Ku Fraunhofer Institute for Machine Tools and Forming Technology IWU, ofufuza akupanga ukadaulo wapamwamba wopanga injini zama cell amafuta ndi cholinga chothandizira kupanga kwawo mwachangu komanso kotsika mtengo. Kuti izi zitheke, ofufuza a IWU poyambilira akuyang'ana kwambiri pamtima pa injinizi ndipo akuyesetsa kupeza njira zopangira mbale za bipolar kuchokera kuzitsulo zopyapyala zachitsulo. Pa Hannover Messe, Fraunhofer IWU iwonetsa izi ndi zina zolonjeza zofufuza za injini yamafuta ndi galimoto yamtundu wa Silberhummel.
Pankhani yopereka mphamvu mumainjini amagetsi, ma cell amafuta ndi njira yabwino yowonjezeramo mabatire kuti awonjezere kuchuluka kwa magalimoto. Komabe, kupanga ma cell amafuta kumakhalabe njira yotsika mtengo, chifukwa chake pali mitundu yochepa yamagalimoto yomwe ili ndi ukadaulo woyendetsa uku pamsika waku Germany. Tsopano ofufuza a Fraunhofer IWU akugwira ntchito yotsika mtengo kwambiri: "Timatenga njira yonse ndikuyang'ana mbali zonse za injini yamafuta. Zimayamba ndi kuperekedwa kwa haidrojeni, zimakhudza kusankha kwa zipangizo zomwe zimakhudzidwa mwachindunji kupanga magetsi m'maselo amafuta, ndipo zimafikira ku thermoregulation mu selo lokha komanso m'galimoto yonse," akufotokoza Sören Scheffler, woyang'anira polojekiti ku Fraunhofer. IWU ku Chemnitz.
Monga gawo loyamba, ofufuza amayang'ana pamtima pa injini iliyonse yamafuta: "stack." Apa ndi pamene mphamvu imapangidwa m'maselo angapo osungidwa omwe amapangidwa ndi ma bipolar plates ndi electrolyte membranes.
“Tikufufuza momwe tingasinthire mbale wamba wa graphite bipolar ndi zitsulo zopyapyala. Izi zitha kupangitsa kuti ma stacks apangidwe mwachangu komanso mwachuma pamlingo waukulu ndipo zitha kukulitsa zokolola, "akutero Scheffler. Ofufuzawo akuyang'ananso za chitsimikizo cha khalidwe. Chigawo chilichonse m'miluwo chimawunikidwa mwachindunji pakupanga. Izi zimapangidwira kuti zitsimikizire kuti zigawo zokhazo zomwe zawunikiridwa bwino zimalowa mu stack.
Mofananamo, Fraunhofer IWU ikufuna kupititsa patsogolo luso la ma stacks kuti agwirizane ndi chilengedwe komanso momwe amayendetsera. Scheffler akufotokoza kuti, "Lingaliro lathu ndilakuti kusintha kosinthika kuzinthu zachilengedwe - mothandizidwanso ndi AI - kungathandize kupulumutsa haidrojeni. Zimapangitsa kusiyana ngati injini imagwiritsidwa ntchito pamtunda wapamwamba kapena wotsika kunja kwa kutentha, kapena ngati imagwiritsidwa ntchito m'zigwa kapena m'mapiri. Pakadali pano, ma stacks amagwira ntchito molongosoledwatu, osasunthika omwe salola kukhathamiritsa kwamtunduwu kumadalira chilengedwe. ”
Akatswiri a Fraunhofer adzawonetsa njira yawo yofufuzira ndi chiwonetsero chawo cha Silberhummel ku Hannover Messe kuyambira April 20 mpaka 24, 2020. Silberhummel imachokera ku galimoto yothamanga yomwe inapangidwa ndi Auto Union AG mu 1940s. Madivelopa a Fraunhofer IWU tsopano agwiritsa ntchito njira zatsopano zopangira kuti amangenso galimotoyi ndikupanga chiwonetsero chamakono chaukadaulo. Cholinga chawo ndikuveka Silberhummel ndi injini yamagetsi yozikidwa paukadaulo wapamwamba wamafuta. Ukadaulo uwu ukhala ukuwonetsedwa kale mugalimoto ku Hannover Messe.
Thupi la Silberhummel palokha ndi chitsanzo cha njira zatsopano zopangira ndi kupanga njira zomwe zikukulitsidwanso ku Fraunhofer IWU. Apa, komabe, cholinga chake ndi kupanga zotsika mtengo zamagulu ang'onoang'ono. Gulu la thupi la Silberhummel silinapangidwe ndi makina osindikizira akuluakulu okhudza ntchito yovuta ndi zida zachitsulo. M’malo mwake, nkhungu zoipa zopangidwa ndi matabwa osavuta kuzipanga zinali kugwiritsidwa ntchito. Makina opangira izi amakankhira gululo pa nkhungu yamatabwa pang'onopang'ono pogwiritsa ntchito mandrel apadera. Akatswiri amati njira imeneyi ndi "kuwonjezera". "Zimapangitsa kupangidwa mwachangu kwambiri kwa zigawo zomwe zimafunidwa kuposa njira wamba - kaya ma fender, ma hood kapena zigawo zam'mbali za tramu. Mwachitsanzo, kupanga zida zomwe zimagwiritsidwa ntchito popanga ziwalo za thupi zimatha kutenga miyezi ingapo. Tinkafunika patangotha sabata limodzi kuti tiyese—kuyambira kupanga nkhungu yamatabwa mpaka pagulu lomalizidwa,” akutero Scheffler.
Mutha kutsimikiziridwa kuti akonzi athu amayang'anitsitsa ndemanga zonse zomwe zatumizidwa ndipo adzachitapo kanthu. Malingaliro anu ndi ofunikira kwa ife.
Imelo yanu imagwiritsidwa ntchito podziwitsa wolandirayo amene watumiza imeloyo. Adilesi yanu kapena adilesi ya wolandila sizigwiritsidwa ntchito pazifukwa zina zilizonse. Zomwe mumalemba ziziwoneka mu imelo yanu ndipo sizisungidwa ndi Tech Xplore mwanjira iliyonse.
Tsambali limagwiritsa ntchito makeke kukuthandizani kuyenda, kusanthula momwe mumagwiritsira ntchito ntchito zathu, ndikupereka zomwe zili kuchokera kwa ena. Pogwiritsa ntchito tsamba lathu, mumavomereza kuti mwawerenga ndikumvetsetsa Mfundo Zazinsinsi ndi Migwirizano yathu.
