Abstract
Description
Technical Field
[0001] This utility model relates to the field of power distribution box technology, specifically a modular high-frequency switching power distribution box. Background Technology
[0002] High-frequency switching power supplies are power supplies that operate at high frequencies using MOSFETs or IGBTs. The switching frequency is generally controlled within the range of 50-100kHz to achieve high efficiency and miniaturization. Distribution cabinets are divided into power distribution cabinets, lighting distribution cabinets, and metering cabinets. They are the final-level equipment in the power distribution system. Distribution cabinets are a general term for motor control centers. Distribution cabinets are used in situations where the load is relatively dispersed and there are fewer circuits. Motor control centers are used in situations where the load is concentrated and there are more circuits. They distribute the electrical energy of a certain circuit of the previous level of power distribution equipment to the nearest load. This level of equipment should provide protection, monitoring, and control for the load.
[0003] However, during the use of power distribution boxes, the internal components generate a lot of heat when powered on. Nowadays, the overall heat dissipation efficiency of power distribution boxes is poor. Natural heat dissipation through the vents can easily allow moisture and dust particles in the air to enter the inside of the power distribution box, which can easily corrode and damage each component, reducing its service life. Furthermore, the installation of internal components is complicated, which can easily lead to component confusion and wire tangling, resulting in troublesome and time-consuming maintenance and heat accumulation, further reducing the service life of the components. Utility Model Content
[0004] (a) Technical problems to be solved

