Mobile phone signal jammers are high-power and high-current devices that generate heat when they are working. If they do not dissipate heat in time, it will affect the normal operation of the machine at the slightest, and endanger personal safety. Most electronic products of the same type or other power devices attach great importance to the thermal conductivity of the machine.
So, how to solve the heat dissipation problem of high-power mobile phone signal jammer?
Among the commonly used metal materials, silver has the best thermal conductivity, followed by copper and aluminum. However, silver is expensive and is rarely used for heat dissipation. Copper has good thermal conductivity, but it does not dissipate quickly. This may cause the mobile phone signal shield to work for 24 hours, and the heat of the machine cannot be dissipated, forming an invisible in a certain small space. Heat source. If it encounters the high temperature in summer, the danger can be imagined.
In contrast, aluminum is the most ideal. It is light and firm, has good heat conduction and fast heat dissipation. Good CPU air-cooled radiators are made of aluminum alloy.
Therefore, the shell of Texin Electronic’s high-power mobile phone signal jammer power amplifier uses all cast aluminum (cast aluminum alloy) materials + copper bars to quickly conduct heat and quickly dissipate heat through the aluminum heat sink, giving the machine enough heat dissipation area.
On the contact surface of the power amplifier, which is most likely to generate heat, the design of thickening and copper is adopted. The copper bar can quickly absorb heat and then accelerate the absorption of heat through the aluminum alloy. After transmission, the heat has long been dissipated invisible after contact with air.
Inside, the principle of air convection is fully utilized. Through the thermistor, the temperature is automatically detected, and then the fan is started. The wind speed is slow when the heat is low, and the wind speed is high when the heat is high. The heat generated by the work of the internal components is blown to the outside, and the surrounding low-temperature air is replenished to form convection and play a circulatory effect. The combination of inside and outside forms an ideal way of heat dissipation.
