Description
Technical field
The utility model belongs to fin field, is specially that one kind is used to accelerate electronics, electrical equipment and some other electronics
The mica copper aluminium radiator fin of equipment heat conduction velocity.
Background technology
With the development of the assembling densification of integrated technology and microelectronics, the heat produced by electronic equipment accumulates rapidly,
Increase.And as the rise of electronic component self-temperature can directly result in the performance and reliability decrease of itself, therefore energy
No timely radiating, which turns into, influences the key factor of its service life.Traditional electronics, electrical equipment etc. radiating be typically all by copper sheet,
Aluminium flake is realized, but the making of copper sheet, aluminium flake is relatively cumbersome, and cost is higher, thermal diffusivity is general, and to electric electricity
Performance tool has a certain impact.
Mica is the general name of a class hydrous alumino silicates class, and it has electrical strength high, and dielectric loss is low, sheet resistance and
Volume resistance is high, with heat resistance, water resistance, chemical stability, high resilience, high fissility, very big fingerprinting stress and anti-
The excellent properties such as Zhang Qiangdu, available for the radiating insulating of electronic component, but itself is impure more so that its aspect of performance
Have a greatly reduced quality, cause its performance also Shortcomings, its material need to be improved, combination property need further to improve and
Improve, thus, purity is more preferable, and more advantageous relative to natural mica product by special finished mica splitting product,
Therefore replaced natural mica splitting in many fields.
Utility model content
The technical problem that the utility model is solved is to provide a kind of mica fin, to solve in above-mentioned background technology
Shortcoming.
The technical problem that the utility model is solved is realized using following technical scheme：
A kind of mica fin, including base material, wherein, the base material is mica sheet, and on the two sides of this mica sheet
