Heat mea poho wai:
Pahu wela pili ka mea i ka mea kiko?ī i ho?ohana ?ia e ka poho wela. He ?oko?a ka conductivity pākana o kēlā me kēia mea, ho?onohonoho ?ia mai ke ki?eki?e a i ka ha?aha?a e like me ka conductivity mehana, kēlā me kēia kālā, keleawe, aluminika, kila.
?O ka hopena ?oi loa e ho?ohana i ke keleawe. ?Oiai ?oi aku ka li?ili?i o ka aluminika, maopopo le?a ?a?ole wela e like me ke keleawe (?o ia wale nō ma kahi o 50 pākēneka ?oi aku ka maika?i).
?O nā mea ma?amau o ka wela wela ke keleawe a me ke kinikini aluminika, nā mea ?elua a me nā mea maika?i ?ole.
He maika?i maika?i ka hana keleawe, akā pipi?i ke kumu kū?ai, ?oi aku ka ki?eki?e o ka hana, nui loa ke kaumaha (?oi aku ka nui o nā radiator keleawe ma mua o ka palena o ke kaupaona o ka CPU), li?ili?i ka wela, a ma?alahi ho?i e ho?ohehe?e ?ia.
Ma?ema?e loa ka aluminika ma?ema?e, ?a?ole hiki ke ho?ohana pololei ?ia, ho?ohana ?ia e hā?awi i ka pa?akikī o ke kinikini aluminika, ?emi ke kinikini alumini, kaupaona māmā, akā ?oi aku ka maika?i o ka conductivity wela ma mua o ke keleawe.
Ka hana a me ka ?enehana ?ana o nā poho wela:
Ho?oma?ama?a wale ?ia ka ?enehana extrusion alumini i nā ingots alumini ma kahi o 520 ~ 540 ℃ i ke ana wela ki?eki?e, e kahe ka wai o ke alumini i loko o ka extrove groove e make ma lalo o ke kaomi ki?eki?e, e ho?omoe i ka wela i loko o ka embryo, a laila ?oki a ?a?ai i ka poho wela. embryo mua a hana i ka pulu wela i ?ike pinepine ?ia.
?O ka ma?alahi o ka ho?okō ?ana a me nā kumukū?ai ha?aha?a ha?aha?a o ka extrusion alumini i ho?ohana ākea ?ia ia i ka hopena ha?aha?a o ka mākeke i nā makahiki i hala.
?O ka mea i ho?ohana pinepine ?ia me ka alumini-extrusion AA6063 he conductivity wela maika?i (e pili ana i 160 ~ 180 W / mK) a me ka hana.
Pulu wela wela alumini
?O ka ho?omehana wela alumini maoli ka mea ma?amau o ka radiator mua, he ma?alahi kāna ka?ina hana, he kumu kū?ai ha?aha?a, he mau wahi wela wela nāwewe piha i kahi mahele nui o ka mākeke.
I mea e ho?onui ai i ka wela dissipation ?āpana o nā fin, ?o ka extrusion alumini ke ?ano hana i ho?ohana pinepine ?ia no nā radiator alumini ma?ema?e, a ?o nā papa kuhikuhi nui no ka loiloi ?ana i kahi ho?omehana wela aluminika ma?ema?e ka mānoanoa o ka base radiator a me ka lakio Pin-Fin.
?O Pin e pili ana i ke ki?eki?e o ka Fin o ka radiator, ?oiai ?o Fin e pili ana i ka mamao ma waena o nā ?elua e pili ana. Ho?oka?awale ?ia ka lākiahi Pin-fin e Fin e ke ki?eki?e o Pin (?a?ole me ka mānoanoa o ke kumu). ?O ka lakio Pin-Fin ?oi aku ka nui o ka nui o ka wela dissipation area o ka radiator, ?o ia ho?i ka holomua o ka ?enehana extrusion aluminium.
Ho?oku?u ?ia ?o Aluminium?poho wela?mea ho?olako:
Ho?okumu nā heatsink extrusions ?oihana i nā ?oihana ?oihana, maika?i loa ka maika?i o ka huahana, pono pono ke hilina?i i ka wela, ?olu?olu e kū?ai; Weihua - mea hana heatsink alumini extruded
