Ezweni lanamuhla elisheshayo, sithembele ezinhlobonhlobo zamathuluzi namagajethi ukwenza ukuphila kwethu kwansuku zonke kube lula.Enye into entsha enjalo kwakuyiflask yevacuum, eyaziwa nangokuthi i-vacuum flask.Lesi sitsha esiphathekayo nesisebenza kahle siguqule indlela esigcina futhi sihambisa ngayo iziphuzo ezishisayo noma ezibandayo, sizigcine ezingeni lokushisa esilifunayo isikhathi eside.Kodwa ingabe wake wazibuza ukuthi i-thermos isebenza kanjani umlingo wayo?Kulokhu okuthunyelwe kwebhulogi, singena emhlabeni othakazelisayo wobuchwepheshe be-thermos futhi sihlole ukuthi kunganciphisa kanjani ngempumelelo ukulahlekelwa ukushisa.
Umqondo wokudlulisa ukushisa:
Ngaphambi kokungena emininingwaneni ye-thermos flasks, kuyadingeka ukuqonda umqondo oyisisekelo wokudlulisa ukushisa.Ukudluliswa kokushisa kungenzeka ngezindlela ezintathu ezihlukene: i-convection, i-convection, kanye nemisebe.I-conduction iwukudlulisa ukushisa ngokuthintana okuqondile phakathi kwezinto ezimbili kuyilapho i-convection iwukudlulisa ukushisa ngokuhamba koketshezi olunjengomoya noma amanzi.Ukukhishwa kwemisebe kuhilela ukudluliselwa kokushisa ngendlela yamagagasi kagesi.
Ukuqonda Ukulahleka Kokushisa Ezitsheni Zomdabu:
Iziqukathi zendabuko, njengamabhodlela noma izinkomishi, ngokuvamile azikwazi ukugcina izinga lokushisa elifunekayo loketshezi ngaphakathi isikhathi eside.Lokhu kubangelwa ikakhulukazi ukulahlekelwa ukushisa okwenziwa izinqubo zokuqhuba kanye ne-convection.Lapho uketshezi olushisayo luthululelwa ebhodleleni elivamile, ukushisa kuqhutshelwa ngokushesha endaweni yangaphandle yesitsha, lapho kukhishwa khona emoyeni ozungezile.Ngaphezu kwalokho, i-convection ngaphakathi kwesitsha isheshisa ukudluliswa kokushisa, okuholela ekulahlekelweni okukhulu kwamandla okushisa.
Umgomo webhodlela le-thermos:
I-thermos yakhelwe ngobuhlakani ukunciphisa ukulahlekelwa ukushisa ngokuhlanganisa izici ezimbalwa ezintsha.Ingxenye ebalulekile eyenza i-thermos ihluke ukwakhiwa kwayo kwezingqimba ezimbili.Izindonga zangaphakathi nezingaphandle ngokuvamile zenziwe ngensimbi engagqwali futhi zihlukaniswe ungqimba lwe-vacuum.Lesi sendlalelo se-vacuum sisebenza njengesivimbeli esisebenza kahle sokushisa, esivimbela ukudluliswa kokushisa ngokuhambisa nokuhamba.
Inciphisa ukudluliswa kokushisa okwenziwayo:
Isendlalelo se-vacuum ku-flask siqeda ukuthintana okuqondile phakathi kwezindonga zangaphakathi nangaphandle, kunciphisa kakhulu ukudluliswa kokushisa.Awukho umoya noma indaba ku-vacuum, futhi ukuntuleka kwezinhlayiya ezingadlulisa ukushisa kuqinisekisa ukulahlekelwa okuncane kwamandla ashisayo.Lesi simiso sigcina iziphuzo ezishisayo zifudumele amahora amaningi, okwenza ama-thermoses alungele imisebenzi yangaphandle, uhambo olude noma ngisho nokuhlwa okuthokomele ekhaya.
Vimbela ukudluliswa kokushisa kwe-convective:
Ukwakhiwa kwe-vacuum flask kuphinde kuvimbe i-convection enesibopho sokudlulisa ukushisa okusheshayo.Isendlalelo se-vacuum esivalelayo sivimbela umoya ukuthi ungazungezi phakathi kwezindonga, siqede ukuguquguquka njengendlela yokulahlekelwa ukushisa.Lesi sixazululo esisha sisiza kakhulu ukugcina izinga lokushisa olifunayo isikhathi eside, okwenza i-thermos ibe ukukhetha okuhle kakhulu kokujabulela iziphuzo ezishisayo ekuhambeni.
Ukuvala Idili: Izici Ezengeziwe:
Ngaphezu kokwakhiwa kodonga oluphindwe kabili, amabhodlela e-thermos avame ukuba nezinye izici zokuqinisekisa ukusebenza okuphezulu.Lokhu kungase kuhlanganise izigxivizo ze-silicone ezingangeni moya noma amapulaki erabha avimbela ukulahlekelwa ukushisa ngokuvuleka.Ukwengeza, amanye amaflask anemimbo ecwebezelayo endaweni engaphakathi ukuze kuncishiswe ukudluliswa kokushisa okukhipha imisebe.
Ekuphetheni:
I-thermos iwubufakazi bobuhlakani bomuntu kanye nesifiso sethu esingapheli sokuthuthukisa izixazululo ezisebenzayo ezinseleleni zansuku zonke.Ngokusebenzisa izimiso ze-thermodynamics, lokhu kusungulwa okulula kodwa okuhlakaniphile kunciphisa ngempumelelo ukulahlekelwa ukushisa futhi kugcina iziphuzo zethu zisezingeni eliphezulu lokushisa isikhathi eside.Ngakho-ke noma uphuza inkomishi yekhofi eshisayo ekuseni ekuseni noma ujabulela inkomishi yetiye elineqhwa ngosuku olushisayo lwasehlobo, ungathemba i-thermos yakho ukuthi igcine isiphuzo sakho ngendlela osithanda ngayo - isiphuzo esishisayo noma esishisayo. kuqabula okupholile.
