Phase Change Materials yog dab tsi
Phase Change Materials (PCMs) yog cov khoom uas tuaj yeem khaws thiab tso tawm ntau lub zog thermal thaum lawv hloov ntawm ib theem mus rau lwm qhov, xws li los ntawm cov khoom mus rau cov kua lossis kua rau roj.Cov ntaub ntawv no yog siv rau thermal zog cia thiab tswj nyob rau hauv ntau yam kev siv, xws li nyob rau hauv lub tsev rwb thaiv tsev, tub yees, thiab thermal tswj nyob rau hauv cov khaub ncaws.
Thaum lub PCM nqus cua sov, nws dhau los ua ib qho kev hloov pauv, xws li melting, thiab khaws cov thermal zog li latent cua sov.Thaum qhov ntsuas kub ib puag ncig txo qis, PCM solidifies thiab tso tawm cov cua sov uas khaws cia.Cov cuab yeej no tso cai rau PCMs kom tswj tau qhov kub thiab txias thiab tswj kev nplij siab hauv ntau qhov chaw.
PCMs muaj nyob rau hauv ntau hom, nrog rau cov organic, inorganic, thiab eutectic cov ntaub ntawv, txhua tus muaj sib txawv melting thiab khov cov ntsiab lus kom haum rau tej kev siv.Lawv tau siv ntau ntxiv hauv cov thev naus laus zis thiab kev siv hluav taws xob kom txo tau lub zog siv thiab txhim kho kev ua haujlwm thermal.
Advantge ntawm Pcm cov ntaub ntawv
Phase Change Materials (PCMs) muaj ntau yam zoo hauv ntau daim ntawv thov:
1. Thermal zog cia: PCMs tuaj yeem khaws thiab tso tawm ntau lub zog thermal thaum lub sij hawm hloov pauv, tso cai rau kev tswj hwm thermal thiab khaws cia zoo.
2. Kev tswj qhov kub thiab txias: PCMs tuaj yeem pab tswj qhov kub thiab txias hauv cov tsev, tsheb, thiab cov khoom siv hluav taws xob, tswj qhov chaw zoo thiab ruaj khov.
3. Kev siv hluav taws xob zoo: Los ntawm kev khaws cia thiab tso tawm thermal zog, PCMs tuaj yeem txo qhov xav tau ntawm cov cua sov los yog txias, ua rau kev txuag hluav taws xob thiab txhim kho kev ua haujlwm.
4. Qhov chaw-txuag: Piv rau cov txheej txheem thermal khaws cia, PCMs tuaj yeem muab cov khoom siv hluav taws xob ntau dua, tso cai rau cov qauv tsim kom haum thiab qhov chaw zoo.
5. Cov txiaj ntsig ntawm ib puag ncig: Kev siv PCMs tuaj yeem pab txo qis cov pa hluav taws xob hauv tsev cog khoom thiab kev siv hluav taws xob tag nrho, ua rau lawv muaj kev xaiv zoo rau kev tswj xyuas thermal.
6. Flexibility: PCMs muaj nyob rau hauv ntau hom thiab tuaj yeem ua raws li qhov kub thiab txias thiab kev siv, muab kev yooj yim hauv kev tsim thiab kev siv.
Zuag qhia tag nrho, PCMs muaj ntau yam txiaj ntsig uas ua rau lawv muaj txiaj ntsig zoo rau kev khaws cia hluav taws xob thermal thiab kev tswj hwm hauv ntau qhov kev lag luam.
Qhov txawv ntawm dab tsiGel Ice PackThiabPcm Lub Freezer Pob?
Gel packs thiab Phase Change Materials (PCMs) yog ob qho tib si siv rau thermal zog cia thiab tswj, tab sis lawv muaj qee qhov sib txawv tseem ceeb:
1. Cov khoom xyaw: Cov gel ntim feem ntau muaj cov khoom zoo li gel, feem ntau yog dej-raws li, uas khov rau hauv lub xeev khov thaum txias.PCMs, ntawm qhov tod tes, yog cov ntaub ntawv uas tau hloov mus rau theem, xws li los ntawm cov khoom mus rau cov kua, khaws cia thiab tso tawm thermal zog.
2. Qhov kub thiab txias: Gel packs feem ntau yog tsim los tswj qhov kub thiab txias ntawm cov dej khov, feem ntau yog 0 ° C (32 ° F).PCMs, txawm li cas los xij, tuaj yeem tsim kho kom muaj qhov hloov pauv kub tshwj xeeb, tso cai rau ntau yam kev tswj qhov kub thiab txias, txij li qhov ntsuas kub qis mus rau qhov ntau dua.
3. Reusability: Gel packs feem ntau siv ib zaug los yog muaj kev txwv tsis pub siv, vim lawv tuaj yeem degrade thaum lub sij hawm los yog rov siv dua.PCMs, nyob ntawm cov khoom siv tshwj xeeb, tuaj yeem tsim rau ntau lub sijhawm hloov pauv, ua rau lawv ruaj khov thiab siv tau ntev dua.
4. Lub zog ceev: PCMs feem ntau muaj lub zog khaws cia ntau dua piv rau cov gel packs, txhais tau tias lawv tuaj yeem khaws cov thermal zog ntau dua ib chav tsev ntim lossis qhov hnyav.
5. Daim ntawv thov: Gel packs feem ntau yog siv rau lub sij hawm luv luv txias los yog khov daim ntaub ntawv, xws li nyob rau hauv txias txias los yog rau kev kho mob lub hom phiaj.PCMs yog siv nyob rau hauv ntau yam kev siv, nrog rau lub tsev rwb thaiv tsev, thermal tswj nyob rau hauv cov khaub ncaws, thiab kub tswj shipping thiab cia.
Hauv cov ntsiab lus, thaum ob qho tib si gel pob thiab cov PCMs tau siv rau kev tswj thermal, pcms muaj ib qho dav dav, thiab cov ntawv thov ntau dua piv rau cov pob gel.
