Ultra High Efficiency Blower System for Engine and Vehicle Applications

Conventional Fans and radiator coolant systems for over the road and military applications have been a major source of inefficent engine and vehicle operations. The technology has been virtually unchanged for decades and is plaqued with warranty andservice issues. As the engine manufactures move to a complete thermal managent system as a replacement to the current technology, a compact high efficency electric blower will be a major component.The goal of this project is to design,and demonstrate the feasibility of a compact high efficiency electric blower for primary cooling on military and commercial vehicles. This blower will be based on an existing blower developed by Engineered MachinedProucts (EMP) for use as a secondary cooling device. There are a number of advantages of the EMP blower over conventional fan technology. The primary benefit is the improved efficiency of this unit. Because this blower will be more efficient than current fan technologies, it should improve fuel economy aswell as emissions. Fuel econnomy can also be improved by reducing parasitic losses because the blower will be controllable. The blowers unique design will allow for the use in a modular system. The same blower could be used across multiple engine platformsthus reducing inventories.
