Wireless charging technology exponential growth is inseparable from this important component. Wireless charging is a device that uses the principle of electromagnetic induction to charge. By placing a coil on each of the transmitting and receiving ends, the transmitting end coil emits an electromagnetic signal to the outside under the action of electric power, and the receiving end coil receives the electromagnetic signal and converts the electromagnetic signal into Current to achieve wireless charging. The wireless charging technology has broken through the shackles of the traditional charging line, and the usage rate is getting higher and higher. The wireless charger has once become an explosive product in the mobile phone charging industry. However, due to the small size, the operating temperature of the internal electronic components needs to be solved, and the thermal pad provides a heat dissipation solution.   For higher efficiency heat dissipation, the bottom of the wireless...

What thermal materials are used in drones?   As technology advances with each passing day, the market demands for Take the Dajiang Elf that everyone knows and loves as an example. Let's take a look at how it solves the heat dissipation problem.   The two cores of the drone are the motor and the ESC (ie the electronic governor). The drones are driven by propellers or turbofans. The power to drive them is from the motor, but the speed and power of the motor are controlled by ESC, so The layout of the drone motor and ESC is often relatively compact. If   Thermally gel   There are many types of thermal gel, which one is suitable for drones? Recommended model : WT5921 series The thermal gel is generally packaged in a syringe. The material itself does not contain a solvent, and has the characteristics of high thermal Waermtimo WT5921 series thermal gel is made of silicone, adding thermal conductive filler and bonding material in a certain proportion, and processed by speci...

Exploring Black Technology-How does VR glasses   Virtual Reality (VR) glasses, or VR headsets, are a new means of human-computer interaction created with the help of computers and the latest sensor technology. VR glasses is a cross-generation product that provides users with an immersive experience in a virtual environment. As panoramic content, content can be raised to a level, and VR will collaborate across fields to promote the development of other industries, such as games, social media,   With the development of VR technology, devices that were originally only concept products have now brought virtual experiences and fun to many gamers.

How does the power battery packs of electric vehicle survive the summer? Electric vehicles are becoming more and more popular among the public, and their core power batteries need to be resistant to high temperature, water, and frost. If the electric car does not work, the first time we should consider is the "core" (battery) problem, so in the hot summer, how to deal with the high temperature? How to dissipate heat of the electric car battery? The operating current of the power battery generates a large amount of heat; and the battery pack under a relatively closed environment, it will lead the battery temperature rise. In addition, the outdoor temperature is usually 35+° C. The battery itself generates a large amount of heat. These conditions cause battery heat dissipation become a particularly important problem. Different heat transfer material will lead different effects of heat dissipation, and there exist advantages and disadvantages of both air and liquid cooling. The ...
