Description

Technical Field

[0001] This utility model relates to the field of cooling device technology, and in particular to a dry cooling coil connection structure. Background Technology

[0002] Currently, existing coolers typically use fixing plates attached to the outside of the manifolds and welding them to secure the manifolds to the dry cooling coils. Furthermore, the connecting pipes of the manifold assembly are directly fixed to the frame using welded protective plates, without allowing for any misalignment between manifolds or between the manifolds and the frame. This makes it impossible to adjust the relative positions of the components after welding, and also prevents effective stress relief from external forces and vibrations experienced by the cooler during use. Consequently, the dry cooling coil connection structure suffers from complex manufacturing and assembly processes, is prone to damage to the outer coating of the manifolds and frame structure during use, and is susceptible to weld debonding.

[0026] In this embodiment, as shown in the appendix Figure 1 As shown, a dry cooling coil connection structure is disclosed, including an inlet manifold assembly 2 connected to the inlet end 12 of the cooling coil 1, an outlet manifold assembly 3 connected to the outlet end 11 of the cooling coil 1, and a support assembly 4 for constraining the outlet manifold assembly 3 and the inlet manifold assembly 2. The inlet manifold assembly 2 includes an inlet riser 21 and multiple inlet pipes 22 connected to the inlet riser 21, each inlet pipe 22 being connected to the corresponding inlet end 12 of the cooling coil 1. The outlet manifold assembly 3 includes an outlet riser 31 and multiple outlet pipes 32 connected to the outlet riser 31, each outlet pipe 32 being connected to the corresponding outlet end 11 of the cooling coil 1. The interconnection of multiple pipes allows for more frequent liquid exchange in the dry cooling coil, improving liquid cooling efficiency. A first prefabricated base 211 is fixed on the side of the inlet riser 21 away from the cooling coil 1, and a second prefabricated base 311 is fixed on the side of the outlet riser 31 away from the cooling coil 1 and at a position corresponding to the first prefabricated base 211. The first and second prefabricated bases 211 are respectively provided with first through grooves 212 along a first direction. The support assembly 4 includes a pipe assembly connection assembly 41, which includes a pipe assembly fixing plate 42 and fasteners 43. The pipe assembly fixing plate 42 is provided with multiple second through grooves 422 along a second direction, and each second through groove 422 overlaps with at least one first through groove 212. The second direction is perpendicular to the first direction. Each fastener 43 connects the pipe assembly fixing plate 42 to the first prefabricated base 211 and the second prefabricated base 311 respectively through the through-connecting second through groove 422 and the corresponding first through groove 212. In this embodiment, the fasteners 43 can be connected by rivets or bolts. The cross-shaped hole formed by the perpendicular first through groove 212 and second through groove 422 allows for position adjustment during assembly, effectively eliminating assembly errors of the inlet vertical pipe 21 and the outlet vertical pipe 31. At the same time, due to the presence of the first through groove 212 and the second through groove 422, when the cooler is subjected to strong external vibration during use, the relative position or distance of the inlet manifold assembly 2 and the outlet manifold assembly 3 can be finely adjusted by the sliding of the fasteners 43 in the first through groove 212 or the second through groove 422 after being pressed. This allows the cooler to effectively release stresses such as external vibrations during use, thereby strengthening the connection structure and providing shock and torsion protection.

[0027] like Figure 2As shown, in some specific embodiments, the inlet riser 21 has multiple first prefabricated bases 211 distributed along the length of the pipe body, and the outlet riser 31 has multiple second prefabricated bases 311 corresponding to the first prefabricated bases 211 along the length of the pipe body. The support assembly 4 includes multiple pipe group fixing plates 42, each pipe group fixing plate 42 is connected to a first prefabricated base 211 and a second prefabricated base 311. The two risers exchange liquid with the cooling coil 1 through multiple inserts. During installation and use, the risers are subjected to liquid impact in multiple places. It is necessary to use the connection between multiple prefabricated bases and pipe group fixing plates to position multiple points of the outlet riser 31 and the inlet riser 21 to achieve overall stability.

