This square bare aluminum air-cooled heat exchanger is specifically designed for thermal management systems in miniature electric excavators, battery-driven aerial work platforms, small electric forklifts, and portable integrated energy storage equipment. It features two symmetrical L-shaped mounting brackets for horizontal clamping installation and includes a single upward bent 90° elbow pipeline joint with a horizontal straight outlet to form a complete coolant circulation loop.
The unit utilizes dense vertical serrated turbulence fins and internal flow channels created through integral vacuum brazing, making it compatible with low-viscosity ethylene glycol cooling fluid. This design effectively dissipates heat generated by small power battery packs, low-power drive motors, and miniature hydraulic systems during intermittent light-load operation of compact new energy equipment.
Bent pipeline prevents rigid collision with vehicle frame, buffers vibration transmission, and reduces pipeline fatigue cracking risk under long-term low-frequency vibration.
Dual-side multi-hole uniform fixed design evenly disperses overall vibration load, preventing local core deformation and pipeline leakage.
Large heat exchange area with low air resistance loss, compatible with miniature silent energy-saving fans to reduce auxiliary power consumption.
Full vacuum brazing eliminates internal micro-leakage risks with smooth internal flow channels that resist scaling and blockage.
Lightweight with high thermal conductivity, no coating thermal resistance loss, suitable for indoor workshop and low-corrosion environments.
