Ukubaluleka kwezithuthi zamandla amatsha xa kuthelekiswa nezithuthi zemveli zibonakaliswa ikakhulu kule miba ilandelayo: Okokuqala, thintela ukubaleka kwe-thermal kwizithuthi zamandla amatsha.Izizathu zokubaleka kwe-thermal zibandakanya oomatshini kunye nezizathu zombane (i-bettery collision extrusion, i-acupuncture, njl.) kunye nezizathu ze-electrochemical (ibhetri engaphezulu kwebhetri kunye nokukhutshwa, ukutshaja ngokukhawuleza, ukutshaja okuphantsi kobushushu, i-self-initiated internal short circuit, njl.).Ukubaleka kwe-thermal kuya kubangela ukuba ibhetri yamandla ibambe umlilo okanye ide iqhume, ibeka isoyikiso kukhuseleko lwabakhweli.Okwesibini kukuba ubushushu obuphezulu bokusebenza kwebhetri yamandla yi-10-30 ° C.Ulawulo oluchanekileyo lwe-thermal yebhetri inokuqinisekisa ubomi benkonzo yebhetri kwaye yandise ubomi bebhetri yezithuthi zamandla amatsha.Okwesithathu, xa kuthelekiswa neenqwelo zamafutha, izithuthi zamandla amatsha azinawo amandla ombane we-air-conditioning compressors, kwaye azikwazi ukuthembela ekushiseni kwenkunkuma ukusuka kwi-injini ukubonelela ukushisa kwi-cabin, kodwa zinokuqhuba kuphela amandla ombane ukulawula ukushisa, okuya kunciphisa kakhulu. uluhlu lokuhamba ngemoto entsha yamandla ngokwayo.Ngoko ke, ulawulo lwe-thermal yezithuthi zamandla amatsha luye lwaba sisitshixo sokusombulula imiqobo yezithuthi zamandla amatsha.
Imfuno yolawulo lwe-thermal yezithuthi zamandla amatsha iphezulu kakhulu kuneyemoto yemveli.Ulawulo lwe-Automotive thermal kukulawula ubushushu besithuthi sonke kunye nobushushu bendalo yonke, gcina icandelo ngalinye lisebenza kuluhlu olufanelekileyo lobushushu, kwaye kwangaxeshanye uqinisekise ukhuseleko kunye nokuqhuba induduzo yemoto.Inkqubo yolawulo olushushu lwesithuthi samandla esitsha ikakhulu ibandakanya inkqubo yokupholisa umoya, inkqubo yolawulo lobushushu bebhetri (HVCH), inkqubo yendibano yolawulo lweemoto.Xa kuthelekiswa neemoto zemveli, ulawulo lwe-thermal yezithuthi zamandla amatsha zongeze ibhetri kunye neemodyuli zolawulo lwe-electronic control thermal.Ulawulo olushushu lweemoto lwemveli ikakhulu lubandakanya ukupholisa kwe-injini kunye nebhokisi yegiya kunye nolawulo lwe-thermal yenkqubo yokupholisa umoya.Izithuthi zamafutha zisebenzisa i-air-conditioning refrigerant ukunika ukupholisa kwikhabhin, ukufudumeza indlwana ngobushushu obumdaka obusuka enjini, kunye nokupholisa i-injini kunye nebhokisi yegiya ngokupholisa ulwelo okanye ukupholisa umoya.Xa kuthelekiswa nezithuthi zemveli, utshintsho olukhulu kwizithuthi zamandla amatsha ngumthombo wamandla.Izithuthi zamandla amatsha azinazo ii-injini zokubonelela ubushushu, kwaye ukufudumeza kwe-air conditioning kwenziwa nge-PTC okanye i-heat pump air conditioning.Izithuthi zamandla amatsha zongeze iimfuno zokupholisa iibhetri kunye neenkqubo zolawulo lwe-elektroniki, ngoko ke ulawulo lwe-thermal yezithuthi zamandla amatsha lunzima ngakumbi kunezithuthi zemveli zamafutha.
Ubunzima bokulawulwa kwe-thermal yezithuthi zamandla amatsha kuye kwaqhuba ukunyuka kwexabiso lemoto enye ekulawuleni i-thermal.Ixabiso lesithuthi esisodwa kwinkqubo yokulawula i-thermal ngamaxesha angama-2-3 kwimoto yendabuko.Xa kuthelekiswa neemoto zemveli, ukongezwa kwexabiso lezithuthi zamandla amatsha ikakhulu livela kulwelo lwebhetri ukupholisa, impompo yobushushu umoya conditioners,Izifudumezi ezipholileyo ze-PTC, njl.
