Ukubaluleka kwezimoto ezintsha zamandla uma kuqhathaniswa nezimoto zendabuko kubonakala kakhulu kulezi zici ezilandelayo: Okokuqala, ukuvimbela ukugoba kwezimoto ezintsha zamandla. Izimbangela zokugoba kwezimoto zifaka phakathi izimbangela zemishini nezikagesi (ukukhishwa kokushayisana kwebhethri, i-acupuncture, njll.) kanye nezimbangela ze-electrochemical (ukushaja ngokweqile kwebhethri nokuphuma ngokweqile, ukushaja okusheshayo, ukushaja okushisa okuphansi, i-internal short circuit eziziqalela zona, njll.). Ukugoba kwebhethri kuzobangela ibhethri lamandla ukuthi libambe umlilo noma liqhume, okusongela ukuphepha kwabagibeli. Okwesibili ukuthi izinga lokushisa elifanele lokusebenza kwebhethri lamandla lingu-10-30°C. Ukuphathwa kahle kwebhethri lokushisa kungaqinisekisa impilo yebhethri futhi kwandise impilo yebhethri yezimoto ezintsha zamandla. Okwesithathu, uma kuqhathaniswa nezimoto zikaphethiloli, izimoto ezintsha zamandla azinawo umthombo wamandla we-air-conditioner compressors, futhi azikwazi ukuthembela ekushiseni okungcolile okuvela enjinini ukuze kuhlinzekwe ukushisa ekhabini, kodwa zingaqhuba amandla kagesi kuphela ukulawula ukushisa, okuzonciphisa kakhulu ububanzi bokuhamba kwemoto entsha yamandla uqobo. Ngakho-ke, ukuphathwa kokushisa kwezimoto ezintsha zamandla sekuyisihluthulelo sokuxazulula imikhawulo yezimoto ezintsha zamandla.
Isidingo sokuphathwa kokushisa kwezimoto ezintsha zamandla siphakeme kakhulu kunesezimoto zikaphethiloli zendabuko. Ukuphathwa kokushisa kwezimoto ukulawula ukushisa kwemoto yonke kanye nokushisa kwendawo yonke, ukugcina ingxenye ngayinye isebenza ebangeni lokushisa elifanele, futhi ngesikhathi esifanayo kuqinisekiswe ukuphepha kanye nenduduzo yokushayela yemoto. Uhlelo lokuphathwa kokushisa kwezimoto ezintsha zamandla luhlanganisa kakhulu uhlelo lokupholisa umoya, uhlelo lokuphathwa kokushisa kwebhethri (I-HVCH), uhlelo lokuhlanganisa i-motor electronic control. Uma kuqhathaniswa nezimoto zendabuko, ukuphathwa kwe-thermal kwezimoto ezintsha zamandla kungeze amamojula okuphatha ukushisa okulawula ibhethri kanye ne-motor electronic control. Ukuphathwa kwe-thermal yezimoto zendabuko kuhlanganisa kakhulu ukupholisa injini kanye ne-gearbox kanye nokuphathwa kwe-thermal kwesistimu ye-air conditioning. Izimoto zikaphethiloli zisebenzisa i-air-conditioner refrigerant ukuhlinzeka ngokupholisa ikhabhini, ukushisa ikhabhini ngokushisa okungcolile okuvela enjinini, kanye nokupholisa injini kanye ne-gearbox ngokupholisa okuketshezi noma ukupholisa umoya. Uma kuqhathaniswa nezimoto zendabuko, ushintsho olukhulu ezimotweni ezintsha zamandla ngumthombo wamandla. Izimoto ezintsha zamandla azinazo izinjini zokuhlinzeka ngokushisa, futhi ukufudumala komoya okupholisa umoya kufezwa nge-PTC noma i-heat pump air conditioning. Izimoto ezintsha zamandla zinezidingo zokupholisa zamabhethri kanye nezinhlelo zokulawula ze-motor electronic, ngakho-ke ukuphathwa kwe-thermal kwezimoto ezintsha zamandla kuyinkimbinkimbi kakhulu kunezimoto zikaphethiloli zendabuko.
Ubunzima bokuphathwa kokushisa kwezimoto ezintsha zamandla buholele ekwenyukeni kwenani lemoto eyodwa ekuphathweni kokushisa. Inani lemoto eyodwa ohlelweni lokuphathwa kokushisa liphindwe kabili kuya kathathu kunemoto yendabuko. Uma kuqhathaniswa nezimoto zendabuko, ukwanda kwenani lezimoto ezintsha zamandla kuvela kakhulu ekupholiseni uketshezi lwebhethri, ama-air conditioner epompo yokushisa,Izifudumezi ze-PTC Coolant, njll.
