Abstract
Description
Technical Field
[0001] This utility model relates to the field of power supply heat dissipation technology, and in particular to an air filter. Background Technology
[0002] Because data center outdoor units typically do not have filtration systems due to a lack of consideration for air cleanliness and cost control, over extended periods of use, debris such as willow catkins, twigs, plastic bags, and dust can accumulate on the evaporators. This severely reduces heat exchange performance, leading to increased power consumption and indoor temperature, which in turn affects the normal operation of the equipment. Utility Model Content
[0003] The purpose of this invention is to address the shortcomings of existing data center outdoor units, which are not equipped with filtration devices. As a result, during long-term use, debris such as willow catkins, branches, plastic bags, and dust may accumulate on the evaporator, severely reducing heat exchange performance, leading to increased power consumption and indoor temperature in the data center, and affecting the normal operation of the equipment. This invention provides an air filter.
[0004] The technical solution adopted by this utility model to solve its technical problem is: an air filter, installed in the filter slot of the outdoor unit of the computer room air conditioner, including a frame, a filter component disposed in the frame, and a plurality of magnetic suction components and pull-out components disposed on the side of the frame; the frame is provided with mounting slots for installing the magnetic suction components and pull-out components, and a plurality of rolling components are also provided on the frame. By utilizing filter components, it is possible to effectively prevent the accumulation of debris such as willow catkins, twigs, plastic bags, and dust on the evaporator, which would severely reduce heat exchange performance, increase power consumption of the computer room air conditioner, raise the indoor temperature of the computer room, and affect the normal operation of the outdoor unit of the computer room air conditioner. By using magnetic components, multiple air filter frames can be magnetically fixed without the need for fasteners, effectively improving the convenience of connection operations. At the same time, by using pull-out components, the air filter can be easily removed from the outdoor unit of the computer room air conditioner. In addition, by using rolling components, the friction between the air filter and the filter screen of the outdoor unit of the computer room air conditioner can be effectively reduced, thereby further improving the convenience of installation and removal operations of the air filter and the outdoor unit of the computer room air conditioner.
[0005] Furthermore, the filter component comprises several layers of filter screen arranged within the frame. In the embodiment provided by this utility model, the filter screen is a washable black PP filter screen, woven from polypropylene (PP) material, and formed into a 40-mesh grid through an optimized weaving process. This allows for the interception of large debris such as tree branches and plastic bags using multiple layers of coarse mesh while maintaining good ventilation performance, avoiding the sudden increase in wind resistance caused by a single-layer dense structure. Moreover, the black PP material possesses weather resistance (UV resistance, high temperature resistance) and hydrophobicity, dries quickly upon contact with water, and is not prone to dirt adhesion. It can be reused after high-pressure water gun washing, thereby effectively reducing maintenance costs.
[0006] Furthermore, the mounting slots are located on both sides of the frame. By placing the mounting slots on both sides of the frame, the ease of installing the magnetic and pull-out components onto the frame, as well as the ease of use for the user, can be effectively improved.
[0007] Furthermore, the magnetic component is a magnet, and the frames 10 of the multiple air filters are connected by magnetic attraction. When multiple air filters need to be placed side by side in the filter slot of the outdoor unit, the magnets of the multiple air filters attract each other, making the air filters fit tightly together, and they can be reliably connected without the need for fasteners, effectively improving the convenience of disassembly and assembly operations between multiple air filters.
[0008] Furthermore, the magnet is a long-slender cylindrical magnet, and the shape of the mounting groove is adapted to the shape of the long-slender cylindrical magnet. By setting the magnet to a long-slender cylindrical magnet, the stability of the air filter's tight fit with the air filter can be effectively ensured, while the shape of the magnet is adapted to the shape of the frame, and the number of magnets that can be installed on both sides of the frame can be effectively increased, further improving the tightness of the direct fit between multiple air filters. In addition, by setting the shape of the mounting groove to adapt to the shape of the magnet, the stability of the magnet installed in the mounting groove can be effectively improved.
[0009] Furthermore, several of the pull-out components are drawstrings, which can be threaded into and stored within the mounting slot. This allows for the removal of the air filter from the filter tray of the outdoor unit of the air conditioner by pulling the drawstring outwards, effectively improving the ease of user installation and removal. Moreover, when multiple air filters are magnetically attached, the drawstrings can be threaded into and stored within the mounting slot, effectively preventing interference from the magnetic attachment and ensuring a tight bond between the filters.
