Product Overview

Adaptability of Heat Dissipation System: Heat transfer relies on natural oil circulation without the need for additional power devices — the heat generated by the iron core and windings heats the oil, which then rises naturally, dissipates heat and cools down through the oil tank wall and corrugated fins, and finally falls back to form a stable cycle. The matched corrugated fin oil tank adopts an elastic corrugated structure: when the oil temperature rises, the corrugated fins expand automatically, increasing the heat dissipation area by 15%-20%; when the oil temperature drops, the fins contract to reduce heat loss. This design balances heat dissipation efficiency and energy-saving needs, avoiding energy waste of traditional fixed heat dissipation structures.
