Kuvumbulutsa Chinsinsi cha Kuchita kwa Silicone Thermal Pad: Zinthu Zisanu Zazikulu Zomwe Zimatsimikizira Kutentha kwa Matenthedwe

Pamene zida zamagetsi zikupita patsogolo kuti zigwire ntchito zapamwamba komanso zazikulu zing'onozing'ono, kutaya kutentha kwakhala chinsinsi chachikulu cholepheretsa kupita patsogolo kwaukadaulo. Monga chinthu chofunikira pakuwongolera matenthedwe, the Thermal Conductivity wamapepala otentha a siliconemwachindunji amatsimikiza kutentha kutaya mphamvu. Ndiye, ndi zinthu ziti zomwe zimayendetsa ntchito yovutayi? Nkhaniyi, yomwe ikujambula pa kafukufuku wamakampani, ikupereka kusanthula mozama kwa zinthu zisanu zomwe zimalimbikitsa komanso malingaliro asayansi kumbuyo kwawo.

1. Filler Properties: "Skeleton" ya Thermal Path

Mtundu wa filler, zomwe zili, komanso kugawa ndizinthu zazikulu zomwe zimakhudza magwiridwe antchito a mapepala otentha a silicone. Kafukufuku wasonyeza kuti kwambiri thermally Woyendetsa zodzaza monga alumina ndi boron nitride zimatha kupanga njira yabwino yopangira kutentha kudzera mukubalalitsidwa kofanana. Mwachitsanzo, ngati ndevu kapena ma fibrous fillers alumikizidwa, matenthedwe amatenthedwe amatha kupitilira 30%. Komabe, kuwonjezera ma filler mopitilira muyeso kumatha kuchepetsa kusinthasintha kwa zinthu ndikuwonjezera kukana kwamafuta.

2. Kutentha ndi Chinyezi: Mavuto Awiri a Zosintha Zachilengedwe. Kutentha

conductivity wa mapepala otentha a siliconesi static. M'malo otentha kwambiri, zida zina zimatha kukalamba, zomwe zimapangitsa kuti ma network azitha kusweka. Kutentha kwakukulu, kumbali ina, kungapangitse chodzaza kuti chitenge chinyezi, kuchepetsa kutentha kwa kutentha. Chifukwa chake, m'malo otentha kwambiri komanso okhala ndi chinyezi chambiri, monga mapaketi amagetsi agalimoto yamagetsi, osinthidwa.zinthu za siliconendi kumafunika kupirira nyengo.

2. Kapangidwe Kapangidwe: Luso Lolinganiza Makulidwe ndi Kupsinjika

Makulidwe ndi lupanga lakuthwa konsekonse kwa matenthedwe matenthedwe. Ngakhale kuonda kwambiri kumatha kufupikitsa mtunda wowongolera kutentha, kungayambitse kudzaza kosakwanira. Kunenepa kwambiri kumatha kukulitsa kukana kwamafuta ndikufooketsa mphamvu yakuchotsa kutentha. Kuphatikiza apo, magwiridwe antchito a compression ndi ofunikira - kulimba mtima kwabwino kumatsimikizira kukwanira kolimba ngakhale pansi pa kupanikizana kwanthawi yayitali, kuletsa mipata ya mpweya kuti isapangike kukana kutentha.

3. Gawo laling'ono ndi Njira: Kuwongolera Molondola pamlingo wa Molecular

Chiyero cha silikoni gawo lapansi ndi kusanganikirana kumakhudza mwachindunji kufanana kwa kubalalitsidwa kwa filler. Kusakwanira kokonzekera bwino kungayambitse kudzikundikira kwamafuta, kutsekereza matenthedwe. Kuphatikiza apo, mapangidwe omatira a gawo lapansi (monga zomatira zodziyimira pawokha) amafunikira kukhazikika pakati pa kumasuka ndi kukana kutentha. Zina zomatira zimatha kuwonjezera kukana kwamafuta mpaka 20%.

5. Zochitika Zogwiritsira Ntchito: Kufananiza Yeniyeni kuchokera ku Chiphunzitso mpaka Kuchita

High matenthedwe madutsidwe si panacea. Akatswiri amakampani akuwonetsa kuti zomwe zimafunikira pakutentha kwa madalaivala a LED ndi zamagetsi ogula zimasiyana kwambiri, zomwe zimafunikira kuganiziridwa mozama kwa kutentha kwapang'onopang'ono, mtengo wake, ndi chitetezo (monga kukana kwamagetsi ndi kuwunika kwamoto). Mwachitsanzo, mapaketi a batire amphamvu nthawi zambiri amafunikira matenthedwe apamwamba kuposa 5W/mK, pomwe zida zamagetsi zamagetsi zimangofunika 1-3W/mK.

6. Zamtsogolo

Ndi kufalikira kwa zida zamtundu wachitatu za semiconductor, mapepala otentha a siliconeZikukulirakulira kutengera kusinthasintha kwamafuta (> 10W/mK), kukana kutsika kwamafuta, komanso kuwonda kwambiri (pansi pa 0.1mm). Kugwirizana kwatsopano muzinthu za sayansi ndi zamakono zamakono zidzapitiriza kupereka njira zothetsera mavuto omwe akukumana nawo ndi zipangizo zamagetsi.
