Phello ea thermoelectric ea sensor

Lisebelisoa tsa semiconductor li na le matla a phahameng a thermoelectric 'me li ka sebelisoa ka katleho ho etsa lihatsetsi tse nyenyane tsa thermoelectric.Setšoantšo sa 1 se bontša ntho ea sehatsetsing sa thermocouple e entsoeng ka semiconductor ea mofuta oa n le semiconductor ea mofuta oa p.Semiconductor ea mofuta oa N le semiconductor ea mofuta oa P li hokahane ka seketsoana ka lipoleiti tsa koporo le lithapo tsa koporo, 'me lipoleiti tsa koporo le lithapo tsa koporo li phetha karolo ea conductive feela.Nakong ena, puisano e le 'ngoe ea chesa' me e 'ngoe ea bata.Haeba tataiso ea hona joale e khutlisetsoa morao, ketso e batang le e chesang sebakeng sa node e fetoha.

Sephetho sa sehatsetsi sa thermoelectric hangata se nyane haholo, ka hona ha sea lokela ho sebelisoa ka bongata le bo boholo.Leha ho le joalo, ka lebaka la ho feto-fetoha ha eona ho matla, bonolo le bonolo, e loketse haholo bakeng sa tšimo ea micro-refrigeration kapa libaka tse batang tse nang le litlhoko tse khethehileng.

Motheo oa theoretical oa sehatsetsi sa thermoelectric ke phello ea thermoelectric ea solid.Ha ho se na matla a khoheli a kantle, a kenyelletsa litlamorao tse hlano, e leng conduction ea mocheso, tahlehelo ea mocheso oa Joule, phello ea Seebeck, phello ea Peltire le phello ea Thomson.

Li-air conditioner le lihatsetsi tse akaretsang li sebelisa fluoride chloride e le sehatsetsi, e leng se etsang hore lera la ozone le senyehe.Ka hona, lihatsetsi tse se nang lihatsetsi (li-conditioner) ke ntlha ea bohlokoa ho sireletsa tikoloho.Ho sebelisa phello ea thermoelectric ea li-semiconductors, sehatsetsi se se nang sehatsetsi se ka etsoa.

Mokhoa ona oa ho hlahisa matla o fetola ka ho toba matla a mocheso hore e be matla a motlakase, 'me katleho ea eona ea ho fetola e lekanyelitsoe ke Carnotefficiency, molao oa bobeli oa thermodynamics.Khale koana ka 1822, Xibe o ile a e fumana, kahoo phello ea thermoelectric e boetse e bitsoa Seebeckeffect.

Ha e amane feela le mocheso oa li-junctions tse peli, empa hape le thepa ea li-conductor tse sebelisoang.Molemo oa mokhoa ona oa ho hlahisa matla ke hore ha o na likarolo tsa mochine o potolohang 'me o ke ke oa apara, kahoo o ka sebelisoa nako e telele.Leha ho le joalo, ho finyella katleho e phahameng, mohloli oa mocheso o nang le mocheso o phahameng oa hlokahala, 'me ka linako tse ling likarolo tse' maloa tsa lintho tsa thermoelectric lia phalla kapa li etsoa sethaleng ho finyella katleho e phahameng.
