Description

Technical Field

[0001] The utility model relates to the technical field of high-power amplifiers, and particularly relates to a waterproof high-power amplifier for outdoor use. Background Technique

[0002] With the continuous development of outdoor communication, broadcasting, monitoring and other application fields, the demand for high-power amplifier equipment is increasing day by day. These devices usually need to operate stably outdoors for a long time. However, the outdoor environment is complex and changeable, especially affected by factors such as humidity, rain, dust, and sand. Traditional amplifier devices have many deficiencies in waterproofing, dustproofing, and heat dissipation, and it is difficult to meet the requirements of actual applications.

[0003] At present, common outdoor amplifiers on the market mostly use metal or plastic casings for protection. However, due to unreasonable structural design, it is easy for water vapor to penetrate, affecting the normal operation of electronic components. At the same time, the heat dissipation problem is also an important factor affecting the performance of the device. Traditional amplifiers mostly rely on passive heat dissipation methods, with low heat dissipation efficiency, and it is difficult to cope with the heat accumulation generated by high-power amplifiers, resulting in overheating or even damage of the device and shortening its service life.

[0004] In addition, maintenance and repair are also important considerations for outdoor amplifiers. The module design of most devices is complex, difficult to disassemble, and the repair efficiency is low, increasing the maintenance cost and work difficulty. Therefore, how to design an outdoor high-power amplifier with excellent waterproof, dustproof, and heat dissipation performance and easy to maintain has become an important direction for current technological development.

[0005] Therefore, the present solution specifically proposes a waterproof high-power amplifier for outdoor use to solve the above problems. Content of the Utility Model

[0007] To achieve the above object, the technical solution of the utility model is realized as follows: A waterproof high-power amplifier for outdoor use includes an outer box body and an amplifier module. The front side of the outer box body is closed by a front side end cover provided. A heat dissipation fan is installed at the center of the top of the outer box body. Heat dissipation holes are provided on both sides of the center of the top of the outer box body. A mountain-shaped amplifier fixing frame is installed inside the outer box body. The whole amplifier fixing frame is slidably clamped front and back inside the outer box body. Two amplifier modules are correspondingly installed on the left and right sides of the amplifier fixing frame. The front side end face of the amplifier fixing frame is fixedly connected to the inner end face of the front side end cover. A rain shelter is provided on the top of the outer box body.

[0008] Preferably, the amplifier fixing bracket specifically includes the following structures:

[0009] A U-shaped fixing bracket that slides back and forth and is clamped inside the outer box body;

[0010] A number of U-shaped heat dissipation fins evenly distributed on the top surface of the U-shaped fixing bracket;

[0012] A central separating component distributed at the center position on the top of the U-shaped mounting plate, and two amplifier modules are installed on the top of the U-shaped mounting plate and are correspondingly distributed on the left and right sides of the central separating component.

[0013] Preferably, the central separating component specifically includes the following structures:

[0014] Partition plates installed on the left and right sides of the center position on the top of the U-shaped mounting plate;

[0015] A number of central heat dissipation fins evenly distributed between the partition plates on both sides.

[0016] Preferably, separating strips are provided on both the left and right sides of the center of the inner top of the outer box body, and the bottoms of the separating strips on both sides are respectively slidably attached to the top surfaces of the amplifier modules on both sides, so as to form a mountain-shaped heat dissipation diversion channel inside the outer box body.

[0017] Preferably, longitudinal guide rails are provided at the center and on both sides of the inner bottom of the outer box body, and a leading sliding mechanism for cooperating with the amplifier fixing bracket to slide out of the inner part of the outer box body is provided inside each guide rail.

[0018] Preferably, the leading sliding mechanism specifically includes the following structures:

[0019] A guide post installed inside the guide rail;

[0020] A guide sleeve slidably sleeved on the guide post;

[0021] A magnetic attraction block distributed at one end inside the guide rail and magnetically attracted to the guide sleeve.

[0022] Preferably, a pull handle for driving the amplifier fixing bracket to be pulled out is installed at the center of the outer end face of the front end cover.

[0023] Preferably, buckles for positioning at the front end of the outer box body are installed at the left and right side edges of the front end cover.

[0024] The beneficial effects of the present utility model are embodied in:

[0025] Excellent waterproof performance: By using an outer box made of corrosion-resistant materials in combination with a sealed front end cover and a quick-locking mechanism, as well as a rain shelter on the top, this amplifier can effectively prevent water intrusion, thus adapting to various humid or rainy outdoor environments. The design of the rain shelter not only protects the device from direct sunlight but also prevents rain from directly contacting the electronic components, thereby enhancing the durability and reliability of the entire device.

[0026] Efficient heat dissipation performance: The cooling fan at the center of the device top works in conjunction with the side heat dissipation holes to effectively manage the internal heat. Through innovative air flow guiding technologies (such as the design of U-shaped heat dissipation fins and air guiding perforations), the air flow inside the amplifier is strengthened. This design not only accelerates the heat discharge but also ensures that the external cold air can evenly flow through the amplifier module, greatly improving the heat dissipation efficiency.

