Description

Technical Field

[0001] This invention relates to the field of heating, ventilation and air conditioning technology, specifically to a heating, ventilation and air conditioning heat dissipation device. Background Technology

[0002] Heating, ventilation, and air conditioning (HVAC) are air conditioning units that provide heating, ventilation, and air conditioning functions. Because the main functions of HVAC include these three aspects, it is called HVAC.

[0003] In existing technology, by installing a wind-cooled heat dissipation device and then using a clamping and fixing device to install it onto the outdoor unit of the air conditioner, the fan can remove heat from the surface of the outdoor unit after the fan is turned on. The sunshade can effectively block the sun's heat, and the filter can prevent dust from entering the fan. With the clamping and fixing device, after first fitting the U-shaped base onto the outdoor unit and adjusting its position, turning the handwheel can drive the movable bolt to rotate in the fixing nut seat, thereby moving the clamping block at the other end towards the outer surfaces of both sides of the outdoor unit, thus achieving quick installation of the sunshade and the outdoor unit. However, existing technology cannot provide comprehensive heat dissipation for HVAC systems, nor can it adapt to the installation and heat dissipation of HVAC systems of different sizes.

[0028] Specifically, the telescopic adjustment mechanism 6 is used to adjust the distance between the lower mounting ring 2 and the upper mounting ring 4 so that it can adapt to HVAC systems of different heights. The elastic spiral plate 3 limits the movement trajectory of the slider 7. The rotation drive mechanism 11 is used to drive the lower mounting ring 2 to rotate. The feed displacement mechanism 8 is used to adjust the position of the inner cleaning mechanism 9 and the outer cleaning mechanism 10 so that the inner cleaning mechanism 9 cleans the outer surface of the HVAC system and the outer cleaning mechanism 10 cleans the outer dust cover 13. The spray cooling mechanism 12 is used to directly cool the HVAC system.

[0029] Please see Figures 1-2 As shown, the telescopic shaft mechanism 6 includes a telescopic shaft 601 rotatably connected to the lower mounting ring 2. The telescopic shaft 601 is coaxially fixedly connected to a threaded rod 602. The threaded rod 602 passes through the upper mounting ring (4) and is threadedly connected to the upper mounting ring 4. The top of the threaded rod 602 is fixedly connected to a rotating handle 603. The telescopic shaft 601 passes through the slider 7 and is slidably connected to the slider 7. The elastic spiral plate 3 passes through the slider 7 and is slidably connected to the slider 7.

[0030] Please see Figure 2 As shown, the feed displacement mechanism 8 includes a linear motor 801 fixedly mounted on the slider 7 near one end of the telescopic shaft 601. The output shaft of the linear motor 801 is fixedly connected to the feed plate 802. The feed plate 802 is fixedly connected to the feed rod 803. The feed rod 803 passes through the slider 7 and is slidably connected to the slider 7.

[0031] The internal cleaning mechanism 9 includes a first motor 901 fixed to the slider 7 near one end of the spiral plate. The output shaft of the first motor 901 is fixedly connected to a first rotating shaft 902. The first rotating shaft 902 is coaxially fixedly connected to a first gear 903. The first gear 903 meshes with a second gear 904. A rotating sleeve 905 is rotatably connected to one end of the slider 7 near the elastic spiral plate 3. The second gear 904 is fixed to the outside of the rotating sleeve 905. A second rotating shaft 906 is provided inside the rotating sleeve 905. A slot is provided in the axial direction of the second rotating shaft 906. A locking block matching the slot is provided in the axial direction of the rotating sleeve 905. The locking block engages with the slot. A rotating shell 908 is passed through and fixedly connected to the second rotating shaft 906. A rotating plate 909 is rotatably connected to the rotating shell 908. The rotating plate 909 is fixedly connected to the feed rod 803. An internal cleaning plate 907 is fixedly connected to the top end of the second rotating shaft 906.

[0032] Please see Figure 1 , Figure 5As shown, the rotary drive mechanism 11 includes a motor mounting base 1101 fixedly installed on the outside of the bottom ring shell 1. The motor mounting base 1101 is fixedly connected to a third motor 1102. The output shaft of the third motor 1102 is fixedly connected to a third gear 1103. The third gear 1103 meshes with an annular rack 1104. The annular rack 1104 is fixedly installed on the bottom of the lower mounting ring 2.

[0033] Specifically, by rotating the handle 603, the threaded rod 602 is rotated, thereby raising and lowering the upper mounting ring 4. This allows for adjustment of the distance between the lower mounting ring 2 and the upper mounting ring 4, enabling it to adapt to HVAC systems of different heights. Meanwhile, the elastic spiral plate 3 supports the upper mounting ring 4 on one hand and limits the movement trajectory of the slider 7 on the other.

[0034] If the internal cleaning mechanism 9 and the spray cooling mechanism 12 need to rotate, the third motor 1102 is turned on. The rotation of the output shaft of the third motor 1102 will drive the third gear 1103 to rotate. The rotation of the third gear 1103 will drive the ring rack 1104 to rotate, which in turn will drive the lower mounting ring 2 to rotate. The lower mounting ring 2 can drive the slider 7 to rise and fall along the elastic spiral plate 3 through the threaded rod 602, and at the same time drive the spray cooling mechanism 12 to rotate.

