Iimpawu ezishushu ze-foam yesinyithi ziquka indawo yokunyibilika, ubushushu obuthile, i-coefficient yokwandisa i-thermal, i-thermal conductivity, i-thermal diffusivity, i-thermal radiation kunye nokumelana nokutshatyalaliswa kwe-thermal, ezinye zazo zifana nezinto ze-matrix, ngelixa ezinye zihambelana ne-porosity, i-Pore. uhlobo kunye nobukhulu pore zihlobene ngokusondeleyo.
Izinto eziphathekayo ezine-conductivity efanelekileyo ye-thermal zivame ukufunxa ubushushu ngokukhawuleza kwaye zikhuphe ukushisa ngokukhawuleza. Ukuba ezinye iinkqubo zifuna umlinganiselo omkhulu wokushisa ubushushu okanye ukutshatyalaliswa kobushushu ngexesha lokusetyenziswa, izinto eziphathekayo ezine-thermal conductivity zikhethiweyo. Ngokwenqanaba lokuqhutywa kwe-thermal yeentsimbi ezicocekileyo, isilivere, ubhedu, i-aluminiyam, i-tungsten, i-magnesium kunye nezinye izinto, ngelixa i-thermal conductivity ye-alloys imbi kakhulu. Inokubonwa ukuba i-thermal conductivity ye-copper heat sinks iyona nto ingcono kakhulu phakathi kweentsimbi zoshishino.

Ke kutheni le nto iitsinki zobushushu zenziwe nge-aluminiyam endaweni yobhedu?
Kukwayinyani ukuba ubhedu buqhuba kakuhle kakhulu ubushushu kuba bunobushushu obuphezulu kakhulu kune-aluminiyam. Kodwa amandla okutshatyalaliswa kobushushu be-radiator akuxhomekekanga kuphela kwi-thermal conductivity yezinto eziphathekayo, kodwa nakwindawo yokutshatyalaliswa kobushushu, imilo ye-radiator, kunye neemeko zokuhamba komoya.
Kungakhathaliseki ukuba mncinci kangakanani umthamo wokushisa wobhedu, umthamo wokushisa othile wobhedu kufuneka ube ngaphantsi, ubushushu bawo buphakama ngokukhawuleza, kwaye kulula ukukhupha ubushushu. Nangona kunjalo, ubuninzi bobhedu buphindwe ka-3.3 kune-aluminium. I-radiator yimveliso yobukhulu kwaye ayikwazi ukwandiswa ngokungenasiphelo. Emva koko ubunzima bobhedu bukhulu kumthamo ofanayo.
Ngaphantsi kwezinto ezininzi, iindleko ze-radiator zethusi zihlala zixabisa ngaphezu kwe-400% ngaphezu kwe-radiator ye-aluminium, kodwa ngokwexabiso, imarike ayikwazi ukwamkela ii-radiator zethusi eziphindwe kabini ixabiso.
Ngoko ngaba kukho nayiphi na into enokuthi ibe ne-thermal conductivity yobhedu, kodwa umthamo kunye nobunzima bufaniswa ne-aluminium?
Ubhedu olunegwebu lunokuba yinto entsha efanelwe ingqalelo, enezinto ezininzi ezidibeneyo kunye nezinqanyuliweyo ezisasazwa ngokulinganayo kwi-matrix yobhedu. Ubhedu olugwetyiweyo lunokuqhuba kakuhle kombane kunye ne-ductility, kwaye lunexabiso eliphantsi lokulungiselela kunye nokuqhuba kakuhle kombane.
