How does the high-power cell phone shield dissipate heat?

  • 2022/05/26

High power cell phone shield is easy to generate heat during long-term use.. If it is not dissipated in time, it is easy to reduce the shielding effect and safety problems of mobile phone. Then many problems of redesigning the shielded radiator of cell phone shield need to be taken into account.



Among the conventional metal materials, aluminum is the first choice for heat dissipation because of its lightness, firmness, fast heat dissipation and moderate price. If the equipment works for 24 hours for a long time, the heat of the machine is very high. In a certain narrow space, the heat cannot be dissipated. Some equipment work in a high temperature environment, and there is temperature when the equipment is started, so the danger can be imagined.


The sma-818k200 high-power cell phone shield by Nanjing Baikang Electromechanical Technology Co., Ltd. shields the super thick radiating teeth on the base of the super large body, which gives the machine enough radiating area. On the contact surface of the power amplifier that is easy to generate heat, the thickened and red copper design is adopted. The copper strip can quickly absorb heat, and then accelerate the absorption of heat through aluminum alloy. After transmission, after contacting with the air, the heat has already dissipated into invisibility. Multiple groups of super cooling fans on both sides of the fuselage give full play to the principle of air convection. Automatically detect the temperature through the thermistor, and then start the fan. When the heat is low, the wind speed is slow, and when the heat is high, the wind speed is fast. The heat generated by the work of internal components is blown to the outside, and the low-temperature air around is supplemented to form convection and play a circulating role. The combination of inside and outside forms an ideal heat dissipation mode. The heat dissipation silicone oil is applied between the module and the radiator to form a perfect fit, which can ensure the best working state in a high temperature environment. It can be turned on for a long time and has stable performance.
