Ukubuka Konke Ngokuphathwa Kokushisa Ezinqolobaneni Zamandla Ezimoto Zikagesi

Ukuphathwa kokushisa kohlelo lwamandla ezimoto kuhlukaniswe ngokuphathwa kokushisa kohlelo lwamandla ezimoto zikaphethiloli zendabuko kanye nokuphathwa kokushisa kohlelo lwamandla ezimoto ezintsha zamandla. Manje ukuphathwa kokushisa kohlelo lwamandla ezimoto zikaphethiloli zendabuko sekuvuthiwe kakhulu. Imoto kaphethiloli yendabuko inikwa amandla yinjini, ngakho-ke injini Ukuphathwa kokushisa kugxile ekuphathweni kokushisa kwezimoto zendabuko. Ukuphathwa kokushisa kwenjini kuhlanganisa kakhulu uhlelo lokupholisa lwenjini. Ukushisa okungaphezu kuka-30% ohlelweni lwemoto kudinga ukukhishwa yisekethe yokupholisa injini ukuvimbela injini ekushiseni ngokweqile ngaphansi kokusebenza komthwalo omkhulu. I-coolant yenjini isetshenziselwa ukushisa ikhabini.

Isikhungo sikagesi sezimoto zikaphethiloli zendabuko sakhiwe ngezinjini kanye nokudluliselwa kwezimoto zikaphethiloli zendabuko, kuyilapho izimoto zamandla ezintsha zakhiwe ngamabhethri, ama-motor, kanye nezilawuli zikagesi. Izindlela zokuphatha ukushisa zalezi zinto ezimbili ziye zashintsha kakhulu. Ibhethri lamandla lezimoto zamandla ezintsha Ububanzi bokushisa obujwayelekile bokusebenza bungu-25 ~ 40℃. Ngakho-ke, ukuphathwa kokushisa kwebhethri kudinga kokubili ukuligcina lifudumele kanye nokulichitha. Ngesikhathi esifanayo, izinga lokushisa lemoto akufanele libe phezulu kakhulu. Uma izinga lokushisa lemoto liphezulu kakhulu, lizothinta impilo yenkonzo yemoto. Ngakho-ke, imoto idinga futhi ukuthatha izinyathelo ezidingekayo zokuchitha ukushisa ngesikhathi sokusebenzisa. Okulandelayo yisingeniso ohlelweni lokuphatha ukushisa lwebhethri kanye nohlelo lokuphatha ukushisa lokulawula kagesi kwemoto nezinye izingxenye.

Uhlelo lokuphatha ukushisa kwebhethri lamandla

Uhlelo lokuphatha ukushisa lwebhethri lamandla luhlukaniswe kakhulu ukupholisa umoya, ukupholisa uketshezi, ukupholisa izinto zokushintsha isigaba kanye nokupholisa ipayipi lokushisa ngokusekelwe ezindabeni zokupholisa ezahlukene. Izimiso kanye nezakhiwo zesistimu zezindlela ezahlukene zokupholisa zihlukile kakhulu.

1) Ukupholisa umoya webhethri elinamandla: iphakethe lebhethri kanye nomoya wangaphandle kuqhuba ukushintshana kokushisa okuguquguqukayo ngokugeleza komoya. Ukupholisa umoya ngokuvamile kuhlukaniswe ukupholisa kwemvelo kanye nokupholisa okuphoqelelwe. Ukupholisa kwemvelo yilapho umoya wangaphandle upholisa iphakethe lebhethri lapho imoto isebenza. Ukupholisa umoya okuphoqelelwe ukufaka ifeni yokupholisa okuphoqelelwe ngokumelene nephakethe lebhethri. Izinzuzo zokupholisa umoya ziphansi futhi kulula ukuzisebenzisa kwezentengiselwano. Okubi ukusebenza kahle kokushisa okuphansi, isilinganiso esikhulu sokusebenza kwesikhala, kanye nezinkinga ezinkulu zomsindo.(Isifudumezi Somoya se-PTC)

2) Ukupholisa uketshezi lwebhethri ngamandla: ukushisa kwephakethe lebhethri kususwa ukugeleza koketshezi. Njengoba amandla okushisa athile oketshezi makhulu kunomoya, umphumela wokupholisa wokupholisa uketshezi ungcono kunokupholisa umoya, futhi isivinini sokupholisa sishesha kakhulu kunesokupholisa umoya, futhi ukusatshalaliswa kwezinga lokushisa ngemva kokushabalaliswa kokushisa kwephakethe lebhethri kuyafana. Ngakho-ke, ukupholisa uketshezi nakho kusetshenziswa kabanzi kwezentengiselwano.(Isifudumezi Sokupholisa se-PTC)

3) Ukupholisa izinto zokushintsha isigaba: Izinto zokushintsha isigaba (PhaseChangeMaterial, PCM) zifaka i-paraffin, usawoti omanzi, ama-fatty acid, njll., angamunca noma akhiphe inani elikhulu lokushisa okucashile lapho kwenzeka ushintsho lwesigaba, kuyilapho izinga lokushisa lawo lingashintshi. Ngakho-ke, i-PCM inomthamo omkhulu wokugcina amandla okushisa ngaphandle kokusetshenziswa kwamandla okwengeziwe, futhi isetshenziswa kabanzi ekupholiseni ibhethri kwemikhiqizo kagesi efana namafoni aphathwayo. Kodwa-ke, ukusetshenziswa kwamabhethri kagesi ezimoto kusesesimeni socwaningo. Izinto zokushintsha isigaba zinenkinga yokuqhuba ukushisa okuphansi, okubangela ukuthi ubuso be-PCM obuthintana nebhethri buncibilike, kuyilapho ezinye izingxenye zingancibiliki, okunciphisa ukusebenza kokudlulisa ukushisa kwesistimu futhi akufaneleki kumabhethri kagesi amakhulu. Uma lezi zinkinga zingaxazululwa, ukupholisa kwe-PCM kuzoba yisisombululo sokuthuthukiswa esingaba khona kakhulu sokuphathwa kokushisa kwezimoto ezintsha zamandla.

4) Ukupholisa ipayipi lokushisa: Ipayipi lokushisa liyithuluzi elisekelwe ekudlulisweni kokushisa okushintsha isigaba. Ipayipi lokushisa liyisitsha esivaliwe noma ipayipi elivaliwe eligcwele indawo yokusebenza/uketshezi olugcwele (amanzi, i-ethylene glycol, noma i-acetone, njll.). Ingxenye eyodwa yepayipi lokushisa ukuphela kokuhwamuka, kanti enye ingxenye ukuphela ukuphela kokuqiniswa. Ayikwazi nje ukumunca ukushisa kwephakethe lebhethri kodwa futhi ifudumale iphakethe lebhethri. Njengamanje iyisistimu yokuphatha ukushisa yebhethri yamandla efanelekile kakhulu. Kodwa-ke, isacwaningwa.

5) Ukupholisa ngqo kwe-Refrigerant: ukupholisa ngqo kuyindlela yokusebenzisa umgomo we-R134a refrigerant nezinye izinto eziqandisayo ukuze ziphele futhi zimunce ukushisa, bese ufaka i-evaporator yesistimu yokupholisa umoya ebhokisini lebhethri ukuze upholise ibhokisi lebhethri ngokushesha. Uhlelo lokupholisa ngqo lusebenza kahle kakhulu ekupholiseni kanye nomthamo omkhulu wokupholisa.
