Inverters are also called power regulators. The process of converting DC power into AC power is called invert. The circuit that can realize the inverting function is called an inverter circuit. A device that can realize the inverting process is called an inverting device or inverter. In a solar energy generation system, the inverter efficiency is an important factor that determines the solar cell capacity and the storage battery capacity. The breakdown of PV inverter will cause the PV system to shut down and this directly leads to the loss of power generation. Therefore, high reliability is an important technical indicator for PV inverters.
Heat sink parameters:
(The temperature difference between both ends of the heat pipe is 5.7℃, which meets the practical criteria for heat pipes.)
(The temperature difference between both ends of the heat pipe is 9℃, which is slightly higher than the real scenario. The actual performance of the heat pipes will be better than those configured in this analysis.)
(The actual air temperature entering the heat sink is ~57.1?C and the maximum temperature at the heat sink bottom is 85.1?C with a temperature difference of 28?C according to the theoretical analysis.)
(The temperature difference between both ends of the heat pipe is 9℃, which is slightly higher than the real scenario. The actual performance of the heat pipes will be better than those configured in this analysis.)
