The challenge was to uniformly dissipate a significant amount of heat in such a small space. The resulting aluminium micromachined, liquid cooled plate showed a reduction of 23% in size, 20% in weight and 18% in cost.
The liquid cold plates can be engineered to perform with diverse coolants, including water, water/glycol solutions, dielectric fluids, oils and synthetic hydrocarbons (PAO).
Baknor is also developing complex solutions that include advanced materials such as graphene films for very small, very limited space and lower power dissipation, as well as very thin extrusion plates that use phase change cooling. The graphene plate integrates graphene (5300 W/m·K) with diamond particles (2300 W/m·K) into a reticular structure, allowing thermal conduction without any interruption, while filling the holes of the structure mesh with carbon nNanocapsules (with a thermal radiation divergence of 0.98) to increase the thermal radiation efficiency.
