Abstract:
1. A thin film type thermoelectric module device, comprising: a main hollow pillar structure with a hollow region therein, wherein the main hollow pillar structure is formed by stacking a plurality of ring-shaped thin film type thermoelectric module elements and each of the ring-shaped thin film type thermoelectric module element comprises a plurality of thermoelectric thin film pairs each comprising a p-type thermoelectric thin film element (p-type TEE) and an n-type thermoelectric thin film element (n-type TEE) arranged in a ring on a ring-shaped substrate; the thin film type thermoelectric modules arranged along a ring direction on the ring-shaped substrate, wherein an insulating and thermal conductive layer respectively covering an inner sidewall of the hollow region and an outer sidewall of the hollow pillar main structure, wherein a cooling source or a heating source is disposed within the hollow region or an outer side of the hollow pillar main structure, wherein top surfaces of the p-type thermoelectric thin film elements and the n-type thermoelectric thin film elements of a lower ring-shaped thin film type thermoelectric module element directly contact a bottom surface of the ring-shaped substrate of an upper ring-shaped thin film type thermoelectric module element, wherein the p-type thermoelectric thin film elements (p-type TEE) and the n-type thermoelectric thin film elements (n-type TEE) of the same layer are arranged alternatively with a direction parallel to a surface of the ring-shaped substrate.
