Resumen:
Un equipo de investigación de una universidad eslovaca ha desarrollado una tecnología innovadora para definir la trayectoria de un medio líquido en un material poroso sin que afecte a la conductividad térmica del material. Los materiales porosos se utilizan a menudo en intercambiadores de calor gas a líquido para aumentar el contacto superficial con el medio gaseoso. La tecnología encuentra aplicación en intercambiadores de calor que utilizan materiales porosos basados en espuma de metal, por ejemplo, en ingeniería eléctrica, metalurgia o industria química. Se buscan socios con el fin de establecer acuerdos de financiación, fabricación o licencia.

Flow profile with debossed boundaries
Summary:
Research team from distinguished Slovak university offers an innovative technology for defining the path of a liquid medium in porous material without disrupting thermal conductivity of the material. The technology is applicable in large scale of heat exchangers using porous materials based on foamed metals, e.g. in electrical engineering, metallurgy or chemical industry. Partners are sought for financial agreement, manufacturing or license agreement.
Description:
Porous materials are currently often used in gas-to-liquid heat exchangers in order to maximize surface contact with the gaseous medium. Following conditions must be satisfied in order to achieve the best possible distribution of liquid medium:
· Maximum contact with the surface of a porous material based on the foamed metal
· Minimal effect on the thermal conductivity allowing fluent heat transfer
These conditions are satisfied by presented technology, which defines the path of a liquid medium by pressing inert putty into the porous structure of thermally conductive material based on foamed metal. Flow profile with debossed boundaries of flow channels in a porous body with heat exchange function consists of a plate made from metal foam with an open pore structure, in which the flow channels are hydraulically defined by columns formed by inert putty debossed in the pores. The putty can be applied either using an application gun or using a template. Colum width depends on the size of the application hole through which the putty was applied and on the resistance of the metal foam structure to permeation of the putty in its pores.

The invention finds application in wide range of heat exchangers using porous materials based on foamed metals, ranging from micro applications in electrical engineering (e.g. cooling of microprocessors) to large-scale applications in manufacturing plants (metallurgy, mechanical engineering, chemical engineering and other). The technology enables creating multi-layered battery heat exchangers and allows the flow of the liquid medium in the three dimensions of the thermally conductive material. The application of the technology is simple and possible in various ways depending on the parameters and serializability of the product. The flow profile with debossed boundaries can also be used in solar thermal technology as the basic functional unit of a directly insulated full flow absorber of a solar collector based on metal foam.

The university is looking for industrial partners to cooperate with via financial agreement, manufacturing or licensing agreement. Specification of the cooperation offer:
· Financial agreement - university is looking for investors to the technology,
· Manufacturing agreement - transfer of knowledge in new raw materials,
· Licence agreement - a transfer of rights concerning the technology.
Advantages and Innovations:
The porous materials based on foamed metals with good thermal conductivity are being used in heat exchangers for some time. However, applications require in most cases channels or tubes for conducting the liquid medium, which are made of a different material and thus limit the heat transfer between the fluid and the material. The presented solution utilizes the porosity of the material and creates channels in thermally conductive material without restricting the fluid contact with the material and without interrupting thermal conductivity, which significantly increases the efficiency of the use of the material in heat exchangers. The columns representing the boundaries of the flow channels can at the same time serve to seal the contact surfaces between the metal foam plate and the partition plate. Another advantage is that the application of columns is a simple process that can be carried out under standard operating conditions without any requirements for special equipment. Also, the flow profile with debossed boundaries can be routed through the metal foam plate in any direction, enabling any design of blinding, crossing or discontinued path.
