Iibhotile zeThermos, ezaziwa ngokuba ziiflasks zokufunxa, ziye zayinto eyimfuneko kwabaninzi.Zisivumela ukuba sigcine iziselo zethu esizithandayo zishushu okanye zibanda ixesha elide, zizenza zilungele uhambo olude, uhambo lwangaphandle okanye ukonwabela nje isiselo esishushu ngemini ebandayo yasebusika.Kodwa ngaba wakha wazibuza ukuba i-thermos ikwazi njani ukugcina izinto ezikuyo kwiqondo lobushushu elilawulwayo kangangexesha elide?Kule bhlog, siza kugocagoca kwisayensi emva kokulahleka kobushushu ukusuka kwi-thermoses kwaye sifunde ukuba kutheni zisebenza ngempumelelo kwi-insulating.
Funda malunga nokudluliselwa kobushushu:
Ukuqonda indlela i-vacuum flask echitha ngayo ukushisa, kubalulekile ukuqonda ingcamango yokutshintshwa kobushushu.Ubushushu bufuduswa ngokuqhubekayo ukusuka kwiindawo eziphakamileyo zokushisa ukuya kwiindawo eziphantsi kweqondo lokushisa ukuze kuphunyezwe ukulingana kwe-thermal.Kukho iindlela ezintathu zokuhambisa ubushushu: ukuqhuba, ukuhanjiswa kunye nemitha.
Ukuqhuba kunye nokuhanjiswa kwi-thermos:
I-Thermoses ixhomekeke ngokukodwa kwiindlela ezimbini zokufudumeza ubushushu: ukuqhuba kunye ne-convection.Ezi nkqubo zenzeka phakathi kwemixholo yeflask kunye neendonga zangaphakathi nangaphandle zeflask.
ukuqhuba:
Ukuqhuba kubhekisela ekugqithiseni ubushushu ngokudibana ngokuthe ngqo phakathi kwezinto ezimbini.Kwi-thermos, oyena maleko ungaphakathi obambe ulwelo udla ngokwenziwa ngeglasi okanye ngentsimbi engatyiwayo.Zombini ezi mathiriyeli azikhokhonduki ezilambathayo zobushushu, nto leyo ethetha ukuba azibuvumeli lula ubushushu ukuba buhambe kuzo.Oku kunciphisa ukuhanjiswa kobushushu kwimixholo yeflask ukuya kwindawo yangaphandle.
ukuhambisa:
I-Convection ibandakanya ukuhanjiswa kobushushu ngokushukuma kolwelo okanye igesi.Kwi-thermos, oku kwenzeka phakathi kolwelo kunye nodonga lwangaphakathi lweflask.Ingaphakathi le-flask lihlala liqukethe iindonga zeglasi ezimbini, indawo phakathi kweendonga zeglasi ikhutshwe ngokuyinxenye okanye ngokupheleleyo.Lo mmandla usebenza njenge-insulator, ukuthintela ukuhamba kweeamolekyu zomoya kunye nokunciphisa inkqubo ye-convective.Oku kunciphisa ngokufanelekileyo ilahleko yobushushu ukusuka kulwelo ukuya emoyeni ojikelezileyo.
Imitha kunye ne-insulating caps:
Nangona i-convection kunye ne-convection zezona ndlela ziphambili zokulahleka kobushushu kwi-thermos, i-radiation nayo idlala indima encinci.Ukusasazeka kwemitha kubhekiselele ekugqithisweni kobushushu ngamaza ombane.Nangona kunjalo, iibhotile ze-thermos zinciphisa ilahleko yobushushu obutshisayo ngokusebenzisa iingubo ezikhanyayo.Ezi zambatho zibonisa ubushushu obukhazimlayo obubuyela kwiflaski, bukhusela ukuba bungaphumi.
Ukongeza kwi-vacuum insulation, i-thermos nayo ixhotyiswe ngesivalo se-insulated.Isivalo sinciphisa ngakumbi ilahleko yobushushu ngokunciphisa utshintshiselwano oluthe ngqo lobushushu phakathi kolwelo kunye nomoya ongaphandle kweflaski.Yenza umqobo owongezelelweyo, ukuqinisekisa ukuba isiselo sakho sihlala kubushushu obufunekayo ixesha elide.
Ukwazi ukuba i-thermos ibuchitha njani ubushushu kusinceda ukuba siyixabise inzululwazi kunye nobunjineli obubandakanyekayo ekudaleni inkqubo enkulu yokugquma.Usebenzisa indibaniselwano yokuqhuba, ukuguquguquka, ukusasazeka kwemitha kunye nezivalo ezigqunyiweyo, ezi flasks zigqwesile ekugcineni ubushushu obufunekayo kwisiselo sakho, nokuba kushushu okanye kuyabanda.Ke kwixesha elizayo xa uphunga ikomityi eshushu yekofu okanye ukonwabela isiselo esibandayo seyure emva kokuzalisa i-thermos yakho, khumbula isayensi yokugcina ubushushu obufanelekileyo.
