Description

Technical Field

[0001] This utility model relates to the field of filter technology, specifically to an assembled filter housing with heat dissipation function. Background Technology

[0002] In the field of filter technology, the design and performance optimization of filter housings have always been a key research focus. As a crucial component in electronic devices, the stability and reliability of filters are directly affected by the housing design. Especially under prolonged operation or high load conditions, internal components of the filter generate heat; if this heat cannot be dissipated in time, performance degradation or even damage may occur. Therefore, the heat dissipation function of the housing becomes a critical factor that cannot be ignored in the design. Furthermore, the ease of assembly of the filter housing directly affects production efficiency and maintenance costs, especially in scenarios requiring frequent disassembly or replacement of internal components. Traditional housing structures often suffer from complex operations and time-consuming processes.

[0003] Some existing patents have attempted to address the aforementioned problems, solving some heat dissipation and assembly issues through specific designs. However, these technologies still have certain shortcomings. For example, the heat dissipation methods of existing housings may not be efficient enough to meet the heat dissipation requirements of high-power filters; at the same time, some housing structures are complex, leading to cumbersome assembly and disassembly processes, increasing the difficulty of use and maintenance. In addition, existing technologies may also be deficient in dustproof and protective performance, affecting the long-term stability of the filter in harsh environments.

[0004] Based on the above, there is an urgent need for a filter housing design that can balance efficient heat dissipation, convenient assembly, and good protective performance. This new housing not only needs excellent heat dissipation capabilities to ensure the continuous and stable operation of the filter, but also needs to achieve rapid assembly and disassembly through optimized structural design, thereby improving usage efficiency and maintenance convenience. Simultaneously, the housing should fully consider the impact of dust and other external environmental factors to ensure the reliability and durability of the filter in diverse application scenarios. This utility model is an innovative solution proposed to address these needs. Utility Model Content

[0005] This invention addresses the shortcomings of existing filter housings in terms of heat dissipation, dust resistance, and overall structural stability by proposing an assembled filter housing with heat dissipation function. Through optimized internal component layout and structural design, this housing significantly improves heat dissipation performance, enhances dust resistance, and strengthens the overall mechanical strength, thereby meeting the needs of use in complex working environments.

[0006] This utility model provides an assembled filter housing with heat dissipation function, including a base plate, a mounting plate, a protective cover, wiring ports, and a frame. The frame forms a closed space around the housing, within which a cooling fan for airflow guidance and a dust filter for dust prevention are installed. The combined design of the cooling fan and dust filter achieves both efficient heat dissipation and dust prevention. Furthermore, the cooling fan is driven to rotate by a motor, the motor speed of which is precisely calculated to ensure that the generated airflow can evenly cover the key heat-generating areas inside the filter. The installation position of the cooling fan is specially designed, located inside the housing near the heat-generating elements to achieve optimal heat dissipation.

[0007] Furthermore, the dustproof net is housed within the mounting frame, which is connected to the side frame via snap-fit ​​connections for easy disassembly and cleaning. The dustproof net employs a multi-layered mesh structure with precisely calculated mesh dimensions to ensure that external dust cannot enter the housing while allowing airflow, thus enhancing dustproof performance while maintaining heat dissipation. Specifically, a deflector plate is provided on the outer side of the dustproof net. The deflector plate's design angle is optimized to guide external airflow along a specific path into the housing, preventing direct airflow impact on the dustproof net and potential blockage.

[0008] Furthermore, the actuating lever works in conjunction with the sleeve to control the opening and closing of the cooling fan. One end of the actuating lever has a sliding rod that passes through the sleeve and makes smooth contact with it via a curved abutment surface, ensuring minimal friction during operation. The other end of the actuating lever has an operating handle, the shape and size of which are designed for easy manual operation. Furthermore, a return spring is located on one side of the actuating lever. When the actuating lever is released, the return spring uses its elastic restoring force to automatically return the actuating lever to its initial state, thereby improving ease of use.

[0009] Specifically, the pin engages with the socket to lock the position of the lever. One end of the pin has a protruding structure that matches a groove in the socket. When the pin is inserted into the socket, the protruding structure fits tightly against the groove, preventing changes in the cooling fan's state due to external vibration or misoperation, thereby enhancing the device's reliability. Furthermore, the other end of the pin has a pull ring with a calculated diameter to facilitate pulling the pin out with finger force.