[0027] Convenience in maintenance and operation: The slide rail system and the extraction sliding mechanism inside the U-shaped fixing bracket allow for quick and easy extraction and replacement of the amplifier module, greatly simplifying the maintenance and troubleshooting processes. In addition, the design of the front end cover takes into account an easy-to-operate pull handle, making subsequent maintenance operations even more convenient.

[0028] This design concept ensures that while keeping the internal components dry and safe, the amplifier can also effectively dissipate heat, solving two common challenges of outdoor electronic devices. This not only extends the service life of the device but also ensures performance stability under various climatic conditions. Through these design optimizations, this amplifier is not only suitable for regular outdoor activities, demonstrating extremely high applicability and reliability. Description of the Drawings

[0048] Please refer to the attached drawings of the specification Figures 1-7 The present utility model provides a waterproof high-power amplifier for outdoor use:

[0049] Outer box structure and waterproofness:

[0050] The outer box 1 is made of corrosion-resistant materials to resist the harsh outdoor environment. The front end cover 8 adopts a sealing strip and a quick-locking mechanism to ensure the sealing effect and prevent water and moisture from entering.

[0051] A rain shelter 2 is provided at the top of the outer box 2 to further enhance the waterproof ability and protect the amplifier module from direct sunlight.

[0052] Heat dissipation system:

[0053] A cooling fan 3 is installed at the center of the top of the outer box 1 to promote the flow of hot air and improve the heat dissipation efficiency. Cooling holes 4 are provided on both sides of the cooling fan 3 to help the cooling fan 3 discharge the hot air outside the outer box 1 and ensure the heat dissipation performance.

[0054] Amplifier fixing bracket and module installation:

[0055] The amplifier fixing bracket 6 is designed in a mountain shape to facilitate air flow. At the same time, it is combined with the partition strips 9 provided on the left and right sides of the inner top of the outer box 1 to form an effective heat dissipation diversion channel

[0056] The amplifier fixing bracket 6 is a U-shaped fixing bracket 61 that can slide back and forth inside the outer box, facilitating installation and maintenance.

[0057] U-shaped heat dissipation fins 62 are installed on the top of the fixing bracket to further enhance the heat dissipation effect.

[0058] The amplifier module 5 is installed on the top of the U-shaped mounting plate 63 and is stably positioned through the central partition assembly 64. A number of air guiding perforations 631 provided on the U-shaped mounting plate 63 facilitate the guiding of internal air flow;

[0059] A slide rail system is provided inside the U-shaped fixing bracket 61, simplifying the installation and removal of the amplifier module 5 and allowing users to perform quick maintenance and replacement.

[0060] The heat dissipation fins 62 are made of high thermal conductivity materials such as aluminum or copper to maximize the heat conduction efficiency. These fins accelerate the dissipation of heat by increasing the heat dissipation surface area.

[0061] Module spacing and heat dissipation details:

[0062] The central partition assembly 64 includes a partition plate 641 and a central heat dissipation fin 642, effectively isolating the two amplifier modules 5 on the left and right while enhancing heat dissipation;

[0063] The structure between the partition plate 641 and the central heat dissipation fin 642 is designed to be staggered, which helps to disperse the heat flow and prevent the formation of hot spots, thus maintaining uniform heat dissipation of each part of the amplifier.

[0064] Amplifier Module Extraction and Operation:

[0065] Guide rails 11 are provided at the bottom of the outer box body, and an export sliding mechanism 7 is built-in, including a guide post 71 and a guide sleeve 72.

[0066] The export sliding mechanism is connected to the outer box body through a magnetic attraction block 73 to ensure smooth operation.

[0067] The addition of the magnetic attraction block 73 not only stabilizes the sliding process but also increases the safety during extraction and return, preventing damage caused by accidental impacts.

[0068] End Cover Positioning and Safety:

[0069] A pull handle 82 is installed at the center of the front end cover 8 for extracting or pushing back the amplifier fixing frame 6, simplifying the subsequent maintenance and repair operations of the amplifier module 5.

[0070] The pull handle 82 of the front end cover is designed ergonomically, easy to grasp and operate, and can be easily used even when wearing gloves.

[0071] Specific Heat Dissipation Working Principle

[0072] Start the cooling fan 3 to quickly extract the air at the central position inside the outer box body 1 separated by the two amplifier modules 5 and the partition strip 9 on both sides. At this time, a negative pressure is formed at the central position inside the outer box body, and then the external air enters through the heat dissipation holes 4 on the left and right sides of the top of the outer box body 1, and is then introduced through both sides of a number of U-shaped heat dissipation fins 62, and is aggregated to the central partition component 64 along the U-shaped diversion channel formed between the entire U-shaped fixing frame 61 and the U-shaped mounting plate 63. Finally, it is sent upward between the multiple central heat dissipation fins 642 at the central position of the central partition component 64, and finally discharged at the cooling fan 3, thereby forming an efficient heat dissipation operation for the two amplifier modules 5 placed inside. At the same time, the overall air intake and exhaust structures are distributed on the top of the outer box body 1 and are shielded by the rain shelter 2 provided at the top, effectively improving the waterproof performance of the entire amplifier without reducing its heat dissipation performance.

[0073] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
