Coolers are widely used in industries such as metallurgy, chemical engineering, energy, transportation, light industry, and food processing. They are commonly used heat exchange devices in these industries. The main purpose of cooler airtightness testing is to detect whether there are any leaks inside the cooler, so as to prevent performance degradation or failure due to leaks during use.
[0003] Existing cooler airtightness testing devices, such as the Chinese utility model patent CN217442784U entitled "A Cooler Airtightness Testing Device," include a testing chamber containing a cooler body. An air inlet is located on the top of the cooler body, and a water inlet is fixedly connected to the surface of the testing chamber, communicating with the interior of the chamber. A limiting ring to prevent rotation of the cooler body is located inside the testing chamber, and a drain valve is fixedly connected to the surface of the testing chamber. This patented solution can only perform airtightness testing on a single cooler of a fixed size, resulting in low testing efficiency and failing to meet the factory's requirements for airtightness testing of multiple batches of coolers of different specifications. Therefore, a cooler airtightness testing device needs to be designed to address these issues. Utility Model Content

[0022] 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.
[0023] Please see Figure 1-5This utility model provides a technical solution: a cooler airtightness testing device, comprising a water tank 1, a servo motor 2, a drive gear 3, a driven gear 4, a side shaft 5, a support plate 6, a mounting frame 7, a reinforcing rib plate 8, a bottom track groove 9, a bottom bolt 10, a bottom nut 11, a partition plate 12, a limiting window 13, a horizontal threaded rod 14, a locking disc 15, a clamping plate 16, a vertical plate 17, and a side bolt 18. The servo motor 2 is fixed to one side of the outer wall of the water tank 1. The drive gear 3 is fixed to the output shaft of the servo motor 2. The top end of the drive gear 3 is connected to the bottom end of the driven gear 4. The driven gear 4 is fixedly installed at one end of the side shaft 5. The side shaft 5 is installed on the top of the side wall of the water tank 1 through a bearing seat. A support plate 6 is fixedly installed at the other end of the side shaft 5. The top of the support plate 6 is connected and fixed to the bottom end of the mounting frame 7. A reinforcing rib plate 8 is fixedly installed between the side of the support plate 6 and the bottom of the mounting frame 7. A bottom track groove 9 is opened on the bottom surface of the mounting frame 7. A bottom bolt 10 is installed through the bottom track groove 9. A bottom nut 11 is installed at the bottom end of the bottom bolt 10. The top of the bottom bolt 10 is connected and fixed to the bottom end of the partition plate 12. The partition plate 12 is installed inside the mounting frame 7. A limit window 13 is opened on the vertical part of the partition plate 12. A horizontal threaded rod 14 is installed through the limit window 13. A locking disc 15 is threaded on the horizontal threaded rod 14. A clamping plate 16 is fixed at the end of the horizontal threaded rod 14.
[0024] In this example, the support plate 6 is symmetrically distributed about the center of the installation frame 7, and the support plate 6 is symmetrically fixed with reinforcing ribs 8 on both sides. The above structural design ensures that the support plate 6 and the reinforcing ribs 8 can be stably connected to the installation frame 7, and provide stable support and positioning for the installation frame 7.
[0025] The bottom bolt 10 is slidably connected to the bottom track groove 9. The bottom bolt 10 is symmetrically distributed about the center of the partition plate 12. The above structural design allows the partition plate 12 to slide horizontally along the bottom track groove 9 with the bottom bolt 10, adapting to coolers of different sizes.
[0026] The partition plates 12 are evenly distributed within the mounting frame 7. The front cross-sectional shape of the partition plates 12 is "T". The above structural design enables the partition plates 12 to divide the cooler and to support the bottom of the cooler to prevent it from falling off after the mounting frame 7 is rotated.
[0027] The vertical sides and bottom of the partition plate 12 are in contact with the inner wall of the mounting frame 7. The length of the top of the partition plate 12 is greater than the inner width of the mounting frame 7. The above structural design ensures that the partition plate 12 can be stably installed in the mounting frame 7.
[0028] The horizontal threaded rod 14 and the limiting window 13 are slidably connected. The horizontal threaded rod 14 is symmetrically distributed about the vertical part of the partition plate 12. The above structural design allows the horizontal threaded rod 14 to slide horizontally along the limiting window 13 with the clamping plate 16 to adjust the working position.
[0029] A locking disc 15 and a clamping plate 16 are symmetrically installed on both sides of the center of the horizontal threaded rod 14. The diameter of the locking disc 15 is more than 1.5 times the diameter of the horizontal threaded rod 14, and the frontal width of the clamping plate 16 is not less than 1 / 3 of the length of the bottom track groove 9. The above structural design allows the locking disc 15 to press the vertical part of the partition plate 12 from both sides, so as to stably fix the relative position of the horizontal threaded rod 14 and the partition plate 12. The clamping plate 16 can separate the cooler and prevent the cooler from colliding.
[0030] Vertical plates 17 are fixedly installed on both sides of the top surface of the water tank 1. Side bolts 18 are horizontally installed through the top of the vertical plates 17. The ends of the side bolts 18 are connected to the side of the installation mesh frame 7. The above structural design can lock the erected installation mesh frame 7, ensuring the stability of the installation mesh frame 7 during the installation and disassembly of the cooler.
[0031] Working principle: When using this device, first adjust according to the size of the multiple coolers to be tested. Figure 2 The spacing between adjacent partitions 12 and Figure 5 The spacing between adjacent clamping plates 16, first adjust... Figure 5 The clamping plate 16, along with the horizontal threaded rod 14, slides horizontally along the limiting window 13 until the space on both sides of the clamping plate 16 is suitable for the width of coolers of different sizes. The symmetrically distributed locking discs 15 press the vertical part of the partition plate 12 on both sides, fixing the position of the horizontal threaded rod 14 and the clamping plate 16.
[0032] Then, place the cooler into the space separated by the appropriate clamping plate 16 between adjacent partition plates 12 or between the partition plate 12 and the inner wall of the installation frame 7. Move the partition plate 12 to slide the installation frame 7 along the bottom track groove 9 until the adjacent partition plate 12 or the partition plate 12 and the inner wall of the installation frame 7 squeeze and position the cooler. With the already fixed clamping plate 16, stabilize and fix multiple coolers. Tighten the bottom nut 11 to press the bottom surface of the installation frame 7 and fix the position of the partition plate 12.
[0033] Water can be injected into water tank 1, rotating side bolt 18 to separate from the side of mounting mesh frame 7, and controlling servo motor 2 to drive drive gear 3 to rotate. Drive gear 3 drives driven gear 4 to rotate 180° via side shaft 5, carrying support plate 6 and mounting mesh frame 7. Mounting mesh frame 7 and the cooler installed inside it are completely submerged in water for airtightness testing. After the test, control servo motor 2 to drive drive gear 3 to continue rotating 180° or rotate 180° in the opposite direction to reset mounting mesh frame 7. Figure 2 As shown, the rotating side bolt 18 is connected to the side of the mounting frame 7. Loosen the bottom nut 11 and locking disc 15, and the cooler can be removed. This is the working principle of the airtightness testing device for the cooler.
[0034] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
