sei vacuum flask inoshaya kupisa

Mabhodhoro eThermos, anonyanya kuzivikanwa sekuti vacuum flasks, ave chinhu chaunofanira kuva nacho kune vakawanda.Zvinotibvumira kuchengeta zvinwiwa zvedu zvatinofarira zvichipisa kana kutonhora kwenguva yakareba, zvichiita kuti zvive zvakanaka kune nzendo refu, mafambiro ekunze kana kungonakidzwa nechinwiwa chinopisa pazuva rinotonhora rechando.Asi wakambozvibvunza here kuti thermos inokwanisa sei kuchengetedza zviri mukati mayo patembiricha inodzorwa kwenguva yakareba?Mune ino blog, isu tichaongorora mune sainzi seri kwekurasikirwa nekupisa kubva kune thermoses uye tidzidze kuti nei ichinyatso shanda pakuisa insulating.

Dzidza nezve kupisa kupisa:
Kuti unzwisise kuti vacuum flask inobvisa sei kupisa, zvakakosha kuti unzwisise pfungwa yekupisa kupisa.Kupisa kunoramba kuchitamiswa kubva kunzvimbo dzetembiricha yakakwira kuenda kunzvimbo dzetembiricha yakaderera kuitira kuti uwane kuenzana kwekupisa.Pane nzira nhatu dzekutamisa kupisa: conduction, convection uye radiation.

Kufambisa uye convection mu thermos:
Thermoses inonyanya kuvimba nenzira mbiri dzekupisa kupisa: conduction uye convection.Aya maitiro anoitika pakati pezviri mukati meflask uye mukati nekunze madziro eflask.

conduction:
Kufambisa (conduction) zvinoreva kufambiswa kwekupisa kuburikidza nekusangana kwakananga pakati pezvinhu zviviri.Mu thermos, iyo yemukati-kati inobata mvura inowanzogadzirwa negirazi kana simbi isina tsvina.Zvese zviri zviviri izvi zvigadziriso zvisina kunaka zvekupisa, zvinoreva kuti hazvibvumire kupisa kuyerera kuburikidza nazvo.Izvi zvinoderedza kuendeswa kwekupisa kubva kune zviri mukati meflask kuenda kune kunze kwekunze.

convection:
Convection inosanganisira kutamisa kupisa kuburikidza nekufamba kwemvura kana gasi.Mune thermos, izvi zvinoitika pakati pemvura uye mukati memadziro eflask.Mukati meflask kazhinji ine magirazi maviri madziro, nzvimbo iri pakati pegirazi madziro iri kuita zvishoma kana kubviswa zvachose.Iyi nharaunda inoshanda se insulator, inorambidza kufamba kwemamorekuru emhepo uye kuderedza iyo convective process.Izvi zvinobudirira kuderedza kupisa kwekupisa kubva mumvura kusvika kumhepo yakapoteredza.

Radiation uye insulating caps:
Kunyangwe conduction uye convection iri nzira yekutanga yekurasikirwa nekupisa mu thermos, radiation inoitawo basa diki.Radiation inoreva kutamiswa kwekupisa nemasaisai emagetsi.Nekudaro, mabhodhoro e thermos anoderedza kupisa kwekupisa kurasikirwa nekushandisa anopenya machira.Aya machira anoratidza kupisa kunopenya kudzoserwa muflask, zvichidzivirira kutiza.

Mukuwedzera kune vacuum insulation, iyo thermos inoshongedzerwa nevhavha yakavharidzirwa.Iyo chivharo inowedzera kuderedza kurasikirwa nekupisa nekudzikisira kusangana kwakananga kupisa kuchinjanisa pakati pemvura nemhepo iri kunze kweflask.Inogadzira imwe chipingamupinyi, kuve nechokwadi chekuti chinwiwa chako chinogara pane tembiricha yaunoda kwenguva yakareba.

Kuziva kuti thermos inobvisa sei kupisa kunotibatsira kukoshesa sainzi nehuinjiniya inobatanidzwa mukugadzira yakakura kudaro yekuvharisa system.Uchishandisa musanganiswa we conduction, convection, radiation uye insulated lids, maflask aya akanaka pakuchengeta tembiricha yaunoda chinwiwa, kungave kuchipisa kana kutonhora.Saka nguva inotevera paunenge uchinwa kapu inopisa yekofi kana kunakidzwa nechinwiwa chinotonhorera chinotonhorera maawa mushure mekuzadza thermos yako, rangarira sainzi yekuchengeta tembiricha yakakwana.
