Thermoelectric rotator based on temperature-dependent coordinate transformation theory, and design method thereof

Abstract

The invention belongs to the technical field of new materials and infrared, and particularly relates to a thermoelectric rotator based on a temperature-dependent coordinate transformation theory, and a design method thereof. According to the invention, the transformation theory is expanded from a thermal field to a thermoelectric field, and the temperature-dependent transformation thermoelectricity is provided and applied to the thermoelectric effect. The method comprises the following steps: establishing a thermoelectric field for controlling intrinsic physical parameters to be related to temperature by utilizing a temperature-dependent thermoelectric conversion theory, performing rotation conversion on a space of a specific region, changing the directions of local heat flow and current without changing the distribution of background heat flow and current, and converting the conversion of the space into the conversion of material attributes to realize the design of the thermoelectric rotator. The thermoelectric rotator has universality, and the thermoelectric field can be flexibly regulated and controlled through coordinate changes. Finite element simulation verification shows that the thermoelectric rotator is safe and feasible, provides a new idea for flexible control of a thermoelectric field, has a wide practical application prospect, and can be used for waste heat power generation, device protection and the like.

Description

technical field [0001] The invention belongs to the field of new materials and infrared technology, and in particular relates to a thermoelectric rotator based on the temperature-dependent coordinate transformation theory and a design method thereof. Background technique [0002] In recent years, with the advancement of science and technology, the extensive use of electronic devices has brought great convenience to people, but at the same time some problems have also emerged, such as electronic devices heating, causing damage to devices, etc. The more delicate the device is, the easier it is to be scrapped due to high temperature. The reason for the heating of these devices is that the device is passed through the current to generate Joule heat, but the heat cannot be dissipated in time, resulting in excessive temperature and the device is burned out. Therefore, it is imminent to solve the problem of devices being scrapped due to high temperature. Improving the heat resistan...