[0010] Furthermore, the rolling component is a ball bearing, and the top and bottom of the frame are provided with several rolling grooves for mounting the ball bearing. By utilizing the ball bearing, the friction between the air filter and the filter screen of the outdoor unit of the computer room air conditioner can be effectively reduced, thereby further improving the convenience of installation and disassembly operations between the air filter and the outdoor unit of the computer room air conditioner. The rolling grooves can effectively ensure the stability of the ball bearing's rotational connection to the top and bottom of the frame and improve the positioning accuracy of the ball bearing mounted on the frame.
[0011] Furthermore, a reinforcing vertical beam is provided at the center of the frame, and reinforcing diagonal beams are symmetrically arranged on both sides of the reinforcing vertical beam to form a rhomboid diagonal beam. Through the reinforcing vertical beam and the rhomboid diagonal beams formed by the symmetrically arranged reinforcing diagonal beams on both sides of the reinforcing vertical beam, multiple stable triangular reinforcing beam structures are formed within the frame, thereby effectively improving the overall strength of the frame.
[0012] Furthermore, the filter screen and the frame are fixedly connected by locking components. By using bolts, studs, and pins to pass through the frame and lock them into the filter screen, the stability of the filter screen installed in the frame can be effectively improved. In the embodiment provided by this utility model, the locking components are stainless steel rivets, thereby meeting the needs of the air filter for outdoor use.
[0013] Furthermore, the frame is made of aluminum profiles with a thickness of 0.8mm, thereby further improving the overall strength of the frame.
[0014] The beneficial effects of the air filter provided by this utility model are as follows: By utilizing the filter components, it is possible to effectively prevent the accumulation of debris such as willow catkins, branches, plastic bags, and dust on the evaporator, which would severely reduce heat exchange performance, increase the power consumption of the computer room air conditioner, raise the indoor temperature of the computer room, and affect the normal operation of the outdoor unit of the computer room air conditioner; By utilizing the magnetic components, the frames of multiple air filters can be magnetically fixed without the need for fasteners, effectively improving the convenience of connection operations; At the same time, by utilizing the pull-out components, the ease of removing the air filter from the outdoor unit of the computer room air conditioner can be effectively improved; In addition, by utilizing the rolling components, the friction between the air filter and the filter screen groove of the outdoor unit of the computer room air conditioner can be effectively reduced, thereby further improving the convenience of installation and disassembly operations between the air filter and the outdoor unit of the computer room air conditioner.

[0025] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.
[0026] See Figure 1-6The present invention provides an air filter 100, which is installed in the filter slot 200 of the outdoor unit of the computer room air conditioner. The air filter 100 includes a frame 10, a filter component 20 disposed in the frame 10, and a plurality of magnetic suction components 30 and pull-out components 40 disposed on the side of the frame 10. The frame 10 is provided with mounting slots 11 for mounting the magnetic suction components 30 and pull-out components 40, and a plurality of rolling components 50 are also provided on the frame 10. By utilizing the filter component 20, it is possible to effectively prevent the accumulation of debris such as willow catkins, branches, plastic bags, and dust on the evaporator, which would severely reduce heat exchange performance, increase the power consumption of the computer room air conditioner, raise the indoor temperature of the computer room, and affect the normal operation of the outdoor unit of the computer room air conditioner. By utilizing the magnetic component 30, the frames 10 of multiple air filters 100 can be magnetically fixed without the need for fasteners, effectively improving the convenience of connection operations. At the same time, by utilizing the pull-out component 40, the ease of removing the air filter 100 from the outdoor unit of the computer room air conditioner can be effectively improved. In addition, by utilizing the rolling component 50, the friction between the air filter 100 and the filter screen groove 200 of the outdoor unit of the computer room air conditioner can be effectively reduced, thereby further improving the convenience of installation and removal operations between the air filter 100 and the outdoor unit of the computer room air conditioner.
