[0002] A heat pipe heat exchanger is an efficient heat energy transfer device. It uses heat pipe technology to achieve heat exchange between two fluids, and these two fluids do not mix directly during the heat exchange process. A heat pipe is a closed tubular structure, and its interior is usually filled with a small amount of working medium, such as water, ammonia or other suitable liquids. The core advantage of heat pipe technology lies in its excellent thermal conductivity and isothermal property, making the heat energy almost lossless during the transfer process.

[0003] In the existing heat pipe heat exchanger convenient for cleaning, a scraper is installed on the heat exchange tube, and the impurities on the heat exchange tube are scraped off by pushing the scraper to move left and right. However, dust and impurities are also likely to accumulate in the U-shaped area of the heat exchange tube. The impurities in the U-shaped area cannot be scraped off only by the scraper moving left and right, which affects the cleaning effect. Other cleaning tools are needed for cleaning, and the operation is relatively cumbersome, thus affecting the cleaning efficiency and being rather inconvenient.

[0004] Therefore, it is necessary to design a heat pipe heat exchanger convenient for cleaning that can conveniently scrape off the impurities in the U-shaped area of the heat exchange tube, has a simple operation, and improves the cleaning efficiency and effect. Content of the Utility Model

Pins are clamped between the box body and the front part of the front end cover, and pins are also clamped between the box body and the front part of the rear end cover. A dust cleaning mechanism is arranged on the horizontal partition board.

[0007] Furthermore, the side doors are both arc-shaped.

[0008] Furthermore, anti-slip pads are provided on the lower sides of the front and rear parts of the front end cover and the lower sides of the front and rear parts of the rear end cover.

[0009] Furthermore, the dust cleaning mechanism includes a trackless cylinder, a dust brushing plate, a rotary scraping plate and a torsion spring.

Specific embodiments

[0021] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0022] A heat pipe heat exchanger that is convenient for cleaning, as Figure 1 and Figure 2 shown, includes a front end cover 1, a side door 11, a box body 2, a rear end cover 3, a horizontal partition board 4, a vertical partition board 41, a heat exchange tube 5, a bolt 6 and a dust cleaning mechanism 7. The box body 2 is clamped on the right side of the front end cover 1. Side doors 11 are rotatably connected to both the front and rear parts of the box body 2. The side doors 11 are both arc-shaped. The rear end cover 3 is clamped on the right side of the box body 2. Anti-slip pads are provided on the lower sides of both the front and rear parts of the front end cover 1 and the lower sides of both the front and rear parts of the rear end cover 3 to facilitate anti-slip. A horizontal partition board 4 is connected to the inner side of the middle part of the box body 2. A vertical partition board 41 is connected to the left side of the horizontal partition board 4. The vertical partition board 41 is connected to the box body 2. Thirty-five heat exchange tubes 5 are connected to the vertical partition board 41. The heat exchange tubes 5 are all connected to the right part of the horizontal partition board 4. A bolt 6 is clamped between the box body 2 and the front part of the front end cover 1. A bolt 6 is also clamped between the box body 2 and the front part of the rear end cover 3. A dust cleaning mechanism 7 is provided on the horizontal partition board 4 that can conveniently scrape off impurities in the U-shaped area of the heat exchange tube 5.

[0023] As Figure 1 , Figure 3 , Figure 4 and Figure 5 shown, the dust cleaning mechanism 7 includes a trackless cylinder 71, an ash brushing plate 72, a rotary scraping plate 73 and a torsion spring 74. The trackless cylinder 71 is connected to the front side of the horizontal partition board 4. The slider of the trackless cylinder 71 is connected to the ash brushing plate 72. The ash brushing plate 72 is hexagonal. The ash brushing plate 72 is slidably connected to the horizontal partition board 4. The heat exchange tubes 5 all pass through the ash brushing plate 72. The rotary scraping plate 73 is rotatably connected to the right part of the horizontal partition board 4. Torsion springs 74 are connected between the front and rear parts of the rotary scraping plate 73 and the horizontal partition board 4 respectively.

[0024] As Figure 1 ,Figure 5 and Figure 6 As shown in Figure 6 , it further includes a vibration mechanism 8. The vibration mechanism 8 includes a support frame 81, a motor 82, a cam 83 and a sieve plate 84. The front side of the rear end cover 3 is connected with the support frame 81. The lower side of the support frame 81 is connected with the motor 82. The output shaft of the motor 82 is connected with the cam 83. The inner side of the middle part of the rear end cover 3 is connected with the sieve plate 84. The sieve plate 84 is in contact with the rotary scraping plate 73.

[0025] When using this device, first place the box body 2 on the ground and use the anti-slip pads for anti-slip. Then drain the water source into the front end cover 1 and isolate it through the vertical partition plate 41 so that the water flows into the heat exchange tube 5. Then connect the flue gas with the box body 2 so that the flue gas enters the box body 2. The heat of the flue gas is absorbed by the water and discharged through the pipeline under the front end cover 1, and the flue gas is discharged through the pipeline under the box body 2. When it is necessary to clean the impurities on the heat exchange tube 5, the side door 11 can be rotated, the trackless cylinder 71 is started, and the ash brushing plate 72 is driven to move to the right, so that the impurities on the heat exchange tube 5 are scraped off onto the horizontal partition plate 4. When the ash brushing plate 72 continues to move to the right, it pushes the rotary scraping plate 73 to rotate, and the torsion spring 74 deforms, so that the impurities on the U-shaped area of the heat exchange tube 5 are scraped off, thus facilitating the scraping of the impurities on the U-shaped area of the heat exchange tube 5. The operation is simple, and the cleaning efficiency and effect are improved. When the ash brushing plate 72 moves to the left, the torsion spring 74 returns to its original state, driving the rotary scraping plate 73 to rotate, so that some impurities adhere to the sieve plate 84. Then start the motor 82 on the support frame 81 to drive the cam 83 to rotate, so that the cam 83 repeatedly knocks on the sieve plate 84, causing the impurities to fall onto the rear end cover 3, thus being able to knock on the sieve plate 84 to facilitate the cleaning of the impurities. After that, pull out the bolt 6 and then clean the impurities in the rear end cover 3.

[0026] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit the protection scope of the present invention. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present invention can be modified or equivalently replaced without departing from the essence and scope of the technical solutions of the present invention.
