Abstract:
L'invention porte sur un dispositif fluidique (1), comportant un boîtier (2) comprenant un canal (3) délimité par des parois, dont une première paroi principale (10), le canal (3) s'étendant entre deux orifices, dits d'entrée (4A) et de sortie (4B), et un milieu poreux à pores ouverts en un matériau métallique, dit mousse métallique (30), situé dans le canal (3) entre lesdits orifices d'entrée (4A) et de sortie (4B). La mousse métallique (30) et ladite première paroi principale (10) sont réalisées d'un seul tenant et en un même matériau, et la mousse métallique (30) présente une distribution spatiale aléatoire des pores.

Abstract:
Sugar alcohol blends of galactitol and mannitol and compositions comprising such blends are disclosed as phase change materials (PCMs). A method of forming carbon nanotubes on a carbon substrate is described. Carbon substrates with carbon nanotubes, in particular, conformal layers of carbon nanotubes on carbon substrates, are also disclosed, as are methods of making and using these materials. Thermal storage units are also provided. The thermal storage units can comprise a heat exchange path through which a heat exchange medium flows, and a thermal storage medium in thermal contact with the heat exchange path.
Abstract:
A heat sink for cooling a heat generating device comprises a body part with a first surface for contacting the heat generating device, and a second surface contacting a cooling part, and the cooling part including a cooling structure. The structure density of the cooling structure decreases with increasing distance to body part. The cooling structure may be a three dimensional structure e.g. a grid or a lattice, but the cooling structure may also be fins projecting or extending from the second surface of the body part. The heat sink can be manufactured using additive manufacturing e.g. selective laser melting process (SLM). The heat sink can be made of metals e.g. aluminum, copper, ceramics e.g. aluminium nitride (AIN), silicon carbide or a composite containing graphite, graphene or carbon nanotubes.
Abstract:
Flow profile with debossed boundaries of flow channels in the porous body with heart-exchange function consists of a plate (1), made of metal foam with open pore structure, where the flow channels are hydraulically defined by columns (2), created by pressing inert putty in the pores.
Abstract:
A heat exchange tube, a heat exchanger using such a tube and a method of making such a tube. Additive manufacturing is used to form at least a portion of the tube. Augmented heat exchange features, such as external and internal lattice structure may be built up along with the remainder of the tube to form an enhanced heat exchange region with intermittent, repeating shapes. Such shapes maximize heat-dissipating surface area of the tube while reducing or eliminating large external dimensions associated with traditional tube manufacture.
