Amabhodlela e-thermos, aziwa kakhulu ngokuthi ama-vacuum flask, aseyinto okufanele abantu babe nayo kwabaningi.Zisivumela ukuthi sigcine iziphuzo esizithandayo zishisa noma zibanda isikhathi eside, zizenze zilungele uhambo olude, uhambo lwangaphandle noma nje ukujabulela isiphuzo esishisayo ngosuku olubandayo lwasebusika.Kodwa ingabe wake wazibuza ukuthi i-thermos ikwazi kanjani ukugcina okukuyo ezingeni lokushisa elilawulwayo isikhathi eside?Kule bhulogi, sizocubungula isayensi ebangela ukulahlekelwa ukushisa okuvela kuma-thermoses futhi sifunde ukuthi kungani esebenza ngempumelelo kangaka ekugqumeni.
Funda ngokudluliswa kokushisa:
Ukuze uqonde ukuthi i-vacuum flask ikuqeda kanjani ukushisa, kubalulekile ukuqonda umqondo wokudlulisa ukushisa.Ukushisa kudluliselwa ngokuqhubekayo kusuka ezindaweni eziphakeme lokushisa kuya ezindaweni eziphansi lokushisa ukuze kuzuzwe ukulingana kokushisa.Kunezindlela ezintathu zokudlulisa ukushisa: i-convection, i-convection kanye nemisebe.
I-conduction kanye ne-convection ku-thermos:
I-Thermoses incike ngokuyinhloko ezindleleni ezimbili zokudlulisa ukushisa: i-convection ne-convection.Lezi zinqubo zenzeka phakathi kokuqukethwe kwe-flask nezindonga zangaphakathi nezangaphandle ze-flask.
ukuqhuba:
Ukuqhuba kubhekisela ekudlulisweni kokushisa ngokuthintana okuqondile phakathi kwezinto ezimbili.Ku-thermos, ungqimba olungaphakathi impela olubamba uketshezi ngokuvamile lwenziwa ngengilazi noma ngensimbi engagqwali.Zombili lezi zinto azihambisani kahle namakhondaktha okushisa, okusho ukuthi azikuvumeli kalula ukushisa ukuthi kugeleze kuzo.Lokhu kunciphisa ukudluliselwa kokushisa kusuka kokuqukethwe kweflask kuya endaweni engaphandle.
i-convection:
I-Convection ihilela ukudluliswa kokushisa ngokuhamba koketshezi noma igesi.Ku-thermos, lokhu kwenzeka phakathi koketshezi nodonga lwangaphakathi lweflask.Ingaphakathi le-flask ngokuvamile liqukethe izindonga zezingilazi ezimbili, isikhala phakathi kwezindonga zengilazi sikhishwa kancane noma ngokuphelele.Le ndawo isebenza njenge-insulator, ikhawulela ukunyakaza kwama-molecule omoya futhi inciphisa inqubo yokuguquguquka.Lokhu kunciphisa ngempumelelo ukushisa kusuka oketshezini kuya emoyeni ozungezile.
Imisebe ne-insulating caps:
Nakuba i-conduction ne-convection kuyizindlela eziyinhloko zokulahlekelwa ukushisa ku-thermos, imisebe nayo idlala indima encane.Imisebe ibhekisela ekudlulisweni kokushisa ngamagagasi kagesi.Kodwa-ke, amabhodlela e-thermos anciphisa ukulahlekelwa ukushisa okukhazimulayo ngokusebenzisa izimbotshana ezikhanyayo.Lezi zimbotshana zibonisa ukushisa okukhazimulayo emuva kufulaski, zivimbele ukuthi ungaphumi.
Ngaphezu kokufakwa kwe-vacuum, i-thermos nayo ifakwe isivalo esifakiwe.Isivalo siphinde sinciphise ukulahlekelwa ukushisa ngokunciphisa ukushintshanisa kokushisa okuqondile phakathi koketshezi nomoya ongaphandle kweflask.Idala umgoqo owengeziwe, oqinisekisa ukuthi isiphuzo sakho sihlala ezingeni lokushisa olifunayo isikhathi eside.
Ukwazi ukuthi i-thermos ikuqeda kanjani ukushisa kusisiza ukuba sazise isayensi nobunjiniyela obuhilelekile ekudaleni uhlelo oluhle kangaka lokufakwa kwamanzi.Ngokusebenzisa inhlanganisela ye-convection, i-convection, imisebe nezivalo ezivalekile, lawa maflask ahle kakhulu ekugcineni izinga lokushisa esilidingayo isiphuzo sakho, noma kushisa noma kubanda.Ngakho-ke ngokuzayo uma uphuza inkomishi yekhofi eshisayo noma ujabulela isiphuzo esibandayo amahora ngemva kokugcwalisa i-thermos yakho, khumbula isayensi yokugcina izinga lokushisa elilungile.
