Wireless signal jammers are high-power and high-current devices that generate heat during operation. If they do not dissipate heat in time, it will affect the normal operation of the machine, and seriously endanger personal safety. Most of the similar or other power device electronic products will attach great importance to the heat transfer performance of the machine.
How to solve the heat dissipation problem of the wireless signal jammer?
Among the commonly used metal materials, silver has a higher thermal conductivity j, followed by copper and aluminum. However, silver sheets are expensive and are rarely used for heat dissipation. Although copper has good thermal conductivity, it does not dissipate heat well. This will cause the mobile phone signal screen to work 24 hours a day, and the machine will not dissipate smoothly, forming an invisible heat source in a certain small space. . If you encounter high temperature in summer, the danger can be imagined.
In comparison, aluminum is more ideal. It is light, strong, has good thermal conductivity and fast heat dissipation. Good CPU air-cooled radiators are made of aluminum alloy.
Therefore, the shell of the wireless signal jammer adopts cast aluminum material + copper strip to conduct heat quickly, and quickly dissipates heat through the aluminum sheet, so that the machine has enough heat dissipation area.
And on the power contact surface that easily generates heat, the design of thickening and red copper is adopted. The copper bar can quickly absorb heat and then accelerate the absorption of heat through the aluminum alloy. After heat transfer, the heat has long disappeared after contact with air.
Internally, it is to give full play to the principle of air convection. Automatic temperature measurement, start the fan through the thermistor. 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 combustion engine is blown to the outside, and the surrounding low-temperature air is reinjected into the internal combustion engine to form convection and play a circulatory effect. The inside and outside are combined to form an ideal heat dissipation.
