Introduction to Commercial and Off-Road Vehicle Cooling Airflow Systems

Vehicle functional requirements, emission regulations, and thermal limits all have a direct impact on the design of a powertrain cooling airflow system. Given the expected increase in emission-related heat rejection, suppliers and vehicle manufacturers must work together as partners in the design, selection, and packaging of cooling system components. An understanding and appreciation of airflow integration issues and vehicle-level trade-offs that effect system performance are important to the team effort. The severe duty cycles, minimal ram air, and sometimes unconventional package layouts present unique challenges.

The goal of this two-day seminar is to introduce engineers and managers to the basic principles of cooling airflow systems for commercial and off-road vehicles. Participants will learn about vehicle/product constraints, integration issues, cooling airflow, system resistance, fans, shrouds, radiators, coolers, estimating heat rejection, thermal accumulation, air recirculation, system performance, and underhood airflow. Basic concepts will be reinforced with in-class discussion of case studies.

Included in this seminar is the SAE paper A Systems Engineering Approach to EngineCooling Design; The 44th L. Ray Buckendale Lecture.
