Cov iav insulating tsis tas yuav tsum tau ua los ntawm txhuas, tab sis aluminium spacers (tshwj xeeb tshaj yog "aluminium spacers") yog tam sim no feem ntau siv thiab technologically mature xaiv nyob rau hauv kev ua lag luam.
Vim li cas aluminium spacers yog lub ntsiab tseem ceeb?
Cov ntaub ntawv txhuas tuaj yeem tuav ntau dua 90% ntawm kev ua lag luam feem ntau vim muaj cov yam ntxwv zoo li hauv qab no:
Tsis tshua muaj noo noo permeability thiab huab cua permeability
Qhov no yog qhov laj thawj tseem ceeb tshaj plaws. Sab hauv ntawminsulating iavyog ntim nrog cua qhuav los yog inert gas (xws li argon) los muab rwb thaiv tsev thiab tiv thaiv condensation. Aluminium nws tus kheej muaj cov qauv ntom thiab tuaj yeem tiv thaiv dej vapor los ntawm sab nraud los ntawm kev nkag mus rau sab hauv ntawm cov iav insulating. Thaum cov roj sab hauv tau damp, iav yuav condense thiab pos huab ntawm qhov kub thiab txias, cuam tshuam rau qhov pom thiab pom, thiab tib lub sijhawm, nws cov rwb thaiv tsev ua haujlwm yuav poob qis heev.
Nws muaj qhov zoo ntawm qhov ruaj khov thiab siab zog
Aluminium muaj qhov zoo rigidity thiab tsis yooj yim rau khoov lossis deformation thaum ua, kev thauj mus los thiab kev teeb tsa, uas tuaj yeem ua kom muaj qhov sib txawv ntawm ob (lossis peb) daim iav insulating. Qhov kab noj hniav ruaj khov no yog tus yuam sij rau kev ua kom muaj kev sib raug zoo thiab ua kom muaj cua sov zoo ib yam thiab kev ua haujlwm ntawm lub suab rwb thaiv tsev.
Lub teeb hauv qhov hnyav
Piv nrog rau lwm cov hlau, aluminium muaj qhov ntom ntom. Cov spacers tsim los ntawm nws yuav tsis ntxiv qhov hnyav hnyav rau cov khoom siv iav insulating, uas yooj yim rau kev teeb tsa thiab txo cov load ntawm lub tsev.
Yooj yim rau txheej txheem
Cov ntaub ntawv txhuas tuaj yeem khoov tau yooj yim thiab txiav los ua ntau yam duab ntawm cov iav insulating, suav nrog square thiab arc -zoo li tus, kom ua tau raws li cov qauv tsim qauv sib txawv.
Corrosion kuj
Aluminium alloys siv rau spacers feem ntau yog saum npoo - kho (xws li anodizing), uas muaj corrosion kuj zoo thiab tuaj yeem hloov mus rau ntau yam kev nyab xeeb, ua kom muaj kev ntseeg siab ntawm kev siv sijhawm ntev -.
Lwm cov ntaub ntawv ntawm spacers thiab lawv qhov zoo thiab qhov tsis zoo
Txawm hais tias txhuas yog lub hauv paus, hauv kev nrhiav kev ua haujlwm siab dua, kuj tseem muaj cov khoom siv ua los ntawm lwm cov ntaub ntawv ntawm kev ua lag luam:
1. Sov -ntug spacer bar - Tus neeg sib tw tseem ceeb
Lub tshuab "sov ntug" yog tsim los daws qhov teeb meem loj ntawm aluminium spacers: lawv cov thermal conductivity siab. Aluminium yog ib tug zoo conductor ntawm tshav kub. Yog li ntawd, cov tsoos aluminium spacers tsim ib qho "txias choj", ua rau lub tshav kub ntawm ntug ntawm insulating iav kom dissipate sai dua. Nyob rau hauv lub caij ntuj no, condensation yog yuav tsim nyob rau ntawm ntug ntawm lub khob.
Qhov sov-ntug spacer bar siv cov khoom siv nrog cov thermal conductivity qis dua los hloov cov txhuas, yog li txhim kho cov rwb thaiv tsev ntawm tag nrho lub qhov rais. Common sov-ntug spacers suav nrog:
Stainless hlau spacer tuav: Lawv muaj lub zog siab thiab qis thermal conductivity tshaj txhuas, ua rau lawv xaiv zoo heev ntawm kev ua tau zoo, tab sis lawv kuj kim heev.
Composite khoom spacer bar
Swiggle Strip (wavy rubber strip): Ib qho txuas txuas txuas txuas txuas txuas nrog cov hlau thaiv txheej, nws muaj cov thermal conductivity tsawg heev thiab yog qhov sov sov - ntug tshuab.
TPS (Thermoplastic spacer): Ib qho khoom siv roj hmab feem ntau ua los ntawm cov roj hmab tshwj xeeb butyl, uas hloov mus rau hauv lub xeev yas tom qab cua sov thiab ncaj qha coated rau iav los ntawm cov khoom siv siab. Nws yuav luag tag tshem tawm "txoj choj" ntawm cov hlau, muaj kev txuag hluav taws xob zoo heev, thiab tuaj yeem ua tiav kev sib khi zoo thiab huab cua nruj.
2. Ib txwm siv tsis yog- cov khoom siv hlau (tsawg siv tam sim no)
Roj hmab-raws li/organic roj hmab spacers: Qee qhov ntxov lossis qis- cov khoom siv kawg siv lawv, tab sis lawv lub zog thiab kav ntev feem ntau tsis zoo li cov hlau spacers.
