Description

Technical Field

[0001] This invention relates to the field of heat exchanger technology, and more particularly to a support assembly for a heat exchanger finned tube and a heat exchanger using the support assembly. Background Technology

[0002] A heat exchanger is a device that transfers part of the heat from a hot fluid to a cold fluid. Heat exchangers are common equipment in many industrial sectors, including chemical, petroleum, power, food, and others, and play a vital role in production. In chemical production, air coolers are widely used as heaters, coolers, condensers, evaporators, and reboilers. Among these, air coolers (or simply air coolers) use ambient air as the cooling medium and are the most commonly used heat exchange equipment for condensation and cooling in petrochemical and oil and gas processing. Existing air coolers generally consist of finned tubes, tube boxes, fans, louvers, and frames. However, existing air coolers have the following problems in the assembly of the finned tubes:

[0003] 1. The finned tubes in the air cooler are relatively long. The two ends of the finned tubes are fixedly assembled to the two tube plates of the air cooler tube box. There is no support structure in the middle of the finned tube. The middle of the finned tube will bend and droop downward due to the weight of the finned tube, which makes it easy for adjacent finned tubes to stick together, affecting airflow and reducing the cooling effect.

[0004] 2. The bending and sagging length of the winding tube located in the next layer will definitely be affected by the winding tube in the previous layer. Therefore, the degree of bending and sagging of each layer of winding tube is more serious from top to bottom. The winding tube at the bottom layer will definitely have the most severe bending and sagging. The winding tube is prone to damage when it is in a bent state for a long time, which reduces the service life of the winding tube.

[0005] 3. When the air cooler is working, the finned tubes will vibrate. If the finned tubes are not individually supported, they will collide with each other, causing damage to the finned tubes and loud cooling noise.

[0006] 4. The existing support components are a single-piece structure. Each support component has multiple through holes for supporting the finned tubes corresponding to the mounting holes on the tube sheet, which makes assembly and maintenance very inconvenient. Moreover, due to the fixed structure of the support components, they cannot be used with various air coolers, resulting in poor practicality.

[0007] 5. Existing support components are generally made of carbon steel, not only because carbon steel is relatively hard and easily damages the winding tube, but also because carbon steel has a relatively high production cost.

[0008] In view of this, the inventors, in order to address the numerous deficiencies and inconveniences caused by the imperfections in the design of the above-mentioned finned tube support structure and air cooler structure, have deeply conceived, actively researched, improved, and tested the design, and thus developed this invention. Summary of the Invention

[0009] The purpose of this invention is to provide a support assembly for a heat exchanger finned tube. The troughs of the lower and middle corrugated bodies support the middle section of the finned tube, resulting in a more stable support structure that prevents the finned tube from bending and sagging, ensuring each finned tube is horizontal, allowing for uniform airflow and better cooling. Furthermore, it can be freely assembled or disassembled, making operation very convenient. Multiple middle support components can be freely assembled to support multiple layers of finned tubes according to the specific needs of the heat exchanger, demonstrating good practicality.

[0010] Another objective of this invention is to provide a heat exchanger employing this support assembly, which supports each finned tube horizontally, resulting in a stable support structure and improved cooling performance of the heat exchanger.

[0011] To achieve the above objectives, the solution of the present invention is:

[0012] A support assembly for a heat exchanger finned tube includes a lower support and at least one middle support. The lower support has a lower corrugated body and multiple lower support plates extending upward from the midpoint of the crests of the lower corrugated body. The middle support has a middle corrugated body, multiple upper middle support plates extending upward from the midpoint of the crests of the middle corrugated body, and multiple lower middle support plates extending downward from the midpoint of the troughs of the middle corrugated body. The middle support is stacked on the lower support, and the lower support plates and the lower middle support plates are connected by male and female fasteners, with the abutting connection points of the lower support plates and the lower middle support plates abutting against the sidewall of the finned tube. The troughs of the lower corrugated body and the middle corrugated body are used to support the finned tube.

