AI Technical Summary
When the capacity of a conventional oil-immersed transformer increases, the size of the heat sink increases, which reduces the fluidity of the liquid, making it difficult for hot oil to reach distant ends. This results in uncertain heat dissipation and poor sealing performance, leading to increased costs.
It adopts a structure that combines corrugated heat dissipation and heat pipe heat dissipation. The tank body and the tank cover are connected by welding. Heat pipes and corrugated fin radiators are configured. Heat is conducted by circulating liquid working fluid. Combined with distributed layout and modular design, it can adapt to different capacity requirements.
It improves heat dissipation efficiency, reduces temperature rise, extends transformer life, reduces the risk of oil leakage, lowers maintenance costs, and adapts to different environmental needs.
