What is a heat sinks

The heat sinks is a device that dissipates heat for the heat-prone electronic components in the electrical appliance. It is mostly made of aluminum alloy, brass or bronze into plate, sheet, multi-sheet, etc. The heat sink of the TV, the power tube in the TV, the line tube, and the power amplifier tube in the power amplifier must use the heat sink. Generally, the heat sink should be coated with a layer of thermal grease on the contact surface between the electronic component and the heat sink during use, so that the heat emitted by the component can be more effectively conducted to the heat sink, and then dissipated into the surrounding air through the heat sink.

Aluminum casting heat sinks

Although the price of aluminum extruded heat sinks is low and the manufacturing cost is also low, due to the limitation of the soft texture of aluminum itself, the ratio of the thickness of the fins to the height of the fins generally does not exceed 1:18, so each PC manufacturers are constantly increasing the heat dissipation area and keep the heat dissipation space unchanged. The manufacturers have proposed a more suitable solution to encrypt the fins to increase the number of fins; bend the fins to increase the heat dissipation Area; heating the aluminum ingot from a solid state to a liquid state through the mold, and then cooling it becomes the heat sink we want.

Embedded copper heat sinks

The most perfect solution to this compromise solution is the copper embedded technology pioneered by AVC. This is a harmonious unification of the advantages of fast heat conduction, high density and strong heat absorption capacity of copper and the advantages of traditional aluminum extrusion, such as light density, low price and convenient mass production.

Gear-Shaped Heat sinks


Today, when the requirements for heat dissipation are constantly increasing, the Japanese have begun to think of using thin and dense heat dissipation fins to fit the heat dissipation bottom plate with huge pressure. This technology can be arbitrarily combined and matched with copper and aluminum fins and copper and aluminum base plates, and also effectively avoids the disadvantage of new thermal resistance caused by uneven heat conduction of various solder pastes during the welding process. It enables customers to have more selectivity and diversity of thermal solutions. However, due to the particularity of its processing, the current mass production still has the problem that the cost is too high.

Copper cut heat sinks

After using the aluminum extruded heat sink for such a long time, no matter how we change our processing technology, it is difficult to meet the ever-increasing CPU calorific value. The coefficient is much larger than that of aluminum, and the thermal conductivity is doubled, which is of great benefit to our heat dissipation; however, since the hardness of copper is much greater than that of aluminum, it is a severe test for the manufacturing process during the processing. Therefore, the traditional extrusion molding process is no longer applicable to copper, and has to be processed in this cutting method.

Frequently Asked Question

Do you have any question?

A heat sink is a device that absorbs heat generated by an electronic component or chip. Among different types of heat sinks, two-phase forced convection cooling of high heat flux/high power electronics is one of the most effective thermal management methods.

Active radiators utilize forced air to increase fluid flow through the hot zone. Forced air is most often created by the movement of fans, blowers or even whole objects - for example the engine of a motorcycle is cooled by air from fins designed into the engine.

Radiators are divided into different categories according to different criteria. There are two main types of radiators, active radiators and passive radiators.
