Chotenthetsera Choziziritsira cha NF Group 10KW 800V Chotenthetsera Choziziritsira cha HVCH EV

Chotenthetsera chopyapyala ndi chapamwambachotenthetsera choziziritsira chamagetsi champhamvuChopangidwa makamaka ngati chotenthetsera magalimoto amagetsi. Chopangidwa pogwiritsa ntchito njira zina zotulutsira nthunzi ndi njira zina zochokera ku semiconductor, chimayika bwino zigawo zingapo zogwira ntchito pa substrate yopyapyala kwambiri, ndikupanga chinthu chotenthetsera cholimba kwambiri chokhala ndi kufanana komanso kulimba bwino. Chimapereka mphamvu yofulumira ya kutentha, kufika kutentha komwe mukufuna mkati mwa masekondi.

Poyerekeza ndi ma heater a PTC achikhalidwe, ukadaulo wa thin-film umapereka mphamvu yomveka bwino. Ma heater a PTC amataya mphamvu mwachibadwa pamene kukana kumawonjezeka ndi kutentha, zomwe zimapangitsa kuti mphamvu zichepe komanso kutayika. Mosiyana ndi zimenezi, ma heater a thin-film amakhala ndi mphamvu yokhazikika ya 96–97% pa ntchito zosiyanasiyana. Amathandizira kulamulira mphamvu molondola kudzera mu PWM ndipo sapanga mphamvu yolowera nthawi yoyambira, kuteteza zamagetsi zomwe zimakhala zovuta. Ubwino wawo waukulu ndikugwirizana bwino ndi nsanja za high-voltage: zimathandizira 400V mpaka 1000V, zomwe zimapitirira malire a mayunitsi a PTC, omwe ndi ofunikira pa zomangamanga za 800V. Kuphatikiza apo, alibe lead komanso alibe nthaka, ndipo mtengo wawo tsopano ndi wofanana ndi wa PTC. Izi zimatsimikizira kuti magwiridwe antchito nthawi zonse pansi pa katundu wosiyanasiyana.

Pogwiritsidwa ntchito moyenera, chipangizochi chimagwira ntchito ngatichotenthetsera choziziritsira batri, kusunga batire pa 20–45 °C kuti isunge nthawi ndi moyo.Chotenthetsera chamadzimadzi cha EV, imatenthetsa nyumba mwachangu ndikutseka mawindo m'malo ozizira. Imagwiranso ntchito ngati chotenthetsera cha kutentha koyambira kuzizira.chotenthetsera chamadzi chamagetsi okweraChifukwa chake ndi gawo lofunikira kwambiri pakuwongolera kutentha kwa magalimoto amagetsi.

Monga bwenzi lodalirika, Hebei Nanfeng Automobile Equipment (Group) Co., Ltd, yomwe idakhazikitsidwa mu 1993, ndi kampani yamagulu yokhala ndi mafakitale asanu ndi limodzi. Ndife ogulitsa otsogola a zida zatsopano zamagetsi ku China komanso ogulitsa magalimoto ankhondo aku China. Zinthu zathu zazikulu zimaphatikizapo chotenthetsera choziziritsira chamagetsi champhamvu,pompu yamadzi yamagetsi, BTMS, compressor yamagetsi ya mpweya, EPS, EHPS, compressor yamagetsi ya mpweya woziziritsa, valavu ya njira zitatu, chotenthetsera malo oimika magalimoto, chotenthetsera malo oimika magalimoto, ndi chosinthira kutentha kwa mbale. Posachedwapa, Nanfeng Group yatulutsa mndandanda wa zotenthetsera zopyapyala za 10 kW. Timalandila mafunso kuchokera kwa makasitomala atsopano ndi omwe alipo.
