Method and an appratus for constructing a heat pipe

摘要

A method for constructing a heat pipe, comprising the steps of providing a tube having an open end and a opposite closed end; filling a tube with a predetermined volume of working fluid; connecting a vapor trap to the open end of the pipe; evacuating the tube for a predetermined period of time to remove non-condensable gases from the tube; and sealing the tube wherein the step of evacuating the tube includes the steps of applying a vacuum to the open end of the pipe.

1. A method for constructing a wickless heat pipe, comprising the steps of:
providing a tube having an open end and an opposite closed end; filling the tube with a predetermined volume of working fluid; connecting a vapor trap to the open end of the tube; evacuating the tube by applying a vacuum to the open end of the tube for a predetermined period of time to remove non-condensable gases from the tube; then after filling the tube with a predetermined volume of working fluid; sealing the tube, weighing the tube after filling the tube with a predetermined volume of working fluid and before evacuating the tube; re-weighing the tube after evacuating the tube, and recording the mass of vaporized working fluid lost during evacuation of the tube.