[0010] Furthermore, the cooling fan is connected to the frame using a specific method, which utilizes bolts and vibration-damping pads to secure the fan to the frame. The bolt preload is precisely calculated to ensure the stability of the cooling fan during operation, while the vibration-damping pads absorb vibrations generated during operation, reducing noise and extending the fan's lifespan. In addition, the installation position and angle of the cooling fan are optimized to allow airflow to circulate within the casing, thereby further improving heat dissipation efficiency.

[0011] Furthermore, the frame and the housing together form a robust integral structure. The frame and the housing are connected by welding, and the width and depth of the weld are calculated to ensure the mechanical strength of the connection. The housing is made of a high-strength alloy, and its thickness is calculated to withstand external impacts without deformation. In particular, the inner side of the housing is equipped with reinforcing ribs, the distribution and number of which are optimized to improve the overall structure's impact resistance, thereby adapting to various complex working environments.

[0012] Furthermore, the wiring port is rationally designed, featuring a sealing ring on its outer side. The sealing ring is made of a specially selected material that maintains good sealing performance under high temperature and humidity conditions, preventing external contaminants from entering the housing. Inside the wiring port is a conductive plate with a plated surface to reduce contact resistance and improve conductivity. Furthermore, the opening direction of the wiring port is designed to facilitate external wiring access while minimizing the impact of wiring bends on signal transmission.

[0013] Specifically, the protective cover covers the exterior of the housing. The cover is made of a corrosion-resistant composite material, and its thickness has been calculated to resist external physical damage. An insulation layer is provided on the inner side of the cover; the thickness and material of this insulation layer are carefully selected to reduce the impact of external ambient temperature on the interior of the housing. Furthermore, the outer surface of the protective cover undergoes special treatment to provide excellent waterproofing, protecting the internal components from external environmental factors.

[0014] This utility model provides an assembled filter housing with heat dissipation function. Through optimized structural design and component configuration, it achieves efficient heat dissipation, good dustproof performance, and stable assembly characteristics. Specifically, the combined design of the cooling fan and dust filter solves the problems of poor heat dissipation and insufficient dustproof capability of traditional housings; the coordinated use of the toggle lever, sleeve, return spring, and pin improves the convenience of operation and the reliability of the device; the robust connection between the frame and the housing significantly enhances the mechanical strength and impact resistance of the housing; and the design of the wiring port and protective cover further enhances the sealing and protective performance of the housing. In summary, this utility model significantly improves the working stability and service life of the filter, meeting the diverse needs of practical applications. Attached Figure Description

[0023] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0024] This utility model provides an assembled filter housing with heat dissipation function. Its structural design, through the synergistic effect of a base plate, mounting plate, protective cover, wiring ports, frame, and multiple functional components, achieves efficient heat dissipation, excellent dustproof performance, and a robust mechanical structure. The specific embodiments of this utility model are described in detail below with reference to the accompanying drawings.

[0025] like Figure 1As shown, the overall structure consists of a base plate 1, a mounting plate 2, a protective cover 3, wiring ports 4, a frame 5, and a frame 51. The base plate 1 serves as the foundation of the entire housing, supporting the internal core components and providing stable support. The mounting plate 2 is mounted on the upper surface of the base plate 1, and is bolted to the base plate 1 for mounting the filter's key electronic components. The frame 5 forms a closed space around the base plate 1 and mounting plate 2. The inner side of the frame 5 is welded to the frame 51; the weld width and depth have been calculated to ensure the mechanical strength of the connection meets the requirements of use in complex environments. The frame 51 is made of high-strength alloy material, and its thickness has been optimized to withstand external impacts without deformation. Furthermore, reinforcing ribs are provided on the inner side of the frame 51 to further enhance its impact resistance.

[0026] like Figure 2 As shown, a cooling fan 7 is installed inside the housing near the heating element, and the cooling fan 7 is driven to rotate by a motor 6. The motor 6 is fixed to the frame 51 and connected using bolts and shock-absorbing pads. The preload of the bolts is precisely adjusted to ensure the stability of the cooling fan 7 during operation, and the shock-absorbing pads absorb the vibration generated during operation, thereby reducing noise and extending service life. The installation position and angle of the cooling fan 7 are optimized so that the airflow can form a circulating flow inside the housing. When the motor 6 starts, the cooling fan 7 drives the airflow from outside the housing, passes through the heating element, and exits from the other side, thereby achieving effective heat dissipation. It is worth noting that the rotational speed of the cooling fan 7 is calculated to ensure that the generated airflow can evenly cover the heating area and avoid local overheating.

