Abstract

The invention discloses a power thermocouple conversion element with a long-range concentrated cooling mode and especially relates to a structure that has a longitudinal extension form and has a high temperature section, a boundary section, and a cooling section. The high temperature section is direction arranged in a heat source; a boundary section is delimitation between the heat source and a cold source; and the cooling section is arranged in the cold source. The whole element is packaged by a protection housing. A thermocouple set, a metal flow deflector and an electrothermal circuit are arranged in the thermocouple conversion element, wherein the thermocouple set are first in parallel connection and then is in series connection as well as the electrothermal circuit is connected with a transition conductor; and all cold junction nodes of the electrothermal circuit are concentrated at the cooling section of the thermocouple conversion element for cooling. According to the invention, a heat transfer process and a cooling process of a thermocouple conversion element are reinforced, so that it is beneficial to fully utilize energies of a heat source as well as to improve an outputpower and reduce costs; moreover, it is also beneficial to design and develop a compact thermoelectric conversion apparatus and to improve a power density index.

Description

technical field

[0001] The invention relates to a thermoelectric direct conversion element, in particular to a long-distance centralized cooling power thermocouple conversion element. Background technique

[0002] The basis of thermoelectric conversion is Seebeck effect, Peltier effect and Thomson effect. When two conductors of different materials are connected into a closed loop, and the temperature of the joints (or junctions) at both ends of the loop is different, a current will be generated in the loop. This circuit is called thermoelectric circuit, the current is called thermal current, and the corresponding electromotive force is called thermal electromotive force or Seebeck electromotive force; among them, the node with high temperature is called working end or hot end, and the node with low temperature is called reference end or cold end. Industrial techniques are used to weld the joints into a common product called a thermocouple.
