Description

Technical Field

[0001] The utility model relates to the technical field of central air-conditioning cooling, in particular to a central air-conditioning cooling device. Background Art

[0002] Central air conditioning is an air conditioning system that is controlled by a main unit through air ducts or hot and cold water pipes connected to multiple terminals to achieve the purpose of indoor air conditioning. Central air conditioning has been a commonly used air conditioning system in public places for many years because of its advantages such as large air processing volume, centralized cold and heat sources, and reliable equipment operation.

[0003] In the prior art, when the central air conditioner is working, it is necessary to cool and dissipate heat for the intermediate air conditioner. The traditional method is a simple natural air circulation method for heat dissipation. This method has a poor heat dissipation and cooling effect. Therefore, some cooling devices for central air conditioners have appeared on the market.

[0004] For example, the national patent number "CN 219868764 U" for "a central air conditioning cooling device" states: "Let the atomizing nozzle spray and cool the central air conditioning body from top to bottom or from bottom to top, so that the water droplets sprayed and atomized on the outer surface of the central air conditioning body absorb the heat generated on the surface and inside of the central air conditioning body under the action of heat exchange";

[0005] Although this method can achieve a good cooling effect, after long-term use, due to the adhesion of water droplets to the air conditioner casing, dust in the outside air is easy to adhere there. When the water droplets dry, these dust will form stains and adhere to the air conditioner casing. Traditional devices do not have the ability to deal with these stains, which leads to poor heat dissipation effect in the attached areas, thereby affecting the cooling of the air conditioner. In view of this, in-depth research was conducted on the above-mentioned problems, which led to the present case. Utility Model Content

DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] Example: See Figure 1-5, a central air conditioning cooling device, comprising a shell 12, a partition 5 is fixed to the inner wall of the shell 12, and a plurality of through holes are vertically penetrated on the outer side of the top of the partition 5, an air conditioning body 1 is installed at the middle position of the top of the partition 5, a plurality of heat dissipation fins 2 are installed on the front and rear ends of the air conditioning body 1, a guide tube 4 is arranged on the outside of the air conditioning body 1, and a driving component for driving the guide tube 4 to move is arranged on one side of the guide tube 4, an installation frame 3 is also arranged on the outside of the air conditioning body 1 above the guide tube 4, and the bottom end of the installation frame 3 is welded to the top of the guide tube 4 through a fixing member, a fixing bar 15 is fixed to the front and rear ends of the interior of the installation frame 3, a plurality of fixing plates 14 are arranged at one end of the fixing bar 15, and an adjusting component for controlling the horizontal direction of the fixing plate 14 is arranged on the end of the fixing plate 14 close to the fixing bar 15, the fixing plates 14 are distributed on both sides of the heat dissipation fins 2 in pairs, and a wiping pad 21 is bonded to the side of the fixing plate 14 close to the heat dissipation fins 2;

[0024] Specifically, Figure 1 , Figure 2 and Figure 3 As shown, when the device is in use, cooling water is transported from the outside to the inside of the guide tube 4. The water fills the inside of the guide tube 4 and is sprayed out from the atomizing nozzles 22 at various positions and sprayed on the heat sink fins 2 for cooling. At the same time, the height of the guide tube 4 is adjusted by the driving component, and the spraying position can be changed to ensure that the heat sink fins 2 are sprayed in all directions.

[0025] Dust-proof ventilation nets 13 are embedded and installed at both the front and rear ends of the housing 12. A collecting hopper 6 is provided below the partition 5, and one end of the collecting hopper 6 extends to the outside of the housing 12 and is provided with a handle. The connection between the collecting hopper 6 and the housing 12 is a sliding connection.

[0026] Specifically, Figure 1 and Figure 5 As shown, the dustproof ventilation net 13 can block some dust while ensuring ventilation. The small water droplets or dust used for spraying will eventually fall due to gravity and enter the interior of the collecting bucket 6 through the partition 5 for temporary storage. The collecting bucket 6 can be pulled out for subsequent processing.

