momwe botolo la vacuum limachepetsa conduction convection ndi radiation

Mabotolo a Thermos, omwe amadziwikanso kuti vacuum flasks, ndi chida chabwino kwambiri chosungira zakumwa kutentha kapena kuzizira kwa nthawi yayitali.Kuphatikiza pa kuphweka, thermos ili ndi njira yotchinjiriza yapamwamba yomwe imachepetsa kutentha kutentha kudzera mu conduction, convection, ndi radiation.M'nkhaniyi, tiwona momwe thermos imakwaniritsira izi.

1. Chepetsa kuchititsa:

Kuchititsa ndi kusamutsa kutentha kudzera kukhudzana mwachindunji pakati pa zipangizo ziwiri.Pofuna kuchepetsa ma conduction mu botolo la vacuum, botolo la vacuum limakhala ndi magawo awiri opangidwa ndi zinthu zotsika kwambiri zamatenthedwe.Nthawi zambiri, vacuum imapangidwa pakati pa makoma awiri achitsulo chosapanga dzimbiri.Chitsulo chosapanga dzimbiri ndi chisankho chabwino chifukwa chimalepheretsa kutentha kuchitidwa mosavuta kudzera pamwamba pake.Vacuum layer imagwira ntchito ngati insulator, kuchotsa sing'anga iliyonse yomwe kutentha kumatha kuchitika.

2. Chepetsani kutembenuka:

Convection ndi kusamutsa kutentha ndi kayendedwe ka madzi kapena gasi.Thermos imalepheretsa kusuntha pochotsa malo pakati pa makoma amkati ndi akunja, ndikuchotsa kuthekera kulikonse kwa mpweya kapena kuyenda kwamadzi.Kutsika kwa mpweya mkati mwa botolo kumalepheretsanso kutentha kwa kutentha, komwe kumalepheretsa kutentha kuchokera kuzinthu zamadzimadzi kupita kumalo ozungulira botolo.

3. Pewani ma radiation:

Radiation ndi kusamutsa mphamvu yotentha kudzera mu mafunde a electromagnetic.Vacuum flasks bwino kuchepetsa kutentha macheza kudzera njira zosiyanasiyana.Choyamba, kuwala kwamkati kwa botolo kumachepetsa matenthedwe a kutentha powonetseranso kutentha kwamadzimadzi.Liner yonyezimirayi imaperekanso kutha kosalala komwe kumachepetsa kutulutsa kutentha.

Kuphatikiza apo, ma flasks ambiri a thermos amakhala ndi galasi lasiliva kapena chitsulo pakati pa makoma amkati ndi akunja.Chigawochi chimachepetsanso ma radiation powonetsa kutentha kulikonse kubwerera m'madzi, motero kusunga kutentha kwake kwa nthawi yaitali.

Pomaliza, ma flasks a thermos amachepetsa kutengera kutentha kudzera mu conduction, convection ndi radiation kudzera mukupanga kwatsopano komanso kuphatikiza kwa zida.Kumanga kwa mipanda iwiri nthawi zambiri kumapangidwa ndi zitsulo zosapanga dzimbiri, zomwe zimachepetsa kuwongolera kudzera mumayendedwe ake otsika amafuta.Vacuum wosanjikiza amachotsa sing'anga iliyonse yomwe kutentha kumatha kuchitika, kukhala ngati insulator yabwino.Pochotsa danga pakati pa makoma, thermos imalepheretsa kuti convection isapangidwe ndipo, kudzera mu njirayi, imalepheretsa kutentha.Kuphatikiza apo, magalasi owoneka bwino ndi magalasi opangidwa ndi silvered amachepetsa kutentha kwa ma radiation powonetsa kutentha kumadzimadzi.

Umisiri wonsewu umaphatikizana kuti thermos ikhale yogwira mtima posunga kutentha komwe kumafunikira kwa zakumwa, zotentha kapena zozizira, kwa nthawi yayitali.Kaya mukusangalala ndi kapu ya khofi wotentha mukuyenda m'nyengo yozizira, kapena kumwa kapu yamadzi ozizira m'chilimwe chotentha, mabotolo a thermos ndi mabwenzi ofunikira.

Zonsezi, mapangidwe a thermos motsogola komanso kusamalitsa mwatsatanetsatane kumapereka njira yabwino yochepetsera kutentha kudzera mu conduction, convection ndi radiation.Tsanzikanani ndi zakumwa zofunda ndikusangalala ndi chakumwa chomwe mumakonda kwa maola ambiri pakutentha koyenera.
