Ngaba uye wakha wazibuza ukuba i-thermos inokugcina isiselo sakho sishushu iiyure kungakhathaliseki ukuba iimeko zemozulu ngaphandle?Iibhotile ze-Thermos, ezikwabizwa ngokuba zii-thermoses, ziye zaba sisixhobo kwabo bathanda ukonwabela iziselo zabo kubushushu obufanelekileyo.Kule bhlog, siza kungena kwisayensi emva kweebhotile ze-thermos kwaye sityhile umlingo osemva kokukwazi kwabo ukugcina iziselo zishushu ixesha elide.
Funda ngefiziksi:
Ukuze siqonde indlela i-thermos esebenza ngayo, kufuneka siqale siqonde imithetho yefiziksi.I-thermos yenziwe ngamalungu amathathu angundoqo: ibhotile yangaphakathi, ibhotile yangaphandle, kunye ne-vacuum layer eyahlula ezimbini.Ibhotile yangaphakathi ngokuqhelekileyo yenziwe ngeglasi okanye insimbi engenasici kwaye isetyenziselwa ukubamba iziselo.Ibhotile yangaphandle yenziwe ngentsimbi okanye iplastiki kwaye isebenza njengomaleko okhuselayo.Umaleko we-vacuum phakathi kweendonga ezimbini udala ukugquma ngokuphelisa ukuhanjiswa kobushushu obuqhubayo okanye obubambekayo.
Thintela ukugqithiswa kobushushu:
I-Conduction kunye ne-convection yizona zizathu eziphambili zokutshintshwa kobushushu.Iibhotile ze-Thermos ziyilwe ngononophelo ukunciphisa zombini ezi nkqubo.Umaleko wevacuum phakathi kweendonga zangaphakathi nangaphandle zeflask kunciphisa kakhulu ukuhanjiswa kobushushu obusebenzayo.Oku kuthetha ukuba ukushisa okushushu okanye okubandayo kwesiselo kugcinwa ngaphakathi kwebhotile yangaphakathi ngaphandle kobushushu obungaphandle.
Ukongeza, iiflaski ze-thermos zihlala zinendawo ekhanyayo, enje ngesilivere, ukuchasana nokugqithiswa kobushushu ngemitha.Le miphezulu ibonakalisa inceda ukubonakalisa ubushushu obuvela kwisiselo bubuyele kwiflask, buthintele ukuba bungaphumi.Ngenxa yoko, iziselo zinokugcinwa kwiqondo lobushushu elifunekayo ixesha elide.
Umlingo wokutywina:
Enye into ephambili kuyilo lwe-thermos yindlela yokutywina.Izithinteli okanye izivalo zeeflask ziyilwe ngononophelo ukuqinisekisa ukuba akukho moya ungangeni.Oku kuthintela nawuphi na umoya wangaphandle ukuba ungene kwaye uphazamise indawo elawulwayo ngaphakathi kwe-thermos.Ngaphandle kwesi sitywina siqinile, ukuhanjiswa kobushushu kwenzeka nge-convection, kunciphisa kakhulu amandla eflask ukugcina ubushushu besiselo.
Khetha imathiriyeli efanelekileyo:
Ukukhethwa kwezinto ezisetyenziselwa ukwakha i-thermos nayo idlala indima ebalulekileyo kwiimpawu zayo zokukhusela.Insimbi engenasici lukhetho oludumileyo lwee-liners ngenxa yezinto ezigqwesileyo zokugquma.I-conductivity ephezulu ye-thermal yensimbi engenasici inceda ukusabalalisa ukushisa ngokulinganayo kuyo yonke imixholo yolwelo.Kwelinye icala, iiflaski zangaphandle zihlala zisebenzisa izixhobo ezine-thermal conductivity ephantsi, njengeplastiki okanye iglasi, ukuqinisekisa ukuba ubushushu buhlala ngaphakathi.
ukuququmbela:
Ke kwixesha elizayo xa usela kwi-thermos kwaye uziva ubushushu besiselo osithandayo, khumbula inzululwazi ngasemva kwesakhono sayo esimangalisayo sokubamba ubushushu.I-Thermoses isebenza ngokunciphisa ukuhanjiswa kobushushu ngokusebenzisa i-conduction, i-convection kunye ne-radiation.Umaleko wevacuum ubonelela ngokugquma, umphezulu obonakalisayo umelana nemitha, kwaye isitywina se-hermetic sithintela ukulahleka kobushushu obuguqukayo.Ukudibanisa zonke ezi mpawu kunye nezinto ezikhethwe ngononophelo, i-thermos iye yaba yinto enobuchule eye yaguqula indlela esinandipha ngayo iziselo.
