Isebenza Kanjani Isici Sokushisa?
Wake wazibuza ukuthi i-heater kagesi, i-toaster, noma isomisi sezinwele ikukhiqiza kanjani ukushisa? Impendulo isesisetshenziswa esibizwa ngokuthi i-heater, eguqula amandla kagesi abe ukushisa ngenqubo yokumelana. Kulokhu okuthunyelwe kwebhulogi, sizochaza ukuthi iyini into yokushisa, ukuthi isebenza kanjani, futhi yiziphi izinhlobo ezahlukene zezinto zokushisa ezitholakalayo. Sizophinde futhi sikwethule i-Beeco Electronics, omunye wabakhiqizi abahamba phambili bezinto zokushisisa e-India, ongakunikeza izinto zokushisisa zekhwalithi ephezulu nezithengekayo zezinhlelo zokusebenza ezahlukahlukene.
Iyini into yokushisisa?
Isici sokushisisa iyisisetshenziswa ekhiqiza ukushisa lapho umsinga kagesi udlula kuwo. Ngokuvamile kwenziwa ikhoyili, iribhoni, noma umucu wocingo onokumelana okuphezulu, okusho ukuthi uphikisana nokugeleza kukagesi futhi ukhiqiza ukushisa ngenxa yalokho. Lesi simo saziwa ngokuthi ukushisisa kwe-Joule noma ukushisisa okuphikisayo futhi kuyisimiso esifanayo esenza isibani sokukhanya sikhanye. Inani lokushisa elikhiqizwa isici sokushisa lincike ku-voltage, yamanje, nokumelana kwesici, kanye nempahla nokuma kwesici.
Isebenza kanjani into yokushisisa?
Isici sokushisisa sisebenza ngokuguqula amandla kagesi abe ukushisa ngenqubo yokumelana. Uma i-electric current igeleza ku-elementi, ihlangabezana nokumelana, okubangela ukuthi amandla athile kagesi aguqulwe abe ukushisa. Ukushisa bese kukhipha i-elementi kuzo zonke izinhlangothi, kushisisa umoya ozungezile noma izinto. Izinga lokushisa le-elementi lincike ebhalansini phakathi kokushisa okukhiqizwa kanye nokushisa okulahlekele endaweni ezungezile. Uma ukushisa okukhiqizwa kukukhulu kunokushisa okulahlekile, i-elementi izoshisa kakhulu, futhi ngokuphambene nalokho.
Yiziphi izinhlobo ezahlukene zezinto zokufudumeza?
Kunezinhlobo ezahlukene zezinto zokushisa, kuye ngokuthi impahla, ukuma, kanye nomsebenzi we-elementi. Ezinye zezinhlobo ezijwayelekile zezinto zokushisisa yilezi:
Izakhi zokushisa ezimelana nensimbi: Lezi izinto zokushisisa ezenziwe ngezintambo zensimbi noma amaribhoni, njenge-nichrome, kanthal, noma i-cupronickel. Asetshenziswa kumishini yokushisisa evamile njengamahitha, amathosta, okomisa izinwele, iziko, namahhavini. Zinokumelana okuphezulu futhi zakha ungqimba oluvikelayo lwe-oxide lapho kushisa, ukuvimbela i-oxidation eyengeziwe nokugqwala.
Izakhi zokushisa ze-foil ezigxiliwe: Lezi yizinto zokufudumeza ezenziwe ngamafoyili ensimbi, njengethusi noma i-aluminium, eziqoshwe kuphethini ethile. Asetshenziswa ezinhlelweni zokushisisa ezinembayo njengokuxilongwa kwezokwelapha kanye ne-aerospace. Banokumelana okuphansi futhi banganikeza ukusatshalaliswa kokushisa okufanayo nokungaguquki.
Izinto zokushisa ze-Ceramic ne-semiconductor: Lezi izinto zokufudumeza ezenziwe ngezinto zobumba zobumba noma ze-semiconductor, njenge-molybdenum disilicide, i-silicon carbide, noma i-silicon nitride. Asetshenziswa ezinhlelweni zokushisa ezishisa kakhulu njengezimboni zengilazi, i-ceramic sintering, namapulagi okukhanya kwenjini yedizili. Zinokumelana okumaphakathi futhi zingamelana nokugqwala, i-oxidation, nokushaqeka kwe-thermal.
Izakhi zokushisa ze-ceramic ze-PTC: Lezi yizakhi zokushisa ezenziwe ngezinto zobumba ezine-coefficient yokushisa enhle yokumelana, okusho ukuthi ukumelana kwazo kukhuphuka ngezinga lokushisa. Asetshenziswa ezinhlelweni zokufudumeza ezizilawulayo njengezifudumezi zezihlalo zemoto, okokuqondisa izinwele, nabenzi bekhofi. Zinokumelana okungeyona i-linear futhi zinganikeza ukuphepha nokusebenza kahle kwamandla.
