switching fais fab mov thermal daws
Thaum tshav kub kub dissipation yog ib qho tseem ceeb rau kev ua haujlwm ruaj ntseg thiab txhim khu kev qha ntawm kev hloov fais fab adapter. Yog tias qhov kub thiab txias dhau lawm, qhov Performance index ntawm lub hwj huam mov yuav hloov, thiab txawm tias qhov tsis ua hauj lwm ntawm lub hwj chim adapter yuav tshwm sim. Yog li ntawd, lub luag haujlwm tseem ceeb ntawm kev tsim cov cua sov dissipation yog los tswj qhov kub thiab txias kom nws tsis pub dhau qhov kev txwv ntawm kev ntseeg tau.
Tnws cov khoom ntawm lub zog hloov hluav taws xob hloov pauv muaj qee qhov kev xav tau rau kev ua haujlwm kub. Yog tias qhov kub thiab txias tshaj nws qhov kev txwv, nws yuav ua rau muaj kev hloov pauv ntawm kev ua haujlwm ntawm lub zog hluav taws xob, kom cov khoom siv hluav taws xob tsis tuaj yeem ua haujlwm ruaj khov thiab ntseeg tau, ua rau nws lub neej ua haujlwm luv, thiab tseem ua rau cov khoom siv hluav taws xob puas tsuaj.
Yog li ntawd, peb yuav tsum tau them sai sai rau lub thermal tsim ntawm lub hwj huam mov hloov, hauv qab no yog ib co tsim cov ntsiab lus rau siv thaum tsim cov thermal tov rau cov khoom siv:
1. Xaiv cov heatsink. Lub hauv paus ntsiab lus ntawm kev xaiv heatsink yog xaiv lub heatsink nrog lub ntim me me thiab lub teeb yuag kom deb li deb tau ntawm qhov chaw ua kom muaj cua sov txaus, thiaj li txuag tau qhov chaw sab hauv thiab txo tag nrho qhov hnyav ntawm lub hwj chim adapter.
2. Kev teeb tsa ntawm cov heatsink. Thaum txhim kho lub heatink, txoj kev teeb tsa nrog cov cua sov me me thiab thermal kuj yuav tsum raug xaiv kom deb li deb tau.
3. Txo qhov thermal tsis kam ntawm lub interface. Qhov saum npoo ntawm lub heatsink yuav tsum tiaj tus thiab du, siv nrog silicone roj lossis cov khoom siv hluav taws xob los txo qhov kev sib cuag thermal ntawm lub tshuab hluav taws xob thiab lub zog semiconductor.
4. Heatsink nto kho. Txhawm rau kom cov hluav taws xob muaj peev xwm ntawm lub heatsink, qhov saum npoo ntawm lub heatsink tuaj yeem coated nrog ib txheej ntawm cov hluav taws xob hluav taws xob siab coefficient xws li xim dub lossis oxide. Lub radiator nrog dub txheej yuav tsum nyiam thiab cov txheej yuav tsum tau tiv thaiv los ntawm kev puas tsuaj.
5. Kev teeb tsa txoj haujlwm ntawm lub zog semiconductor. Lub hwj chim semiconductor yuav tsum tau nruab rau hauv nruab nrab ntawm lub heatsink, kom lub heatsink tuaj yeem ua kom sov sib npaug thiab txhim kho cov cua sov kom zoo.
6. Txoj hauj lwm ntawm heatsink. Lub heatsink yuav tsum nyob rau hauv kev sib cuag ncaj qha nrog cov cua ntws tawm sab nraum lub hwj chim mov kom deb li deb tau kom txo tau qhov kub ntawm ambient. Nyob rau tib lub sijhawm, cov nyhuv ntawm convective tshav kub hloov ntawm radiator tuaj yeem txhim kho.