[0027] The driving assembly includes a mounting box 11, which is fixed to one side of the housing 12, and a first servo motor 7 is installed at the top of the mounting box 11, a screw 8 is installed at the output end of the first servo motor 7, and the bottom end of the screw 8 is connected to the bottom end of the inside of the mounting box 11 through a rotating shaft, and a moving bar 10 is sleeved on the outer wall of the screw 8 inside the mounting box 11, and two water inlet pipes 9 are fixed to the inner wall of the moving bar 10, one end of the water inlet pipe 9 extends to the outside of the mounting box 11, and the other end of the water inlet pipe 9 is connected to the inside of the guide pipe 4;

[0028] Two guide posts are fixed between the upper and lower ends of the interior of the installation box 11, and both guide posts penetrate the interior of the moving bar 10, and the moving bar 10 and the guide posts form a sliding fit;

[0029] Reflection receiving plates are installed at both the upper and lower ends of the installation box 11, and infrared ranging sensors are installed at both the upper and lower ends of the moving bar 10;

[0030] Specifically, Figure 1 As shown, starting the first servo motor 7 can drive the screw 8 to rotate, causing the moving bar 10 matched with its thread to move in a vertical direction under the limit guidance of the guide column, thereby driving the water inlet pipe 9 to move, thereby adjusting the position of the guide tube 4. The two water inlet pipes 9 can be connected to an external water source, and the other can be connected to a closed pipe for sealing. Infrared ranging sensors are used on the upper and lower parts of the moving bar 10 to detect the distance between the upper and lower end faces of the moving bar 10 and the top and bottom of the inner wall of the installation box 11, so as to judge the position of the moving bar 10 itself, so that the moving bar 10 can move back when it is in the appropriate position, thereby ensuring the reciprocating movement of the guide tube 4. The control feedback of the sensor here belongs to a relatively mature technology in the prior art and will not be repeated here.

[0031] The adjustment component includes a sliding cavity 16, a plurality of sliding cavities 16 are opened inside the fixing bar 15, and a second servo motor 19 is installed inside one side of the fixing bar 15, a rotating shaft 18 is installed at the output end of the second servo motor 19, one end of the rotating shaft 18 passes through the interior of the plurality of sliding cavities 16, and one end of the rotating shaft 18 is connected to the inner wall of the other side of the fixing bar 15 through a rotating shaft, and an installation sleeve 20 is fixed to the outer wall of the rotating shaft 18 inside the sliding cavity 16, and two sliding blocks 17 are sleeved on the outer wall of the installation sleeve 20, and one end of the sliding block 17 is connected to one end of the fixing plate 14 through a fixing member;

[0032] The two ends of the outer wall of the mounting sleeve 20 are respectively provided with external threads in opposite directions, and the inner wall of the sliding block 17 is respectively provided with internal threads matching therewith, and the connection between the sliding block 17 and the sliding cavity 16 is a sliding connection;

[0033] Specifically, Figure 1 , Figure 3 and Figure 4As shown, the movement of the guide tube 4 can drive the installation frame 3 to move along. Normally, the fixed plates 14 are arranged on both sides of the heat dissipation fins 2, and the wiping pad 21 does not contact the heat dissipation fins 2. The heat dissipation fins 2 normally assist in heat dissipation. When the heat dissipation fins 2 need to be wiped, the second servo motor 19 can be started. The second servo motor 19 can be powered by a battery in the prior art. For ease of observation, it is not drawn here. The second servo motor 19 can drive the rotating shaft 18 to rotate, so that multiple groups of installation sleeves 20 rotate at the same speed, so that the sliding cavities 16 outside each installation sleeve 20 will be close to each other, so that the wiping pad 21 is pressed on the outer surface of the heat dissipation fin 2, and then as the installation frame 3 moves, the wiping pad 21 can wipe the surface of the heat dissipation fin 2.

[0034] It is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. Therefore, the embodiments should be regarded as exemplary and non-restrictive from any point of view, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims be included in the present invention. Any reference numeral in a claim should not be regarded as limiting the claim to which it relates.
