Heat Pipe Heat Sink Performance
Thaum tshav kub kub dab dejyog tsim los ntawm sealing raj, suction core thiab chav channel. Lub tshuab nqus tsev yog nyob ib puag ncig ntawm phab ntsa ntawm lub raj kaw thiab impregnated nrog cov kua dej tsis haum. Cov kua tuaj yeem yog dej distilled, ammonia, methanol lossis acetone. Cov yeeb nkab kub kub lub dab dej uas muaj cov kua dej xws li ammonia, methanol thiab acetone tseem muaj peev xwm ua kom sov tau zoo ntawm qhov kub thiab txias.
Thaum lubcov yeeb nkab cua sov dab dejyog khiav, nws evaporation seem absorbs lub tshav kub generated los ntawm lub tshav kub qhov chaw (lub hwj chim semiconductor ntaus ntawv, thiab lwm yam), ua rau cov kua nyob rau hauv nws wick boil rau chav. Lub rhuab chav txav los ntawm evaporating seem ntawm lubcua sov yeeb nkab cua sov dab dejmus rau nws qhov chaw txias, qhov twg nws condenses rau hauv cov kua. Cov kua condensed yog tom qab ntawd rov qab mus rau ntu evaporation los ntawm kev ua haujlwm capillary ntawm lub tshuab nqus tsev rau ntawm phab ntsa, thiaj li ua rau rov ua dua cov txheej txheem saum toj no ntawm kev ua kom sov tas li.
Cov kav dej kub muaj qhov ua tau zoo heev thermal conductivity. Thaum cov khoom siv hluav taws xob xws li txhuas, tooj liab, graphite thiab pob zeb diamond muaj cov thermal conductivity xws li 250 W / m•K txog 1,500 W / m•K, cov kav dej kub muaj cov thermal conductivity zoo li ntawm 5, 000 W / m •K txog 200,000 W/m•K. Cov kav dej kub hloov cov cua sov los ntawm qhov chaw cua sov (evaporator) mus rau lub dab dej kub (condenser) dhau qhov kev ncua deb dhau los ntawm cov cua sov latent ntawm vaporization ntawm cov kua ua haujlwm. Cov kav dej kub feem ntau muaj 3 ntu: ntu evaporator (cov khoom siv hluav taws xob / qhov chaw), adiabatic (lossis thauj) ntu thiab ntu condenser (cov khoom cua sov / dab dej).
Heat Tube Heat Sink Qhov zoo:
· Thermal teb ceev ceev
· Lub teeb nyhav
· High tshav kub dissipation efficiency
· Tsis xav tau kev siv hluav taws xob sab nraud
· Zoo isothermal
· Kev nyab xeeb thiab txhim khu kev qha ua haujlwm
PowerWinx yog cov khoom siv hluav taws xob ua hluav taws xob ua hluav taws xob nrog cov thev naus laus zis thev naus laus zis, tab tom nrhiav cov yeeb nkab cua sov los yog ua ntej thermal daws, thov hu rau peb.
