Mathermo evacuumimhando yemakapu anozivikanwa. Chinangwa chayo ndechekubvisa nzira yekufambisa kupisa ye convective heat transfer uye contact heat transfer uye kuishandura kuita vacuum kuti iwane mhedzisiro yekuchengetedza kupisa. Nokudaro, mvura inodururwa mu vacuum thermos cup inogona kuchengetedza tembiricha yayo yepakutanga kwenguva yakareba. Muhupenyu, vamwe vanhu vanoshandisa vacuum mugs kugadzira kofi kana kuchengetedza mvura ichitonhora.
Bhodhoro rekudzivirira kupisa (vacuum insulation) rinowanzova mudziyo wemvura wakagadzirwa nesimbi isina ngura uye muchina wekudzivirira kupisa (vacuum layer). Rine chifukidziro pamusoro uye rakavharwa zvakasimba. Muchina wekudzivirira kupisa (vacuum insulation layer) unogona kunonoka kupisa kwemvura nezvimwe zvinwiwa zviri mukati, kuitira kuti pave nechinangwa chekuchengetedza kupisa.
1. Mutumbi webhodhoro rekuchengetedza kupisa une chimiro chakapetwa kaviri, uye vacuum yebhokisi repurasitiki nemuviri webhodhoro zvinogona kudzivirira kutapurirana kwekupisa.
Uyezve, kana kushanda kwesefa kwekapu yethermos kwakanaka, zvine basa rakakosha mukuita kwekudzivirira kupisa. Kana sefa iri nani, zvinova zvakaoma kutamisa kupisa, kuitira kuti mhedzisiro yekudzivirira kupisa ive nani.

2. Chigadziko chevacuum chesimbi isina ngura chine mativi maviri hachifambise kupisa, izvo zvakafanana nekucheka chinofambisa kupisa.
Kana vacuum drip yakakwira, zvinoita kuti insulation iwedzere. Tekinoroji yekupomba vacuum yakakamurwa kuita tail pumping uye tail pumping. Iye zvino vagadziri vazhinji vemakapu ethermos vanoshandisa tail pumping nekuti tekinoroji iyi yafambira mberi.
3. Tangi remukati rakaputirwa nemhangura kana sirivha. Tangi remukati rakaputirwa nemhangura kana sirivha, izvo zvinogona kugadzira jira rekudzivirira kupisa mutangi remukati mekapu yethermos.
Nenzira iyi, jira remhangura rinogona kuderedza kupisa kunorasika kuburikidza nemwaranzi nekuratidza mwaranzi yekupisa. Chirongo kana kapu kazhinji kacho mudziyo wakagadzirwa nesimbi isina ngura uye vacuum layer. Ine chifukidziro pamusoro uye yakavharwa zvakasimba. Vacuum insulation layer inogona kunonoka kupisa kwemvura nezvimwe zvinwiwa zvakaiswa mukati, kuitira kuti pave nechinangwa chekuchengetedza kupisa.
Izvo zvese zvinoenderana neruzivo rwakakodzera rwekapu ye thermos ye vacuum. Ndinotenda kuti vanhu vazhinji vachaziva kuti sei kapu ye thermos ye vacuum ine simba rakanaka rekudzivirira mushure mekuverenga chinyorwa chino pamusoro pekushandisa flask ye thermos ye vacuum uye musimboti we thermos ye vacuum. Kana muchizotenga thermos kana mamwe makapu nemabhodhoro, ndapota.taura nesuTiri nyanzvimugadziri wezvinwiwauye mutengesi we thermos cup muChina
