Problems solved by technology

[0003] The circuits of smart projection mobile phones mainly include: radio frequency circuit, voice circuit, processor and memory circuit, projection drive board circuit; power supply and charging circuit, operation and screen display circuit, interface circuit, and other functional circuits, including Bluetooth, antenna, Radio, sensor, vibrator, projection camera circuit; also includes processor, memory, LED light source, mirror, radio frequency chip, radio frequency power amplifier chip, processor chip, power management chip, memory chip, touch screen control chip, projection chip, etc.; When the projection mobile phone is in the working state of projection, the power of the chips on the circuit board and circuit electronic devices is large, and the heat generation is high. Since the back cover of the existing projection mobile phone is generally a sealed structure, which is not conducive to heat dissipation, the heat generation of the projection mobile phone serious;
The body temperature of the projection mobile phone is very high when it is working, and long-term work will cause damage to the chip on the circuit board, and even affect the normal operation of the original projection mobile phone
