Botolo lachitsulo chosapanga dzimbiri limataya kusungirako kutentha mwadzidzidzi, zomwe ziyenera kugwirizana ndi khalidwe la mankhwala;ngati ili mkati mwa alumali ya mankhwala, ikhoza kusinthidwa ndi wogulitsa panthawi yake.Chikho cha thermos chimapangidwa kuchokera ku botolo la thermos.Mfundo yotetezera kutentha ndi yofanana ndi ya botolo la thermos, koma anthu amapanga botolo kuti likhale kapu kuti zikhale zosavuta.
Njira yosavuta yozindikiritsira ntchito ya vacuum insulation:
(1) Thirani madzi otentha mu kapu ya thermos ndikumangitsa khomo lozungulira, kapena gwirani kunja kwa thupi la chikho ndi manja anu pakadutsa mphindi ziwiri kapena zitatu.Ngati kapu thupi mwachionekere kutentha, zikutanthauza kuti mankhwala wataya vacuum wake.Sangathe kukwaniritsa zabwino matenthedwe kutchinjiriza kwenikweni.Kunja kwa kapu yotsekeredwa kumakhala kozizira nthawi zonse.
(2) Onani ngati chidindo chamkati chili cholimba.Yang'anani ngati pulagi yowonongayo ndi thupi la kapu zikukwanira bwino, ngati chivindikiro cha kapu chikhoza kutsekedwa ndi kutuluka momasuka, komanso ngati madzi akutuluka.Dzazani madzi okwanira m'kapu ndikutembenuzira pansi kwa mphindi zinayi kapena zisanu kapena kugwedezani kangapo kuti muwonetsetse kuti palibe kutayikira.
Makapu osapanga dzimbiri a thermos amagawidwa kukhala: makapu wamba a thermos (nthawi yosungira kutentha nthawi zambiri imakhala yosakwana maola atatu mutathiridwa madzi otentha), makapu a vacuum thermos (kudzera mu vacuuming, madzi otentha amatha kutenthedwa nthawi zambiri kuposa). 8 maola).
1. Chifukwa chachikulu chomwe chikho cha thermos sichimatenthedwa ndi chakuti wosanjikiza wa vacuum pakati pa zipolopolo ziwirizo wawonongeka.M’katimo munali bwinja, koma tsopano muli mpweya.Chifukwa chake, chikho cha thermos chidzataya ntchito yosungira kutentha.
2. Mfundo ya botolo la vacuum ndi yofanana ndi ya thermos.Onse amagwiritsa ntchito chipolopolo chamagulu awiri, ndipo mpweya pakati pa zipolopolo ziwirizo umachotsedwa kuti ukhale malo opanda mpweya.Kuthekera kwa kutentha kwa vacuum ndikosauka kwambiri, kotero kuti The convection ndi conduction ya mphamvu yotentha zimachepetsedwa kwambiri.
3, kapu yabwino ya thermos, mwamwayi, chivindikiro cha chikho.Titha kunena kuti kutsekemera kwamafuta a kapu ya thermos kumatsimikiziridwa ndi magwiridwe antchito a kapu ya botolo.Makapu ambiri wamba a thermos amapukutidwa mkati mwa kapu, kuti ma radiation a infrared azitha kusinthidwa.Sungani mphamvu ya kutentha mkati mwa kapu momwe mungathere.
