Cov qauv ntawm High-Power Aluminium-Cased Chargers
Mar 17, 2026| Aluminium-cased resistors, xws li cov kub kub- txhuas casing, daws cov teeb meem kub dissipation los ntawm kev tsim tshwj xeeb. Lub hauv paus ntsiab lus tseem ceeb nyob rau hauv kev siv lub siab thermal conductivity ntawm txhuas (kwv yees li 237 W / m·K) kom sai sai ua cov cua sov tsim tawm hauv lub resistor mus rau lub casing, uas ces dissipates nws los ntawm ib tug sab nraud kub dab dej los yog cua convection. Qhov no tiv thaiv tshav kub buildup thiab ua kom ruaj khov. Cov yam ntxwv tshwj xeeb muaj xws li:
Hlau Casing Encapsulation: Aluminium casing tsis tsuas yog muab kev tiv thaiv txhua yam tab sis kuj ua raws li qhov nruab nrab ntawm cov cua kub dissipation. Piv txwv li, hluav taws xob tsim los ntawm cov hlau- cov kab mob uas tsis muaj zog (ib yam khoom siv) sib npaug sib npaug los ntawm cov aluminium casing, txo qhov kub qhov chaw.
Cov ntaub ntawv thiab cov txheej txheem: Integrated encapsulation siv cov nplaim hluav taws-cov ntaub ntawv tsis muaj zog (xws li ceramics lossis silicates) txhim kho cov rwb thaiv tsev thiab kev co, tiv thaiv sab hauv vim kev co. Cov txheej txheem sib xyaw ua kom muaj kev sib koom ua ke nruj, txo cov thermal kuj.
Fais fab Load Design: Rated hwj chim ntau (xws li, 5 ~ 500W) yog ua tiav los ntawm optimizing cov kuj hlau ntoo khaub lig-sectional cheeb tsam thiab ntev, cia ua hauj lwm nyob rau hauv high tam sim no tsis overheating. Qhov kub coefficient (piv txwv li, ± 200ppm) qhia qhov℃uas tus nqi kuj hloov nrog kub; tus nqi qis dua pab tswj qhov tseeb.
Cov resistors no feem ntau muaj tsawg- tus yam ntxwv zaus (qis dua 100kHz), ua rau lawv haum rau DC los yog fais fab zaus daim ntawv thov, zam eddy tam sim no poob ntawm high zaus. Hauv kev sim tiag tiag, aluminium-cased resistors tuaj yeem txhim kho cov cua sov kom zoo dua li 30% piv rau cov resistors zoo tib yam, txuas ntxiv lawv lub neej kev pab cuam.
