OEM Copper Heatsink for Electrical Power Supply COB Heat Sink

Basic introduction:
Look at the shape of the fin radiator bent through a thin aluminum plate, it looks like the bellows of an accordion; Each blade of the vortex radiator is tilted in one direction to facilitate air circulation. The heat dissipation efficiency of these two products is relatively strong.
Look at the material aluminum extrusion profile of the radiator price is the lowest, but the heat dissipation effect is not good; Gold, silver, copper radiators have good cooling effect, but the cost is high and the weight is large. The most cost-effective radiator is made of aluminum alloy.
Look at the area radiator is through the form of convection heat dissipation, the larger the surface area, the better the heat dissipation effect. When selecting a radiator, attention should also be paid to the heat dissipation area of the radiator.
Other: When choosing an aluminum radiator, pay attention to the bottom of the radiator can not be too thick, because the thermal conductivity of aluminum is not good, too thick will affect the transfer of heat; In addition, the diversion groove on the surface of the radiator should be dense, which can ensure that the radiator can have a larger contact area with the air, thereby enhancing the heat dissipation effect. It is not recommended to buy a silent passive laptop radiator, because the bottom pad design of the laptop has a very small contact area with the radiator, and it is difficult to conduct heat from the body to the radiator.
