During the operation of photovoltaic inverters, various components have a rated working temperature. If the selected photovoltaic inverter heat sink has poor heat dissipation performance, the heat generated by the components in the inverter will continue to accumulate inside the cavity. If the temperature is too high, it will to some extent reduce the performance and lifespan of the components. The machine is particularly prone to malfunctions. Therefore, We must have a clear understanding of the heat dissipation method of photovoltaic inverter heat sinks and master certain selection methods to ensure the performance and service life of the product.
The heat dissipation method of photovoltaic inverter heat sink
The heat dissipation technologies used in photovoltaic inverter heat sinks mainly include liquid cooling, forced air cooling, and natural cooling, and their main application forms are natural cooling and forced air cooling. The natural heat dissipation method refers to the use of no external auxiliary energy to allow local heating devices to dissipate heat to the surrounding environment, thereby achieving temperature control. This method is suitable for low-power devices that do not require high temperature control requirements; The forced air cooling cooling method refers to the use of fans and other means to take away the heat emitted by the device. This type of heat sink material generally uses aluminum or copper aluminum composite materials.
The selection method of photovoltaic inverter heat sink
Inverters generate heat during operation, and power loss is unavoidable. Just like a 5kW inverter, the normal system heat loss is about 75-125W, which affects the power generation to a certain extent. To solve this problem very well, it is necessary to pay attention to it when selecting. It is recommended that you choose high-quality and professional photovoltaic inverter heat sink manufacturers and cooperate with them, Customizing photovoltaic inverter heat sinks suitable for personal use can greatly reduce heat dissipation losses.
