Description
Technical Field
[0001] The utility model relates to the technical field of power supply equipment, in particular to a water-cooled power rectifier. Background Art
[0002] A high-frequency rectifier is a rectifying device—simply put, a high-frequency switching power supply that converts alternating current (AC) into direct current (DC). It has two main functions: first, it converts AC into direct current (DC), filtering it before supplying it to the load or inverter; second, it provides charging voltage for the battery. Therefore, it also acts as a charger.
[0003] Currently, most commonly used high-frequency rectifier power supplies adopt a decentralized structural layout to produce and assemble complete power supplies. Various required components are distributed and fixed inside the chassis through the space inside the chassis. For example, the power meter, radiator, cooling fan, and the positive and negative copper plates of the power output are all mixed and fixed on the chassis. The decentralized layout results in a large chassis area. Various electronic components require a large number of connecting wires and terminals to connect with each other, resulting in high material and labor costs, long production cycles, and only manual assembly production.
[0004] Existing power rectifiers use a cooling fan on the heat dissipation holes on the side to replace the high-temperature air inside with the outside air to dissipate heat inside the power rectifier. However, after long-term use, a large amount of dust accumulates in the heat dissipation duct, resulting in a decrease in heat dissipation efficiency. The power rectifier needs to be disassembled, the dust in the duct needs to be cleaned, and then the power rectifier needs to be reinstalled, which is time-consuming and labor-intensive. Utility Model Content

The opening of the heat dissipation channel is located on one side of the sealing plate, and the heat dissipation channel outlet is located in the middle of the two sealing plates.
[0008] Preferably, a guide hole communicating with the heat dissipation channel outlet is formed near the center of one end of one sealing plate near the heat dissipation strip, and a guide groove communicating with the guide hole is formed on the side of the sealing plate away from the heat dissipation channel opening.
[0009] Preferably, the liquid cooling assembly includes a liquid inlet head and a liquid discharge head arranged on the bottom end face of the rectifier body, and a liquid cooling component arranged outside the rectifier body and introducing the coolant through the liquid inlet head and discharging it from the liquid discharge head. One end of the liquid inlet head and the liquid discharge head passes through the bottom end of the rectifier body and the sealing plate between the two sealing plates, and are respectively connected to the two ends of the bottom end face of the heat dissipation strip; a liquid cooling channel is opened in the heat dissipation strip along the length direction, which is connected to the inside of the liquid inlet head and the liquid discharge head respectively.
[0010] Preferably, the heat dissipation strip is a spiral strip made of copper, and the top and bottom side surfaces of the heat dissipation strip are tightly fitted with the adjacent end surfaces of the two sealing plates.

[0020] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific embodiments and drawings. However, the following embodiments are only preferred embodiments of the present invention and are not exhaustive. Based on the embodiments in the implementation manner, other embodiments obtained by those skilled in the art without creative work are all within the scope of protection of the present invention.
[0021] See also Figure 1-4 A water-cooled power rectifier includes a rectifier body 1 with a mounting groove 5 formed on its top end face, a mounting plate 2 detachably mounted on the opening of the mounting groove 5, components arranged in the mounting groove 5, and a heat dissipation mechanism arranged in the mounting groove 5. The heat dissipation mechanism includes a heat dissipation plate 6 detachably mounted on the bottom wall of the mounting groove 5 and having a heat dissipation groove 11 formed on its bottom end face, two sealing plates 12 parallel to each other and arranged in the heat dissipation groove 11, a heat dissipation bar 13 arranged between the sealing plates 12 and having top and bottom side surfaces respectively connected to adjacent end faces of the two sealing plates 12, an air intake assembly arranged in the mounting groove 5 and controlling the air inside the heat dissipation groove 11 to pass through the heat dissipation channel, and a liquid cooling assembly arranged on the rectifier body 1 and controlling the flow of coolant in the heat dissipation bar 13.
[0022] The heat dissipation strip 13 is in a spiral structure and forms a heat dissipation channel with the two sealing plates 12 . The heat dissipation channel opening is located on one side of the sealing plate 12 , and the heat dissipation channel outlet is located in the middle of the two sealing plates 12 .
