Description

Technical Field

[0001] This utility model relates to the field of refrigeration equipment, and more specifically, to a heat exchange unit and a condenser including the same. Background Technology

[0002] Evaporative cooling chillers are central air conditioning units that use evaporative condensers, employing air and water as the cold source and chilled water as the cooling medium. The evaporative condenser is the core of the evaporative cooling chiller unit; it uses water and air as the cooling medium, fully utilizing renewable dry air energy, allowing airflow and water evaporation to remove the condensation heat of the refrigerant. Existing evaporative condensers generally use double-tube clamps with metal plates to fix the heat exchange tubes. These clamps cover a relatively large area of ​​the heat exchange tube surface, which obstructs the cooling water flowing onto the tubes, creating a large dead zone and affecting the condenser's heat exchange performance. Utility Model Content

[0003] The present invention aims to overcome at least one of the defects of the prior art and provides a heat exchange unit and a condenser including the same, with the purpose of reducing water flow obstruction to the heat exchange tubes.

[0004] The primary objective of this invention is to provide a heat exchange unit comprising a first heat exchange tube, a second heat exchange tube, and several fixing components.

[0005] The first heat exchange tube has continuous "S"-shaped bends, forming several first straight pipe segments and several first U-shaped pipe segments connected between each of the first straight pipe segments. The two ends of the first heat exchange tube are respectively provided with a first front opening and a first end opening. The second heat exchange tube has continuous "S"-shaped bends, forming several second straight pipe segments and several second U-shaped pipe segments connected between each of the second straight pipe segments. The two ends of the second heat exchange tube are respectively provided with a second front opening and a second end opening. The fixing assembly is arranged at intervals along the length direction of the first straight pipe segments and the second straight pipe segments. The first heat exchange tube and the second heat exchange tube are fixed to the fixing assembly in an alternating manner. The first straight pipe segments and the second straight pipe segments are parallel to each other and arranged at intervals.

[0006] The fixing component includes a first positioning member for fixing the first heat exchange tube and a second positioning member for fixing the second heat exchange tube;

[0007] The first positioning member includes a first positioning part and a first isolation part that are connected at right angles to each other and have an extension length in both the vertical and horizontal directions. The first isolation part is disposed between the first straight pipe section and the second straight pipe section. The first positioning part is provided with a plurality of first positioning holes from top to bottom. The first straight pipe section passes through the first positioning holes for fixing.

[0008] The second positioning component includes a second positioning part and a second isolation part that are connected at right angles to each other and have an extension length in both the vertical and horizontal directions. The second isolation part is disposed between the second straight pipe section and the first straight pipe section. The first isolation part and the second isolation part are fixedly connected. The second positioning part is provided with a plurality of second positioning holes from top to bottom. The second straight pipe section passes through the second positioning holes for fixing. The first positioning holes and the second positioning holes are staggered vertically.

[0009] In this design, a fixing assembly is constructed using a first positioning part, a first isolation part, a second positioning part, and a second isolation part. Only the thickness of the first and second positioning parts obstructs the downward-facing water spray, resulting in a small obstruction area. Combined with the staggered arrangement of the first and second heat exchange tubes, the uniformity and coverage of the water film are improved, significantly reducing the dead zone and enhancing heat exchange efficiency. Furthermore, the fixed connection between the first and second isolation parts enhances the overall stability of the fixing assembly. Moreover, by arranging several fixing components along the front-back direction of the straight pipe section, uniform and reliable fixing and limiting of the first and second heat exchange tubes are achieved, preventing water film breakage or unevenness caused by structural loosening.

[0010] In some embodiments, the heat exchange unit further includes several fixing components;

[0011] The first isolation portion and the second isolation portion overlap at least partially, and the overlapping portion between the first isolation portion and the second isolation portion is provided with a plurality of through holes. The fastener passes through the through holes to fix the first isolation portion and the second isolation portion.

[0012] This solution simplifies the fixing method between the first isolation section and the second isolation section, and reduces the obstruction of the first isolation section and the second isolation section on the gap between the first heat exchange tube and the second heat exchange tube. This helps to further reduce the dead zone of water spray and promote the downward conduction of cooling water to form a water film.

[0013] In some embodiments, the first isolation section is provided with a plurality of first notches whose positions correspond one-to-one with the first positioning holes. The first notches are integrally connected with the corresponding first positioning holes, and the first straight pipe section is disposed close to the second isolation section through the first notches.

