摘要: Investigation of heat-exchange processes in the evaporator a loop heat pipe is important for development transfer devices with low thermal resistances. A two-dimensional mathematical model active zone presented. Three modes vapor generation wick have been examined, where each differs mechanism phase formation and saturation capillary structure: 1) evaporation to grooves, 2) volumetric two-phase zone, 3) separated from heated wall by dried zones. Conditions identifying changes between formulated. Structural characteristics different pore sizes taken into account. Using numerical-analytical method, results were obtained three copper pipes biporous wicks, working fluid was water one methanol other two. The heat-load dependent temperature drop grooves has Additionally, comparative analysis calculated experimental performed.
