APakatikati pa chotenthetsera chilichonse chamagetsi ndi chinthu chotenthetsera. Ziribe kanthu kuti chotenthetseracho ndi chachikulu chotani, mosasamala kanthu kuti ndi kutentha kwakukulu, kudzazidwa ndi mafuta, kapena kukakamizidwa, kwinakwake mkati mwake muli chinthu chotenthetsera chomwe ntchito yake ndikusintha magetsi kukhala kutentha.

Snthawi zina mumatha kuwona chotenthetsera, chonyezimira chofiyira kudzera pa grille yoteteza. Nthawi zina zimabisika mkati, zotetezedwa ndi zitsulo ndi pulasitiki, koma zimatulutsa kutentha mofanana. Zomwe chotenthetseracho chimapangidwira komanso momwe chimapangidwira zimakhudza momwe chotenthetsera chimagwirira ntchito, komanso kuti chipitirire kugwira ntchito mpaka liti.

Resistance Waya

By kutali, zinthu zomwe zimagwiritsidwa ntchito kwambiri potenthetsera zinthu ndi mawaya achitsulo kapena maliboni, omwe nthawi zambiri amatchedwa waya wotsutsa. Izi zitha kukulungidwa zolimba kapena kugwiritsidwa ntchito ngati mizere yosalala, kutengera masinthidwe a chipangizocho. Wayayo akatalikirapo, m'pamenenso amatentha kwambiri.

Though ma aloyi osiyanasiyana amagwiritsidwa ntchito mwapadera,Nichromeimakhalabe yomwe imagwiritsidwa ntchito kwambiri popangira ma heater ndi zida zina zazing'ono.Nichrome 80/20 ndi aloyi wa 80% faifi tambala ndi 20% chromium.Makhalidwe awa amapangitsa kukhala chinthu chabwino chotenthetsera:

1. Kukana kwakukulu
2. Zosavuta kugwira ntchito komanso mawonekedwe
3. Simawonjezera oxidize kapena kuwonongeka mumpweya, motero imatenga nthawi yayitali
4. Sichimakula kwambiri pamene chikuwotcha
5. Malo osungunuka kwambiri pafupifupi 2550°F (1400°C)

OMa aloyi omwe amapezeka muzinthu zotenthetsera ndi Kanthal (FeCrAl) ndi Cupronickel (CuNi), ngakhale izi sizimagwiritsidwa ntchito nthawi zambiri muzotenthetsera.

Ma heaters a ceramic

RPosachedwa, zinthu zotenthetsera za ceramic zayamba kutchuka. Izi zimagwira ntchito pansi pazikulu zomwezo za resistivity yamagetsi monga waya wotsutsa, kupatula chitsulocho chimasinthidwa ndi mbale za ceramic za PTC.

PTC ceramic (kawirikawiri barium titanate, BaTiO3) imatchedwa chifukwa ili ndi mphamvu yokwanira yolimbana ndi kutentha, zomwe zikutanthauza kuti kukana kumawonjezeka pakatentha. Katundu wodziletsa yekhayu amakhala ngati thermostat yachilengedwe - zida za ceramic zimatenthetsa mwachangu, koma mapiri akangofika kutentha komwe kumatanthauzidwa kale. Pamene kutentha kumawonjezeka, kukana kumawonjezeka, zomwe zimabweretsa kuchepa kwa kutentha. Izi zimapereka kutentha kofanana popanda kusintha kwa mphamvu.

TUbwino wa ma heaters a ceramic ndi awa:

1. Kutenthetsa mwachangu
2. Kutentha kwapansi pamtunda, kuchepetsa ngozi ya moto
3. Moyo wautali
4. Ntchito yodzilamulira

In zotenthetsera zambiri zam'mlengalenga, mapanelo a ceramic amakongoletsedwa mwachisa cha uchi, ndipo amamangiriridwa pazitsulo za aluminiyamu zomwe zimawongolera kutentha kuchokera mu chotenthetsera kupita mumlengalenga, popanda thandizo la fani.

Nyali Zoyaka Zowala kapena Infrared

Tamapangidwa ndi tungsten kuti awonjezere kuwala akatenthedwa (ndiko kuti, incandescence). Filament yotentha imakutidwa mu galasi kapena quartz, yomwe imadzazidwa ndi mpweya wa inert kapena kutulutsa mpweya kuti utetezedwe ku okosijeni.

Indi chotenthetsera danga, nyali kutentha filament zambiriNichrome, ndipo mphamvu imadyetsedwa kupyolera mu mphamvu yochepa kwambiri, kotero kuti ulusiwo umatulutsa infrared m'malo mwa kuwala kowonekera. Kuonjezera apo, quartz sheathing nthawi zambiri imakhala yofiira pofuna kuchepetsa kuwala kowonekera komwe kumatulutsa (zingakhale zopweteka kwa maso athu, mwinamwake). Chinthu chotenthetsera nthawi zambiri chimathandizidwa ndi chowonetsera chomwe chimawongolera kutentha kumalo amodzi.

TUbwino wa nyali zoyaka moto ndi izi:

1. Palibe kutentha nthawi, mumamva kutentha nthawi yomweyo
2. Gwirani ntchito mwakachetechete, popeza kulibe mpweya wotentha womwe umafuna fani
3. Perekani kutentha pamalo otseguka ndi panja, momwe mpweya wotentha umatha

No zilibe kanthu kuti chotenthetsera chanu chili ndi mtundu wanji, pali mwayi umodzi womwe onse ali nawo: zowotchera zamagetsi zimakhala zogwira mtima 100%. Izi zikutanthauza kuti magetsi onse omwe amalowa mu resistor amasinthidwa kukhala kutentha kwa malo anu. Ili ndi phindu lomwe aliyense angayamikire, makamaka ikafika nthawi yolipira!
