Isishwankathelo soLawulo lwe-Thermal kwii-Powertrains zesiThuthi soMbane

Ulawulo lwe-thermal yenkqubo yamandla e-automotive yahlulwe kulawulo lwe-thermal yenkqubo yamandla yezithuthi zesiqhelo kunye nolawulo lwe-thermal yenkqubo yamandla yemoto entsha.Ngoku ulawulo lwe-thermal yenkqubo yamandla yemoto yesiqhelo yemoto ikhulile kakhulu.Isithuthi samafutha esintu sinikwa amandla yi-injini, ngoko ke ulawulo lwe-injini ye-Thermal lugxininiso lolawulo lobushushu lwemoto.Ulawulo lwe-thermal ye-injini ikakhulu lubandakanya inkqubo yokupholisa ye-injini.Ngaphezulu kwe-30% yobushushu kwinkqubo yemoto kufuneka ikhutshwe yi-injini yokupholisa isekethe ukukhusela i-injini ekutshiseni phantsi komthwalo ophezulu.Isisipholisi se-injini sisetyenziselwa ukufudumeza indlwana.

Amandla ombane wezithuthi zemveli zepetroli akhiwe ngeenjini kunye nokuhanjiswa kwezithuthi zamafutha emveli, ngelixa iimoto zamandla amatsha zenziwe ngeebhetri, iimoto kunye nolawulo lwe-elektroniki.Iindlela zokulawula ukushisa kwezi zibini ziye zatshintsha kakhulu.Ibhetri yamandla ezithuthi zamandla amatsha Uluhlu oluqhelekileyo lobushushu obusebenzayo yi-25～40℃.Ke ngoko, ulawulo lwe-thermal yebhetri lufuna zombini ukuyigcina ishushu kwaye iyichithe.Ngexesha elifanayo, ubushushu bemoto akufanele bube phezulu kakhulu.Ukuba ubushushu bemoto buphezulu kakhulu, kuya kuchaphazela ubomi benkonzo yemoto.Ke ngoko, i-motor ikwadinga ukuthatha amanyathelo ayimfuneko okuphelisa ubushushu ngexesha lokusetyenziswa.Oku kulandelayo kukwazisa kwinkqubo yolawulo lwe-thermal yebhetri kunye nenkqubo yolawulo lwe-thermal yolawulo lwe-motor electronic kunye namanye amacandelo.

Inkqubo yokulawula ukushisa kwebhetri yamandla

Inkqubo yolawulo lwe-thermal yebhetri yamandla yahlulahlulwe ikakhulu kukupholisa umoya, ukupholisa ulwelo, ukupholisa izinto zesigaba sokutshintsha kunye nokupholisa umbhobho wobushushu ngokusekelwe kumajelo ahlukeneyo okupholisa.Imigaqo kunye nezakhiwo zenkqubo yeendlela ezahlukeneyo zokupholisa zahluke kakhulu.

1) Ukupholisa umoya kwebhetri yamandla: ipakethi yebhetri kunye nomoya wangaphandle uhambisa utshintshiselwano lobushushu ngokuhamba komoya.Ukupholisa komoya kwahlulahlulwe ngokubanzi kukupholisa kwendalo kunye nokupholisa ngenkani.Ukupholisa ngokwendalo kuxa umoya wangaphandle upholisa ipakethe yebhetri xa imoto ibaleka.Ukupholisa umoya ngenkani kukufakela ifeni yokupholisa ngenkani kwibhetri.Iinzuzo zokupholisa umoya zixabiso eliphantsi kunye nesicelo sorhwebo esilula.Izinto ezingeloncedo kukuchitha ubushushu obuphantsi, umlinganiselo wokuhlala kwindawo enkulu, kunye neengxaki ezimandundu zengxolo.(Isifudumezi-moya se-PTC)

2) Ukupholisa ulwelo lwebhetri yamandla: ubushushu bebhetri buthathwa kukuhamba kolwelo.Kuba ubushushu obuthile bomthamo wolwelo bukhulu kunomoya, isiphumo sokupholisa sokupholisa ulwelo singcono kuneso sokupholisa komoya, kwaye isantya sokupholisa sikwakhawuleza kuneso sokupholisa komoya, kunye nokuhanjiswa kobushushu emva kokutshatyalaliswa kobushushu. ibhetri pack ifana.Ke ngoko, ukupholisa ulwelo nako kusetyenziswa ngokubanzi kurhwebo.(Isifudumezi esiPholisayo se-PTC)

3) Ukupholisa izinto zokutshintsha isigaba: Izinto zokutshintsha iSigaba (PhaseChangeMaterial, PCM) ziquka iparafini, i-hydrated salts, i-fatty acids, njl., ezinokuthi zifunxe okanye zikhulule ubushushu obuninzi obufihliweyo xa utshintsho lwesigaba lusenzeka, ngelixa ubushushu babo buhlala buhlala. engatshintshanga.Ke ngoko, i-PCM inomthamo omkhulu wokugcina amandla obushushu ngaphandle kokusetyenziswa kwamandla okongeziweyo, kwaye isetyenziswa kakhulu ekupholiseni ibhetri yeemveliso zombane ezifana neeselfowuni.Nangona kunjalo, ukusetyenziswa kweebhetri zamandla emoto kusekho kwimeko yophando.Izinto zokutshintsha iSigaba zinengxaki ye-thermal conductivity ephantsi, ebangela ukuba ubuso be-PCM edibene nebhetri bunyibilike, ngelixa ezinye iindawo zinganyibiliki, ezinciphisa ukusebenza kobushushu benkqubo kwaye ayifanelekanga kumandla amakhulu. iibhetri.Ukuba ezi ngxaki zinokusonjululwa, ukupholisa kwe-PCM kuya kuba sesona sisombululo sophuhliso lolawulo lwe-thermal yezithuthi zamandla amatsha.

I-4) Ukupholisa umbhobho wokushisa: Umbhobho wokufudumala sisixhobo esisekelwe kwisigaba sokutshintsha ukutshintshwa kobushushu.Umbhobho wokushisa isitya esivaliweyo okanye umbhobho otywiniweyo ogcwele i-saturated medium medium / liquid (amanzi, i-ethylene glycol, okanye i-acetone, njl.).Elinye icandelo lombhobho wobushushu lisiphelo somphunga, kwaye esinye isiphelo sisiphelo se-condensation.Ayinakufunxa kuphela ubushushu bepakethi yebhetri kodwa iphinde ifudumale ipakethe yebhetri.Ngoku iyeyona nkqubo ifanelekileyo yolawulo lobushushu bebhetri.Nangona kunjalo, isaphantsi kophando.

I-5) Ukupholisa ngokuthe ngqo kwe-refrigerant: ukupholisa ngokuthe ngqo kuyindlela yokusebenzisa umgaqo we-R134a wefriji kunye nezinye iifriji ukuze zikhuphe kwaye zifake ubushushu, kwaye ufake i-evaporator ye-air conditioning system kwibhokisi yebhetri ukupholisa ngokukhawuleza ibhokisi lebhetri.Inkqubo yokupholisa ngokuthe ngqo inokusebenza kakuhle kokupholisa kunye nomthamo omkhulu wokupholisa.
