Kodi botolo la vacuum limapangitsa bwanji kuti zakumwa zizitentha kapena kuzizizira

M'dziko lomwe kuchita bwino komanso kuchita bwino ndikofunikira, mabotolo a thermos akhala chinthu chofunikira tsiku lililonse kwa ambiri.Zotengera zatsopanozi, zomwe zimadziwikanso kuti thermoses kapena makapu oyenda, zili ndi kuthekera kodabwitsa kosunga zakumwa zomwe timakonda kuti zizitentha kapena kuzizizira kwa nthawi yayitali.Koma kodi thermos imagwira ntchito bwanji?Tiyeni tilowe mu sayansi yochititsa chidwi yomwe ili ndi luso lapadera la abwenzi awa.

Kufotokozera mfundo

Kuti timvetse bwino ntchito zamkati za thermos, tiyenera kumvetsetsa zofunikira za kutentha kwa kutentha.Kusintha kutentha kumachitika m'njira zitatu: conduction, convection ndi radiation.Thermos amagwiritsa ntchito njira zonsezi kuti atsimikizire kutsekemera.

Choyamba, chipinda chamkati cha botolo nthawi zambiri chimapangidwa ndi magalasi awiri kapena zitsulo zosapanga dzimbiri.Kapangidwe kameneka kamachepetsa conduction, kuteteza kutentha kusuntha pakati pa madzi ndi chilengedwe chakunja.Malo pakati pa makoma awiriwa amachotsedwa, ndikupanga vacuum.Vacuum iyi ndi insulator yofunikira yolimbana ndi ma conduction ndi kusamutsa kutentha kwa convection.

Kuphatikiza apo, mkati mwa chidebecho chimakutidwa ndi zinthu zonyezimira, monga siliva kapena aluminiyamu.Chounikira chonyezimirachi chimachepetsa kutentha kwa kutentha chifukwa chimawonetsa mphamvu ya kutentha yomwe ikuyesera kuthawa.

Ntchito

Kuphatikiza kwa vacuum ndi zokutira zowunikira kumachepetsa kwambiri kutentha kwamadzi omwe ali mkati mwa botolo.Madzi otentha akathiridwa mu thermos, amakhalabe otentha chifukwa cha kusowa kwa mpweya kapena tinthu tating'ono tosamutsa kutentha, mogwira mtima kutentha mkati.Mosiyana ndi zimenezi, posunga zakumwa zoziziritsa kukhosi, thermos imalepheretsa kulowetsedwa kwa kutentha kuchokera kumadera ozungulira, potero kusunga kutentha komwe kumafunikira kwa nthawi yaitali.

Zowonjezera

Opanga nthawi zambiri amagwiritsa ntchito zotsekera zowonjezera kuti ziwongolere magwiridwe antchito a botolo.Ma flasks ena amatha kukhala ndi makoma akunja okhala ndi mkuwa, zomwe zimathandiza kuchepetsa kutentha kwakunja.Kuphatikiza apo, mabotolo amakono a thermos nthawi zambiri amakhala ndi zipewa kapena zotchingira zokhala ndi ma gaskets a silicone kuti apange chisindikizo cholimba.Izi zimalepheretsa kutentha kulikonse ndi convection ndikuwonetsetsa kuti zisatayike, zomwe zimapangitsa kuti botolo likhale losavuta komanso losavuta.

Ma thermose asintha momwe timakondera zakumwa zotentha kapena zozizira popita.Mwa kuphatikiza matekinoloje osiyanasiyana otchingira monga vacuum, zokutira zowunikira komanso kutsekereza kowonjezera, zida zochititsa chidwizi zimatha kupangitsa zakumwa zathu kukhala zotentha kapena kuzizira kwa maola ambiri, kuzipanga kukhala chida chofunikira kwambiri pa moyo wathu wamakono wothamanga.
