Thermoelectric sanyaya kayayyaki aikace-aikace
Tushen samfurin aikace-aikacen sanyaya thermoelectric shine ma'aunin sanyaya thermoelectric. Dangane da halaye, rauni da kewayon aikace-aikace na tari na thermoelectric, ya kamata a ƙayyade matsalolin masu zuwa yayin zaɓar tari:
1. Ƙayyade yanayin aiki na abubuwan sanyaya thermoelectric. Bisa ga shugabanci da girman da aiki halin yanzu, za ka iya ƙayyade sanyaya, dumama da kuma yawan zafin jiki yi na reactor, ko da yake mafi yawan amfani da shi ne sanyaya hanya, amma kada ku yi watsi da dumama da kuma akai zazzabi yi.
2, Ƙayyade ainihin zafin jiki na ƙarshen zafi lokacin sanyaya. Saboda reactor shine na'urar bambancin zafin jiki, don cimma sakamako mafi kyau na sanyaya, dole ne a shigar da reactor akan mai kyau radiator, gwargwadon yanayin yanayin zafi mai kyau ko mara kyau, ƙayyade ainihin zafin jiki na ƙarshen thermal na reactor lokacin sanyaya, ya kamata a lura cewa saboda tasirin yanayin zafin jiki, ainihin zafin jiki na ƙarshen thermal na reactor koyaushe yana da ƙasa da ƙasa fiye da digiri na goma, mafi yawan zafin jiki na ƙasa fiye da matsakaicin matsakaiciyar ƙasa. fiye da 'yan digiri, goma digiri. Hakazalika, ban da raɗaɗin zafin zafi a ƙarshen zafi, akwai kuma yanayin zafi tsakanin wurin sanyaya da ƙarshen sanyi na reactor.
3, Ƙayyade yanayin aiki da yanayi na reactor. Wannan ya haɗa da ko kayan aikin TEC, na'urorin sanyaya thermoelectric don yin aiki a cikin sarari ko a cikin yanayi na yau da kullun, busassun nitrogen, a tsaye ko iska mai motsi da yanayin zafi, daga abin da ake ɗaukar matakan thermal insulation (adiabatic) kuma an ƙaddara tasirin zubar zafi.
4. Ƙayyade kayan aiki na abubuwan thermoelectric da girman nauyin thermal. Bugu da ƙari ga tasirin yanayin zafi na ƙarshen zafi, ƙananan zafin jiki ko matsakaicin matsakaicin zafin jiki wanda abubuwan TEC N, P zasu iya cimma an ƙayyade a ƙarƙashin yanayi biyu na babu-load da adiabatic, a gaskiya ma, abubuwan peltier N, P ba za su iya zama ainihin adiabatic ba, amma kuma dole ne su sami nauyin thermal, in ba haka ba yana da ma'ana.
5. Ƙayyade matakin thermoelectric module, TEC module (peltier abubuwa). Zaɓin jerin reactor dole ne ya cika buƙatun ainihin bambance-bambancen zafin jiki, wato, bambancin zafin jiki na ma'aunin zafin jiki dole ne ya kasance sama da ainihin bambance-bambancen zazzabi da ake buƙata, in ba haka ba ba zai iya cika buƙatun ba, amma jerin ba zai iya zama da yawa ba, saboda farashin reactor yana haɓaka sosai tare da haɓakar jerin.
6. Ƙayyadaddun abubuwan da ake amfani da su na thermoelectric N, P. Bayan an zaɓi jerin nau'in na'urar peltier N, P, za a iya zaɓar ƙayyadaddun abubuwan peltier N, P, musamman ma aiki na yanzu na mai sanyaya N, P abubuwan. Domin akwai nau'o'in reactor da yawa waɗanda zasu iya saduwa da bambancin zafin jiki da samar da sanyi a lokaci guda, amma saboda yanayin aiki daban-daban, yawanci ana zaɓar reactor tare da mafi ƙarancin aiki na yanzu, saboda farashin wutar lantarki kaɗan ne a wannan lokacin, amma jimlar ikon reactor shine ƙayyadaddun factor, ƙarfin shigarwa iri ɗaya don rage yawan aiki na yanzu yana da haɓaka ƙarfin lantarki (0.1v a kowace logarith na abubuwan haɗin gwiwa).
7. Ƙayyade adadin abubuwan N,P. Wannan ya dogara ne akan jimlar ƙarfin sanyaya na reactor don saduwa da buƙatun bambancin zafin jiki, dole ne a tabbatar da cewa jimlar ƙarfin sanyaya wutar lantarki a yanayin zafin aiki ya fi ƙarfin ƙarfin thermal na kayan aiki, in ba haka ba ba zai iya biyan buƙatun ba. Thermal inertia na tari yana da ƙananan ƙananan, ba fiye da minti daya ba a karkashin babu kaya, amma saboda rashin aiki na kaya (yafi saboda ƙarfin zafi na kaya), ainihin saurin aiki don isa ga yanayin zafin jiki yana da girma fiye da minti daya, kuma idan dai har tsawon sa'o'i da yawa. Idan buƙatun saurin aiki sun fi girma, adadin tara zai fi yawa, jimlar ƙarfin ƙarfin zafi ya ƙunshi jimlar ƙarfin zafi tare da ɗigon zafi (ƙananan zafin jiki, mafi girman zubar zafi).
Abubuwan da ke sama sune manyan ka'idodin da za a yi la'akari da su yayin zabar kayan aikin thermoelectric N, P peltier, bisa ga abin da mai amfani na asali yakamata ya fara zaɓar na'urorin sanyaya thermoelectric, peltier cooler, TEC module bisa ga buƙatu.
(1) Tabbatar da amfani da yanayin zafin jiki Th ℃
(2) Ƙananan zafin jiki Tc ℃ ya kai ta wurin sanyaya sarari ko abu
(3) Sanannen kaya mai zafi Q (ƙarfin zafi Qp, zubar zafi Qt) W
An ba da Th, Tc da Q, abubuwan da ake buƙata Thermoelectric mai sanyaya N, P abubuwan da adadin abubuwan TEC N, P za a iya ƙididdige su gwargwadon yanayin yanayin yanayin sanyi na thermoelectric, mai sanyaya peltier, samfuran TEC.
