Isebenza kanjani i-heating element?

Wake wazibuza ukuthi i-heater yakho kagesi, i-toaster, noma eyomile yezinwele ikhiqiza ukushisa? Impendulo ilele kudivayisi ebizwa ngokuthi yinto yokushisa, eguqula amandla kagesi abe ukushisa inqubo yokumelana. Kulesi sipongo sebhulogi, sizochaza ukuthi iyiphi into yokushisa, isebenza kanjani, futhi yiziphi izinhlobo ezahlukene zezinto zokushisa ezitholakalayo. Sizokwethula futhi ku-Beeco Electronics, omunye wabakhiqizi abahamba phambili bokushisa eNdiya, abakwazi ukukunikeza ngezinto ezisezingeni eliphakeme futhi ezingabizi kakhulu zokushisa kwezicelo ezahlukahlukene.

Yini into yokushisa?

Into yokushisa yithuluzi elikhiqiza ukushisa lapho okukhona ngogesi kudlula kukho. Imvamisa yenziwa ngekhoyili, iribhoni, noma umucu wocingo onokumelana okuphezulu, okusho ukuthi kuphikisana nokugeleza kukagesi futhi kukhiqize ukushisa ngenxa yalokho. Le nto yaziwa ngokuthi i-joule heating noma ukushisa okumelana nayo futhi kuyisimiso esifanayo esenza isibani esikhanyayo sikhanye. Inani lokushisa elikhiqizwa yinto yokushisa lincike kumandla kagesi, okwamanje, kanye nokumelana kwento, kanye nokuqukethwe kanye nokwakheka kwento.

Isebenza kanjani i-heating element?

Into yokushisa isebenza ngokuguqula amandla kagesi abe ukushisa ngenqubo yokumelana. Lapho ugesi ugeleza edlula entweni, uhlangabezana nokumelana, okubangela amanye amandla kagesi aguqulwe abe ukushisa. Ukushisa bese kukhalela kusuka entweni kuzo zonke izinkomba, kufudumeza umoya ozungezile noma izinto. Izinga lokushisa lento lincike ekulinganiseni phakathi kokushisa okukhiqizwayo kanye nokushisa okulahlekelwe yimvelo. Uma ukushisa okukhiqizwa kukhulu kunokushisa okulahlekile, into izoshisa, futhi okuphambene nalokho.

Yiziphi izinhlobo ezahlukene zezinto zokushisa?

Kunezinhlobo ezahlukene zezinto zokushisa, ngokuya ngezinto ezibonakalayo, ukwakheka kanye nokusebenza kwento. Ezinye izinhlobo ezijwayelekile zezinto zokushisa yilezi:

Izinto zokuvimbela insimbi yensimbi: Lezi yizinto zokushisa ezenziwe ngezintambo zensimbi noma izimbambo, njenge-nichrome, i-kanthal, noma i-cupnonickel. Zisetshenziselwa amadivaysi afanayo okushisa anjenge-heater, ama-adayeji, izinhlamba zezinwele, izinsimbi, namahhavini. Banokumelana okuphezulu futhi bakha ungqimba oluvikelayo lwe-oxide lapho befudumeza, bevimbela ezinye i-oxidation kanye nokugqwala.

Izinto zokushisa i-foil ezi-etched Zisetshenziselwa izinhlelo zokushisa ngokunemba njengokuxilongwa kwezokwelapha kanye ne-aerospace. Banokumelana okuphansi futhi banganikeza ukusatshalaliswa kokushisa komfaniswano nokungaguquki.

Izinto zokushisa zokushisa ze-ceramic ne-semiconductor: Lezi yizinto zokushisa ezenziwe ngezinto zokwakha ze-ceramic noma ze-semiconductor, ezinjenge-molybdenum zivuselelwa, i-silicon carbide, noma i-silicon nitride. Zisetshenziselwa izinhlelo zokushisa zokushisa okuphezulu ezifana nomkhakha wengilazi, ama-plug ama-plugs we-ceramic enjini, kanye ne-diesel injini evuthayo. Banokumelana ngokulinganisela futhi bangamelana nokugqwala, i-oxidation, kanye nokushaqeka okushisayo.

Izinto zokushisa kwe-PTC Ceramic Zisetshenziselwa izinhlelo zokusebenza zokuzilawula ezisebenzisa izivimbi zezihlalo zemoto, abaqondisayo bezinwele, kanye nabenzi bekhofi. Banokumelana kwe-nonlinear futhi banganikeza ukusebenza kahle kokuphepha kanye namandla.
