I ka honua o ka cryogenics, ʻo ka pono no ka hoʻokaʻawale wela kūpono a hilinaʻi nui ka mea nui, ʻoi aku ka nui o ka lawe ʻana i nā wai supercooled e like me ka helium wai.ʻO nā paipu i hoʻopaʻa ʻia i ka ʻawaʻawa(VJP) he ʻenehana koʻikoʻi i ka hōʻemi ʻana i ka hoʻoili wela a me ka hōʻoia ʻana i ka noho ʻana o nā wai cryogenic e like me ka helium wai i nā haʻahaʻa haʻahaʻa i makemake ʻia i ka wā o ka lawe ʻana. Ke ʻimi nei kēia ʻatikala i ka hana koʻikoʻi o nā paipu ʻaʻahu ʻaʻahu i loko o nā noi helium wai.

He aha nā paipu ʻaʻahu ʻaʻahu?

ʻO nā paipu i hoʻopaʻa ʻia i ka ʻawaʻawa, ʻike ʻia hoʻi ʻo nā paipu insulated, he mau paipu kūikawā e hōʻike ana i kahi papa insulation vacuum ma waena o nā paia paipu concentric. Hana ʻia kēia ʻāpana ʻūhā ma ke ʻano he pale wela maikaʻi loa, e pale ana i ka hoʻoili ʻana o ka wela a i ʻole mai nā mea o ka paipu. No ka helium wai, e paila ana ma kahi o 4.2 Kelvin (-268.95°C), he mea nui ka mālama ʻana i nā wela haʻahaʻa i ka wā e hele ai i mea e pale aku ai i ka evaporation a me ka nalowale o nā mea.

ʻO ke koʻikoʻi o nā paipu i hoʻopaʻa ʻia i loko o nā ʻōnaehana Helium Liquid

Hoʻohana nui ʻia ka helium wai i nā ʻoihana e like me ka mālama ola kino (no nā mīkini MRI), ka noiʻi ʻepekema (i nā mea hoʻokele particle), a me ka ʻimi ʻana i ka lewa (no ka hoʻoluʻu ʻana i nā ʻāpana mokulele). ʻO ka lawe ʻana i ka helium wai ma nā mamao me ka piʻi ʻole o ka mahana he mea koʻikoʻi no ka hōʻemi ʻana i ka ʻōpala a me ka hōʻoia ʻana i ka pono o ke kaʻina hana.ʻO nā paipu i hoʻopaʻa ʻia i ka ʻawaʻawaua hoʻolālā ʻia e mālama i ka wai i kona mahana e pono ai ma o ka hoʻemi nui ʻana i ka hoʻololi wela.

Hoʻemi ʻia ka loaʻa ʻana o ka wela a me ka nalo ʻana

ʻO kekahi o nā pono nui onā paipu ʻaʻahu ʻaʻahui loko o nā ʻōnaehana helium wai ko lākou hiki ke pale i ka komo ʻana o ka wela. Hāʻawi ka papa ʻūhā i kahi pale kokoke loa i nā kumu wela o waho, e hōʻemi nui ana i ka nui o ka paila. He mea koʻikoʻi kēia no ka mālama ʻana i ke kūlana wai o ka helium i ka wā o ka lawe ʻana i nā mamao lōʻihi. Me ka ʻole o ka hoʻohana ʻana i ka insulation vacuum, e mahuka koke ka helium, e alakaʻi ana i nā poho kālā a me nā hemahema o ka hana.

Ka lōʻihi a me ka maʻalahi

ʻO nā paipu i hoʻopaʻa ʻia i ka ʻawaʻawahoʻohana ʻia i loko o nā ʻōnaehana helium wai i hoʻolālā ʻia no ka lōʻihi, i hana pinepine ʻia me ke kila kila a i ʻole nā ​​​​mea ʻē aʻe e hiki ke kū i nā mahana wela a me ke koʻikoʻi mechanical. Hele mai kēia mau paipu i nā hoʻolālā maʻalahi, e ʻae i ka hoʻokomo maʻalahi i nā ʻōnaehana e koi ai i nā ala curved a i ʻole. ʻO kēia maʻalahi ka mea kūpono no nā ʻenehana paʻakikī e like me nā laboratories, cryogenic storage tanks, a me nā ʻoihana kaʻa.

Ka hopena

ʻO nā paipu i hoʻopaʻa ʻia i ka ʻawaʻawapāʻani i ka hana koʻikoʻi i ka lawe ʻana i ka helium wai, e hāʻawi ana i ka insulation thermal maikaʻi loa e hōʻemi i ka loaʻa ʻana o ka wela a hōʻemi i ka nalowale. Ma ka mālama ʻana i ka pono o nā wai cryogenic, kōkua kēia mau paipu i ka mālama ʻana i ka helium waiwai a hoʻemi i nā kumukūʻai hana. Ke hoʻomau nei nā ʻoihana i ka hana hou a koi aku i nā ʻōnaehana cryogenic kiʻekiʻe, ke kuleana onā paipu ʻaʻahu ʻaʻahue ulu wale ana ka mea nui. Me kā lākou hana wela like ʻole a me ka lōʻihi,nā paipu ʻaʻahu ʻaʻahue noho mau i ka ʻenehana koʻikoʻi ma ke kahua o ka cryogenics, ʻoi aku ka nui o nā noi helium wai.

I ka hopena,nā paipu ʻaʻahu ʻaʻahu(VJP) he mea koʻikoʻi i nā noi helium wai, e hiki ai i ka halihali kūpono, e hōʻemi i ka ʻōpala, a me ka hōʻoia ʻana i ka palekana a me ka hilinaʻi o nā ʻōnaehana cryogenic.
