Description

Technical Field

[0001] The utility model relates to the technical field of heat exchangers, in particular to a fin-tube heat exchanger capable of reducing flow resistance and improving liquid flow speed. Background Art

[0002] Fin-tube heat exchanger is a highly efficient heat exchange equipment, widely used in various industrial fields. Its basic heat transfer element is finned tube, which consists of base tube and fin. The base tube is usually round tube, but also oval tube and flat tube. The surface structure of fin includes flat fin, discontinuous fin, corrugated fin and perforated fin, among which corrugated fin and perforated fin belong to high-efficiency heat exchange type. The structure of finned tube heat exchanger can be divided into two basic types: longitudinal and radial, as well as other derivative types. The manufacturing process includes integral finned tube, welded finned tube, high-frequency welded finned tube and mechanically connected finned tube.

[0003] The existing fin-tube heat exchanger has a relatively fixed fin distribution, which makes it inconvenient to add fins, resulting in poor use effect.

[0004] Therefore, we propose a fin-tube heat exchanger that can increase the adjustment of the fins. Increasing the fin spacing can reduce the friction resistance when the fluid flows through the fins, but it will also reduce the heat exchange area. A balance is found between reducing resistance and maintaining sufficient heat exchange area to improve the use effect of the heat exchanger, reduce flow resistance and increase liquid flow rate. Utility Model Content

[0005] The utility model aims to provide a fin-tube heat exchanger which reduces flow resistance and improves liquid flow velocity, so as to solve the problems raised in the above-mentioned background technology.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solution: a fin-tube heat exchanger that reduces flow resistance and increases liquid flow speed, comprising a tube body, the outer wall of the tube body being slidably provided with fins, the end of the tube body being connected with a connecting elbow, the outer wall of the tube body being fixedly provided with a plate body, the outer wall of the connecting elbow being sleeved with bolts, and a processing component arranged on the outside of the tube body, the processing component comprising an adding component arranged on the outside of the tube body, and an adjusting component being arranged on the outside of the adding component.

[0007] Preferably, the adding component includes a threaded rod rotatably connected to the outer wall of the plate body, the outer wall of the threaded rod is sleeved with a sleeve plate, the outer wall of the sleeve plate is fixedly mounted with a movable ring, the inner wall of the movable ring is fixedly mounted with a sliding rod, the outer wall of the sliding rod is sleeved with a spring, the outer wall of the sliding rod is slidably mounted with a sleeve block, the outer wall of the sleeve block is fixedly mounted with a clamping block, and a handle is fixedly mounted on the end of the threaded rod away from the plate body.

[0008] Preferably, the adjustment assembly includes a first magnetic ring fixedly mounted on the outer wall of the fin, a second magnetic ring fixedly mounted on the side of the fin away from the first magnetic ring, a sliding ring fixedly mounted on the inner wall of the fin, and a third magnetic ring fixedly mounted on the outer wall of the connecting elbow.

[0009] Preferably, the outer wall of one end of the block away from the inner wall of the movable ring is inclined, and there are twelve blocks, which are divided into two groups and symmetrically distributed about the center line of the sleeve plate. Under the restriction, the fins can be pushed by the blocks to add fins.

[0010] Preferably, one end of the spring is fixedly mounted on the inner wall of the moving ring, and one end of the spring away from the inner wall of the moving ring is fixedly mounted on the outer wall of the sleeve block. Under the elastic action of the spring, the block is reset when it is not squeezed.

[0011] Preferably, the sliding ring is made of a material with a low friction coefficient, and the sliding ring is slidably arranged with the outer wall of the tube body. Under the restriction of the sliding ring, the wear between the fin and the tube body can be reduced.

[0012] Preferably, the first magnetic ring and the second magnetic ring magnetically repel each other, and the second magnetic ring and the third magnetic ring magnetically repel each other. Under this restriction, the spacing between the fins sleeved on the outer wall of the tube body can be made consistent.

