Paipu hoʻoheheʻe U-ʻano ʻelua.

Hōʻike huahana

ʻO ka pahu hoʻoheheʻe U-shaped, ʻike ʻia hoʻi ʻo ka heterosexual heating tube, he paipu metala maʻemaʻe (ʻo ke kila kila, ka pahu titanium, ke kila kila kila, ka pahu keleawe) i loko o ka uea hoʻomehana uila, a hoʻopiha piha ʻia ka ʻāpana me ka wela maikaʻi. conductivity a me ka insulation o ka crystalline magnesium oxide, ua hoʻohui ʻia nā ʻaoʻao ʻelua o ka uea hoʻomehana uila me ka mana mana ma o nā koʻokoʻo alakaʻi ʻelua, ua hoʻopiha ʻia ka ʻāpana āpau me ka conductivity thermal maikaʻi a me ka insulation o ka pauka magnesium oxide ma hope o ka paipu.No ka mea, ua ʻāwili ʻia ka paipu wela uila e like me ka leka Pelekane U, ua kapa ʻia ʻo ia ʻano U-type uila wela.

Hiki ke hoʻohana ʻia ka paipu wela uila U-type no ka hoʻomehana ʻana i nā ʻano wai like ʻole a me ka waikawa, ka alkali a me ka paʻakai, akā kūpono hoʻi no ka wahi haʻahaʻa haʻahaʻa o ka hoʻomehana metala a me ka hoʻoheheʻe ʻana (lead, zinc, tin, babbitt).
