Thermal Management Through Insulation Design—Passenger Car Platforms

Abstract

AbstractIn a passenger car design, thermal safety and performance are the key attributes that decide the successful launch and customer acceptance of a product platform. Thermal management is becoming more and more challenging with the stringent regulations about emissions and safety. The BSVI—stage two regulations and CAFE norms require the powertrain and the vehicle systems to be highly efficient in terms of fuel economy (FE) and at the same time meeting the regulatory requirements. It is very important that the vehicle packaging and insulation strategies should lead to the safe functioning of the vehicle system throughout the real world and the extreme conditions. Also, for better FE performance, the air intake system should be sufficiently masked from the high underhood temperatures resulting from engine operation. This chapter includes concepts and validation aspects of thermal insulation design. The topics covered include the basics of insulation, thermal design considerations, material selection, vehicle level thermal assessment, and manufacturing.
