Thermoelectric power generation structure and temperature measuring sensor
View Patent ↗This application discloses a thermoelectric power generation structure and a temperature measuring sensor. The thermoelectric power generation structure includes: a semiconductor power generation element, a first thermal-conductive element arranged in a first environment and connected to an inner side face of the semiconductor power generation element, and a second thermal-conductive element connected to an outer side face of the semiconductor power generation element. When there is a temperature difference between the first environment and the second environment, the semiconductor power generation element generates electric power. This application solves the technical problem that the thermoelectric power generation structure cannot match a sensor probe and fails to create a thermoelectric power generation environment, and accordingly cannot effectively generate electric power to the sensor probe in an enclosed high-temperature food heating scene.
