Iyiphi insimbi echitha ukushisa ngokushesha?

Igwebu le-Copper liyaziwa ngokusebenza kwayo okuhle kakhulu kokushisa. I-Copper inokushintshwa okushisayo okungaba ngu-398 W/m·K, okuyenza ibe enye yamakhondatha ashisayo angcono kakhulu azo zonke izinsimbi. Lokhu kwenzaigwebu lethusiilungele izinhlelo zokusebenza ezidinga ukuchithwa kokushisa okusheshayo, njengezishintshisi zokushisa, amasistimu okupholisa ama-elekthronikhi kanye nezixazululo zokuphatha ukushisa. Isakhiwo esinezimbotshana ze-foam yethusi siphinde sinikeze indawo enkulu yokudlulisa ukushisa, ithuthukise ngokwengeziwe amandla ayo okukhipha ukushisa.

Ngokolunye uhlangothi,i-aluminium foamfuthi inezindawo ezihlaba umxhwele ze-thermal conductivity. I-thermal conductivity ye-aluminium icishe ibe ngu-200 W/m·K. Ayihambisani ne-thermal njengethusi, kodwa isengumqhubi we-thermal osebenza kahle. Igwebu le-aluminium lilula futhi lilungele ukusetshenziswa okuqaphela isisindo njengezimboni ze-aerospace nezimboni zezimoto. Ukumelana nokugqwala kwayo nokuqina nakho kuyenza ibe inketho ethandwayo yokupholisa ezindaweni ezinokhahlo.

Ngokuqhathanisa ukuqhutshwa kokushisa kwegwebu lethusi kanye ne-aluminium foam, kungabonakala ngokucacile ukuthi igwebu lethusi linomthamo ophezulu we-thermal conductivity, okwenza lisebenze kahleukuchithwa kokushisa. Kodwa-ke, kunezinye izici okufanele zicatshangelwe lapho ukhetha phakathi kwezinto ezimbili zokusetshenziswa okushisayo. Isibonelo, izidingo eziqondene nohlelo lokusebenza, njengemikhawulo yesisindo, ukumelana nokugqwala, nezindleko, nazo zinomthelela ekukhethweni kwegwebu lensimbi.

Ngaphandle kokusebenza okushisayo, inqubo yokuklama kanye nokukhiqiza igwebu lensimbi nayo idlala indima ebalulekile ekhonweni layo lokususa ukushisa. I-porosity, usayizi wembotshana, kanye nokwakheka okuphelele kwegwebu kungathinta kakhulu ukusebenza kwayo kokudlulisa ukushisa. Kokubilii-foam yethusi ne-aluminium foamingenziwa nge-porosity ehlukene nosayizi bembotshana ukuze kuthuthukiswe ukusebenza kwayo okushisayo kwezinhlelo zokusebenza ezithile.

Ukwengeza, ukuthuthuka kwesayensi yezinto zokwakha kanye nobunjiniyela kuholele ekuthuthukisweni kwamagwebu ensimbi ayingxube ahlanganisa izinzuzo zethusi ne-aluminium. Lawa magwebu e-hybrid anikeza ibhalansi phakathi kwe-thermal conductivity, isisindo kanye nezindleko, okubenza bafanelekele izinhlelo zokusebenza zokupholisa ezihlukahlukene.

Kafushane, kuyilapho igwebu lethusi linokuqhuba okushisayo okuphezulu futhi lihlakaza ukushisa ngokuphumelelayo kunegwebu le-aluminium, ukukhetha phakathi kwezinto ezimbili ekugcineni kuncike ezidingweni ezithile kanye nemikhawulo yohlelo lokusebenza. Kokubilii-foam yethusi ne-aluminium foamzinezakhiwo nezinzuzo zazo ezihlukile, futhi njengoba isayensi yezinto zokwakha iqhubeka nokuthuthuka, izimboni manje zinezinketho eziningi ezitholakalayo zokuthuthukisa ukunqanyulwa kokushisa.
