Isishwankathelo soLawulo lweThermal kwiiPowertrains zeZithuthi zoMbane

Ulawulo lobushushu lwenkqubo yamandla eemoto lwahlulwe lwaba lulawulo lobushushu lwenkqubo yamandla eemoto zemveli kunye nolawulo lobushushu lwenkqubo yamandla eemoto zemveli zamandla. Ngoku ulawulo lobushushu lwenkqubo yamandla eemoto zemveli zamafutha sele lukhulile kakhulu. Isithuthi samafutha semveli sisebenza ngenjini, ngoko ke injini Ulawulo lobushushu lugxininiso lolawulo lobushushu lweemoto zemveli. Ulawulo lobushushu lwenjini lubandakanya ikakhulu inkqubo yokupholisa yenjini. Ngaphezulu kwe-30% yobushushu kwinkqubo yemoto kufuneka ikhutshwe yisekethe yokupholisa yenjini ukuthintela injini ekutshiseni kakhulu xa isebenza ngomthwalo omkhulu. Isibandisi senjini sisetyenziselwa ukufudumeza ikhabini.

Isikhululo samandla sezithuthi zepetroli zemveli sakhiwe ziinjini kunye nokudluliselwa kwezithuthi zepetroli zemveli, ngelixa izithuthi zamandla ezintsha zenziwe ziibhetri, iimoto, kunye nolawulo lwe-elektroniki. Iindlela zolawulo lobushushu zezi zimbini ziye zatshintsha kakhulu. Ibhetri yamandla yezithuthi zamandla ezintsha Uluhlu lobushushu oluqhelekileyo lokusebenza yi-25 ~ 40℃. Ke ngoko, ulawulo lobushushu bebhetri lufuna ukuba ihlale ifudumele kwaye ichithe. Kwangaxeshanye, ubushushu bemoto akufuneki bube phezulu kakhulu. Ukuba ubushushu bemoto buphezulu kakhulu, buya kuchaphazela ubomi benkonzo yemoto. Ke ngoko, imoto nayo kufuneka ithathe amanyathelo afunekayo okusasaza ubushushu ngexesha lokusetyenziswa. Oku kulandelayo sisingeniso kwinkqubo yolawulo lobushushu bebhetri kunye nenkqubo yolawulo lobushushu yolawulo lwe-elektroniki lwemoto kunye nezinye izinto.

Inkqubo yolawulo lobushushu bebhetri yamandla

Inkqubo yolawulo lobushushu yebhetri yamandla yahlulwe ngokubanzi yaba kukupholisa umoya, ukupholisa ulwelo, ukupholisa izinto zokutshintsha isigaba kunye nokupholisa umbhobho wobushushu ngokusekelwe kwiimidiya ezahlukeneyo zokupholisa. Imigaqo kunye nolwakhiwo lwenkqubo yeendlela ezahlukeneyo zokupholisa zahlukile kakhulu.

1) Ukupholisa umoya ngebhetri enamandla: ipakethi yebhetri kunye nomoya wangaphandle ziqhuba utshintshiselwano lobushushu oluhambayo ngokuhamba komoya. Ukupholisa umoya ngokubanzi kwahlulwe phakathi kokupholisa kwendalo kunye nokupholisa okunyanzelekileyo. Ukupholisa kwendalo kuxa umoya wangaphandle upholisa ipakethi yebhetri xa imoto isebenza. Ukupholisa umoya okunyanzelekileyo kukufaka ifeni yokupholisa ngokunyanzelekileyo ngokuchasene nepakethi yebhetri. Iingenelo zokupholisa umoya zixabiso eliphantsi kunye nokusetyenziswa okulula kwezorhwebo. Iingxaki kukusebenza kakuhle kokusasaza ubushushu okuphantsi, umlinganiselo omkhulu wokusebenza kwendawo, kunye neengxaki ezinkulu zengxolo. (Isifudumezi soMoya sePTC)

2) Ukupholisa ulwelo lwebhetri ngamandla: ubushushu bepakethe yebhetri bususwa kukuhamba kolwelo. Ekubeni amandla athile obushushu bolwelo makhulu kunomoya, isiphumo sokupholisa ulwelo singcono kunesokupholisa umoya, kwaye isantya sokupholisa sikwakhawuleza kunesokupholisa umoya, kwaye ukusasazwa kobushushu emva kokutshatyalaliswa kobushushu bepakethe yebhetri kuyafana. Ke ngoko, ukupholisa ulwelo kukwasetyenziswa kakhulu kwezorhwebo.(Isifudumezi sePTC esipholileyo)

3) Ukuphola kwezinto zokutshintsha isigaba: Izinto zokutshintsha isigaba (PhaseChangeMaterial, PCM) ziquka iparafini, iityuwa ezimanzi, ii-fatty acids, njl.njl., ezinokufunxa okanye zikhuphe ubushushu obukhulu obufihlakeleyo xa kwenzeka utshintsho lwesigaba, ngelixa ubushushu bazo bungatshintshi. Ke ngoko, i-PCM inomthamo omkhulu wokugcina amandla obushushu ngaphandle kokusetyenziswa kwamandla okongezelelweyo, kwaye isetyenziswa kakhulu ekupholiseni iibhetri zeemveliso ze-elektroniki ezifana neefowuni eziphathwayo. Nangona kunjalo, ukusetyenziswa kweebhetri zamandla eemoto kusekwimeko yophando. Izinto zokutshintsha isigaba zinengxaki yokuqhuba ubushushu obuphantsi, okubangela ukuba umphezulu we-PCM odibana nebhetri unyibilike, ngelixa ezinye iindawo zinganyibiliki, okunciphisa ukusebenza kokudluliselwa kobushushu kwenkqubo kwaye akufanelekanga kwiibhetri zamandla ezinkulu. Ukuba ezi ngxaki zinokusonjululwa, ukupholisa i-PCM kuya kuba sisisombululo esinokwenzeka sophuhliso lolawulo lobushushu lwezithuthi zamandla amatsha.

4) Ukupholisa umbhobho wobushushu: Umbhobho wobushushu sisixhobo esisekelwe kutshintsho lobushushu lwesigaba. Umbhobho wobushushu sisitya esivaliweyo okanye umbhobho ovaliweyo ozaliswe yindawo yokusebenza/ulwelo olugcweleyo (amanzi, i-ethylene glycol, okanye i-acetone, njl.njl.). Elinye icandelo lombhobho wobushushu sisiphelo somphunga, kwaye elinye isiphelo sisiphelo somoya. Ayikwazi ukufunxa ubushushu bepakethi yebhetri kuphela kodwa ikwafudumeza ipakethi yebhetri. Okwangoku yeyona nkqubo ifanelekileyo yolawulo lobushushu bebhetri yamandla. Nangona kunjalo, isephantsi kophando.

5) Ukupholisa ngokuthe ngqo kwiRefrigerant: ukupholisa ngokuthe ngqo yindlela yokusebenzisa umgaqo we-R134a refrigerant kunye nezinye iifriji ukuze ziphele kwaye zifunxe ubushushu, kwaye ufake i-evaporator yenkqubo yokupholisa umoya kwibhokisi yebhetri ukuze ipholise ibhokisi yebhetri ngokukhawuleza. Inkqubo yokupholisa ngokuthe ngqo inokusebenza kakuhle kokupholisa kunye nomthamo omkhulu wokupholisa.
