Description

Technical Field

[0001] The utility model relates to the technical field of aluminum heat sinks, in particular to a detachable aluminum heat sink. Background Art

[0002] A heat sink is a device that dissipates 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 computer's CPU central processing unit requires a fairly large heat sink, as do power tubes, line tubes, and power amplifier tubes in televisions. Generally, a heat sink should be coated with a layer of thermally conductive silicone grease on the contact surface between the electronic components and the heat sink during use, so that the heat generated by the components can be more effectively transferred to the heat sink and then dissipated into the surrounding air through the heat sink. Among the many types of heat sinks, aluminum heat sinks are popular among people for their beautiful appearance, light weight, good heat dissipation performance, and good energy-saving effects.

[0003] There are roughly two structures of common heat sinks on the market: the first type of heat sink is an integral whole. When a heat sink is damaged, it cannot be replaced individually and the entire heat sink needs to be replaced, which results in high cost. The second type of heat sink can replace the heat sink individually, but the heat sink removal and installation steps are too complicated and replacement is too troublesome, which will delay work progress and cause unnecessary losses.

[0004] Therefore, we propose a detachable aluminum heat sink to solve the above problems. Utility Model Content
