AI Technical Summary
The existing annular air duct heat dissipation structure of epoxy cast dry transformers has problems such as low airflow organization efficiency, low air velocity and high wall heat exchange thermal resistance, which cannot achieve active airflow organization and directional heat transfer.
A spiral flow channel is formed by setting a spiral flow guide groove on the outside of the second epoxy insulation layer and setting an expansion section and a contraction section on the inside of the first epoxy insulation layer, combined with a high thermal conductivity insulation coating. The Venturi effect and swirling effect are used to improve the airflow velocity and heat exchange efficiency.
It achieves orderly airflow organization and directional heat transfer, improves heat dissipation efficiency, and solves the problems of low airflow organization efficiency and heat accumulation in dead zones in traditional structures.
