Heat mea poho wai:
Pahu wela pili ka mea i ka mea kikoʻī i hoʻohana ʻia e ka poho wela. He ʻokoʻa ka conductivity pākana o kēlā me kēia mea, hoʻonohonoho ʻia mai ke kiʻekiʻe a i ka haʻahaʻa e like me ka conductivity mehana, kēlā me kēia kālā, keleawe, aluminika, kila.
ʻO ka hopena ʻoi loa e hoʻohana i ke keleawe. ʻOiai ʻoi aku ka liʻiliʻi o ka aluminika, maopopo leʻa ʻaʻole wela e like me ke keleawe (ʻo ia wale nō ma kahi o 50 pākēneka ʻoi aku ka maikaʻi).
ʻO nā mea maʻamau o ka wela wela ke keleawe a me ke kinikini aluminika, nā mea ʻelua a me nā mea maikaʻi ʻole.
He maikaʻi maikaʻi ka hana keleawe, akā pipiʻi ke kumu kūʻai, ʻoi aku ka kiʻekiʻe o ka hana, nui loa ke kaumaha (ʻoi aku ka nui o nā radiator keleawe ma mua o ka palena o ke kaupaona o ka CPU), liʻiliʻi ka wela, a maʻalahi hoʻi e hoʻoheheʻe ʻia.
Maʻemaʻe loa ka aluminika maʻemaʻe, ʻaʻole hiki ke hoʻohana pololei ʻia, hoʻohana ʻia e hāʻawi i ka paʻakikī o ke kinikini aluminika, ʻemi ke kinikini alumini, kaupaona māmā, akā ʻoi aku ka maikaʻi o ka conductivity wela ma mua o ke keleawe.
Ka hana a me ka ʻenehana ʻana o nā poho wela:
Hoʻomaʻamaʻa wale ʻia ka ʻenehana extrusion alumini i nā ingots alumini ma kahi o 520 ~ 540 ℃ i ke ana wela kiʻekiʻe, e kahe ka wai o ke alumini i loko o ka extrove groove e make ma lalo o ke kaomi kiʻekiʻe, e hoʻomoe i ka wela i loko o ka embryo, a laila ʻoki a ʻaʻai i ka poho wela. embryo mua a hana i ka pulu wela i ʻike pinepine ʻia.
ʻO ka maʻalahi o ka hoʻokō ʻana a me nā kumukūʻai haʻahaʻa haʻahaʻa o ka extrusion alumini i hoʻohana ākea ʻia ia i ka hopena haʻahaʻa o ka mākeke i nā makahiki i hala.
ʻO ka mea i hoʻohana pinepine ʻia me ka alumini-extrusion AA6063 he conductivity wela maikaʻi (e pili ana i 160 ~ 180 W / mK) a me ka hana.
Pulu wela wela alumini
ʻO ka hoʻomehana wela alumini maoli ka mea maʻamau o ka radiator mua, he maʻalahi kāna kaʻina hana, he kumu kūʻai haʻahaʻa, he mau wahi wela wela nāwewe piha i kahi mahele nui o ka mākeke.
I mea e hoʻonui ai i ka wela dissipation ʻāpana o nā fin, ʻo ka extrusion alumini ke ʻano hana i hoʻohana pinepine ʻia no nā radiator alumini maʻemaʻe, a ʻo nā papa kuhikuhi nui no ka loiloi ʻana i kahi hoʻomehana wela aluminika maʻemaʻe ka mānoanoa o ka base radiator a me ka lakio Pin-Fin.
ʻO Pin e pili ana i ke kiʻekiʻe o ka Fin o ka radiator, ʻoiai ʻo Fin e pili ana i ka mamao ma waena o nā ʻelua e pili ana. Hoʻokaʻawale ʻia ka lākiahi Pin-fin e Fin e ke kiʻekiʻe o Pin (ʻaʻole me ka mānoanoa o ke kumu). ʻO ka lakio Pin-Fin ʻoi aku ka nui o ka nui o ka wela dissipation area o ka radiator, ʻo ia hoʻi ka holomua o ka ʻenehana extrusion aluminium.
Hoʻokuʻu ʻia ʻo Aluminium poho wela mea hoʻolako:
Hoʻokumu nā heatsink extrusions ʻoihana i nā ʻoihana ʻoihana, maikaʻi loa ka maikaʻi o ka huahana, pono pono ke hilinaʻi i ka wela, ʻoluʻolu e kūʻai; Weihua - mea hana heatsink alumini extruded
