momwe vacuum botolo imalepheretsa kutentha

Kodi munayamba mwadzifunsapo kuti chakumwa chanu chotentha chidzatentha bwanji kwa maola ambiri, ngakhale m'masiku ozizira kwambiri kapena paulendo wautali?Yankho lagona paukadaulo wodabwitsa womwe uli kumbuyo kwa thermos (yomwe imadziwikanso kuti thermos).Chifukwa cha mapangidwe ake apadera komanso kutchinjiriza kolimba, kupangidwa mwanzeru kumeneku kumapangitsa zakumwa zanu kukhala zotentha kapena zozizira kwa nthawi yayitali.Mu blog iyi, tiwona sayansi yochititsa chidwi ya momwe ma thermoses amatetezera kutentha kutentha.

Kumvetsetsa lingaliro la thermos:
Poyang'ana koyamba, thermos imawoneka ngati chidebe chosavuta chokhala ndi screw top.Komabe, mphamvu yake pakusunga kutentha kwa zomwe zili mkati mwake zimadalira momwe imapangidwira.Thermos imapangidwa ndi zigawo ziwiri zazikulu: chigoba chakunja ndi chidebe chamkati, chomwe nthawi zambiri chimapangidwa ndi galasi, chitsulo chosapanga dzimbiri, kapena pulasitiki.Zigawo ziwirizi zimasiyanitsidwa ndi chosanjikiza cha vacuum chomwe chimapanga chotchinga cha kutentha chomwe chimachepetsa kutentha kwa kutentha.

Kupewa conduction:
Imodzi mwa njira zomwe ma thermoses amalepheretsa kutentha kutentha ndikuchepetsa kuwongolera.Kuchititsa ndi njira yomwe kutentha kumasunthidwa kuchokera ku chinthu chimodzi kupita ku chinthu china pamene zinthuzo zikugwirizana.Mu thermos, galasi lamkati kapena chidebe chachitsulo (chokhala ndi madzi) chimazunguliridwa ndi wosanjikiza, kuchotsa kukhudzana kwachindunji ndi chipolopolo chakunja.Kupanda kukhudzana kumeneku kumalepheretsa kusuntha kwa kutentha ndi conduction, potero kusunga kutentha komwe kumafunikira mkati mwa botolo.

Chotsani convection:
Convection, njira ina yosinthira kutentha, imachepetsedwa kwambiri mu thermos.Convection imachitika kudzera mukuyenda kwa tinthu tambiri totentha mkati mwamadzi kapena gasi.Popanga vacuum wosanjikiza, botolo limapondereza kusuntha kwa tinthu ting'onoting'ono, potero kuchepetsa mwayi wotaya kutentha kudzera mu convection.Izi zimatsimikizira kuti kutentha kwa madzi otentha mu botolo kumakhalabe kokhazikika kwa nthawi yaitali, kuteteza kuzizira mofulumira kwa madzi otentha mu botolo.

Kutentha Kwamawonekedwe:
Ma radiation ndi njira yachitatu yosinthira kutentha, yomwe imayankhulidwa ndi zinthu zowunikira za thermos.Kutaya kwa kutentha kwamphamvu kumachitika pamene chinthu chotentha chimatulutsa cheza cha kutentha, kusamutsira mphamvu ku chinthu chozizira.Ma thermoses amakhala ndi zinthu zowala kapena zokutira, monga siliva kapena aluminiyamu, kuti achepetse kufalikira kwa ma radiation.Magawo onyezimirawa amawonetsa kutentha kowala, ndikusunga mkati mwa chidebe chamkati ndikuchepetsa kutayika kwa kutentha.

Insulation yowonjezera yokhala ndi zigawo zowonjezera:
Ma thermoses ena amaphatikizirapo kusungunula kowonjezera kuti apereke chitetezo china pakutaya kutentha.Zigawozi nthawi zambiri zimapangidwa ndi thovu kapena zinthu zina zotchingira ndipo zimathandizira kukulitsa luso lachitetezo cha botolo.Powonjezera magawo owonjezerawa, thermos imatha kukhala yotentha kwa nthawi yayitali, ndikupangitsa kuti ikhale bwenzi labwino kwambiri loyenda panja kapena kuyenda kwautali.
Thermos yamakono ndi sayansi yodabwitsa, yopangidwira kuti zakumwa zomwe mumakonda zizikhala zotentha kuti muzisangalala nazo nthawi iliyonse, kulikonse.Kupyolera mu kuphatikizika kwa matekinoloje ochepetsera kutentha kwa conductive, convective ndi kunyezimira komanso kusungunula kowonjezera, thermos imachepetsa kutayika kwa kutentha kotero kuti mutha kusangalala ndi chakumwa chanu chotentha pa liwiro lanu.Ndiye nthawi ina mukadzamwa madzi mu botolo ndikumva kutentha kotonthoza, yamikirani sayansi yovuta yomwe ikugwira ntchito mu chinthu chosavuta cha tsiku ndi tsiku ichi.
