<\/p>\nModern termos, 1892 y\u0131l\u0131nda \u0130ngiliz fizik\u00e7i Sir James Duval taraf\u0131ndan icat edildi. O zamanlar, gaz\u0131n s\u0131v\u0131la\u015ft\u0131r\u0131lmas\u0131 \u00fczerine bir ara\u015ft\u0131rma \u00e7al\u0131\u015fmas\u0131 y\u00fcr\u00fct\u00fcyordu. Gaz\u0131 d\u00fc\u015f\u00fck s\u0131cakl\u0131kta s\u0131v\u0131la\u015ft\u0131rmak i\u00e7in, \u00f6ncelikle gaz\u0131 d\u0131\u015f s\u0131cakl\u0131ktan yal\u0131tabilecek bir kap tasarlamas\u0131 gerekiyordu. Bu y\u00fczden cam teknisyeni olan Berg'den kendisi i\u00e7in \u00e7ift katmanl\u0131 bir cam kap \u00fcflemesini istedi. \u0130ki katman\u0131n i\u00e7 duvarlar\u0131 c\u0131va ile kapland\u0131 ve daha sonra iki katman aras\u0131ndaki hava vakum olu\u015fturmak i\u00e7in d\u0131\u015far\u0131 pompaland\u0131. Vakum \u015fi\u015fesi, i\u00e7indeki s\u0131v\u0131n\u0131n s\u0131cakl\u0131\u011f\u0131n\u0131, ister so\u011fuk ister s\u0131cak olsun, belirli bir s\u00fcre sabit tutabilir.<\/p>\n
Termos \u015fi\u015fesi ailede \u00e7o\u011funlukla s\u0131cak su yal\u0131t\u0131m\u0131 i\u00e7in kullan\u0131ld\u0131\u011f\u0131ndan, s\u0131cak su torbas\u0131 olarak da adland\u0131r\u0131l\u0131r. Termos \u015fi\u015fesinin yap\u0131s\u0131 karma\u015f\u0131k de\u011fildir. Ortada \u00e7ift katmanl\u0131 bir cam kavanoz bulunur. \u0130ki katman aras\u0131ndaki vakum vakum durumuna \u00e7ekilir ve g\u00fcm\u00fc\u015f veya al\u00fcminyumla kaplan\u0131r. Vakum durumu termal konveksiyonu \u00f6nleyebilir. Cam\u0131n kendisi k\u00f6t\u00fc bir \u0131s\u0131 iletkenidir. G\u00fcm\u00fc\u015f kaplamal\u0131 cam, kab\u0131n i\u00e7inden yay\u0131lan \u0131s\u0131y\u0131 geri yans\u0131tabilir. Tersine, \u015fi\u015fede so\u011fuk s\u0131v\u0131lar saklan\u0131rsa, \u015fi\u015fe \u0131s\u0131n\u0131n d\u0131\u015far\u0131dan \u015fi\u015feye yay\u0131lmas\u0131n\u0131 \u00f6nleyebilir.<\/p>\n

Termos \u015fi\u015fesinin mantar\u0131 genellikle mantardan veya plastikten yap\u0131l\u0131r ve bu iki malzeme de \u0131s\u0131y\u0131 iletmek i\u00e7in kolay de\u011fildir. Termos \u015fi\u015fesinin kabu\u011fu bambu \u00f6rg\u00fcl\u00fc, plastik, demir, al\u00fcminyum, paslanmaz \u00e7elik ve di\u011fer malzemelerden yap\u0131l\u0131r. \u015ei\u015fenin a\u011fz\u0131nda kau\u00e7uk bir rondela ve \u015fi\u015fenin alt k\u0131sm\u0131nda kase \u015feklinde kau\u00e7uk bir yast\u0131k bulunur. Bunlar\u0131n hepsi cam safra kesesinin d\u0131\u015f kabukla \u00e7arp\u0131\u015fmas\u0131n\u0131 \u00f6nlemek i\u00e7in sabitlemek i\u00e7indir.<\/p>\n
Termos \u015fi\u015fesinin en k\u00f6t\u00fc \u0131s\u0131 koruma ve so\u011futma i\u015flevi dar bo\u011faz \u00e7evresindedir. Bu nedenle, \u00fcretim s\u0131ras\u0131nda dar bo\u011faz her zaman m\u00fcmk\u00fcn oldu\u011funca k\u0131salt\u0131l\u0131r. Termos \u015fi\u015fesinin kapasitesi ne kadar b\u00fcy\u00fck ve a\u011fz\u0131 ne kadar k\u00fc\u00e7\u00fckse, \u0131s\u0131 koruma etkisi o kadar iyidir.<\/p>\n

Insulation principle of vacuum flask The modern thermos flask was invented by British physicist Sir James Duval in 1892. At that time, he was conducting a research work on liquefying gas. To liquefy gas at low temperature, he first needed to design a container which could insulate the gas from the outside temperature.
