Introduction to Commercial and Off-Road Vehicle Cooling Airflow Systems C0738

Topics: Powertrain & Propulsion

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. The goal of this two-day course 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.

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

Learning Objectives

By attending this course, you will be able to:

  • List fundamental factors and constraints of commercial and off-road vehicle cooling airflow systems
  • List vehicle requirements and system integration issues
  • Describe system resistance, fan, shroud, installation effects, and radiator characteristics
  • List fan/shroud aerodynamic design considerations and installation effects
  • Estimate heat rejection and thermal accumulation for system analysis
  • Analyze performance of diesel cooling airflow system
  • List alternatives for program management trade-off discussions on cooling airflow systems

Who Should Attend

OEM and supplier engineers and managers who are involved with vehicle cooling systems, or who interface with vehicle program management on these issues, will benefit from this course. Graduate-level participants interested in cooling systems will also find it instructive.


Participants should have an undergraduate engineering degree. Exposure to thermal product development is helpful, but not required.
