Pehea e pili ana i ka hana hoʻoheheʻe wela?

ʻO ka hoʻoheheʻe wela welahe ʻano mea wela me nā ʻili i ʻoki ʻia mai loko mai o ka mea paʻa.ʻOi aku ka lahilahi o nā peʻa i loko o kahi pā wela skived fin i ka hoʻohālikelike ʻianā ʻano mea wela ʻē aʻe, likeextrusion wela wela.Hana ʻia nā puʻupuʻu wela kiʻekiʻe e ke kaʻina hana i kapa ʻia ʻo skiving, i hana ʻia e ka mīkini skiving precision kiʻekiʻe me ka pahi ʻoi i hoʻomalu pono ʻia, ʻoki ʻia ʻo ia i kahi ʻāpana lahilahi o ka mānoanoa kikoʻī mai kahi ʻāpana metala holoʻokoʻa (AL6063 a i ʻole copper C1100), a laila kūlou. ʻO ka ʻāpana ʻāpana metala ma ke poʻo e hoʻokumu i ka ʻili wela.Hāʻawi kēia ʻano wela wela i nā pōmaikaʻi e like me ka pale ʻana i ka wela liʻiliʻi, nā ala hoʻololi wela pōkole, a me ka nui paʻa.Ma lalo iho nei nā wehewehe kikoʻī o ka hana ʻana o nā mea wela skived fin mai nā hiʻohiʻona he nui.

1.Thermal Resistance: Ho'ākāka 'ia ke kū'ē wela e like me ka like'ole o ka wela ma waena o ke kumu wela a me ke kaiapuni ambient, i māhele'ia e ka wela wela, ai'ole ka nui o ka ho'oili wela, ma o ka wela wela:

Rth = (Tsource - Tambient) / Q

kahi ʻo Rth = pale wela (ma nā degere Celsius no ka Watt), Tsource = wela o ke kumu wela, Tambient = wela o ke kaiapuni a puni, a me Q = ka wela wela (ma Watts).

Hōʻike ʻia nā puʻupuʻu wela fin skivedpale wela haʻahaʻa, ʻo ia ke ana o ka hoʻoili ʻana o ka wela i ka wela mai ke kumu a i ke kaiapuni a puni.ʻOi aku ka nui o ka ʻili me ka ratio o ka ʻili wela o ka skived finextrusion wela wela, ʻoi aku ka maikaʻi o ka hoʻopau ʻana i ka wela.

2. Heat Dissipation: No ka mea, ʻoi aku ka lahilahi o nā paia o nā ʻili skived i hoʻohālikelike ʻia me nā fins extruded, e hopena i kahi ʻāpana ili nui no ka hoʻoili wela.ʻOi aku ka nui o ka hoʻopili ʻana o nā ʻili skived me ke kumu wela, kahi e hopena aiʻoi aku ka wela wela.Hiki i ke kaʻina hana skiving ke hiki ke maʻalahi i ka hoʻolālā ʻana i ka geometry hope, e hiki ai i ka hoʻoili wela ʻoi aku ka maikaʻi

3. Ke kaumaha a me ka nui: ʻO ka mea maʻamau ka hoʻopaʻa ʻana i ka wela welamāmā a liʻiliʻima mua o nā ʻano mea wela ʻē aʻe.He mea kūpono kēia no ka hoʻohana ʻana i nā mea uila liʻiliʻi me nā wahi liʻiliʻi i loaʻa no nā ʻōnaehana hoʻomaha.

4. Paʻakikī o ka hana ʻana: Skived fin heat sink manufacturing isʻoi aku ka paʻakikī a me ke kumukūʻaihoʻohālikelike i ka extrusion heat sink manufacturing.Pono ka hana ʻana i nā mea hoʻomaʻamaʻa skived fin i nā mea hana kūikawā a me nā limahana akamai.No laila, ʻo ka hoʻoheheʻe wela ʻo skivedʻoi aku ka maikaʻi no ka helu kauoha liʻiliʻi.

5. ʻAi Paʻi ʻino: Hiki ke ʻino ʻia nā puʻu wela i hana ʻia mai ka aluminika a i ʻole ke keleawe ke ʻike ʻia i nā kemika, ka haʻahaʻa, a i ʻole nā ​​mea ʻē aʻe., no laila pono mākou e hana i ka mālama ʻana no lākou, skived fin heat sinksuhi ʻia me kahi ʻano mea palee pale i ka pala.

Ma ke ʻano holoʻokoʻa, ua hoʻolālā ʻia kahi wai wela skived fin e hōʻemi i ka pale ʻana i ka wela, e hopenahoʻopau wela kūponoa me nā mahana haʻahaʻa ma ke kumu wela.Hoʻopili ʻia ka pale ʻana o ka wela wela o kahi pā wela skived fin e nā mea e like me ka geometry fin, nā waiwai waiwai, a me ke ʻano o ka hana ʻana.ka wela wela kiʻekiʻe a me ka nui paʻa, e hoʻolilo iā lākou i mea kūpono no ka hoʻohana ʻana i nā noi mana kiʻekiʻe me ka palena palena no nā ʻōnaehana hoʻomaha.
