This square multi-lug aluminum plate fin heat exchanger features dual-side multi-position thick flange connectors and full-perimeter integrated mounting lugs, manufactured through integral vacuum brazing with bare original aluminum finish. The dense serrated turbulence fins expand heat exchange area, while separated independent runners support simultaneous heat exchange for three types of media. The multi-lug uniform stress design adapts to heavy vibration working conditions in construction machinery and energy storage equipment, with customizable flange hole size, lug quantity, and overall square dimensions for OEM matching.
