Apparatus for manufacturing thermoelectric conversion element

摘要

The present invention relates to an apparatus and a method for manufacturing a thermoelectric conversion element. The present invention provides an apparatus for manufacturing a thermoelectric conversion element that can easily realize a high-density array of thermoelectric conversion elements and secure connection reliability. This is an apparatus for manufacturing a thermoelectric conversion element that sucks a p-type or n-type thermoelectric conversion material into heat-resisting insulating tube 102 and includes preheating apparatus 205 that can heat tube 102 to a predetermined temperature before sucking the melted thermoelectric conversion element. Tube 102 whose temperature condition is adjusted by being heated by preheating apparatus 205 is inserted into crucible 204 and the molten thermoelectric conversion material is sucked into tube 102 by decompression apparatus 201.

主权项

1. An apparatus for manufacturing a thermoelectric conversion element, comprising:
a crucible configured to store a molten thermoelectric conversion material; a heating apparatus arranged on an outer perimeter of the crucible, the heating apparatus being configured to heat the thermoelectric conversion material in the crucible to a temperature equal to or higher than a melting temperature of the thermoelectric conversion material; a preheating apparatus arranged above the crucible; a passage as part of the preheating apparatus, the passage configured to communicate between inside part of the crucible and an upper side of the heating apparatus; a tube made out of heat-resistant insulating material and configured to be heated by the preheating apparatus to a temperature lower than the melting temperature, a first end of the tube inserted into the crucible via the passage; and a decompression apparatus connected to the second end of the tube.
