Problems solved by technology

The thermal efficiency of the Peltier element is therefore small relative to other known cooling mechanisms
Furthermore, it may itself require more installation space than the electronic components to be cooled themselves
Furthermore, Peltier elements are relatively expensive, and thus are not usually considered for their wide application

Abstract

The invention relates to a method and to a device for conveying at least one heat-exchange medium (2,66) which has at least one first fluid (3,4,5), which has a first permittivity, and at least one second fluid (3,4,5), which does not mix with the first fluid (3,4,5) and has a second permittivity which differs from the first permittivity, wherein at least one dielectric interface (16) is formed between the first and second fluids (3,4,5), which dielectric interface (16) is subjected to an electrical thrust field (19) which is excited in a progressing fashion and which exerts a thrust (27') on the at least one dielectric interface (16).

Description

technical field [0001] The invention relates to devices and methods for conveying fluid media. Background technique [0002] For cooling electrical, electronic or micromechanical components and integrated circuits, convective flow of fluids in liquid or gaseous form driven by means of turbo pumps or displacement pumps is common. The circulating fluid absorbs heat on the hot, small surface of the component to be cooled by means of thermal diffusion and transfers the heat to a heat exchanger with a larger surface in the form of thin plates or fins on the surface of the system , usually a good thermal conductivity to the enclosure of the component. The media flow on the outer surface creates a favorable effect which counteracts the boundary effects which would negatively affect the heat transfer. [0003] In contrast to passive heat transfer by thermal diffusion, driven (forced) coolant circulation by means of pumps or blowers entails increased construction costs. Furthermor...