[0014] This design separates the first heat exchange tube and the second heat exchange tube radially only through the second isolation section, which improves the compact radial layout of the first and second heat exchange tubes and reduces the space occupied by the heat exchange unit.

[0015] In some embodiments, the second isolation section is provided with a plurality of second notches whose positions correspond one-to-one with the second positioning holes. The second notches are integrally connected with the corresponding second positioning holes, and the second straight pipe section is disposed close to the first isolation section through the second notches.

[0016] This design separates the second heat exchange tube from the first heat exchange tube radially only through the first isolation part, which improves the compact radial layout of the first and second heat exchange tubes and reduces the space occupied by the heat exchange unit.

[0017] In some embodiments, the first positioning member further includes a first limiting portion having an extension length in the vertical direction, the first limiting portion being disposed on the radially outer side of the first straight pipe section and being connected at a right angle to the first positioning portion.

[0018] This solution can improve the positioning stability of the fixing component for the first heat exchange tube by using the first limiting part.

[0019] In some embodiments, the second positioning member further includes a second limiting portion having an extension length in the vertical direction, the second limiting portion being disposed on the radially outer side of the second straight pipe section and being connected at a right angle to the second positioning portion.

[0020] This solution can improve the positioning stability of the fixing component for the second heat exchange tube by using the second limiting part.

[0021] In some embodiments, the fixing components include a first type of fixing component and a second type of fixing component, wherein the first type of fixing component fixes the middle section of the first straight pipe segment and the middle section of the second straight pipe segment, and the second type of fixing component is disposed close to the first U-shaped pipe segment and the second U-shaped pipe segment;

[0022] The second type of fixing component includes a limiting member having an extended length in the vertical direction. The limiting member is disposed on the outside of the first U-shaped tube segment and the second U-shaped tube segment and is connected at a right angle to the first limiting part.

[0023] This solution can limit the axial movement of the first and second heat exchange tubes by using limiting components, preventing the first and second heat exchange tubes from separating along the length of the straight tube and reducing loosening, thereby improving the positioning stability of the first and second heat exchange tubes.

[0024] In some embodiments, the first front opening and the second front opening are located on the same side of the heat exchange unit and are close to each other, and the first end opening and the second end opening are located on the same side of the heat exchange unit and are close to each other.

[0025] This design facilitates the connection of the first and second front openings of the heat exchange unit to the same gas collection device, and also facilitates the connection of the first and second end openings to the same liquid collection device, significantly reducing the complexity of the pipeline layout.

[0026] In some embodiments, the first front opening, the first end opening, the second front opening, and the second end opening are all located on the same side of the heat exchange unit.

[0027] This design allows for the arrangement of the gas collection device and the liquid collection device on the same side, contributing to a compact layout of the condenser system.

[0028] In some embodiments, the first front opening, the first end opening, the second front opening, and the second end opening all extend outward from the fixing component.

[0029] The second objective of this utility model is to provide a condenser, including a frame, a gas collecting chamber, a liquid collecting chamber, and multiple heat exchange units;

[0030] The gas collecting chamber and the liquid collecting chamber are disposed on the frame;

[0031] The heat exchange units are supported and fixed within the internal space of the frame, and the heat exchange units are arranged parallel to each other and spaced apart.

[0032] The first front opening and the second front opening of each heat exchange unit are connected to the gas collecting pipe, and the first end opening and the second end opening of each heat exchange unit are connected to the liquid collecting pipe.

[0033] In some embodiments, the first front opening and the second front opening of each heat exchange unit are located above the corresponding first end opening and the corresponding second end opening, and the gas collection chamber and the liquid collection chamber are arranged vertically.

[0034] In some embodiments, the gas collecting chamber is provided with an air inlet pipe, and the liquid collecting chamber is provided with a liquid supply pipe.

[0035] Compared with the prior art, the beneficial effects of this utility model are as follows: By constructing a fixing assembly with a first positioning part, a first isolation part, a second positioning part, and a second isolation part, only the thickness of the first and second positioning parts blocks the water spray from the corresponding heat exchange tubes, significantly reducing the blocking effect of the fixing assembly on the sprayed water. Furthermore, the staggered arrangement of the first and second heat exchange tubes improves the uniformity and coverage of the water film, reduces dead zones in the water spray, and solves the problem of uneven water spray. By providing a first notch communicating with the first positioning hole in the first isolation part and a second notch communicating with the second positioning hole in the second isolation part, the radial distance between the first and second heat exchange tubes is shortened, reducing the overall size of the heat exchange unit and improving the heat exchange performance of the condenser in the same volume. Through the combined action of the first limiting part, the second limiting part, and the limiting member, the structural strength of the fixing assembly is improved, and the limiting effect on the first and second heat exchange tubes is strengthened, significantly reducing looseness between the first and second heat exchange tubes and helping the heat exchange unit form a stable and uniform water film.