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] 1. The fin-tube heat exchanger for reducing flow resistance and increasing liquid flow rate is composed of an additional component as one of its parts. When the fin needs to be adjusted, the handle is turned, and the handle drives the threaded rod to rotate. Since the outer wall of the block contacts the outer wall of the fin, under its restriction, the rotating threaded rod drives the sleeve plate and the movable ring to move in the direction of the plate body. The side of the block away from its inclined surface contacts the outer wall of the fin, pushing the fin. Since the fins are restricted by the magnetic mutual repulsion, the fins can be squeezed and pushed. The bolts are turned to remove the connecting elbow, the fin sleeve is set on the outer wall of the tube body, and then the connecting elbow is installed on the outer wall of the tube body through the bolts. At this time, the handle is reversed to reverse the threaded rod, driving the sleeve plate and the movable ring to move in the direction of the connecting elbow, so that the sliding rod fixedly installed inside the movable ring moves in the direction of the connecting elbow, and the outer wall of the sliding rod slides The set sleeve block and the clamping block move accordingly, so that the inclined surface of the clamping block contacts and squeezes the outer wall of the fin, so that the sleeve block fixedly installed on the outer wall of the clamping block slides on the outer wall of the slide rod, and squeezes the spring sleeved on the outer wall of the slide rod, so that the side of the clamping block away from its inclined surface contacts the outer wall of the fin. Due to the magnetic repulsion between the fin and the third magnetic ring fixedly installed on the outer wall of the connecting elbow, under its restriction, it is easy to make the side of the clamping block away from its inclined surface contact the outer wall of the newly set fin, and rotate the threaded rod to move the sleeve plate and the movable ring, driving the clamping block to move toward the plate body. The clamping block pushes the newly set fin to add the fin. This structure can quickly add fins. Increasing the fin spacing can reduce the friction resistance when the fluid flows through the fins, but it will also reduce the heat exchange area, and find a balance between reducing resistance and maintaining sufficient heat exchange area.

[0015] 2. The fin-tube heat exchanger for reducing flow resistance and increasing liquid flow speed is composed of an adjusting component as one of its components. When the block contacts the fin away from the inclined side thereof, the fin is pushed to slide on the outer wall of the tube body, and the first magnetic ring fixedly installed on the outer wall of the first fin and the second magnetic ring fixedly installed on the outer wall of the second fin are close to each other. Under the restriction of magnetic mutual repulsion, the fins are pushed, squeezed and gathered together. At this time, the connecting elbow and the bolts are removed, and new fins are sleeved on the outer wall of the tube body, and then the connecting elbow and the bolts are installed. Under the magnetic force of the third magnetic ring fixedly installed on the outer wall of the connecting elbow, the new fin is pushed toward the block, and the threaded rod is reversed so that the inclined surface of the block contacts and squeezes the outer wall of the new fin, and the new fin is pushed toward the original fin. Under the restriction of magnetic mutual repulsion, the spacing between the fins can be made consistent, so that the heat exchange effect is better. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0023] In order to have a clearer understanding of the technical features, purposes and effects of the utility model, the specific implementation methods of the utility model are now described with reference to the accompanying drawings.

[0024] Example 1

[0025] The preferred embodiment of the fin-tube heat exchanger provided by the utility model for reducing flow resistance and increasing liquid flow speed is as follows: Figures 1 to 6 As shown: a fin-tube heat exchanger for reducing flow resistance and increasing liquid flow velocity, comprising a tube body 1;

[0026] The outer wall of the tube body 1 is slidably provided with fins 2;

[0027] The end of the pipe body 1 is connected with a connecting elbow 3;

[0028] A plate body 4 is fixedly mounted on the outer wall of the tube body 1;

[0029] The outer wall of the connecting elbow 3 is sleeved with bolts 6;

[0030] And a processing component 5 arranged outside the tube body 1, the processing component 5 includes an adding component 51 arranged outside the tube body 1, the adding component 51 includes a threaded rod 511 rotatably connected to the outer wall of the plate body 4, the outer wall of the threaded rod 511 is sleeved with a sleeve plate 512, the outer wall of the sleeve plate 512 is fixedly installed with a moving ring 513, the inner wall of the moving ring 513 is fixedly installed with a sliding rod 514, the outer wall of the sliding rod 514 is sleeved with a spring 515, the outer wall of the sliding rod 514 is slidably provided with a sleeve block 516, the outer wall of the sleeve block 516 is fixedly installed with a clamping block 517, and the end of the threaded rod 511 away from the plate body 4 is fixedly installed with a handle 518.

