This paper reports on the predictive capabilities of a new commercial software called aCool with a more sophisticated representation of heat pipes that accounts for both the thermal resistance and the heat transport limitations in CFD models of thermal solutions such as heat sinks. Rather than rely solely on the theoretical heat transport capabilities of heat pipes, the properties of the heat pipes...
Power electronics devices such as MOSFET's, GTO's, IGBT's, IGCT's etc. are now widely used to efficiently deliver electrical power in home electronics, industrial drives, telecommunication, transport, electric grid and numerous other applications. This paper discusses cooling technologies that have evolved in step to remove increasing levels of heat dissipation and manage junction temperatures to...
Two-phase pumped-loop systems are being actively considered for cooling of high heat load electronics. In the present study, a computational method based on a two-level approach is developed for generalized system-level analysis of two-phase pumped-loop cooling systems containing multiple branches under steady-state conditions. Detailed one-dimensional analysis of components with distributed two-phase...
