The heat dissipation principle of the cooling fan is to accelerate the circulation of hot and cold air, so that the cold air enters and the hot air flows away. If the air outlet is small and not smooth, it will cause the hot air to flow out and the cold air to flow in, or say There is less cold air coming in, which will have a great impact on the cooling fan
There is a simple test test. A customer brought an air purifier to our company to measure the air volume of the cooling fan inside. The air purifier was installed on the other end with a leaky net and leaked air, so the air would circulate. It is very hindering. The final result is that the air volume of the cooling fan is more than twice that of the air purifier. In other words, when installed on an air purifier, the exhaust volume of the cooling fan is much smaller
Therefore, designing a smooth air duct for the cooling fan is very helpful for heat dissipation. On the contrary, if the air outlet is not smooth, blindly increase the speed to increase the air volume of the cooling fan itself, but it has very little effect on the heat dissipation effect. Maybe the cost is higher
Does the unobstructed air outlet affect the cooling fan?
