Uburyo bwo guhitamo modules zo gukonjesha za thermoelectric zifite ibyiciro byinshi (modules za peltier nyinshi)

Guhitamo modules zo gukonjesha thermoelectric zifite ibyiciro byinshi (Multi-stage peltier device) biragoye cyane kuruta guhitamo modules zisanzwe za thermoelectric zifite icyiciro kimwe, peltier cooler kuko zirimo imiterere ya "cascade" kandi zifite ibisabwa byinshi mu gucunga ubushyuhe no guhuza imiterere y'amashanyarazi.

Intambwe ya 1: Sobanura ibisabwa by'ingenzi (imiterere y'ibyinjira)

Mbere yo kureba moderi runaka, "ibipimo bikomeye" bitatu bikurikira bigomba kugenwa uko bigize ishingiro ry'ihitamo:

Ubushyuhe bw'intego (Tc) n'ubushyuhe bw'inyongera (Th):

Ubushyuhe bugomba kugera ku ki? (Urugero: -40°C)

Ni ubuhe bushobozi ntarengwa bwo gukwirakwiza ubushyuhe bw'igice gishyushye? (Ubusanzwe gikozwe nka 25°C cyangwa 50°C).

Kubara itandukaniro ry'ubushyuhe (ΔT): ΔT = Th – Tc. Udupira twinshi dukoreshwa mu bihe bitandukanye aho ΔT > 70°C.

Umutwaro w'ubushyuhe (Qc):

Igikoresho gikonjeshwa gitanga wattage ingana iki (W)?

Iyo utabizi neza, ni ngombwa kubara ubushyuhe bwose butangwa n'ikintu, harimo ubushyuhe bw'imbere, ubushyuhe bwo gutwara ibintu, n'ubushyuhe bw'imirasire.

Umwanya n'amashanyarazi bihari:

Ibipimo by'ingano y'iyinjizwa (uburebure n'ubugari)?

Ese ni voltage idahinduka y'amashanyarazi (nka 12V, 24V) cyangwa voltage idahinduka y'amashanyarazi? Ni iyihe ntarengwa ntarengwa y'amashanyarazi?

Intambwe ya 2: Sobanukirwa ibipimo by'ingenzi (ibipimo by'ingenzi)

Ibipimo bya modules za peltier zifite ibyiciro byinshi, ibikoresho bya pletier bifite ibyiciro byinshi bifitanye isano ikomeye. Ibande kuri ibi bine bikurikira:

Umubare w'intambwe (Intambwe):

Iki ni cyo kintu kiranga cyane modules za thermoelectric zifite ibyiciro byinshi, ibintu bya peltier. Ubusanzwe, hari ibyiciro 2, ibyiciro 3, cyangwa se ibyiciro 6 bya module ya thermoelectric cooling.

Itegeko rigenga: Uko ibyiciro byinshi, ni ko itandukaniro ry'ubushyuhe rishobora kugerwaho rirushaho kuba rinini, ariko ubushobozi bwo gukonjesha (Qc) buzaba buto kandi igiciro kizaba kinini. Muri rusange, itandukaniro ntarengwa ry'ubushyuhe bw'icyiciro kimwe ni hafi 60-70°C. Niba ubushyuhe bwa -80°C cyangwa munsi yabwo bukenewe, hagomba gutoranywa module ya peltier y'icyiciro kinini.

Ubushobozi ntarengwa bwo gukonjesha (Qmax):

Bivuga ubushobozi ntarengwa bwo kwinjiza ubushyuhe iyo itandukaniro ry'ubushyuhe ari 0.

Igitekerezo cyo guhitamo: Ubushobozi nyabwo bwo gukonjesha (Qc) mu gihe cyo gukora ni buto cyane ugereranije na Qmax. Muri rusange, ni byiza ko Qmax ikwiye kuba inshuro 1.3 kugeza kuri 2 z'umutwaro w'ubushyuhe bwawe, bigatuma habaho imikorere myiza n'igihe kirekire.

Itandukaniro ntarengwa ry'ubushyuhe (ΔTmax):

Bivuga itandukaniro rikomeye ry'ubushyuhe module ya thermoelectric cooling element, peltier element, ishobora kugeraho (iyo ubushobozi bwo gukonjesha ari 0).

Igitekerezo cyo guhitamo: ΔTmax yatoranijwe igomba kuba iri hejuru ya 10-20% ugereranyije n'itandukaniro nyaryo ry'ubushyuhe ukeneye.

Voltage n'amashanyarazi (Vmax / Imax):

Ubudahangarwa bw'imbere bwa module ya thermoelectric cooling module ifite ibyiciro byinshi, module ya TEC ubusanzwe ni nini, kandi voltage ishobora kuba iri hejuru (nka 24V, 48V, cyangwa irenga), mu gihe umuriro ari muto ugereranije. Menya neza ko umuriro wawe ushobora kuwukoresha.

Intambwe ya 3: Koresha umurongo w'imikorere (guhuza neza)

Iyi ni intambwe y'ingenzi cyane. Ntukishingikirize gusa ku gaciro ntarengwa kavuzwe ku rupapuro rw'ibisobanuro!

Imikorere ya module ya thermoelectric cooling module ifite ibyiciro byinshi ntabwo ari umurongo umwe.

Menya aho imikorere ibera: Ku itandukaniro ry'ubushyuhe bw'intego yawe (ΔT) n'ubushobozi bwo gukonjesha intego (Qc), reba imbonerahamwe y'umurongo ugororotse.

Shaka umuvuduko mwiza (Iop): Shaka agaciro k'umuvuduko ujyanye.

Kubara igipimo cy’ingufu zikoreshwa neza (COP): Gerageza gukora module ya thermoelectric ikora mu karere gafite COP iri hejuru (ubusanzwe hafi 30%-50% by’umuvuduko ntarengwa), aho gukora ku muvuduko wuzuye. Gukora ku muvuduko wuzuye bishobora gutanga ubukonje bwihuse, ariko bitanga ubushyuhe bwinshi kandi bigira umusaruro muke cyane.

Intambwe ya 4: Imiterere n'Imiterere

Modules zo gukonjesha thermoelectric zikoresha ibyiciro byinshi (modules za TEC zikoresha ibyiciro byinshi) zirakomeye kurusha modules zo gukonjesha thermoelectric zikoresha ibyiciro bimwe (modules za peltier zikoresha ibyiciro bimwe). Mu guhitamo ubwoko, imiterere y'umubiri igomba kwitabwaho:

Ingano mbi:

Muri rusange, modules zo gukonjesha za peltier zifite ibyiciro byinshi ntizisabwa gukorwa nini cyane (nk'inini rirenze mm 62x62), kuko ahantu hanini cyane hashobora gutuma plaque za ceramic zigorama cyangwa zicika. Ku gukonjesha kw'ikirere kinini, ni byiza gukoresha modules nyinshi nto za peltier zihujwe mu buryo bungana cyangwa bukurikiranye.

Uburyo bwo guhuza:

Guhuza umurongo: Bisabwa. Umuyoboro w'amashanyarazi urahoraho, byoroshye kugenzura. Iyo igice kimwe cyangiritse, gishobora kugaragara byoroshye (niba hari aho umuyoboro w'amashanyarazi wacitse).

Guhuza ibintu mu buryo bungana: Ntibyemewe. Iyo imbaraga z'imbere z'igice kimwe zihindutse, uburyo ubushyuhe bukwirakwiramo buzagabanuka, bigatera "irushanwa ririho ubu", bikongera kwangirika.
