Wind speed:
Wind speed refers to the speed at which air moves relative to a fixed place on the earth. Common units are meters per second, 1 meter per second = 3.6 kilometers per hour. Wind speed can only be graded if there is no grade, and wind speed is the basis for wind grading. Generally speaking, the greater the wind speed, the higher the wind level and the more destructive the wind is. Wind speed is one of the main parameters in climatology research, and the measurement of atmospheric travel plays an important role in global climate change research, aerospace industry and military application.
Air volume:
Air volume refers to the total amount of air sent or inhaled by air-cooled radiator fans per minute. If calculated in cubic feet, the unit is CFM；; ; If calculated in cubic meters, it is CMM, and the common air volume unit of radiator products is CFM.
Under the condition of the same radiator material, air volume is the most important index to measure the heat dissipation capacity of air-cooled radiator. Obviously, the greater the air volume, the higher the heat dissipation capacity of the radiator. This is because the heat capacity of air is fixed, and the larger the air volume, the more air can take away more heat per unit time. Of course, the heat dissipation effect is related to the airflow mode under the same air volume.
