Description

Technical Field

[0001] This utility model relates to the field of rectifier bridge technology, specifically to a high-efficiency heat dissipation rectifier bridge. Background Technology

[0002] A rectifier bridge typically carries a sufficiently large inductive load, thus preventing current discontinuity. In general applications, a smoothing reactor is connected to the load terminal of a rectifier bridge, allowing the load to be considered a constant current source. Multiple three-phase rectifier bridges are interconnected, allowing the harmonics generated by the rectifier bridge circuit to cancel each other out. Based on the type of rectifier transformer, they can be classified into traditional multi-pulse transformer rectifiers and autotransformer multi-pulse transformer rectifiers.

[0003] When using a rectifier bridge, heat dissipation fins need to be installed on the rectifier bridge. The heat dissipation components blow air onto the heat dissipation fins to speed up the heating efficiency. However, the heat dissipation fins do not have a cleaning function, which leads to a lot of dust on the heat dissipation fins and a poor heat dissipation effect. Utility Model Content

[0004] To address the shortcomings of existing technologies, this invention provides a high-efficiency heat dissipation rectifier bridge that has the advantage of cleaning the heat dissipation fins, thus solving the problem that the heat dissipation fins do not have a cleaning function.

[0005] This utility model discloses a high-efficiency heat dissipation rectifier bridge, including a mounting base. The bottom of the mounting base's inner cavity contains the rectifier bridge body, and both sides of the rectifier bridge body are provided with heat dissipation fins. Cleaning components are provided on both sides of the mounting base's inner cavity. Each cleaning component includes a movable plate located at the bottom of the outer side of the mounting base's inner cavity. Slider blocks are provided at both ends of the outer side of the movable plate. Sliding grooves adapted to the sliders are provided at both ends of both sides of the mounting base's inner cavity. A handle is provided on the outer side of the movable plate, extending through and to the outer side of the mounting base. Sliding grooves adapted to the handle are provided at both ends of both sides of the mounting base. The movable plate has a through groove, and a cleaning roller is provided on the inner side of the movable plate. When it is necessary to clean the heat dissipation fins, the handle is moved first, which drives the movable plate to move. The movable plate moves in conjunction with the sliding groove and slider on the mounting base. The handle moves in conjunction with the through groove on the mounting base, and the movable plate drives the cleaning roller to move. The cleaning roller can clean the dust on the surface of the heat dissipation fins. In this way, the heat dissipation fins have a better heat dissipation effect and avoid the situation where the heat dissipation fins do not have a cleaning function during use, resulting in a lot of dust on the heat dissipation fins and poor heat dissipation effect.

[0006] This utility model discloses a high-efficiency heat dissipation rectifier bridge, wherein heat dissipation components are fitted on both sides of the mounting base. The heat dissipation components include a heat dissipation shroud, which is fitted inside the mounting base. A motor is installed inside the heat dissipation shroud, and fan blades are installed at the output end of the motor. When high-efficiency heat dissipation is required, the motor first runs, driving the fan blades to rotate. The fan blades blow air towards the heat dissipation fins, which accelerates the heat dissipation of the heat dissipation fins and thus accelerates the heat conduction efficiency of the rectifier bridge body.

[0007] The present invention relates to a high-efficiency heat dissipation rectifier bridge, wherein an air inlet is provided on the outer side of the heat dissipation shroud, and a filter screen is provided in the inner cavity of the air inlet. Through the air inlet and the filter screen, when the air enters the heat dissipation shroud through the air inlet, the air can be filtered by the filter screen, so that the air inside the heat dissipation shroud is more effective during use.

[0008] The present invention relates to a high-efficiency heat dissipation rectifier bridge, wherein the connection between the two sides of the motor and the heat sink is fixedly connected by a fixing bracket, and the motor is located in the center of the inner cavity of the heat sink. The fixing bracket can fix the motor, thus improving the motor's performance during use and preventing the motor from shaking and becoming unstable.

[0009] The present invention relates to a high-efficiency heat dissipation rectifier bridge, wherein the top and bottom of the heat sink are fixedly connected to mounting plates, and the inner cavity of the mounting plates is fixedly connected to the mounting base by fixing bolts. The mounting plates and fixing bolts can fix the heat sink, thus improving the heat sink's performance during use and preventing the heat sink from shaking during use, which could lead to instability in the components inside the heat sink.

[0010] The present invention relates to a high-efficiency heat dissipation rectifier bridge, wherein the surface of the handle is covered with an anti-slip sleeve, and the surface of the anti-slip sleeve is provided with anti-slip threads. The anti-slip sleeve can prevent the handle from slipping when the user moves the handle up and down.

[0011] The present invention provides a high-efficiency heat dissipation rectifier bridge, wherein the inner side of the moving plate is provided with eight cleaning rollers, and the eight cleaning rollers are equally spaced on the inner side of the moving plate.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. When the heat dissipation fins need to be cleaned, the handle is moved first, which drives the moving plate to move. The moving plate moves in conjunction with the sliding groove and slider on the mounting base, and the handle moves in conjunction with the through groove on the mounting base. The moving plate drives the cleaning roller to move, and the cleaning roller can clean the dust on the surface of the heat dissipation fins. This makes the heat dissipation fins more effective and avoids the situation where the heat dissipation fins do not have a cleaning function, resulting in a lot of dust on the heat dissipation fins and poor heat dissipation.

[0013] 2. When efficient heat dissipation is required, the motor runs first, which drives the fan blades to rotate. The fan blades blow air towards the heat dissipation fins, which can accelerate the heat dissipation of the heat dissipation fins and thus accelerate the heat conduction efficiency of the rectifier bridge body. The mounting bracket can be used to fix the motor in place, which makes the motor perform better during use and prevents the motor from shaking and causing unstable operation. With the air inlet and filter, the air can be filtered as it enters the heat sink through the air inlet, resulting in better air quality during use. The heat sink can be fixed in place by mounting plates and fixing bolts, which makes the heat sink more effective during use and prevents the heat sink from shaking during use, which could lead to instability of the components inside the heat sink. The anti-slip sleeve prevents the handle from slipping, thus preventing it from falling off when the user moves the handle up and down. Attached Figure Description