[0027] like Figure 3 As shown, the mounting frame 8 is located on the air intake side of the cooling fan 7, and a dust filter 9 is installed inside. The dust filter 9 adopts a multi-layer mesh structure, and the mesh size has been strictly calculated to effectively block external dust from entering the housing while allowing airflow to maintain the heat dissipation effect. The mounting frame 8 is connected to the frame 5 by a snap-fit, which facilitates disassembly and cleaning. To further optimize the airflow path, a guide plate is designed on the outside of the dust filter 9. The angle of the guide plate is adjusted to guide the external airflow along a specific path into the housing, thereby reducing the risk of blockage caused by the airflow directly impacting the dust filter 9.

[0028] like Figure 4As shown, the toggle lever 11 works in conjunction with the sleeve 10 to control the opening and closing of the cooling fan 7. One end of the toggle lever 11 has a sliding rod 13, which passes through the sleeve 10 and makes smooth contact with it via the abutting curved surface 12. This design reduces friction during operation and improves the flexibility of the toggle lever 11. The other end of the toggle lever 11 has an operating handle, the shape and size of which are optimized for easy manual operation. A return spring 14 is located on one side of the toggle lever 11. When the toggle lever 11 is released, the return spring 14 automatically returns the toggle lever 11 to its initial state through elastic restoring force. Furthermore, a pin 15 works in conjunction with a socket 16 to lock the position of the toggle lever 11. One end of the pin 15 has a protruding structure that matches a groove in the socket 16. When the pin 15 is inserted into the socket 16, the protruding structure fits tightly against the groove, preventing changes in the state of the cooling fan 7 due to external vibration or misoperation. The other end of the pin 15 is provided with a pull ring. The diameter of the pull ring is calculated to make it easy to pull out the pin 15 by applying force with your fingers.

[0029] like Figure 5 As shown, the wiring port 4 is rationally designed, with a sealing ring on its outer side. The sealing ring is made of a high-temperature and moisture-resistant material, maintaining good sealing performance in high-temperature and humid environments and preventing external contaminants from entering the housing. Inside the wiring port 4 is a conductive sheet with a plated surface, reducing contact resistance and improving conductivity. The opening direction of the wiring port 4 is adjusted to facilitate external wiring access and reduce the impact of wiring bends on signal transmission. A protective cover 3 covers the outside of the housing. The protective cover 3 is made of corrosion-resistant composite material, and its thickness is calculated to resist external physical damage. The inner side of the protective cover 3 has a heat insulation layer. The thickness and material of the heat insulation layer are carefully selected to reduce the impact of external ambient temperature on the housing's interior. The outer surface of the protective cover 3 undergoes special treatment, providing excellent waterproof performance and protecting internal components from external environmental factors.

[0030] The working principle of this utility model is as follows: S1 Start the motor 6, which drives the cooling fan 7 to rotate, generating airflow that enters from outside the housing. S2 The airflow first passes through the dustproof net 9, which blocks external dust from entering the housing while allowing air circulation. S3 The airflow enters the housing along the guide plate, covering the heating element and carrying the heat out of the housing. S4 When it is necessary to turn off the cooling fan 7, pull the operating handle of the lever 11. The lever 11 cuts off the power to the motor 6 through the cooperation of the slide rod 13 and the sleeve 10. S5 After releasing the lever 11, the return spring 14 pushes the lever 11 back to its initial state. S6 If it is necessary to lock the state of the cooling fan 7, insert the pin 15 into the socket 16, and lock it by the tight fit between the protruding structure and the groove.

[0031] In practical applications, this filter housing is suitable for environments requiring long-term stable operation, such as communication base stations and industrial equipment. For example, in communication base stations, the filter housing solves the overheating problem caused by poor heat dissipation in traditional housings through its efficient heat dissipation system and reliable dustproof design, while also preventing malfunctions caused by dust accumulation. Furthermore, the housing's robust structure and the multiple protective functions of the shield enable it to maintain normal operation even in harsh environments, significantly improving the overall performance and lifespan of the filter.

[0032] In summary, the heat dissipation-functional assembled filter housing provided by this utility model achieves efficient heat dissipation, good dustproof performance, and stable assembly characteristics through optimized structural design and component configuration. The synergistic effect between the components not only solves the defects existing in the prior art but also provides a more reliable technical solution for practical applications.
