Copper Foil Diffusion Welded Flexible Connection: Technology & Applications
Jul 14, 2025
Cov ntawv ci tooj liab diffusion welded flexible kev twb kev txuas yog ib qho kev sib txuas hluav taws xob zoo tshaj plaws uas siv cov khoom siv -state diffusion bonding rau fuse ntau qhov siab -purity tooj liab ntawv ci txheej. Qhov no technology tsim metallurgical pob qij txha nrog exceptional conductivity (<0.5μΩ·m²), vibration resistance (>500k cycles), thiab peb -dimensional saj zawg zog (khoov vojvoog ntau dua los yog sib npaug rau 3D). Qhov zoo tshaj plaws rau siab - daim ntawv thov tam sim no, nws ua tau zoo tshaj qhov kev sib txuas ib txwm siv hauv tsheb hluav taws xob (400-800V roj teeb tshuab), lub zog khaws cia, thiab cov khoom siv hluav taws xob.
Nov yog ob peb tus kws txhais lus versions rau kev siv sib txawv:
Basic Structure and Process Principles
1. Cov qauv tsim qauv
Lub diffusion-bonded copper foil txuas txuas tau siv ntau txheej ntawm nyias tooj liab ntawv ci (feem ntau 0.05-0.3mm tuab ntshiab tooj liab lossis high-conductivity tooj liab alloy) ua cov khoom siv hauv paus. Tom qab qhov tseeb stacking, diffusion vuam hloov nws mus rau hauv ib tug hybrid qauv: rigid kev twb kev txuas xaus (rau kev ruaj ntseg davhlau ya nyob twg fixation) thiab ib tug saj zawg zog central lub cev muaj xws li cov ntaub ntawv sib koom ua ke.
2.Diffusion Vuam txheej txheem
Cov khoom no-lub xeev koom nrog thev naus laus zis ua rau muaj kev sib txawv ntawm atomic diffusion hla cov ntawv ci tooj liab cuam tshuam los ntawm kev tswj cov cua sov / siab (500-}700℃, 10-50MPa), tsim cov ntawv cog lus metallurgical yam tsis muaj cov hlau muab tub lim. Tsis zoo li brazing, tooj liab ntawv ci diffusion welded saj zawg zog kev twb kev txuas tswj lub hauv paus cov ntaub ntawv kev ncaj ncees-surface melting yog zam, khaws cia cov tooj liab intrinsic conductivity (<0.15 μΩ·m²) while eliminating interfacial resistance spikes common in conventional welding.
Cov yam ntxwv tseem ceeb
High conductivity
Qhov diffusion-copper foil txuas txuas tau yooj yim adopts siab -purity tooj liab ntawv ci (conductivity Ntau dua los yog sib npaug rau 98% IACS), thiab cov txheej txheem vuam diffusion zam qhov cuam tshuam ntawm vuam tsis xws luag ntawm kev ua tau zoo, ua kom muaj kev sib kis tau zoo tam sim no thiab tsis muaj zog poob.
Zoo heev Flexibility
Cov ntaub ntawv yooj yim tooj liab sib koom ua ke los ntawm diffusion vuam nta muaj ntau- txheej tooj liab ntawv ci hauv nruab nrab uas tuaj yeem hloov kho tau yooj yim, tiv taus kev co thiab cuam tshuam, thiab tuaj yeem hloov kho rau kev ua haujlwm xws li thermal expansion thiab contraction thiab vibration thaum lub sij hawm ua haujlwm, txo kev ntxhov siab ntawm cov khoom sib txuas.
Siab zog thiab kev ntseeg siab
Cov ntaub ntawv mos tooj liab diffusion-welded interconnect muaj lub zog siab (ze rau lub zog ntawm cov khoom siv hauv paus), zoo oxidation kuj thiab corrosion kuj. Nws tsis yooj yim rau kev xoob lossis kev sib cuag tsis zoo thaum lub sijhawm siv sijhawm ntev -, nrog rau lub neej kev pabcuam ntau dua 10 xyoo.
Customized Adaptability
Lawv tuaj yeem ua raws li qhov loj me, cov duab (xws li tiaj tus, tshwj xeeb - zoo li), thiab tam sim no - nqa peev xwm (los ntawm ntau pua amperes mus rau ntau txhiab amperes) raws li cov khoom yuav tsum tau, hloov mus rau kev sib txuas hluav taws xob xav tau hauv ntau qhov xwm txheej.
Cov kev hloov kho tseem ceeb:
Main Application Scenarios
1. Tshiab Zog Tsheb: Siv rau kev sib txuas ntawm cov khoom siv roj teeb, lub cev muaj zog, thiab cov tswj hwm, hloov mus rau qhov chaw vibration thaum lub tsheb khiav haujlwm.
2.Energy Storage Systems: Raws li cov khoom sib txuas ua ke rau cov roj teeb modules thiab cov thawv sib txuas, ua kom muaj kev ruaj ntseg ntawm cov dej ntws loj.
3. Cov khoom siv fais fab: Xws li kev hloov pauv hloov pauv hauv cov hloov pauv thiab hloov cov txee, hloov pauv mus rau qhov kub thiab txias thaum lub sijhawm ua haujlwm ntawm cov khoom siv.
4.Rail Transit: Siv nyob rau hauv traction systems ntawm high - ceev railways thiab subways rau saj zawg zog sib txuas nrog high voltage thiab loj tam sim no.
