How to accurately calculate the speed of the cooling fan required by the product
When a new product is developed, the speed of the cooling fan is not known, so I can only estimate according to the specifications of the cooling fan, choose one of them, after a few days of sampling, but often the samples that come back are unqualified , And then I made the second and third attempts. The cooling fan samples were taken several times before they were barely qualified. The cooling fan manufacturers share a simple method here to accurately calculate the speed of the cooling fan required by the customer’s products. The first step ，According to the shape and voltage of the cooling fan, choose a sample with medium speed and let the customer install it in the product to measure the heat dissipation and ventilation. If it is qualified in one step, it is best. If it is not suitable, the second step, if the customer feels the wind If it is too small, please connect an external power supply to the fan. The voltage last week, the voltage rises, the speed becomes faster, and the air volume becomes larger. Adjust the air volume to the customer's desired air volume. Write down the voltage at this time and include the fan samples. Send it back to the cooling fan manufacturer, we will also adjust to the voltage value recorded at the time, test the speed, and then make the last sample. The air volume and speed are measured by the customer, so it must be the most accurate. We tailor There will be no discrepancies in customization. Therefore, as long as the shape mold confirmed by the customer is OK, the accurate speed of the cooling fan that the customer wants can be obtained through two steps.