[0013] The support assembly includes at least two central support members. The troughs of the central support members in odd-numbered layers and the crests of the central support members in even-numbered layers are arranged in a one-to-one correspondence. The troughs of the lower support members and the crests of the lowest-level central support members are also arranged in a one-to-one correspondence. The upper central support plate and the lower central support plate are assembled and connected by male and female buckles. The abutting connection between the upper central support plate and the lower central support plate is abutted against the side wall of the winding tube.

[0014] The support assembly also has an upper support member, which has an upper corrugated body and multiple upper support plates extending downward from the middle of the troughs of the upper corrugated body; the upper support members are stacked and assembled above the uppermost middle support member, and the crests of the upper support members and the troughs of the uppermost middle support members are arranged in a one-to-one correspondence; and the middle upper support plate and the upper support plate are assembled and connected by male and female buckles, and the abutting connection between the middle upper support plate and the upper support plate is abutting against the side wall of the winding tube.

[0015] The yin-yang buckle has a yin buckle and a yang buckle. The lower support plate and the middle upper support plate are provided with the yin buckle, and the middle lower support plate and the upper support plate are provided with the yang buckle; or, the lower support plate and the middle upper support plate are provided with the yang buckle, and the middle lower support plate and the upper support plate are provided with the yin buckle.

[0016] The female buckle is a through groove, and the male buckle is a pusher post that is inserted into the through groove; the bottom wall of the through groove is an arc wall forming an arc through groove, and the two side walls of the through groove gradually extend from both sides of the arc wall towards the groove opening to form a trumpet-shaped slot, and the connection between the two side walls and the arc wall is a first necking section; the pusher post has a cylindrical section inserted into the arc through groove and a conical section inserted into the slot, and the connection between the cylindrical section and the conical section is a second necking section.

[0017] The lower, middle, and upper corrugated bodies have an arc segment in the middle and two straight segments on either side of the arc segment on the inner sidewalls at the crest and trough positions. The trough of the lower support member, the crest of the middle support member, and the lower support plates and lower middle support plates on the left and right sides form a hexagonal perforation for the winding tube to pass through. The trough of the lower middle support member, the crest of the upper middle support member, and the upper middle support plates and lower middle support plates on the left and right sides form a hexagonal perforation for the winding tube to pass through. The crest of the upper support member, the trough of the middle support member, and the upper upper support plates and upper middle support plates on the left and right sides form a hexagonal perforation for the winding tube to pass through. The tube wall of each winding tube forms four triangular stability cavities in the corresponding hexagonal perforation.

[0018] The lower wave pattern body, the middle wave pattern body, and the upper wave pattern body are all arc segments located at wave crests at one end and arc segments located at wave troughs at the other end.

[0019] The lower, middle, and upper corrugated bodies are provided with reinforcing ribs on the arc segments at the crest positions. The reinforcing ribs extend downward from the arc surface, and the bottom ends of the reinforcing ribs are connected to the junction of the arc segment and the straight segment. The reinforcing ribs are located on one edge of the arc segment.

[0020] The lower support, middle support, and upper support are made of nylon.

[0021] A heat exchanger employing the aforementioned heat exchanger finned tube support assembly includes a housing, multiple finned tubes housed within the housing, and a support assembly. Multiple bottom support channels are spaced apart along the length of the finned tubes on two opposite side plates of the housing. The two ends of each bottom support channel are welded to the side plates of the housing. Lower support members are fixed to the bottom support channel by self-tapping screws, and middle support members are stacked sequentially upwards on the lower support members fixed to the bottom support channel. The locking positions of the lower support members and the bottom support channel are at the troughs of the lower corrugated body.

[0022] With the above structure, the support assembly of the heat exchanger finned tube of the present invention uses the troughs of the lower corrugated body and the middle corrugated body to support the middle part of the finned tube, and the crest of the lower corrugated body is supported on the plane in an arch shape, which can firmly assemble the middle corrugated body above the lower corrugated body. The support structure of the finned tube is more stable, which can prevent the finned tube from bending and sagging, ensure that each finned tube is in a horizontal state, so that the air flow is uniform and the cooling effect is better. Moreover, the lower support plate, the middle upper support plate and the middle lower support plate are separated between the left and right adjacent finned tubes, which can support each finned tube individually, making the support structure more stable, avoiding collision damage between the finned tubes, and extending the service life of the finned tubes. In addition, the support assembly is composed of a lower support and multiple middle support components, which can be freely assembled or disassembled, making it very convenient for assembly and maintenance. Furthermore, multiple middle support components can be freely assembled to support multiple layers of finned tubes according to the specific needs of the heat exchanger, which has good practicality.

