Title:
THERMOELECTRIC CONVERSION DEVICE
Document Type and Number:
WIPO Patent Application WO/2019/092876
Kind Code:
A1
Abstract:
Provided is a thermoelectric conversion device that can diffuse heat uniformly at the surface, can thermally insulate the heat-generating end from the heat-absorbing end of a thermoelectric conversion element pair without giving rise to deformation in the form of bumps and dips due to application of pressure, and has high durability owing to the very strong join with the sheets sandwiching the thermoelectric conversion chip. This thermoelectric conversion device 1 comprises: a thermoelectric module layer 20 wherein a thermoelectric conversion chip 21 is surrounded by a thermal insulation rubber 22 containing a rubber component 22a and a hollow filler 22b forming a plurality of cavities that are independent from one another; an insulation base layer 10 and an insulation middle layer 30, which are thermal conductive insulation sheets, sandwiching the thermoelectric module layer 20; a heat diffusion layer 40 having a higher thermal conductance than those of the insulation base layer 10 and the insulation middle layer 30 and stacked on the insulation middle layer 30; and a thermal radiation layer 50 having thermal conductance and stacked on the heat diffusion layer 40. At least one pair among the adjacent layers 10, 20, 30, 40, 50 is joined through a chemical bond.
