Innovative Radiator Material Durability and Sustainment

NCMS Project #: 141003

Problem: The primary means of heat removal for internal combustion engines is a liquid-filled system with its primary cooling unit being a radiator. Historically, a brass-copper core has been used, but recently aluminum has been gaining popularity.  While aluminum radiators provide some advantages, this rapid change is creating a durability and sustainment gap impacting the heavy off-road construction, mining, oil and other vehicle-centric industries.

Benefit: Developing a new repair procedure and improving system documentation will result in long term success supporting multiple vehicle system requirements using legacy copper brass radiators.

Solution/Approach: Shock, vibration and severe off-road duty cycles create more failures and maintenance actions in aluminum versus more robust copper-brass radiators.  This project will explore design improvements on repairs to both legacy copper/brass and aluminum radiators that will improve radiator availability and reduce maintenance and sustainment actions and cost.  The solution will begin with the current platform capabilities and leverage those capabilities to meet Army requirements
