Zabwino kwambiri matenthedwe matenthedwe, coefficient olamulira a kukulitsa matenthedwe ndi chiyero chapadera chakuthupi. Zomveka bwino: Zogulitsa zathu zamagetsi zamagetsi zimakhala ndi mawonekedwe apadera kwambiri. Amagwiritsidwa ntchito ngati mbale zoyambira ndi zowulutsira kutentha, amatsimikizira kudalirika kwa zida zamagetsi.

Poyang'ana koyamba, mfundo yakuti zigawo zamagetsi zimapanga kutentha sizingawonekere kukhala zodetsa nkhawa. Masiku ano, pafupifupi mwana aliyense wasukulu angakuuzeni kuti mbali zina za kompyuta zimatenthedwa ikayatsidwa. Pamene chipangizochi chikugwira ntchito, gawo la mphamvu zamagetsi zomwe zimaperekedwa zimatayika ngati kutentha. Koma tiyeni tiyang'ane mozama: Kusintha kwa kutentha kungathenso kuwonetsedwa ngati kutentha kwapakati pa unit (ya) malo (kuchuluka kwa kutentha kwa kutentha). Monga zitsanzo zomwe zili mu graph zikuwonetseratu, kutentha kwa kutentha muzinthu zambiri zamagetsi kungakhale koopsa. Kukwera kwambiri ngati kukhosi kwa roketi komwe kumatentha mpaka 2 800 ° C kumatha kuwuka.

Coefficient ya kukula kwamafuta ndi chinthu china chofunikira kwa ma semiconductors onse. Ngati semiconductor ndi maziko a mbale zakuthupi zikuchulukira ndikulumikizana pamitengo yosiyana zikakumana ndi kusintha kwa kutentha ndiye kuti pamakhala zovuta zamakina. Izi zitha kuwononga semiconductor kapena kusokoneza kulumikizana pakati pa chip ndi chofalitsa kutentha. Komabe, ndi zida zathu, mukudziwa kuti muli m'manja otetezeka. Zida zathu zili ndi gawo lokwanira bwino pakukulitsa kutentha pakujowina ma semiconductors ndi zoumba.

Monga mbale zoyambira za semiconductor, mwachitsanzo, zida zathu zimagwiritsidwa ntchito pama turbine amphepo, masitima apamtunda ndi mafakitale. Mu ma module a semiconductor amphamvu a inverters (thyristors) ndi ma diode amphamvu, amagwira ntchito yofunika kwambiri. Chifukwa chiyani? Chifukwa cha kuchuluka kwawo kokwanira pakukulitsa matenthedwe komanso kusinthasintha kwamafuta, ma semiconductor base plates amapanga maziko olimba a semiconductor ya silicon ndikuwonetsetsa moyo wantchito wazaka zopitilira 30.

Zopangira kutentha ndi mbale zoyambira zopangidwa kuchokera ku molybdenum, tungsten, MoCu, WCu, Cu-Mo-Cu ndi Cu-MoCu-Cu laminates zimataya modalirika kutentha komwe kumapangidwa muzinthu zamagetsi. Izi zimalepheretsa kutenthedwa kwa zida zamagetsi ndikuwonjezera moyo wazinthu. Zofalitsa zathu zotentha zimathandiza kusunga malo ozizira, mwachitsanzo, mu ma modules a IGBT, phukusi la RF kapena tchipisi ta LED. Tapanga zida zapadera za MoCu zopangira mbale zonyamulira mu tchipisi ta LED. Izi zimakhala ndi coefficient of thermal expansion yofanana ndi safiro ndi zoumba.

Timapereka zopangira zathu zamagetsi zamagetsi ndi zokutira zosiyanasiyana. Amateteza zida kuti zisawonongeke ndikuwongolera kulumikizana kwa solder pakati pa semiconductor ndi zinthu zathu.
