Embodiment Construction

[0035] image 3 is an exploded view of elements of a thermoelectric watch PH according to an embodiment of the present invention. Watch PH includes:

[0036] - Case Middleware CR;

[0037] - plate PT mounted in case middle piece CR;

[0038] - the element EA to be supplied with electrical energy and carried by the plate PT;

[0039] - back cover FD fixed to case middle piece CR;

[0040] - a thermoelectric generator comprising a thermoelectric module MT comprising a hot plate PC, a cold plate PF and a semiconductor pillar PS extending between the hot plate PC and the cold plate PF;

[0041] - The supporting element SP of the case middle CR mechanically connected between the back FD and the plate PT, between which the thermoelectric module MT is arranged.

[0042] The support element SP has the double function of a shock absorber (protecting the thermoelectric modules from any impact) and means for removing heat towards the case middle CR.

[0043]The support element SP i...

Abstract

The present invention relates to a thermoelectric watch (PH). The thermoelectric watch including a thermoelectric module (MT) including a hot plate (PC) and a cold plate (PF) connected by semiconductor pillars (PS), wherein the hot plate (PC) is thermally connected to the back cover of the watch (PH), the cold plate (PF) is thermally connected to the case middle of the watch (PH) via a support element with at least two branches (BC), at least two branches (BC) have a common end on which is held the cold plate (PF) of the thermoelectric module, and at least two branches (BC) are flexible to absorb shocks.

Description

technical field [0001] The invention relates to the technical field of watches provided with thermoelectric generators, known as thermoelectric watches. Background technique [0002] This thermoelectric generator converts heat flux into electrical energy that can be used to power the watch's electronics (watch movement, dial lighting, etc.). refer to figure 1 , the thermoelectric generator GT comprises thermoelectric modules MT and transmission lines CT in a conventional manner. The thermoelectric module MT comprises a cold plate PF and a hot plate PC, which are electrically insulated, substantially parallel to each other, and each have electrically conductive wire connectors DMf, DMc arranged adjacent to each other. The thermoelectric module MT also comprises a semiconductor post PS extending between the wire connectors DMc of the hot plate PC and the wire connectors DMf of the cold plate PF. The semiconductor posts PS are positioned such that each wire connector DMc of ...
