Puas Stainless Hlau Thermos Khob Puas Muaj Kev Tiv Thaiv Thaum Kub Kub?

Stainless hlau thermos flasks muaj cov khoom cua sov zoo.

 

Lub tshav kub tuav ua haujlwm ntawm stainless hlau thermos flasks feem ntau yog nyob ntawm lawv cov qauv tsim tshwj xeeb thiab kev siv thev naus laus zis. Lawv feem ntau siv ob - txheej stainless hlau qauv nrog lub tshuab nqus tsev nruab nrab ntawm ob txheej, ua rau lub tshuab nqus tsev rwb thaiv tsev. Qhov kev tsim no zoo thaiv peb txoj hauv kev tseem ceeb ntawm kev hloov hluav taws xob: hluav taws xob, convection, thiab conduction.

 

Radiation: Thermal radiation yog txheej txheem ntawm tshav kub propagating nyob rau hauv daim ntawv ntawm electromagnetic tsis. Lub tshuab nqus tsev nyob rau hauv stainless hlau thermos flask txo qhov kev hloov ntawm thermal hluav taws xob vim hais tias yuav luag tsis muaj teeb meem nyob rau hauv lub tshuab nqus tsev ib puag ncig kom nqus los yog emit thermal tawg.

 

Convection: Convection yog cov txheej txheem ntawm kev hloov hluav taws xob los ntawm kev txav macroscopic ntawm cov kua (xws li cua lossis dej). Nyob rau hauv ib lub thermos stainless hlau fwj, lub tshuab nqus tsev txheej tshem tawm cov muaj kua xws li cua, yog li tiv thaiv thermal convection.

 

Kev coj ua: Kev coj ua yog txheej txheem ntawm kev hloov hluav taws xob los ntawm kev sib tsoo ntawm cov khoom siv microscopic hauv ib yam khoom. Txawm hais tias stainless hlau nws tus kheej muaj qee qhov thermal conductivity, lub tshuab nqus tsev txheej, ua raws li thermal barrier, zoo heev slows tus nqi ntawm tshav kub conduction.
