Yiyiphi intsimbi echitha ubushushu ngokukhawuleza?

I-foam yobhedu iyaziwa ngokuba yi-thermal conductivity egqwesileyo. Ubhedu lune-thermal conductivity emalunga ne-398 W/m·K, iyenza ibe yenye yezona zikhondakthi zobushushu bazo zonke iintsimbi. Oku kwenzaugwebu lobheduilungele izicelo ezifuna ukutshatyalaliswa kobushushu ngokukhawuleza, njengabatshintshi bobushushu, iinkqubo zokupholisa ngombane kunye nezisombululo zolawulo lobushushu. Ulwakhiwo olunemingxuma oluphezulu lwegwebu lobhedu lukwabonelela ngommandla omkhulu wokufudumeza ubushushu, ukongeza ngakumbi amandla alo okuphelisa ubushushu.

Kwelinye icala,ugwebu aluminiyamkwakhona ineempawu ezichukumisayo zokuqhuba i-thermal. I-thermal conductivity ye-aluminiyam imalunga ne-200 W/m·K. Ayiyiyo i-thermal conductive njengobhedu, kodwa isengumqhubi osebenzayo we-thermal. Ugwebu lweAluminiyam lukhaphukhaphu kwaye lulungele ukusetyenziswa kobunzima obufana ne-aerospace kunye nemizi-mveliso yeemoto. Ukunganyangeki kwayo kwi-corrosion kunye nokuqina kwayo kuyenza ibe lukhetho oludumileyo lokupholisa kwiindawo ezirhabaxa.

Ngokuthelekisa i-thermal conductivity ye-foam yobhedu kunye ne-aluminium foam, kunokubonwa ngokucacileyo ukuba i-foam yobhedu inomgangatho ophezulu we-thermal conductivity, eyenza isebenze ngakumbiukutshatyalaliswa kobushushu. Nangona kunjalo, kukho ezinye izinto ekufuneka ziqwalaselwe xa ukhetha phakathi kwezixhobo ezimbini zokusetyenziswa kwe-thermal. Ngokomzekelo, iimfuno ezicacileyo zesicelo, ezifana nokunciphisa ubunzima, ukuxhathisa ukubola, kunye neendleko, nazo zinefuthe ekukhethweni kwe-foam yesinyithi.

Ukongeza kwi-thermal conductivity, ukuyila kunye nenkqubo yokuvelisa i-foam yensimbi nayo idlala indima ebalulekileyo ekukwazini ukukhupha ukushisa. I-porosity, ubungakanani bepore, kunye nesakhiwo esipheleleyo segwebu sinokuchaphazela kakhulu ukusebenza kobushushu. Zombinii-foam yobhedu kunye ne-aluminium foaminokuveliswa nge-porosity eyahlukeneyo kunye nobungakanani bepore ukwenza ngcono ukusebenza kwabo kwe-thermal kwizicelo ezithile.

Ukongeza, ukuqhubela phambili kwisayensi yezixhobo kunye nobunjineli kukhokelele ekuphuhliseni amagwebu esinyithi adibeneyo adibanisa izibonelelo zobhedu kunye ne-aluminium. Ezi foams ezixubileyo zinika ibhalansi phakathi kwe-thermal conductivity, ubunzima kunye neendleko, okwenza ukuba zifaneleke kwiintlobo ezahlukeneyo zokupholisa.

Isishwankathelo, ngelixa i-foam yobhedu ine-conductivity ephezulu ye-thermal kwaye ikhupha ukushisa ngokufanelekileyo ngakumbi kune-foam ye-aluminium, ukhetho phakathi kwezinto ezimbini ekugqibeleni luxhomekeke kwiimfuno ezithile kunye nemida yesicelo. Zombinii-foam yobhedu kunye ne-aluminium foamzineepropathi zazo ezizodwa kunye neengenelo, kwaye njengoko inzululwazi yemathiriyeli iqhubela phambili, amashishini ngoku anokhetho oluninzi olufumanekayo lokuphucula ukutshatyalaliswa kobushushu.
