Semi circle aluminum heat sink

September 30, 2019

A semi circle aluminum heat sink is not an aluminum circle but an aluminum profile of the semi-circle shape, used to exchange heat in machines or electronic units.

A semi circle aluminum heat sink is a device for dissipating heat from the heat-generating electronic components in the electrical appliance. A heat sink is mostly made of aluminum alloy, brass or bronze, and is made into a plate shape, a sheet shape, a multi-chip shape, etc., such as a CPU central processor in a computer to be used considerably. The heat sink, the power tube in the TV, the tube, and the power amplifier tube in the power amplifier must use the heat sink. Generally, the heat sink is coated with a layer of thermal grease on the contact surface of the electronic component and the heat sink, so that the heat emitted by the component is more effectively transmitted to the heat sink and then radiated to the surrounding air through the heat sink. The commonly used heat sink materials are copper and aluminum alloy, both of which have their advantages and disadvantages. Copper has good thermal conductivity, but it is expensive, difficult to process, and too heavy (many pure copper radiators exceed the CPU’s weight limit), heat capacity is small, and it is easy to oxidize. Pure aluminum is too soft to be used directly. The aluminum alloy used can provide sufficient hardness. The advantage of aluminum alloy is low price and light weight, but the thermal conductivity is much worse than copper. Some radiators take their own strength and embed a piece of copper on the base of the aluminum alloy radiator. For the average user, the use of aluminum heat sinks is enough to meet the cooling needs.

If you want to customize semi circle aluminum heat sinks, you should first check the strength of a company first. Small processing plants are generally required to be outsourced, so that quality and delivery cannot be met. You should check the mold development capabilities. Generally, the aluminum factory, which has not been in business for a long time, does not have the ability of mold design, and the mold is not guaranteed. It is bound to be reworked many times, which greatly reduces the work efficiency. Secondly, you should get clear whether the raw materials produced by the enterprise can be guaranteed. If the raw materials cannot be guaranteed, the post-process will bring about numerous problems. More formal aluminum companies will also have material reports. The following depends on the production capacity of the enterprise. If a company’s production capacity is insufficient, it will inevitably affect the delivery period.
