Heading tablets are a device for the heat dissipation of the easy -to -get heat -heating electronic component in the electrical appliance. Most of them are aluminum alloy, brass or bronze into plate -like, chip -shaped, and multi -chip, such as the CPU central processor in the computer.The heat sink, the power supply tube, the row management, and the amplifier tube in the TV must use the heat sink.Generally, the heat dissipation tablets should apply a layer of thermal silicon grease in the contact surface of the electronic component and the heat sink to make the calories emitted by the component to the heat sink more effectively, and then distribute it to the surrounding air through the heat sink.
What kind of material is good?
The radiator material refers to the specific material used by the heat sink.The thermal conductivity of each material is different. It is arranged from high to low according to thermal conductivity, namely silver, copper, aluminum, steel.The commonly used heat dissipation tablets are copper and aluminum alloy, each with its own advantages and disadvantages.Copper has good thermal conductivity, but the price is more expensive, the processing is difficult, and the weight is too large (many pure copper radiator exceeds the restrictions on weight of the CPU), the thermal capacity is small, and it is easy to oxidize.The pure aluminum is too soft and cannot be used directly. The aluminum alloy that is used can provide sufficient hardness. The advantage of aluminum alloy is low price and light weight, but thermal conductivity is much worse than copper.Some radiator takes the director each, and a copper plate is embedded in the base of the aluminum alloy radiator.
Self -made radiator
1. According to the edge length of the hot chip, take two sections of the book -order needle.2. Cross the two -segment script acupuncture (a little silicone in the middle) to form a box, just cover the chip.3. Carefully bent inward, leave the gap flowing air, and try to ensure heat dissipation as much as possible.4. Put the bottom of the radiator with heat dissipation silicone and stick to the hot chip.
