Bridging-Droplet Thermal Diode txias Technology
Tsis ntev los no, cov kws tshawb fawb los ntawm Lub Tsev Kawm Ntawv ntawm Mechanical Engineering ntawm Virginia Tech hauv Tebchaws Meskas tau siv Vapor Chamber ob-theem thermal conductivity hauv paus ntsiab lus los tsim cov phiaj xwm Bridging Droplet Thermal Diode, uas muaj cov thermal conductivity 100 npaug ntawm qhov qub. Pab pawg Boreyko cia siab tias qhov kev hloov pauv hloov pauv hloov pauv hloov pauv hloov pauv hloov pauv hloov pauv hloov pauv hloov pauv ntawm cov phiaj xwm txheej txheem txheej txheem thermal diode yuav pab ua kom muaj peev xwm tswj xyuas cov khoom siv hluav taws xob, lub dav hlau, thiab lub dav hlau, thiab tuaj yeem ua txoj hauv kev tshiab rau kev tswj xyuas thermal ntawm cov chaw zov me nyuam thiab cov khoom siv hauv chaw.
Pab pawg Boreyko tau tsim cov thermal diode siv ob lub phaj tooj liab hauv qhov chaw kaw, sib cais los ntawm qhov sib txawv me me. Thawj lub rooj tsavxwm tau txais cov qauv wick kom khaws dej, thaum lwm lub rooj tsavxwm yog coated nrog cov dej tsis muaj dej (hydrophobic) txheej. Cov dej nyob rau saum npoo ntawm cov wick yog rhuab thiab evaporates rau hauv chav. Thaum cov ncu dhau los ntawm qhov khoob khoob, nws txias thiab condenses rau hauv cov dej ntws ntawm sab hydrophobic. Thaum cov tee dej no loj txaus los "kaw" qhov khoob, lawv tau nqus rov qab rau hauv lub tshuab nqus tsev, thiab cov txheej txheem pib dua.
Hauv kev siv cov tswv yim, lub hauv paus ntsiab lus ntawm kev ceev ceev unidirectional cua sov conduction ntawm planar bridging droplet thermal diodes yog tib yam li cov pav ca cua sov kav (tseem hu ua Vapor Chambers), uas tuaj yeem npog qhov kub ntawm cov khoom siv hluav taws xob xws li CPU chips, sai sai. tshem tawm cov cua sov, zam kom tsis txhob muaj cua sov ntawm cov nti tshaj qhov kev ua haujlwm kub txwv, thiab xyuas kom muaj kev nyab xeeb ntawm cov khoom siv hluav taws xob.
Thaum tshav kub kub yog siv rau cov dej absorbing phaj rov qab mus rau lub phaj hydrophobic, thiab cov chav condenses ntawm lub phaj hydrophobic thiab dhia thiab agglomerate rau ntawm superhydrophobic nto. Cov tee dej npog cov qhov khoob thiab tau nqus rov qab los ntawm cov kua dej nqus cov ntsiab lus, tswj kev hloov pauv ntawm ob-theem cua sov tsis cuam tshuam. Yog hais tias qhov chaw tshav kub nyob rau ntawm hydrophobic sab, cov cuab yeej no yuav tsis tsim cov pa vim tias cov dej tseem nyob hauv lub tshuab nqus dej. Yog vim li cas cov cuab yeej no tsuas tuaj yeem ua cua sov hauv ib qho kev taw qhia xwb.
