certain degree of elasticity and wear resistance, which can compensate for minor displacements caused by temperature changes, vibrations, and other factors, maintaining the durability and reliability of the connection and extending the service life of the heat exchange system.

[0026] To further understand the utility model content, features and effects of this utility model, the following embodiments are provided, and detailed descriptions are given in conjunction with the accompanying drawings.

[0027] like Figures 1 to 5 As shown in the figure, the present invention provides a refrigerant inlet and outlet manifold that is easy to install, including a main pipe 1, an inlet pipe 11 on the main pipe 1, a branch pipe 12 on the main pipe 1, end caps 13 on both sides of the main pipe 1, multiple branch pipes 12, a first clamp 23 on the branch pipe 12, a connecting pipe 2 on the branch pipe 12, the connecting pipe 2 being axially adjusted by the first clamp 23, an insertion pipe 3 being inserted into the connecting pipe 2, and a retaining ring 4 being provided between the connecting pipe 2 and the insertion pipe 3 for fixing the connecting pipe 2 and the insertion pipe 3.

[0028] Furthermore, the first clamp 23 enables axial adjustment of the connecting pipe 2, facilitating refrigerant pipeline connection requirements at different locations and improving installation flexibility and convenience. Simultaneously, the design of the retaining ring 4 simplifies the fixing process of the connecting pipe 2 and the insertion pipe 3, eliminating the need for complex welding or threaded connections and significantly shortening installation time. In addition, the multiple branch pipes 12 ensure even distribution of refrigerant to each branch pipe, improving the efficiency and stability of the refrigeration system and ensuring the overall system performance.

[0029] Specifically, the branch pipe 12 is provided with a travel groove 15, and a sliding tube 21 is slidably connected in the travel groove 15. A sealing plate 28 is fixedly connected to the sliding tube 21. The sealing plate 28 is correspondingly arranged with the inner wall of the branch pipe 12, and the sealing plate 28 is slidably connected to the inside of the branch pipe 12.

[0030] Furthermore, the design of creating a travel groove 15 on the branch pipe 12 and slidingly connecting it to the sliding tube 21 provides greater flexibility and adaptability for the refrigerant entering and exiting the manifold. The sealing plate 28 on the sliding tube 21 closely corresponds to the inner wall of the branch pipe 12, which not only ensures the sealing of the refrigerant in the pipeline and prevents leakage, but also enables fine adjustment of the refrigerant flow rate through the sliding connection of the sealing plate 28 inside the branch pipe 12.

[0031] Specifically, the branch pipe 12 is provided with an annular groove 14, the first clamp 23 is slidably connected to the annular groove 14, the annular groove 14 is provided with a second clamp 25, and the first clamp 23 and the second clamp 25 are fastened together.

[0032] Furthermore, a first clamp 23 is slidably connected to the annular groove 14, and a second clamp 25 is fastened to the first clamp 23 within the annular groove 14, greatly improving the installation flexibility and adjustment convenience of the refrigerant inlet and outlet manifolds. By sliding the position of the first clamp 23 within the annular groove 14, the relative position between the connecting pipe 2 and the branch pipe 12 can be easily adjusted to meet diverse installation needs. The addition of the second clamp 25 ensures the stability of the first clamp 23, preventing it from loosening during use.

[0033] Specifically, the first clamp 23 is provided with a threaded tube 24, and the sliding tube 21 is provided with an installation groove 22. The threaded tube 24 is provided in correspondence with the installation groove 22, and the threaded tube 24 fits into the installation groove 22.

[0034] Furthermore, the tight fit between the threaded pipe 24 and the mounting groove 22 not only enhances the connection strength between the first clamp 23 and the sliding pipe 21, preventing loosening caused by vibration or pressure changes, but also ensures the accuracy and stability of the axial adjustment of the connecting pipe 2. This makes the system more precise in refrigerant flow regulation and distribution, improves the overall refrigeration efficiency, and simplifies the installation and maintenance process, reducing the difficulty and cost of operation.

[0035] Specifically, both the sliding tube 21 and the threaded tube 24 are provided with threads on their outer sides, and the connecting tube 2 is connected to the sliding tube 21 and the threaded tube 24 by threads.

[0036] Furthermore, both the sliding tube 21 and the threaded tube 24 are threaded on the outside, and are connected to the connecting tube 2 via threads. This design greatly facilitates the assembly and disassembly of the refrigerant inlet and outlet manifolds. This connection method eliminates the need for complex welding or glue fixation, significantly simplifying the installation process and improving work efficiency. At the same time, the tightness and stability of the threaded connection ensures leak-free refrigerant transmission within the pipeline, guaranteeing the safety and stability of the system. In addition, this design facilitates later maintenance and repair work; components can be easily disassembled and replaced simply by turning the threads, reducing maintenance costs and difficulty.

[0037] Specifically, the connecting pipe 2 is provided with a first protruding ring 26, and the insertion pipe 3 is provided with a second protruding ring 31. The first protruding ring 26 and the second protruding ring 31 are provided correspondingly. Both the first protruding ring 26 and the second protruding ring 31 are provided with sealing grooves 27. A sealing ring 33 is provided in the sealing grooves 27. The insertion pipe 3 is provided with a plug connector 32, which is provided correspondingly to the connecting pipe 2.

[0038] Furthermore, the first protruding ring 26 and the second protruding ring 31 respectively provided on the connecting pipe 2 and the plug pipe 3, along with the sealing groove 27 and the built-in sealing ring 33, together constitute an efficient and reliable sealing system. This design ensures a tight connection between the plug 32 and the connecting pipe 2, effectively preventing refrigerant leakage and guaranteeing the efficient operation of the piping system. At the same time, the presence of the sealing ring 33 enhances the system's pressure resistance and durability, enabling it to withstand high operating pressures and long-term operational wear. In addition, this structure facilitates installation and disassembly, reduces maintenance costs, and improves the overall system stability and safety.

[0039] Specifically, the retaining ring 4 has a cavity 41 inside, which is correspondingly arranged with the first convex ring 26 and the second convex ring 31.

[0040] Furthermore, the retaining ring 4 has an internal cavity 41 corresponding to the first convex ring 26 and the second convex ring 31. This not only enhances the fit between the retaining ring 4 and the convex rings but also achieves a quick and stable connection through the hinged threaded rod 42 and nut 43. The limiting hole 44 ensures the accuracy of the threaded rod 42 during tightening. This design simplifies the installation process, improves work efficiency, and ensures the stability and sealing of the refrigerant inlet and outlet manifold connection.

[0041] Working principle: During installation, insert the connector 32 on the insertion tube 3 into the connecting tube 2. The first protruding ring 26 on the connecting tube 2 and the second protruding ring 31 on the insertion tube 3 automatically align. Place the retaining ring 4 on the first protruding ring 26 and the second protruding ring 31, rotate the threaded rod 42 into the limiting hole 44, and then tighten the nut 43. The nut 43 presses the retaining ring 4, thus fixing the connecting tube 2 and the insertion tube 3. A sealing ring 33 is set between the two protruding rings, which can improve the sealing performance between the connecting tube 2 and the insertion tube 3. After the first protruding ring 26 and the second protruding ring 31 automatically align, the sealing ring 33 is tightly compressed between the two protruding rings, forming an effective sealing barrier, effectively preventing media leakage and ensuring the stability and safety of the heat exchange system.