[0046] Example 1

[0047] like Figure 1-5 As shown, this embodiment provides a heat exchange unit, including a first heat exchange tube 100, a second heat exchange tube 200, and several fixing components 300;

[0048] The first heat exchange tube 100 has continuous "S"-shaped bends, forming several first straight tube segments 110 and several first U-shaped tube segments 120 connected between each first straight tube segment 110; the second heat exchange tube 200 has continuous "S"-shaped bends, forming several second straight tube segments 210 and several second U-shaped tube segments 220 connected between each second straight tube segment 210; the fixing assembly 300 is arranged at intervals along the length direction of the first straight tube segment 110 and the second straight tube segment 210, and the first heat exchange tube 100 and the second heat exchange tube 200 are fixed to the fixing assembly 300 in an alternating manner, and the first straight tube segments 110 and the second straight tube segments 210 are parallel to each other and arranged at intervals.

[0049] The fixing assembly 300 includes a first positioning member for fixing the first heat exchange tube 100 and a second positioning member for fixing the second heat exchange tube 200; continue to refer to Figure 2 , 5 The first positioning component includes a first positioning part 311 and a first isolation part 312 that are connected at right angles to each other and have an extension length in both the vertical and horizontal directions. The first isolation part 312 is disposed between the first straight pipe section 110 and the second straight pipe section 210. The first positioning part 311 is provided with a plurality of first positioning holes 313 from top to bottom. The first straight pipe section 110 passes through the first positioning holes 313 for fixing.

[0050] refer to Figure 1 , 2 4. The second positioning component includes a second positioning part 321 and a second isolation part 322 that are connected at right angles to each other and have an extension length in both the vertical and horizontal directions. The second isolation part 322 is disposed between the second straight pipe section 210 and the first straight pipe section 110. The first isolation part 312 and the second isolation part 322 are fixedly connected. The second positioning part 321 is provided with a plurality of second positioning holes 323 from top to bottom. The second straight pipe section 210 passes through the second positioning holes 323 for fixing. The first positioning holes 313 and the second positioning holes 323 are arranged alternately vertically.

[0051] In order to make the structure compact, the first positioning part 311, the first isolation part 312, the second positioning part 321, and the second isolation part 322 are all made of thin metal plates. This can further reduce the obstruction area of ​​the first positioning part 311 and the second positioning part 321 on the heat exchange tube from the top view. When the cooling water is sprayed from top to bottom toward the heat exchange unit, the obstruction effect of the fixing component 300 on the cooling water is small, which helps to reduce the water spray dead zone and improve the heat exchange efficiency of the heat exchange unit.

[0052] refer to Figure 1 , 4In specific implementation, the heat exchange unit also includes several fixing members 330; the first isolation part 312 and the second isolation part 322 at least partially overlap, and the overlapping portion between the first isolation part 312 and the second isolation part 322 is provided with several through holes. The fixing members 330 pass through the through holes to fix the first isolation part 312 and the second isolation part 322. In specific implementation, in order to reduce the space occupied by the fixing members 330 in the radial direction of the heat exchange tube, the fixing members 330 can be implemented by using a core-pulling pin. In this way, the obstruction area of ​​the fixing members 330 on the water spray can be reduced, the dead zone of water spray can be reduced, and the uniformity of spraying can be improved. Preferably, continue to refer to Figure 4 The first isolation part 312 and the second isolation part 322 are completely overlapped to enhance the strength of the fixed connection between the first isolation part 312 and the second isolation part 322, thereby enhancing the overall structural stability of the fixing assembly 300 and realizing reliable fixing and limiting of the first heat exchange tube 100 and the second heat exchange tube 200.

[0053] refer to Figure 5 The first isolation section 312 has several first notches (not shown) whose positions correspond one-to-one with the first positioning holes 313. The first notches are integrally connected with the corresponding first positioning holes 313. The first straight pipe section 110 is set tightly against the second isolation section 322 through the first notches. (Continue to refer to...) Figure 5 as well as Figure 4 The second isolation section 322 is provided with several second notches 325 that correspond one-to-one with the second positioning holes 323. The second notches 325 are integrally connected with the corresponding second positioning holes 323. The second straight pipe section 210 is set close to the first isolation section 312 through the second notches 325.

