When using the laptop, may find that the power adapter is heated during use, especially when charging and using in the hot summer. In fact, this is a normal phenomenon because It consumes energy in the process of converting voltage, and part of it is converted into heat energy and emitted. As all know, energy conversion will lose the conversion efficiency of the existing European and American six-level energy efficiency standard power adapter Between 70%6-90%. For example, in the 12V10A power adapter, the six-level energy efficiency standard efficiency requirement is less than or equal to 88%, the conversion efficiency of the power adapter is currently difficult to find a High-Efficiency Universal Self Balancing Scooter Adapter is in progress.
Of course, it is also not excluded that some poor quality power adapters generate heat due to design defects, or use poor-quality components, or circuit designs do not meet safety standards at all, because these products do not meet the design temperature rise or other parameters. Safety standards are completely incommensurable with real power supplies. Therefore, consumers are advised to choose conventional power products. For normal power adapters, look first at the nameplate, which will have a safety flag, some will also have a certificate number with manufacturer information, or a factory abbreviation or full name, or LOGO, in the domestic circulation and use process, will require 3C certification, so in the process of purchase must pay attention to this information, to avoid the purchase of inferior copycat products.
In addition to not using a poor quality power adapter, should also take care to use the original power adapter whenever possible. Even if replaced, a power adapter corresponding to the output voltage of the product used must be selected. Suppose the router’s power adapter is broken and has been used before. This is a 9V1A power adapter, so you can only replace the 9V power adapter, otherwise, the router will not work or even burn out. This is about voltage, and special care must be taken to match the output current of the power adapter. Not less than the original output current, otherwise the power adapter will overload, if overloaded, the power will become hot, or the protection will be no output or even damaged.
After paying attention to the above points, need to consider environmental factors. The weather is getting hot. Even if the original power adapter is lower than the temperature, the temperature of the casing will increase. Therefore, the power adapter cannot be used during use. Placed in direct sunlight or in a hot closed environment, it should be placed in a cool and ventilated place. Otherwise, not only the heat of the power adapter will not be dissipated, but also some heat will be absorbed. In the hot summer, can put the power adapter on its side. Increase the contact area between the power adapter and the air, so that the heat of the adapter can be better dissipated. In order to obtain a better heat dissipation effect, can also pad a narrow plastic block or metal block between the power adapter and the desktop, In order to increase the air convection speed around the adapter, speed up the heat dissipation of the adapter. Do not place objects on the power adapter, which will cause heat dissipation. If possible, add a fan next to the power adapter to dissipate heat.
