Porous Aluminum Innovative Heat Exchangers
Posted at: Offers to Sell and Export | Posted on: Wednesday 19 December 2012 3:05 pm | Poster last visit: Friday 10 May 2019 | Targeted Countries: UK | Belgium
Product Description:
Porous aluminum is an ideal material for being used as heat exchanger.
Aluminium has good thermal conductivity
and is the predominant material for heat transfer purposes. Because of the large internal surface area, porous aluminum has an even higher heat exchange capacity than conventionally fabricated aluminum.
Other porous materials such as sintered metals also havea big internal surface area. However, it is not yet possible to produce aluminum products with high volume porosity and sufficient strength by means of sintering technology (see our article „porous aluminum versus sintered metal“). A further advantage of porous aluminum is the cast structure which also fosters the thermal conductivity. Sintered metals also reveal thermal resistance at contact points between grains.
The thermal conductivity of porous aluminum has been tested at the Technical University of Freiberg. Depending on the pore size, the thermal conductivity of porous aluminum lies in the range 30 – 50 W/(m*K). Products made of porous aluminum are thus very well suited for being used as heat transfer elements.
Due to the high volume porosity, i.e. to the large inner surface, they are also suitable for being used as heat exchanger in the convective heat transfer. As water or other liquids, air or gas flow through the porous aluminum, it absorbs the temperature due to the large internal surface. This temperature can be transmitted to a solid body or fluid.
Porous aluminum is also excellent for cooling purposes. As the object to be cooled is attached directly to the porous aluminum, the heat is dissipated to the outside, if required with additional ventilation, by means of the large internal surface.
Products can be produced according to your needs in different shapes and sizes.
- Food-suitable
- Temperature resistant from -60°C to +400°C
- Very stable thanks to cast structure, pressure difference of up 25 bar
- Thermal conductivity 30 – 50 W/(m*K)
