Kev txiav txim siab ntawm cov cua kub dissipation ntawm photovoltaic panels
Kev lag luam tam sim no kev sib tham txog lub zog tau dhau los ua kev vam meej. Nws tau dhau los ua qhov tseeb tias kuv lub teb chaws lub zog qauv yog qhov tsis tsim nyog. Ze li 70% ntawm lub zog siv txhua xyoo yog cov thee nyoos. Cov qauv hluav taws xob tswj hwm los ntawm cov thee nyoos yog khi ua rau muaj ntau cov pa roj carbon dioxide emissions thiab ua rau muaj kuab paug ib puag ncig. Ua rau kev puas tsuaj ecological, qhov xwm txheej tam sim no tseem muaj zog ntxiv.
Lub zog tauj dua tshiab uas sawv cev los ntawm lub hnub ci zog tau nyiam ntau thiab ntau dua. Hnub ci zog yog nyob deb ntawm ntau tshaj, inexhaustible, inexhaustible thiab cleanest renewable zog. Ntawm ntau lub zog tauj dua tshiab siv thev naus laus zis, photovoltaic vaj huam sib luag hluav taws xob tsim tshuab yog ib txoj hauv kev zoo tshaj plaws.
Tsuas yog 5% mus rau 25% ntawm lub hnub ci hluav taws xob absorbed los ntawm photovoltaic panels yog hloov mus rau hauv hluav taws xob lub zog, thiab qhov seem uas siv tsis tau yog hloov dua siab tshiab rau hauv lub zog hluav taws xob. Lub photoelectric efficiency ntawm photovoltaic panels yog cuam tshuam los ntawm qhov kub thiab txias. Thaum qhov kub thiab txias tshaj 25 ° C nyob rau hauv lub hnub ci ntawm 1000W / m2, lub photoelectric efficiency yuav txo los ntawm 0.4% -0.5% rau txhua txhua 1 degree nce.
Yog li ntawd, kev tshawb fawb txog yuav ua li cas kom txo tau cov hluav taws kub ntawm photovoltaic panels, txo qhov kub thiab txias ntawm photovoltaic panels, thiab txhim kho lub photoelectric conversion efficiency ntawm photovoltaic panels yog ib qho tseem ceeb heev nyob rau hauv kev soj ntsuam nrog depletion ntawm tsoos fossil zog thiab ib puag ncig muaj kuab paug.
Photovoltaic vaj huam sib luag cua sov dissipation tshuab siv cov txheej txheem sab nraud kom dissipate tshav kub thaum qhov kub thiab txias ntawm lub vaj huam sib luag photovoltaic siab dhau lawm, kom qhov kub thiab txias ntawm lub vaj huam sib luag photovoltaic khaws cia rau hauv qhov ntsuas kub uas tsim nyog, yog li txhim kho qhov kev hloov pauv ntawm photoelectric efficiency ntawm photovoltaic. vaj huam sib luag. Thaum tshav kub kub dissipation tshuab txiav txim siab cov kev cai hauv qab no:
1) Ua kom zoo txo qhov kub thiab txias, txhim kho kev ua haujlwm ntawm photovoltaic panels, thiab muaj qhov kub zoo sib xws.
2) Cov qauv yooj yim, ua haujlwm yooj yim, tus nqi qis thiab kev saib xyuas yooj yim.
Tam sim no, muaj peb lub thev naus laus zis: cua kub dissipation, cua sov yeeb nkab cua sov dissipation, thiab cov khoom cua kub dissipation (composite theem hloov cov ntaub ntawv nrog cov ntaub ntawv txhim kho).
Cua txias
Nta
Cov cua sov tsim tawm ntawm qhov chaw ntawm lub vaj huam sib luag photovoltaic raug tshem tawm los ntawm huab cua convection, thiab cov txheej txheem kev ua haujlwm no yooj yim hauv cov qauv, tsis tshua muaj nqi, thiab yooj yim rau kev khiav lag luam. Raws li seb cov huab cua convection ntws tau los yog artificially, nws muaj peev xwm muab faib ua tej yam ntuj tso convection thiab yuam convection. Natural convection txhais tau hais tias tsuas yog qhov sib txawv hauv zos qhov sib txawv ntawm qhov sib txawv ntawm qhov kub thiab txias ntawm huab cua nws tus kheej thiab qhov chaw ntawm lub vaj huam sib luag photovoltaic yog siv rau kev khiav thiab kev sib hloov cua sov. Cov cua sov ntawm qhov chaw ntawm lub vaj huam sib luag photovoltaic yog spontaneously pauv mus rau saum huab cua, thiab cov kiv cua hluav taws xob los yog kiv cua tuaj yeem siv los quab yuam huab cua.Flow rau cua sov dissipation thiab txias.
Ua tsis tau
Txawm hais tias huab cua kub dissipation tshuab muaj qhov zoo ntawm cov qauv yooj yim thiab tus nqi qis, cov cua thermal conductivity tsawg thiab nws yooj yim cuam tshuam los ntawm ib puag ncig sab nraud. Yog li ntawd, cov tshuab hluav taws xob tshiab yog xav tau los daws cov teeb meem uas twb muaj lawm.
Thaum tshav kub kub cov yeeb nkab txias
Nta
Thaum tshav kub kub cov yeeb nkab kub dissipation muaj ib tug zoo dua tshav kub dissipation nyhuv tshaj cua kub dissipation. Thaum tshav kub kub cov yeeb nkab kub dissipation txhim kho cov khoom siv ntxiv, xws li cov twj tso kua mis, cov kav dej kub thiab kev tswj xyuas. Photovoltaic vaj huam sib luag / cov yeeb nkab kub cua kub dissipation tshuab siv cov yeeb nkab thermal conductivity thiab cov kua nruab nrab kub dissipation, uas tuaj yeem yog ib txoj kev tshav kub dissipation uas sai absorbs lub tshav kub generated los ntawm photovoltaic panels thiab sau cov cua sov rau siv.
Ua tsis tau
Txawm hais tias cov khoom siv hluav taws xob hluav taws xob kub dissipation tuaj yeem txo qhov kub ntawm qhov chaw ntawm photovoltaic panels, nws muaj qhov tsis zoo ntawm cov thermal conductivity thiab latent cua sov ntawm cov kua dej dav dav, thiab cov qauv ntawm tag nrho cov cua kub dissipation system, kev saib xyuas nyuaj, thiab tus nqi siab.
