Peripheral Four Lug Trapezoidal Aluminum Marine Engine Heat Exchanger Plate Fin

This trapezoidal all-aluminum heat exchanger is specifically designed for compact small-and-medium screw air compressors. It features four outward extending mounting lugs on the frame perimeter, three parallel fluid nozzles aligned on the upper header, and one independent large-diameter outlet pipe at the bottom left. Dense vertical straight fins are bonded via one-piece vacuum brazing, forming fully isolated oil and gas dual flow passages to accomplish combined cooling of compressor lubricant and hot exhaust air.

The asymmetrical trapezoidal profile fits slanted narrow cabinet inner space, with nozzle bore, fin density and overall contour fully customizable for non-standard compact compressor OEM matching.

• Four-sided outer lug mounting structure with multi-point optional fixing positions to fit various irregular limited installation spaces of mini compressor cabinets
• Three parallel top integrated fluid nozzles that centralize all inlet pipelines on the upper section to reserve bottom space for drain valves and maintenance parts
• Separate bottom single large outflow nozzle that concentrates medium discharge to simplify downstream pipeline routing without crossing internal components
• High-density vertical straight fin air flues with low aerodynamic drag to cut power consumption of small supporting cooling fans for compact units
• Physically separated oil-air flow channels that completely block medium intermixing to prevent oil emulsification and high-temperature shutdown faults of compressors

• Material advantage: Thin lightweight integrated aluminum frame reduces overall unit weight, matching lightweight design requirements of mobile compact compressors
• Process advantage: One-time vacuum brazing eliminates split welding leakage seams, drastically lowering after-sales leakage maintenance rate of small compressor equipment
• Layout advantage: Top concentrated three-nozzle design frees bottom cabinet space, facilitating daily maintenance and drainage pipeline layout for compressor manufacturers
• Quality control: Every flow channel undergoes independent high-pressure leak testing; dimensional tolerance calibration of all four mounting lugs before packaging and delivery
• Customization advantage: Diverse trapezoidal compact size specifications, support personalized non-standard modification, satisfying global compact screw compressor OEM bulk supporting orders
