Thaum lub caij ntuj no, ntau tus neeg xav mus saib daus, saib auroras, thiab nyob hauv roob daus thiab hav zoov. Lawv thawj cov tshuaj tiv thaiv yog: Puas yog cov "qhov dav hlau" nyias yuav txias li lub cellar dej khov?
Yuav ua li cas tsawg lub mainstream spacecraft tiv taus? Ua ntej, cia peb kos ib qho kev txiav txim siab: Cov khoom siv dav hlau raug cai nyob rau hauv kev ua lag luam feem ntau tuaj yeem hloov mus rau qhov kub tsis txias xws li rho tawm 30℃mus rau rho tawm 40 degree. Qee cov khoom tsim tshwj xeeb tsim rau siab - thaj tsam qhov siab yog cim nrog qhov kev hloov pauv mus txog -40℃txog 55℃- piv txwv li, lub dav hlau los ntawm cov tuam txhab tsim khoom tsim tshwj xeeb los daws cov teeb meem tiv thaiv lub caij ntuj no hauv thaj chaw txias heev xws li Russia thiab North America; Kuj tseem muaj cov ntaub ntawv teev tseg ntawm cov khoom lag luam ua haujlwm tsis tu ncua tsis raug rau 60 hnub nyob rau hauv ib puag ncig ntawm rho tawm 35 degree. Qhov ntawd yog hais tias, los ntawm cov snowy countryside ntawm Northeast Tuam Tshoj mus rau cov nyom ntawm Inner Mongolia, los ntawm Qinghai Tibet Plateau mus rau Russia nyob rau hauv hiav txwv, spacecraft muaj peev xwm yeej 'thov' nws.
Txawm li cas los xij, nws yuav tsum tau muab sau tseg tias "muaj peev xwm tiv taus" muaj ob theem: cov qauv cabin tsis muaj teeb meem: nws tsis tawg, deform, los yog tsis muab khi rau ntawm qhov kub thiab txias, thiab nws tsis tawg nyob rau hauv hnyav daus siab; Nyob zoo nyob rau hauv lub alarm: nrog txaus rwb thaiv tsev kev ua tau zoo thiab cua txias los yog underfloor cua sov, lub sab hauv tsev kub yuav ruaj khov tshaj 20 degree. Ob yam khoom raug cai tuaj yeem ua tiav qhov no; Txawm li cas los xij, qis- nqi thiab qis- cov cabins zoo tus nqi ntawm kaum tawm txhiab yuan feem ntau tsuas yog muaj cov duab ntawm "lub dav hlau", tawm hauv huab cua, khov, thiab condensing ntawm qhov kub thiab txias li qis dua kaum degrees Celsius, muaj lub pob tsuas zoo li qhovntsej thiaj tsis mob.
Vim li cas lub dav hlau dav hlau tiv taus txias? Nws tso siab rau peb txheej ntawm kev ua haujlwm nyuaj
Lub phab ntsa ntawm lub dav hlau tsis yog ib daim ntawv hlau, tab sis "sandwich" qauv - ib txheej aluminium alloy vaj huam sib luag, nruab nrab polyurethane rwb thaiv tsev txheej, thiab ib lub vaj huam sib luag sab hauv. Cov txheej rwb thaiv tsev nyob nruab nrab muaj qhov tuab ntawm li 75mm rau cov qauv zoo tib yam thiab txog li 150mm rau siab -altitude enhanced qauv. Ib lub tsev uas muaj kev rwb thaiv tsev zoo tuaj yeem ua tiav qhov sib txawv ntawm qhov kub ntawm K tus nqi tsawg dua 0.5W / (㎡· K) - sib npaug rau hnav lub tsho tuab rau tag nrho chav.
Ntau lub dav hlau siv ob npaug - txheej txheej choj tawg aluminium, nrog cov ntaub ntawv rwb thaiv tsev "tshem tawm" nruab nrab ntawm sab hauv thiab sab nraud ntawm cov hlau ncej, tiv thaiv cua sov thiab cua txias los ntawm kev nkag. Qhov no kuj yog tib lub thev naus laus zis xws li siab - qhov rooj kawg thiab qhov rais nyob rau sab qaum teb.
Cov khoom lag luam tsis tu ncua siv 5+12A+5 lossis txawm tias 6+16A+6 hollow Low-E tempered iav, uas kaw hauv tsev sov thaum lub caij ntuj no, thaiv tshav ntuj raug rau lub caij ntuj sov, thiab tuaj yeem hloov kho rau peb txheej iav hauv qhov siab - qhov siab.
