Abstract
An embodiment provides a mass-manufacturing method of new structure thermoelectric elements, including: (a) filling a thermoelectric material powder so as to surround the inner and outer parts of a spacer portion located inside a mold portion; (b) pressurizing the spacer portion by a punch portion; (c) sintering the thermoelectric material powder using spark plasma to produce a sintered body; and (d) cutting the sintered body to a preset size to manufacture a plurality of thermoelectric elements.
Claims5
A manufacturing method of thermoelectric elements, the manufacturing method comprising:
- filling a thermoelectric material powder to surround inner and outer parts of a plurality of spacer portions disposed inside a mold portion;
- pressurizing, by a punch portion, the plurality of spacer portions;
- sintering, by a spark plasma sintering device, the thermoelectric material powder using spark plasma to generate a plurality of sintered bodies;
- and
- cutting the plurality of sintered bodies to a preset size to manufacture a plurality of thermoelectric elements,
- wherein the filling the thermoelectric material powder comprises:
- supplying the thermoelectric material powder into a spacer portion disposed at a lowermost position after the spacer portion disposed at the lowermost position among the plurality of spacer portions is disposed at an upper part of a lower punch disposed in the punch portion;
- supplying the thermoelectric material powder into an n-layer spacer portion after the n-layer spacer portion among the plurality of spacer portions is placed at an upper part of the spacer portion disposed at the lowermost position;
- and
- supplying the thermoelectric material powder into a spacer portion disposed at an uppermost position after the spacer portion disposed at the uppermost position among the plurality of spacer portions is placed at an upper part of the n-layer spacer portion, and
- wherein the supplying the thermoelectric material powder into the spacer portion disposed at the lowermost position comprises:
- placing a sheet portion disposed at the lowermost position among a plurality of sheet portions at the upper part of the lower punch;
- supplying the thermoelectric material powder to the upper part of the sheet portion disposed at the lowermost position;
- placing the spacer portion disposed at the lowermost position at an upper part of the thermoelectric material powder supplied to the upper part of the sheet portion disposed at the lowermost position;
- supplying the thermoelectric material powder to the upper part of the spacer portion disposed at the lowermost position;
- placing one sheet portion among the plurality of sheet portions at the upper part of the thermoelectric material powder supplied to the upper part of the spacer portion disposed at the lowermost position;
- and
- placing an n-layer support portion among a plurality of support portions at an upper part of the one sheet portion.
