The main heat sources for security protection:
1. The heat generated by the power PCB board;
2. The heat generated by the image processing module;
3. The heat generated by the power transformer;
4. Heat generated by CPU&graphics memory chips;

Heat dissipation principle:
Transfer the heat emitted by components to the heat dissipation component or metal shell through the principle of heat conduction; By the principle of heat dissipation through air convection, heat is taken away; Reduce the temperature of the heating element to extend its service life.
