The thermal conductivity nke ikuku - ihe ọ bụ?

Kpa ye dị otú ahụ a echiche, ihe kwes conductivity nke ikuku, anyị na-amalite na-eche - gịnị ka ọ bụ ihe niile banyere? Nke a ibe mgbanwe nke ahụ n'etiti ozu, nke ahụ bụ isi, nke nwere a kpụ ọkụ n'ọnụ ahụ, ahụ na-agafe ahụ, nke ndị na-erughị kpụ ọkụ n'ọnụ.

Ọ bụrụ na anyị na-ekwu banyere okpomọkụ conduction na ikuku, ọ dị mkpa iburu n'obi eziokwu na nyefe nke molekụla ahụ na ohere, ya bụ, na e nwere molekụla ngagharị ahụ. The mgbanwe nwere ike iri ebe ma na homogeneous ozu, na dị iche iche na mejupụtara. Ndị dị otú ahụ okpomọkụ nyefe nwere ike emezu atọ kwuru, sị: gas, mmiri mmiri crystal (siri ike ikwu).

Kwes conductivity nke ikuku dị ime okpomọkụ equalization n'etiti ozu via anaghị achọ ma na-anata ndị kpụ ọkụ n'ọnụ ahụ. Iji mee nke a, ya kpọmkwem ngụkọta oge. Mkpebi Siri Ike nke kwes conductivity gbakọọ Fourier iwu site a pụrụ iche usoro. Ọ na-eji na-ewu ụlọ, akụkụ, ma ọ bụ ọ bụla ogige nke ga-itieutom, ma ọ bụ nke ike-eji dị ka ebe a na-anọ.

The thermal conductivity nke ikuku na-enyere na-ewu ụlọ na-ahọrọ nri otu ma ọ bụ ọzọ na ihe onwunwe, na-adabere nzube nke nrigbu nke ụlọ. Maka ogige ka na-emegharị na-na ọnọdụ, bulie ihe na ga-ejigide okpomọkụ na adịghị uche oyi ikuku eruba.

The kasị mma na-eduzi na-ekpo ọkụ ume dị iche iche iche iche nke, haruru. The kasị njọ na-eduzi - niile nkịtị ọla, dị ka ha kpo oku na-ebute ngagharị nke ahụ mkpa okpomọkụ, nke na nkịtị ọnọdụ enweghị ike na-enweta. Exchange nke ahụ n'etiti ozu pụrụ hụrụ mgbe anyị na-esi nri na stovu ma ọ a ọkụ.

Emepe a gas afụnwu ọkụ, anyị edita ya, si otú exotherm amalite eduzi ndị efere, mgbe nke ahụ nke ihe onwunwe nke na-ewu nke cookware, na-amalite na-okpomọkụ ya n'ime cookware umi, ma ọ bụ kpụ ọkụ n'ọnụ. Ndị dị otú ahụ ume usoro nyefe na-akọwa ihe kwes conductivity nke ikuku.

Kwes conductivity bụ ukwuu dabere na Ọdịdị nke bekee. Gịnị bụ porosity, ndị na-erughị conductivity. E nwere ndị dị otú ahụ a na okwu dị ka a mgbanwe thermal conductivity. Ọ bụ nke bekee nwere ike na-esi n'otu ala ọzọ, n'ihi na ihe atụ, ice na mmiri.

Ugbu a, n'ihe nke kwes conductivity nke a umi na-emepụta na-eji pụrụ iche ngwá na-ekwe ka isledovat thermal conductivity na kpụ ọkụ n'ọnụ elu nke ihe onwunwe na-tùa site 30 ka 750 degrees.

Ndị dị otú ahụ na ngwaọrụ na-ekewet ukwuu n'ime nke kpo oku mmewere, ngwa-nzaghachi okpomọkụ mita, nke na-emi odude ke thermocouple, na ndị na-ewu ya na-emi odude ke a metal casing nke jupụtara na-egbochi ihe onwunwe. The kpo oku mmewere, okpomọkụ mita na a friji guzobere a disk udi.

Ịmara ihe kwes conductivity nke ikuku, ị nwere ike itinye gị na ụlọ ma ọ bụ ulo ka ha na-ekpo ọkụ, ma na-enwe ike nye ndụmọdụ ndị ikwu ha nri na ha nwere ihe onwunwe, dị ka upholstery mgbidi a onwe ụlọ, nke mere na ọ bụ ala, mma na jụụ.
