Long® Auxiliary Stacked Plate and Plate Fin Coolers


Thermal management is a critical area of engine design. To enhance vehicle efficiency, a certain percentage of fuel has to be consumed to overcome friction in powertrain components, such as the transmission, engine, and axle. Maintaining proper oil temperature in the powertrain increases both efficiency and overall fuel economy.

Long® stacked plate coolers offer high durability and can stand alone or be integrated with other components as required. The plate-and-fin design, which employs fins between oil channels, provides high heat transfer performance and low air-side pressure drop. Both coolers are installed on vehicle fronts for auxiliary cooling of passenger cars and light trucks. 

Key Features

  • Variable stack heights match performance to the available space
  • Allows oil to easily travel from one end to the other
  • Superior high heat transfer performance
