Description

Technical Field

[0001] The utility model relates to a high-frequency switch rectifier with high voltage stabilization accuracy, belonging to the technical field of high-frequency switch rectifiers. Background Art

[0002] In the prior art, for example, a utility model with publication number 201922342781.3 discloses a modular high-frequency switching power supply device. By means of two sets of mounting plates arranged inside the shell, electronic components can be classified and installed in a modular manner. At the same time, the shell and the cover plate are fixed with bolts, which makes disassembly and assembly convenient. In addition, during use, a heat dissipation fan outside the shell is used for air cooling to stabilize the operating temperature of the electronic components inside the shell.

[0003] Similar to the above application, there are still some shortcomings:

[0004] 1. Although the heat dissipation holes on the shell can speed up the heat dissipation effect of the device during use, dust will also enter the shell and cover the electronic components. Dust will accumulate over a long period of time, affecting the heat dissipation effect of the components and the operating load of the fan, resulting in increased jitter inside the device and reduced voltage stabilization accuracy.

[0005] 2. During the connection process, the wire is plugged into the device, and the outside of the wire is not fixed, which affects the stability of the connection;

[0006] Therefore, a high-frequency switching rectifier with high voltage stabilization accuracy is designed to optimize the above problems. Utility Model Content

[0026] The overall working principle is as follows: before the device is used, the connecting wire is plugged into the plug connector 12, and the line fixing mechanism 13 is used to stabilize the position of the wire. In addition, during use, the circulating water pump 9 and the cooling fan 5 are started. The cooling fan 5 circulates the gas inside the shell 1 counterclockwise. At the same time, the circulating water pump 9 draws the coolant inside the circulating water tank 8 into the water cooling pipe 6 to take away the heat inside the radiator 4, and performs water cooling to ensure that the temperature inside the shell 1 is stable. In addition, it effectively prevents external dust from entering the shell 1, ensures the cleanliness of the surface of the electronic components, and accelerates the heat dissipation during use.

[0027] In this embodiment, a semiconductor refrigerator 10 is provided outside the circulating water tank 8 , a cold end of the semiconductor refrigerator 10 is attached to the circulating water tank 8 , and a hot end of the semiconductor refrigerator 10 is located outside the fixed chamber 7 .

[0028] Partial working principle: When the coolant circulates inside the circulating water tank 8, in order to ensure the heat dissipation effect, the semiconductor refrigerator 10 can be turned on to cool down the inside of the coolant.

[0029] In this embodiment, a gap is left between the top of the radiator 4 and the inner top of the cover plate 11 , and the top of the cover plate 11 is evenly provided with heat dissipation grooves along the length direction.

[0030] Partial working principle: when the heat dissipation fan 5 controls the circulation of the gas inside the housing 1, the gas flows counterclockwise and adheres to the surface of the cover plate 11, and the contact area between the top of the cover plate 11 and the outside is increased through the heat dissipation groove, so the cooling effect is better.

[0031] In this embodiment, mounting holes are provided at the ends of both sides of the cover plate 11 , and the housing 1 and the cover plate 11 are connected by screws.

[0032] Partial working principle: During the assembly process of the device, screws pass through the mounting holes on the cover plate 11 and are fixedly connected to the side of the housing 1, making assembly more convenient.

[0034] Partial working principle: When the control device is moved, it is more convenient to carry it by holding the handle, and the rubber pad can be used to stabilize the placement during the placement process.

[0035] In this embodiment, the line fixing mechanism 13 includes an L-shaped plate 14, a limiting groove 15, a mounting groove 16, a clamping plate 17, a screw 18, a connecting rod 19 and a nut 20. The L-shaped plate 14 is fixed to the outer side of the cover plate 11. The end surface of the L-shaped plate 14 is evenly provided with limiting grooves 15 aligned with the plug connector 12. The inside of the L-shaped plate 14 is provided with a mounting groove 16. The upper and lower sides of the limiting groove 15 are hingedly installed with clamping plates 17. The side edges of the L-shaped plate 14 are evenly rotatably installed with screws 18, and the screws 18 extend to the inside of the mounting groove 16. The end of the screw 18 is located between the two groups of clamping plates 17. A nut 20 is threadedly installed on the screw 18. The upper and lower sides of the nut 20 are hingedly installed with connecting rods 19 with the ends of the clamping plates 17.

[0036] Local working principle: After the connecting wire is connected to the plug connector 12, the connecting wire is pushed from the open end of the limiting groove 15 to the inner end of the limiting groove 15, and then the screw 18 on the outside of the limiting groove 15 is tightened. The nut 20 moves along the length direction of the screw 18, and the connecting rod 19 is used to push the inner ends of the two sets of clamps 17 located in the installation groove 16 outward. At this time, the other end of the clamp 17 will press the connecting wire to ensure the stability of the connecting wire.

[0037] In this embodiment, an adjustment block is fixed to one end of the screw rod 18 away from the interior of the installation slot 16, and the adjustment block is provided with anti-slip grooves.

[0038] Partial working principle: During the rotation of the screw 18, the existence of the adjustment block enables the rotation of the screw 18 to be controlled manually, and the adjustment is convenient.
