Basic txoj kev xav ntawm infrared rhaub cua sov hloov
Cov cua sov infrared tau dhau los ua qhov nrov ua cua sov rau ntau yam kev lag luam, kev lag luam, thiab kev siv hauv tsev. Cov cua sov no ua haujlwm los ntawm emitting infrared hluav taws xob, uas yog absorbed los ntawm cov khoom thiab qhov chaw nyob ib puag ncig, thiab tom qab ntawd hloov mus rau hauv tshav kub. Lub hauv paus txoj kev xav ntawm infrared rhaub cua sov hloov pauv nyob ib ncig ntawm peb lub ntsiab lus tseem ceeb: hluav taws xob, nqus, thiab kev xav.
Hluav taws xob
Radiation yog tus txheej txheem uas lub zog tawm hauv daim ntawv ntawm electromagnetic tsis. Infrared heaters tsim hluav taws xob nyob rau hauv cheeb tsam infrared ntawm lub electromagnetic spectrum, uas muaj ib tug wavelength ntau yam ntawm 0.7 mus rau 1000 microns. Cov hluav taws xob tso tawm los ntawm lub tshuab hluav taws xob infrared yog absorbed los ntawm cov khoom thiab qhov chaw hauv nws txoj kev, uas ua rau kev hloov ntawm tshav kub.
Kev nqus
Absorption yog txheej txheem uas lub zog nqa los ntawm hluav taws xob xa mus rau ib qho khoom lossis qhov chaw. Qhov nqus ntawm qhov nqus yog nyob ntawm cov khoom siv ntawm cov khoom lossis qhov chaw, xws li xim, kev ntxhib los mos, thiab emissivity. Cov khoom thiab qhov chaw uas muaj emissivity siab nqus tau hluav taws xob ntau dua li cov uas tsis muaj emissivity, uas ua rau muaj kev hloov pauv ntawm tshav kub ntau dua.
Kev xav
Reflection yog cov txheej txheem uas cov hluav taws xob rov qab los ntawm qhov chaw yam tsis tau absorbed. Qhov ntev ntawm kev xav yog nyob ntawm cov khoom siv ntawm qhov chaw, xws li smoothness thiab reflectivity. Qhov chaw uas muaj kev cuam tshuam siab cuam tshuam ntau dua cov hluav taws xob ntau dua li cov uas tsis tshua muaj kev cuam tshuam, ua rau muaj kev hloov hluav taws xob tsawg dua.
Hauv cov ntsiab lus, txoj kev xav ntawm lub tshuab hluav taws xob hloov hluav taws xob hloov hluav taws xob muaj xws li emission ntawm hluav taws xob, nqus hluav taws xob los ntawm cov khoom thiab qhov chaw nrog cov emissivity siab, thiab qhov cuam tshuam ntawm hluav taws xob los ntawm cov chaw uas muaj kev cuam tshuam siab. Los ntawm kev nkag siab txog cov ntsiab lus no, nws muaj peev xwm tsim thiab ua haujlwm infrared cua sov kom pom kev ua haujlwm zoo thiab ua haujlwm zoo.
