Technical Field

[0001] This utility model relates to the technical field of centralized heat dissipation devices for rectifiers, and in particular to a centralized heat dissipation device for rectifiers. Background Technology

[0002] A rectifier is an electronic component that converts alternating current (AC) into direct current (DC). It is commonly found in power supplies for electronic devices. Rectifiers can be classified into different types, such as mechanical, vacuum tube, and semiconductor types. Rectifiers generate heat during operation, so a cooling device is needed to cool them down in order to ensure stable operation.

[0003] Patent document CN 219205118 U discloses a rectifier heat dissipation device, including a base plate. A support plate is fixedly installed at the middle of the upper surface of the base plate. An adjusting rod is movably connected to the upper inner wall of the support plate, and mounting brackets are symmetrically sleeved on the outer wall of the adjusting rod. A bracket is fixedly installed at the upper end of the support plate, and a lifting rod is movably connected to the upper inner wall of the bracket. A heat dissipation frame is movably disposed at the lower end of the lifting rod, and the lower surface of the heat dissipation frame is coated with thermally conductive silicone grease. A motor is installed on the upper outer wall of the end of the heat dissipation frame, and a transmission rod is fixedly connected to the output shaft end of the motor. Main bevel gears are fixed at equal intervals on the outer wall of the transmission rod, and a fan mechanism is disposed on the inner wall of the heat dissipation frame next to the main bevel gears.

[0004] In the above technical solution, the internal heat is discharged through the fan blades by the heat dissipation frame. As a circulation component of the device, it is fixedly installed. Long-term use will cause dust to accumulate inside the heat dissipation frame, thereby affecting heat dissipation.

[0005] Therefore, we propose a centralized heat dissipation device for rectifiers to solve this problem. Utility Model Content
