Description

Technical Field

[0001] The present invention belongs to the technical field of information safety cabinets, and in particular relates to a flow-guiding air cooling system and an information safety cabinet. Background Art

[0002] The main function of the guided air cooling system on the information security cabinet is to ensure that the electronic equipment in the cabinet can be effectively cooled under high temperature or high load working conditions, thereby ensuring the stable operation of the equipment and the integrity of the data. Through forced air cooling, the heat generated in the cabinet is quickly discharged to keep the operating temperature of the equipment within a safe range. Reduce equipment failures and shortened life due to excessive temperature. In a high temperature environment, the performance of electronic components may be affected. The guided air cooling system can ensure that the equipment inside the information security cabinet works in a suitable environment. Through effective heat dissipation, the energy consumption of auxiliary heat dissipation equipment such as air conditioners is reduced.

[0003] The air cooling system includes a fan, an expansion valve, an evaporator, a compressor, a condenser, an air cooling unit and a closed refrigerant loop. In the system cooling process, the indoor return air first passes through the fan and filter for preliminary filtration to remove dust and impurities, and then the air enters the evaporator. Through the coolant in the evaporator, heat is absorbed from the air, which reduces the air temperature. Then the cooled air is blown out from the bottom of the information security cabinet into the information security cabinet through the fan to form cold air, and then circulates again to achieve the cooling effect of the entire space;

[0004] The fan and filter in the current air cooling system are set separately. The air can enter the fan only after being filtered by the filter. Another method is that the filter, that is, the filter net, is directly fixed to the air inlet of the fan by screws. These two installation methods are complicated to install and maintain, and tools are required for disassembly, which increases maintenance costs and time, makes it difficult to replace the filter net, and easily leads to a decline in the performance of the air duct system. The air cooling system design is not compact enough and is not suitable for environments with limited space. The system is not sealed enough and is easily affected by dust, debris and even wind and rain. Summary of the invention

[0005] The present invention aims to solve the technical problems in the prior art that the fan and filter are complicated to install and disassemble and have high maintenance costs.

[0006] To achieve the above object, the present invention provides the following technical solutions:

[0014] Preferably, four U-shaped opening grooves are opened at the four corners of the bottom of the lower body in the circumferential direction, the locking block is located in the U-shaped opening groove, and a waist hole is opened on the locking block. The locking block is screwed and fixed to the lower body by a screw rod passing through the waist hole.

[0015] The design of the U-shaped opening slot and the locking block allows the lower body to be quickly assembled and separated from the wind shield, making maintenance and repair easier.

[0016] Preferably, the centrifugal fan is fixed to the bottom of the mesh plate, and the four corners of the mesh plate are screwed and fixed to the mounting columns with holes by bolts.

[0017] Preferably, ear plates with knob holes are provided at the four corners of the top of the upper body, and the locking knob passes through the knob hole on the ear plate. The locking block on the locking knob is locked and fixed to the bottom of the ear plate by turning the locking knob, and then the cover is locked and fixed to the fan cover and sealed with the fan cover.

[0018] The design of the lugs and locking knob allows the cover to be quickly and securely locked onto the fan guard.

[0019] An information security cabinet comprises a cabinet, a top plate located at the top of the cabinet, and the above-mentioned flow-guiding air cooling system.

The clip is equivalent to a clip protrusion that can penetrate the through hole A and the top plate, and is limited below the top plate after penetrating the top plate. The clip is an elastic clip.

[0022] Compared with the prior art, the technical effects and advantages of the present invention are:

[0023] The guided air cooling system and information security cabinet achieve efficient air flow and filtration through precisely designed hoods, fan hoods and cover components, as well as removable filter baffles and filters. The through hole A on the hood allows the lower half to pass through easily and be locked in place, while the perforated mounting blocks at the four corners of the hood ensure the stable installation of the hood. The filter baffle is slidably inserted into the inner side of the upper half of the fan hood, and the breathable mesh and inclined inserts on it help to correctly guide the airflow and position the filter. The entire system can be quickly assembled and disassembled through quick connectors such as locking knobs and screws, which is convenient for maintenance and repair.

[0024] The flow-guiding air cooling system and information security cabinet improve the maintainability and safety of the system by simplifying the installation and maintenance process. The design of the detachable filter baffle and filter makes cleaning and replacement more convenient without the use of tools, reducing maintenance time and cost. In addition, the compact design of the system and the optimized layout of the filter enable the air cooling system to maintain high ventilation efficiency in a limited space, while reducing performance degradation caused by filter blockage.

