Problems solved by technology

[0009] However, when a plurality of such π-type thermoelectric conversion elements are connected, there is a problem that the manufacturing process becomes complicated and labor-intensive.
In addition, due to the influence of thermal strain due to the difference in the thermal expansion coefficient of each component or repeated thermal strain changes, interface fatigue occurs, and there is a problem of performance degradation.

Embodiment Construction

[0063] Hereinafter, the thermoelectric conversion device of the present invention will be described in detail based on preferred embodiments shown in the drawings.

[0064] In addition, in the following, "-" which shows a numerical range includes the numerical value described on both sides. For example, ε is a numerical value α to a numerical value β, which means that the range of ε is a range including the numerical value α and the numerical value β, and expressed in mathematical notation, it is α≤ε≤β.

[0065] Regarding the angle, unless otherwise specified, it means that the difference from the exact angle is within a range of less than 5°. The difference from the exact angle is preferably less than 4°, more preferably less than 3°.

[0066] In addition, "same" and "same" are defined as including an error range generally allowed in the technical field. In addition, "the whole surface" and the like include not only the case of 100%, but also the error range generally allow...

Abstract

Provided is a thermoelectric conversion device which is highly self-supportive, is highly installable, and is easily installable in heat sources of various shapes. The thermoelectric conversion deviceis equipped with an insulating substrate, a plurality of thermoelectric conversion layers positioned on the principal surface of the insulating substrate with a pre-set interval interposed therebetween, and a plurality of wiring members positioned on the principal surface of the insulating substrate so as to sandwich each of the thermoelectric conversion layers. The thermoelectric conversion device also has: a bellows-shaped module band formed in a bellows structure by alternately folding upward and folding downward, and having a plurality of through-holes formed in each of a plurality of plate-shaped sections formed by the bellows-shaped folding of the insulating substrate; and a linear member that passes through the plurality of through-holes and transects the plurality of plate-shapedsections.

Description

technical field [0001] The present invention relates to a thermoelectric conversion device using a plurality of thermoelectric conversion elements. Background technique [0002] A thermoelectric conversion material capable of mutually converting thermal energy and electrical energy is used in a thermoelectric conversion element such as a power generation element or a Peltier element that generates electricity by heat. [0003] The thermoelectric conversion element has an advantage of being able to directly convert thermal energy into electricity, and does not require moving parts or the like. Therefore, a thermoelectric conversion module (power generation device) in which a plurality of thermoelectric conversion elements are connected can easily obtain electric power without running costs by installing, for example, a calciner or a place where heat is discharged from various equipment in a factory. [0004] As such a thermoelectric conversion element, a so-called π-type the...
