Description

Technical Field

[0001] This utility model relates to the field of variable frequency air cooler technology, specifically a variable frequency air cooler. Background Technology

[0002] An evaporative air cooler is a type of refrigeration equipment that can bring fresh air and lower the temperature in factory workshops, public places, and commercial and entertainment venues. A variable frequency evaporative air cooler is an evaporative air cooler equipped with a frequency converter, which enables stepless speed regulation of the motor and allows the air volume to be adjusted arbitrarily, achieving the effect of energy saving and power saving.

[0003] Please refer to the variable frequency air cooler with announcement number CN210292173U. By installing a mounting plate on top of the air cooler body, the support strength of the top of the air cooler body is increased, thereby allowing the inverter body to be installed on top of the air cooler body. This improves the heat dissipation effect of the inverter body and reduces the difficulty and cost of maintenance. A second shock-absorbing pad is added between the inverter body and the air cooler body to reduce the vibration damage caused by the air cooler body to the inverter body and reduce the maintenance frequency of the inverter body.

[0004] In the aforementioned patents, the inverter body is installed on top of the air cooler body using fasteners such as bolts. This installation is rather cumbersome. When the inverter is damaged by vibration, it is not convenient to quickly disassemble and repair the inverter from the top of the air cooler, thereby reducing the overall performance and quality of the air cooler. This application proposes another technical solution to address this problem. Utility Model Content

[0023] 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.

[0024] Please see Figures 1 to 4 The variable frequency air cooler in this embodiment includes an air cooler body 1, a frequency converter 2, and two mounting columns 3. The air cooler body 1 is provided with a positioning component and an auxiliary shock absorption component.

[0025] Example 1: The positioning component includes miniature electric actuators 4 fixedly installed inside the bottom of two mounting posts 3. Mounting rods 5 are fixedly installed at the output ends of the two miniature electric actuators 4, and connecting frames 6 are fixedly connected to the outer sides of the two mounting rods 5.

[0026] Both mounting posts 3 have extension holes at their tops. The connecting frame 6 extends through the extension holes to the outside of the mounting posts 3. Both sides of the inner walls of the two mounting posts 3 have sliding grooves. The connecting frame 6 is slidably connected to the mounting posts 3 through the sliding grooves. When the micro electric actuator 4 is activated, the connecting frame 6 moves up and down through the mounting rod 5.

[0027] A connecting post 7 is fixedly installed on the top of each of the two connecting frames 6. A rotating rod 8 is rotatably installed inside each of the two connecting posts 7. An installation groove is opened on the top of each of the two connecting posts 7, and a bushing is set inside the installation groove. The rotating rod 8 is rotatably connected to the connecting post 7 through the bushing, which makes it easy for the user to rotate the limiting block 9 flexibly.

[0028] Limiting blocks 9 are fixedly installed on the top of both rotating rods 8, and limiting plates 10 are rotatably installed on the front and back of both limiting blocks 9.

[0029] It should be noted that this variable frequency air cooler, by installing a positioning component, simplifies the disassembly process of the inverter 2 when it is damaged, allowing for faster disassembly and repair of the inverter 2, thereby improving the overall quality and effectiveness of the air cooler.

[0030] Specifically, when the inverter 2 needs to be disassembled, the two limit plates 10 are manually twisted to rotate 180 degrees, releasing the restriction on the front and back of the inverter 2. Then, the two micro electric push rods 4 are activated by the micro controller 15, which moves the two connecting frames 6 upward, causing the connecting column 7 to move upward synchronously, thereby moving the limit block 9 upward and releasing the restriction on the top of the inverter 2. Then, the two limit blocks 9 are manually twisted again to rotate 180 degrees, moving the limit block 9 out of the top of the inverter 2, thereby removing the inverter 2 from the top of the air cooler body 1.

[0031] Example 2: Please refer to Figure 1 Based on Embodiment 1, an auxiliary shock absorption component is also provided on the air cooler body 1. The auxiliary shock absorption component includes a connecting plate 11 fixedly installed on the top of the air cooler body 1. A placement groove is provided on the top of the air cooler body 1, and the connecting plate 11 is fixedly connected to the air cooler body 1 through the placement groove.

[0032] A rubber shock-absorbing pad 12 is provided on the top of the connecting plate 11, and a bolt 13 is threadedly installed on the top of the connecting plate 11. A threaded hole is opened on the top of the connecting plate 11, and a through hole is opened inside the rubber shock-absorbing pad 12. The bolt 13 is threadedly connected to the connecting plate 11 through the through hole and the threaded hole.

[0033] A vertical rod 14 is fixedly installed on the top of the connecting plate 11. An opening is provided inside the rubber shock-absorbing pad 12. The vertical rod 14 extends through the opening to the outside of the rubber shock-absorbing pad 12 and is fixedly connected to the bottom of the mounting column 3. A micro controller 15 is fixedly installed on the bottom of the inner wall of both mounting columns 3. The micro controller 15 is connected to the micro electric actuator 4 by signal, so that the user can start the micro electric actuator 4.

[0034] It should be noted that this variable frequency air cooler has an auxiliary vibration damping component to dampen the frequency converter 2 on the top of the air cooler, reducing the possibility of damage to the frequency converter 2 due to vibration, improving the quality of use of the frequency converter 2, and thus improving the overall quality of use of the variable frequency air cooler.

[0035] Specifically, in this variable frequency air cooler, when installing the inverter 2, the rubber vibration damping pad 12 is attached to the connecting plate 11, and then fixed to the top of the connecting plate 11 with bolts 13. Then the inverter 2 is installed on the rubber vibration damping pad 12. To a certain extent, this can reduce the large vibration generated when the air cooler body 1 is operating, which may cause damage to the inverter 2, improve the quality of use of the inverter 2, and thus improve the effect of the variable frequency air cooler.

[0036] The working principle of the above embodiments is as follows:

[0037] (1) When the inverter 2 needs to be disassembled, manually twist the two limit plates 10 so that the two limit plates 10 rotate 180 degrees and release the limit on the front and back of the inverter 2. Then, through the micro controller 15, start the two micro electric push rods 4 to drive the two connecting frames 6 to move upward, so that the connecting column 7 moves upward synchronously, and then the limit block 9 moves upward, releasing the limit on the top of the inverter 2. Then continue to manually twist the two limit blocks 9 so that the two limit blocks 9 rotate 180 degrees and move the limit block 9 out of the top of the inverter 2, and then move the inverter 2 out from the top of the air cooler body 1.

[0038] (2) When installing the inverter 2, the rubber damping pad 12 is attached to the connecting plate 11 and then fixed to the top of the connecting plate 11 with bolts 13. Then the inverter 2 is installed on the rubber damping pad 12. This can reduce the large vibration generated when the air cooler body 1 is operating, which may cause damage to the inverter 2, improve the quality of the inverter 2, and thus improve the effect of the inverter air cooler.
