Description

Technical Field

[0001] This utility model relates to the field of computer room cooling and heat exchange technology, and in particular to an indoor cooling and heat exchange device. Background Technology

[0002] The basic principle of indoor refrigeration and heat exchange devices is to transfer heat through phase change or heat transfer to achieve refrigeration. Air conditioning relies on a refrigeration cycle to achieve this process. Taking vapor compression refrigeration as an example, the compressor compresses the refrigerant into a high-temperature, high-pressure gas, which dissipates heat through the condenser and becomes liquid. After being throttled and depressurized by the expansion valve, it absorbs heat and vaporizes in the evaporator. The evaporator absorbs heat from the room, thus cooling the room. This process involves heat exchange and is a typical application of the refrigeration and heat exchange principle. Therefore, air conditioning is a type of refrigeration and heat exchange equipment. In computer rooms, precision air conditioners need to be installed to reduce the temperature inside the computer room.

[0003] The existing publicly available technologies are not convenient for repairing precision air conditioners;

[0004] The existing patent (publication number: CN217423593U) describes a rack-mounted precision air conditioner. By operating the movable rotating base, the maintenance door can be easily opened to inspect the interior of the precision air conditioner body. The operation is convenient and helps to avoid the situation of insufficient maintenance space at the rear of the precision air conditioner body.

[0005] To address the aforementioned issues, existing patents have provided solutions. However, in most existing precision air conditioners used for cooling and heat exchange inside computer rooms, the ventilation mesh on top is integrated with the outer casing, making it inconvenient to disassemble. After prolonged use, it is difficult to clean the surface of the ventilation mesh when dust accumulates. When cleaning directly, the dust can easily fall into the air outlet of the precision air conditioner, affecting its operation.

[0006] Therefore, an indoor cooling and heat exchange device is proposed. Utility Model Content

Detailed Implementation

[0030] 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.

[0031] Please see Figure 1-9 The present invention provides the following technical solution:

[0032] An indoor cooling and heat exchange device includes a precision air conditioner body 1, a control panel 3 and an inspection door 4. A ventilation mechanism 2 is provided on the front side of the precision air conditioner body 1, and a cleaning mechanism 8 is provided on the front side of the ventilation mechanism 2. A sliding rod 6 is fixedly connected to the left side of the precision air conditioner body 1, and elastic clips 18 are fixedly connected to both sides of the front side of the precision air conditioner body 1.

[0033] The ventilation mechanism 2 includes a fixed frame 201, two limiting posts 202, two pull rings 203 and two sliding grooves 204. The surface of the fixed frame 201 is in active contact with the surface of the precision air conditioner body 1. The rear side of the limiting post 202 is fixedly connected to the front side of the fixed frame 201. The pull rings 203 are fixedly connected to the surface of the limiting post 202. The sliding grooves 204 are opened inside the fixed frame 201. The limiting post 202 is movably engaged inside the elastic clip 18.

[0034] In this embodiment: the limiting post 202 is connected to the fixed frame 201 and can be engaged with the elastic clip 18. During installation, the fixed frame 201 is brought close to the machine body, and the limiting post 202 is pressed to engage with the elastic clip 18, thus installing the fixed frame 201 and the ventilation mesh 7. During disassembly, the limiting post 202 can be pulled out by pulling the pull ring 203. The top and bottom of the pull block 804 are fixedly connected with anti-slip strips 12. Holding the pull block 804 can drive the fixed plate 802, the slider 801 and the brush bristles 803 to move in the slide groove 204. At this time, the brush bristles 803 can quickly brush away the dust attached to the surface of the ventilation mesh 7. When the brush bristles 803 are dirty, the screw 9 is removed and the insert block 11 is pulled out to separate the limiting post 201. The position block 10 and slider 801 can be removed, and the fixing plate 802 and brush bristles 803 can be cleaned. When reinstalling, insert the insertion block 11 and tighten the screw 9 to easily reuse the brush bristles 803. When the brush bristles 803 are not needed, they can be moved to the bottom front of the fixing frame 201. This solves the problem that most existing precision air conditioners for cooling and heat exchange inside computer rooms have their top ventilation mesh integrated with the outer shell, making it inconvenient to disassemble. After long-term use of the precision air conditioner, it is inconvenient to clean the surface of the ventilation mesh when dust accumulates. Direct cleaning can cause dust to fall into the air outlet of the precision air conditioner, affecting its operation.

[0035] Specifically, such as Figure 5 As shown, the cleaning mechanism 8 includes two sliders 801, a fixed plate 802, several bristles 803, and a pull block 804. The front side of the slider 801 is fixedly connected to the rear side of the fixed plate 802, the front side of the bristles 803 is fixedly connected to the rear side of the fixed plate 802, the rear side of the pull block 804 is fixedly connected to the front side of the fixed plate 802, and the slider 801 is slidably connected inside the slide groove 204.

[0036] Specifically, such as Figure 3 and Figure 5 As shown, a ventilation mesh 7 is fixedly connected to the inner wall of the fixed frame 201. The rear side of the brush bristles 803 contacts the front side of the ventilation mesh 7. Anti-slip strips 12 are fixedly connected to the top and bottom of the pull block 804. There are several anti-slip strips 12, which are evenly distributed on the top and bottom of the pull block 804.

[0037] Specifically, such as Figure 5 and Figure 6 As shown, a limit block 10 is provided on the rear side of the slider 801. Insert blocks 11 are fixedly connected to the top and bottom of the front side of the limit block 10. Insert slots 13 are provided on the top and bottom of the rear side of the slider 801. Insert blocks 11 are movably inserted into the inside of the insert slots 13.

