Thermoelectric module and thermoelectric exchange device

Abstract

An embodiment of the invention provides a thermoelectric module and a thermoelectric exchange device. The thermoelectric module comprises an upper substrate, a lower substrate, a thermoelectric structure, and at least two support columns. The thermoelectric structure comprises at least one group of thermoelectric elements, and each group of thermoelectric elements comprises a P-type thermoelectric element and an N-type thermoelectric element. The upper substrate and the lower substrate are in parallel, the at least two support columns are supported at an edge position between the upper substrate and the lower substrate, the P-type thermoelectric element and the N-type thermoelectric element of each group of thermoelectric elements are connected in an alternating way through electrodes of the upper substrate and electrodes of the lower substrate, and the materials of the support columns are ductile materials. The embodiment is advantageous in that, use service lifetime of the thermoelectric module can be prolonged.
