Electric Coolant Pump for High-Temperature Power Generation Cooling Applications

OBJECTIVE: The objective of this SBIR effort will be to design, build and demonstrate an experimental coolant pump capable of continuous operation in an engine compartment while pumping coolant at 105°C Programs such as the Advanced Powertrain Demonstrator (APD), the Combat Vehicle Prototype (CVP) and the Next Generation Combat Vehicle (NGCV), as well as other Technology Insertion programs such as the Stryker Advanced Propulsion w/ On-Board Power (APOP), are leveraging the latest developments in high-temperature Silicon Carbide (SiC) technology to supply enormous amounts of electrical power while operating at extremely high coolant temperatures (105 degrees Celsius). We will develop a cooling pump that is capable of providing high-temperature liquid cooling to these devices while surviving the temperatures found in a ground vehicle engine compartment, operate from a 24 VDC. In Phase I we identify and analyze the necessary technologies this electric coolant pump to operate in an enclosed compartment at 125 degrees Celsius and at steady-state flow rate of 95 to 132 liters per minute and a pressure rise of 1.7-2.1 bar. In Phase II we will design, build and demonstrate the experimental prototype electric coolant pump that incorporates the key technologies and characteristics identified in Phase I.
