Technical Field

The utility model relates to a heat radiation structure, in particular to high-accuracy subsides of metal film dress resistance heat radiation structure.

Background

Resistance is a physical quantity that indicates, in physics, the magnitude of the current blocking effect of a conductor. The higher the resistance of the conductor, the greater the effect of the conductor on the current. Different conductors generally have different resistances, which is a property of the conductor itself. The resistance will cause a change in electron current flux, the smaller the resistance, the greater the electron current flux and vice versa. While superconductors have no resistance.

The resistance can give off the heat at the during operation, and the high temperature resistance can lead to the fact the influence to electron flow, but current resistance does not possess the heat radiation structure, mostly through self-cooling, and the radiating efficiency is low.
