Dongguan Golden Eagle's wireless charging coils helped customers solve the overheating problem and successfully secured a large order.

Wireless charging coils transform the original fixed power supply into a electromagnetic field. Through the wireless transmission characteristic of this field, the receiving end converts the sympathetic electromagnetic field back into electric current for charging. When the sympathetic electromagnetic field encounters metal objects, it generates eddy currents within the metal. These eddy currents cause heat in the metal, leading to issues such as low charging efficiency and excessive heat generation in the charging coils.

Dongguan Golden Eagle Coils has been dedicated to researching how to improve the charging efficiency of coils and ensure product safety. Through extensive testing, Dongguan Golden Eagle Coils applied magnetic shielding sheets to both the transmitting and receiving ends of the charging coils. By utilizing electron scattering caused by the thermal motion of functional component lattice electric fields and the interaction between electrons, these sheets absorb electromagnetic wave energy, rapidly enhancing the inductance value of the coils, reducing heat generation from current, and maximizing the conversion of electromagnetic energy into electrical energy.

Mr. Chen works for a company specializing in mobile phone chargers, where he has served as a purchaser for over a decade, demonstrating deep familiarity with the company’s operations and adept problem-solving skills. Recently, the company planned to expand into wireless charging business. Although they negotiated with several potential clients, the samples sent were all returned. Customers complained that the products were too bulky with no unique selling points, had slow charging speeds, and generated excessive heat during charging.

With the impending loss of orders, the entire company was anxious. To solve the problem, they held three meetings a day and conducted research every two days. Learning that Dongguan Golden Eagle Electronics, their supplier of inductance coils, was also developing wireless charging coils, Mr. Chen invited them to participate in the development of wireless chargers. After evaluating the company’s products, Dongguan Golden Eagle’s technical team identified design flaws in the charging coils and poor-quality magnetic shielding sheets.

Dongguan Golden Eagle Coils redesigned the wireless charging coils according to the charger’s structural and performance requirements. After three days of trial installation and testing, the charging speed increased by 10%, and during continuous charging tests over 24 hours, the maximum temperature rise of the charger was only 10°C. The newly designed coils were also adjusted in shape to match the product’s new design, making it smaller and more aesthetically pleasing.

The successful development of this project helped Mr. Chen’s company immediately secure numerous orders, and Dongguan Golden Eagle became their largest coil supplier.