[0054] Based on this structure, the first heat exchange tube 100 and the second heat exchange tube 200 are separated radially only by the second isolation part 322, and the second heat exchange tube 200 and the first heat exchange tube 100 are separated radially only by the first isolation part 312. This can improve the compact layout of the first heat exchange tube 100 and the second heat exchange tube 200 in the radial direction and reduce the space occupied by the heat exchange unit.

[0055] refer to Figure 4 , 5The first positioning member further includes a first limiting portion 314 extending in the vertical direction. The first limiting portion 314 is located radially outside the first straight pipe section 110 and is connected at a right angle to the first positioning portion 311. The second positioning member further includes a second limiting portion 324 extending in the vertical direction. The second limiting portion 324 is located radially outside the second straight pipe section 210 and is connected at a right angle to the second positioning portion 321. It is easy to understand that the first limiting portion 314 and the second limiting portion 324 can improve the overall structural strength of the fixing assembly 300 and provide radial limiting for the first heat exchange tube 100 and the second heat exchange tube 200, thereby improving the positioning stability of the first heat exchange tube 100 and the second heat exchange tube 200. To make the structure compact, in a preferred embodiment, both the first limiting portion 314 and the second limiting portion 324 are made of thin metal plates.

[0056] refer to Figure 1 , Figure 3 In order to achieve a more compact layout, in some embodiments, the fixing component 300 includes a first type of fixing component 300 and a second type of fixing component 300. The first type of fixing component 300 is used to fix the middle section of the first straight pipe segment 110 and the middle section of the second straight pipe segment 210. The second type of fixing component 300 is disposed near the first U-shaped pipe segment 120 and the second U-shaped pipe segment 220 and is used to fix the portions near both ends of the first straight pipe segment 110 and the second straight pipe segment 210.

[0057] refer to Figure 5 The second type of fixing component 300 includes a limiting member 340 having an extending length in the vertical direction. The limiting member 340 is disposed outside the first U-shaped tube segment 120 and the second U-shaped tube segment 220, and is connected at a right angle to the first limiting portion 314. In this embodiment, reference... Figure 2-5 The first type of fixing component 300 includes at least a first isolation part 312, a first positioning part 311, a second isolation part 322, and a second positioning part 321. It may also include a first limiting part 314 and a second limiting part 324. To improve positioning stability, the second type of fixing component 300 may further include the aforementioned limiting member 340, based on the first type of fixing component 300. (Continuing with reference...) Figure 3 , 5 The limiting member 340 abuts against the outer edges of the first U-shaped tube segment 120 and the second U-shaped tube segment 220 from the outside, thereby restricting the axial movement of the first heat exchange tube 100 and the second heat exchange tube 200, preventing the first heat exchange tube 100 and the second heat exchange tube 200 from separating along the length of the straight tube and reducing loosening, thus improving the positioning stability of the first heat exchange tube 100 and the second heat exchange tube 200. In a preferred embodiment, the limiting member 340 adopts a thin plate structure, making the heat exchange unit lightweight as a whole.

[0058] Continue to refer to Figure 3 , 5 In some embodiments, in order to improve the airflow inside and outside the heat exchange unit, the limiting member 340 is also provided with a hollow structure 341. When multiple heat exchange units are installed inside the frame structure of the condenser, the hollow structure 341 can promote the circulation of air inside and outside the heat exchange unit and improve the heat dissipation performance.

[0059] Furthermore, in order to improve the overall structural strength, for the first type of fixing component 300, the first positioning member is integrally formed by the first isolation part 312, the first positioning part 311, and the first limiting part 314, and the second positioning member is integrally formed by the second isolation part 322, the second positioning part 321, and the second limiting part 324; for the second type of fixing component 300, the first positioning member is integrally formed by the first isolation part 312, the first positioning part 311, the first limiting part 314, and the limiting member 340, and the second positioning member is integrally formed by the second isolation part 322, the second positioning part 321, and the second limiting part 324.

