Diody termiczne - potencjalne możliwości wykorzystania diod termicznych w technice

Fieducik J., Godlewski J.

Zeszyty Naukowe Politechniki Rzeszowskiej. Budownictwo i Inżynieria Środowiska

2012

z. 59, nr 2/II/I

W artykule przedstawiono zagadnienia przewodnictwa i przenikania ciepła w różnych strukturach. Przeanalizowano działanie różnych rodzajów makro, mikro i nano diod termicznych. Wskazano możliwości transportu ciepła przy pomocy diod w ściśle określonym kierunku, oraz możliwości wykorzystania tych rozwiązań w budownictwie.

The paper presents issues relating to conduction and heat transfer in different structures. The operation of different types of macro, micro and nano thermal diodes were analyzed. The potential of heat transport through diodes in a specific direction, and the possibility of using these solutions in construction were described.

New solutions of thermal diode with natural turbulent circulation

Bieliński H., Mikielewicz J.

Archives of Thermodynamics

The thermal diode allows heat to be transferred in one direction, preventing the transfer of heat in the opposite direction. Two new models of the thermal diode are presented in this paper. The first model describes the thermal diode heated simultaneously from below and symmetrically from the sides, while the second model demonstrates the thermal diode heated from a lower part of one side and cooled from the upper part of the opposite side. The analysis of fluid flow and heat transfer is based on a one-dimensional model. Distributions of temperature and mass flow rate are obtained for the steady-state turbulent flow. It is shown that the geometrical and thermal parameters have an influence on the steady-state flow rate.

The thermal diode allows the heat to be transferred in one direction, preventing the transfer of heat in the opposite direction. Two new models of the thermal diode are presented in this paper. The first model describes the thermal diode heated simultaneously from below and symmetrically from the sides, whilst the second model demonstrates the thermal diode heated from a lower part of one side and cooled from the upper part of the opposite side. The analysis of fluid flow and heat transfer is based on a one-demensional model. Distributions of temperature and mass flow rate are obtained for steady-state laminar flow. Numerical calculations are performed for the onset of motion of the fluid from rest. It is shown that the geometrical and thermal parameters have an influence on both the steady-state flow rate and the problem of global flow initiation from the rest.
