Description

Technical Field

[0001] This utility model relates to the field of rectifier heat dissipation, and in particular to a rectifier heat dissipation device. Background Technology

[0002] The main application of rectifiers is to convert AC power to DC power. Since all electronic devices need to use DC, but the power company's power supply is AC, unless batteries are used, all electronic devices must have rectifiers inside their power supplies. This is especially true for large equipment, where rectifiers are installed inside control cabinets. Heat dissipation of the rectifier is achieved by adding fans and heat sinks to the rectifier. Usually, the heat sinks are installed on one side of the rectifier, which only conducts heat and ventilates the heat dissipation surface. Other sides cannot be treated at the same time. Moreover, the heat dissipation channels of the heat sinks are fixed and cannot be adjusted, resulting in poor flexibility. Utility Model Content

Detailed Implementation

[0017] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are some embodiments of this utility model, but not all embodiments.

[0018] The following is combined Figures 1 to 3 The rectifier heat dissipation device provided in this embodiment will be further described as follows:

[0019] Please refer to Figure 1 The present invention provides a rectifier heat dissipation device, including a main heat sink 1, a fan assembly 2 and at least two guide vanes 3; the at least two guide vanes 3 are detachably installed on one side of the main heat sink 1 and are disposed between the fan assembly 2 and the main heat sink 1, and the at least two guide vanes 3 form a plurality of air ducts, which can enable the at least two guide vanes 3 and the main heat sink 1 to dissipate heat quickly.

[0020] "At least two" includes two or more cases.

[0021] A rectifier body 6 is installed on the other side of the main heat sink 1. The rectifier body 6 usually has one side as a heat-conducting surface to conduct its internal heat out and transfer it to the main heat sink 1 for heat conduction and heat dissipation. Thermal grease is usually applied between the heat-conducting surface and the main heat sink 1 to increase its thermal conductivity.

[0022] It should be noted that the other side of the main heat sink 1 is the side away from the air guide 3.

[0023] The rectifier body 6 has U-shaped heat sinks 4 on both sides. The U-shaped heat sinks 4 can be detachably installed on the main heat sink 1. The outer side of the U-shaped heat sink 4 contacts the outer wall of the rectifier body 6, and the U-shaped slot of the U-shaped heat sink 4 faces the main heat sink 1. The main heat sink 1 inside the U-shaped heat sink 4 has several flow-guiding holes 8.

[0024] like Figures 1-3 As shown, embodiments of this utility model also disclose the following more optimized specific structures:

[0025] The fan assembly 2 is equipped with a fan bracket 9, which is installed on the main heat sink 1 with screws. The fan bracket 9 quickly dissipates heat from the main heat sink 1, the air guide 2 and the U-shaped side heat sink 4 through airflow.

[0026] A pressure strip hole 12 is provided on the side of the U-shaped heat sink 4 near the rectifier body 6. Through the pressure strip hole 12, a side airflow heat dissipation channel is formed on the side of the rectifier body 6 to improve heat dissipation efficiency.

[0027] A side-pressure heat-conducting strip 5 is connected to the U-shaped side heat sink 4. The side-pressure heat-conducting strip 5 is provided with a crimping screw groove 10. A crimping screw 11 is inserted into the crimping screw groove 10. The side-pressure heat-conducting strip 5 is fixed to the main heat sink 1 by the crimping screw 11. The length of the crimping screw groove 10 is greater than the diameter of the crimping screw 11, so that the side-pressure heat-conducting strip 5 can have a certain range of motion before being pressed.

[0028] The heat-conducting surface on the rectifier body 6 is fixed to the main heat sink 1 by the body fixing screws 7.

[0029] The flow guide plate 3 consists of a wind baffle plate 31 and a transfer pressure plate 33 connected to the edge of the wind baffle plate 31. The wind baffle plate 31 and the transfer pressure plate 33 are arranged in an L-shape. The transfer pressure plate 33 has a shallow groove 34 for applying silicone grease on the side near the main heat sink 1. The transfer pressure plate 33 has a pressure plate hole 32 for easy fixing with screws. The main heat sink 1 has several screw slots on the side near the flow guide plate 3 to facilitate the disassembly and installation of different sets of flow guide plates 3.

The number of guide vanes 3 can be set according to the thermal effect of the rectifier. It is easy to disassemble and install. Each guide vane is provided with a shallow groove for silicone grease to increase the heat conduction effect. At the same time, the two sides of the rectifier body 6 are also provided with heat conduction and airflow heat dissipation structures to improve the overall heat dissipation effect. The detachable structure improves the flexibility of overall use.
