Description

Technical Field

[0001] This utility model relates to the field of high-frequency switching power supply technology, and in particular to a high-frequency switching power supply cabinet that is easy to maintain. Background Technology

[0002] High-frequency switching power supplies are widely used in telecommunications, power, petroleum, new energy, and other fields. As crucial equipment for ensuring uninterrupted power supply and emergency use, the performance, lifespan, and ease of maintenance of the power supply cabinet itself must be effectively guaranteed. Most current high-frequency switching power supply cabinets address the necessary heat dissipation and lifespan requirements, but for maintenance, they typically only use covers or doors to improve ease of repair. In actual maintenance, because electrical components are fixed by welding, heat dissipation mechanisms are also fixed in the cabinet by welding or tightening bolts, and connecting cables are often messy and need not be stacked, maintenance personnel must inspect and disassemble them one by one for maintenance. The cables can also cause interference during operation, making the work very cumbersome, resulting in low maintenance efficiency and increased labor costs.

[0003] Therefore, considering the aforementioned technical problems, it is necessary to provide a new technical solution. Utility Model Content

[0004] The purpose of this invention is to provide a high-frequency switching power supply cabinet that allows for quick assembly and disassembly of various electrical components and facilitates maintenance.

[0005] To solve the above-mentioned technical problems, this utility model provides a high-frequency switching power supply cabinet that is easy to maintain, and the specific technical solution is as follows:

[0006] A high-frequency switching power supply cabinet that is easy to maintain includes a cabinet body. A heat-conducting plate is provided inside the cabinet body, which divides the interior of the cabinet body into a non-communicating mounting cavity and a heat dissipation cavity. The mounting cavity is used to install electrical components, and a heat dissipation mechanism is installed in the heat dissipation cavity. A mounting base is fixedly provided at the bottom of the mounting cavity, and a mounting plate is detachably locked onto the mounting base. Multiple honeycomb holes are evenly distributed on the mounting plate. The bottom of the electrical component is provided with a fixing post that matches the honeycomb holes, and the electrical component is detachably inserted into the honeycomb holes through the fixing post.

[0007] Preferably, the honeycomb holes are arranged in a regular array, and each electrical component has multiple fixing posts at its bottom. At least one honeycomb hole corresponding to the fixing post of the electrical component has a magnetic seat, and the bottom end of the fixing post has a metal contact that is magnetically connected to the magnetic seat.

[0008] Preferably, the heat dissipation mechanism includes heat sinks and a movable frame. Multiple heat sinks are detachably mounted on the movable frame using fastening bolts. Slide rails are also installed at the upper and lower ends of the heat dissipation cavity, and the movable frame is slidably mounted on the slide rails.

[0009] Preferably, the cabinet has an openable door on one side, the slide rail is perpendicular to the length of the door, and the movable frame can move along the length of the slide rail to extend or retract into the cabinet through the door.

[0010] Preferably, the mounting cavity also has wire passage grooves, which are located on the inner side wall of the cabinet, and there are multiple wire passage grooves, which are arranged horizontally or vertically in a staggered manner.

[0011] Preferably, the depth of the wire trough is greater than the diameter of the connecting wire harness between electrical components, and a limiting part is provided at the corner of the staggered wire trough. The top surface of the limiting part is on the same plane as the top surface of the wire trough, and a gap is left between the bottom surface of the limiting part and the bottom surface of the wire trough to allow the connecting wire harness to pass through, so as to form an inverted L-shaped cross section and limit the connecting wire harness.

[0012] Preferably, the cabinet is provided with an exhaust fan that communicates with the heat dissipation cavity on the outer side near the heat dissipation cavity, and air inlets are provided on the four side walls of the heat dissipation cavity.

[0014] This utility model provides an easy-to-maintain high-frequency switching power supply cabinet. The cabinet interior is divided into spaces by a heat-conducting plate, and electrical components are quickly plugged in and installed using honeycomb holes and magnetic bases. Combined with a drawer-type pull-out heat dissipation mechanism, the speed of replacing each module during maintenance is greatly improved, which greatly improves maintenance efficiency. Moreover, when only the heat dissipation mechanism is maintained or replaced, there is no need to disconnect the power, which indirectly improves the working efficiency of the power supply cabinet.

