Problems solved by technology

At the same time, the thermocouples in the thermoelectric tube are arranged at the same level along the axial direction, so a special-shaped electrode can be used, which greatly improves the problem of poor contact and completely solves the problem of difficult processing of N and P-type elements in the thermoelectric tube. Further improvement of thermoelectric tube efficiency lays the foundation

Abstract

The invention relates to a vacuum thermoelectric tube, comprising: an inner tube, an outer tube, a vacuum cavity between the inner layer of the outer tube wall (1) and the outer layer of the inner tube wall (2); wherein the P-type element (3) and the N The type elements (4) are alternately arranged in the vacuum cavity along the direction parallel to the axis of the thermoelectric tube; one end of the P type element (3) and the N type element (4) are connected through the inner electrode (5), and the other end is connected through the outer electrode (6 )connect. The quality of the vacuum thermoelectric tube of the present invention is lighter, and the output energy efficiency per unit area is higher; and it can adapt to a higher temperature working environment and has wide adaptability.

Description

technical field [0001] The invention belongs to the technical field of thermoelectric elements, in particular to a vacuum thermoelectric tube. Background technique [0002] Energy is the cornerstone of human development. With the increase of the global population, the existing traditional energy such as coal, oil, and natural gas can no longer meet people's needs. At the same time, it has brought about increasingly serious environmental problems, and it is imminent to find new energy. Thermoelectric devices have attracted widespread attention because they can realize the direct conversion of thermal energy and electrical energy by utilizing the Seebeck effect and the Peltier effect (Peltier), that is, the direct conversion of thermal energy and electrical energy under solid conditions. . [0003] It is hoped that thermoelectric technology can be used to recover waste heat from exhaust pipes such as automobile exhaust and boilers, so as to realize energy reuse. At present, ...
