Thermal Design ntawm Semiconductor Cheebtsam hauv Electronic Devices
Hauv kev tsim cov khoom siv hluav taws xob, nws ib txwm tsim nyog los daws cov teeb meem xws li miniaturization, efficiency, thiab EMC (electromagnetic compatibility). Nyob rau hauv xyoo tas los no, thermal countermeasures rau semiconductor Cheebtsam tau nce nqi, thiab thermal tsim ntawm semiconductor Cheebtsam tau dhau los ua lub ntsiab lus tshiab. Vim nws txoj kev koom tes hauv kev ua tau zoo, kev ntseeg siab, thiab kev nyab xeeb ntawm cov khoom siv thiab cov khoom siv, "tshav kub" yeej ib txwm yog ib qho ntawm cov kev tshawb fawb tseem ceeb.
Semiconductor Cheebtsam qhia meej qhov siab tshaj plaws tus nqi Tjmax ntawm cov nti kub hauv pob, uas yog qhov sib txuas kub. Thaum lub sij hawm tsim, nws yog ib qho tsim nyog yuav tsum tau kawm txog kev tsim hluav taws xob thiab qhov kub thiab txias kom ntseeg tau tias qhov sib txuas kub ntawm cov khoom tsis tshaj Tjmax. Yog li ntawd, thermal xam yuav ua rau tag nrho cov semiconductor Cheebtsam kom paub meej tias yog Tjmax tau dhau lawm. Yog tias nws muaj peev xwm ua tau siab tshaj Tjmax, kev ntsuas yuav tsum tau ua kom txo qis lossis tawg kom sov kom Tjmax nyob rau hauv qhov siab tshaj plaws. Hauv luv, qhov no yog thermal tsim.
Rau cov khoom siv hluav taws xob, cov kev xav tau rau miniaturization thiab kev ua haujlwm siab tau dhau los ua ntuj tsim, yog li txhawb kev sib koom ua ke ntxiv. Tshwj xeeb, nws yog manifested raws li ib tug ntau dua ntawm cov Cheebtsam, ntau dua installation ceev ntawm Circuit Court boards, thiab lub plhaub me me. Qhov tshwm sim yog ib qho tseem ceeb ntawm cov cua kub ceev. Kev tsim hluav taws xob tau dhau los ua qhov tseem ceeb vim nws pab txhim kho cov cuab yeej kev ntseeg siab, kev nyab xeeb, thiab txo nqi tag nrho.
Yog tias qhov kev tsim thermal tsis ua tib zoo ua tiav thiab cov kev ntsuas tsis raug coj los siv thaum lub sijhawm tsim qauv, cov teeb meem tshwm sim los ntawm cov cua sov yuav raug tshawb pom thaum lub sij hawm cov khoom mus sim ntau lawm lossis txawm tias ua ntej ntau lawm. Txawm hais tias peb tsis xav xav txog cov teeb meem tshwm sim los ntawm tshav kub, kev kho cua sov tsis zoo tuaj yeem ua rau muaj teeb meem cuam tshuam txog kev nyab xeeb ntawm tus kheej xws li haus luam yeeb, hluav taws, thiab hluav taws. Yog li ntawd, thermal tsim yog qhov tseem ceeb heev. Yog li ntawd, nws yog ib qho tsim nyog yuav tsum ua tau zoo ua cov thermal tsim los ntawm qhov pib theem.
