What about AC Cooling Fan?lLet's talk about it.
AC, referred to as AC. also known as " alternating current", referred to as "exchange." Generally refers to the size and direction of the cyclical changes over time voltage or current. Its most basic form is a sinusoidal current.Hippolyte Pixii created the first AC motor based on the principle of Michael Faraday by Michael Faraday in 1832
Frame:Aluminum Alloy
Impeller:PBT+30%GF
Lead Wire:AWG#22 UL 1007 (Optional)
Motor:Shaded Pole Induction Motor
Insulation:CLASS B
It can be used for ventilating or enhancing the heat dissipation in metallurgy, chemical industry, light industry, foodstuff, medical equipment, machinery equipment and civil buildings, etc. If the case is removed, it can also be used as a free fan, The pipes are installed in series in order to increase the pressure in the pipes.
cooling fan features:
Small cooling fans: low power consumption, fast cooling, low noise, energy saving and environmental protection. Because of its small size and more extensive use.
Large-scale cooling fan has a simple structure, solid and reliable, low noise, air volume, wide selection of features and so on.

Therefore, following the vigorous development of the access control system in recent years, the access control system has entered a new development mode. During the period when the biometric technology is so mature, the biometric access control system will be more and more, including the fingerprint access control system, the iris access control system, and the face. Identify access control systems and more. They not only have their own strengths in terms of safety, convenience, and manageability, but most importantly, they are more in line with the general trend of energy conservation and environmental protection. It is understood that biometrics have high requirements for the environment and users. For example, the fingerprint can not be scratched, the eyes can not be red and swollen, the face can not be injured, and even the amount of the beard will affect the accuracy and sensitivity of the recognizer. At the same time, the installation height and the user's height are not well adjusted. Therefore, if we insist on developing biometrics on the access control system, we must reflect the energy saving advantages to the extreme. Therefore, the development of biometrics is of great significance for energy conservation and environmental protection. How to combine the advantages of biometric energy conservation with the advantages of traditional access control cards, This is the problem that security access control companies need to ponder. In my opinion, the popularity of biometric access control systems lacks technological advancement and state support. Through the support of state support funds, reduce technology costs, and thus promote technology integration and product promotion.
It can be seen that energy conservation and environmental protection are not problems that they have just said. It is necessary to bring out the biometric access control system technology as soon as possible. Manufacturers become subjective and grasp the lifeblood of development trends. Energy conservation and environmental protection should be the first priority.
[ Huaqiang Security Network News ] The application of the access control system in life has been very extensive. Through extensive investigations, it is found that two-thirds of the citizens will basically hold more than three cards, including access control cards, bank cards, and transportation cards. basic. However, the current energy conservation and environmental protection advocates that the access control system has entered a trough. Everyone has three cards or more. So how much card share does China have over 100 million people? The circulation of a wide variety of cards is unpredictable. According to the combination of energy-saving and environmental protection features, if the card is strongly promoted, it can not only be easily carried and used, but also greatly reduce the number of other cards. To a certain extent, this is alleviating the waste of card resources, and it also meets the concept of energy conservation and environmental protection.
