Radiation thermal

radiation emhlabeni (radiation) na ukutshintshwa kwamandla thermal ezibonelelwa amaza ukusuka umzimba omnye komnye. Oku kuvela ngenxa amandla yangaphakathi emzimbeni. Kulo mzekelo ubude yomtshangatshangiso isusela ukusuka micrometers 0,74 ukuya 1000. Amaza ukuba abe ubude ethile, ukuba zifunxwe ngumzimba izakhamzimba uze uwele emoyeni. Into enikisa umdla kukuba radiation ezinokwenzeka kuphela kwindawo ethile, kodwa cleaner. Le nkqubo ivelisa ubushushu - unit amandla.

radiation thermal lunokwenzeka ngenxa ekudibaneni kwemichiza okanye enyukliya kwelifu magnetic, kwakunye inyathelo ngoomatshini kwi into. Amandla akhutshwayo yosulela kwebala, oko kukuthi, intsebenziswano phakathi kwizifundo amaqondo aphezulu nezisezantsi, kwakunye ngokutshintshela ngokusebenzisa ulwelo okanye igesi okanye radiation (transfer ubushushu ukusuka kumthombo ukuya mbandela). Indlela yokugqibela ezihle kakhulu sinokwenziwa shushu. ray Ubushushu athwale amandla, yaye xa bafumane ngalo mbandela, le amandla ako - kwaye izinto ebushushwini babo. Xa izinto ezimbini kunye amaqondo ezahlukeneyo ezidibana kunye namanye, amiliswe yokumpompoza ubushushu, leyo uyayeka xa ubushushu bomzimba bafaniswa. Ngenxa yoko, i-radiation ubushushu kwenzeka. Le nkqubo kwenzeka kwindalo, umz, kwi emoyeni, yaye iindlela enziweyo, bathi isibane zigqengezelayo.

Kufuneka kuqatshelwe ukuba zonke umzimba udlala ukukhanya liqhawuke yaye ibizela ukukhanya nezinye imizimba. Kwimeko apho kukho lwesilinganiso thermal, kuba njengomlambo into nganye ukhutshiwe yaye wendele ngemitha iya kuba njalo. Kule meko sinakho ukuthetha malunga yokungabikho kweenkqubo exchange ubushushu phakathi iziqalelo. Xa amaqondo obushushu element mnye iphezulu ngaphezu enye, owayesakuba uya ziveza amandla thermal kangangoko ngaphezu ukukuqonda kwezinye emzimbeni. Apha uyakwazi ukuthetha phambi transfer ubushushu phakathi iziqalelo.

Qwalasela ukuba imitha ubushushu yena kunye neempawu zakhe.

Yinto eyaziwayo ukuba izinto lashushu lobushushu eliphezulu, zikhanyiswe. Le nto ibizwa kwimitha nje thermal. Lufezeke ngokushukumisa iimolekyuli ukwimo kokuba lobushushu ngentla zero. Ngenxa yoko, iqondo eliphezulu imitha mfutshane-wave ebonakalayo aphansi - infrared elide.

Cinga nje ngomzekelo lo mmangaliso. Ngoko ke, indawo yokuhlala kwiimeko ezininzi itshiswe kunye emitters ubushushu yombane. Xa lo mhlobo ebomvu a helices thermal kunye radiation ebonakalayo. Kwaye infrared nokushisa, nto leyo itshiswe kunye kwizakhiwo.

Ubushushu radiation - uhlobo wemitha lizama ukuba akukho ukutshintsha ongatshintshiyo iparameters. Zonke ezinye iintlobo kwemitha ezi non-kuvuselele.

Kakuhle eli zonke imisebe efanayo. Oku thaca ngokohlobo amaza zandise emajukujukwini. amandla emhlabeni ukhandwa odala amandla yangaphakathi ye element shushu. Inani le uhlobo lwamandla ixhomekeke lobushushu kunye neempawu ebonakalayo lomzimba, leyo ikhala.

radiation thermal kudlala indima ebalulekileyo kwiinkqubo zendalo kunye nemisebenzi yabantu. Ilanga kwi radiator elinamandla ubushushu. Ubunzulu radiation thermal nama-1.3 W / m2.

Ngenxa yoko, xa lwesilinganiso thermodynamic zoonke ndlela baye lobushushu efanayo. I-eneji ye-radiation thermal ezithi zivele nganye emzimbeni ihlawulelwa amandla leyo ifunxwe yi data emzimbeni. Loo nkqubo ibizwa isidoda lwesilinganiso thermal.
