Abstract

A thermoelectric generator includes: a heat-receiving plate configured to receive heat; a cooling plate kept at a lower temperature than a temperature of the heat-receiving plate; and a thermoelectric generation module interposed between the heat-receiving plate and the cooling plate, the thermoelectric generation module including a plurality of thermoelectric elements, an outer sealing frame surrounding the thermoelectric elements, and a film sheet continuously entirely covering at least a first side of the thermoelectric elements and the outer sealing frame facing the heat-receiving plate; and a first heat insulation layer formed in a space that is defined between the heat-receiving plate and the thermoelectric generation module and that corresponds to the outer sealing frame.

First claim

1 . A thermoelectric generator comprising:
a heat-receiving plate configured to receive heat; a cooling plate configured to be kept at a lower temperature than a temperature of the heat-receiving plate; a thermoelectric generation module interposed between the heat-receiving plate and the cooling plate; and a fastener inserted through the heat-receiving plate, the cooling plate, and the thermoelectric generation module to fasten the heat-receiving plate, the cooling plate, and the thermoelectric generation module to each other, wherein the thermoelectric generation module comprises:
a plurality of thermoelectric elements,
one or more electrodes connected to the thermoelectric elements,
an outer sealing frame surrounding the thermoelectric elements and the one or more electrodes,
an inner sealing frame surrounding the fastener, the inner sealing frame being provided within the outer sealing frame,
a first film sheet continuously entirely covering at least a first side of each of the inner sealing frame, the thermoelectric elements, the one or more electrodes, and the outer sealing frame, the first side facing the heat-receiving plate,
a first heat insulation layer provided in a space that is defined between the heat-receiving plate and the thermoelectric generation module and that corresponds to the outer sealing frame,
a second heat insulation layer provided in a space that is defined between the heat-receiving plate and the thermoelectric generation module and that corresponds to the inner sealing frame, and
a heat transfer layer provided in a space that is defined between the heat-receiving plate and the thermoelectric generation module and that corresponds to the thermoelectric elements and the one or more electrodes,
wherein the heat transfer layer is configured to circumvent the first and second insulation layers to thereby transfer heat from the heat-receiving plate to the thermoelectric generation module.

5 . The thermoelectric generator according to claim 1 , wherein
the thermoelectric generation module is interposed between the heat-receiving plate and the cooling plate while being pressed by the heat-receiving plate and the cooling plate, and the fastener comprises a coil spring configured to apply a pressing force to the thermoelectric generation module through the heat-receiving plate and the cooling plate.

6 . The thermoelectric generator according to claim 1 , wherein
the outer sealing frame is bonded to the first film sheet.

7 . The thermoelectric generator according to claim 1 , wherein
the inner sealing frame is bonded to the first film sheet.

8 . The thermoelectric generator according to claim 1 , wherein
the first film sheet comprises film sheets each comprising a polyimide film and a copper film entirely covering one surface of the polyimide film, and the film sheets are respectively provided on the first side facing the heat-receiving plate and a second side facing the cooling plate of the thermoelectric elements and the outer sealing frame with the respective copper films facing the heat-receiving plate and the cooling plate.

9 . The thermoelectric generator according to claim 1 , wherein the heat transfer layer is provided at all portions between the heat-receiving plate and the thermoelectric generation module corresponding to the thermoelectric elements and the one or more electrodes.

10 . The thermoelectric generator according to claim 1 , wherein the first film sheet is extended in an in-plane direction.

11 . The thermoelectric generator according to claim 1 , wherein the one or more electrodes are positioned between the first film sheet and the thermoelectric elements.

12 . The thermoelectric generator according to claim 1 , wherein the inner sealing frame comprises a plurality of inner sealing frames that are provided within the outer sealing frame.

13 . The thermoelectric generator according to claim 1 , further comprising:
a second film sheet continuously entirely covering at least a second side of each of the inner sealing frame, the thermoelectric elements, the one or more electrodes, and the outer sealing frame, the second side facing the cooling plate.

14 . The thermoelectric generator according to claim 13 , wherein the outer sealing frame, the inner sealing frame, the first film sheet, and the second film sheet define a sealed space in which the thermoelectric elements and the one or more electrodes are disposed.

15 . The thermoelectric generator according to claim 14 , wherein the thermoelectric elements and the one or more electrodes are attached to the outer sealing frame and the inner sealing frame via the first and second film sheets.
