De vacu\u00fcmfles werd uitgevonden door Sir James Dewar in 1892. Hij zette de ene fles in de andere en verbond deze bij de flessenhals. De opening tussen de twee flessen leegt gedeeltelijk lucht, waardoor een bijna vacu\u00fcm ontstaat, waardoor warmtegeleiding en convectie aanzienlijk worden verminderd.<\/span><\/p>\n<p><span>Thermosflessen kunnen dranken lang koud of warm houden en hebben vele toepassingen.<\/span><\/p>\n<p style=\"text-align: center\"><img decoding=\"async\" src=\"\/wp-content\/uploads\/2024\/09\/20210421165254acd1b56d104a4542b3b546ef307e52a5.jpg\"><\/p>\n<p><span>De structuur van de vacu\u00fcmfles is een dubbellaags vacu\u00fcm. In feite bestaat het uit twee containers. De opening tussen de twee containers leegt gedeeltelijk de lucht en vormt een gedeeltelijk vacu\u00fcm, waardoor warmtegeleiding of convectie wordt verminderd. De warmteoverdracht veroorzaakt door warmtestraling kan worden geminimaliseerd door verzilvering op het binnenoppervlak van de vacu\u00fcmfles. De warmtebehoudtijd van de vacu\u00fcmfles is over het algemeen 12 ~ 24 uur. De temperatuur van de vloeistof en de temperatuur van de externe omgeving hebben ook invloed op het warmtebehoudeffect van de vacu\u00fcmfles. <\/span><\/p>\n<p><span><br \/><\/span><\/p>\n<p><span>Thermosflessen zijn meestal gemaakt van metaal (roestvrij staal), borosilicaatglas, keramiek of kunststof en zijn er in vele stijlen en functies.&nbsp;<\/span>Zet de thermosfles niet in de koelkast of magnetron.
