[0002] A heat sink is a device for dissipating heat from heat-prone electronic components in electrical appliances. It is mostly made of aluminum alloy, brass or bronze in the shape of plates, sheets, or multiple sheets. For example, a CPU in a computer requires a relatively large heat sink, and power tubes, line tubes, and power amplifier tubes in a television all require heat sinks. Generally, a heat sink should be coated with a layer of thermal conductive silicone grease on the contact surface between the electronic component and the heat sink during use, so that the heat generated by the component can be more effectively transferred to the heat sink and then dissipated to the surrounding air through the heat sink. When the heat sink is processed and formed, a deburring device is required to clean the surface of the heat sink. The current deburring structure is relatively simple, and the heat sink needs to be fixed multiple times when multiple surfaces of the heat sink are polished, which makes it inconvenient to use. Therefore, a surface deburring device for heat sink processing is proposed. Utility Model Content
