Description

Technical Field

[0001] The utility model relates to a pulse-type high-voltage power supply. Background Art

[0002] The current marine industry has an urgent need for sterilization, disinfection, and exhaust gas treatment. With the continuous advancement of modern production technology, various electrical equipment is becoming increasingly sophisticated, complex, and miniaturized. Previous low-frequency, high-voltage pulse power supplies primarily used pulse transformer step-up methods. However, due to the large size of the transformers, this approach struggled to meet industrial production requirements. Furthermore, miniaturizing the transformer, as is common sense, reduces the surface area of a cube several times, just as the side length of the cube is halved.

[0003] Therefore, a miniaturized high-voltage power supply structure that is more convenient for heat dissipation is needed. Utility Model Content

[0004] The purpose of this utility model is to solve the above shortcomings of the existing technology and provide a pulsed high-voltage power supply with a uniquely designed housing, which not only facilitates wiring but also effectively solves the problem of equipment heat dissipation. The following is a specific solution:

[0005] A pulsed high-voltage power supply includes a first shell and a second shell, both of which are arched in shape. The second shell clamps the first shell via a fixing structure. At least one accommodating chamber and at least one opening are provided between the arched outer wall of the first shell and the arched outer wall of the second shell, and the opening is connected to the accommodating chamber.

[0006] The first housing includes an upper top plate and two side plates, which are arranged at 90 degrees to each other. Mounting plates are provided on the narrow sides of the upper top plate and the two side plates, each with mounting holes. The first housing also includes a lower bottom plate and two side panels, which are arranged at 90 degrees to each other. The length of the lower bottom edge of the side panel is smaller than the length of the upper bottom edge. The side panels are provided with perforations that mate with the mounting holes and are secured with bolts. This structure and fixing method allows for quick assembly and disassembly without damaging the housing, saving maintenance time and costs.

[0007] In order to further enhance the heat dissipation effect, a heat dissipation hole is provided on the upper side of the first housing, and at least one heat dissipation device is provided on the heat dissipation hole.

[0008] The heat dissipation device is a fan, and the forced convection heat dissipation method of the fan can quickly discharge the internal heat, keep the equipment within a suitable operating temperature range, and effectively extend the service life of the equipment.

[0009] At least four studs are provided at the bottom of the second housing, and circuit boards are mounted on the four studs. For better heat dissipation, the circuit boards are arranged on the studs.

[0010] The interfaces on the circuit board are all arranged toward the opening, taking into account both wiring and heat dissipation of the circuit board.

[0011] The first shell and the second shell are both made of aluminum alloy, which not only improves the overall strength of the device but also reduces the weight of the device, making it easier to transport and install.

[0012] Beneficial effects: The arched design forms a chamber and an opening between the first and second shells, effectively improving heat dissipation efficiency. This structure facilitates natural convection of hot air within the chamber, thereby accelerating heat dissipation and avoiding equipment damage caused by local overheating.

[0013] Compared with the traditional flat or box-type structure, the arched design is more beautiful, and the first shell and the second shell that are separately arranged are fixed by a fixing structure, which makes installation and disassembly more convenient. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0020] In order to deepen the understanding of the present invention, the present invention will be further described in detail below with reference to embodiments and drawings. The embodiments are only used to explain the present invention and do not constitute a limitation on the scope of protection of the present invention.

[0021] In this embodiment:

[0022] Please see Figure 1-Figure 3 A pulsed high-voltage power supply includes a first shell 1 and a second shell 2. The first shell 1 and the second shell 2 are both arched in shape. The second shell 2 clamps the first shell 1 through a fixing structure 3. At least one accommodating chamber 4 and at least one opening 5 are provided between the arched outer wall of the first shell 1 and the arched outer wall of the second shell 2. The opening 5 is connected to the accommodating chamber 4.

[0023] The first shell 1 includes an upper top plate 12 and two side plates 13, which are arranged at 90 degrees between the upper top plate 12 and the two side plates 13, and the narrow sides of the upper top plate 12 and the two side plates 13 are provided with mounting plates 14, and the mounting plates 14 are provided with mounting holes 15. The first shell 1 includes a lower bottom plate 21 and two side panels 22, which are arranged at 90 degrees between the lower bottom plate 21 and the two side panels 22, and the side length of the lower bottom edge of the side panel 22 is smaller than the side length of the upper bottom edge. The side panel 22 is provided with a through-hole 23, and the through-hole and the mounting hole 15 correspond to each other and are fixed by bolts. The upper side of the first shell 1 is provided with a heat dissipation hole 16, and the heat dissipation hole 16 is provided with at least one heat dissipation device 17, and the heat dissipation device 17 is a fan. At least four studs 24 are provided at the bottom of the second shell 2, and a circuit board is installed on the four studs 24, characterized in that the interfaces on the circuit board are all set towards the opening 5, and the materials of the first shell 1 and the second shell 2 are both aluminum alloy.

[0024] The circuit board includes four terminals, a program burning port, and a digital display. The terminals include power input, alarm output, and load connections. The digital display displays real-time output voltage, output current, and device temperature. If the temperature exceeds a preset value, a fan automatically activates for effective cooling. By burning a pre-programmed program into the control board, the board's built-in algorithm collects, analyzes, and calculates current voltage and current data, displaying it in real time on the digital display. This power supply is primarily controlled by an APM32F103RCT6 microcontroller, boasting a maximum CPU speed of 96MHz, 16KB-1MB flash memory, a variety of control peripherals, a full-speed USB interface, and CAN. This device utilizes a leading ARM Cortex-M3 core microcontroller, offering state-of-the-art integration and low power consumption. Its superior performance and abundant system resources ensure fast and efficient operation of the entire control board and its versatile functionality. The control board features two normally closed / normally open signals, one for operational and one for fault conditions.

[0025] The second shell 2 and the first shell 1 of the pulsed high-voltage power supply adopt a trapezoidal design in structure. The advantages of the front and rear openings 5 are that they facilitate the heat dissipation of internal components and provide convenience for external wiring of the device. A fan is installed on the upper cover of the device. When the internal temperature of the device reaches a preset value, its internal program can drive the fan to cool down. The fan will turn on as the temperature rises and turn off as the temperature drops, realizing the automation and intelligence of temperature control.

[0026] Relying on the shell design this time, the heat dissipation of the rectifier bridge GBJ3506 and the field-effect transistor NCE20TD60BT is transferred to the shell using the heat sink. Combined with the previous fan, the performance of the equipment can be better guaranteed.

[0027] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model and are not limiting. Although the utility model is described in detail with reference to the preferred embodiments, ordinary technicians in this field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
