Isayensi Yokushisa: Izinhlobo Zokumelana Kagesi Ukuvikelwa Kwezinto Zokushisa

AInhliziyo yazo zonke izikhala zomsebenzi kagesi yinto yokushisa. Akunandaba ukuthi i-heater iyingcindezelo kangakanani, noma ngabe kukushisa okukhanyayo, kugcwala uwoyela, noma kuphoqelelwa fan, endaweni ethile ngaphakathi kuyinto yokushisa umsebenzi ekushiseni ugesi kube ukushisa.

SIzikhathi ezithile ungabona into evuthayo, ekhazimulayo ebomvu - ishisa ngokuzivikela nge-grille evikelayo. Kwezinye izikhathi kufihlwe ngaphakathi, kuvikelwe ngokukhangwa kwensimbi nepulasitiki, kepha ukupompa ukuphuma okufanayo. Lokho okwenziwe yinto yokushisa eyenziwe ngayo nokuthi kwenziwa kanjani ukuthinta ngqo kanjani ukuthi i-heater isebenza kahle kangakanani, nokuthi izoqhubeka nokusebenza isikhathi esingakanani ukusebenza.

Ukumelana nocingo

By Kude, impahla esetshenziswa kakhulu yezinto zokushisa iyizintambo zensimbi noma izimbambo, ngokuvamile ezibizwa ngokuthi yi-wire yokumelana. Lokhu kungahlanganiswa kuqinile noma kusetshenziswe njengemichilo efulethini, kuya ngokucushwa kwensiza. Uma isikhathi eside ucezu lwentambo, kuzokukhipha khona ukushisa okwengeziwe.

TI-Hork Alloys ehlukahlukene isetshenziselwa izinhlelo zokusebenza ezikhethekile,NichromeIhlala ithandwa kakhulu esetshenziselwa ama-heater esikhala neminye imisebenzi emincane.I-Nichrome 80/20 iyi-alloy ye-80% nickel ne-chromium engama-20%.Lezi zimfanelo zikwenza kube yinto enhle yokushisa:

  1. Ukumelana okuphezulu
  2. Kulula ukusebenza nokwakheka
  3. Ayisebenzi noma iwohloka emoyeni, ngakho-ke kuhlala isikhathi eside
  4. Ayikhuli kabanzi lapho ifudumala
  5. Iphuzu eliphakeme elincibilikayo elingaba ngu-2550 ° F (1400 ° C)

OAma-alloys atholakala ngokuvamile ezintweni ezifudumele afaka i-kanthal (i-fecalral) ne-cupnonickel (Cuni), yize lezi azivame ukusetshenziswa ekushiseni kwesikhala.

Ama-heramic ama-heramic

RNgokushesha, izinto zokushisa ubumba ze-ceramic bezikhula ngokuthandwa. Lokhu kusebenza ngaphansi kothisha bakagesi obufanayo bokumelana nogesi njengocingo lokumelana, ngaphandle kokuthi insimbi ithathelwa indawo amapuleti we-PTC ceramic.

PI-TC Ceramic (imvamisa i-barium titanate, i-batio3) yaqanjwa kanjalo ngoba ine-coefficient evumayo yokumelana, okusho ukuthi ukumelana nokumelana kuyanda ekushiseni. Le mpahla yokuzikhawulela isebenza njenge-thermostat yemvelo - izishibhile ezibonakalayo ze-ceramic ngokushesha, kodwa ithafa uma izinga lokushisa elichazwe lifinyelelwe. Lapho i-TEMP inyuka, ukumelana kuyanda, okuholela ekunciphiseni kokushisa kokushisa. Lokhu kunikeza ukufudumala okufanayo ngaphandle kokuhluka kwamandla.

TUbuhle be-Ceramic Heater bafaka:

  1. Ukufudumala okusheshayo
  2. Ukushisa okuphansi komhlaba, ubungozi bomlilo obuncishisiwe
  3. Impilo ende
  4. Umsebenzi wokuzilawula

In iningi lama-heater space, amaphaneli e-ceramic ahlelwe ngokucushwa kwezinyosi, futhi anamathiselwe kuma-aluminium ama-baffles aqondisa ukushisa ngaphandle kwe-heater emoyeni.

Amalambu okushisa agqamile noma athambile

TUhlabelela i-bulb ekhanyayo njengobude be-wire yokumelana, yize eyenziwe nge-tungsten yokuphuma okukhanyayo lapho kufudunyezwa (okungukuthi, i-incandescence). I-filament eshisayo ifakwe eglasini noma i-quartz, egcwele i-inert gas noma ikhishwe umoya ukuze ivikele i-oxidation.

II-Ea Space heater, i-fallament yesibani yokushisa imvamisaNichrome, futhi amandla wondliwa ngawo ngamandla amakhulu angaphezu kwamandla aphezulu, ukuze i-filament ikhishwe infrared esikhundleni sokukhanya okubonakalayo. Ngaphezu kwalokho, ukufutheka kwe-quartz kuvame ukugcwala okubomvu ukuze kuncishiswe inani lokukhanya okubonakalayo okukhishwe (kungaba buhlungu ngamehlo ethu, ngenye indlela). Into yokushisa imvamisa isekelwa yinkomba eqondisa ukushisa ngendlela eyodwa.

TUnezinzuzo zamalambu wokushisa akhanyayo yile:

  1. Akunasikhathi sokushisa, uzizwa ufudumele ngokushesha
  2. Sebenza buthule, ngoba awukho umoya oshisayo odinga fan
  3. Hlinzeka ngokushisa kwamabala ezindaweni ezivulekile nangaphandle, lapho umoya ovuthayo uzowuhlakaza khona

NO yindaba ukuthi hlobo luni lokushisa i-heater yakho olunalo, kunenzuzo eyodwa bonke abanayo: Ukuvikelwa kokumelana nogesi kucishe kube yi-100% esebenza kahle. Lokho kusho ukuthi wonke ugesi ongena ku-resistor uguqulwa abe ukushisa kwesikhala sakho. Lokho kusiza wonke umuntu angayazisa, ikakhulukazi uma kufika isikhathi sokukhokha izikweletu!
