RÉSUMÉ

New generation automotive technology is moving towards more energy efficient and renewable systems to reduce greenhouse emissions and fuel consumption. In the automotive, active thermal management of different components consume extensive energy and can be looked at to reduce power consumption. The present paper investigates the potential of loop heat pipes for automotive thermal management. Applications that has been investigated includes battery cooling in electric vehicles, fuel cell cooling in fuel cell operated cars, dashboard thermal control and power electronic cooling. The basic module in these applications includes a combined system with heat pipes to collect heat from the heat source and loop heat pipe to transfer this heat to the remote location against or in gravity favorable direction. Two prototypes of loop heat pipe with cylindrical evaporator, 25 mm diameter & 150 mm length, and heat transfer distance of 250 mm and 1000 mm respectively has been fabricated and tested. Both the prototypes were able to transfer more than 500 W of heat in different orientations and presented minimum overall thermal resistance of 0.1 °C/W at maximum input heat load. Loop heat pipe designs have been tested for different operating conditions and configurations, as required in automotive. In conclusions, loop heat pipes will provide an energy efficient passive thermal control solution for next generation low emission automotive.
