Kumu Huahana

Hana ʻia ka graphite flake kiʻekiʻe -thermal-conductivity mai ka graphite flake maoli ma o ka hoʻomaʻemaʻe ʻana a me ka hoʻoheheʻe ʻia ʻana (a i ʻole ka hoʻoheheʻe ʻia ʻana o ka pauka -). Loaʻa i kāna ʻano papa ʻano ʻokoʻa i kona waiwai kumu. Hāʻawi ʻo ia i ka "wela wela kiʻekiʻe, haʻahaʻa haʻahaʻa haʻahaʻa haʻahaʻa, multi{7}}scenario adaptable" solution thermal, hoʻoponopono i nā mea metala '(copper, aluminika) kiʻekiʻe ke kumu kūʻai/density pilikia a me ka lanakila ʻana i ka nawaliwali wela o nā metala ʻole, hoʻopiha pono i nā hakahaka mākeke.

Nā hiʻohiʻona koʻikoʻi (Kūpono i ka Thermal Conductivity -Nā Waiwai Pili)

① Anisotropic High Thermal Conductivity

ʻO kona ʻano papa hana (e like me "stacked thermal conductive sheets") ka mea i ʻoi aku ka kiʻekiʻe ma ka -plane thermal conductivity ma mua o ke{1}}plane performance. I loko o kēlā me kēia papa, High Thermal Conductivity Flake Graphite wikiwiki-e kaena ana i ka hana wela he 20-50 manawa ma mua o ka resins kahiko. I kēia manawa, hiki ke hoʻolikelike ʻia ka conductivity thermal cross-plane e like me ka mea e pono ai, i mea kūpono no nā hiʻohiʻona "directional heat dissipation" (e laʻa, ka hoʻomalu wela kūloko o nā mea uila).

② Kūʻai Thermal Haʻahaʻa & Paʻa Kiʻekiʻe

Hō'ike 'o ia i ka -maha ha'aha'a ha'aha'a loa ( I lalo a i 'ole like me 0.15 K·m²/W) i ka wā o ka ho'oili wela. Eia kekahi, i loko o ke ana wela o -200 degere a 600 degere, ʻaneʻane loli ʻole kona conductivity wela, me ka hehee ʻole a me ka palaho. Hāʻawi kēia paʻa i ka hana hilinaʻi ma nā kaiapuni kiʻekiʻe kiʻekiʻe a me ka wela haʻahaʻa.

③ Māmā a maʻalahi e hana

Me ka mānoanoa o 2.2-2.3 g/cm³ wale nō (ma kahi o 1/4 o ke keleawe a me 2/3 o ka alumini), hiki ke hana ʻia i nā pauka, nā kiʻiʻoniʻoni lahilahi, nā gaskets, a me nā ʻano ʻē aʻe. Hoʻopili pololei ia i nā ʻaoʻao like ʻole (e like me nā ʻāpana uila a me nā pā pākaukau) a kākoʻo i ka hoʻonohonoho maʻalahi.

④ Maʻemaʻe kiʻekiʻe a me nā haumia haʻahaʻa

ʻOi aku ka maʻemaʻe o ka graphite ma mua o 95% a i ʻole like me 95% (me nā māka maʻemaʻe kiʻekiʻe a hiki i 99.95%), a ʻoi aku ka liʻiliʻi o ka lehu ma mua o 0.5%. ʻO ka loaʻa ʻole o nā mea haumia metala e hoʻopau i ke keakea i ke ala hoʻoheheʻe wela, e pale ana i ka piʻi ʻana o ke kūpaʻa wela kūloko a i ʻole ka ʻino electrochemical-e hoʻomāhuahua ai.

ʻO nā uhi hoʻoheheʻe wela no nā Tab Batri: Hoʻokumu ʻia ka pauda graphite flake i mau uhi wela -conductive, i hoʻohana ʻia i nā ʻili papa. Hoʻomaikaʻi kēia i ka hoʻokele electron a me ka hoʻololi ʻana i ka wela, e hōʻemi ana i ka piʻi ʻana o ka pākaukau i ka wā o ka hoʻouka ʻana a me ka hoʻokuʻu ʻana (emi a like paha me 5 degere).

③ Lako Hana Hana: Kiekie -Menahana Hoʻoheheʻe/Insulation

ʻO nā ʻāpana hoʻoheheʻe wela no nā lining kapuahi metallurgical: Hoʻokumu ʻia ka graphite flake maʻemaʻe kiʻekiʻe i mau pōhaku lepo a waiho ʻia ma nā paia o loko o nā kapuahi metala. Hoʻoikaika ia i ka hoʻoili wela i loko o ka umu, e loaʻa ana i ka hāʻawi like ʻana o ka mahana (e hōʻemi ana i nā ʻokoʻa wela kūloko ma 10-15 degere).

Paipu Paipu: Hoʻohui ʻia ka pauka graphite flake me nā resins insulating e hana i nā mea hoʻopili paipu. Hoʻemi ia i ka nalo wela ma nā haʻahaʻa haʻahaʻa (insulation) a hoʻomaʻamaʻa i ka lawe ʻana i ka wela ma nā wela kiʻekiʻe (heat tracing), kūpono i nā pipeline kemika a me ka wela.

④ ʻOihana Kaʻa: Hoʻoluʻu Component

Nā Pānaʻi wela no nā kaʻa kaʻa ikaika hou: Hoʻokomo ʻia nā pad flake graphite ma waena o nā hale kaʻa a me nā ʻōnaehana hoʻomaha. Hoʻopau koke lākou i ka wela i hana ʻia e ka hana kaʻa, hoʻomaikaʻi i ka pono kaʻa a hoʻemi i ka hoʻohana ʻana i ka ikehu e 5% -8%.

Ma ka -Ka Papa Hoʻoiho (OBC).: Hoʻopili ʻia nā kiʻi ʻoniʻoni flake graphite i nā ʻili o nā ʻāpana OBC i loko, e hoʻoholo ana i nā pilikia wela kiʻekiʻe i ka wā o ka hoʻopaʻa wikiwiki ʻana a me ka hoʻopaʻa ʻana i ka palekana.

Hōʻuluʻulu manaʻo

Hoʻohana kēia kiʻekiʻe-thermal-conductivity flake graphite i kona ʻano anisotropic, ʻoi aku ka maikaʻi o ka hoʻoheheʻe ʻana i ka wela, ka hoʻolālā māmā, a me ke kūpaʻa kūʻokoʻa. Hoʻohana ia ma ke ʻano he mea hoʻokele wela koʻikoʻi ma waena o ka uila, ka ikehu hou, ka ʻenehana, a me nā ʻāpana automotive, e kamaʻilio ana i nā wahi ʻeha koʻikoʻi e like me ka wela ʻole o ka wela, nā ʻāpana kaumaha, a me ka instability kaiapuni.
