Thermoelectric type micro power supply unit based on cold-heat source balance

Abstract

The invention discloses a thermoelectric microtype power supply device based on cold-hot source balance, namely a cylinder formed by in turn superposing and fixing covered container with cold storage material, thermoelectric converter, isolating cover and combustion table as well as hollow base, where the isolating cover is of an inverted cup shape, the cup mouth is arranged with tooth slots and the combustion table is a cylinder with interlayer inside, the vertical section of the combustion is H-shaped, the central interlayer has hole, a lampwick is arranged in the hole, one end of the lampwick is placed in the base cavity, the circular wall on the top of the combustion table has tooth slots, the isolating cover is covered on the top circle, the middle cavity forms a combustion chamber, the tooth walls of the isolating cover and the combustion table closely slide, and the slot mouths compose gas inlet of the combustion chamber. During using course, it uses the high-temperature heat generated by liquid fuel as heat source, and cold storage material cooled by low temperature object, generates temperature difference electromotive force on two surfaces of the thermoelectric converter, and thus obtains electric energy. The power supply is small-bulk, and able to be widely applied to high, exact and sophisticated technical fields of field and military affairs, etc.

Description

technical field [0001] The invention relates to a device for generating electricity by using temperature difference, in particular to a thermoelectric micro power supply device based on the balance of cold and heat sources. Background technique [0002] According to the Seibel effect, when there is a temperature difference between the two sides of the thermoelectric conversion sheet, a thermoelectric electromotive force can be generated. The thermoelectric power supply device is a device that uses the temperature difference to generate electricity. At present, devices that use thermoelectric conversion sheets to achieve thermoelectric conversion have no source of temperature difference, and can only rely on external temperature differences, such as warm water pipes, solar radiation, etc., the output power per unit volume is small, and there are limitations in the place of use. Contents of the invention [0003] The object of the present invention is to provide a thermoelec...
