Le conductivity thermal zezobhedu. A impahla ephawulekayo

indima sobhedu zibalulekile kwimbali yempucuko yabantu. Kwaba nabantu bakhe baqalisa ukuba yokunyibilikisa isinyithi, ndandifunda ukudala izixhobo, izinto zodongwe, izacholo, kunye nemali. Kwaye zonke enkosi iimpawu ezizodwa olu, kuboniswe ingxubevange kunye nezinye izinto. Into ethambileyo, into ixesha elide, i elinjubaqa, linyibilike kwamandla. It uneempawu ezininzi ezahlukeneyo, yaye omnye wabo ke conductivity wobushushu zezobhedu.

Xa sithetha ngalo laka, kuyimfuneko ukuba ukucacisa oko busengozini. Wabiza conductivity thermal kwento ukutshintshela ubushushu ukusuka isabelo ndinobushushu umkhuhlane. Ngoko ke, lo conductivity wobushushu ngobhedu yenye enyangweni phakathi nesinyithi. njani ukuvavanya lo propati njengoko elungileyo okanye embi?

Ukuba ucele abapheki nabapheki, bathi njengoko kulungileyo, apho neempahla zobhedu transfers kakuhle bubushushu emlilweni ukuya imveliso kulungiswa, kwaye ubushushu ngokulinganayo isasazwe phezu komhlaba wadibana edangatyeni.

Kakade ke, ezinye iintsimbi, yaye hayi kuphela zesinyithi, transfer ubushushu okanye, kungenjalo, ilifa conductivity ngokwaneleyo, kodwa nobhedu, eli khono ngomnye conductivity kuthiwa-thermal ngumlingani ilungileyo sobhedu yeyona iphezulu ngasentla isiliva kuphela.

umthamo ophawulekayo ibonelela ngamathuba angawo lokusebenzisa metal kwiinkalo ezahlukeneyo. Kuzo zonke iinkqubo zotshintshiselwano ubushushu sobhedu na umviwa lokuqala isicelo. Umzekelo, kwi Electro izixhobo okanye isithuthi kwiradiyetha, apho njengesipholisi fluid eshushu unika ubushushu obugqithisileyo.

Ngoku uzame ukuqonda ukuba yintoni eyabangela isiphumo transfer ubushushu. Kwenzeka ntoni kuchazwe kakhulu nje. Kukho unikezelo amandla efanayo phezu umthamo eziphathekayo. U nga tshinela isifaniso kunye igesi ekucaphukisayo. Kanye ngesitya elikhohlakeleyo igesi loo ithatha yonke indawo. Ngoko ke apha, ukuba wentsimbi itshiswe nawuphi na ummandla othile, amandla ngenxa isasazwa ngokulinganayo kulo mbandela.

Loo into kungachazwa ukuba conductivity wobushushu zezobhedu. Ngaphandle wangena physics quantum, kunokuthiwa ukuba ngenxa njengomthombo wamandla wangaphandle (ubushushu) le-athom ufumana amandla ezongezelelweyo kunye ize yona kwenye atom. I-eneji (ubushushu) ezisasazwa kuzo ivolyum into, ebangela ukufudumeza yayo yonke. Oku kwenzeka nayo nayiphi na into.

Umahluko kuphela kukuba ubhedu, nto leyo conductivity thermal eziphakamileyo kakhulu, transfers elungileyo ubushushu, kunye nezinye izinto benze okubi kakhulu into efanayo. Kodwa kwiimeko ezininzi kusenokuba impahla kuyimfuneko. On impahla kwezinto kakubi ukuqhuba yokugquma esekelwe ubushushu, ngenxa transfer ubushushu ihlwempu lungenzeki ilahleko yakhe. ukwambathisa Thermal kwizakhiwo yenza kube lula ukugcina iimeko zokuphila obutofotofo kwi kuneqabaka bumandundu.

Ukutshintshisana amandla okanye, njengoko kwimeko yethu, transfer ubushushu, kwaye inokuba zezixhobo ezahlukeneyo, ukuba sele nokugilana. Oku kwenzeka ntoni xa sibeka iketile phezu komlilo. Kuyinto amanzi shushu uze olulophu izitya. Ngenxa iimpawu eziphathekayo transfer ubushushu kwenzeka. transfer Ubushushu ixhomekeke phezu izinto ezininzi, kuquka iimpawu umbandela ngokwayo, ezifana esimsulwa. Ngoko ke, ukuba conductivity wobushushu zobhedu nto ilunge ngaphezu kokuba ezinye zesinyithi, uye aluminium zayo, lobhedu nobhedu babe conductivity ubushushu kakhulu ahlwempuzekileyo.

Ukuthetha ngayo ezi zakhiwo, kufanele kuqatshelwe ukuba conductivity thermal ixhomekeke lobushushu. Nkqu ubhedu kakhulu olunyulu ezinomthamo ka-99,8%, njengoko ubushushu kwandisa amathontsi conductivity thermal, kunye nezinye zesinyithi ezifana nobhedu manganese, kunye ukwandisa lobushushu ingumlingani ukunyuka.

Xa inkcazo engasentla, ingcaciso enikwe ngayo ingqiqo njengoko conductivity thermal, zibangelwa ophathekayo, umzekelo zekopolo nezinye izinto ingqalelo ezinye izicelo zezi mihlaba kubomi bemihla ngemihla.
