PTCmakina otenthetsera mpweyandi njira yodziwika bwino yotenthetsera m'magalimoto atsopano amphamvu, makamaka m'magalimoto amagetsi enieni. Popeza magalimoto amagetsi alibe kutentha kochokera ku injini zoyatsira mkati, amafunika kudziyimira pawokhanjira zotenthetseraPTC ndi chidule cha "Positive Temperature Coefficient", chomwe chimatanthauza positive temperature coefficient. Kukana kwa chinthuchi kumawonjezeka ndi kukwera kwa kutentha.
Mfundo yogwirira ntchito yaChotenthetsera mpweya cha PTCNdi kugwiritsa ntchito khalidwe la zinthu za PTC popanga kutentha podutsa mphamvu kudzera mu chinthu cha PTC. Chinthu cha PTC chikatenthedwa, mphamvu yake yolimbana nayo imawonjezeka ndi kutentha komwe kumawonjezeka, motero kuchepetsa kuwonjezeka kwa mphamvu, kukhala ndi mphamvu yodzilamulira yokha komanso kusunga kutentha kosalekeza. Chotenthetsera ichi chili ndi makhalidwe osunga mphamvu, kutentha kosalekeza, chitetezo komanso moyo wautali wa ntchito.
Mu magalimoto atsopano amphamvu, zotenthetsera mpweya za PTC nthawi zambiri zimakhala ndi zinthu za PTC, zotenthetsera kutentha ndi zophimba.Chinthu cha PTCndiye gawo lalikulu lomwe limayang'anira kutentha; chotenthetsera chimagwiritsidwa ntchito kuchotsera kutentha; nyumbayo imateteza chotenthetsera kuti chipewe zoopsa monga kugwedezeka kwa magetsi. Chotenthetsera mpweya cha PTC chimatha kutentha mpweya mwachindunji kapena mwanjira ina potenthetsera chotenthetsera. Njira yotenthetsera mpweya mwachindunji ili ndi kapangidwe kosavuta, koma pakhoza kukhala zoopsa zachitetezo; njira yotenthetsera mpweya mwachindunji imagwiritsa ntchito pampu yotenthetsera kuti ipompe chotenthetsera kupita ku radiator mgalimoto, ndipo imagwiritsa ntchito kutentha kuchokera ku chotenthetsera kuti itenthe mpweya. Njirayi imapewa kulowetsa mafunde akuluakulu ndi ma voltage ambiri mgalimoto ndipo ili ndi chitetezo chapamwamba, koma dongosololi ndi lovuta kwambiri ndipo mtengo wake ndi wokwera.
Ubwino wa ma heater a PTC ndi monga kukana kutentha pang'ono, kutentha mwachangu, mphamvu yogwira ntchito kwambiri, mphamvu yodziletsa yokha, moyo wautali, komanso kukhwima kwa zinthu. Komabe, zovuta zake ndizodziwikiratu, makamaka kugwiritsa ntchito mphamvu zambiri, zomwe zingachepetse kuchuluka kwa magalimoto amagetsi. Kuphatikiza apo, kutentha kwa pamwamba pa ma heater a PTC ndi kwakukulu, komwe kumatha kutentha mapulasitiki ozungulira ndikutulutsa fungo, kotero chisamaliro chapadera chiyenera kuperekedwa popanga malo oyika heater.
Mu ntchito zenizeni, makina owongolera a chotenthetsera mpweya cha PTC adzasintha mphamvu ya chotenthetsera malinga ndi zomwe zili mu sensa ya kutentha m'galimoto kuti zikwaniritse zosowa za okwera pomwe akuchepetsa kugwiritsa ntchito mphamvu. Mtundu uwu wa chotenthetsera umagwiritsidwa ntchito kwambiri m'magalimoto atsopano amphamvu, makamaka m'malo omwe kutentha mwachangu komanso chitetezo chapamwamba zimafunikira.
