Phase changing energy storage micro thermoelectric power source

Abstract

A phase transition stored energy micro-type thermoelectricity power supply comprises an upper cover (1) and a lower cavity (2) which are connected with each other. The upper cover (1) and the inside surface of the lower cavity (2) are both provided with a thermal insulation layer (3). The center of the lower cavity (2) is provided with a heat source cavity (4) which stores high temperature stored energy phase-change material. The heat source cavity (4) is internally provided with a promoter (5). The periphery of the heat source cavity (4) is provided with a micro-type thermoelectricity electric generator (6). One surface of the micro-type thermoelectricity electric generator (6) is glued with the outside surface of the heat source cavity (4). The other surface of the micro-type thermoelectricity electric generator (6) is closely contacted with a cold source cavity (7) which stores low temperature phase-change material. An output lead (8) connected with the output conductive junction point of the micro-type thermoelectricity electric generator (6) is arranged outside the whole of the micro-type thermoelectricity power supply. The phase transition stored energy micro-type thermoelectricity power supply has the following advantages of small volume, being lightweight and portable and repeated use.

Description

technical field [0001] The invention relates to a device for generating electricity based on temperature difference, in particular to a phase-change energy storage miniature thermoelectric power supply based on temperature difference for electricity generation. Background technique [0002] With the rapid development of micro-electro-mechanical systems (MEMS) technology, such as micro-sensors, micro-motors, micro-aircrafts, flexible pipe robots for diagnosis, etc., have been gradually popularized and applied, although many functional components of micro-electro-mechanical systems (MEMS) devices, Microsensors, microactuators, micropumps, microvalves, etc., can already be made very small, but most of the power sources that provide energy for microelectromechanical systems (MEMS) devices are powered by external wires, or use chemical batteries, or relatively In terms of volume, it is inconvenient to use, or it has a short service life or is not environmentally friendly.
