Thermal Design rau kev ua haujlwm siab GPU heatsink

Tam sim no, thaum qhov kev ua tau zoo ntawm daim npav daim npav tau nce ntxiv, qhov teeb meem ntawm kev siv hluav taws xob thiab hluav taws xob hluav taws xob tau dhau los ua qhov tseem ceeb. Ntawm cov tswv tsev PC, daim npav daim npav tau dhau los ua cov khoom siv nrog cov khoom siv hluav taws xob loj tshaj plaws, thiab cov heatsink ntawm daim npav daim npav tau dhau los ua qhov loj thiab loj dua. Tam sim no, ntau tshaj 90% ntawm cov radiators siv cov yeeb nkab thiab cov fin welded structural heatsinks.

Heatpipe tsim:

Ntxiv nrog rau qhov tsim nyog cov yeeb nkab kub dabtsi yog khoov, feem ntau cov kav dej kub yuav tsum tau tsim kom ncaj raws li qhov ua tau, thiab qhov kev khoov yog qhov me me. Qhov ncaj los ntawm cov yeeb nkab cua sov tsim yog qhov zoo dua hauv kev ua kom sov dissipation. Kev khoov ntau dhau ua rau cov thermal tsis kam thiab txo cov cua sov ua kom zoo. Tsis tas li ntawd, raws li kev ua tau zoo ntawm cov heatsink module, nws tseem yog ib qho tseem ceeb kom xaiv cov yeeb nkab sib txawv ntawm qhov sib txawv, qhov ntev, flattening thickness thiab sab hauv ntawm cov yeeb nkab kub.

Cov khoom siv tooj liab pab nqus cua sov sai dua:

Qhov tshwj xeeb kub muaj peev xwm ntawm tooj liab yog siab dua li ntawm txhuas, stainless hlau thiab lwm yam ntaub ntawv. Yog li ntawd, lub peev xwm nqus cua sov ntawm tooj liab yog zoo dua li ntawm lwm cov khoom siv hlau. Kev sib ntxiv ntawm cov khoom siv tooj liab kom zoo hauv kev tsim cov duab daim npav heatsink yuav pab tau qhov kev ua tau zoo tag nrho. Lub hauv paus ntshiab tooj liab yog nyob rau hauv kev sib cuag nrog cov duab daim npav core kom nqus tau cov cua sov tawm los ntawm daim npav daim npav. Thaum tshav kub kub yog pauv mus rau aluminium puag phaj, fins thiab cov kav dej kub, thiab cov cua kub dissipation yog nrawm nrog kev pab los ntawm kev quab yuam convection cua txias.

Fin stack thiab soldering txheej txheem:

Ntxiv nrog rau qhov zoo thiab kev npaj ntawm cov kav dej kub, lwm qhov tseem ceeb hauv kev ua haujlwm zoo thermal yog qhov kev siv ntawm cov fins. Rau lub tshuab hluav taws xob, nws yog ib qho uas coj cov cua sov los ntawm GPU core. Yuav ua li cas coj cov cua sov los ntawm qhov kawg ntawm cov yeeb nkab cua sov mus rau cov fins yog qhov txuas tseem ceeb heev. Yog hais tias lub tshav kub conduction tsis ua kom zoo, ces cov cua sov yeeb nkab efficiency yog tsis muaj txiaj ntsig.

Feem ntau, reflow soldering thev naus laus zis yuav siv ncaj qha rau vuam cov yeeb nkab thiab cov fins, uas yuav ua rau cov yeeb nkab kub thiab cov fins haum zoo dua thiab txhim kho cov cua sov ua kom zoo. Cov txheej txheem tsim cov cai ntawm "zipper fin" yog siab heev. Yog tias cov txheej txheem tsim khoom tsis zoo, qhov tsis sib xws ntawm cov fins, lossis cov fins ib leeg tsis haum nrog cov yeeb nkab cua sov, tag nrho cov cua kub dissipation kev ua tau zoo ntawm heatsink module yuav cuam tshuam zoo heev.

Vim qhov nce ntxiv ntawm kev ua haujlwm zaus ntawm cov tub ntxhais ntawm GPU thiab kev ua haujlwm zaus ntawm cov duab cim xeeb, lub peev xwm cua sov ntawm GPU kuj nce nrawm. Tus naj npawb ntawm transistors nyob rau hauv cov zaub nti tau mus txog lossis txawm tias dhau tus lej hauv CPU. Xws li qib siab ntawm kev sib xyaw ua ke yuav ua rau muaj kev nce ntxiv hauv cov nqi calorific. Txhawm rau daws cov teeb meem no, cov kev daws teeb meem zoo tshaj plaws yog qhov tsim nyog rau kev tsim GPU txias.
