What does 22000 air volume mean?
Every hour, 20000 cubic meters of air are sent out or inhaled. The air volume refers to the total volume of air sent out or sucked in by the air-cooled radiator fan per minute. If calculated in cubic feet, the unit is CFM; If calculated in cubic meters, it is CMM, and the air volume unit commonly used in radiator products is CFM. CMH stands for Cube Meter Hour (m/h), which means cubic meters per hour. The conversion is 1L/S=3.6CMH, and 900 is 250 liters/second, which is 0.25 cubic meters/second. When the material of the heat sink is the same, air volume is the most important indicator to measure the heat dissipation capacity of an air-cooled radiator. Obviously, the larger the airflow, the higher the heat dissipation capacity of the radiator. This is because the heat capacity of air is constant, and a larger air volume means that more air can carry away more heat per unit time. Of course, the heat dissipation effect is related to the flow of wind under the same air volume.
3. Unit of air volume
The unit of air volume is cubic meters per minute.
. The air volume refers to the total volume of air sent out or sucked in by the air-cooled radiator fan per minute. If calculated in cubic feet, the unit is CFM; If calculated in cubic meters, it is CMM, and the air volume unit commonly used in radiator products is CFM. The influencing factors of air volume: When the material of the heat sink is the same, air volume is the most important indicator to measure the heat dissipation capacity of an air-cooled radiator. Obviously, the larger the airflow, the higher the heat dissipation capacity of the radiator. This is because the heat capacity of air is constant, and a larger air volume means that more air can carry away more heat per unit time. Of course, the heat dissipation effect is related to the flow of wind under the same air volume. The difference in heat distribution is large, and the generated wind is large or small. The higher the heat, the lower the density, and the higher the density where the heat is relatively small, this is thermal expansion and contraction. Airflow will flow from areas with higher density to areas with lower density. If there is a large difference in density, the airflow will be larger, which means the wind will be stronger.
