Heat pipe having a substantially unidirectional thermal path
Abstract
Abstract THE DISCLOSED HEAT PIPE INCLUDES A HERMETICALLY SEALED CHAMBER HAVING FIRST AND SECOND HEAT TRANSFER REGIONS. A FLUID CAPTURING WICK LOCATED IN THE VICINITY OF THE FIRST REGION AND A CAPILLARY WICK CONTAINING A VOLATILE WORKING FLUID ARE DISPOSED WITHIN THE CHAMBER. THE CAPILLARY WICK EXTENDS FROM THE FIRST TO THE SECOND REGION OF THE CHAMBER. WHEN HEAT IS APPLIED TO THE FIRST REGION, THE HEAT PIPE ACTS AS A THERMAL CONDUCTOR, TRANSFERRING HEAT FROM THE FIRST REGION TO THE SECOND REGION BY MEANS OF THE EVAPORATION AND SUBSEQUENT CONDENSATION OF THE WORKING FLUID. THE CONDENSED WORKING FLUID RETURNS TO THE FIRST REGION OF THE CHAMBER BY CAPILLARY ACTION VIA THE CAPILLARY WICK. WHEN HEAT IS APPLIED TO THE SECOND REGION OF THE CHAMBER, THE HEAT IS APPLIED TO THE PREVENT HEAT FLOW TO THE FIRST REGION.
