PURPOSE:To prevent the preclusion of evaporation of operating fluid and improve heat transfer characteristics by a method wherein the operating fluid is heated after pouring and non-condensible gas, generated by heating, is sealed into a nozzle employed for the pouring. CONSTITUTION:A container 1 is provided with a nozzle 2 consisting of a small pipe and the nozzle 2 is sealed temporarily remaining a predetermined length from the container 1 after pouring operating fluid 10 into the container 1. Subsequently, the container 1 is heated to a predetermined temperature to evaporate the operating fluid 10, then, dissolved gas, such as O2, CO2 or the like is separated or deposit on the internal surface of the container 1 is decomposed by heat thereby generating gas. These non-condensible gas enters into the nozzle 2 and the nozzle 2 is filled with non-condensible gas. The container 1 is heated for a predetermined period of time in such manner and, thereafter, the base end of the nozzle 2 at the side of the container 1 is sealed. As a result, the non-condensible gas 11 is removed perfectly and the operating fluid 10 can be supplied whereby a heat pipe, showing expected heat transfer characteristics, may be obtained. |
