All you need to use the fan cooling electrical and electronic product design engineers, must determine the cooling air volume required for a particular system, and the required air volume depends on the understanding of system power consumption and whether they can take away enough heat, to prevent the system from overheating. Facts show that, the system of use fixed number of year will be reduced due to the shortage of the cooling system, so the design engineer should also understand that the sales of the system and price, be because the system of the use fixed number of year to the user’s expectations.
To choose the correct ventilation components, must consider the following objectives:
- The best air flow efficiency
- The smallest size
- The noise of the smallest
- The minimum power consumption
- The biggest reliability and service life
- The total costs of the reasonable
