3.2 Cov ntawv thov rau cov khoom siv hluav taws xob muaj xws li:
- avionics.
- Blackbox txias.
- calorimeters.
- CCD (Cov Khoom Siv Hluav Taws Xob Hluav Taws Xob)
- CID (Chaw Induced Devices)
- Cold chambers.
- daim phiaj txias.
- Compact heat exchangers.
Dab tsi yog daim ntawv thov tseem ceeb ntawm thermoelectric?
Lub zog thermoelectric muaj ntau yam kev siv hauv ntau yam xws li; hluav taws xob tsim, tub yees, cua txias, tshwj xeeb cua sov / cua txias, biomedical devicesthiab lwm yam vim nws txoj kev tsim kho yooj yim thiab kev siv tshuab, txav tau yooj yim, xav tau DC cov khoom siv khiav thiab lwm yam.
Cov piv txwv ntawm cov khoom siv hluav taws xob yog dab tsi?
Cov khoom siv thermoelectric
- Bismuth telluride (Bi2Te3) Alloy. Nws yog ib tug semiconductor, uas muaj hluav taws xob conductivity, tab sis nws tsis zoo ntawm hloov tshav kub. …
- Lead Telluride (PbTe) Alloy. Nws muaj qhov melting point ntawm 905 ℃. …
- Silicon-Germanium Alloy.
Thermoelectric zog siv rau dab tsi?
Thermoelectric lub tshuab hluav taws xob, ib qho ntawm cov khoom siv hauv lub xeev uas hloov cov cua sov ncaj qha mus rau hauv hluav taws xob lossis hloov pauv hluav taws xob rau hauv thermal fais fab rau cua sov lossis cua txias.
Cov cuab yeej siv hluav taws xob ua haujlwm li cas?
Thermoelectric generators (TEG) yog cov khoom siv hluav taws xob hauv lub xeev cov khoom siv uas hloov pauv ibQhov sib txawv ntawm qhov kub thiab txias ntws mus rau hauv qhov muaj txiaj ntsig DC fais fab. Thermoelectric generator semiconductor li siv cov nyhuv Seebeck los ua kom muaj zog. … Nrog rau qhov kev tshwm sim no, cua sov tau txav ntawm sab txias mus rau sab kub.

Usability engineering yog kev qhuab qhia uas tsom mus rau kev txhim kho kev siv tau ntawm kev sib tham sib. Nws rub tawm cov kev xav los ntawm kev tshawb fawb hauv computer thiab kev puas siab puas ntsws los txhais cov teeb meem uas tshwm sim thaum siv cov kab ke.
Puas siv hluav taws xob hauv qhov hluav taws xob tuaj yeem siv rau ntawm qhov loj?
Txawm hais tias tsawg dua, lwm hom kev siv hluav taws xob hauv av tuaj yeem siv los muab ntau lub zog ntau dua. Tapping qhov chaw ntawm cov dej kub faus rau hauv qab lub ntiaj teb saum npoo tuaj yeem muab cua sov rau cov neeg coob coob, thiab tsim kom muaj zog txaus los tsim hluav taws xob loj.
Hauv cov khoom siv hluav taws xob tsim hluav taws xob?
Nyob hauv cov khoom siv hluav taws xob tsim hluav taws xob, xws li hlau, hluav taws xob rhaub, boiler, toaster thiab lwm yam, ib qho hlau xws li Nichrome Nichrome Nichrome (tseem hu ua NiCr, nickel-chromium lossis chromium-nickel) yog ib tsev neeg ntawm cov alloys ntawm npib tsib xee, chromium, thiab feem ntau hlau (thiab tejzaum nws muaj lwm yam) feem ntau siv raws li cov hlau tsis kam, cov khoom cua sov hauv cov khoom xws li toasters thiab qhov chaw tso cua sov, hauv qee qhov
Puas hluav taws xob hluav taws xob puas tsim hluav taws xob?
Coal feem ntau siv roj los tsim hluav taws xobhauv Tebchaws Meskas. Hauv cov chaw tsim hluav taws xob hluav taws xob hluav taws xob, cov hluav taws xob bituminous, subbituminous thee, lossis lignite raug hlawv. Cov cua kub uas tsim los ntawm kev sib xyaw ntawm cov thee yog siv los hloov cov dej mus rau hauv qhov chaw siab zog, uas tsav lub turbine, uas tsim hluav taws xob.
Lub tshuab hluav taws xob hluav taws xob tsim hluav taws xob li cas?
Piav seb lub twj hluav taws xob hluav taws xob tsim hluav taws xob hla lub membrane li cas. Los ntawm pum electrons hla lub membrane, sab uas cov electrons raug tshem tawm muaj qhov zoo dua, thaum sab tau txais cov hluav taws xob ntau muaj qhov tsis zoo.
