Iyini i-thermal conductivity ye-foam yethusi?

Igwebu lethusiinto enezimbobo kakhulu ezakhiwe ngemicu yethusi exhumene, okuholela kunethiwekhi enezinhlangothi ezintathu ezihlinzeka ngendawo enkulu yokudlulisa ukushisa. Lo mklamo omusha uvumela ukuthintana okukhulu nendawo ezungezile, okuvumela ukuguquguquka kwe-thermal okuphumelelayo kanye nokulahlwa kokushisa okuthuthukisiwe. Ngobuqotho bayo obukhethekile besakhiwo kanye nokushisa okuphezulu kwe-thermal, i-foam yethusi iyisixazululo esiphelele sokubhekana nezinselele zokulawula ukushisa ezimbonini ezihlukahlukene.

Enye yezinto ezibaluleke kakhulu ekukhetheni aizinto zokuphatha ezishisayoi-thermal conductivity yayo. Nge-foam yethusi, ukuqhutshwa kwe-thermal kuphakeme kakhulu kunezinto zethusi zendabuko. Isakhiwo esiyingqayizivele se-foam yethusi sivumela ukudluliswa kokushisa okungcono, okwenza kube ukukhetha okuhle kakhulu kwezinhlelo zokusebenza ezidinga ukuphathwa okushisayo okuphakeme. I-thermal conductivity yegwebu lethusi isukela ku-300 W/m·K ukuya ku-400 W/m·K, ihlinzeka ngamakhono akhethekile okukhipha ukushisa ngisho nezidingo zokulawula ukushisa okudinga kakhulu.

I-foam yethusihigh conductivity ezishisayo kwenza kube ukukhetha okuhle kakhulu ezihlukahlukene izicelo, kuhlanganiseamasinki okushisa, izinto zokusebenzelana ezishisayo, nokupholisa idivayisi ye-elekthronikhi. Ngokusebenzisa igwebu lethusi, abakhiqizi bangathuthukisa ukusebenza kwemikhiqizo yabo futhi bathuthukise ukusebenza kahle kwamandla. Kungakhathaliseki ukuthi ikwezimoto, i-aerospace, noma i-electronics, i-copper foam inikeza isisombululo esiguquguqukayo nesisebenzayo sokuphatha ukushisa nokuthuthukisa ukusebenza kukonke.

Ngokufigqiwe,igwebu lethusikuyinto eyisisekelo enikezela nge-thermal conductivity engenakuqhathaniswa, okwenza kube ukukhetha okuhle kwezinhlelo zokusebenza eziningi zokuphatha ukushisa. Ngesakhiwo sayo se-porous esiyingqayizivele namandla akhethekile okudlulisa ukushisa, igwebu lethusi ikusasa lobuchwepheshe bokuphatha okushisayo. Kungakhathaliseki ukuthi ubheke ukuthuthukisa ukusebenza kwemishini kagesi noma uthuthukise ukusebenza kahle kwezishintshi zokushisa, igwebu lethusi yisixazululo obulokhu usifuna. Faka imali esikhathini esizayo sokuphatha okushisayo nge-foam yethusi.
