yasungulwa nini i-vacuum flask

I-thermos iyinto yasendlini etholakala yonke indawo eguqule indlela esigcina futhi sidle ngayo iziphuzo ezishisayo nezibandayo.Idizayini yayo ehlakaniphile isivumela ukuthi sijabulele iziphuzo esizithandayo ngezinga lokushisa esilifunayo, kungakhathaliseki ukuthi sisohambweni lomgwaqo noma sihlezi etafuleni lethu.Kodwa ingabe wake wazibuza ukuthi lokhu kusungulwa okuphawulekayo kwavela nini?Ngijoyine ohambweni lokudlula isikhathi ukuze uthole umsuka we-thermos kanye nokucabanga okunamandla ngemuva kokudalwa kwayo.

Isungulwe:

Indaba ye-thermos iqala ngoSir James Dewar, usosayensi waseScotland ekhulwini le-19.Ngo-1892, uSir Dewar wagunyaza i-“thermos” entsha, umkhumbi oguquguqukayo ongagcina uketshezi lushisa noma lubanda isikhathi eside.Wakhuthazwa ukuhlola kwakhe okungokwesayensi ngamagesi ancibilikisiwe, okwakudinga ukugqunywa ukuze kugcinwe izinga lokushisa elibi kakhulu.

Ukutholwa kukaDewar kwaphawula ingqopha-mlando ebalulekile emkhakheni we-thermodynamics.Amabhodlela evacuum, aziwa nangokuthi amabhodlela e-Dewar, aqukethe isitsha esinezindonga ezimbili.Isiqukathi esingaphakathi sibamba uketshezi, kuyilapho isikhala phakathi kwezindonga sivalwe nge-vacuum ukuze kuncishiswe ukudluliswa kokushisa ngokusebenzisa i-convection kanye nokuhanjiswa.

Ukuhwebelana Nokuthuthuka:

Ngemuva kokuthi u-Dewar enelungelo lobunikazi, ibhodlela le-vacuum lathuthukiswa ngabasunguli abahlukahlukene nezinkampani.Ngo-1904, umshini wengilazi waseJalimane u-Reinhold Burger wathuthuka ekwakhiweni kwe-Dewar ngokufaka imvilophu yengilazi eqinile esikhundleni somkhumbi wangaphakathi.Lokhu kuphindaphinda kube yisisekelo se-thermos yesimanje esiyisebenzisayo namuhla.

Nokho, kwaze kwaba ngo-1911 lapho amaflaski e-thermos athola ukuthandwa kabanzi.Unjiniyela waseJalimane nomsunguli u-Carl von Linde uqhubeke walungisa umklamo ngokungeza ucwecwe olusiliva ekesini lengilazi.Lokhu kuthuthukisa ukufakwa kwe-thermal, okwandisa ukugcinwa kokushisa.

Ukutholwa nokuduma emhlabeni wonke:

Njengoba umhlaba wonke uthola umoya wamakhono amangalisayo we-thermos, yathola ukuthandwa ngokushesha.Abakhiqizi baqala ukukhiqiza amabhodlela e-thermos ngobuningi, okwenza afinyeleleke kubantu abavela kuzo zonke izigaba zokuphila.Ngokufika kwensimbi engagqwali, ikesi lathola ukuthuthuka okukhulu, elinikeza ukuqina nobuhle obushelelekayo.

Ukuguquguquka kwe-thermos kuyenza ibe yinto yasendlini ngokusetshenziswa okuningi.Sekuyithuluzi elibalulekile kubahambi, abakhempa, nabafuna ukuzidela, elibenza bakwazi ukujabulela isiphuzo esishisayo ohambweni lwabo lokuzidela.Ukuduma kwayo kugqugquzelwe nakakhulu ukubaluleka kwayo njengesiqukathi esiphathwayo nesithembekile seziphuzo ezishisayo nezibandayo.

I-Evolution kanye ne-contemporary innovation:

Emashumini eminyaka amuva nje, amabhodlela e-thermos aqhubekile nokuvela.Abakhiqizi bethule izici ezifana nemishini yokuthela elula, izinkomishi ezakhelwe ngaphakathi, ngisho nobuchwepheshe obukhaliphile obulandelela futhi buqaphe amazinga okushisa.Le ntuthuko ibhekelela izidingo ezithile kanye nokuthandwa ngabathengi, okwenza amabhodlela e-thermos abe yingxenye ebalulekile yokuphila kwethu kwansuku zonke.

Uhambo olumangalisayo lwe-thermos ukusuka ekuhlolweni kwesayensi kuya ekusetshenzisweni kwansuku zonke luwubufakazi bobuhlakani bomuntu kanye nesifiso sokuthuthukisa okuhlangenwe nakho kwethu kwansuku zonke.USir James Dewar, Reinhold Burger, Carl von Linde kanye nabanye abangenakubalwa baphendla indlela yalokhu kusungulwa okuyisakhiwo sodumo, okwenza ukuthi Sikwazi ukuphuza iziphuzo zethu esizithandayo ngezinga lokushisa elifanele noma nini, noma kuphi.Njengoba siqhubeka nokwamukela nokusungula lokhu kusungulwa okungaphelelwa yisikhathi, i-thermos isalokhu iwuphawu lokunethezeka, ukusimama kanye nobuhlakani bomuntu.
