Liquid Metal: Efficiency Heat Dissipation Technique in Space Stations
Thaum Lub Yim Hli 18, 2023, Tuam Tshoj Manned Space Engineering Office tau hais qhia luv luv ntawm daim ntawv thov thiab kev txhim kho ntawm manned space engineering hauv qhov chaw. Thawj cov kua hlau qhov chaw thermal tswj nyob rau hauv orbit test, raws li ib tug ntawm cov tsis ntev los no aerospace kev sim ua nyob rau hauv lub chaw nres tsheb, tau txais kev saib xyuas.
Cov khoom siv ua kua hlau thermal tswj kev ntsuas hauv qhov chaw thev naus laus zis sim teb tau tsim los ntawm Lub Tsev Haujlwm ntawm Physics thiab Chemistry Technology ntawm Suav Academy ntawm Kev Tshawb Fawb thiab tau nruab rau hauv qhov chaw sim ntsuas qhov chaw ntawm qhov chaw nres tsheb Mengtian sim module. Cov bismuth raws li cov hlau uas tsis tshua muaj melting point, muaj kev nyab xeeb thiab ruaj khov tshuaj lom neeg cov yam ntxwv tau siv los ua cov yam ntxwv kev tshawb fawb thiab kev sim tshuaj ntsuam xyuas ntawm ntws kub dissipation thiab theem hloov kub tswj tshuab nyob rau hauv qhov chaw microgravity ib puag ncig.
Cov hlau ua kua yog ib qho amorphous thiab flowable kua hlau, uas yog lub ntsiab lus sib sau ua ke ntawm cov hlau tsis tshua muaj melting point hlau thiab cov ntaub ntawv alloy. Nws yog kua nyob rau hauv chav tsev kub los yog qis cua sov kub thiab muaj ob qho tib si fluidity. Nws muaj zog conductivity, siab thermal conductivity, tsawg viscosity, thiab ib tug dav kua kub ntau yam.
Nrog rau kev txhim kho txuas ntxiv ntawm kev txawj ntse thev naus laus zis, thev naus laus zis kev muaj tiag virtual, thiab kev siv cov duab ua haujlwm siab, lub zog ntom ntom ntawm cov khoom siv hluav taws xob nrog cov haujlwm no txuas ntxiv mus rau cov lus teb rau engineering thermal tswj kev xav tau ntawm cov khoom siv hluav taws xob kub kub, xws li cov cua kub tsis tu ncua lossis cuam tshuam siab load cua sov. Txhawm rau kom ntseeg tau tias kev ua haujlwm ntawm cov khoom siv hluav taws xob nyob rau hauv cov xwm txheej siab, ua haujlwm tau zoo, ua tiav, thiab txhim khu kev qha tshav kub dissipation tshuab yuav tsum tau txais, Cov kua hlau kub dissipation tshuab yog ib qho kev sim ua pov thawj los teb rau qhov kev thov no, thiab xav kom ua lub luag haujlwm tseem ceeb hauv ntau qhov chaw.
