Device, serves important function in the radiation processes of power electronic equipment, and is widely used in actual product.But with
The increase of power electronic devices power, the method increasing heat dissipation capacity by increasing heat sink size has been subjected to its material certainly
The restriction of the body heat radiation limit, there is also heatsink weight weight simultaneously, and thermal resistance is big, the problem that radiating efficiency is low.On market the most favourable
With graphite heat radiation fin heat radiation, but, require time for it is known that heat rejects heat to air from graphite heat radiation fin, when heat mistake
Time big, heat radiation can be caused equally very slow, cause the product temperature on substrate to raise, to this end, we design one, to have graphite scattered
The power electronics radiator of backing.
