Abstract

The present invention relates to a path-related thermoelectric dual-field dual-function device, which includes a central functional area and a wrapping area distributed around it. The functional device switches the aggregation and stealth functions according to the direction of the physical field. The physical field includes a thermal field and an electric field. When the aggregation function is realized, the functional device gathers the external isotherms and equipotential lines in the central functional area, and the temperature and electric potential gradients of the central functional area are significantly improved without disturbing the distribution of the external thermal field and electric field. When the stealth function is realized, the functional device allows the external heat flow and current to bypass the central functional area, and the temperature and electric potential gradients of the central functional area approach zero, and the distribution of the external temperature field and electric field is not disturbed. Compared with the prior art, the present invention can broaden the application field of thermoelectric dual-function devices and has potential application value in thermal management of electronic devices.