Ukupholisa koketshezi kuthathe indawo yokupholisa umoya njengobuchwepheshe obujwayelekile bokulawula izinga lokushisa, futhi ukupholisa okuqondile kulindeleke ukuthi kufeze impumelelo kwezobuchwepheshe.
Izindlela ezine ezivamile zokuphatha ukushisa kwebhethri ukupholisa umoya, ukupholisa uketshezi, ukupholisa izinto zokushintsha isigaba, kanye nokupholisa okuqondile. Ubuchwepheshe bokupholisa umoya babusetshenziswa kakhulu kumamodeli okuqala, futhi ubuchwepheshe bokupholisa uketshezi buye baba yinto evamile kancane kancane ngenxa yokupholisa okufanayo kokupholisa uketshezi. Ngenxa yezindleko zabo eziphakeme, ubuchwepheshe bokupholisa uketshezi buhlonyiswe kakhulu ngamamodeli aphezulu, futhi kulindeleke ukuthi bungene kumamodeli aphansi esikhathini esizayo.
Ukupholisa umoya (Isifudumezi Somoya se-PTC) iyindlela yokupholisa lapho umoya usetshenziswa khona njengendawo yokudlulisa ukushisa, futhi umoya uthatha ngqo ukushisa kwebhethri ngefeni yokukhipha umoya. Ukuze kuphole umoya, kuyadingeka ukwandisa ibanga phakathi kwama-heat sink nama-heat sink phakathi kwamabhethri ngangokunokwenzeka, futhi iziteshi ezilandelanayo noma ezihambisanayo zingasetshenziswa. Njengoba uxhumano oluhambisanayo lungafeza ukushabalaliswa kokushisa okufanayo, iningi lezinhlelo zamanje ezipholiswe umoya zisebenzisa uxhumano oluhambisanayo.
Ubuchwepheshe bokupholisa uketshezi busebenzisa ukushintshana kokushisa kwe-convection ukuze kususwe ukushisa okukhiqizwa yibhethri futhi kuncishiswe izinga lokushisa lebhethri. I-liquid medium ine-coefficient ephezulu yokudlulisa ukushisa, umthamo omkhulu wokushisa, kanye nesivinini sokupholisa okusheshayo, okunomthelela omkhulu ekunciphiseni izinga lokushisa eliphezulu kanye nokuthuthukisa ukuhambisana kwensimu yokushisa yephakethe lebhethri. Ngesikhathi esifanayo, umthamo wohlelo lokuphatha ukushisa mncane kakhulu. Endabeni ye-thermal runaway precursors, ikhambi lokupholisa uketshezi lingathembela ekugelezeni okukhulu kwe-cooling medium ukuze liphoqe iphakethe lebhethri ukuthi lichithe ukushisa futhi lenze ukusatshalaliswa kokushisa phakathi kwamamojula ebhethri, okungacindezela ngokushesha ukuwohloka okuqhubekayo kwe-thermal runaway futhi kunciphise ingozi ye-runaway. Uhlobo lohlelo lokupholisa uketshezi luguquguquka kakhulu: amaseli ebhethri noma amamojula angacwiliswa oketshezini, iziteshi zokupholisa nazo zingasethwa phakathi kwamamojula ebhethri, noma ipuleti lokupholisa lingasetshenziswa phansi kwebhethri. Indlela yokupholisa uketshezi inezidingo eziphezulu ekungeneni komoya kohlelo. Ukupholisa izinto zokushintsha isigaba kubhekisela enqubweni yokushintsha isimo sezinto nokunikeza izinto zokushisa ezifihliwe ngaphandle kokushintsha izinga lokushisa, kanye nokushintsha izakhiwo zomzimba. Le nqubo izomunca noma ikhulule inani elikhulu lokushisa okucashile ukuze ipholise ibhethri. Kodwa-ke, ngemva kokushintsha kwesigaba okuphelele kwezinto zokushintsha isigaba, ukushisa kwebhethri akukwazi ukususwa ngempumelelo.
Indlela yokupholisa ngqo (ukupholisa ngqo kwefriji) isebenzisa umgomo wokushisa okucashile kokuhwamuka kwama-refrigerant (R134a, njll.) ukusungula uhlelo lokupholisa umoya emotweni noma ohlelweni lwebhethri, futhi ifaka i-evaporator yesistimu yokupholisa umoya ohlelweni lwebhethri, kanye ne-refrigerant ku-evaporator. I-Evaporate bese isusa ngokushesha nangokufanele ukushisa kwesistimu yebhethri, ukuze kuqedwe ukupholisa kwesistimu yebhethri.