[0023] The heat exchanger of this invention utilizes the aforementioned support components to assemble and support the finned tubes. During assembly, the lower support member is first locked to the bottom of the heat exchanger housing, with the crests of the lower corrugated body forming an arch-like support at the bottom of the housing, ensuring a stable support structure. A layer of finned tubes is then installed on the lower support member, with the lower support plate located between two adjacent finned tubes. Next, the middle support member is assembled onto the lower support member, with the lower middle support plate and the lower support plate abutting against each other and located between two adjacent finned tubes. A layer of finned tubes is also installed on the middle support member, with the upper middle support plate located between two adjacent finned tubes. Multiple middle support members can be assembled on the middle support member as needed, with each middle support member capable of assembling a layer of finned tubes. The upper middle support plate and the lower middle support plate abut against each other and are located between two adjacent finned tubes. The heat exchanger of this invention has the following advantages:

[0024] 1. Multiple support components are provided along the length of the finned tube in the heat exchanger. These components support the middle of each finned tube, keeping each finned tube horizontal and parallel. This prevents the finned tubes from bending, drooping, and sticking together in the middle, ensuring uniform airflow and good cooling effect.

[0025] 2. The lower corrugated body of the support component of the present invention has an arch-shaped support on the plane, which can make the middle corrugated body firmly assembled on the upper part of the lower corrugated body. It can support each layer of coiled tubes, avoid the upper and lower layers of coiled tubes from affecting each other and causing the coiled tubes to be in a bent state for a long time and be damaged, thus extending the service life of the coiled tubes and thus extending the service life of the heat exchanger.

[0026] 3. The support structure of the present invention is composed of a lower support component and a middle support component. The lower support component and the middle support component are connected by male and female buckles. The assembly structure is simple and can be freely combined, assembled or disassembled, making it very convenient for assembly and maintenance. Moreover, multiple middle support components can be freely assembled to support multi-layer wound tubes according to the specific needs of the heat exchanger, which has good practicality.

[0027] 4. When the heat exchanger is working, the support structure can support each layer of finned tubes and separate each finned tube for support, so as to avoid the finned tubes colliding with each other and causing damage to the finned tubes and excessive cooling noise.

[0028] 5. The support component of this invention is made of nylon material. Nylon material is softer than carbon steel material, can undergo elastic deformation, is less likely to damage the winding tube, and has a lower production cost. Attached Figure Description

Detailed Implementation

[0044] To further explain the technical solution of the present invention, the present invention will be described in detail below through specific embodiments.

[0045] Please see Figures 1 to 12 This invention discloses a support assembly for a heat exchanger finned tube. The support assembly has a lower support 1 and at least one middle support 2.

The troughs of the lower corrugated body 11 and the middle corrugated body 21 are used to support the finned tube 10.

[0046] The support assembly for the heat exchanger finned tubes of this invention utilizes the troughs of the lower corrugated body 11 and the middle corrugated body 21 to support the middle part of the finned tube 10. The crests of the lower corrugated body 11 form an arch-like support on the plane, allowing the middle corrugated body 21 to be firmly assembled above the lower corrugated body 11. This makes the support structure of the finned tube 10 more stable, preventing the finned tube 10 from bending or sagging, ensuring that each finned tube 10 is in a horizontal state, allowing for uniform airflow and better cooling effect. Furthermore, the lower support plate 12 and the middle upper support... Plate 22 and lower support plate 23 are separated between two adjacent finned tubes 10 on the left and right sides, which can support each finned tube 10 separately, making the support structure more stable, avoiding collision damage between the finned tubes 10 and extending the service life of the finned tubes 10; moreover, the support assembly is composed of a lower support 1 and multiple middle support 2, which can be freely assembled or disassembled, making it very convenient for assembly and maintenance; moreover, multiple middle support 2 can be freely assembled to support multiple layers of finned tubes 10 according to the specific needs of the heat exchanger, which is highly practical.