[0060] refer to Figure 1 The first heat exchange tube 100 has a first front opening 130 and a first end opening 140 at both ends, and the second heat exchange tube 200 has a second front opening 230 and a second end opening 240 at both ends. The first front opening 130 and the second front opening 230 are located on the same side of the heat exchange unit and are close to each other, as are the first end opening 140 and the second end opening 240. This facilitates the connection of the first front opening 130 and the second front opening 230 of the heat exchange unit to the same gas collection device, and also facilitates the connection of the first end opening 140 and the second end opening 240 to the same liquid collection device, significantly reducing the complexity of the pipeline layout.

[0061] In a preferred embodiment, the first front opening 130, the first end opening 140, the second front opening 230, and the second end opening 240 are all located on the same side of the heat exchange unit. This allows the condenser's gas collecting device and liquid collecting device to be arranged on the same side, further reducing piping complexity and optimizing the condenser's structural layout.

[0062] refer to Figure 1 In order to facilitate connection with the gas collection device and the liquid collection device, the first front opening 130, the first end opening 140, the second front opening 230, and the second end opening 240 all extend outward to form fixing components 300.

[0063] For specific usage, please refer to... Figure 2In the heat exchange unit of this utility model, from a top-down perspective, the first positioning part 311, the first isolation part 312, the second positioning part 321, the second isolation part 322, the first limiting part 314, the second limiting part 324, and the limiting member 340 all have only a cross-section of thickness. When water is sprayed onto the heat exchange unit from top to bottom for cooling, the cooling water is only blocked by the thickness of the first positioning part 311 and the second positioning part 321, which significantly reduces the dead zone of water spraying. Furthermore, the first heat exchange tube 100 and the second heat exchange tube 200 are arranged in an alternating manner to improve the uniformity and coverage of the water film, thereby improving the heat exchange performance. In this design, a first notch communicating with the first positioning hole 313 is provided in the first isolation part 311. By setting the diameter of the first positioning hole 313 to be equivalent to the diameter of the first heat exchange tube 100, the first heat exchange tube 100 can be positioned in the first positioning hole 313, and the first straight tube section 210 is directly attached to the second isolation part 322 through the first notch. Similarly, a second notch 325 communicating with the second positioning hole 323 is provided in the second isolation part 312. By setting the diameter of the second positioning hole 323 to be equivalent to the diameter of the second heat exchange tube 200, the second heat exchange tube 200 can be positioned in the second positioning hole 323, and the second straight tube section 210 is directly attached to the second isolation part 322 through the second notch 325. In this way, the radial distance between the first heat exchange tube 100 and the second heat exchange tube 200 is greatly shortened, the overall size of the heat exchange unit is reduced, and the heat exchange performance of the heat exchange unit under the same volume is improved. In addition, the present invention also improves the overall structural strength of the fixing component 300 and enhances the fixing and limiting performance of the first heat exchange tube 100 and the second heat exchange tube 200 through the synergistic effect of the first limiting part 314, the second limiting part 324 and the limiting member 340, which helps the water to form a stable and uniform water film in the heat exchange unit.

[0067] The heat exchange unit 10 is supported and fixed in the internal space of the frame 20, and the heat exchange units 10 are arranged parallel to each other and spaced apart.

[0068] The first front opening 130 and the second front opening 230 of each heat exchange unit 10 are connected to the gas collecting pipe, and the first end opening 140 and the second end opening 240 of each heat exchange unit 10 are connected to the liquid collecting pipe.

[0069] In practice, each heat exchange unit 10 is arranged in a parallel and spaced manner along the radial direction of the first straight pipe section and the second straight pipe section. Furthermore, adjacent heat exchange units 10 are arranged with the first heat exchange tube 100 and the second heat exchange tube 200 adjacent to each other, so that all heat exchange tubes are arranged in a parallel and staggered manner.

[0070] In specific implementation, the first front opening 130 and the second front opening 230 of each heat exchange unit 10 are located above the corresponding first end opening 140 and the corresponding second end opening 240, and the gas collection chamber 30 and the liquid collection chamber 40 are arranged vertically.

[0071] Continue to refer to Figure 6 The gas collecting chamber 30 is equipped with an air inlet pipe 31, and the liquid collecting chamber 40 is equipped with a liquid supply pipe 41. In actual use, the high-temperature gas from the outside is first transported to the gas collecting chamber 30 through the air inlet pipe 31, and then sent from the gas collecting chamber 30 to the heat exchange unit 10. The high-temperature gas is cooled and condensed into liquid by the heat exchange unit 10 and transported to the liquid collecting chamber 40, and then supplied to the end of the heat exchange through the liquid supply pipe 41.