[0043] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0044] The following is combined with Figure 1-12 To further explain this application in detail,

[0045] The embodiment of the present application discloses a guide air cooling system, including a return air fan assembly 100, the return air fan assembly 100 is arranged in a closed refrigeration cycle system, and the return air fan assembly 100 includes an air hood 1, a fan hood 2 and a cover 3;

[0046] The hood 1 is connected to a return air duct 101 connected to the evaporator in the refrigeration cycle system; the hood 1 is provided with a through hole A102 for the lower half 201 to pass through, the four corners of the hood 1 are provided with a mounting block 103 with a hole, and the top of the hood 1 is fixed with a plug-in slot 104 for sealingly plugging in with the frame plate 301 at the bottom of the cover 3. The through hole A102 allows the lower half 201 to pass through easily, which is convenient for assembly and installation. The mounting block 103 with a hole provides a firm fixing point, so that the hood 1 can be stably installed in an appropriate position to ensure the stability and sealing of the system.

[0047] The fan cover 2 includes a lower body 201 passing through the fan cover 1 and an upper body 202 limited in the fan cover 1. The cover 3 cooperates with the fan cover 1 to form a wind cavity. A detachable filter baffle 203 is slidably inserted into the inner side of the four sides of the upper body 202. A filter 204 is installed in the filter baffle 203.

[0048] The inner hole size of the upper body 202 increases from bottom to top, and the four inclined surfaces of the upper body 202 are provided with air permeable mesh openings A208, and the inner surfaces of the four inclined surfaces of the upper body 202 are respectively provided with two inclined inserts 209 located on both sides of the air permeable mesh openings A208. The gradual increase in the inner hole size is conducive to air flow and improves air cooling efficiency. The air permeable mesh openings A208 provide additional air flow channels and increase ventilation area, while the inclined inserts 209 help to correctly install and position the filter baffle 203.

[0049] The filter baffle 203 is provided with a ventilation mesh opening B210 corresponding to the ventilation mesh opening A208, the inner side of the filter baffle 203 is provided with a placement groove 211 for placing the filter 204, and both sides of the filter baffle 203 are provided with guide grooves 212 for guiding and inserting the inclined insert strips 209. The ventilation mesh opening B210 corresponds to the ventilation mesh opening A208, ensuring that the filter baffle 203 does not block the airflow. The design of the placement groove 211 and the guide groove 212 makes it easier to install and replace the filter 204, while also ensuring the correct position and stability of the filter.

[0050] A limit frame 213 is provided on the inner side of the bottom end of the upper body 202 to cooperate with the filter baffle 203 for insertion and limiting. The cover 3 covers the upper body 202 and limits the filter baffle 203 from above. The limit frame 213 and the cover 3 limit the insertion depth of the filter baffle 203, ensuring the correct installation position of the filter, avoiding the filter from being installed too deep or too shallow, and improving the safety and reliability of the system.

[0051] The four corners of the bottom of the lower body 201 are provided with locking blocks 205 for locking and positioning the fan cover 2. Four U-shaped opening grooves 214 are provided at the four corners of the bottom of the lower body 201 in the circumferential direction. The locking blocks 205 are located in the U-shaped opening grooves 214, and the locking blocks 205 are provided with waist holes 215. The locking blocks 205 are screwed and fixed to the lower body 201 through screws 216 that pass through the waist holes 215. The design of the U-shaped opening grooves 214 and the locking blocks 205 allows the lower body 201 to be quickly assembled and separated from the fan cover 1, which is convenient for maintenance and overhaul. The waist holes 215 and the screws 216 on the locking blocks 205 provide a firm connection and ensure the stability of the system.

[0052] Four mounting columns 207 with holes for supporting the centrifugal fan 206 are arranged in a circular pattern at equal distances on the inner bottom wall of the lower half 201; the centrifugal fan 206 is fixed to the bottom of the mesh plate 217, and the four corners of the mesh plate 217 are screwed and fixed to the mounting columns 207 with holes by bolts. This design makes the installation and maintenance of the fan more convenient. The bolt fixation at the four corners of the mesh plate 217 provides sufficient stability, ensuring the safety and efficiency of the fan during operation.

