Wakambozvibvunza here kuti chinwiwa chako chinopisa chicharamba chichidziya kwemaawa akawanda sei, kunyange mumazuva echando anotonhora zvikuru kana pakufamba kwenguva refu?Mhinduro iri mune inoshamisa tekinoroji kuseri kwe thermos (inozivikanwawo se thermos).Kutenda kune yakasarudzika dhizaini uye kuvharirwa kwakasimba, iyi yehungwaru yekugadzira inochengeta zvinwiwa zvako zvichipisa kana kutonhora kwenguva refu.Mune ino blog, isu tichaongorora inonakidza sainzi kuseri kwekuti thermoses inodzivirira sei kurasikirwa nekupisa.
Nzwisisa pfungwa ye thermos:
Pakutanga kuona, thermos inoratidzika sechigadziko chakareruka chine screw top.Zvisinei, kushanda kwayo pakuchengetedza kudziya kwezviri mukati kunobva pakuti inovakwa sei.Thermos inoumbwa nezvikamu zvikuru zviviri: deko rekunze negaba remukati, rinowanzogadzirwa negirazi, simbi isina tsvina, kana plastiki.Izvo zvikamu zviviri zvakapatsanurwa neavacuum layer inogadzira chivharo chekupisa chinoderedza kutamisa kupisa.
Kudzivirira conduction:
Imwe yenzira iyo thermoses inodzivirira kurasikirwa nekupisa ndeye kuderedza conduction.Conduction (Conduction in English) inzira iyo kupisa kunofambiswa kubva pane chimwe chinhu kuenda kune chimwe kana zviro zvasangana.Mu thermos, girazi remukati kana chigadziko chesimbi (chinobata mvura) chakakomberedzwa nevhavha, kubvisa chero kushamwaridzana kwakananga nekunze kwekunze.Kushaikwa kwekubatana uku kunodzivirira kufambiswa kwekupisa ne conduction, nekudaro kuchengetedza tembiricha inodiwa mukati meflask.
Bvisa convection:
Convection, imwe nzira yekupisa kupisa, zvakare yakaderedzwa zvakanyanya mu thermos.Convection inoitika kuburikidza nekufamba kwezvimedu zvinodziya mukati memvura kana gasi.Nekugadzira vacuum layer, flask inodzvanya kufamba kwezvimedu izvi, nekudaro ichideredza mukana wekurasikirwa nekupisa kuburikidza neconvection.Izvi zvinovimbisa kuti tembiricha yemvura inopisa muflask inoramba yakagadzikana kwenguva yakareba, kudzivirira kutonhora nekukurumidza kwemvura inopisa muflask.
Reflected Radiant Heat:
Radiation ndiyo nzira yechitatu yekupisa kupisa, inotariswa neanoratidzira zvinhu zve thermos.Radiative kupisa kurasikirwa kunoitika kana chinhu chinopisa chinoburitsa mwaranzi inopisa, ichiendesa simba kuchinhu chinotonhorera.Thermoses inoratidzira nzvimbo inopenya kana machira, senge sirivheri kana aruminiyamu, kuderedza kutapurirana kwemwaranzi.Aya matinji anopenya anoratidza kupisa kunopenya, achiichengeta mukati memudziyo wemukati uye kuderedza kurasikirwa kwekupisa.
Enhanced insulation ine mamwe ma layer:
Mamwe ma thermoses anosanganisira yekuwedzera insulation kuti ipe imwe dziviriro kubva pakurasikirwa nekupisa.Aya maturu anowanzo gadzirwa nefuro kana zvimwe zvinhu zvinodzivirira uye anobatsira kuwedzera kugona kwekudzivirira kweflask.Nekuwedzera aya mamwe maseru, iyo thermos inogona kugara ichipisa kwenguva yakareba, ichiita kuti ive shamwari yakanaka yekushanya kwekunze kana kufamba kwenguva refu.
Iyo thermos yemazuva ano inoshamisa yesainzi, yakagadzirirwa kuchengetedza zvinwiwa zvako zvaunofarira zvichipisa kuti ugone kunakidzwa nazvo chero nguva, chero kupi.Kuburikidza nemusanganiswa wetekinoroji yekudzikisa conductive, convective uye inopenya kupisa kwekufambisa uye kuwedzera insulation, iyo thermos inoderedza kurasikirwa kwekupisa kuitira kuti unakirwe nechinwiwa chako chinopisa nekumhanya kwako wega.Saka nguva inotevera yaunotora sip kubva muflask uye uchinzwa kudziya kunonyaradza, tenda sainzi yakaoma iri kushanda muchinhu ichi chinonyengera chemazuva ese.
