1. 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.

2. English materials related to vacuum cleaners

A vacuum cleaner is a device that uses an air pump to create a partial vacuum to suck up dust and dirt, usually from floors. Most homes with carpeted floors in developed countries possess a vacuum cleaner for cleaning. The dirt is collected by a filtering system or a cyclone for later disposal. Introduction TechnologyA vacuum"s suction is caused by a diff

erence in air pressure. A pump reduces the pressure inside the tube. Atmospheric pressure then pushes the air through the carpet and into the tube, and so the dust is literally pushed into the bag.Tests have shown that vacuuming can kill 100% of young fleas and 96% of adult fleas. The technology used ConfigurationsVacuum cleaner configurations: * Upright vacuum cleaners take the form of a cleaning head, onto which a handle and bag are attached. Upright designs usually employ a rotating brush-roll, which removes dirt through a combination of sweeping and vibration. There are two types of upright vacuums; dirty-fan/direct air, or clean-fan/indirect air.The older of the two designs, dirty-fan cleaners have a large impellor (fan) mounted close to the suction opening, through which the dirt passes directly, before being blown into a bag. The motor is often cooled by a separate cooling fan. Due to their large-bladed fans, and comparatively-short air-paths, dirty-air cleaners create a very efficient airflow from a low amount of power, and make great carpet cleaners. Their "above-floor" cleaning power is less efficient, since the airflow is lost when it passes through a long hose.Clean-fan uprights have their motor mounted after the bag. Dust is removed from the airstream by the bag, and usually a filter, before it passes through the fan. The fans are smaller, and are usually a combination of several moving and stationary turbines working in sequence to boost power. The motor is cooled by the airstream passing through it. Clean-air vacuums are good for both carpet and above-floor cleaning, since their suction does not significantly diminish over the distance of a hose, as it does in dirty-fan cleaners. However, their air-pa