Detailed Implementation

[0019] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0020] Example

[0021] Please see Figure 1 A high-frequency switching power supply cabinet for easy maintenance includes a cabinet body 1. A heat-conducting plate 2 is installed inside the cabinet, dividing the interior into non-communicating mounting cavities 11 and heat dissipation cavities 12. The mounting cavities are used to install electrical components, and the heat dissipation cavities contain heat dissipation mechanisms 3. A mounting base 4 is fixedly installed at the bottom of the mounting cavity 11, and a mounting plate 41 is detachably locked onto the mounting base. Multiple honeycomb holes 42 are evenly distributed on the mounting plate. The electrical components have fixing posts at their bottom that are adapted to the honeycomb holes, allowing the electrical components to be detachably inserted into the honeycomb holes via the fixing posts. The heat-conducting plate is made of thermally conductive silicone, and multiple deformable silicone thermally conductive sheets extending towards the electrical components can also be inserted into the heat-conducting plate. The specific arrangement of the thermally conductive sheets can be adjusted by bending according to the actual model, size, and position of the electrical components.

[0022] The honeycomb holes 42 are arranged in a regular array. Each electrical component has multiple fixing posts at its bottom. At least one honeycomb hole corresponding to a fixing post of an electrical component has a magnetic base 43. The bottom end of the fixing post has a metal contact that is magnetically connected to the magnetic base. In actual production, the position of each electrical component can be preset, and different colors can be used to define the area on the mounting plate. During installation and disassembly, it is only necessary to roughly align the electrical component with the defined area, and the fixing post will attract the honeycomb hole with the magnetic base, realizing quick insertion and removal of each module.

[0023] The heat dissipation mechanism 3 includes heat sinks 31 and a movable frame 32. Multiple heat sinks are detachably mounted on the movable frame using fastening bolts. Slide rails 33 are installed at both the upper and lower ends of the heat dissipation cavity 12, and the movable frame is slidably mounted on the slide rails. Since heat dissipation plates alone have low thermal conductivity, heat sinks are inserted into the heat dissipation cavity. The heat sinks, in conjunction with an exhaust fan, form a rapidly cooling heat dissipation cavity, thereby improving heat transfer efficiency.

[0024] The cabinet 1 has an openable cabinet door on one side. The length direction of the slide rail 33 is perpendicular to the cabinet door. The movable frame can move along the length direction of the slide rail to extend or retract into the cabinet through the cabinet door.

[0025] The mounting cavity 11 is also provided with a wire channel 13, which is located on the inner side wall of the cabinet. There are multiple wire channels, and each wire channel is arranged horizontally or vertically in a staggered manner.

[0026] The depth of the wire passage 13 is greater than the diameter of the connecting wire harness between electrical components. A limiting part 14 is provided at the corner of the staggered wire passage. The top surface of the limiting part is on the same plane as the top surface of the wire passage. A gap is left between the bottom surface of the limiting part and the bottom surface of the wire passage to allow the connecting wire harness to pass through, so as to form an inverted L-shaped cross section and limit the connecting wire harness.

[0027] The cabinet 1 is also provided with an exhaust fan 5 connected to the heat dissipation cavity 12 on the outer side, and air inlets are provided on the four side walls of the heat dissipation cavity.

[0028] The beneficial effects of this utility model are: by dividing the space inside the cabinet through the heat-conducting plate, and by using honeycomb holes and magnetic bases to quickly plug and unplug electrical components, combined with the drawer-type pull-out heat dissipation mechanism, the speed of replacing each module during maintenance is greatly improved, which greatly improves maintenance efficiency. Moreover, when only the heat dissipation mechanism is maintained or replaced, there is no need to disconnect the power, which indirectly improves the working efficiency of the power cabinet.

[0029] Although embodiments of the present invention have been shown and described above, it is understood that the above embodiments are exemplary and should not be construed as limiting the present invention. Those skilled in the art can make changes, modifications and variations to the above embodiments within the scope of the present invention.
