Passive coolers yog cov khoom cua txias uas tsis tas yuav muaj hluav taws xob los tsav. Nws ua tiav cov cua txias thiab kev txuag hluav taws xob los ntawm kev tsim ntse thiab cov khoom siv siab heev.
Cov ntaub ntawv thiab cov qauv
Lub hauv paus ntawm passive tub yees nyob rau hauv nws cov khoom thiab cov qauv tsim. Nws feem ntau yog ua los ntawmhigh-efficiency thermal rwb thaiv tsev cov ntaub ntawv, xws li polyurethane ua npuas ncauj (PU), polystyrene ua npuas ncauj (EPS), thiab lwm yam. Cov ntaub ntawv no muaj cov thermal conductivity tsawg thiab tuaj yeem thaiv cov cua sov sab nraud kom nkag mus rau sab hauv lub thawv.
Polyurethane ua npuas ncauj (PU):
Cov khoom siv no muaj kev ua haujlwm zoo thermal rwb thaiv tsev thiab lub zog muaj zog thiab yog siv dav hauv phab ntsa sab hauv thiab sab nrauv ntawm lub tub yees.
Polystyrene ua npuas ncauj (EPS):
EPS yog ib qho khoom siv thermal rwb thaiv tsev. Cov khoom siv no yog lub teeb hauv qhov hnyav, yooj yim rau nqa thiab khiav lag luam, thiab tuaj yeem muab cov rwb thaiv tsev zoo.
Thaum tshav kub kub pauv txoj cai
Cov nyhuv txias ntawm lub tub yees passive feem ntau yog nyob ntawm lub hauv paus ntsiab lus ntawm kev sib pauv cua sov. Cov dej khov nab kuab lossis cov dej txias hauv lub thawv nqus cov cua sov ib puag ncig kom txo qhov kub ntawm sab hauv. Cov khoom ua kom txias muaj xws li cov hnab ntim dej khov, lub thawv dej khov, cov dej khov qhuav, thiab lwm yam, uas tuaj yeem khaws lub thawv ntawm qhov kub tsis tshua muaj sijhawm ntev.
Ice hnab / ice boxes:
Cov hnab ntim dej khov thiab cov thawv dej khov nqus cov cua sov ntau thaum lub sij hawm melting, ua kom cov khoom hauv lub thawv txias.
Dej khov qhuav:
Cov dej khov qhuav nqus cua sov los ntawm sublimation (khoom ncaj qha rau hauv cov pa), uas tuaj yeem muab cov nyhuv txias dua. Txawm li cas los xij, cov dej khov qhuav tso tawm cov pa roj carbon dioxide, yog li nws yuav tsum tau siv nrog ceev faj thiab ua raws li cov lus qhia kev nyab xeeb.
Sealing tsim
Sealing tsim yog ib feem tseem ceeb ntawm passive tub yees. Qhov zoo tshaj plaws sealing strips thiab lub kaw lus kaw tau zoo tuaj yeem tiv thaiv cov huab cua sab nraud los ntawm kev nkag mus thiab tswj qhov kub thiab txias hauv lub thawv. Lub sealing strips feem ntau yog ua los ntawm cov khoom siv silicone, uas muaj qhov zoo elasticity thiab durability thiab muaj peev xwm tswj tau cov nyhuv sealing rau lub sijhawm ntev.
Thaum tshav kub kub reflection thiab hluav taws xob
Ntxiv nrog rau cov khoom siv thiab cov qauv, cov tub yees passive kuj tseem siv cov ntsiab lus ntawm kev xav txog cua sov thiab hluav taws xob los txhim kho qhov txias txias. Cov phab ntsa sab hauv thiab lub plhaub sab nrauv feem ntau yog coated nrog cov txheej txheem uas tuaj yeem cuam tshuam cov hluav taws xob sab nraud thiab txo qhov nqus cua sov ntawm lub thawv. Nyob rau tib lub sijhawm, cov txheej txheej sab hauv lub thawv kuj tseem tuaj yeem cuam tshuam cov hluav taws xob txias tso tawm los ntawm lub tshuab ua kom txias, ua rau cov nyhuv txias dua.
Los ntawm cov ntsiab cai saum toj no,Lub tub yees tuaj yeem ua tiav cov txiaj ntsig zoo txias yam tsis muaj hluav taws xob, uas yog ib qho kev txuag hluav taws xob thiab ib puag ncig tus phooj ywg tub yees artifact.
