Fans are our daily necessities, especially one of the must-haves in summer. But do you know about the miniature car cooling fan? Do you know what is the main factor that affects the miniature car cooling fan? Next, let the editor of Tongchi tell you! u003cbru003e u003cbru003e u003cbru003e    The air volume and air pressure of the miniature cooling car fan are the main factors that determine the heat dissipation efficiency. After the general fan size is determined, the key requirements for the characteristics of the car cooling fan are air volume and air pressure, not the fan speed. Usually people will misunderstand this Focus. u003cbru003e u003cbru003e u003cbru003e    Use the fan speed of manufacturer A as 2400RPM, as long as the fan of manufacturer B is also 2400RPM, it is completely wrong to do so. For example, the 4028 fan speed of manufacturer A is 8000RPM, the air volume is 30CFM, and the air pressure is 15mmHO2 u003cbru003e, the rated current is 0.16A, and the noise is 30dB; then the 4028 fan speed of manufacturer B is 7500RPM, the air volume is 32CFM, and the wind pressure is 15.6mmHO2 u003cbru003e, the rated current is 0.14A, and the noise is 30dB; from the numerical point of view, the parameters of manufacturer B will be better than those of manufacturer A, and manufacturer B’s 7500RPM The fan of u003cbru003e can completely substitute with the 8000RPM fan of manufacturer A (other quality is the same under the previous title), so we choose the fan not to look at the specification speed, but the air volume u0026 pressure. u003cbru003e u003cbru003e u003cbru003e    The air volume of the mini car cooling fan: The air volume is the volume of air per minute and the volume of air sent or sucked in [unit M3/min (ft3/min), how many cubic meters per minute (cubic feet)]. (CFM or CMM) u003cbru003e u003cbru003e u003cbru003e    The wind pressure of the mini car cooling fan: The wind pressure is the pressure that the fan needs to generate when the fan overcomes the resistance to supply air, and it is divided into static pressure and dynamic pressure. u003cbru003e u003cbru003e u003cbru003e    Static pressure refers to the pressure measured parallel to the direction of the gas flow. Dynamic pressure is the process by which the kinetic energy required for gas flow is converted into pressure [ u003cbru003eUnit: mm/H2O(inch/H2O), how many millimeters (inches) of wind pressure water column].