[0028] like Figure 3 As shown, in some specific embodiments, a plurality of parallel first through slots 212 are provided on the first prefabricated base 211 along the length of the water inlet vertical pipe 21, and a plurality of parallel first through slots 212 are provided on the second prefabricated base 311 along the length of the water outlet vertical pipe 31. Two sets of through slots 421 are provided on the pipe assembly fixing plate 42 corresponding to the areas of the first prefabricated base 211 and the second prefabricated base 311. The through slots 421 include multiple second through slots 422 arranged in parallel along the length direction perpendicular to the water inlet vertical pipe 21. The second through slots 422 in the two sets of through slots 421 are not interconnected. The second through slots 422 on the multiple sets of through slots 421 form multiple cross-shaped holes with the first through slots 211 to eliminate assembly errors of the water inlet vertical pipe 21 and the water outlet vertical pipe 31. Each cross-shaped hole can be independently fine-tuned during the assembly process, which is convenient for installation. Under the condition that the water inlet vertical pipe 21 and the water outlet vertical pipe 31 are kept connected, the presence of multiple first through slots 212 and multiple second through slots 422 makes the range of fine-tuning of the relative position of the water inlet manifold assembly 2 and the water outlet manifold assembly 3 larger when the cooler is subjected to strong external vibration during use. This allows the cooler to release stress such as external vibration during use more effectively and increases the stability of the overall structure.

[0029] like Figure 4 As shown, in some specific embodiments, the upper and lower edges of the pipe assembly fixing plate 42 are respectively constructed with a first side strip 423 and a second side strip 424 bent towards the cooling coil 1. The distance between the first side strip 423 and the second side strip 424 is greater than the length of the first prefabricated base 211 and the length of the second prefabricated base 311. The first side strip 423 and the second side strip 424 can restrict the first prefabricated base 211 and the second prefabricated base 311 within the pipe assembly fixing plate 42. The initial positioning of the side strip and the prefabricated base can facilitate the initial positioning of the first through groove 212 and the second through groove 422, which is convenient for installation.

[0030] like Figure 5As shown, in some specific embodiments, the water outlet manifold assembly 3 also includes an outlet connection pipe 33, one end of which is connected to the water outlet riser pipe 31, and the other end of which is equipped with an outlet connection flange 34. The inlet manifold assembly 2 also includes an inlet connecting pipe 23. One end of the inlet connecting pipe 23 is connected to the inlet riser 21, and the other end of the inlet is equipped with an inlet connecting flange 24. Liquid exchange is carried out through the flange. In this embodiment, the height of the inlet riser 21 is higher than that of the outlet riser 31, and the inlet connecting pipe 23 is located above the outlet riser 31. The inlet riser 21 and the outlet riser 31 are arranged in an alternating manner so that the connecting pipes are not intertwined, making the arrangement clearer and easier for users to identify the manifold assembly and operate. Since the inlet riser 21 and the outlet riser 31 are arranged in an alternating manner, the inlet inserts 22 and the outlet inserts 32 located at both ends of the inlet riser 21 and the outlet riser 31 are set as U-shaped inserts. Through the U-shaped pipes, the staggered inlet riser 21 and the outlet riser 31 can connect the inserts parallel to the cooling coil 1.

[0031] In some specific embodiments, the support assembly 4 further includes an outlet connection assembly 44 and an inlet connection assembly 45. The outlet connection assembly 44 includes an outlet sleeve plate 441 and an outlet connection plate 442. The outlet sleeve plate 441 has a first connecting channel 443. The outlet connection pipe 33 passes through the first connecting channel 443 and is fixedly connected to the outlet sleeve plate 441. The two ends of the outlet connection plate 442 are respectively connected to the outlet sleeve plate 441 and the cooling coil frame 5 by fasteners 43. Through the cooperation of the outlet sleeve plate 441 and the outlet connection plate 442, the outlet connection pipe 33 and the cooling coil frame 5 are limited and supported at the same time. A part of the stress of the outlet connection pipe 33 is distributed to the cooling coil frame 5, reducing the pressure on the outlet vertical pipe 31 and increasing the service life of the outlet manifold assembly 3.

