AInhliziyo yawo wonke ama-heater kagesi iyisici sokushisa. Kungakhathaliseki ukuthi i-heater sikhulu kangakanani, kungakhathaliseki ukuthi ukushisa okukhazimulayo, ukugcwala uwoyela, noma ukuphoqelelwa yifeni, endaweni ethile ngaphakathi kunesici sokushisisa umsebenzi wawo owukuguqula ugesi ube ukushisa.

Sngesinye isikhathi ungabona isici sokushisa, sibengezela ngokubomvu-sishisayo ngokusebenzisa i-grille evikelayo. Kwesinye isikhathi ifihlwa ngaphakathi, ivikelwe ngamagobolondo ensimbi nepulasitiki, kodwa ikhipha ukushisa ngokufanayo. Isici sokushisisa senziwe ngani nokuthi siklanywe kanjani kunomthelela oqondile ekutheni i-heater isebenza kahle kangakanani, nokuthi izoqhubeka isebenza isikhathi esingakanani.

I-Resistance Wire

By kude, izinto ezisetshenziswa kakhulu ekushiseni izintambo zensimbi noma amaribhoni, ngokuvamile abizwa nge-resistance wire. Lawa angahlanganiswa aqine noma asetshenziswe njengemicu eyisicaba, kuye ngokumiswa komshini. Uma ucezu locingo lude, luzokhiqiza ukushisa okwengeziwe.

Tama-alloys ahlukahlukene asetshenziselwa izicelo ezikhethekile,I-Nichromeihlala idume kakhulu esetshenziselwa izifudumezi zasemkhathini nezinye izinto ezisetshenziswayo ezincane.I-Nichrome 80/20 iyingxubevange ye-nickel engu-80% kanye ne-chromium engu-20%.Lezi zimfanelo ziyenza ibe isici esihle sokushisisa:

1. Ukumelana okuphezulu
2. Kulula ukusebenza nokuma
3. Ayifaki oxidize noma yonakalise emoyeni, ngakho ihlala isikhathi eside
4. Ayinwebi kakhulu uma ishisa
5. Iphuzu elincibilikayo eliphezulu elingaba ngu-2550°F (1400°C)

Oama-alloys avame ukutholakala ezintweni zokushisisa ahlanganisa i-Kanthal (FeCrAl) kanye ne-Cupronickel (CuNi), nakuba lezi zingavamile ukusetshenziswa kuzifudumezi zasemkhathini.

Izifudumezi ze-Ceramic

Rmuva nje, izakhi zokushisa ze-ceramic bezilokhu zikhula ngokuthandwa. Lezi zisebenza ngaphansi kwezinhloko ezifanayo zokumelana nogesi njengentambo yokumelana, ngaphandle kokuthi insimbi ithathelwa indawo amapuleti e-PTC ceramic.

PI-TC ceramic (imvamisa i-barium titanate, i-BaTiO3) ibizwa kanjalo ngenxa yokuthi ine-coefficient eshisayo yokumelana, okusho ukuthi ukumelana kuyenyuka lapho kushiswa. Le ndawo yokuzikhawulela isebenza njenge-thermostat yemvelo - impahla ye-ceramic ishisa ngokushesha, kodwa i-plateau uma izinga lokushisa elichazwe ngaphambilini selifinyelelwe. Lapho izinga lokushisa likhuphuka, ukumelana kuyanda, okuholela ekwehleni kokukhishwa kokushisa. Lokhu kunikeza ukushisa okufanayo ngaphandle kokuhlukahluka kwamandla.

TIzinzuzo ze-heaters ze-ceramic zihlanganisa:

1. Ukufudumala ngokushesha
2. Izinga lokushisa eliphansi, ingozi yomlilo iyancipha
3. Impilo ende
4. Umsebenzi wokuzilawula

In izifudumezi eziningi zasemkhathini, amaphaneli e-ceramic ahlotshiswe ngendlela yekhekheba lezinyosi, futhi anamathiselwe kuma-baffle e-aluminium aqondisa ukushisa kuphume kuhitha emoyeni, ngaphandle kosizo lwefeni.

Amalambu Okushisa Akhazimulayo noma E-infrared

TI-filament ku-bulb isebenza njengobude bentambo yokumelana, nakuba yenziwe nge-tungsten ukuze kukhishwe ukukhanya okwandayo lapho kushiswa (okungukuthi, incandescence). Umcu oshisayo uvalwe engilazini noma ku-quartz, okungenzeka ukuthi ugcwaliswe igesi engasebenzi noma okhishwe emoyeni ukuze uwuvikele ekufakweni kwe-oxidation.

Inge-heater yesikhala, i-filament yesibani sokushisa ijwayelekileI-Nichrome, futhi amandla anikezwa ngawo ngamandla angaphansi kwamakhulu, ukuze umcu ocwebezelayo ukhiphe infrared esikhundleni sokukhanya okubonakalayo. Ngaphezu kwalokho, i-quartz sheathing ngokuvamile ifakwe umbala obomvu ukuze kuncishiswe inani lokukhanya okubonakalayo okukhishwayo (kungaba buhlungu emehlweni ethu, ngaphandle kwalokho). Isici sokushisa ngokuvamile sisekelwa isibonisi esiqondisa ukushisa endaweni eyodwa.

TIzinzuzo zamalambu okushisa akhazimulayo yilezi:

1. Asikho isikhathi sokushisa, uzizwa ufudumele ngokushesha
2. Sebenza buthule, ngoba awukho umoya oshisayo odinga isiphephetha-moya
3. Nikeza ukushisisa izindawo ezindaweni ezivulekile nangaphandle, lapho umoya oshisayo uzohlakazeka khona

No kungakhathaliseki ukuthi hlobo luni lwesici sokushisisa isifudumezi sakho sinaso, kunenzuzo eyodwa zonke abanazo: izifudumezi ezingazwani nogesi zisebenza kahle ngo-100%. Lokho kusho ukuthi wonke ugesi ongena ku-resistor uguqulwa ube ukushisa kwendawo yakho. Lokho kuyinzuzo wonke umuntu angayazisa, ikakhulukazi uma kufika isikhathi sokukhokha izikweletu!
