What is the planning process for cooling fans? The planning of the cooling fan first measures the relationship between air volume and wind pressure. It is very difficult to measure the characteristics of airflow. Now, there are two methods to measure static pressure and air volume, one is used for wind tunnel test, and the other is used for double box form. The air volume and static pressure characteristics are measured in the form of a double box. The double-box variable exhaust system draws air to adjust the air density. Opening the nozzle immediately will cause the static pressure and air volume to change instantaneously, and then read each static pressure. The pressure reading on the gauge.
Static pressure is a function of air volume as a function of standard atmosphere and fixed operating voltage and frequency. The static power of a cooling fan is equal to the volume of air multiplied by the static pressure divided by the input electrical energy. Is the cooling fan included in the motor? In the blade and the frame, its power includes the motor power of the motor and the air activity power of the blade and the frame.
All system impedance/system characteristic curves of the cooling fan. When the air moves, the airflow will meet the internal parts of the system in its flow path, and its impedance will restrict the free movement of the air. The change in pressure is the measured static pressure, expressed in inches of water. In order to confirm the cooling power of each fuel tank row, the system planning or manufacturer must not only have the useful fan characteristic curve of the cooling fan to confirm its maximum air volume, but also need to know the wind resistance curve of the system. The parts in the system may cause the wind pressure to drop. This loss changes due to the air volume, the so-called system impedance.
In addition, the intersection of the system operating point of the cooling fan and the characteristic curve of the fan is called the system operating point, which is the best operating point for the cooling fan. At the operating point, the slope of the cooling fan is the smallest, and the rate of change of the system characteristic curve is the smallest. Note that at this time, the static power of the cooling fan (air volume × wind pressure, power consumption) is optimized.