[0032] The water inlet connection assembly 45 includes a water inlet sleeve plate 451 and a water inlet connecting plate 452. The water inlet sleeve plate 451 has a second connecting channel 453. The inlet connecting pipe 23 passes through the second connecting channel 453 and is fixedly connected to the water inlet sleeve plate 451. The two ends of the water inlet connecting plate 452 are connected to the water inlet sleeve plate 451 and the cooling coil frame 5 respectively by fasteners 43. Through the cooperation of the water inlet sleeve plate 451 and the water inlet connecting plate 452, the inlet connecting pipe 23 and the cooling coil frame 5 are limited and supported at the same time. A part of the stress supporting the inlet connecting pipe 23 is distributed to the cooling coil frame 5, reducing the pressure on the water inlet vertical pipe 21 and increasing the service life of the water inlet manifold assembly 2.

[0033] like Figure 6As shown, in some specific embodiments, the water outlet connecting plate 442 has an inwardly recessed first groove 444 formed around the outlet connecting pipe 33 at one end near the outlet connecting pipe 33. The bottom of the first groove 444 matches the corresponding side wall curved surface of the outlet connecting pipe 33. The overlapping area of ​​the water outlet connecting plate 442 and the water outlet sleeve plate 441 is connected by fasteners 43. The cooperation between the first groove 444 and the side wall curved surface makes the water outlet connecting plate 442 fit the outlet connecting pipe 33 more closely, which facilitates the installation and contact of the outlet connecting pipe 33.

[0034] The water inlet connecting plate 452 has an inwardly recessed second groove 454 at one end near the inlet connecting pipe 23 for surrounding the inlet connecting pipe 23. The bottom of the second groove 454 matches the corresponding side wall curved surface of the inlet connecting pipe 23. The overlapping area of ​​the water inlet connecting plate 452 and the water inlet sleeve plate 451 is connected by fasteners 43. The cooperation between the second groove 454 and the side wall curved surface makes the water inlet connecting plate 452 fit the inlet connecting pipe 23 more closely, which facilitates the installation and abutment of the inlet connecting pipe 23.

[0035] like Figure 7 As shown, in some specific embodiments, the first groove 444 includes a first guide groove 445 for the outlet connecting pipe 33 to be inserted and a first abutting part 446 for abutting the outlet connecting pipe 33. The inlet of the first guide groove 445 is located at the end of the water outlet connecting plate 442, and the outlet is connected to the first abutting part 446. The first abutting part 446 is constructed as a semi-circle that matches the curved surface of the pipe wall of the outlet connecting pipe 33. The width of the first guide groove 445 is slightly larger than the diameter of the outlet connecting pipe 33 and the same as the maximum width of the first abutting part 446. The outlet connecting pipe 33 can enter the first abutting part 446 through the first guide groove 445. The semi-circular first abutting part can more closely limit the outlet connecting pipe 33, enhancing the practicality and stability of the water outlet connecting plate 442.

[0036] In this embodiment, the second groove 454 includes a second guide groove 455 for the inlet connecting pipe 23 to be inserted and a second abutting part 456 for abutting the inlet connecting pipe 23. The inlet of the second guide groove 455 is located at the end of the water inlet connecting plate 452, and the outlet is connected to the second abutting part 456. The second abutting part 456 is constructed as a semi-circle that matches the curved surface of the pipe wall of the inlet connecting pipe 23. The width of the second guide groove 455 is slightly larger than the diameter of the inlet connecting pipe 23 and the same as the maximum width of the second abutting part 456. The inlet connecting pipe 23 can enter the second abutting part 456 through the second guide groove 455. The semi-circular first abutting part can more closely limit the inlet connecting pipe 23, enhancing the practicality and stability of the water inlet connecting plate 452.

