AInhliziyo yazo zonke izifudumezi zesikhala zikagesi iyisici sokushisa. Kungakhathaliseki ukuthi isifudumezi sikhulu kangakanani, kungakhathaliseki ukuthi sishisa kakhulu, sigcwele uwoyela, noma siphoqelelwa ifeni, endaweni ethile ngaphakathi kukhona isici sokushisa esinomsebenzi wokuguqula ugesi ube ukushisa.

SNgezinye izikhathi ungabona into yokushisa, ikhanya ngokushisa okubomvu nge-grille evikelayo. Ngezinye izikhathi ifihliwe ngaphakathi, ivikelwe yizingxenyana zensimbi nepulasitiki, kodwa ikhipha ukushisa noma kunjalo. Lokho into yokushisa eyenziwe ngakho nokuthi yakhiwe kanjani kuthinta ngqo indlela esebenza kahle ngayo i-heater, nokuthi izoqhubeka isebenza isikhathi esingakanani.

Ucingo Lokumelana

BNokho, izinto ezisetshenziswa kakhulu ekufudumaleni yizintambo zensimbi noma amaribhoni, ngokuvamile abizwa ngokuthi ucingo lokumelana. Lezi zingahlanganiswa ziqine noma zisetshenziswe njengemicu eyisicaba, kuye ngokuthi uhlelo lokusebenza luhlelwe kanjani. Uma ucingo lude, luzokhiqiza ukushisa okwengeziwe.

Tnoma ngabe izinhlobo ezahlukene ze-alloys zisetshenziselwa izinhlelo zokusebenza ezikhethekile,I-Nichromeisalokhu ithandwa kakhulu esetshenziswa kuma-heaters asemkhathini kanye nezinye izinto ezincane zikagesi.I-Nichrome 80/20 iyi-alloy engu-80% nickel kanye no-20% chromium.Lezi zimfanelo zenza kube yinto enhle yokushisa:

1. Ukumelana okuphezulu kakhulu
2. Kulula ukusebenza nokuma
3. Ayincibilikisi noma yonakale emoyeni, ngakho ihlala isikhathi eside
4. Ayikhuli kakhulu uma ishisa
5. Indawo yokuncibilika ephezulu cishe engu-2550°F (1400°C)

OAma-alloy atholakala kakhulu ezintweni zokushisa afaka i-Kanthal (FeCrAl) kanye ne-Cupronickel (CuNi), yize lawa engasetshenziswa kakhulu kuma-heater asemkhathini.

Izifudumezi ze-ceramic

RMuva nje, izinto zokushisa ze-ceramic bezilokhu zithandwa kakhulu. Lezi zisebenza ngaphansi kwemigomo efanayo yokumelana nogesi njengentambo yokumelana, ngaphandle kokuthi insimbi ithathelwa indawo amapuleti e-ceramic e-PTC.

PI-TC ceramic (ngokuvamile i-barium titanate, i-BaTiO3) ibizwa kanjalo ngoba ine-coefficient yokumelana nokushisa okuhle, okusho ukuthi ukumelana kuyanda lapho kushisa. Le mpahla ezikhawulelayo isebenza njenge-thermostat yemvelo - izinto ze-ceramic zishisa ngokushesha, kodwa ziyaphela uma izinga lokushisa elichazwe kusengaphambili selifinyelelwe. Lapho izinga lokushisa likhuphuka, ukumelana kuyanda, okuholela ekunciphiseni kokukhipha ukushisa. Lokhu kunikeza ukushisa okufanayo ngaphandle kokushintsha kwamandla.

TIzinzuzo zama-heater e-ceramic zifaka:

1. Ukufudumeza okusheshayo
2. Izinga lokushisa eliphansi, ingozi yomlilo encishisiwe
3. Impilo ende
4. Umsebenzi wokuzilawula

IEziningi zezifudumezi zesikhala, amaphaneli e-ceramic ahlelwe ngendlela yokwakheka kwe-honeycomb, futhi anamathiselwe kuma-baffle e-aluminium aqondisa ukushisa ngaphandle kwesifudumezi emoyeni, ngaphandle kosizo lwefeni.

Izibani Zokushisa Ezikhazimulayo Noma Ezine-Infrared

TIntambo ebhalbhu yokukhanya isebenza njengocingo olude lokumelana, yize yenziwe nge-tungsten ukuze kukhishwe ukukhanya okwengeziwe uma kushiswa (okungukuthi, i-incandescence). Intambo eshisayo imbozwe ngengilazi noma nge-quartz, egcwala igesi engasebenzi noma ekhishwa emoyeni ukuze ivikelwe ekungcolisweni.

Inge-heater yesikhala, intambo yesibani sokushisa ivame ukubaI-Nichrome, futhi amandla anikezwa ngayo ngamandla angaphansi kwamandla aphezulu, ukuze i-filament ikhiphe i-infrared esikhundleni sokukhanya okubonakalayo. Ngaphezu kwalokho, i-quartz sheathing ivame ukushintshwa ibe bomvu ukuze kuncishiswe inani lokukhanya okubonakalayo okukhishwayo (kungaba buhlungu emehlweni ethu, uma kungenjalo). Isici sokushisa sivame ukusekelwa yi-reflector eqondisa ukushisa ohlangothini olulodwa.

TIzinzuzo zezibani zokushisa ezikhazimulayo yilezi:

1. Asikho isikhathi sokushisa, uzizwa ufudumele ngokushesha
2. Sebenza buthule, njengoba kungekho moya oshisayo odinga ifeni
3. Nikeza ukushisa ezindaweni ezivulekile nangaphandle, lapho umoya oshisayo uzophela khona

NKungakhathaliseki ukuthi uhlobo luni lwesici sokushisa i-heater yakho enalo, kukhona inzuzo eyodwa zonke ezinayo: ama-heater amelana nogesi asebenza kahle cishe ngo-100%. Lokho kusho ukuthi wonke ugesi ongena ku-resistor uguqulwa ube ukushisa kwendawo yakho. Leyo inzuzo wonke umuntu angayazisa, ikakhulukazi uma sekuyisikhathi sokukhokha izikweletu!
