Micro thermoelectric power source with radioactive isotope

Abstract

The present invention discloses a radioactive isotope mini thermoelectric power supply which comprises a outer housing (1), heat power supply and a plurality of mini thermoelectric power generators (2) set between the outer housing (1) and the heat power supply; the heat power supply comprises a shielding cavity (3); a heat power supply chamber (8) that can store radioactive isotope is set on the central position of the shielding cavity (3); the shielding cavity (3) is also provided with a hole (14) that communicates with the heat power supply chamber (8); a plug (5) is set inside the hole (14); a heat power supply cavity wrap (4) is applied on the external surface of the shielding cavity (3); one end-face of the mini thermoelectric power generator (2) applies with interior surface of the outer housing (1); the other end-face of the mini thermoelectric power generator (2) applies with external surface of the heat power supply cavity wrap (4); output wire (9) that connected to the output conductive junction point of the mini thermoelectric power generator is set outside of the whole body of the thermoelectric power supply. The radioactive isotope mini thermoelectric power supply is provided with convenient usage, long service life and environmental protection.

Description

technical field [0001] The invention relates to the field of miniature thermoelectric power sources, in particular to a radioisotope miniature thermoelectric power source. Background technique [0002] With the rapid development of micro-electro-mechanical systems (MEMS) technology, micro-sensors, ultra-micro-motors, micro-aircraft and flexible pipeline robots for diagnosis have been gradually popularized and applied, although many functional components of micro-electro-mechanical systems (MEMS) devices, Such as micro-sensors, micro-actuators, micro-pumps, micro-valves, etc., their volume can be made very small, but most of the power sources that provide energy for micro-electro-mechanical system (MEMS) devices are powered by external cables, which is very important for the entire micro-electro-mechanical system. Some are bulky and inconvenient to use; some are powered by chemical batteries, which have a short service life and are not environmentally friendly. Contents of ...