The assembly structure of the support assembly is firm, and the support effect of the coiled tube 10 is good.

[0049] The male and female buckle of the present invention has a female buckle and a male buckle. The lower support plate 12 and the middle upper support plate 22 are provided with the female buckle, and the middle lower support plate 23 and the upper support plate 32 are provided with the male buckle; or, the lower support plate 12 and the middle upper support plate 22 are provided with the male buckle, and the middle lower support plate 23 and the upper support plate 32 are provided with the female buckle; the lower support member 1, the middle support member 2, and the upper support member 3 are assembled and connected by the male and female buckles, making the assembly structure simpler and more robust.

The cylindrical segment 1221 and the conical segment 1222 are fitted into the slot, and the connection between the cylindrical segment 1221 and the conical segment 1222 is a second necked segment 1223; in the mating structure of the through slot 121 and the abutment post 122, the through slot 121 and the abutment post 122 are respectively provided with a first necked segment 1213 and a second necked segment 1223, so that the through slot 121 and the abutment post 122 are not easy to fall out after being fitted together, and the fitting structure is more secure.

[0051] The through groove 121 of the present invention is recessed downward from the top surfaces of the lower support plate 12 and the middle upper support plate 22, and the abutment column 122 extends downward from the bottom surfaces of the middle lower support plate 23 and the upper support plate 32.

[0052] The through groove 121 of the present invention has a large-diameter through groove near the bottom and a small-diameter through groove near the opening; the abutment column 122 has a large-head column near the outer end and a large-head column near the inner end. The large-head column is inserted into the large-diameter through groove and the small-head column is inserted into the small-diameter through groove, making the assembly structure more robust.

[0053] The lower corrugated body 11, the middle corrugated body 21, the upper corrugated body 31, and the lower support plate 12 of the present invention have the same thickness in the horizontal direction, and the lower support plate 12, the middle upper support plate 22, the middle lower support plate 23, and the upper support plate 32 have the same vertical height; the through groove 121 and the abutment column 122 have the same thickness in the horizontal direction as the lower support plate 12; when the support members 1 are stacked up and down, the abutment column 122 is pressed into the through groove 121 from the opening of the through groove 121 and is locked in the through groove 121, or the abutment column 122 is slid into the through groove 121 from one side of the through groove 121. The assembly structure of the through groove 121 and the abutment column is simple, thereby making the assembly operation of the two support members 1 simple and the assembly firm.

[0054] The lower corrugated body 11, the middle corrugated body 21, and the upper corrugated body 31 of the present invention have an arc segment 111 located in the middle and two straight segments 112 located on both sides of the arc segment on the inner sidewall at the crest and trough positions, respectively; the inner sidewall of the arc segment 111 and the two straight segments 112 at the crest and trough positions is a non-circular arc structure, and the trough of the lower support member 1, the crest of the middle support member 2, and the lower support plates 12 on the left and right sides and the lower support plate 23 in the middle form a hexagonal perforation 20 for the winding tube 10 to pass through; the lower layer middle The trough of the lower support member 2, the crest of the upper middle support member 2, and the middle upper support plate 22 and middle lower support plate 23 on the left and right sides form a hexagonal perforation 20 through which the wrapping tube 10 passes; the crest of the upper support member 3, the trough of the middle support member 2, and the upper support plate 32 and middle upper support plate 22 on the left and right sides form a hexagonal perforation 20 for the wrapping tube 10 to pass through, and the tube wall of each wrapping tube 10 forms four triangular stability cavities 100 in the corresponding hexagonal perforation 20; the support structure of the wrapping tube 10 is more stable and can prevent the wrapping tube 10 from bending and sagging.