[0053] The size of the cover 3 increases from bottom to top, and the cover 3 is also fixed to the upper half 202 of the fan cover 2 by a locking knob 302. Ear plates 219 with knob holes 218 are provided at the four corners of the top of the upper half 202. The locking knob 302 penetrates the knob holes 218 on the ear plates 219. The locking block 303 on the locking knob 302 is locked and fixed to the bottom of the ear plates 219 by twisting the locking knob 302, thereby locking and fixing the cover 3 to the fan cover 2 and sealingly plugging with the fan cover 1. The design of the ear plates 219 and the locking knob 302 allows the cover 3 to be quickly and firmly locked to the fan cover 2, ensuring the sealing and safety of the system. This quick locking design also greatly simplifies maintenance work.

[0054] An information security cabinet comprises a cabinet 200, a top plate 300 located on the top of the cabinet 200, and the above-mentioned flow-guiding air cooling system.

[0055] The lower half 201 on the return air fan assembly 100 passes through the top plate 300 of the box, and after the locking block 205 is pulled outward to be limited at the bottom of the top plate 300, the lower half 201 is locked and positioned on the top plate 300 by the screw 216 passing through the waist hole 215 on the locking block 205, and the air hood 1 is fixed to the top plate 300 by the screw 216 passing through the mounting block 103 with holes on the four corners of the air hood 1.

[0056] The lower half 201 can be firmly positioned on the top plate 300 by the locking block 205 and the screw rod 216, thereby improving the stability of the entire flow-guiding air cooling system. The design of the lower half 201 allows it to easily pass through the top plate 300, thus simplifying the installation process and reducing the installation time.

[0057] The four outer sides of the lower half 201 are also provided with a clamping strip 220 that penetrates the top plate 300 and is limited at the bottom of the top plate 300. The clamping strip 220 is equivalent to a clamping protrusion that can penetrate the through hole A102 and the top plate 300. After penetrating the top plate 300, it is limited below the top plate 300. The clamping strip 220 is an elastic clamping strip 220. The clamping strip 220 can help accurately position the lower half 201 and ensure that it is correctly positioned on the top plate 300, thereby maintaining the balance and effectiveness of the entire air cooling system. During the operation of the air cooling system, components may be displaced due to vibration or other reasons. The clamping strip 220 can prevent such displacement and ensure the long-term stability of the system.

[0058] When assembling the guide air cooling system and information security cabinet, the lower half 201 is passed through the through hole A102 on the fan cover 1 and locked and fixed by the locking block 205. The filter baffle 203 is detachably installed on the inner side of the upper half 202, and the filter baffle 203 and the filter 204 are arranged on all four sides. When the bottom of the cover 3 is sealed with the ground nails of the fan cover 2, the inner top wall of the cover 3 is pressed against the upper part of the upper half 202 and the cover 3 is fixed on the upper half 202 of the fan cover 2 by the locking knob 302.

[0059] When the filter 204 is disassembled for replacement or cleaning, the locking knob 302 is unscrewed, the fan cover 2 is opened, and the filter baffle 203, the filter 204, and the centrifugal fan 206 are exposed, so that the filter baffle 203 and the filter 204 can be disassembled and replaced conveniently, and the centrifugal fan 206 can be inspected and repaired;

[0060] The filter baffle 203 and filter 204 of the system are designed to be detachable, making it more convenient to replace or clean them. Simply unscrew the locking knob 302 to open the fan cover 2, exposing the filter baffle 203 and filter 204, which is convenient for quick maintenance. The detachable design also makes the maintenance of the centrifugal fan 206 more convenient. Once maintenance is required, the fan can be quickly exposed, saving maintenance time.

[0061] Since the filter 204 is easy to clean and replace, it can ensure that the air duct system maintains a good ventilation efficiency for a long time, reduce the system performance degradation caused by the blockage of the filter 204, and the indoor return air first passes through the filter 204 to remove dust and impurities in the air, ensure air cleanliness, and also protect the evaporator from being blocked by dirt. This design can reduce the operational risks during maintenance and overhaul because it does not require the use of tools for complex disassembly. Compared with the traditional screw fixing method, this quick-release design reduces installation time and labor, thereby reducing installation costs. Due to the detachability of the filter baffle 203 and the flexible design of the fan cover 2, the system is more suitable for environments with limited space. The design of the cover 3 gradually increases from bottom to top, and is fixed to the fan cover 2 by a locking knob 302, which can improve the closedness of the system, prevent dust and debris from entering, and also has the function of blocking wind and rain. Since the filter 204 is easy to clean and replace, it can effectively filter dust and other pollutants in the air, thereby reducing the impact on the environment.

[0062] In general, this design improves the maintainability, safety and efficiency of the system, while also reducing installation and maintenance costs. It is suitable for various occasions with high requirements for ventilation and cooling systems.

[0063] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments or to make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
