I-PTCinkqubo yokufudumeza isifudumezi somoyayindlela eqhelekileyo yokufudumeza kwizithuthi ezintsha zamandla, ingakumbi kwizithuthi zombane ezicocekileyo. Ekubeni izithuthi zombane zingenawo ubushushu obungafunekiyo obuveliswa ziinjini zomlilo zangaphakathi, zifuna umbane ozimeleyoizisombululo zokufudumezaI-PTC sisifinyezo segama elithi "Positive Temperature Coefficient", esibhekisa kwi-positive temperature coefficient. Ukumelana kwale nto kuyanda ngokunyuka kobushushu.
Umgaqo wokusebenzaIsifudumezi somoya se-PTCkukusebenzisa olu phawu lwezinto ze-PTC ukuvelisa ubushushu ngokudlulisa umbane kwi-PTC element. Xa i-PTC element ishushu, ixabiso layo lokumelana liya kwanda ngokunyuka kobushushu, ngaloo ndlela kuncitshiswa ukunyuka okuqhubekayo kombane, kufezekiswe isiphumo sokuzilawula kwaye kugcinwe ubushushu obuphuma rhoqo. Le heater ineempawu zokonga amandla, ubushushu obuhlala buhleli, ukhuseleko kunye nobomi benkonzo ende.
Kwizithuthi ezintsha zamandla, ii-air heater ze-PTC zihlala zenziwe ngezinto ze-PTC, ii-heat sinks kunye nee-housings.Into ye-PTCyeyona nto iphambili enoxanduva lokufudumeza; isinki yobushushu isetyenziselwa ukukhupha ubushushu; indlu ikhusela isifudumezi ukuthintela iingozi ezifana nokutshayiswa ngumbane. Isifudumezi somoya se-PTC sinokufudumeza umoya ngokuthe ngqo okanye ngokungathanga ngqo ngokufudumeza isifudumezi. Indlela yokufudumeza umoya ngokuthe ngqo inesakhiwo esilula, kodwa kunokubakho iingozi zokhuseleko; indlela yokufudumeza umoya ngokuthe ngqo isebenzisa ipompo yesifudumezi ukupompa isifudumezi kwiradiator emotweni, kwaye isebenzisa ubushushu obuvela kwisifudumezi ukufudumeza umoya. Le ndlela ithintela ukungena kwezandi ezinkulu kunye neevolthi eziphezulu emotweni kwaye inokhuseleko oluphezulu, kodwa inkqubo iyinkimbinkimbi kwaye neendleko ziphezulu.
Iingenelo zezifudumezi zomoya ze-PTC ziquka ukumelana nobushushu obuphantsi, ukufudumeza ngokukhawuleza, i-voltage yokusebenza ebanzi, amandla azikhawulelayo, ubomi obude, kunye nokuvuthwa okuphezulu kwemveliso. Nangona kunjalo, iingxaki zayo nazo ziyabonakala, ikakhulu ukusetyenziswa kwamandla aphezulu, okunokunciphisa uluhlu lwezithuthi zombane. Ukongeza, ubushushu bomphezulu wezifudumezi ze-PTC buphezulu, obunokufudumala iiplastiki ezingqongileyo kwaye bukhuphe ivumba, ngoko ke kufuneka kunikwe ingqalelo ekhethekileyo xa kuyilwa indawo yokufaka isifudumezi.
Kwizicelo zokwenyani, inkqubo yokulawula ye-PTC air heater iya kulungisa amandla e-heater ngokweenkcukacha ze-sensor yobushushu emotweni ukuze ihlangabezane neemfuno zokukhululeka zabakhweli ngelixa inciphisa ukusetyenziswa kwamandla. Olu hlobo lwe-heater lusetyenziswa kakhulu kwizithuthi ezintsha zamandla, ingakumbi kwiimeko apho kufuneka ukufudumeza ngokukhawuleza kunye nokhuseleko oluphezulu.
