A PHP is a passive, wickless heat transfer device consisting of a capillary loop, evacuated and partially filled with a working fluid, with alternated heating and cooling zones. The PHP light structure (4kg/m2), flexibility and moderately high heat transfer capability (30W/cm2) are interesting for automotive cooling applications. During their motion, vehicles withstand different speeding-up, which may influence the PHP behavior. The braking and the turning accelerations are the most critical reaching over ±1g for passenger cars, more for sport cars. Therefore, numerical simulations have been carried out to analyze the performances of a stand-alone PHP-based cooling system under transient accelerations.

Abstract

A PHP is a passive, wickless heat transfer device consisting of a capillary loop, evacuated and partially filled with a working fluid, with alternated heating and cooling zones. The PHP light structure (4kg/m2), flexibility and moderately high heat transfer capability (30W/cm2) are interesting for automotive cooling applications. During their motion, vehicles withstand different speeding-up, which may influence the PHP behavior. The braking and the turning accelerations are the most critical reaching over ±1g for passenger cars, more for sport cars. Therefore, numerical simulations have been carried out to analyze the performances of a stand-alone PHP-based cooling system under transient accelerations.
