【Ubuchwepheshe-Ukubambisana】 Uhlelo lokupholisa lokucwilisa olunezigaba ezimbili lwamathreyi ebhethri e-thermoplastic

Amathreyi ebhethri ahlanganisiwe e-Thermoplastic aseba ubuchwepheshe obubalulekile emkhakheni wezimoto ezintsha zamandla. Amathreyi anjalo afaka izinzuzo eziningi zezinto ze-thermoplastic, okuhlanganisa isisindo esincane, amandla aphezulu, ukumelana nokugqwala, ukuguquguquka komklamo, kanye nezakhiwo ezinhle kakhulu zemishini. Lezi zakhiwo zibalulekile ekuqinisekiseni ukuqina nokuthembeka kwamathreyi ebhethri. Ngaphezu kwalokho, uhlelo lokupholisa ephaketheni lebhethri le-thermoplastic ludlala indima ebalulekile ekugcineni ukusebenza kwebhethri, kwandise impilo yalo, kanye nokuqinisekisa ukusebenza okuphephile. Uhlelo lokuphatha ukushisa olusebenzayo luqinisekisa ukuthi ibhethri ligcinwa ngaphakathi kwebanga lokushisa elifunekayo ngaphansi kwazo zonke izimo zokusebenza, ngaleyo ndlela landisa ukusebenza kahle nokuphepha kwebhethri.

Njengobuchwepheshe obuvumela ukushaja okusheshayo, i-Kautex ikhombisa ukusetshenziswa kokupholisa kokucwilisa okunezigaba ezimbili, lapho iseli lokudonsa lisetshenziswa njenge-evaporator enkambisweni yokupholisa. Ukupholisa kokucwilisa okunezigaba ezimbili kufinyelela izinga lokudlulisa ukushisa eliphakeme kakhulu elingu-3400 W/m^2*K ngenkathi kukhulisa ukufana kwezinga lokushisa ngaphakathi kwephakethe lebhethri ekushiseni okusebenzayo kwebhethri okufanele. Ngenxa yalokho, uhlelo lokuphatha ukushisa kwebhethri lungaphatha ngokuphephile nangokuhlala njalo imithwalo yokushisa ngamazinga okushaja angaphezu kuka-6C. Ukusebenza kokupholisa kokupholisa kokucwilisa okunezigaba ezimbili kungavimbela ngempumelelo ukusabalala kokushisa ngaphakathi kwegobolondo lebhethri elihlanganisiwe le-thermoplastic, kanti ukupholisa kokucwilisa okunezigaba ezimbili okuqalisiwe kusabalalisa ukushisa endaweni ezungezile kufike ku-30°C. Umjikelezo wokushisa uyaguquguquka, okuvumela ukushisa okusebenzayo kwebhethri ezimweni ezibandayo. Ukusetshenziswa kokudlulisa ukushisa okubilayo okugelezayo kuqinisekisa ukudluliselwa kokushisa okuphezulu okuqhubekayo ngaphandle kokuwa kwebhamuza lomusi kanye nomonakalo olandelayo we-cavitation.

Emqondweni wokupholisa ukucwiliswa kwezigaba ezimbili kaKautex, uketshezi luthintana ngqo namaseli ebhethri ngaphakathi kwendlu yebhethri, okulingana ne-evaporator emjikelezweni wefriji. Ukucwiliswa kweseli kukhulisa ukusetshenziswa kwendawo engaphezulu kweseli ukudlulisa ukushisa, kuyilapho ukuhwamuka njalo koketshezi, okungukuthi ushintsho lwesigaba, kuqinisekisa ukufana okuphezulu kokushisa. I-schematic iboniswe kuMfanekiso 2.

Umfanekiso 2 Isimiso sokusebenza kokupholisa kokucwiliswa kwezigaba ezimbili

Umqondo wokuhlanganisa zonke izingxenye ezidingekayo zokusatshalaliswa koketshezi ngqo egobolondweni lebhethri elingasebenzisi ugesi, uthembisa ukuthi kuyindlela eqhubekayo. Lapho igobolondo lebhethri kanye nethileyi lebhethri kwenziwa ngezinto ezifanayo, kungahlanganiswa ndawonye ukuze kuqiniswe isakhiwo ngenkathi kususwa isidingo sezinto zokufaka i-capsulation futhi kwenziwe lula inqubo yokuvuselela.

Izifundo zibonise ukuthi indlela yokupholisa yokucwilisa enezigaba ezimbili esebenzisa i-SF33 coolant ikhombisa amakhono aphezulu okusabalalisa ukushisa ekudluliseni ukushisa kwebhethri. Lolu hlelo lugcine amazinga okushisa ebhethri ebangeni lika-34-35°C ngaphansi kwazo zonke izimo zokuhlola, okubonisa ukufana okuhle kakhulu kwezinga lokushisa. Ama-coolant afana ne-SF33 ahambisana nezinsimbi eziningi, amapulasitiki, nama-elastomer, futhi ngeke alimaze izinto zekhava lebhethri le-thermoplastic.

Isithombe 3 Ukuhlolwa kokulinganisa ukudluliselwa kokushisa kwephakethe lebhethri [1]

Ngaphezu kwalokho, ucwaningo lokuhlola luqhathanise amasu ahlukene okupholisa njengokufaka umoya endaweni yemvelo, ukufaka umoya endaweni ephoqelekile, kanye nokupholisa uketshezi nge-SF33 coolant, futhi imiphumela ibonise ukuthi uhlelo lokupholisa lokucwilisa olunezigaba ezimbili lwalusebenza kahle kakhulu ekugcineni izinga lokushisa leseli lebhethri.
Sekukonke, uhlelo lokupholisa olunezigaba ezimbili luhlinzeka ngesisombululo sokupholisa ibhethri esisebenza kahle nesifanayo sezimoto zikagesi nezinye izinhlelo zokusebenza ezidinga ukugcinwa kwamandla, okusiza ukuthuthukisa ukuqina nokuphepha kwebhethri.
