Ngexesha leenyanga ezibandayo zasebusika, abanini bezithuthi ezisebenzisa umbane wonke badla ngokujongana nomceli mngeni: ukufudumeza ngaphakathi emotweni. Ngokungafaniyo nezithuthi ezisebenzisa umbane wonke, ezinokusebenzisa ubushushu obungasasebenziyo obuvela kwinjini ukufudumeza ikhabhathi, izithuthi ezisebenzisa umbane wonke wonke zifuna izixhobo zokufudumeza ezongezelelweyo. Iindlela zokufudumeza zemveli azisebenzi kakuhle okanye zidla amandla amaninzi, nto leyo echaphazela kakhulu uluhlu lwezithuthi. Ngoko ke, ngaba kukho isisombululo esibonelela ngokufudumeza ngokukhawuleza kunye nokusebenza kakuhle kwamandla? Impendulo ikuizifudumezi zamanzi ze-PTC ezine-voltage ephezulu.
I-PTC imele i-Positive Temperature Coefficient (PTC), oko kuthetha i-thermistor ye-positive temperature coefficient (PTC).Izifudumezi zePTC ezipholileyo ezine-voltage ephezuluSebenzisa iimpawu zee-thermistors ze-PTC, ezisebenza kwi-voltage ephezulu ukuguqula amandla ombane abe bubushushu ngokufanelekileyo, ngaloo ndlela zifudumeza i-coolant. Umgaqo wokusebenza weIzifudumezi zamanzi ze-PTCisekelwe kwinto yokuba ukumelana kwee-thermistors ze-PTC kuyanda njengoko ubushushu bunyuka. Xa umbane uhamba nge-thermistor ye-PTC, uyatshisa. Njengoko ubushushu bunyuka, ukumelana kuyakhula, kwaye umbane uyancipha, ngaloo ndlela kufezekiswa umda wobushushu ozenzekelayo, kuqinisekiswa ukhuseleko kunye nokusebenza kakuhle kwamandla.
Kwizithuthi zombane ezintsha ezisebenzisa amandla acocekileyo, umbane ophezulu ophuma kwibhetri yesithuthi usasazwa kwi-heater ye-PTC. Umbane uhamba nge-thermistor element ye-PTC, uyifudumeza ngokukhawuleza, nto leyo efudumeza i-coolant ehamba ngayo. Le coolant ishushu emva koko ithuthwa ngesihluzo samanzi ize ipompe iye kwitanki ye-heater yesithuthi. Emva koko i-heater isebenza, ivuthela ubushushu obuvela kwitanki ye-heater bungene kwikhabhinethi, inyusa ngokukhawuleza ubushushu bangaphakathi. Ezinye ze-coolant zingasetyenziselwa ukufudumeza ibhetri kwangaphambili, ukuqinisekisa ukusebenza kakuhle nakwiindawo ezinobushushu obuphantsi.
