Munyika yanhasi inomhanya-mhanya, tinovimba nematurusi akasiyana siyana uye majejeti kuita kuti hupenyu hwedu hwemazuva ese huve nyore.Imwe tsvarakadenga yakadaro yaive vacuum flask, inozivikanwawo sevhacuum flask.Chigaba ichi chinotakurika uye chinoshanda chashandura nzira yatinochengeta nekutakura zvinwiwa zvinopisa kana zvinotonhora, zvichizvichengeta patembiricha yaidiwa kwenguva yakareba.Asi wakambozvibvunza here kuti thermos inoshanda sei mashiripiti ayo?Mune ino blog post, isu tinonyura mune inonakidza nyika ye thermos tekinoroji uye kuongorora kuti ingaite sei kuderedza kupisa kurasikirwa.
Pfungwa yekupisa kupisa:
Usati wanyura mune zvakadzama zve thermos flasks, zvinodikanwa kuti unzwisise iyo yakakosha pfungwa yekupisa kupisa.Kutamisa kupisa kunogona kuitika kuburikidza nenzira nhatu dzakasiyana: conduction, convection, uye radiation.Kufambisa ndiko kutamisa kupisa kuburikidza nekusangana kwakananga pakati pezvinhu zviviri apo convection iri kutamisa kupisa kuburikidza nekufamba kwemvura yakaita semhepo kana mvura.Radiation inosanganisira kutamiswa kwekupisa muchimiro chemagetsi emagetsi.
Kunzwisisa Kurasika Kwekupisa mumidziyo Yechinyakare:
Midziyo yechinyakare, senge mabhodhoro kana makogi, kazhinji haigone kuchengetedza tembiricha yaunoda yemvura mukati kwenguva yakareba.Izvi zvinonyanya kukonzerwa nekurasikirwa kwekupisa kunofambiswa nekuita uye convection maitiro.Kana mvura inopisa inodururwa mubhodhoro rakajairika, kupisa kunoitwa nekukurumidza kune kunze kwechigadziko, uko kunorasirwa mumhepo yakapoteredza.Mukuwedzera, convection mukati memudziyo inokurumidza kutengesa kupisa, zvichiita kuti kurasikirwa kukuru kwesimba rinopisa.
Nheyo yebhodhoro rethermos:
Iyo thermos yakagadzirwa nehungwaru kudzikisa kurasikirwa nekupisa nekubatanidza akati wandei maficha.Chinhu chakakosha chinoisa iyo thermos parutivi ndeyekuvakwa kwayo kwakapetwa kaviri.Madziro emukati nekunze anowanzo kugadzirwa nesimbi isina tsvina uye akaparadzaniswa nevhavha.Iyi vacuum layer inoshanda sechidziviriro chinoshanda chekupisa, chinotadzisa kupisa kufambiswa ne conduction uye convection.
Inoderedza conductive kupisa kwekufambisa:
Iyo vacuum layer muflask inobvisa kusangana kwakananga pakati pemadziro emukati nekunze, zvakanyanya kuderedza kupisa kupisa.Iko hakuna mweya kana nyaya muvacuum, uye kushomeka kwezvimedu zvinogona kutamisa kupisa kunovimbisa kushoma kurasikirwa kwesimba rekupisa.Iyi nheyo inochengetedza zvinwiwa zvinopisa zvichidziya kwemaawa, zvichiita kuti thermoses ive yakanaka kune zviitiko zvekunze, kufamba kwenguva refu kana kunyange manheru anotonhorera kumba.
Dzivirira convective heat transfer:
Kuvakwa kwevacuum flask kunotadzisawo convection iyo inokonzera kukurumidza kupisa kupisa.Iyo insulating vacuum layer inodzivirira mweya kubva kutenderera pakati pemadziro, ichibvisa convection senzira yekurasikirwa nekupisa.Iyi mhinduro yekuvandudza inowedzera kuchengetedza tembiricha yaunoda kwenguva yakareba, ichiita iyo thermos sarudzo yakanaka yekunakirwa nezvinwiwa zvinopisa pakufamba.
Kuvhara Chibvumirano: Zvimwe Zvimiro:
Pamusoro pekuvakwa kwemadziro maviri, mabhodhoro e thermos anowanzo aine mamwe maficha kuti ave nechokwadi chekushanda kwakanyanya.Izvi zvinogona kusanganisira airtight silicone seals kana rubber plugs inodzivirira kurasikirwa nekupisa kuburikidza nekuvhura.Pamusoro pezvo, mamwe maflask ane machira anovhenekera mukati memukati kuti aderedze kupisa kunopisa.
mukupedzisa:
Iyo thermos chiratidzo chehungwaru hwevanhu uye chishuvo chedu chisingaperi chekugadzira mhinduro dzinoshanda kumatambudziko ezuva nezuva.Nekushandisa misimboti ye thermodynamics, chigadzirwa chakareruka ichi asi chakajeka zvinoderedza kurasikirwa nekupisa uye kuchengetedza zvinwiwa zvedu patembiricha yakakwana kwenguva yakareba.Saka kunyangwe urikunwa kapu inopisa yekofi mangwanani anotonhora kana kunakidzwa nekapu inozorodza yetii pazuva rinopisa rezhizha, unogona kuvimba nethermos yako kuchengetedza chinwiwa chako sezvaunoda - chinwiwa chinopisa chinogutsa kana inozorodza inotonhorera.
