[0002] With the booming development of the photovoltaic market, high-power photovoltaic inverter outdoor units have emerged to adapt to various complex and changeable outdoor environments, such as salt spray, dust, rain, condensation and other extreme conditions. In these special use occasions, the low-protection components inside the inverter, such as inverter power unit, DC circuit breaker, bus capacitor, AC contactor, AC circuit breaker, etc., how to achieve reliable heat dissipation under high protection conditions has become an urgent problem to be solved.
