He aha ka mīkini wiliwili wahi i hoʻohana ʻia no ka wili ʻana i nā alumini alumini?

I ka wā e kuʻi ai i nā alumini alumini, ʻo nā koho mua e hoʻokomo pinepine i ka hoʻoponopono lua ʻekolunā mīkini wiliwili wahia me nā mīkini wiliwili wahi mālama ikehu. Ua koho ʻia kēia mau mīkini no ka mea he kiʻekiʻe ka conductivity uila a me ka conductivity thermal.

ʻAʻole maikaʻi nā mīkini wiliwili ʻokoʻa AC maʻamau i ka hoʻomehana ʻana i ka wahi hoʻoheheʻe i kahi kūlana heheʻe a i ʻole ka plastik e hana i kahi weld nugget. Eia kekahi, hiki i nā ʻili alumini ke hana i kahi kiʻiʻoniʻoni oxide. ʻOi aku ka kiʻekiʻe o ka helu heheʻe o ka alumini oxide (kokoke i ka 2000 degere) i ka hoʻohālikelike ʻia me ka helu heheʻe alumini o 660 degere. No laila, he mea koʻikoʻi ka wāwahi ʻana i ka papa oxide a me ka hoʻomehana ʻana i ka weld nugget i ke koho ʻana i kahi mīkini wiliwili wahi alumini.

Wahi a Joule's Law Q=I²Rt, ma muli o ke kiʻekiʻe o ka uila uila a me ke ʻano palupalu o nā alumini alumini, pono e loaʻa i nā mīkini wiliwili wahi kahi puka nui o kēia manawa, kiʻekiʻe ka wela wela, a me ka haʻahaʻa haʻahaʻa. ʻAʻole e like me nā kikoʻī palupalu maʻamau, ʻaʻole hiki ke hoʻohana i ka wiliwili wahi alumini alumini e hoʻohana i nā manawa wili lōʻihi akā pono nā lōʻihi pōkole me ke kiʻekiʻe o kēia manawa.

Me ka hoʻokomo ʻana i nā mīkini wiliwī wahi DC, ʻo kā lākou mau hiʻohiʻona o ka hoʻoponopono ʻana i ka hawewe piha a me ka hoʻopuka pololei ʻana i kēia manawa ua hoʻomaikaʻi maikaʻi ʻia ka maikaʻi o ka wela a me ka hopena i ka wā o ka wili ʻana. He ʻokoʻa kēia i nā hemahema o ka hoʻoponopono semi-wave i nā mīkini hoʻoponopono kiʻekiʻe ʻekolu a me ka manawa hoʻokuʻu o nā mīkini mālama ikehu. Mai ka ʻike ʻia ʻana o nā mīkini wiliwili wahi DC DC, ua lilo koke lākou i koho i koho ʻia no ka wiliwili ʻana i nā alumini alumini.

E haʻi aku wau iā ʻoe, ma muli o kāna lako mana ʻekolu-phase kaulike, ka hoʻopuka pololei ʻana i kēia manawa, a me ka manawa hoʻopaʻa hoʻopaʻa ʻia, ʻo ka mīkini hoʻololi ʻokoʻa DC wahi wiliwili ka mea i koho ʻia no ka wiliwili ʻana i nā alumini alumini.
