As a high-power and high-current device, the cell phone signal jammer will generate a lot of heat when it is working. If it is not dissipated in time, it will affect the normal operation of the machine, and in serious cases, it will endanger personal safety. Therefore, most power device electronic products attach great importance to the thermal conductivity of the machine. So, how does the high-power mobile phone signal jammer dissipate heat?
Among common metal materials, silver has the best thermal conductivity, followed by copper and aluminum. However, the price of silver is relatively expensive, so it is rarely used for heat dissipation. Although the thermal conductivity of copper is good, the heat dissipation speed is slow. It will form an invisible heat source in a certain narrow space. If you encounter high temperature weather, danger will occur at any time.
After comparison, aluminum is the most ideal heat dissipation material, which is light and hard, has good thermal conductivity, fast heat dissipation, and high-quality CPU air-cooled radiators are mostly made of aluminum alloys.
Therefore, cast aluminum (cast aluminum alloy) materials and copper strips can be used on the power amplifier casing of the high-power mobile phone signal isolator, and the heat dissipation can be quickly dissipated through the aluminum heat sink to provide sufficient heat dissipation area for the machine. Then, on the contact surface of the power amplifier that is most likely to generate heat, the design of thickening and adding red copper is adopted. The copper strip can quickly absorb heat, and then use aluminum alloy to speed up the absorption of heat.
