2. the space structure utilization rate is low: in order to improve the heat conduction capability, the structural space of the radiating fins and the heat conduction copper tubes is required to be increased in the inner part and the outer part of the fluorescent wheel cavity, so that the space structure of the whole projector is forced to be increased;
3. the refrigeration power consumption is big: the temperature control circuit and the power supply driving circuit of the TEC are additionally added, so that the refrigeration power consumption is high, heat is generated in the optical machine of the projector, and the heat dissipation burden is increased.
