Description

Technical Field

[0001] This invention belongs to the field of rectifier technology, specifically relating to a rectifier with high heat dissipation performance. Background Technology

[0002] A rectifier is an electrical device that converts alternating current (AC) into direct current (DC). The core working principle of a rectifier is based on the unidirectional conductivity of a semiconductor diode. A diode only allows current to flow in one direction, from the anode to the cathode. When AC is input, the diode conducts during the positive half-cycle of the AC current, allowing current to flow. During the negative half-cycle, the diode is cut off, preventing current from flowing. Thus, after rectification by the diode, the output current becomes unidirectional direct current.

[0003] Rectifiers are connected to external wires via connectors, but current rectifiers lack protection at these connectors, making them prone to damage after prolonged use. Additionally, rectifiers convert some electrical energy into heat during operation. If this heat is not dissipated promptly, the rectifier's temperature will rise continuously, affecting its operational stability. The common cooling method for rectifiers is air cooling, but the cooling capacity of current rectifiers is relatively fixed and cannot be adjusted according to the rectifier's temperature.

[0004] Therefore, it is necessary to improve the existing technology to solve the above-mentioned technical problems. Utility Model Content

[0005] The purpose of this invention is to provide a rectifier with high heat dissipation performance, which can solve the problem that current rectifiers lack protection at the connectors, making the connectors prone to damage after long-term use.

[0006] The specific technical solution adopted in this utility model is as follows:

[0008] The present invention is further configured such that: grooves are symmetrically provided at both the front and rear ends of the upper side of the outer wall of the rectifier housing; limit blocks are symmetrically fixedly installed on the left and right sides of the outer wall of the rotating plate; and insertion blocks are simultaneously inserted into the two adjacent rotating plates.

It should be understood that the following text is merely used to describe one or more specific implementations of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.

[0023] like Figure 1-4 As shown, a high-heat-dissipation rectifier includes a rectifier housing 100, a rectifier body 110 fixedly installed inside the rectifier housing 100, a connector 120 fixedly installed on the upper end of the outer wall of the rectifier body 110, heat dissipation fins 200 symmetrically and linearly arranged on the left and right sides of the lower side of the outer wall of the rectifier housing 100, a bottom cooling fan 210 fixedly installed at the front end of the lower side of the outer wall of the rectifier housing 100, and a pair of rotating plates 300 rotatably connected to the left and right ends of the upper side of the outer wall of the rectifier housing 100. Each rotating plate 300 has an arc-shaped connecting sleeve 310 symmetrically fixedly connected to the upper end of the outer wall of each rotating plate 300. The heat dissipation fins 200 can dissipate heat from the bottom of the rectifier housing 100, and the bottom cooling fan 210 can blow air onto the heat dissipation fins 200 to improve the heat dissipation effect of the heat dissipation fins 200.

[0024] like Figure 1 and 2As shown, grooves 320 are symmetrically provided on both the front and rear ends of the upper side of the outer wall of the rectifier housing 100. Limiting blocks 330 are symmetrically fixed on the left and right sides of the outer wall of the rotating plate 300. The rotation angle of the rotating plate 300 can be limited by the grooves 320 and the limiting blocks 330. Insertion clips 340 are inserted into the two adjacent rotating plates 300. The rectifier body 110 is connected to the external wires through the connector 120. At the same time, the arc-shaped connecting sleeves 310 on both sides are closed by rotating the rotating plate 300, and the position of the rotating plate 300 is fixed by inserting the insertion clips 340 to protect the external wires connected to the connector 120. A fixing bracket 600 is fixedly installed at the lower end of the outer wall of the rectifier housing 100. The fixing bracket 600 has threaded holes 610. The fixing bracket 600 and the threaded holes 610 can be used to easily install fixing devices.

[0025] like Figure 2 and 5 As shown, U-shaped heat dissipation pipes 400 are linearly arranged and fixedly installed on the side wall of the rectifier housing 100. A connecting pipe 410 is fixedly installed at the front end of the outer wall of each U-shaped heat dissipation pipe 400. A side wall cooling fan 420 is fixedly installed at the front end of the outer wall of the connecting pipe 410. Exhaust pipes 430 are symmetrically fixedly connected to the rear end of the outer wall of the U-shaped heat dissipation pipe 400. By starting the side wall cooling fan 420, air can be pumped into the connecting pipe 410 and the U-shaped heat dissipation pipe 400 and discharged from the exhaust pipe 430. The air flowing through the U-shaped heat dissipation pipe 400 can carry away the heat on the side wall of the rectifier housing 100, thereby achieving further heat dissipation of the rectifier housing 100.

[0026] like Figure 1 and 3 As shown, a microcontroller 500 is fixedly installed on the lower end of the outer wall of the rectifier housing 100, and a temperature sensor 510 is fixedly connected to the upper end of the outer wall of the rectifier body 110. The microcontroller 500 is electrically connected to the temperature sensor 510 and the side wall cooling fan 420. The temperature sensor 510 can monitor the temperature of the rectifier body 110 and transmit the monitored temperature data to the microcontroller 500. The microcontroller 500 changes the number of side wall cooling fans 420 that need to be activated according to the monitored temperature of the rectifier body 110, thereby adjusting the heat dissipation intensity of the device. A filter 421 is fixedly connected to the input end of the side wall cooling fan 420. The filter 421 can prevent external dust and debris from entering the U-shaped heat dissipation pipe 400, avoiding blockage of the U-shaped heat dissipation pipe 400.

[0027] The working principle of this utility is as follows: First, the rectifier body 110 is connected to the external wires through the connector 120. At the same time, the rotating plate 300 is rotated to close the arc-shaped connecting sleeves 310 on both sides. The position of the rotating plate 300 is fixed by inserting the plug-in block 340, thus protecting the external wires connected to the connector 120.

[0028] When in use, the device dissipates heat from the bottom of the rectifier housing 100 through the heat dissipation fins 200, and improves the heat dissipation effect by blowing air onto the heat dissipation fins 200 by activating the bottom heat dissipation fan 210. At the same time, the device pumps air into the connecting pipe 410 and the U-shaped heat dissipation pipe 400 and discharges it through the exhaust pipe 430 by activating the side wall heat dissipation fan 420. The air flowing through the U-shaped heat dissipation pipe 400 can carry away the heat on the side wall of the rectifier housing 100, thereby achieving further heat dissipation of the rectifier housing 100. The device can also monitor the temperature of the rectifier body 110 through the temperature sensor 510 and transmit the monitored temperature data to the microcontroller 500. The microcontroller 500 adjusts the number of side wall heat dissipation fans 420 to be activated according to the monitored temperature of the rectifier body 110, thereby adjusting the heat dissipation intensity of the device.
