Demonstration of Aluminium-Beryllium Heat Exchangers Flat Panels with Embedded Fluid Networks

This paper presents « TEFNET » (Technology of Embedded Fluid Networks) a novel industrial approach in cooling and thermal management technique by manufacturing monolithic materials blanks with a dedicated embedded fluid network.

A high performance MMC (Metal Matrix Composite) AlBeMet-AM162 was used and material manufacturing was performed by HIP (Hot Isostatic Pressing) powder metallurgy surrounding special shaped removable kernels.

After kernel(s) removal by a dedicated chemical etching hollow 2D or 3D special shaped fluid networks, achievements such as small channels, serpentines, heat pipes or finned hollow core cold plates.... are realized.

Results and extensions of this technology are presented through examples.
