Abstract
PURPOSE: To improve safety and heat transfer efficiency and to facilitate production by filling a container with a preset quantity of a heating agent liquid and by heating the container at a temperature lower than the boiling point of the liquid.
CONSTITUTION: A container 10 to be used as a roll body is composed of a circumferential wall 10a, which is made of a refractory material having excellent thermal conductivity and which has its outer circumference subjected to an offset preventing treatment, and two end plates 10b and 10c which are formed at the both ends. Cylinders 11 and 12 are fixed to the centers of the respective end plates so that a heat pipe roll can be rotatably supported. On the other hand, one of the end plates 10b is formed at is suitable position with a threaded hole 13, into which a bolt 14 is fastened so that the heating agent liquid can be confined after it is injected. The other end plate 10c is formed with an exhaust port 15a, through which such an exhaust member 15 can be forced thereinto as is made of a material which can be dissolved at a slightly lower temperature than the boiling point of the liquid. As a result, the abnormal high internal pressure, if any, can be relieved to the outside. Thus, only the liquid can be used to enhance the safety and the heat transfer efficiency.
