This issue is crucial, and the core conclusion is that through the system integration design of "structural layout optimization+heat dissipation scheme upgrade+thermal management collaboration", the heat dissipation efficiency of solar inverters can be significantly improved.
1. Layout optimization of core heating components
The core heat sources such as power modules and transformers are arranged in a dispersed manner to avoid concentrated heat accumulation.
The heat source is directly connected to the heat dissipation structure (such as heat sinks, fans) to shorten the heat conduction path.
Reasonably plan the internal air ducts to ensure that cold air can directly reach the heat source and hot air can be smoothly discharged without any dead corners.
2. Integrated upgrade of heat dissipation scheme
Adopting a combination design of "passive heat dissipation+active heat dissipation", natural heat dissipation is achieved through heat dissipation fins at low loads, and the fan or liquid cooling system is automatically started at high loads.
The integrated design of the heat dissipation structure and inverter casing expands the heat dissipation area while reducing thermal resistance.
Select high thermal conductivity materials (such as aluminum alloy and heat pipes), and fill thermal grease between the heat source and the heat dissipation structure to improve thermal conductivity efficiency.
3. Collaborative design of thermal management and electrical systems
Optimize circuit topology, reduce switch losses and conduction losses, and minimize heat generation from the source.
Integrated temperature monitoring module, providing real-time feedback on the temperature of core components, dynamically adjusting the power of the cooling system to avoid excessive or insufficient heat dissipation.
Standardize the installation gap between electrical components and heat dissipation parts to ensure insulation performance without affecting heat transfer.
