AIntliziyo yesifudumezi ngasinye sombane sisixhobo sokufudumeza. Kungakhathaliseki ukuba sikhulu kangakanani isifudumezi, akukhathaliseki nokuba bubushushu obukhazimlayo, buzaliswe ngeoli, okanye bunyanzelwa yifeni, ndaweni ithile ngaphakathi kukho into yokufudumeza umsebenzi wayo ikukuguqula umbane ube bubushushu.

Sngamanye amaxesha unokubona into yokufudumeza, ibengezelayo ebomvu-eshushu ngokusebenzisa igrille ekhuselayo. Ngamanye amaxesha ifihlwe ngaphakathi, ikhuselwe ziintsimbi zentsimbi kunye neplastiki, kodwa ikhupha ubushushu ngokufanayo. Isixhobo sokufudumeza senziwe ngantoni kwaye siyilwe njani sichaphazela ngokuthe ngqo indlela isifudumezi esisebenza ngayo, kwaye siya kuqhubeka ixesha elingakanani sisebenza.

I-Resistance Wire

By kude, izinto eziqhelekileyo ezisetyenziselwa ukufudumeza izinto ziingcingo zetsimbi okanye iiribhoni, ezibizwa ngokuba yi-resistance wire. Ezi zinokubhijelwa ngqingqwa okanye zisetyenziswe njengeentambo ezisicaba, ngokuxhomekeke kubume besixhobo sombane. Okukhona iqhekeza locingo lide, kokukhona liya kuvelisa ubushushu.

Tii-alloys ezahlukeneyo zisetyenziselwa usetyenziso olukhethekileyo,Nichromeihlala iyeyona idumileyo esetyenziselwa izifudumezi kunye nezinye izixhobo ezincinci.I-Nichrome 80/20 yi-alloy ye-80% ye-nickel kunye ne-20% ye-chromium.Ezi mpawu ziyenza ibe yinto efanelekileyo yokufudumeza:

1. Ukuxhathisa okuphezulu
2. Kulula ukusebenza kunye nokumila
3. Ayina oxidize okanye yonakele emoyeni, ngoko ihlala ixesha elide
4. Ayinandisi kakhulu xa ishushu
5. Indawo yokunyibilika ephezulu malunga nama-2550°F (1400°C)

Oiialloyi eziqhele ukufunyanwa kwizinto zokufudumeza ziquka iKanthal (FeCrAl) kunye neCupronickel (CuNi), nangona ezi zingasetyenziswa kakhulu kwizifudumezi zasesithubeni.

Izifudumezi zeCeramic

RKutshanje, izinto zokufudumeza ze-ceramic ziye zakhula ekuthandeni. Ezi zisebenza phantsi kweenqununu ezifanayo zokumelana nombane njengocingo oluchasayo, ngaphandle kokuba isinyithi sitshintshwa ngamacwecwe e-PTC ceramic.

PI-TC ceramic (idla ngokuba yi-barium titanate, i-BaTiO3) ithiywe ngolo hlobo ngenxa yokuba ine-coefficient ye-thermal esebenzayo yokumelana, okuthetha ukuxhathisa ukunyuka xa kufudumeza. Le propati yokuzimela ngokwayo isebenza njenge-thermostat yendalo - izinto ze-ceramic zitshisa ngokukhawuleza, kodwa i-plateaus xa iqondo lokushisa elichazwe ngaphambili lifikeleleke. Xa iqondo lokushisa linyuka, ukuxhathisa kuyanda, okukhokelela ekunciphiseni ukukhutshwa kobushushu. Oku kubonelela ngokufudumeza okufanayo ngaphandle kokuhluka kwamandla.

Tiingenelo zakhe izifudumezi ceramic ziquka:

1. Ukufudumala ngokukhawuleza
2. Ukushisa okuphantsi komhlaba, ukunciphisa umngcipheko womlilo
3. Ubomi obude
4. Umsebenzi wokuzilawula

In ezininzi izifudumezi isithuba, iiphaneli ceramic wambathiswe kuqwalaselo lobusi, kwaye incanyathiselwe baffles aluminiyam esalathisa ubushushu ngaphandle heater emoyeni, kunye yethu ngaphandle koncedo ifeni.

I-Radiant okanye i-Infrared Heat Lamps

TI-filament kwibhalbhu yokukhanya isebenza njengobude bocingo lokumelana, nangona yenziwe nge-tungsten yokwandisa ukuphuma kokukhanya xa ishushu (oko kukuthi, incandescence). I-filament eshushu ifakwe kwiglasi okanye i-quartz, enokuthi izaliswe yigesi ye-inert okanye ikhutshwe emoyeni ukuze ikhuseleke kwi-oxidation.

Iisithuba isifudumezi, umcu wesibane sobushushu ngokuqhelekileyoNichrome, kwaye amandla ayondliwa ngayo ngaphantsi kwamandla aphezulu, ukuze i-filament iphume nge-infrared endaweni yokukhanya okubonakalayo. Ukongeza, i-quartz sheathing ihlala ifakwe ebomvu ukuze kuncitshiswe inani lokukhanya okubonakalayo okukhutshwayo (kuya kuba buhlungu emehlweni ethu, kungenjalo). Into yokufudumala idla ngokuxhaswa ngumbonakalisi olawula ukushisa kwicala elinye.

TUncedo kwizibane ezikhanyayo zezi:

1. Akukho xesha lokufudumala, uziva ushushu ngokukhawuleza
2. Sebenza ngokuthula, kuba akukho moya ushushu ufuna ifeni
3. Ukubonelela ngokufudumeza indawo kwiindawo ezivulekileyo nangaphandle, apho umoya oshushu uya kutshabalalisa

No akukhathaliseki nokuba loluphi uhlobo lwesixhobo sokufudumeza esinaso, kukho inzuzo enye abanayo bonke: izifudumezi ezinganyangekiyo zombane ziphantse zasebenza kakuhle nge-100%. Oko kuthetha ukuba wonke umbane ongena kwi-resistor uguqulwa ube bubushushu kwindawo yakho. Leyo yinzuzo wonke umntu anokuyixabisa, ngakumbi xa kufika ixesha lokuhlawula amatyala!
