Description

Technical Field

[0001] This utility model relates to the field of high-frequency switching technology, specifically a modular high-frequency switching power supply device. Background Technology

[0002] High-frequency power switches, also known as rectifier switches (SMRs), are high-frequency power supplies that operate through MOSFETs or IGBTs, with the switching frequency typically controlled between 50-100kHz.

[0003] Most electrical energy is produced using alternating current (AC), but in actual power grid applications, there are a large number of loads that require direct current (DC). During the use of electrical energy, a large number of AC / DC conversion devices are needed to convert AC power into DC power required by the DC loads.

[0004] Currently, due to the limited installation space of high-frequency switching circuit boards, wiring errors are prone to occur during wiring. Furthermore, when the internal high-frequency switching circuit boards operate in humid air, they are susceptible to the influence of external air moisture as they need to dissipate heat.

[0005] To address this, a modular high-frequency switching power supply device is proposed. Utility Model Content

[0006] The purpose of this invention is to provide a modular high-frequency switching power supply device that filters and dries water vapor in the gas by setting water vapor filter cotton in the heat dissipation structure, thereby solving the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] A modular high-frequency switching power supply device includes a housing, a gate, a slide rail, and a mounting plate. The slide rail is fixedly disposed inside the housing, and the mounting plate is slidably disposed inside the slide rail. An ammeter, a control panel, and a rotary switch are disposed on the side wall of the housing. A gate is rotatably disposed at one end of the housing. A cover plate is fixedly disposed on the side of the housing opposite to the gate. A heat dissipation assembly is disposed on the cover plate. Threaded holes are provided at the four corners of the cover plate, and the cover plate is fixedly disposed on the housing by screws.

[0009] Preferably, the heat dissipation assembly includes a boss, a protective cover, and a fan. The boss is fixedly mounted on the cover plate, the protective cover is fixedly mounted on the boss, the boss has a cavity inside, and the fan is fixedly mounted inside the boss by screws.

[0010] The boss, cover plate, and protective cover are integrally formed.

[0011] Preferably, one side of the protective cover has an arc-shaped opening, and an arc-shaped plate is detachably installed on the arc-shaped opening. A ring is attached to the arc-shaped plate, and water vapor filter cotton is provided on the ring. The water vapor filter cotton is attached to the ring by hot melt adhesive or adhesive with adhesive properties.

[0012] The protective cover has mounting ears on both sides, and the arc plate also has mounting ears. The arc plate is fixedly installed onto the protective cover by bolts.

[0013] The water vapor filter cotton uses an industrial sponge de-misting filter screen, which can absorb moisture from the air that passes through the water vapor filter, allowing dry air to enter the shell to dissipate heat from the internal circuit boards, electronic components, etc.

[0014] Preferably, there are multiple slide rails and multiple mounting plates. Each mounting plate has multiple vent holes and multiple threaded posts.

[0015] The internal circuit board and circuit modules of the high-frequency switching power supply are also provided with mounting holes, and are fixed to the threaded post by screws. The circuit board, circuit modules and other components are distributed in a modular manner and installed on the corresponding mounting plate.

[0016] The internal circuit boards and circuit modules are installed using threaded posts, creating a gap between the circuit boards and the vents. This allows the cooling air to make better contact with the surface of the circuit boards, resulting in more efficient heat dissipation.

[0017] Preferably, locking lugs are provided on the side wall of the door and the end of the outer casing, and a handle is fixedly installed on the top of the outer casing.

[0018] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0019] 1. Multiple mounting plates are provided, allowing the internal circuit boards and electronic components of the high-frequency switching power supply to be categorized by function or size and mounted onto multiple mounting plates. The mounting plates are pulled out to the outside of the housing, and the circuit boards and electronic components are mounted onto the corresponding mounting plates on the outside of the housing. Signal lines and wires are then connected. After the wiring is completed, the mounting plates and circuit boards are pushed back into the housing as a whole. This makes the installation operation more convenient. Moisture filter cotton is also provided to dry and filter the gas entering the housing, reducing the damage of moisture to the internal circuit boards and electronic components.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] like Figures 1 to 4 As shown, a modular high-frequency switch 12 power supply device includes a housing 1, a door 2, a slide rail 3, and a mounting plate 4. The mounting plate 4 is slidably installed in the slide rail 3. Multiple mounting plates 4 are provided. The internal circuit boards and electronic components of the high-frequency switch 12 power supply are classified and installed on multiple mounting plates 4 according to their functions or sizes. In the above process, the mounting plate 4 can be pulled out to the outside of the housing 1. The circuit boards and electronic components are installed on the corresponding mounting plates 4 on the outside of the housing 1, and signal lines and wires are connected. After the wiring is completed, the mounting plate 4 and the circuit board are pushed back into the housing 1 as a whole, which makes the installation operation more convenient.

[0027] like Figure 1 and Figure 2 As shown, the side wall of the outer casing 1 is also provided with an ammeter 11, a voltmeter, a control panel 13, and a rotary switch 12.

A ring is attached to the arc-shaped plate 9, and a water vapor filter cotton 14 is provided on the ring.

[0029] The air containing moisture first passes through the water vapor filter cotton 14 before reaching the fan 8. The water vapor filter cotton 14 absorbs the moisture in the gas, reducing the moisture content of the gas entering the outer casing 1 and making the gas drier, thus providing a drying and protective effect for the internal circuitry.

[0030] The protective cover 7 has mounting ears on both sides, and the arc plate 9 also has mounting ears. The arc plate 9 is fixed to the protective cover 7 with bolts. When cleaning and replacing the filter cotton, unscrew the bolts and pull out the arc plate 9 to clean the water vapor filter cotton 14.
