Radiator design of micro heat pipe array inverter in high altitude area

This paper focuses on the core components of photovoltaic inverter, which will produce a lot of heat during operation. This part of heat will heat the power device die integrated in the inverter, increase the junction temperature and reduce the reliability. By using the micro heat pipe array technology and coupling the phase change heat dissipation on the basis of the physical heat dissipation of the existing inverter radiator, the micro heat pipe array inverter radiator in high altitude area is studied.