It features modular installation and isolation of internal components, facilitating later maintenance while avoiding heat accumulation and wire tangling. It also boasts high overall heat dissipation efficiency and prevents moisture and dust particles from entering the inside of the distribution box, thus reducing its service life. This solves the aforementioned technical problems.
[0006] (II) Technical Solution
[0007] To achieve the above objectives, this utility model provides the following technical solution: a modular high-frequency switching power supply distribution box, comprising a distribution box body, wherein a first isolation plate and a second isolation plate are movably installed on the inner side of the distribution box body, a heat dissipation seat is provided on the left side of the inner side of the distribution box body, a sealing cover is installed on the front side of the distribution box body by bolts, a heat dissipation vent and an observation window are provided on the front side of the sealing cover, a current guide seat is installed on the rear side of the distribution box body by bolts, a through groove is opened on the rear side of the current guide seat, and a support leg is fixedly installed on the bottom side of the distribution box body.
[0008] Preferably, the front side of the distribution box body is provided with a fitting groove, and the rear side inside the fitting groove is provided with a first slot and a threaded hole, and there are four first slots and four threaded holes.
[0009] Through the above technical solution, the fitting groove facilitates the positioning and installation of the sealing cover, while the threaded hole facilitates the use of bolts to fix the sealing cover. Furthermore, the No. 1 slot facilitates the combination and installation of the No. 1 isolation plate and the No. 2 isolation plate.
[0010] Preferably, the top and bottom sides of the first isolation plate are respectively provided with second slots, and the outer sides of the first and second isolation plates are respectively fixedly installed with card plates. The size and shape of the card plates are respectively matched with the second slot and the first slot, and the right side of the second isolation plate is provided with a cable tray.
[0011] Through the above technical solution, during use, the components are installed separately inside the independent space formed between the No. 1 and No. 2 isolation plates and the main body of the distribution box. This allows for modular installation and power line connection and limiting via cable trays, facilitating quick inspection and maintenance later. The modular isolation installation also facilitates maintenance and prevents heat buildup and dissipation, thus reducing heat dissipation efficiency. Furthermore, the No. 2 isolation plate is removable, allowing for convenient isolation installation according to requirements. The system is easy and simple to use.
[0012] Preferably, the heat sink includes a mounting base, heat dissipation copper pipes, and connecting frames. Several sets of equidistantly arranged heat dissipation copper pipes are fixedly installed on the right side of the mounting base, and connecting frames are fixedly installed at both ends of the heat dissipation copper pipes. A total of four heat sinks are provided, which are fixedly installed on the left and right sides of the inside of the distribution box body.
[0013] With the above technical solution, when the components inside the distribution box generate heat during operation, the heat is conducted through the copper heat pipes on the four sets of heat sinks, which helps to improve heat dissipation efficiency and effectively isolates moisture and impurities in the air from entering the inside of the distribution box, thus improving its service life.
[0014] Preferably, the size and shape of the sealing cover match the fitting groove, a fixing frame is fixedly installed on the rear side of the sealing cover, the size and shape of the fixing frame matches the connecting frame, and a filter screen is provided on the inner side of the heat dissipation port, and a through hole is opened at each of the four corners of the front side of the sealing cover.
[0015] The above technical solution allows for easy connection between bolts passing through the through-hole and threaded holes, thereby securing the sealing cover. Simultaneously, the No. 1 filter facilitates airflow and filtration, preventing larger dust particles from entering and clogging the heat dissipation copper pipe.
[0016] Preferably, the flow guide seat has a T-shaped structure, and the size and shape of the front end of the flow guide seat match the connecting frame. A second filter screen is provided on the inner side of the through groove. Mounting lugs are provided on the top and bottom sides of the flow guide seat. A total of four flow guide seats are provided.
[0017] Through the above technical solution, since the front end of the flow guide seat is connected to the connecting frame by a snap-fit, it is conducive to heat dissipation while preventing moisture and impurities in the air from entering the interior of the distribution box. At the same time, the No. 2 filter helps to prevent dust and impurities from entering the interior of the distribution box. The installation of the lugs makes it convenient to use bolts to install the flow guide seat.
[0018] Compared with the prior art, this utility model provides a modular high-frequency switching power supply distribution box, which has the following advantages:
[0019] 1. This utility model installs the components separately in the independent space formed between the No. 1 and No. 2 isolation plates and the main body of the distribution box, thereby achieving modular classification and installation. Power lines can be connected and limited through the cable tray, which facilitates quick inspection and maintenance later. At the same time, the modular isolation installation facilitates later maintenance and avoids heat accumulation and diffusion, which would reduce heat dissipation efficiency. Moreover, the No. 2 isolation plate can be disassembled, which makes it convenient to install isolation according to needs. It is easy and simple to use.
[0020] 2. When the components inside the distribution box generate heat during operation, the heat is conducted through the copper heat pipes on the four sets of heat sinks, which helps to improve heat dissipation efficiency. Subsequently, when air flows between the heat dissipation vents and the through slots, it carries away the heat in the independent space, thus achieving rapid heat dissipation. Moreover, during the heat dissipation process, impurities in the air are filtered by the No. 1 and No. 2 filters, which prevents larger impurities from entering the copper heat dissipation pipes and causing blockage. The air flows through the inside of the copper heat dissipation pipes to carry away heat, which is beneficial for heat dissipation while preventing moisture and impurities in the air from entering the inside of the distribution box, avoiding corrosion and damage to the components, and improving the overall service life.

The advantages are that by installing the components separately within the independent space formed between the first isolation plate 2 and the second isolation plate 3 and the main body of the distribution box 1, modular installation is achieved. The cable tray 301 facilitates power line connection and positioning, allowing for quick inspection and maintenance later. Modular isolation installation also facilitates maintenance while preventing heat buildup and dissipation, thus reducing heat dissipation efficiency. Furthermore, the second isolation plate 3 is removable, allowing for convenient isolation installation according to requirements, making it easy and simple to use.

During operation, heat is generated when the components inside the main body of the distribution box 1 are powered on. Heat is conducted through the heat dissipation copper pipes 402 on the four sets of heat sinks 4, which helps to improve heat dissipation efficiency. Then, when air flows between the heat dissipation port 6 and the through slot 9, it carries away the heat in the independent space, thereby achieving rapid heat dissipation. Moreover, during the heat dissipation process, impurities in the air are filtered by the No. 1 filter 502 and the No. 2 filter 901, which prevents larger impurities from entering the heat dissipation copper pipes 402 and causing blockage. The air flows through the inside of the heat dissipation copper pipes 402 and carries away the heat, which is beneficial for heat dissipation while preventing moisture and impurities in the air from entering the inside of the distribution box body 1, avoiding corrosion and damage to components, and improving the overall service life.
