Saamaynta Hoos u dhigista Xakamaynta Xun ee Hadhuudhka Midab la'aanta iyo Ciladaadka Diidmada Kulaylka ee 6.35μm Aluminium Foil ee VR/AR Micro Heat Wess

1. Gogoldhig: Astaamaha Codsiga ee Foolka Aluminiumka ee Heat Heat-ka ee Qalabka VR/AR iyo Muhiimadda Xakamaynta Heerka Dhimista

Foornada aluminiumka ee weelasha kulaylka yar ee aaladaha VR/AR (ugu horrayn 1235/8079 loy, 6.35dhumuc weyn) Waxay u adeegtaa sidii qayb ka mid ah kala daadinta kulaylka xudunta u ah madaxa madaxa VR/AR, kantaroolayaasha, iyo aaladaha la midka ah. Sababtoo ah booska gudaha ee xaddidan ee aaladahaas (E.g., Mugga daloosha kulaylka ≤15cm³ gudaha madaxa madaxa VR), weelasha kulaylka waa in la yareeyaa (cabbirka 3-15mm) oo leh kulayl isku mid ah si looga fogaado kulaylka maxalliga ah - gaar ahaan maadaama awoodda kulaylku ay u dhaxayso 5-15W, u baahan faraqa heerkulka deegaanka ≤3℃.

Inta lagu jiro habka duubista, heerka dhimista (wadarta heerka dhimista = [(dhumucda hore – dhumucda ugu dambeysa)/dhumucda hore]×100%; heerka dhimista hal baas = [(dhumucda bilowga ah ee baska – dhumucda ugu dambeysa ee baaska)/dhumucda bilowga ah ee baska]×100%) waa halbeeg muhiim ah oo nidaaminaya kobcinta badarka. Marka loo fiiriyo 2024 VR/AR xogta warshadaha, 42% cilladaha kulaylka aaladaha waxay ka yimaadaan “kulaylka deegaanka ee weelasha kulaylka yar yar,” kaas oo laga heli karo xakamaynta heerka dhimista aan habboonayn aluminium foil kuleyliyaha yar yar ee qalabka VR/AR: ① Wadarta guud ee dhimista oo aan ku filnayn waxay sababtaa cabbirka badarka oo aan sinnayn, taasoo keenaysa 7W/(m · k) farqiga u dhexeeya kulaylka deegaanka ee weelka kulaylka; ② Isbeddelka xad dhaafka ah ee heerka dhimista hal-baas ayaa abuurta a “hadhuudh-dhuuban/qaran-qaran” isjiidjiid, samaynta aagagga dhintay kulaylka kala-baxa (farqiga heerkulka >5℃); ③ Heerarka hoos u dhaca aan sinnayn waxay keenaysaa kulaylka cidhifka ah, hoos u dhigista nolosha adeegga VR/AR qalabka chips by 20%.

Si wax looga qabto caqabadahaas, marka hore waa lagama maarmaan in la caddeeyo xiriirka ka dhexeeya heerka dhimista, Qaab dhismeedka hadhuudhka, iyo kulaylka conductivity-ka dhigida aas aaska aragtida ah ee rogid saxda ah ee noocan ah foil aluminium.

2. Xidhiidhka Aragtida Ee Ka Dhexeeya Heerka Dhimista, Qaab dhismeedka hadhuudhka, iyo Kuleylka kuleyliyaha loogu talagalay Foil Aluminium ee VR/AR Micro Heat Wessiga
