Vacuum Double Wall Luxury Insulated Water Bottle yokhala ndi Handle

Makapu a Thermos ndizofunikira kwambiri pamoyo watsiku ndi tsiku wa anthu.Anthu ambiri amakonda kumwa madzi otentha, ndipo kapu ya thermos imatha kusunga kutentha kwa madzi, kotero kuti aliyense amagwiritsa ntchito nthawi yozizira.Nanga n’cifukwa ciani ungakhale wofunda, kodi mukuidziŵa mfundo yake?

Chikho cha thermos chimapangidwa kuchokera ku botolo la thermos.Mfundo yotetezera kutentha ndi yofanana ndi ya botolo la thermos.Pofuna kunyamula, botolo limapangidwa kukhala kapu.M'mbuyomu, anthu ankagwiritsa ntchito mabotolo a thermos kusunga madzi otentha.Mabotolo a thermos amatchedwanso mabotolo a thermos, mabotolo amadzi otentha kapena miphika ya thermos.Pakamwa patsekeka ndi chitsekerero.

Botolo lamakono la vacuum linapangidwa mu 1892 ndi katswiri wa sayansi ya ku Britain, Sir James Dewar.Pa nthawiyo, iye anali kuchita kafukufuku wa liquefying gasi.Kuti asungunuke mpweya pa kutentha kocheperako, choyamba anafunikira kupanga chidebe chimene chikanachotsa mpweyawo ku kutentha kwa kunja.Choncho anapempha Berg, katswiri wa magalasi, kuti amuwuzire mabotolo awiri.Magalasi awiri osanjikiza chidebe, makoma amkati mwa zigawo ziwirizo amakutidwa ndi mercury, ndiyeno mpweya pakati pa zigawo ziwirizo umayamwa kuti ukhale wosanjikiza.Botolo la vacuum lotere limatchedwanso "Du botolo", lomwe limatha kusunga kutentha kwamadzi momwemo kosasinthika kwa nthawi inayake posatengera kuzizira kapena kutentha.

Pali njira zitatu zotumizira kutentha: kutulutsa kutentha, kutulutsa kutentha ndi kutulutsa kutentha.Mphepete mwa botolo la madzi otsekedwa ndi galasi lawiri-wosanjikiza, ndipo pakati amatsukidwa kuti achepetse kutentha;galasi lagalasi latsekedwa ndi cork lomwe silophweka kutentha kutentha, ndipo madzi otentha amatha kutsanulidwa kuti achepetse kutentha;chotchingacho chimakutidwa pakati pa magalasi awiri osanjikiza Silver, omwe amatha kuwonetsa kutentha mkati mwa botolo kumbuyo.Osachepetsa botolo laling'ono lililonse la thermos, limagwiritsa ntchito njira zitatu zosinthira kutentha kuti zikwaniritse bwino kuteteza kutentha.

Chingwe choyambirira cha chikho cha thermos chinali chamkati cha botolo laling'ono lamadzi la thermos, koma kuti amwe mowa, kamwa lamkati lamkati lidatseguka.Ndi chitukuko cha anthu, mtundu uwu wa galasi losalimba la galasi la thermos chikho sichinawonekere kawirikawiri, ndipo makapu ambiri a thermos amapangidwa ndi zitsulo zosapanga dzimbiri, koma mfundo yotetezera kutentha ndi yofanana.

Botolo lamadzi osapanga dzimbiri la thermos lili ndi magawo awiri, ndipo thanki yamkati ndi thupi la chikho zimalumikizidwa palimodzi kuti apange vacuum, yomwe sisuntha kutentha;tambala wa botolo lamadzi la thermos ali ndi ntchito yabwino yosindikiza, ndipo kutayika kwa kutentha kumakhala kochepa kwambiri kudzera mu convection.Mkuwa kapena siliva amakutidwa pakati pa thanki yamkati ndi zigawo ziwiri zazitsulo zosapanga dzimbiri pamutu wa chikho, zomwe zimatha kuchepetsa kutentha komwe kumatayika ndi ma radiation.Mabotolo amadzi opangidwa ndi chitsulo chosapanga dzimbiri ndi osavuta kunyamula, okhazikika komanso osavuta kuyeretsa, ndipo pang'onopang'ono asanduka okondedwa atsopano pamsika.

Nthawi zambiri, gawo loyipa kwambiri la botolo la thermos ndi botolo, kotero kapu ya thermos yokhala ndi mphamvu yayikulu komanso kakamwa kakang'ono kamakhala ndi mphamvu yoteteza kutentha.Poyenda pagalimoto kapena kuchita masewera akunja, chikho chachikulu cha thermos chimakhala chida chofunikira.

Thermos imasunga kutentha osati kutentha, kotero sikuti imangosunga madzi otentha pa kutentha kwina, koma imatha kusunga zinthu monga sorbet pa kutentha kwina.Mapangidwe a kapu ya thermos amachititsa kuti kutentha kwa mkati kukhale kovuta, ndipo sikophweka kuti kutentha kunja kulowe mkati, kotero kuti kapu ya thermos imatha "kutentha" ndi "kuzizira".
