Description

Technical Field

[0001] This utility model relates to the field of heat exchanger technology, specifically a heat exchanger for refrigeration and air conditioning equipment. Background Technology

[0002] A heat exchanger in refrigeration and air conditioning equipment is a device used to exchange heat between fluid media at different temperatures. It plays a crucial role in the refrigeration system, achieving a cooling effect by transferring heat from a high-temperature fluid to a low-temperature fluid. The design and performance of the heat exchanger have a significant impact on the efficiency and performance of the entire refrigeration system. For example, finned heat exchangers, due to their good heat transfer performance and reliable operation, have a wider range of application adaptability and can better align with the overall development trend of heat exchangers.

[0003] Heat exchangers are exposed to air, and dust, dirt and other impurities in the air will enter the heat exchanger with the airflow and gradually deposit on the fin surface and in the channels. Dust has a significant impact on the heat exchange efficiency of finned heat exchangers. Dust will form a thermal resistance layer on the heat exchanger surface, which will hinder the transfer of heat. This will lead to a decrease in the heat exchange efficiency of the heat exchanger, requiring more energy to achieve the same cooling or heating effect. Therefore, a heat exchanger for refrigeration and air conditioning equipment is proposed. Utility Model Content

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] This utility model provides a technical solution: a heat exchanger for refrigeration and air conditioning equipment. Please refer to [link / reference]. Figure 1 , Figure 2 and Figure 3 ,include:

[0026] The outer frame 1 has a coil 2 inside it and heat dissipation fins 3 outside it.

[0027] The first side frame 4 is located on the right side outside the outer frame 1. The first drive motor 5 is installed inside the first side frame 4, and the output end of the first drive motor 5 is equipped with a drive screw 6.

[0028] The second side frame 7 is located on the left side outside the outer frame 1, and a sliding rod 8 is provided inside the second side frame 7;

[0029] The first slider 9 is disposed outside the slider 8. The second slider 16 is installed on the outside of the drive screw 6 through a threaded connection. The second drive motor 13 is installed inside the second slider 16. The output end of the second drive motor 13 is installed with a drive rod 14. An arc-shaped scraper 15 is installed on the outside of the drive rod 14. The drive rod 14 is rotatably connected to the first slider 9.

[0030] Please see Figure 1 A connecting plate 10 is provided on one side of the outer front end of the first slider 9 and the second slider 16, and the connecting plate 10 is connected to the first slider 9 and the second slider 16. The connecting plate 10 is used to connect the first slider 9 and the second slider 16.

[0031] Please see Figure 1 and Figure 2 A comb bar 11 is provided on one side of the rear end of the connecting plate 10, and the comb bar 11 is connected to the connecting plate 10.

[0032] Please see Figure 1 , Figure 2 and Figure 3 The comb 11 is inclined and the gap between the comb 11 is adapted to the gap between the arc-shaped scraper 15. The comb 11 is used to scrape away dust and impurities between the arc-shaped scraper 15.

[0033] Please see Figure 2A vibrator 12 is installed on one side of the lower end of the connecting plate 10, and the vibrator 12 is connected to the connecting plate 10. The vibrator 12 causes the connecting plate 10 to vibrate.

[0034] Please see Figure 1 The coil 2 is connected to the outer frame 1, the heat dissipation fins 3 are connected to the coil 2, and the water inlet pipe and water outlet pipe are provided on the left side of the outer frame 1.

[0035] This solution: The second drive motor 13 is started to rotate the drive rod 14. The arc-shaped scraper 15 on the outside of the drive rod 14 cleans the heat dissipation fins 3, thereby scraping off the dust and debris attached to the outside of the heat dissipation fins 3. The first drive motor 5 controls the drive screw 6 to rotate. The drive screw 6 drives the second slider 16 and the sliding rod 8 to slide the second slider 16. This converts the rotational motion of the drive screw 6 into the linear lifting motion of the first slider 9 and the second slider 16, thereby increasing the cleaning range of the arc-shaped scraper 15. When the arc-shaped scraper 15 rotates to the comb 11, the gap between the comb 11 and the arc-shaped scraper 15 coincides, thereby peeling off the dust and debris attached to the outside of the comb 11 and moving it away from the heat dissipation fins 3. The vibrator 12 is started to make the connecting plate 10 vibrate, which in turn drives the comb 11 to vibrate, improving the scraping effect on the outside of the arc-shaped scraper 15.