[0055] The lower corrugated body 11, the middle corrugated body 21, and the upper corrugated body 31 of the present invention have an arc segment 111 at one end located at the crest of the wave and an arc segment 112 at the trough of the wave at the other end. When the two lower support members 1 are connected side by side, the crest of one lower corrugated body 11 connects to the trough of the other lower corrugated body 11, which can directly connect the two lower support members 1 to form a continuous lower corrugated body 11, thereby extending the length of the lower corrugated body 11. Alternatively, multiple middle corrugated bodies 21 and multiple upper corrugated bodies 31 can be connected side by side to extend the middle corrugated body 21 and the upper corrugated body 31. They can be freely combined and extended for use, making them more applicable.

[0056] The reinforcing ribs 201 are provided at the crest and / or trough positions of the lower corrugated body 11, the middle corrugated body 21 and the upper corrugated body 31 of the present invention. The reinforcing ribs 201 can not only strengthen the structural strength at the crest and trough positions, but also abut against the tube wall of the winding tube 10, so that the winding tube 10 can be interference-fitted into the perforation 20 formed by the support structure, making the support structure of the winding tube 10 more stable.

[0057] The lower corrugated body 11, the middle corrugated body 21, and the upper corrugated body 31 of the present invention are provided with reinforcing ribs 201 at the arc segments 111 at the crest positions; the bottom of the winding tube 10 is supported at the trough positions of the lower corrugated body 11 and the middle corrugated body 21, and the top of the winding tube 10 abuts against the crest positions of the middle corrugated body 21 and the upper corrugated body 31; the supporting force of the winding tube 10 is located at the trough position, therefore, providing the reinforcing ribs 201 at the crest positions will not affect the support of the winding tube 10 at the trough positions of the lower corrugated body 11 and the middle corrugated body 21.

[0058] The reinforcing rib 201 of the present invention extends downward from the arc surface of the arc segment 111 at the crest position. The bottom two ends of the reinforcing rib 201 are connected to the connection between the arc segment 111 and the straight segment 112, and the reinforcing rib 201 is located on one side edge of the arc segment 111. The arc-shaped plate structure of the reinforcing rib 201 combined with the arc segment 111 at the crest position can enhance the structural strength at the crest position. The reinforcing rib 201 abuts against the tube wall of the winding tube 10, allowing the winding tube 10 to be interference-fitted into the upper and lower perforations, making the support structure of the winding tube 10 more stable.

[0059] The lower support 1, middle support 2, and upper support 3 of the present invention are made of nylon. By assembling the support components made of nylon, the nylon material is relatively soft compared to carbon steel and can undergo elastic deformation under stress. When the nylon tube 10 is interference-fitted with the support structure, the support structure is less likely to damage the nylon tube 10. Moreover, the production cost of nylon is relatively low. Furthermore, a reinforcing rib 201 is provided in the perforation 20. The reinforcing rib 201 not only strengthens the support structure but also abuts against the outer wall of the nylon tube 10, making the assembly of the nylon tube 10 and the support structure more secure. The support structure of the nylon tube 10 has a good effect, which can prevent the nylon tube 10 from bending and sagging, and improve the cooling effect of the heat exchanger.

The heat exchanger includes a housing, a plurality of finned tubes 10 installed inside the housing, and a support assembly for the finned tubes. A plurality of bottom support channels are spaced apart along the length of the finned tubes 10 on two opposite side plates of the housing.

The middle support member 2 is stacked on top of the component 1 in sequence; the locking position of the lower support member 1 and the bottom support channel steel is the trough position of the lower corrugated body 11; multiple top support channel steels are arranged at intervals along the length direction of the winding tube 10 on the two opposite side plates of the box body, and the two ends of the top support channel steel are welded to the two side plates of the box body respectively; the upper support member 3 is fixed to the top plate support channel steel by self-tapping screws; the locking position of the upper support member 3 and the top support channel steel is the crest position of the upper corrugated body 31.