Ukupholisa ulwelo kuthathe indawo yokupholisa komoya njengetekhnoloji yokulawula ubushushu obuqhelekileyo, kwaye ukupholisa ngokuthe ngqo kulindeleke ukuba kuphunyezwe impumelelo yetekhnoloji.
Iindlela ezine eziqhelekileyo zolawulo lobushushu bebhetri kukupholisa komoya, ukupholisa ulwelo, ukupholisa imathiriyeli yokutshintsha kwesigaba, kunye nokupholisa ngokuthe ngqo.Itekhnoloji yokupholisa umoya yayisetyenziswa kakhulu kwiimodeli zokuqala, kwaye itekhnoloji yokupholisa ulwelo ngokuthe ngcembe ibe yeyona nto iphambili ngenxa yokupholisa okufanayo kokupholisa ulwelo.Ngenxa yexabiso layo eliphezulu, itekhnoloji yokupholisa ulwelo ubukhulu becala ixhotyiswe ngeemodeli eziphezulu, kwaye kulindeleke ukuba izike kwiimodeli eziphantsi kwixesha elizayo.
Ukupholisa umoya (Isifudumezi-moya se-PTC) yindlela yokupholisa apho umoya usetyenziswa njengesixhobo sokudlulisa ubushushu, kwaye umoya ususa ngokuthe ngqo ubushushu bebhetri nge fan yokuphuma.Ukupholisa umoya, kuyimfuneko ukwandisa umgama phakathi kweendawo zokutshisa ukushisa kunye neendawo zokutshisa ukushisa phakathi kweebhetri kangangoko kunokwenzeka, kwaye i-serial okanye i-parallel channels ingasetyenziswa.Ekubeni uxhulumaniso oluhambelanayo lunokufezekisa ukutshatyalaliswa kobushushu obufanayo, uninzi lweenkqubo ezipholileyo zomoya zangoku zifumana uxhulumaniso oluhambelanayo.
Itekhnoloji yokupholisa ulwelo isebenzisa ukutshintshiselana kobushushu obumanzi ukususa ubushushu obuveliswa yibhetri kunye nokunciphisa ubushushu bebhetri.I-liquid medium ine-coefficient yokudlulisa ukushisa okuphezulu, umthamo omkhulu wokushisa, kunye nesantya sokupholisa ngokukhawuleza, esinempembelelo ebalulekileyo ekunciphiseni ubushushu obuphezulu kunye nokuphucula ukuhambelana kwentsimi yobushushu bepakethi yebhetri.Ngexesha elifanayo, umthamo wenkqubo yokulawula i-thermal uncinci.Kwimeko ye-thermal runaway precursors, isisombululo sokupholisa ulwelo sinokuthembela ekuhambeni okukhulu kwendawo yokupholisa ukunyanzela ipakethi yebhetri ukuba ikhuphe ubushushu kwaye iqonde ukuhanjiswa kobushushu phakathi kweemodyuli zebhetri, ezinokucinezela ngokukhawuleza ukuwohloka okuqhubekayo kokubaleka kwe-thermal kunye nokunciphisa ubushushu. umngcipheko wokubaleka.Ifom yenkqubo yokupholisa ulwelo iguquguquka ngakumbi: iiseli zebhetri okanye iimodyuli zinokuntywiliselwa kumanzi, iziteshi zokupholisa nazo zingasetwa phakathi kweemodyuli zebhetri, okanye ipleyiti yokupholisa ingasetyenziselwa phantsi kwebhetri.Indlela yokupholisa ulwelo ineemfuno eziphezulu kwi-airtightness yenkqubo.Ukupholisa kwemathiriyeli yokutshintsha kwesigaba kubhekiselele kwinkqubo yokutshintsha imeko yenkqu kunye nokubonelela ngemathiriyeli yobushushu obufihlileyo ngaphandle kokutshintsha ubushushu, kunye nokutshintsha iimpawu ezibonakalayo.Le nkqubo iyakufunxa okanye ikhuphe ubushushu obukhulu obufihlakeleyo ukupholisa ibhetri.Nangona kunjalo, emva kokutshintshwa kwesigaba esipheleleyo sokutshintsha kwesigaba, ukushisa kwebhetri akunakuthathwa ngokufanelekileyo.
Indlela yokupholisa ngokuthe ngqo (i-refrigerant direct cooling) isebenzisa umgaqo wobushushu obungafihliyo be-evaporation yeefriji (i-R134a, njl. njl.) ukuseka inkqubo yokupholisa umoya kwisithuthi okanye kwinkqubo yebhetri, kwaye ifakela i-evaporator ye-air conditioning system kwibhetri. inkqubo, kunye nefriji kwi-evaporator I-Evaporator kwaye ngokukhawuleza nangokufanelekileyo isuse ubushushu benkqubo yebhetri, ukuze igqibezele ukupholisa kwenkqubo yebhetri.