[0037] In some specific embodiments, the outlet connecting plate 442 is provided with a plurality of fasteners 43 connected to the outlet sleeve plate 441 on both sides of the first guide groove 445 and around the first abutment portion 446. The inlet connecting plate 452 is provided with a plurality of fasteners 43 connected to the inlet sleeve plate 451 on both sides of the second guide groove 455 and around the second abutment portion 456. The cooperation of the plurality of fasteners 43 limits the connection plate and the sleeve plate, preventing the connection plate and the sleeve plate from falling off under external pressure.

[0038] In some specific embodiments, the water outlet connection plate 442 has a plurality of third through slots 46 along a third direction at one end near the cooling coil frame 5, and the cooling coil frame 5 has a plurality of fourth through slots along a fourth direction at the corresponding position, with the third direction being perpendicular to the fourth direction. Each fastener 43 fixes the water outlet connecting plate 442 to the cooling coil frame 5 by passing through the third through groove 46 and the corresponding fourth through groove. The water outlet connecting plate 442 is arranged on the side of the cooling coil frame 5 near the cooling coil and is protected inside the cooling coil frame 5. The cross-shaped hole formed by the perpendicular third through groove 46 and the fourth through groove of the water outlet connecting plate 442 eliminates the assembly error between the water outlet connecting plate 442 and the cooling coil frame 5. When the fastener 43 is fixed, due to the presence of the third through groove 46 and the fourth through groove, when the cooler is subjected to strong external vibration during use, the relative position or distance between the water outlet manifold assembly 3 and the cooling coil 5 can be finely adjusted by the sliding of the fastener 43 in the third through groove 46 or the fourth through groove after being pressed. This allows the cooler to effectively release the stress of external vibration during use and strengthens the connection structure and provides shock and torsion protection between the outlet connecting pipe 33 and the cooling coil frame 5.

[0039] In this embodiment, the water inlet connecting plate 452 has a plurality of third through slots 46 along a third direction at one end near the cooling coil frame 5, and the cooling coil frame 5 has a plurality of fourth through slots along a fourth direction at the corresponding position, with the third direction being perpendicular to the fourth direction. Each fastener 43 fixes the water inlet connecting plate 452 to the cooling coil frame 5 by passing through the third through groove 46 and the corresponding fourth through groove. The water inlet connecting plate 452 is arranged on the side of the cooling coil frame 5 near the cooling coil and is protected inside the cooling coil frame 5. The cross-shaped hole formed by the perpendicular third through groove 46 and the fourth through groove of the water inlet connecting plate 452 eliminates the assembly error between the water inlet connecting plate 452 and the cooling coil frame 5. When the fastener 43 is fixed, due to the presence of the third through groove 46 and the fourth through groove, when the cooler is subjected to strong external vibration during use, the relative position or distance between the water inlet manifold assembly 4 and the cooling coil 5 can be finely adjusted by the sliding of the fastener 43 in the third through groove 46 or the fourth through groove 51 after being pressed. This allows the cooler to effectively release the stress of external vibration during use and strengthens the connection structure and provides shock and torsion protection between the inlet connecting pipe 23 and the cooling coil frame 5.

[0040] In some specific embodiments, the cooling coil frame 5 includes a side frame beam for connecting the inlet pipe 22 and the outlet pipe 32. The side frame beam has side walls that bend toward the inlet vertical pipe 21 on both sides. Multiple sets of fourth through slots are opened on the side walls, which are respectively connected to the outlet connecting plate 442 and the inlet connecting plate 452. The bent side walls can protect the inlet connecting plate 452 and the outlet connecting plate 442. The cross-shaped waist-shaped holes formed by the multiple sets of fourth through slots 51 and the third through slots 46 perpendicular to each other eliminate the assembly errors of the inlet and outlet connecting plates and the side frame beam.

[0041] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