[0038] Specifically, such as Figure 5 and Figure 6As shown, a screw 9 is provided on the rear side of the limiting block 10. The front side of the screw 9 passes through the limiting block 10 and is connected to the internal thread of the slider 801. The front side of the limiting block 10 is in movable contact with the rear side of the fixing frame 201.

[0039] In this embodiment: by sliding the slider 801 inside the groove 204, the hand-held pull block 804 can be easily moved to move the fixing plate 802 and the brush bristles 803, so that the brush bristles 803 can brush away the dust attached to the surface of the ventilation mesh 7. The anti-slip strip 12 makes the grip of the pull block 804 more stable. By inserting the insert block 11 into the insert 13, the limit block 10 can be prevented from rotating when the screw 9 is tightened. By removing the screw 9, the limit block 10 can be separated from the slider 801, so that the fixing plate 802 and the brush bristles 803 can be easily disassembled, and the brush bristles 803 can be cleaned separately.

[0040] Specifically, such as Figure 1 and Figure 7 As shown, a storage mechanism 5 is provided on the left side of the slide bar 6. The storage mechanism 5 includes a storage box 501, a magnetic block 502 and a sliding card 503. The surface of the sliding card 503 is fixedly connected to the surface of the storage box 501, the magnetic block 502 is fixedly connected to the inner wall of the storage box 501, and the sliding card 503 is slidably connected to the surface of the slide bar 6.

[0041] Specifically, such as Figure 8 As shown, a fixing block 15 is fixedly connected to the bottom of the storage box 501, and a sliding column 19 is slidably connected inside the fixing block 15.

[0042] Specifically, such as Figure 1 and Figure 8 As shown, a pressure plate 17 is fixedly connected to the right side of the sliding column 19, and a rubber pad 16 is fixedly connected to the right side of the pressure plate 17. A spring 14 is movably sleeved on the surface of the sliding column 19. The left side of the spring 14 contacts the surface of the fixed block 15, the right side of the spring 14 contacts the surface of the pressure plate 17, and the surface of the rubber pad 16 is in close contact with the surface of the precision air conditioner body 1.

[0043] In this embodiment: the storage box 501 slides along the slide bar 6 via the sliding card 503, allowing tools to be retrieved and placed at different heights. The magnetic block 502 can attract small iron parts to prevent loss. When the position of the storage box 501 needs to be adjusted, the slide column 19 is pulled to separate the rubber pad 16 from the body, the spring 14 is compressed, and the storage box 501 can be moved. When the slide column 19 is released, the spring 14 rebounds, and the rubber pad 16 contacts the body, using friction to limit the storage box 501 to the required height, making it convenient to open the maintenance door 4 to retrieve tools when inspecting the precision air conditioner body 1.

[0044] Working principle: The limiting post 202 is fixedly connected to the front of the fixed frame 201 via its rear side, and the limiting post 202 can be movably engaged inside the elastic clip 18. When it is necessary to install the fixed frame 201 and the ventilation screen 7, bring the fixed frame 201 close to the precision air conditioner body 1, align the limiting post 202 with the elastic clip 18, and press the fixed frame 201 firmly. The limiting post 202 will then engage with the elastic clip 18, achieving quick installation of the fixed frame 201 and the ventilation screen 7. For disassembly, pull the pull ring 203 outward to overcome the elastic force of the elastic clip 18 and pull the limiting post 202 out of the elastic clip 18. The fixed frame 201 and the ventilation screen 7 can then be removed as a whole. When dust adheres to the surface of the ventilation screen 7 and needs to be cleaned, the operator can use the pull ring 203 to remove it. Block 804, with its anti-slip strip 12, increases friction, facilitating the application of force. Pulling block 804 causes the fixed plate 802, along with the slider 801 and brush bristles 803 connected to it, to move within the slide groove 204. During this movement, the brush bristles 803 contact the surface of the ventilation mesh 7, quickly removing dust. This solves the problem that in most existing precision air conditioners used for cooling and heat exchange in computer rooms, the top ventilation mesh is integrated with the outer casing, making disassembly inconvenient. Furthermore, after prolonged use, cleaning the ventilation mesh surface becomes difficult, as dust can easily fall into the air outlet, affecting the air conditioner's operation. When the surface of the brush bristles 803 is covered with a lot of dust, affecting the brushing effect, the screw 9 can be removed so that its front side is unscrewed from the inside of the slider 801. The insert 11 can be pulled out from the socket 13, separating the limit block 10 from the slider 801. The fixing plate 802 and the brush bristles 803 can then be removed for separate cleaning. After cleaning, they can be reinstalled by inserting the insert 11 into the socket 13 and tightening the screw 9. This will prevent the limit block 10 from rotating, allowing it to connect with the slider 801 and restoring the cleaning function. The storage box 501 is used to store tools during maintenance. The storage box 501 is slidably connected to the surface of the slide rod 6 via the sliding clip 503 and can slide up and down along the slide rod 6 to accommodate different heights. For the need to access tools, the magnetic block 502 on the inner wall of the storage box 501 can attract small iron parts such as screws 9, making them easy to access and store, and preventing parts from being lost. When the position of the storage box 501 needs to be adjusted, the slide column 19 is pulled, which moves the pressure plate 17 and the rubber pad 16 to the left. The spring 14 is compressed, and at this time the rubber pad 16 separates from the surface of the precision air conditioner body 1, and the friction disappears, so the storage box 501 can be easily moved to the desired position. After releasing the slide column 19, the spring 14 rebounds, pushing the pressure plate 17 and the rubber pad 16 to the left, so that the rubber pad 16 is in close contact with the surface of the precision air conditioner body 1, increasing the friction and thus limiting the storage box 501 to the required height, making it convenient for maintenance personnel to access tools at any time.

[0045] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
