Overall temperature distribution of Cast aluminum radiator	Overall temperature distribution of thermal conductive plastic radiator	Remarks: The input power is 50W, and the designed electrothermal conversion rate is 80%.

1. The temperature of the plastic radiator is 5~6°C  higher than that of the aluminum radiator.  The plastic radiator can meet the 50W power.

2. The subsequent optimization of the all-plastic structure according to the aluminum structure makes it more conducive to heat dissipation.