[0027] like Figure 1 As shown, the filter element 20 consists of several layers of filter screen arranged within the frame 10. In the embodiment provided by this utility model, the filter screen is a washable black PP filter screen, woven from polypropylene (PP) material, and formed into a 40-mesh grid through an optimized weaving process. This allows for the interception of large debris such as tree branches and plastic bags using multiple layers of coarse mesh while maintaining good ventilation performance, avoiding a sudden increase in wind resistance caused by a single-layer dense structure. Furthermore, the black PP material is weather-resistant (UV resistant, high-temperature resistant) and hydrophobic, dries quickly when wet and is not prone to dirt adhesion, and can be reused after being washed with a high-pressure water gun, thereby effectively reducing maintenance costs.
[0028] like Figure 1 and Figure 2 The mounting slots 11 are provided on both sides of the frame 10. By providing the mounting slots 11 on both sides of the frame 10, the convenience of installing the magnetic component 30 and the pull-out component 40 on the frame 10 and the convenience of using the magnetic component 30 and the pull-out component 40 by the user can be effectively improved.
[0029] like Figure 1 and Figure 2As shown, the magnetic component 30 is a magnet, and the frames 10 of multiple air filters 100 are connected by magnetic attraction. When multiple air filters 100 need to be placed side by side in the filter slot 200 of the outdoor unit, the magnets of the multiple air filters 100 attract each other, so that the air filters 100 fit tightly against each other, and can be reliably connected without fasteners, effectively improving the convenience of disassembly and assembly operations between multiple air filters 100.
[0030] like Figure 1 and Figure 2 As shown, the magnet is a long-slender cylindrical magnet, and the shape of the mounting groove 11 is adapted to the shape of the long-slender cylindrical magnet. By setting the magnet to a long-slender cylindrical magnet, the stability of the air filter 100 being tightly fitted together can be effectively ensured, while the shape of the magnet is adapted to the shape of the frame 10, and the number of magnets that can be installed on both sides of the frame 10 can be effectively increased, further improving the tightness of the direct fit between multiple air filters 100. In addition, by setting the shape of the mounting groove 11 to be adapted to the shape of the magnet, the stability of the magnet installed in the mounting groove 11 can be effectively improved.
[0031] like Figure 3 and Figure 4 and Figure 5 As shown, several pull-out components 40 are drawstrings, which can be threaded into and stored in the mounting slot 11. These drawstrings allow the air filter 100 to be pulled out of the filter tray 200 of the outdoor unit of the air conditioner in the computer room by pulling outwards, effectively improving the ease of disassembly and assembly for the user. Furthermore, when multiple air filters 100 are magnetically attached, the drawstrings can be threaded into and stored in the mounting slot 11, effectively preventing interference from the drawstrings and ensuring the tightness of the magnetic attachment.
[0032] like Figure 3 As shown, a reinforcing vertical beam 12 is provided at the center of the frame 10, and reinforcing diagonal beams 13 are symmetrically arranged on both sides of the reinforcing vertical beam 12, forming a rhomboid diagonal beam. Through the rhomboid diagonal beam formed by the reinforcing vertical beam 12 and the symmetrically arranged reinforcing diagonal beams 13 on both sides of the reinforcing vertical beam 12, multiple stable triangular reinforcing beam structures are formed within the frame 10, thereby effectively improving the overall strength of the frame 10. Furthermore, the frame provided by this utility model is made of aluminum profile with a thickness of 0.8mm, further enhancing the overall strength of the frame.
[0033] like Figure 3 , Figure 5 and Figure 6As shown, the rolling component 50 is a ball bearing, and the top and bottom of the frame 10 are provided with several rolling grooves 14 for mounting the ball bearing. By using the ball bearing, the friction between the air filter 100 and the filter screen groove 200 of the outdoor unit of the computer room air conditioner can be effectively reduced, thereby further improving the convenience of installation and disassembly operations between the air filter 100 and the outdoor unit of the computer room air conditioner. The rolling grooves 14 can effectively ensure the stability of the ball bearing's rotational connection to the top and bottom of the frame 10 and improve the positioning accuracy of the ball bearing mounted on the frame 10.
[0034] like Figure 1 As shown, the filter screen and the frame 10 are fixedly connected by a locking member 60. By using bolts, studs, and pins, the locking member 60 passes through the frame 10 and locks itself inside the filter screen, the stability of the filter screen installed in the frame 10 can be effectively improved. In the embodiment provided by this utility model, the locking member 60 is a stainless steel rivet, thereby meeting the needs of the air filter 100 for outdoor use.
[0035] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model.
