Thermos makapuchinhu chakakosha kune chero munhu anoda zvinwiwa zvinopisa, kubva kukofi kusvika kune tii.Asi wakambozvibvunza here kuti zvinogona sei kuchengeta chinwiwa chako chichidziya kwemaawa panguva pasina kushandisa magetsi kana zvimwe zvinhu zvekunze?Mhinduro iri musayenzi yekudzivirira.
Thermos ibhodhoro re thermos rakagadzirirwa kuchengetedza zvinwiwa zvako zvichipisa kana kutonhora kwenguva yakareba.Thermos inogadzirwa nezvikamu zviviri zvegirazi kana plastiki ine vacuum yakagadzirwa pakati pezvikamu.Nzvimbo iri pakati pezvikamu zviviri haina mhepo uye yakanaka kwazvo yekupisa insulator.
Paunodurura mvura inopisa mu thermos, simba rinopisa rinogadzirwa nemvura inotamirwa kumukati wemukati we thermos kuburikidza ne conduction.Asi sezvo pasina mweya muflask, kupisa hakugone kurasikirwa ne convection.Izvo zvakare hazvigone kupenya kubva kune yemukati layer, iyo ine inopenya coating iyo inobatsira kuratidza kupisa kumashure muchinwiwa.
Nokufamba kwenguva, mvura inopisa inotonhora pasi, asi iyo yekunze ye thermos inoramba iri pakamuri yekupisa.Izvi zvinodaro nekuti vacuum iri pakati pezvikamu zviviri zveflask inodzivirira kutamisa tembiricha kuenda kuchikamu chekunze chemukombe.Nekuda kweizvozvo, simba rekupisa rinogadzirwa rinochengetwa mukati memugi, kuchengetedza chinwiwa chako chinopisa chichidziya kwemaawa.
Saizvozvo, kana iwe ukadira chinwiwa chinotonhora mu thermos, thermos inodzivirira kutamiswa kwe ambient tembiricha kuchinwiwa.Iyo vacuum inobatsira kuchengetedza zvinwiwa zvichitonhora kuitira kuti unakirwe nezvinwiwa zvinotonhora kwemaawa.
Makapu eThermos anouya mune ese maumbirwo, saizi uye zvinhu, asi sainzi kuseri kwekuita kwavo kwakafanana.Dhizaini yemugi inosanganisa vacuum, inoratidzira coating, uye insulation yakagadzirirwa kupa yakanyanya kuvharisa.
Muchidimbu, iyo thermos cup inoshanda pamusimboti wevacuum insulation.Iyo vacuum inodzivirira kupisa kupisa kuburikidza nekufambisa, convection uye radiation, kuve nechokwadi chekuti zvinwiwa zvako zvinopisa zvinogara zvichipisa uye zvinwiwa zvinotonhora zvinogara zvichitonhorera.Saka nguva inotevera paunonakidzwa nekapu inopisa yekofi kubva mu thermos, tora nguva yekutenda sainzi kuseri kwekuita kwayo.
