Description

Aluminum radiating fin

Technical Field

The utility model relates to the technical field of cooling fins, in particular to an aluminum cooling fin.

Background

The radiating fin is a device for radiating the heat-generating electronic element in the power supply, and is mostly made of aluminum alloy, brass or bronze into a plate shape, a sheet shape, a multi-sheet shape and the like, for example, a CPU central processing unit in a computer needs to use a quite large radiating fin, and a power tube, a row tube and a power amplifier tube in a television need to use the radiating fin. In use, a layer of heat-conducting silicone grease is coated on the contact surface of the electronic element and the heat sink, so that heat emitted by the element is more effectively conducted to the heat sink and then emitted to the surrounding air through the heat sink. And aluminum fins are one of the common types.

The common aluminum radiating fin is usually arranged on a base (such as aluminum, etc.), the base is additionally arranged near a radiating structure of an electric appliance (such as a computer host, etc.), a layer of heat-conducting silicone grease is coated on the surface, when the electric appliance is electrified to start working, the heat generated inside is absorbed, and the heat is emitted into the surrounding air through the base, so that the common radiating fin works. The aluminum heat sink is typically mounted to the base by a mounting structure (e.g., expansion bolts, screws) and the base is also mounted to the appliance using the same mounting structure. The side plates are longitudinally arranged on the periphery of the top of the base, slots are longitudinally formed in the inner side faces of the side plates, and the corresponding sides of the aluminum radiating fins are inserted into the slots of the side plates for installation, so that the purpose of disassembly and installation is facilitated. However, since the heat sink absorbs and emits heat by means of its own surface area, the surface of the aluminum heat sink is partially inserted into the slot, which tends to reduce the surface area of the heat sink, thereby reducing the heat dissipation efficiency of the heat sink.
