Die Cast Aluminum Heat Sink
The Die Cast Aluminum Heat Sink is a device that dissipates heat for the heat-prone electronic components in the electrical appliance. The power tube in the machine, the line tube, and the power amplifier tube in the power amplifier must use heat sinks. Generally, the heat sink should be coated with a layer of thermal grease on the contact surface between the electronic components and the heat sink during use, so that the heat emitted by the components can be more effectively conducted to the heat sink, and then dissipated into the surrounding air through the heat sink.
As far as the heat sink material is concerned, the thermal conductivity of each material is different, and they are arranged in descending order of thermal conductivity, namely silver, copper, aluminum, and steel. However, it would be too expensive to use silver as a heat sink, so the best solution is to use copper. Although aluminum is much cheaper, it is obviously not as thermally conductive as copper (about 50% of copper).
At present, the commonly used heat sink materials are copper and aluminum alloy, both of which have their own advantages and disadvantages. Copper has good thermal conductivity, but it is expensive, difficult to process, heavy (many pure copper heat sinks exceed the weight limit of CPU), small heat capacity, and easy to oxidize. Pure aluminum is too soft to be used directly. Only aluminum alloys are used to provide sufficient hardness. The advantages of aluminum alloys are low price and light weight, but the thermal conductivity is much worse than that of copper. Some radiators take their own advantages and embed a copper plate on the base of the aluminum alloy radiator.
For ordinary users, the use of Die Cast Aluminum Heat Sink is enough to meet the cooling needs.
