Njengoba umhlaba uqhubeka nokushintshela ezindleleni zokuhamba ezisimeme futhi ezinobungani nemvelo, izimoto zikagesi (ama-EV) ziya ngokuya zithandwa. Ukuze kwandiswe ukusebenza kahle futhi kuthuthukiswe ulwazi lokushayela, isici esibalulekile ukusebenza kahle kwe-coolant heater. Kulesi sihloko, sizohlola ubuchwepheshe obusha obuthathu be-coolant heater:Isifudumezi sokupholisa se-EV, i-HV coolant heater, kanye ne-PTC coolant heater.
Isifudumezi sokupholisa imoto kagesi:
Ama-heater e-EV coolant aklanyelwe ngqo izimoto zikagesi ukuze ahlinzeke ngokushisa okusebenzayo kohlelo lwe-coolant. Enye yezinzuzo eziyinhloko zalobu buchwepheshe ukuthi busebenza ngokuzimela ngaphandle kwenjini yokushisa yangaphakathi. Lokhu kusho ukuthi ngisho nasezimweni zezulu ezibandayo noma lapho imoto ingasetshenziswa, i-heater ye-coolant yemoto kagesi ingahlinzeka ngokushisa okukhululekile kwekhabhini, okuqinisekisa ukuqala okufudumele komshayeli nabagibeli.
Isifudumezi sokupholisa esinamandla aphezulu:
Ama-heater okupholisa ane-high-voltage (HV) asetshenziswa kakhulu ezimotweni zikagesi ezihlanganisiwe (PHEV) kanye nasezimotweni zikagesi ezinezandiso zebanga. I-heater yokupholisa ene-high-pressure ifudumeza kokubili uhlelo lokupholisa kanye negumbi labagibeli. Ngaphezu kwalokho, ingahlanganiswa nebhethri lemoto ukuze isetshenziswe kahle. Lobu buchwepheshe obuthuthukisiwe abugcini nje ngokuthuthukisa induduzo kodwa futhi buyasiza ekwandiseni ububanzi bukagesi bemoto.
Isifudumezi sokupholisa se-PTC:
Ama-heater e-coolant e-Positive Temperature Coefficient (PTC) asetshenziswa kabanzi ezimotweni zikagesi neze-hybrid ngenxa yokusebenza kahle kwazo kanye nezici zokuphepha ezinhle kakhulu. Ama-heater e-coolant e-PTC asebenza kusetshenziswa i-ceramic element elungisa ngokuzenzakalelayo ukumelana kwayo ngokusekelwe ekushiseni. Lokhu kusho ukuthi ilungisa ngokuzenzakalelayo ukuphuma kwamandla ngokwezidingo, iqinisekisa ukusetshenziswa kwamandla okuphumelelayo. Ngaphezu kwalokho, i-element ye-PTC iqinisekisa ukusatshalaliswa kokushisa okufanayo kulo lonke uhlelo lokupholisa, ivimbela noma yiziphi izindawo ezishisayo ezingadala umonakalo.
Ukuhlanganiswa kanye nezinzuzo:
Ukuhlanganiswa kwalezi zobuchwepheshe ze-heater ezithuthukisiwe kunikeza izinzuzo eziningi kubanikazi bezimoto zikagesi. Ukusebenza kahle kwamandla okuthuthukisiwe kuphumela ebangeni elide lokushayela ngoba amandla amancane ayachithwa ekufudumaleni uhlelo lwe-coolant. Ngokusebenzisa lezi zifudumezi, izimoto zikagesi zingasebenzisa ngokugcwele amandla agcinwe kumabhethri azo, ngaleyo ndlela zithuthukise ukusebenza kahle okuphelele.
Ngaphezu kwalokho, ngenxa yekhono lokushisa ikhabhini kusengaphambili, abashayeli nabagibeli bangajabulela ingaphakathi elikhululekile ngaphambi kokuqala uhambo lwabo. Lokhu akugcini nje ngokuqinisekisa isipiliyoni sokushayela esimnandi, kodwa futhi kunciphisa isidingo sokushisa okuvamile, okungaqeda ibhethri.
Ukuphepha kungenye isici esibalulekile esibhekwa yilobu buchwepheshe bokushisa. Njengoba izimoto zikagesi zivame ukudinga izikhathi ezinde zokufudumeza uma kubanda, ukusebenzisa lezi zifudumezi ezithuthukisiwe kuqinisekisa ukuthi izingxenye ze-drivetrain yemoto zisebenza kahle, kunciphisa ukuguguleka nokonakala ohlelweni.
Ekuphetheni:
Njengoba isidingo sezimoto zikagesi siqhubeka nokukhula, ukuthuthukisa ubuchwepheshe bokushisa obusebenzayo nobuphephile kuya ngokuya kuba yinto ebaluleke kakhulu. Ukuhlanganiswa kwe-heater ye-EV coolant, i-HV coolant heater kanyeIsifudumezi sokupholisa se-PTCkuthuthukisa induduzo, ukusebenza kahle kwamandla kanye nobubanzi bokushayela. Ngale ntuthuko, izimoto zikagesi kulindeleke ukuthi zibuse umkhakha wezokuthutha, zinikeze izixazululo zokuhamba ezizinzile nezintsha zekusasa eliluhlaza.