[0031] When the fin 2 needs to be adjusted, the handle 518 is rotated, and the handle 518 drives the threaded rod 511 to rotate. Since the outer wall of the block 517 contacts the outer wall of the fin 2, under its restriction, the rotating threaded rod 511 drives the sleeve plate 512 and the movable ring 513 to move toward the plate body 4, and the side of the block 517 away from its inclined surface contacts the outer wall of the fin 2, pushing the fin 2. Since the fins 2 are restricted by the magnetic mutual repulsion, the fin 2 can be squeezed and pushed, and the bolt 6 is rotated to remove the connecting elbow 3, and the fin 2 is sleeved on the outer wall of the tube body 1, and then the connecting elbow 3 is installed on the outer wall of the tube body 1 through the bolt 6. At this time, the handle 518 is reversed to reverse the threaded rod 511, driving the sleeve plate 512 and the movable ring 513 to move in the direction of the connecting elbow 3, so that the sliding rod 514 fixedly installed inside the movable ring 513 moves in the direction of the connecting elbow 3, and the sleeve block 516 and the block 517 slidingly arranged on the outer wall of the sliding rod 514 move with The movement of the block 517 causes the inclined surface to contact and squeeze the outer wall of the fin 2, so that the sleeve block 516 fixedly installed on the outer wall of the block 517 slides on the outer wall of the slide bar 514 and squeezes the spring 515 sleeved on the outer wall of the slide bar 514, so that the side of the block 517 away from its inclined surface contacts the outer wall of the fin 2. Due to the magnetic repulsion between the fin 2 and the third magnetic ring 524 fixedly installed on the outer wall of the connecting elbow 3, under its restriction, it is easy to make the side of the block 517 away from its inclined surface contact the outer wall of the newly sleeved fin 2, rotate the threaded rod 511, so that the sleeve plate 512 and the movable ring 513 move, drive the block 517 to move toward the plate body 4, and the block 517 pushes the newly sleeved fin 2 to add the fin 2. This structure can quickly add the fin 2. Increasing the spacing between the fins 2 can reduce the friction resistance when the fluid flows through the fin 2, but it will also reduce the heat exchange area, and find a balance between reducing resistance and maintaining sufficient heat exchange area.

[0032] Furthermore, the outer wall of one end of the block 517 away from the inner wall of the movable ring 513 is set in an inclined surface. There are twelve blocks 517, which are divided into two groups and are symmetrically distributed about the center line of the sleeve plate 512. Under its limitation, the fin 2 can be pushed by the block 517 to add the fin 2.

[0033] Furthermore, one end of the spring 515 is fixedly installed on the inner wall of the movable ring 513, and the end of the spring 515 away from the inner wall of the movable ring 513 is fixedly installed on the outer wall of the sleeve block 516. Under the elastic action of the spring 515, when the block 517 is not squeezed, the block 517 is reset.

[0034] Example 2

[0035] Based on Example 1, a preferred embodiment of the fin-tube heat exchanger for reducing flow resistance and increasing liquid flow velocity provided by the utility model is as follows: Figures 1 to 6As shown: the adjustment component 52 includes a first magnetic ring 521 fixedly mounted on the outer wall of the fin 2, a second magnetic ring 522 fixedly mounted on the side of the fin 2 away from the first magnetic ring 521, a sliding ring 523 fixedly mounted on the inner wall of the fin 2, and a third magnetic ring 524 fixedly mounted on the outer wall of the connecting elbow 3.

[0036] In this embodiment, when the block 517 is away from the inclined side and contacts the fin 2, the fin 2 is pushed to slide on the outer wall of the tube body 1, and the first magnetic ring 521 fixedly installed on the outer wall of the first fin 2 is close to the second magnetic ring 522 fixedly installed on the outer wall of the second fin 2. Under the restriction of magnetic mutual repulsion, the fin 2 is pushed, squeezed and gathered. At this time, the connecting elbow 3 and the bolt 6 are removed, and the new fin 2 is sleeved on the outer wall of the tube body 1, and then the connecting elbow 3 and the bolt 6 are installed. Under the magnetic force of the third magnetic ring 524 fixedly installed on the outer wall of the connecting elbow 3, the new fin 2 is pushed toward the block 517, and the threaded rod 511 is reversed so that the inclined surface of the block 517 contacts and squeezes the outer wall of the new fin 2, and the new fin 2 is pushed toward the original fin 2 again. Under the restriction of magnetic mutual repulsion, the spacing between the fins 2 can be made consistent, so that the heat exchange effect is better.

[0037] Furthermore, the sliding ring 523 is made of a material with a low friction coefficient, and the sliding ring 523 is slidingly arranged with the outer wall of the tube body 1. Under the restriction of the sliding ring 523, the wear of the fin 2 and the tube body 1 can be reduced.

[0038] In addition, the first magnetic ring 521 and the second magnetic ring 522 magnetically repel each other, and the second magnetic ring 522 and the third magnetic ring 524 magnetically repel each other. Under these restrictions, the spacing between the fins 2 sleeved on the outer wall of the tube body 1 can be made consistent.

[0039] The above is only an illustrative specific implementation method of the utility model, and is not intended to limit the scope of the utility model. Any equivalent changes and modifications made by any technician in this field without departing from the concept and principle of the utility model should fall within the scope of protection of the utility model. It should also be noted that the various components of the utility model are not limited to the above-mentioned overall application. The various technical features described in the specification of the utility model can be selected one by one or multiple ones can be selected and used in combination according to actual needs. Therefore, the utility model should naturally cover other combinations and specific applications related to the utility model points of this case.