[0035] When the linear motor 801 is turned on, it drives the feed plate 802, which in turn drives the feed rod 803 to extend and retract, causing the rotating housing 908 and the rotating plate 909 to extend and retract. This, in turn, drives the second rotating shaft 906 and the inner cleaning plate 907 to extend and retract. At this time, the first motor 901 is turned on, and the rotation of the output shaft of the first motor 901 drives the first rotating shaft 902 to rotate. The rotation of the first rotating shaft 902 drives the first gear 903 to rotate, and the rotation of the first gear 903 drives the second gear 904 to rotate, which in turn drives the rotating sleeve 905 to rotate, thereby driving the locking block to rotate, which in turn drives the second rotating shaft 906 to rotate, causing the inner cleaning plate 907 to rotate, thus achieving efficient cleaning of the HVAC system.

[0036] Please see Figure 1 As shown, the spray cooling mechanism 12 includes a flexible water pipe 1201 fixed between the lower mounting ring 2 and the upper mounting ring 4. The flexible water pipe 1201 is provided with a plurality of spray heads 1202. An embedded water pipe is provided inside the lower mounting ring 2. The embedded water pipe is connected to the flexible water pipe 1201. The embedded water pipe is connected to the water inlet, which is located on the lower mounting ring 2.

[0037] Specifically, by supplying water to the embedded water pipe through the water inlet, cooling water can enter the flexible water pipe 1201, and finally the water can be sprayed out through the spray head 1202 to the surface of the HVAC system to achieve HVAC cooling.

[0038] The lower mounting ring 2 and the upper mounting ring 4 are provided with dust covers 13.

[0039] Specifically, the dust cover 13 reduces the amount of dust entering the HVAC system.

[0040] Example 2, see below. Figures 1-5 In this embodiment of the invention, the external cleaning mechanism 10 includes a second motor 1001 fixed on the feed plate 802, and the output shaft of the second motor 1001 is fixedly connected to the external cleaning plate 1002.

[0041] Specifically, when the second motor 1001 is turned on, the output shaft of the second motor 1001 rotates, which drives the outer cleaning plate 1002 to rotate. When the outer cleaning plate 1002 comes into contact with the dust cover 13, it can remove the dust attached to the dust cover 13.

[0042] The working principle of the entire device is as follows: First, the entire device is placed outside the HVAC unit that needs heat dissipation. Depending on the height of the HVAC unit, rotating the handle 603 drives the threaded rod 602 to rotate, raising or lowering the upper mounting ring 4. This adjusts the distance between the lower mounting ring 2 and the upper mounting ring 4, ensuring the exhaust fan 5 is directly above the HVAC unit, facilitating heat dissipation after the exhaust fan 5 is turned on. When the HVAC unit temperature is high, the spray cooling mechanism 12 is activated to spray water and accelerate cooling. Simultaneously, the rotary drive mechanism 11 is activated, using the third motor to drive the third gear 1103. The rotation of the third gear 1103 drives the ring rack 1104, which in turn drives the lower mounting ring 2. The lower mounting ring 2 then drives the spray cooling mechanism 12 to rotate, achieving a surrounding spray cooling effect on the HVAC unit. Simultaneously, the rotation of the lower mounting ring 2 drives the telescopic shaft mechanism 6 and the slider 7 to rotate. Due to the presence of the elastic spiral plate 3... The trajectory of the slider 7 can be limited, allowing the slider 7 to move up and down along the elastic spiral plate 3. In conjunction with the feeding and positioning mechanism 8, the linear motor 801 is activated, which drives the feeding plate 802. The feeding plate 802 drives the feeding rod 803 to extend and retract, causing the rotating shell 908 and the rotating plate 909 to extend and retract, which in turn drives the second rotating shaft 906 and the inner cleaning plate 907 to extend and retract. At this time, the first motor 901 is activated, and the output shaft of the first motor 901 rotates, which drives the first rotating shaft 902 to rotate. The rotation of the first rotating shaft 902 drives the first gear 903 to rotate, which drives the second gear 904 to rotate, which in turn drives the rotating sleeve 905 to rotate, thereby driving the locking block to rotate, which in turn drives the second rotating shaft 906 to rotate, causing the inner cleaning plate 907 to rotate. This enables the inner cleaning mechanism 9 to clean the dirt and dust on the surface of the HVAC system. Similarly, the outer cleaning mechanism 10 can clean the outer dust cover 13.

[0043] This invention allows for adjustment of the distance between the lower mounting ring 2 and the upper mounting ring 4 via a telescopic shaft mechanism 6, accommodating HVAC installations at different heights. A spray cooling mechanism 12 provides spray cooling for the HVAC system. A feed positioning mechanism 8 adjusts the positions of the inner cleaning mechanism 9 and the outer cleaning mechanism 10. The inner cleaning mechanism 9 performs contact cleaning of the HVAC system, while the outer cleaning mechanism 10 cleans the dust cover 13, preventing clogging. A rotation drive mechanism 11 drives the inner cleaning mechanism 9 and the outer cleaning mechanism 10 to rotate, achieving comprehensive cleaning coverage. Simultaneously, it rotates the spray cooling mechanism 12, ensuring uniform cooling and improving the heat dissipation efficiency of the HVAC system.
