How does the photovoltaic inverter dissipate heat?

       The photovoltaic inverter is the core equipment of the power station, but in fact the inverter is not only an inverter, but a safety steward of the photovoltaic power station. The inverter is also responsible for the detection and protection of the photovoltaic policy and the grid, and protection of the external environment. System-level functions such as human-computer interaction. Its life is directly related to the normal working state of the entire power station, and the heat dissipation problem of the photovoltaic inverter is an important factor that affects the components, and the power loss caused by the heat generated by the inverter is unavoidable. So how do we dissipate heat from the photovoltaic inverter? 

       The components in the inverter have their rated operating temperature. If the inverter has poor heat dissipation performance, as the inverter continues to work, the components will not be able to transfer heat to the outside world, and their temperature will become higher and higher. Too high temperature will reduce the performance and life of components. In order to keep the working temperature of the internal components of the inverter within the rated temperature range and ensure their efficiency and service life, thermally conductive materials are required to transfer the internal heat of the inverter.  

       The main heating components in the inverter are: switching tubes (IGBT, MOSFET), magnetic core components (inductors, transformers), etc. Therefore, in order to ensure that the components can work at the rated temperature, the heat dissipation capability of the system is very important. The inverter usually uses natural heat dissipation, which must ensure sufficient contact between the heating element and the radiator to better transfer heat, and thermal interface materials are essential. Usually use thermal conductive silicone grease, thermal resistance is small, thermal conductivity is better; but power devices also need to consider the issue of insulation, you need to use a thermal conductive sheet with insulating properties, high breakdown voltage, base material, tear-resistant materials are more suitable Require.
