Title:
EXTRUSION NOZZLE APPARATUS AND METHOD FOR EXTRUDING THERMOELECTRIC MATERIAL USING EXTRUSION NOZZLE APPARATUS
Document Type and Number:
WIPO Patent Application WO/2021/230406
Kind Code:
A1
Abstract:
The present invention relates to an extrusion nozzle apparatus and a method for extruding a thermoelectric material using the extrusion nozzle apparatus. An extrusion nozzle apparatus according to one embodiment of the present invention comprises: an inlet for introducing material; an outlet for discharging the input material; and a discharge pipe which is formed in a multi-stage shape including a plurality of stages such that the input material moves in a first direction from the inlet toward the outlet while being pressurized inside the discharge pipe. The cross-sectional area of the plurality of stages in a direction perpendicular to the first direction may progressively decrease from the inlet to the outlet. Accordingly, the thermoelectric performance of a thermoelectric material can be improved, and production cost and production time can be reduced.
