The cell phone signal jammer is a high-power, high-current device, and the cell phone signal jammer will generate heat when it works. If it is not dissipated in time, it will affect the normal operation of the machine at light level, and endanger personal safety at worst. Most electronic products or other power devices of the same type take the thermal conductivity of the machine very seriously.
So, how to solve the heat dissipation problem of high-power mobile phone signal jammers?
Among the commonly used metal materials, silver has the best thermal conductivity, followed by copper and aluminum; but silver is expensive and seldom used for heat dissipation; although copper has good thermal conductivity, it does not dissipate heat quickly, which may cause cell phone signal jammers for 24 hours Uninterrupted work, the heat of the machine cannot be dissipated, forming an invisible space heat source in a small space. If you encounter high temperatures in summer, the danger can be imagined.
In contrast, aluminum is the most ideal, it is light and strong, has good thermal conductivity, and dissipates heat quickly; good CPU air-cooled radiators are all made of aluminum alloys. Therefore, many high-power mobile phone signal isolators power amplifier shells are all made of cast aluminum (cast aluminum alloy), and the copper bars quickly conduct heat and heat dissipation through aluminum heat sinks, giving the machine enough heat dissipation area.
Make full use of the principle of air convection inside the shield. The temperature is automatically detected by the thermistor, and then the fan is started. The wind speed is slow when the heat is low, and the wind speed is fast when the heat is high. The heat generated by the operation of the internal components is blown to the outside, supplementing the surrounding low-temperature air, forming convection, and playing the role of circulation; the combination of the inside and the outside forms an ideal heat dissipation method.
