Power "220V Cooling Fan" device to optimize the main radiator for heat sink substrate thickness, tooth thickness, spacing, height, surface treatment and other parameters to optimize the design. Computer simulation technology continues to progress, we can rely on the electronic thermal simulation software to optimize radiator, optimization and accurate, and intuitive. Correct and reasonable installation "220V Cooling Fan" can guarantee good cooling products to play its role to enhance the overall product reliability. We know: cooling products primarily to ensure that the device during installation and radiator have a good, full surface contact ---- "220V Cooling Fan" to make contact between the device and the heat sink thermal resistance as low as possible.
