Cov khoom siv hluav taws xob yuav ua kom sov thaum lawv ua haujlwm. Yog tias cov cua sov tsis tuaj yeem dissipated rau lub sijhawm, qhov kub thiab txias yuav nce ntxiv. Thaum qhov kub thiab txias tshaj ib theem, cov khoom yuav ua tsis tiav los yog hlawv tawm. Yog li ntawd, nws yog ib qho tseem ceeb heev kom dissipate cua sov los ntawm cov khoom siv hluav taws xob. Rau cov khoom uas tuaj yeem nruab nrog cov dab dej kub, cov dab dej kub tuaj yeem ua lub luag haujlwm zoo heev hauv cov cua sov.

PCB pawg thawj coj saib muaj ntau yam khoom siv hluav taws xob uas yuav tsim kom muaj cua sov, yog li kev tswj xyuas thermal kom zoo hauv PCB tsim yuav pab tsim cov khoom lag luam txhim khu kev qha thiab kev lag luam. Hauv zos overheating ntawm PCB feem ntau ua rau ib nrab lossis txawm tias ua tiav ntawm lub cuab yeej. Thermal tsis ua hauj lwm txhais tau hais tias peb yuav tsum tau redesign lub PCB. Yuav ua li cas kom ntseeg tau tias cov txheej txheem tswj xyuas thermal raug siv los tiv thaiv koj lub rooj tsav xwm hauv Circuit Court, ntawm no yog 3 lub tswv yim los pab koj nrog koj cov haujlwm:

1, Tsim cov txheej txheem PCB rau kev faib hluav taws xob zoo

Ntau yam txheej txheem tsim PCB tuaj yeem siv los tswj kev faib cov cua sov yam tsis muaj nqi ntxiv. Nov yog qee cov tswv yim tsim qauv:

Cov khoom siv kub-rhiab heev yuav tsum tau muab tso rau hauv qhov chaw txias tshaj plaws (xws li hauv qab ntawm lub cuab yeej), tsis txhob ncaj qha los ntawm cov khoom siv hluav taws xob, zoo dua staggering ntau cov khoom tsim hluav taws xob ntawm lub dav hlau kab rov tav.

The heat sources on the same printed circuit board should be arranged as closely as possible according to the degree of heat output. The upstream of the cooling fan can place low heat-resistant components or parts (such as small signal transistors, small integrated circuits, electrolytic capacitors, etc.), while high heat-generating components or high heat resistance components (such as power transistors, large-scale integrated circuits, etc.) etc.) should be placed downstream of the cooling stream.

2, Lub ntsuas ntsuas kub yuav tsum tau muab tso rau hauv qhov chaw kub tshaj plaws rau qhov ntsuas kub kom raug.

Cheebtsam uas muaj lub zog siab tshaj plaws dissipation thiab cov zis hluav taws xob yuav tsum tau muab tso rau qhov twg cov cua sov dissipation yog qhov zoo tshaj plaws. Tsis txhob tso cov khoom kub kub rau ntawm cov ces kaum thiab cov npoo ntawm PCB tshwj tsis yog tias muaj lub dab dej kub nyob ze. Thaum nws los txog rau lub zog resistors, xaiv cov khoom loj kom ntau li ntau tau, thiab tso cai rau qhov chaw txaus rau cov cua sov thaum kho cov txheej txheem PCB.

Lub tshav kub dissipation ntawm ib tug ntaus ntawv yog loj nyob rau hauv lub airflow nyob rau hauv lub ntaus ntawv, yog li cov huab cua nyob rau hauv lub ntaus ntawv yuav tsum tau kawm nyob rau hauv lub tsim, thiab cov khoom los yog luam tawm Circuit Court boards yuav tsum tau positioned kom zoo.

Kab rov tav, cov khoom siv hluav taws xob siab yuav tsum tau muab tso rau ze rau ntawm ntug ntawm PCB li sai tau kom txo tau txoj kev hloov tshav kub. Nyob rau hauv txoj kev ntsug, qhov cuam tshuam ntawm huab cua reflections los yog cov ntsiab lus kub rhiab heev raug thaiv los ntawm cov khoom siab dua yuav tsum tau txiav txim siab. Rau cov khoom siv uas siv lub ntuj convection cua txias, nws yog qhov zoo tshaj plaws los npaj cov kev sib xyaw ua ke (lossis lwm yam khoom siv) hauv txoj kab ntsug lossis kab rov tav.

Tsis tas li ntawd, cov thermal pads thiab PCB vias tuaj yeem raug ntxiv los txhim kho thermal conductivity thiab txhawb kev hloov hluav taws xob mus rau thaj tsam loj. Lub thermal pads thiab vias yuav tsum nyob ze rau qhov chaw sov li sai tau. Lub vias tuaj yeem ua cua sov rau hauv av dav hlau ntawm sab nraud ntawm lub rooj tsavxwm, pab faib cov cua sov kom sib npaug thoob plaws PCB.

3, Ntxiv cov dab dej kub, cov kav dej kub, cov kiv cua rau cov khoom siv hluav taws xob siab

Yog tias muaj ob peb (3 lossis tsawg dua) cov khoom siv hluav taws xob tsim hluav taws xob ntawm PCB, koj tuaj yeem ntxiv lub dab dej kub rau cov khoom tsim hluav taws xob. Yog tias qhov ntsuas kub tsis tuaj yeem txo qis txaus, lub kiv cua tuaj yeem siv los txhim kho qhov txias. Thaum tus naj npawb ntawm cov khoom siv cua sov loj (ntau tshaj 3), lub dab da dej loj dua tuaj yeem siv tau, thiab lub dab dej loj dua tuaj yeem xaiv raws li txoj haujlwm thiab qhov siab ntawm cov khoom siv cua sov ntawm PCB, thiab raws li qhov sib txawv. qhov loj ntawm cov khoom, muaj kev cai dab dej kub. Rau PCB board daim npav, aluminium kub dab dej extrusion yog qhov kev siv thermal ntau tshaj plaws, raws li PCB board daim npav tshav kub dab dej yuav tsum tau ua haujlwm zoo thermal thiab yooj yim tsim, raws li ob lub ntsiab lus, 6063 aluminium alloy yog qhov kev xaiv zoo tshaj plaws rau lub dab dej kub extruded. , vim nws tsuas yog ua tau raws li ob qho xwm txheej no, tab sis kuj yog tus nqi zoo.

Extrusion yog dab tsi:

  Aluminium extrusion yog ib hom thav duab profile tau los ntawm cua sov ntawm txhuas pas nrig mus rau qhov tsim nyog kub thiab ces extrusion ua los ntawm ib tug nyuaj tooling.

Aluminium Extrusion heatsink yog ib qho yooj yim tshaj plaws thiab txuag nqi

thermal tov rau ntau daim ntawv thov TDP qis, los ntawm kev siv cov cuab yeej extrusion thiab CNC machining txheej txheem, peb tuaj yeem ua ntau txhiab tus dab dej sib txawv rau kev cai thiab kev cai ib nrab cua txias kev daws teeb meem.
