Inverter is also called power regulator. The process of converting DC power into AC power is called inversion. The circuit that completes the inverting function is called inverting circuit. The device that realizes the inverting process is called inverting equipment or inverter. In solar power generation system, the efficiency of inverters is an important factor to determine the capacity of solar cells and storage batteries. The failure of photovoltaic inverters will lead to the shutdown of photovoltaic system, which will directly cause the loss of power generation. Therefore, high reliability is an important technical index of photovoltaic inverters.

The good heat dissipation of photovoltaic inverters is an important condition to ensure its high reliability. Therefore, at the beginning of the design of the inverters, the heat dissipation simulation test has become the first consideration of photovoltaic inverters manufacturers. Tongyu Thermal Power is a professional high-power heat sink plant in China. It has first-class thermal design and development team, reliable thermal simulation and thermal testing capabilities. It has carried out technical cooperation on heat dissipation of inverters with many domestic and foreign photovoltaic inverters manufacturers to provide professional technical support for heat dissipation.

According to the provisions of the State Grid, the proportion of distributed generation such as photovoltaic and wind power should not exceed 10% of the power grid, and more than 10% of the grid will be added to the energy storage system. Because photovoltaic system and wind power system do not use energy storage system in grid-connected power generation, there will be some adverse effects on the grid. If the scale of wind energy and photovoltaic power system continues to expand and the proportion of photovoltaic power in the system continues to increase, these effects can not be ignored. Through the analysis of the characteristics of photovoltaic power generation, it can be seen that the impact of photovoltaic power generation system on the grid is mainly caused by the instability of photovoltaic power supply. In order to make the grid safer, stable and economic operation, it is generally required to install energy storage system. Therefore, the demand for energy storage system has increased in recent years.

The stable operation of energy storage system is related to the safety and stability of power grid, so major energy storage system manufacturers attach importance to its quality, and among the factors affecting the stability of energy storage system, heat dissipation performance is undoubtedly the most important. Tongyu Thermal Energy focuses on high-power heat dissipation, and has rich experience in the research and development and manufacture of radiators for energy storage systems. Tongyu Thermal Management Engineer can provide heat dissipation solutions at the beginning of the design of energy storage systems, and also can optimize the heat dissipation performance of energy storage systems.

Power batteries are the batteries that provide power for machines as power sources, generally referring to the batteries that provide power for new energy vehicles such as electric vehicles, electric trains and so on. New energy vehicles refer to those vehicles with advanced technology in power control and drive, which are formed by using unconventional vehicle fuel as power source and integrating advanced technology in vehicle power control and drive. New energy vehicles are regarded as promising because of their energy-saving and environmental protection characteristics and are strongly supported by national policies to implement the State Council's policy on fostering strategic emerging products. Deployment and requirements for energy conservation and emission reduction should be strengthened. The central government should allocate special funds to support the pilot project of subsidies for private purchases of new energy vehicles.

New energy vehicles are mainly composed of battery drive system, motor system, electronic control system and assembly. Among them, motor, electronic control and assembly are basically the same as traditional automobiles. The biggest difference lies in the difference of power sources. Power battery pack is an important power source for new energy automobiles. The majority of new energy automobile enterprises have increased their research and development on power battery pack to solve the technical bottleneck of high cost, weak battery endurance and low charging speed of power battery pack. In addition, technical cooperation with heat dissipation enterprises such as thermal energy is launched to improve the performance of power battery packs.
