Qhov sib txawv ntawm ntau theem thermoelectric txias modules (Multi-stage peltier devices) thiab ib-theem thermoelectric txias modules (peltier elements)

Qhov sib txawv ntawm ntau theem thermoelectric txias modules (Multi-stage peltier devices) thiab ib-theem thermoelectric txias modules (peltier elements)

Qhov sib txawv tseem ceeb ntawmCov ntsiab lus peltier ntau theem, cov khoom siv peltier thiab cov khoom siv peltier ib-theem, cov khoom siv peltier ib theem nyob rau hauv lawv cov qauv sab hauv, qhov kub qis tshaj plaws uas lawv tuaj yeem ncav cuag, thiab lawv cov xwm txheej siv. Hauv cov lus yooj yim, cov khoom siv peltier ntau theem yog tsim los ua kom tiav cov nyhuv txias tob uas cov modules peltier ib-theem tsis tuaj yeem.

Cov Qauv thiab Txoj Cai Ua Haujlwm

Ib-theem TEC modules, thermoelectric txias modules: Qhov no yog daim ntawv yooj yim tshaj plaws, muaj ib txheej ntawm P-hom thiab N-hom semiconductor cov ntaub ntawv. Thaum lub zog rau, nws siv Peltier nyhuv los hloov cua sov los ntawm ib sab (qhov kawg txias) mus rau sab tod (qhov kawg kub), ua tiav txias.

Cov khoom siv cua txias thermoelectric ntau theem, cov khoom siv cua txias peltier ntau theem: Nws tuaj yeem nkag siab tias yog ntau cov khoom siv TEC ib theem uas tau teeb tsa ua "kub series", feem ntau yog ua lub pyramid. Qhov kawg txias ntawm theem sab saud ua haujlwm ua qhov chaw cua sov rau qhov kawg kub ntawm theem qis dua. Los ntawm txoj kev "relay cooling" no, txhua theem txias ntxiv raws li theem dhau los, yog li ua tiav qhov txias tob.

Kev sib txawv ntawm kev ua tau zoo

Qhov sib txawv ntawm qhov kub siab tshaj plaws: Qhov no yog qhov sib txawv tseem ceeb tshaj plaws ntawm ob qho no.

Ib theem thermoelectric txias module, peltier txias: Qhov sib txawv ntawm qhov kub siab tshaj plaws feem ntau yog nyob ib puag ncig 60-70 ℃.

Cov khoom siv cua txias thermoelectric ntau theem, lub cuab yeej peltier: Los ntawm kev sib sau ua ke thiab kev teeb tsa, qhov sib txawv ntawm qhov kub tshaj 100 ℃ tuaj yeem ua tiav. Qee cov qauv tuaj yeem ncav cuag qhov kub qis heev hauv qab -100 ℃.

Lub peev xwm txias:

Lub tshuab cua txias peltier ib theem: Lub zog txias (Qmax) loj heev, ua rau nws tsim nyog rau kev tswj hwm cov cua sov loj.

Cov khoom siv peltier ntau theem: Vim nws cov qauv nyuaj thiab kev poob zog, nws lub peev xwm txias txo qis thaum tus lej ntawm cov theem nce ntxiv. Yog li ntawd, cov khoom siv thermoelectric ntau theem yog qhov tsim nyog rau "kub tsawg, txias tob".

Daim ntawv thov scenario

Ib theem thermoelectric module(Peltier cooler): Haum rau kev tso cua sov dav dav lossis txias nrog qhov kub tsawg, xws li lub tub yees me me, CPU coolers, lub thawv txias thiab sov hauv tsheb, thiab lwm yam.

Multi-stage thermoelectric module (TEC module): Tsim tshwj xeeb rau cov teb tshwj xeeb uas xav tau qhov kub qis heev, xws li:

Kev ua haujlwm hauv aerospace: Txias cov khoom siv infrared detectors, radiation spectrometers, thiab lwm yam, kom lawv ua haujlwm tau ntawm qhov kub qis heev kom txo tau suab nrov.

Kev Kho Mob: Ua haujlwm ua lub vijtsam txias rau cov khoom siv nuclear magnetic resonance (MRI) kom txo tau kev siv cov kua helium.

Cov cuab yeej siv tshawb fawb: Siv rau cov sensors tob hauv hiav txwv, cov khoom siv hauv chav kuaj mob siab, thiab lwm yam.
