Problems solved by technology

[0007] The Seebeck coefficient of metals is significantly smaller than that of semiconductors, so although metals are widely used as thermocouples, thermoelectric cooling or power generation using metal material junctions cannot be practical
In addition, although the generated thermoelectric effect is utilized by weaving two kinds of metal wires into a fabric, there is a problem that the thermoelectric force cannot be generated due to the electrical contact resistance at the joint point between the two kinds of metals due to the interlaced structure of the fabric structure.

Embodiment Construction

[0019] The three-dimensional orthogonal fabric for thermoelectric use of the present invention makes the warp openings into upper and lower groups through the opening movement of the heald frame of the textile machine, and introduces weft threads into the warp threads of the openings through the picking motion, and then repeatedly introduces them into the openings by using a reed. The weft thread is pushed to the front part of the woven fabric to complete the reed needle movement of the warp thread and weft thread to weave. The above-mentioned three-dimensional orthogonal fabric for thermoelectricity is characterized in that the above-mentioned three-dimensional interweaving fabric includes the binding warp thread 11, the middle part The warp 12, the upper weft 21, the middle weft 22, and the lower weft 23, the above-mentioned binding warp is woven so as to be arranged in the thickness direction by passing through the above-mentioned upper weft, the middle weft, the lower weft, ...

Abstract

The present invention is characterized by forming a multi-layer fabric in a three-dimensional orthogonal fabric structure having countless junctions so that a thermoelectric effect can be produced even with a metallic material having low thermoelectric conversion efficiency. The thermoelectric junctions, middle warps and middle wefts on the upper layer and lower layer of the multi-layer fabric are formed of elastic yarns whereby a compression pressure is always maintained in the junctions. The multi-layer fabric can be used for thermoelectric cooling or thermoelectric generation with a low electric contact resistance.

Description

technical field [0001] The present invention relates to a three-dimensional orthogonal fabric for thermoelectricity that generates a thermoelectric effect (thermoelectric effect) in which thermal energy and electrical energy interact by forming a closed loop having junctions formed by two mutually different metal wires. Background technique [0002] When two ends of two different metal wires are connected to form a closed circuit and a temperature difference is formed between the two ends, a potential difference is generated between the two contact points. This phenomenon is called thermoelectric effect, and the potential difference generated at this time is called thermoelectromotive force. [0003] This thermoelectric effect can be divided into the Seebeck effect that uses the temperature difference between two ends to obtain electromotive force, the Peltier effect that uses electromotive force for cooling and heating, and the Thomson effect that generates electromotive fo...
