Description

Technical Field

[0001] The present application relates to the technical field of scale cleaning, and in particular to a fin-type heat exchanger that is convenient for cleaning scale. Background Art

[0002] Finned heat exchangers are an enhanced type of heat exchanger that utilizes fins attached to the base tube to increase the heat transfer area and thus improve heat transfer efficiency. They are widely used in air conditioning systems, refrigeration equipment, industrial process control, and other fields. They can be used in various heat exchanger types, such as air-to-air, air-to-water, or water-to-water.

[0003] Existing base pipes are prone to scaling after prolonged use. Scale is a poor conductor of heat, forming an insulating layer on the pipe's inner wall. This reduces the effective transfer of heat to the fluid, thereby reducing heat transfer efficiency. Furthermore, as scale accumulates, the effective cross-sectional area of ​​the pipe decreases, further reducing fluid flow.

[0004] Currently, when cleaning scale inside the base tube, chemical cleaning agents are generally introduced into the fin heat exchanger to soften the scale, and then the softened scale is removed by water flow. However, this method has a relatively complicated operation process and takes a long time to clean the scale. Utility Model Content

[0039] The following is combined with Figure 1-Figure 3 This application is described in further detail.

[0040] An embodiment of the present application discloses a fin-type heat exchanger that is convenient for cleaning scale.

[0041] A fin-type heat exchanger for convenient scale cleaning includes a base tube 1, a mounting base 2, a drive assembly 3, and a brush body 4. The fins are fixedly mounted on the base tube 1, the mounting base 2 is sealingly mounted on the end of the base tube 1, the drive assembly 3 is installed inside the base tube 1, and the drive assembly 3 and the mounting base 2 are rotatably engaged. The brush body 4 is movably mounted on the drive assembly 3.

[0042] The pressure difference formed by the flow of liquid inside the base pipe 1 drives the driving assembly 3 to rotate, and the mounting seat 2 guides the driving assembly 3. During the rotation of the driving assembly 3, the brush body 4 cleans the inner wall of the base pipe 1, thereby improving the convenience of the inner wall of the base pipe 1 and reducing the possibility of scale accumulation on the inner wall of the base pipe 1.

[0043] The mounting base 2 includes a rotating ring 21 , a mounting ring 22 and a connecting unit 3 .

[0044] The rotating ring 21 and the mounting ring 22 are coaxially arranged, and a plurality of connecting units 3 are circumferentially arranged along the axis of the rotating ring 21. In the embodiment of the present application, there are four connecting units 3. Each connecting unit 3 is a connecting plate, and the connecting plate is arranged obliquely.

[0045] The mounting ring 22 is sealed and threadedly connected to the end of the base pipe 1. Under the action of the pressure difference of the liquid flowing inside the base pipe 1, the inclined connecting plate drives the mounting ring 22 to rotate in the direction of tightening with the base pipe 1, thereby improving the connection reliability of the mounting ring 22 and the base pipe 1.

[0046] The driving assembly 3 includes a reference positioning shaft 31 and a pushing unit 32 .

[0047] The reference positioning shaft 31 and the base pipe 1 are coaxially arranged. The two ends of the reference positioning shaft 31 are rotatably matched with the rotating rings 21 at the two ends of the base pipe 1. The reference positioning shaft 31 is guided and limited by the rotating rings 21.

[0048] The pushing unit 32 includes a limiting ring 321 and a pushing blade 322 .

[0049] The limiting ring 321 is coaxially sleeved on the reference positioning shaft 31, and several pushing blades 322 are circumferentially arranged along the axial direction of the limiting ring 321. In the embodiment of the present application, there are five pushing blades 322, and each pushing blade 322 is tilted to facilitate the pressure difference of the liquid during the flow of the liquid to cause the limiting ring 321 and the pushing blade 322 to rotate.

[0050] In order to facilitate the adjustment of the angle of the pushing blade 322 between two adjacent pushing units 32, a number of limiting grooves are opened on the inner wall of the limiting ring 321, and a number of limiting strips 311 are fixedly installed on the reference positioning shaft 31. The number of limiting strips 311 and the number of limiting grooves correspond one to one. The limiting strips 311 are inserted into different limiting grooves to adjust the angle of the pushing blade 322, so that the pushing blades 322 of the number of pushing units 32 are arranged along a spiral line as a whole, so as to further facilitate the rotation of the pushing blade 322 during the flow of liquid.

[0051] The clamping unit 33 is a clamping cylinder 331 , which is threadedly connected to the reference positioning shaft 31 . The two clamping cylinders 331 clamp the plurality of pushing units 32 as a whole, thereby improving the convenience of clamping the pushing units 32 .

[0052] The end of the clamping cylinder 331 is provided with a plurality of protrusions 332, through which the clamping cylinder 331 contacts the mounting seat 2. The plurality of protrusions 332 are distributed circumferentially along the axis of the clamping cylinder 331, and each protrusion 332 is hemispherical, thereby reducing the contact area with the rotating ring 21, thereby facilitating grinding.

[0053] The brush body 4 includes an adjustment plate 41 and a cleaning unit 42 .

[0054] A sliding groove 323 is formed on the pushing blade 322 , and the adjusting plate 41 is placed on the sliding groove 323 . The adjusting plate 41 and the sliding groove 323 are slidably matched.

[0055] The cleaning unit 42 includes a placement plate 421 and brush bristles 422 .

[0056] The placement plate 421 is fixedly mounted on the adjustment plate 41 , and the brush 422 is fixedly mounted on the placement plate 421 . The placement plate 421 slides inside the sliding groove 323 under the centrifugal force that pushes the blade 322 to rotate, and cleans the base pipe 1 through the brush 422 .

[0057] The principle of implementing a fin-type heat exchanger that facilitates scale removal in the present embodiment is as follows: a limiting ring 321 is placed over the reference positioning shaft 31, and a limiting bar 311 is inserted into the limiting groove, so that the push blades 322 of the plurality of push units 32 are arranged in a spiral shape. The adjustment plate 41 is slidably placed within the sliding groove 323 to accommodate base pipes 1 of varying inner diameters. Subsequently, a clamping cylinder 331 is installed over the reference positioning shaft 31, and the plurality of push units 32 are clamped together by the two clamping cylinders 331. The mounting ring 22 is then threadedly connected to both ends of the base pipe 1, and the reference positioning shaft 31 is inserted into the rotating ring 21, so that the protrusion 332 contacts the rotating ring 21.

[0058] During the flow of liquid inside the base tube 1, the pressure difference formed by pushing the blades 322 during the flow of the liquid causes the blades 322 to drive the reference positioning shaft 31 to rotate. Under the action of centrifugal force, the adjustment plate 41 causes the bristles 422 to come into contact with the inner wall of the base tube 1, and the bristles 422 clean the inner wall of the base tube 1, thereby automatically cleaning the base tube 1, improving the convenience of cleaning the inner wall of the base tube 1, and reducing the possibility of scale accumulation on the inner wall of the base tube 1.

[0059] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
