Cov kua nplaum uas muaj cua sov feem ntau yog siv los txuas lub tshuab cua txias rau lub tshuab ua haujlwm lossis lub cim xeeb, txuas LEDs, thiab lwm yam rau lub heatsink nyob rau hauv rooj plaub uas siv cov thermal paste thiab fasteners tsis tsim nyog lossis ua tsis tau.
piav qhia khoom
Sab nraud, thermally conductive kua nplaum zoo li cov kua nplaum zoo li cov xim dawb ntawm homogeneous sib xws nrog yuav luag tsis muaj ntxhiab tsw. Nws yog muag nyob rau hauv ib lub raj nrog ib lub hau ntswj ntawm lub hau yas, uas tiv thaiv huab cua los ntawm kev nkag mus rau hauv lub raj thiab tso cai rau koj khaws cov kua nplaum ua kua. Thaum siv thawj zaug, nws yog ib qho tsim nyog yuav tsum tau tho qhov tshwj xeeb tiv thaiv txheej rau ntawm qhov kawg ntawm lub raj. Thaum rov siv dua, lub hau yooj yim unscrews kom nthuav tawm cov nplaum.
Cov kua nplaum yog siv los txuas cov cua kub ceev ntawm lub tshuab hluav taws xob ua hluav taws xob.
Qhov zoo ntawm cov kua nplaum
Lub zog thiab qhov ntom ntom thaum ziab kuj yog cov khoom zoo uas muaj los ntawm thermally conductive nplaum "Alsil". Tsis muaj qhov adhesion ntawm cov nplaum rau ntawm qhov chaw ua kom muaj kev sib txuas ruaj ntseg.
Kub-ua kua nplaum "Radial" yog muag hauv lub thawv ntim cuantim khoom uas muab kev tiv thaiv los ntawm ziab tawm rau lub sijhawm ntev. Xws li ntim nce lub txee lub neej ntawm cov nplaum. Qhov no yog qhov yooj yim heev, vim tias koj tsis tas yuav yuav lub raj tshiab txhua lub sijhawm yam tsis siv lub qub mus txog qhov kawg. Qhov no yog qhov zoo tshaj plaws ntawm "Radial" piv nrog cov khoom tsim los ntawm lwm cov tuam ntxhab.
Hais txog nws cov yam ntxwv, cov nplaum ua kom sov no zoo ib yam li Alsil.
Txhawm rau rhuav tshem cov khoom txuas nrog rau cov khoom siv hluav taws xob nrog cov nplaum no, siv rab riam maj mam txhuam qhov xav tau thiab tshem tawm, tom qab ntawd kho lossis hloov.
Tshav kub-conductive heatsink nplaum tau ua pov thawj nws tus kheej ua cov cuab yeej txhim khu kev qha thiab ntau yam rau kev txhim kho txawm tias cov LEDs muaj zog tshaj plaws thiab lwm qhov chaw.
Yuav ua li cas siv cov nplaum hloov hluav taws xob?
txheej txheem mounting diodes nrog kua nplaum muaj ob peb theem:
- Degrease txhua qhov chaw koj yuav ua haujlwm nrog kev siv cawv lossis acetone.
- Thov ib qho me me ntawm thermally conductive nplaum rau ntawm qhov chaw kom txias.
- Siv quab yuam, nias qhov kom txias rau saum npoo thiab sim ua kom muaj zog ncig kom sib npaug sib npaug faib cov nplaum rau tag nrho cov npoo ntawm qhov kom txias rau ntawm lub tshuab hluav taws xob.
- Kho nias rau 3-4 feeb kom zoo dua adhesion.
- Cia cov sib tov qhuav. Cov kua nplaum hardens tom qab 20 feeb, tab sis ua tiav ziab tshwm simtsuas yog hauv ib hnub xwb.
Ua-nws-koj tus kheej kub yaj nplaum nplaum?
Koj tuaj yeem tsim cov nplaum uas ua kom sov nrog koj txhais tes. Hauv tsab xov xwm no koj yuav pom cov lus qhia yooj yim tab sis muaj txiaj ntsig zoo ntawm yuav ua li cas rau koj tus kheej ua cov nplaum nplaum yog tias koj tsis muaj cov cuab yeej tshwj xeeb. Yog li, dab tsi yog txoj hauv kev zoo tshaj plaws los txuas cov khoom mus rau lub tshuab hluav taws xob yam tsis muaj kev puas tsuaj rau lub cev (nws yog ib qho tseem ceeb uas thermal conductivity yog tswj)?
Yuav kom tau txais lub zog muaj zog thermally conductive nplaum, koj yuav tsum muab 25 ml ntawm glycerin thiab 100 g ntawm txhuas oxide. Dej los ntawm glycerin yog evaporated los ntawm cua sov qhov sib tov mus rau qhov kub ntawm 200 degrees Celsius. Cov hmoov txhuas oxide kuj tau ua kom sov rau ob peb feeb, thaum tswj qhov kub ntawm 300 degrees Celsius. Tsuas yog tom qab xws li manipulations, cov khoom sib xyaw. Qhov tshwm sim yog lub khob noom cookie zoo li muab tshuaj txhuam, uas yog tsim los ntawm cov tshuaj tiv thaiv.
Lwm txoj hauv kev yooj yim los txuas diodes rau lub heatsink yog sib tov epoxy thiab thermal paste. Tab sis muaj cov xwm txheej thaum siv cov tshuaj nplaum thermal tsis tsim nyog, ces nws yog qhov zoo dua los siv tshwj xeeb npaj los yog yuav kub yaj nplaum nplaum.
