Where can’t copper heat sinks be used?

Copper heat sink has its advantages, also have its disadvantages. As is often the case that distributors and manufacturers always introduce advantages of heat sink while the disadvantages are hardly mentioned. However those shortcomings are often the key to solving the heat sink problems.
Large heat sink has great demand for water quality of heat-supplying system. If it has a simple corrosion phenomenon in the unsafe heating system, chip heat sink manufacturers said that consumers should know whether the heat sinks match the residential heat-supplying system before their purchase.
Since water quality of those residential heat-supplying system can not reach the specification, recently companies have begun to take corresponding anti-corrosion measures.

Skived & Zipper fin

What is Skived fin heatsink? High power cooling, Alternative, Greater design flexibility Skived Fin Heat Sink ·  Skived heatsink   is a kind of heat dissipation device for electronic components in electrical appliances, mostly made of aluminum alloy, brass or bronze plate,multi-sheet, etc. If it is a side - blown heatsink, then take the chassis internal duct structure into consideration. Or let it blow heat sink directly if you have no idea about it, because general chassis in the level backboard position of CPU heatsinks  can have heat sink hole position. Installation of Skived ·  Heatsinks   should have a certain mechanical strength and pressure capacity,easy to install and combined into the required cooling area; Size should be small, less take up room area and space; Not easy to damage during installation; The manufacturing process is simple and suitable for mass production. Zipper fin heat sink  features &  Materials Simple mechanical locking structure, fewer

LED cold forging heat sink adopts advanced cold casting technology from Germany to produce pure aluminum and copper integrated heat sinks with high efficiency, environmental protection and beautiful appearance. Cold precision forging of cold forging heat sinks is a net forming process. The parts formed by this method have high strength and precision and good surface quality. Cold forging gear single weight up to more than 1kg, profile accuracy up to 7 level. The main principle of shunt forging is to establish a material shunt chamber or channel in the forming part of the blank or die. Cold forging cost has been widely used in many industries, such as LED, automobile, radio technology, military products, etc. In terms of cost protection and energy saving.  Cold forging technology has various advantages, such as good surface quality and high dimensional accuracy, which can replace some cutting and processing. Cold forging strengthens metals and strengthens parts. http
