Geothermal power generating device with thermoelectric generation element

Abstract

The invention discloses a geothermal power generating device with a thermoelectric generation element. The geothermal power generating device comprises a thermoelectric generation assembly including a thermoelectric generation sheet; a heat absorbing assembly formed by a second heat tube is installed at one side of a high temperature end of the thermoelectric generation sheet; and a heat radiation assembly formed by a first heat tube is installed at one side of a low temperature end of the thermoelectric generation sheet. Second heat-absorbing tube heat-absorbing fins are installed at a heat-absorbing end of the second heat tube; and a second heat-conducting converter sleeves a heat releasing end of the second heat tube. First heat tube heat-releasing fins are installed at heat absorbing and releasing ends of the first heat tube; and a first heat-conductive converter sleeves the heat absorbing end of the first heat tube. The second heat tube extends into a geothermal well; and a heat insulation tape and a plurality of intermediate heat exchange assemblies are arranged on the second heat tube. The thermoelectric generation sheet in the thermoelectric generation assembly provides power for a lamp outside the geothermal well by a lead. According to the invention, geothermal power generation can be realized simply and reliably; low heat losses during the long-distance transmission process can be guaranteed; and the power generation efficiency is high.

Description

technical field [0001] The invention belongs to the technical field of geothermal power generation, and in particular relates to a geothermal power generation device using a thermoelectric power generation element. Background technique [0002] At present, many places in China lack or even have no power supply for a long time. The difficulty of using power in these areas without electricity has become a problem that needs to be solved urgently. However, traditional power generation methods inevitably have mechanical transmission components, and the maintenance and operation costs of equipment are high. Less reliable. However, domestic equipment for long-distance heat transmission is not comprehensive, and a large amount of heat is dissipated to the external environment during long-distance transportation, which makes it difficult for many power generation equipment that rely on heat sources to improve their work due to limitations in actual conditions. efficiency.
