Re fokotsa sebaka ho tloha ho boiler ho ea ho radiator (re khutsufatsa bolelele ba liphaephe) - re fumana setofo sa Serussia.
Joalokaha u ka be u nahanne, theknoloji e sebetsa ka mahlakore ka bobeli.
U ka e fokotsa ho fihlela ho zero kapa ua e eketsa ho isa ho tse sa feleng.
Ho fokotsa bolelele ba li-conductor tsa motlakase ho lebisitse ho thehoeng ha li-microcircuits.
Bolelele, bophahamo le bophara ke litekanyo tsa geometri. Litekanyo tsa lefatše la sebele (le bonahalang).
Litekanyo li ka ba tse hlakileng haholoanyane:

- Nako
- Boima ba 'mele
- Boima ba tsona
- Ho khanna ho chesang
- Motlakase conductivity
- Khotso
- Ho senyeha

Joang ho fokotsa conductivity ea mocheso ho zero?
Ho lokile.
Fokotsa palo ea liathomo, limolek'hule le lielektrone. Ke hore, etsa vacuum.
Theknoloji e tšoanang e se e ntse e le teng 'me e ntse e rekisoa. E bitsoa "screen vacuum thermal insulation". Liphanele tse nang le mocheso oa mocheso o lekanang le 0,004-0,006 W/m*K.
Ha ho bapisoa, sena se ka tlase ho makhetlo a 10 ho feta boea ba diminerale le makhetlo a 50 ho feta setene.
Ka lebaka leo, botenya ba marako bo ka fokotsoa ka makhetlo a mangata.
