【 Ac fan 】 About the interpretation of the wind.
wind pressure and air volume are two relative concepts. In general, under the manufacturer's cost considerations, to design the fan air volume is big, have to sacrifice some wind pressure. If the fan can bring a lot of air flow, but the wind pressure is small, the wind is less than the bottom of the radiator ( That is why some fan speed is high, volume is very big, but it is the reason why cooling effect is not good) , on the contrary, wind pressure is often means that the air volume is small, there is not enough air and heat sink for heat exchange, also causes the cooling effect is not good.
