"Micro Cooling Fan" high-power devices 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, "Micro Cooling Fan" optimization results are accurate, and intuitive. Correct and reasonable installation can guarantee good cooling products to play its role to enhance the overall product reliability. We know that: "Micro Cooling Fan" cooling products primarily to ensure that the device during installation and radiator have a good, full surface contact between the device and ---- the contact thermal resistance as low as possible.