[0023] like Figure 1-4As shown, the heat dissipation strip 13 with a spiral structure is clamped by two sealing plates 12, and a heat dissipation channel with a spiral line structure in the length direction is formed between the heat dissipation strip 13 and the two sealing plates 12, and the air intake component is cooperated to drive the air into the heat dissipation channel. The air flows inside the heat dissipation channel and drives the coolant to flow in the heat dissipation strip 13 through the liquid cooling component, so that when the air flows inside the heat dissipation channel, the heat in the air is transferred to the coolant through the heat dissipation strip 13, thereby facilitating the stable circulation and heat dissipation of the air in the installation slot 5, which can conveniently dissipate the heat of the power rectifier and avoid the situation where the outside air enters the power rectifier and causes dust to enter.
[0024] The heat dissipation strips 13 are made of heat-conducting material, and the coolant is water.
[0025] A guide hole 15 communicating with the heat dissipation channel outlet is formed at the center of one end of one sealing plate 12 near the heat dissipation bar 13 , and a guide groove 16 communicating with the guide hole 15 is formed on the side of the sealing plate 12 away from the heat dissipation channel opening.
[0026] The liquid cooling assembly includes a liquid inlet head 3 and a liquid discharge head 4 arranged on the bottom end face of the rectifier body 1, and a liquid cooling part arranged outside the rectifier body 1 and introducing the coolant into the liquid discharge head 4 through the liquid inlet head 3. One end of the liquid inlet head 3 and the liquid discharge head 4 passes through the bottom end of the rectifier body 1 and the sealing plate 12 between the two sealing plates 12, and is respectively connected to the two ends of the bottom end face of the heat dissipation strip 13; a liquid cooling channel is opened in the heat dissipation strip 13 along the length direction, which is respectively connected to the inside of the liquid inlet head 3 and the liquid discharge head 4.
[0027] like Figure 3-4 As shown, the liquid cooling component can use a micro water pump to control the water flow through the liquid inlet head 3 to introduce the coolant into the heat dissipation strip 13 for flow, thereby facilitating the air in the installation slot 5 to pass through the heat dissipation channel. The heat in the air is transferred to the coolant through the heat dissipation strip 13, and the coolant is driven to flow under the action of the micro water pump, so that the temperature in the installation slot 5 can be circulated and dissipated, avoiding the situation in the prior art where an opening is directly opened on the side of the rectifier body 1 and a fan is set in the opening for air exchange, which causes dust in the outside air to enter the rectifier body 1. The heat dissipation of the power rectifier can be convenient, and the situation in which dust is entered into the power rectifier due to the outside air entering the power rectifier can be avoided.
[0028] The heat dissipation strip 13 is a spiral strip made of copper, and the top and bottom side surfaces of the heat dissipation strip 13 are tightly fitted with the adjacent end surfaces of the two sealing plates 12 .
[0029] By adopting the spiral strips made of copper, it is easy to ensure that when the air flows in the heat dissipation channel, the heat in the air is transferred to the coolant through the heat dissipation strips 13. When the air circulates in the installation groove 5 and flows in the heat dissipation channel, the heat dissipation of the components in the installation groove 5 is ensured, ensuring that the rectifier body 1 can be used normally for a long time.
[0030] The heat dissipation mechanism also includes a connecting pipe 7 which is symmetrically fixed on the side of the heat dissipation plate 6 and has a bottom end face provided with a connecting groove 10 which is connected to the inlet and outlet of the heat dissipation channel respectively, and a connecting column 8 which is detachably mounted on the end portion of the connecting pipe 7 away from the heat dissipation plate 6 and has a bottom end face provided with an air guide groove which is connected to the inside of the connecting groove 10. A plurality of through holes 9 which are evenly distributed on the surface of the connecting column 8 and are connected to the inside of the air guide groove.
[0031] The air intake assembly includes a cooling fan 14 disposed in one of the air guide grooves.
[0032] like Figure 3-4 As shown, by rotating the cooling fan 14, the air in the installation slot 5 is driven into the heat dissipation channel, which can ensure that the air circulates and flows in the heat dissipation channel, and the heat in the air in the heat dissipation channel is stably dissipated through the heat dissipation strips 13, ensuring that the heat generated by the components in the installation slot 5 is stably circulated and dissipated.
[0033] The rectifier body 1 is provided with a power supply to drive the cooling fan 14 to rotate and drive the micro water pump to work.
