Cov keeb kwm ntawm hnub ci thermal daim ntawv thov yog ntev dua li cov ntawv thov photovoltaic, kev lag luam hnub ci dej rhaub dej tau tshwm sim hauv 1891 hnub ci thermal daim ntawv thov yog los ntawm kev nqus ntawm lub hnub ci, lub teeb lub zog rau hauv thermal zog tom qab siv ncaj qha los yog cia tuaj yeem hloov mus rau hauv hluav taws xob los ntawm kev siv hluav taws xob ua hluav taws xob. Hnub ci kev siv hluav taws xob tuaj yeem muab faib ua peb pawg raws li qhov kub thiab txias: daim ntawv thov kub qis (<100C), feem ntau yog siv rau hauv pas dej da dej cua sov, cua cua preheating, thiab lwm yam. Cov ntawv thov kub kub (> 400C), feem ntau yog siv rau kev lag luam cua sov, thermal zog tsim, thiab lwm yam.
Nyias zaj duab xis thev naus laus zis kuj tseem ua lub luag haujlwm tseem ceeb hauv kev siv hnub ci thermal. Vim lub hnub ci zog tsawg ntawm qhov chaw (kwv yees li 1kW / m² thaum nruab hnub, cov neeg siv khoom xav tau thaj chaw loj los sau lub hnub ci zog. Qhov loj / tuab piv ntawm hnub ci photothermal zaj duab xis ua rau cov yeeb yaj kiab uas raug rau kev laus, uas cuam tshuam rau lub neej ntawm cov khoom siv hnub ci photothermal. Cov kev cai tseem ceeb rau hnub ci thermal kev lag luam yog peb lub neej ntev. Kev ntsuas lub zog ntawm lub hnub ci thermal zaj duab xis zoo yuav tsum muaj kev nqus zoo tshaj plaws ntawm ntau lub hnub ci hluav taws xob thiab qis thermal emissivity a / e coefficient yog siv los ntsuas qhov spectral selectivity ntawm zaj duab xis, qhov twg yog lub hnub ci absorptivity thiab e stands rau thermal emissivity ntawm lub pob ntseg sib txawv cov txheej dub ntawm cov ntawv hlau, uas ploj mus txog li 45 feem pua ntawm cov hluav taws xob ntev-ntev tawm thaum nws nqus cov cua sov thiab sov so, ua rau lub hnub ci hluav taws xob khaws cia tsuas yog 50 feem pua Qhov kev ua tau zoo ntawm cov yeeb yaj kiab photothermal tuaj yeem txhim kho tau zoo los ntawm kev siv spectrally xaiv nyias-zaj duab xis cov ntaub ntawv xws li platinum hlau los yog chromium Feem ntau yog npaj los ntawm CVD los yog magnetron sputtering, thiab cov thermal emissivity yuav raug txo kom tsawg li 15 feem pua rau cov yeeb yaj kiab nrog cov khoom siv hluav taws xob txog li 80 feem pua Qhov zoo tshaj plaws spectrally selective collector films muaj qhov nqus coefficient ntawm ntau dua 0.98 nyob rau hauv lub ntsiab bands ntawm lub hnub ci spectrum tsawg dua 0.0. 500C thermal radiation band (> 3um), thiab muaj cov qauv thiab kev ua haujlwm ruaj khov ntawm 500 ° C hauv huab cua.
