Due to the maturity of the vacuum cleaner industry, almost every household now has a vacuum cleaner. However, there are more and more brands and more and more functions. Your friends have made a lot of mistakes when choosing a vacuum cleaner. Many people don't know how to choose. AOQUN has some suggestions for choosing a vacuum cleaner: 1. Vacuum cleaners are mainly divided into three types: horizontal, vertical and hand-held. Because horizontal vacuum cleaners were launched earlier, they are larger in size, consume more power, and are more expensive; although vertical vacuum cleaners consume There is not much electricity, but there will be some insufficient suction power; hand-held vacuum cleaners are small in size, and the suction power and power consumption are both moderate, so this type of vacuum cleaner is used more at home. 2. There are two types of vacuum cleaners: wired and wireless. Wired vacuum cleaners produced in the early years were more popular at the time. However, with the continuous development and innovation of vacuum cleaner technology, wireless vacuum cleaners have gradually entered people’s field of vision and have basically replaced them now. In addition, the wired vacuum cleaner is located in a place as high as the ceiling, and the wired vacuum cleaner cannot be cleaned, so it is a good choice to buy a wireless vacuum cleaner now. 3. The dust collection capacity is also very important. The amount of dust collection is related to the motor. Currently, the motors on the market are divided into ordinary brush motors and digital brushless motors. Brushless motors have high suction power and low energy consumption, which is relatively more. Suitable for home use. 4. For wireless vacuum cleaners, it is very embarrassing to find that there is no electricity in the middle of the cleaning work. Therefore, when buying a wireless vacuum cleaner, pay attention to the battery life, which depends on the battery type and capacity of the vacuum cleaner. Most wireless vacuum cleaner batteries are divided into nickel-cadmium batteries, nickel-metal hydride batteries, and lithium batteries. Different types of battery life and life are different, but because the life and safety of lithium batteries are the best, so most of the current home appliances Lithium battery is the first choice for power supply. 5. When buying a vacuum cleaner, pay attention to its mite removal function. Bed sheets are a good environment for nourishing mites. Living under the damage of mites for a long time will not only affect the development of children, but also cause our more serious skin allergies, scabies and other problems. It is very important to buy a vacuum cleaner with the function of removing mites. 6. At the same time, when the vacuum cleaner is working, there will always be more or less noise problems. If it is a qualified vacuum cleaner, it will have the function of eliminating noise, mainly by adopting a noise reduction design on the air duct of the va...

Even if there is a complete air conditioning system inside the cabinet, there are many devices in the data center. In fact, the temperature distribution in the cabinet is uneven. Even if the current data center is equipped with ventilation ducts, the front of the cabinet is the air inlet and the rear is the air outlet, which can immediately take away the heat. However, because the heating power of various devices is different, if high-power devices are installed in some locations, local overheating of the computer room is prone to occur, which affects the safe operation of the data center, and may even cause hardware damage and individual equipment. A series of problems such as shutdown due to high temperature appeared. Therefore, it is necessary to control the temperature range in the data center computer room to remove or reduce local hot spots. In order to improve the operating environment of IT equipment, ensure the long-term safe and stable operation of the data center, remove local hotspots, and reduce the excessive temperature of the local cabinets, some measures to deal with the hotspots of the data center are discussed below. There are 7 factors that cause hot spots in the local location of the data center: 1. The free U position gap in the cabinet causes the temperature in the cabinet to rise. 2. The gap between adjacent cabinets in the same row causes the temperature inside the cabinet to rise. 3. The temperature inside the cabinet rises between the bottom of the cabinet and the electrostatic floor. 4. The mismatch between the air supply volume of the perforated floor corresponding to a single cabinet and the air volume required by the IT equipment in the cabinet causes the temperature in the cabinet to rise. 5. The matching of the density of the cabinet orifice and the air volume of the equipment causes the temperature in the cabinet to rise 6. Inappropriate input cooling capacity and heat load cause the temperature in the cabinet to rise. 7. The data center has been used for longer and longer. Some of the old equipment in the cabinet and the hot air generated by the heating equipment itself cannot be efficiently discharged, which causes eddy currents in the cabinet, resulting in high temperature and high pressure in the cabinet, resulting in high local temperature. In the past, most of the methods for solving local hot spots were to increase the cooling capacity of the entire room, which would only increase energy consumption, and the local hot spots have not been completely eliminated. In addition, the point-to-point active refrigeration method is added, which is rack-mounted precision air supply air conditioner. This method has a long layout period, large investment, and layout is also very difficult. Based on several years of experience, and related standards and best tests at home and abroad, there are 7 points about how to solve local hot spots: 1. The manual air valve and the directional ventilation plate are the cold air diver...

Guangzhou AOQUN Brush Industry CO., Ltd. Has more than 10 years ‘experiences of flame retardant server rack brush strip design and manufacture. The 1U/2U server rack brush strip is used widely on the server or KVM plug inside the rack cabinet. It provides a professional server rack airflow management solution. The server cabinets are placed densely in the data center. The inner servers run for a whole day and produce heat continuously. Thus the servers will be easily damaged by overheated. So we need the air condition to keep the dater center cool. As there are gap/hole on the cabinets, the airflow leak from it. AOQUN server rack brush strip seal the gap/hold of the server cabinet, keep the cool air inside the server cabinet and prevent the heat exchange between the server cabinet. Therefore, it provides a steady cooling environment for the server running and extend the service life of the server. Meanwhile, the server rack brush strip hides the messy cables, make sure the cables can go through the server rack brush strip but not affect the appearance of the dater center. AOQUN server rack brush strip is standard for 1U/2U and even 3U server, it complies with the EIA-310-E plug standard. There are many kinds of H Type easy-to-install aluminum profile for your choice. In addition, we have independently developed the flame retardant filament which authorized by UL94 certificate and reached the highest UL94 V-0 flame retardant standard. (We have the third party test reports), and also passed the six heavy metal testing of ROHS.
