Abstract
A tunnel-plate type heat pipe is manufactured out of a tube having capillary parallel tunnels defined by partitions through shaping both ends of the tube, forming recesses in the partitions in the vicinity of each end of the tube, closing both ends of the tube to form a capillary tunnel container, cleaning the capillary tunnel container, and charging the capillary tunnel container with a predetermined amount of working fluid.

A method of manufacturing a heat pipe out of a tube having capillary parallel tunnels defined by partitions, comprising the steps of:
- shaping ends of the tube;
- forming recesses in the partitions in the vicinity of each of said ends of the tube;
- closing said ends of the tube to form a capillary tunnel container;
- cleaning said capillary tunnel container;
- and
- charging said capillary tunnel container with a predetermined amount of a predetermined working fluid.
A method of manufacturing a heat pipe out of a tube having capillary parallel tunnels defined by partitions, comprising the steps of:
- shaping ends of the tube;
- forming recesses in the partitions in the vicinity of each of said ends of the tube, said forming step including forming first holes from a surface of the tube, said first holes having the diameter smaller than twice the diameter of the capillary parallel tunnels, and closing openings of said first holes;
- closing said ends of the tube to form a capillary tunnel container;
- cleaning said capillary tunnel container;
- and
- charging said capillary tunnel container with a predetermined amount of a predetermined working fluid.
A method of manufacturing a heat pipe out of a tube having capillary parallel tunnels defined by partitions, comprising the steps of:
- shaping ends of the tube;
- forming recesses in the partitions in the vicinity of each of said ends of the tube;
- crushing end portions of the tube;
- closing said ends of the tube to form a capillary tunnel container;
- cleaning said capillary tunnel container;
- and
- charging said capillary tunnel container with a predetermined amount of a predetermined working fluid.
