Wake wazibuza ukuthi i-thermos ingagcina kanjani isiphuzo sakho sishisa amahora kungakhathaliseki ukuthi izimo zezulu ngaphandle zinjani?Amabhodlela e-Thermos, avame ukubizwa ngokuthi ama-thermoses, asephenduke ithuluzi okufanele libe nalo kulabo abathanda ukujabulela iziphuzo zabo ezingeni lokushisa elifanele.Kule bhulogi, sizocubungula isayensi engemuva kwamabhodlela e-thermos futhi siveze umlingo obangela amandla awo okugcina iziphuzo zishisa isikhathi eside.
Funda nge-physics:
Ukuze siqonde ukuthi i-thermos isebenza kanjani, okokuqala sidinga ukuqonda imithetho ye-physics.I-thermos yakhiwe izingxenye ezintathu ezibalulekile: ibhodlela langaphakathi, ibhodlela langaphandle, nongqimba lwe-vacuum oluhlukanisa kokubili.Ibhodlela langaphakathi ngokuvamile lenziwa ngengilazi noma ngensimbi engagqwali futhi lisetshenziselwa ukubamba iziphuzo.Ibhodlela langaphandle lenziwe ngensimbi noma ipulasitiki futhi lisebenza njengongqimba oluvikelayo.Isendlalelo se-vacuum phakathi kwezindonga ezimbili sidala ukwahlukanisa ngokuqeda ukudluliswa kokushisa kwe-convective noma okuguquguqukayo.
Vimbela ukudluliswa kokushisa:
I-Conduction kanye ne-convection yizona zinkinga ezinkulu zokudlulisa ukushisa.Amabhodlela e-Thermos aklanywe ngokucophelela ukuze anciphise zombili lezi zinqubo.Isendlalelo se-vacuum phakathi kwezindonga zangaphakathi nezangaphandle zeflask kunciphisa kakhulu ukudluliswa kokushisa okusebenzayo.Lokhu kusho ukuthi izinga lokushisa elishisayo noma elibandayo lesiphuzo ligcinwa ngaphakathi kwebhodlela elingaphakathi ngaphandle kwezinga lokushisa elingaphandle.
Ukwengeza, amaflaski e-thermos avame ukuqukatha izindawo ezikhanyayo, njengezingubo ezisiliva, ukuze amelane nokudluliswa kokushisa ngemisebe.Lezi zindawo ezicwebezelayo zisiza ukukhombisa ukushisa okuphuma esiphuzweni kubuyele kufulaski, kusivimbele ukuthi singaphumi.Ngenxa yalokho, iziphuzo zingagcinwa ezingeni lokushisa elifunayo isikhathi eside.
Umlingo wokuvala:
Esinye isici esibalulekile ekwakhiweni kwe-thermos indlela yokuvala uphawu.Izivalo noma izivalo zamaflask ziklanywe ngokucophelela ukuze kuqinisekiswe ukuvala umoya.Lokhu kuvimbela noma yimuphi umoya wangaphandle ukuthi ungangeni futhi uphazamise indawo elawulwayo ngaphakathi kwe-thermos.Ngaphandle kwalolu phawu oluqinile, ukudluliswa kokushisa kwenzeka nge-convection, kunciphisa ngokuphawulekayo ikhono leflask lokugcina ukushisa kwesiphuzo.
Khetha impahla efanele:
Ukukhethwa kwezinto ezisetshenziselwa ukwakha i-thermos nakho kudlala indima ebalulekile ezindaweni zayo zokuvikela.Insimbi engagqwali iyinketho ethandwayo yama-liners ngenxa yezakhiwo zayo ezinhle kakhulu zokuvikela.I-thermal conductivity ephezulu yensimbi engagqwali isiza ukusabalalisa ukushisa ngokulinganayo kukho konke okuqukethwe koketshezi.Ngakolunye uhlangothi, ama-flask angaphandle ngokuvamile asebenzisa izinto ezine-conductivity ephansi ye-thermal, njengepulasitiki noma ingilazi, ukuqinisekisa ukuthi ukushisa kuhlala ngaphakathi.
Ekuphetheni:
Ngakho-ke ngokuzayo uma uphuza ku-thermos futhi uzwa imfudumalo yesiphuzo sakho esiyintandokazi, khumbula isayensi engemuva kwekhono layo elimangalisayo lokubamba ukushisa.Ama-thermoses asebenza ngokunciphisa ukudluliswa kokushisa ngokusebenzisa i-conduction, convection kanye nemisebe.Isendlalelo se-vacuum sihlinzeka nge-insulation, indawo ekhanyayo imelana nemisebe, futhi uphawu lwe-hermetic luvimbela ukulahlekelwa ukushisa okuguquguqukayo.Ihlanganisa zonke lezi zici nezinto ezikhethwe ngokucophelela, i-thermos isiphenduke into ehlakaniphile eye yashintsha indlela esijabulela ngayo iziphuzo.