[0061] The support assembly of the present invention has a lower support member 1, at least one middle support member 2, and an upper support member 3. The lower support member 1 has a lower corrugated body 11 and a plurality of lower support plates 12 extending upward from the middle position of the crest of the lower corrugated body 11. The middle support member 2 has a middle corrugated body 21, a plurality of middle upper support plates 22 extending upward from the middle position of the crest of the middle corrugated body 21, and a plurality of middle lower support plates 23 extending downward from the middle position of the trough of the middle corrugated body 21. The upper support member 3 has an upper corrugated body 31 and a plurality of upper support plates 32 extending downward from the middle position of the trough of the upper corrugated body 31. The middle support member 2 is stacked on the lower support member 1, and the lower support plates 12 and the middle lower support plates 23 are connected by male and female fasteners. The lower support plate 12 and the middle lower support plate 23 are connected and their abutting connection points are abutted against the side wall of the coiled tube 10. The trough positions of the lower corrugated body 11 and the middle corrugated body 21 are used to support the coiled tube 10. The upper support member 3 is stacked and assembled above the middle support member 2, and the crests of the upper support member 3 and the troughs of the uppermost middle support member 2 are set one-to-one. The middle upper support plate 22 and the upper support plate 32 are assembled and connected by male and female buckles, and their abutting connection points are abutted against the side wall of the coiled tube 10. The lower support member 1 and the upper support member 3 can be locked with the heat exchanger housing, and the middle support member 2 is fixed and limited between the lower support member 1 and the upper support member 3. The support assembly structure is firm and the support effect of the coiled tube 10 is good.

[0062] The heat exchanger of the present invention utilizes the aforementioned support assembly to assemble and support the finned tubes 10. During assembly of the finned tubes 10, the lower support member 1 is first locked to the bottom of the heat exchanger housing, with the crests of the lower corrugated body 11 forming an arch-like support at the bottom of the housing, ensuring a stable support structure. A layer of finned tubes 10 is then installed on the lower support member 1, with the lower support plate 12 located between two adjacent finned tubes 10. Next, the middle support member 2 is assembled onto the lower support member 1, and the middle lower support plate 23 and the lower... The support plate 12 is abutted and located between two adjacent finned tubes 10, and a layer of finned tubes 10 is installed on the middle support member 2, with the upper middle support plate 22 located between two adjacent finned tubes 10. Multiple middle support members 2 can be assembled on the middle support member 2 as needed, and a layer of finned tubes 10 can be assembled on each middle support member 2. The upper middle support plate 22 and the lower middle support plate 23 are abutted and located between two adjacent finned tubes 10. The heat exchanger of the present invention has the following advantages:

[0063] 1. Multiple support components are provided along the length of the finned tube 10 in the heat exchanger, which can support the middle of each finned tube 10, keep each finned tube 10 in a horizontal and parallel state, prevent the middle of the finned tube 10 from bending, drooping and sticking together, so that the air flow is uniform and the cooling effect is good.

[0064] 2. The lower corrugated body 11 of the support component of the present invention has its crests arched and supported on the plane, which can make the middle corrugated body 21 firmly assembled above the lower corrugated body 11. It can support each layer of the coiled tube 10, avoid the upper and lower layers of coiled tubes from affecting each other and causing the coiled tubes to be in a bent state for a long time and be damaged, thus extending the service life of the coiled tubes and thus extending the service life of the heat exchanger.

[0065] 3. The support structure of the present invention is composed of a lower support member 1, a middle support member 2, and an upper support member 3. The lower support member 1, the middle support member 2, and the upper support member 3 are connected by male and female buckles. The assembly structure is simple and can be freely combined, assembled, or disassembled, making it very convenient for assembly and maintenance. Moreover, multiple middle support members 2 can be freely assembled to support the multi-layer wound tube 10 according to the specific needs of the heat exchanger, which has good practicality.

[0066] 4. When the heat exchanger is working, the support structure can support each layer of finned tube 10 and separate each finned tube 10 for support, so as to avoid the finned tubes 10 colliding with each other and causing damage to the finned tubes and excessive cooling noise.

[0067] 5. The support component of this invention is made of nylon. Nylon is softer than carbon steel, allowing for elastic deformation and reducing the risk of damage to the finned tube.
