Dab tsi yog cov yeeb nkab pov tseg thaum tshav kub kub rov qab? Dab tsi yog cov txiaj ntsig ntawm kev kho cua sov?

Thaum tshav kub kub yeeb nkab yog ib qho tshiab hloov hluav taws xob uas muaj thermal conductivity siab heev. Cov kav dej kub tau pib hauv Tebchaws Meskas thaum xyoo 1960s. Nyob rau hauv 1967, stainless hlau dej kub yeeb nkab tau ntse xa mus rau lub ntiaj teb satellite orbit thawj zaug. Txoj kev xav ntawm kev tswj cov cua sov tau txais txiaj ntsig zoo los ntawm cov kws tshawb fawb los ntawm ntau lub teb chaws thiab ntau qhov kev tshawb fawb tau ua tiav, uas ua rau muaj kev loj hlob sai ntawm cov yeeb nkab cua sov tshuab. Thaum tshav kub kub yeeb nkab tshuab pib siv tsuas yog nyob rau hauv aerospace teb. Tuam Tshoj pib tshawb fawb cov kav dej kub hauv xyoo 1970 thiab tau tsim thiab siv txij li xyoo 1980s.

Txoj haujlwm ua haujlwm:

Cov yeeb nkab cua sov yog tsim los ntawm cov hlau, tooj liab, thiab txhuas cov kav dej uas muaj cov khoom siv hluav taws xob thermal, uas raug kaw tom qab raug tshem tawm mus rau ib qho twg. Qhov nruab nrab ua haujlwm hauv cov yeeb nkab yog qhov sib xyaw ntawm ntau yam sib xyaw, uas muaj cov thermal ua haujlwm txawv txawv thiab rhiab heev. Nws absorbs cua sov thaum nws ntsib cua sov thiab tso tawm thaum nws ntsib txias. Hom dej ua haujlwm superconducting no yog qhib rau ntawm qhov kub thiab txias thiab hloov cov cua sov hauv daim ntawv ntawm molecular oscillation theem hloov. Nws muaj zog thermal conductivity ua rau nws cov thermal conductivity txog 10000 npaug ntawm cov hlau zoo tib yam, thiab qhov kub ntawm qhov conduction tsis lwj thiab tuaj yeem xa mus rau qhov ceev ceev heev.

Nta:

1. Super thermal conductivity: ceev thermal conductivity, siab zog, high efficiency, thiab txhim khu kev qha thermal conductivity mus txog qhov ceev ntawm lub suab.

2. Zoo isotherm: Zoo isotherm ua rau cov yeeb nkab cua sov hloov cov cua kub loj thiab txo cov cua sov hloov ntawm qhov sib txawv me me.

3. Heat flux variability: Cov kav dej kub tuaj yeem hloov pauv qhov cua sov ntawm cov evaporation thiab txias seem, uas yog, cov khoom siv hluav taws xob me me thiab cov khoom siv hluav taws xob nrog rau qhov chaw txias dua, lossis cov kav dej kub tuaj yeem nkag nrog thaj tsam loj dua qhov kub thiab txias. tso zis nrog rau qhov chaw txias me me.

4. Kev nyab xeeb thiab kev ntseeg tau: Tsis muaj kev kub ntxhov hauv cov kav dej. Tom qab vaporization ntawm cov kua dej ua haujlwm, lub siab sab hauv ntawm cov yeeb nkab kub tsis hloov nrog qhov kub thiab txias.

5. Kev hloov pauv ib puag ncig: Tsis txwv los ntawm ib puag ncig, cov kav dej kub tuaj yeem tsim tau nyias raws li qhov xav tau ntawm ib puag ncig.

6. Kev siv dav hauv cheeb tsam: Cov kav dej kub superconducting muaj kev hloov pauv ntau dua hauv cov duab thiab ntau yam kev siv, tuaj yeem hloov mus rau ntau qhov chaw ua haujlwm hnyav.

Cov yam ntxwv ntawm kev ua haujlwm ntawm cov yeeb nkab cua sov pov tseg thaum tshav kub kub rov qab:

1. Cov yeeb nkab hluav taws xob pov tseg thaum tshav kub kub rov qab muaj kev hloov pauv hluav taws xob siab thiab cov txiaj ntsig tseem ceeb ntawm kev txuag hluav taws xob.

2. Kev txhim kho yooj yim thiab kev teeb tsa: Cov qauv tsim thiab kev teeb tsa tau yooj yim heev, haum rau ntau lub sijhawm nyuaj.

3. Lub neej ua haujlwm ntev: Lub neej kev pabcuam yog ntau tshaj 15 xyoo, thiab ib lub raj cua sov tuaj yeem muab tshem tawm thiab hloov, nrog kev saib xyuas yooj yim thiab tus nqi qis.

4. Lub sij hawm them rov qab luv luv: Feem ntau, tag nrho cov kev nqis peev tuaj yeem rov qab tau li ntawm rau lub hlis mus rau ib xyoos.
