Cylindrical heat pipe

WebA heat pipe-based thermal management system is proposed for a battery module with cylindrical cells. Compared with the natural cooling, the temperature of the battery can be significantly reduced by about 14 degrees C in the 5 C discharge rate. A thermal equivalent circuit model (TECM) is developed to describe the thermal behavior of the ... WebThe pressure recovery in a cylindrical heat pipe has been investigated. The experiments cover average radial Reynolds numbers between 5 and 150 and average Mach numbers up to the velocity of sound. During preliminary experiments in a cylindrical, gravity-assisted heat pipe at high Mach numbers large condensate flow instabilities were observed.
