PURPOSE: To impove the heat exchange efficiency of the titled vessel by a method wherein a doughnut type heat pipe itself which is used for the tranfer of heat is used as the vessel for the metal hydride at the same time and a hydrogen inlet and outlet pipe is provided at the central hollow section of the heat pipe.
CONSTITUTION: The open ends of the doughnut type heat pipe are closed with covering plates 4a and 4b and the metal hydride 6 is packed into the central hollow section 5 of the heat pipe. Further, the hydrogen inlet and outlet pipe 8 povided with a changeover valve 7 is attached to the covering plate 4a and a porous pipe 9 is passed through the central hollow section 5 of the heat pipe in the axial direction in continuation with the pipe 8. The pipe 9 allows hydrogen to pass through the wall thereof although it does not allow the metal hydride 6 to do so. Thus, due to the fact that the heat pipe serves as the vessel for the metal hydride 6, it is possible to reduce a heat loss as sensible heat to the pressure resistant vessel and also it is possible to improve the heat exchange efficiency of the vessel since the sectional area of contact between the heat pipe and the metal hydride 6 is large.
