ta yaya gyale flask ke rage convection da radiation

kwalabe na Thermos, wanda kuma aka sani da vacuum flasks, babban kayan aiki ne don kiyaye abubuwan sha masu zafi ko sanyi na wani lokaci mai tsawo.Bugu da ƙari, dacewa, thermos yana alfahari da ingantaccen tsarin rufewa wanda ke rage zafin zafi ta hanyar gudanarwa, convection, da radiation.A cikin wannan labarin, zamu bincika yadda thermos ke cimma wannan nasarar.

1. Rage gudanarwa:

Gudanarwa shine canja wurin zafi ta hanyar hulɗa kai tsaye tsakanin kayan biyu.Domin rage yawan sarrafawa a cikin kwalbar injin, kwalbar injin tana da tsari mai nau'i biyu wanda aka yi da ƙananan kayan aikin zafi.Yawanci, ana ƙirƙira wani wuri tsakanin bangon bakin karfe biyu.Bakin karfe zabi ne mai kyau saboda yana hana zafi daga sauƙin gudanar da shi ta saman sa.Wurin datti yana aiki azaman insulator, yana kawar da duk wani matsakaici wanda canjin zafi zai iya faruwa.

2. Rage convection:

Convection shine canja wurin zafi ta motsin ruwa ko gas.Thermos yana hana convection ta hanyar kwashe sarari tsakanin bangon ciki da na waje, yana kawar da duk wani yuwuwar motsin iska ko ruwa.Ragewar iskar da ke cikin filas ɗin kuma yana hana ɗaukar zafi, wanda ke hana canja wurin zafi daga abin da ke cikin ruwa zuwa yanayin da ke kewaye da filastar.

3. Hana radiation:

Radiation shine canja wurin makamashin zafi ta hanyar igiyoyin lantarki.Wuraren ɓarke ​​​​da kyau suna rage zafin zafi ta hanyoyi daban-daban.Na farko, sararin ciki mai haske na flask yana rage zafin rana ta hanyar nuna zafi a baya cikin ruwa.Wannan layin mai sheki kuma yana ba da kyakkyawan ƙarewa wanda ke rage fitar da zafi.

Bugu da ƙari, da yawa daga cikin filayen thermos suna nuna wani Layer na gilashin azurfa ko ƙarfe tsakanin bangon ciki da na waje.Wannan Layer yana ƙara rage radiation ta hanyar nuna duk wani zafi mai zafi ya koma cikin ruwa, don haka yana kiyaye zafinsa na tsawon lokaci.

A ƙarshe, filayen thermos suna rage canja wurin zafi ta hanyar gudanarwa, ɗaukar hoto da radiation ta hanyar ƙirar ƙira da haɗin kayan.Gine-gine mai bango biyu yawanci ana yin shi da bakin karfe, wanda ke rage tafiyar da aiki ta hanyar ƙarancin wutar lantarki.Ƙaƙwalwar ƙura tana cire duk wani matsakaici ta hanyar da canjin zafi zai iya faruwa, yana aiki azaman insulator mai kyau.Ta hanyar fitar da sararin samaniya tsakanin ganuwar, thermos yana hana convection daga kafa kuma, ta hanyar wannan tsari, yana hana canja wurin zafi.Bugu da ƙari, rufin da ke haskakawa da yaduddukan gilashin azurfa suna rage zafin zafi yadda ya kamata ta hanyar nuna zafi a baya cikin ruwa.

Duk waɗannan injiniyoyi suna haɗuwa don samar da ma'aunin zafi da sanyio don kiyaye yanayin da ake buƙata na abubuwan sha, zafi ko sanyi, na tsawon lokaci.Ko kuna jin daɗin kofi mai zafi yayin tafiya cikin hunturu, ko shan kopin ruwan sanyi a lokacin rani mai zafi, kwalabe na thermos abokan zama dole ne.

Gabaɗaya, ƙayyadaddun ƙirar thermos da hankali ga daki-daki suna ba da mafita mai ban sha'awa don rage canjin zafi ta hanyar gudanarwa, convection da radiation.Yi bankwana da abubuwan sha masu dumi kuma ku ji daɗin abin da kuka fi so na tsawon sa'o'i a ƙarshen madaidaicin zafin jiki.
