Methods, plate elements and heat/enthalpy exchangers, a) perforating an unformed plate element with defined outer dimensions in any desired area and in any desired dimension; b) covering at least one side of the unformed plate element with a thin polymer film with latent energy exchange characteristics and; c) forming the plate element into a desired shape and a pattern of corrugations and/or embossing. The operations b) and c) may be performed in a different order. For instance, when the plate element is made out of plastic, b) may be performed before c) whereas, when the plate element is made out of aluminum (or plastic), c) may be performed before b). Operations a) and/or b) and/or c) may also, in certain embodiments, be combined.

In a metal fiber composite (MFC) additive manufacturing (AM) method, a layer of polymer structures is deposited using a fused filament fabrication (FFF) printer assembly comprising at least one nozzle. Subsequently, an MFC printer assembly is used to embed a continuous metal fiber into one or more of the polymer structures of the layer. The embedding is achieved by heating the metal fiber and applying pressure to the metal fiber using an embedding surface of the MFC printer assembly. The heated metal fiber melts polymer adjacent thereto, thereby allowing the pressure to embed the metal fiber into the polymer structure. Using the MFC-AM method, various composite structures can be formed, such as novel heat exchangers that may otherwise be difficult or impossible to fabricate via other manufacturing techniques.

One aspect of this disclosure provides a heat exchanger that comprises a first panel half coupled to a corresponding second panel half that form a passageway having at least a first chamber adjacent an inlet end of the passageway and a second chamber and overlapping interference patterns formed in each of the first and second panel halves that extend along at least a portion of the length of the passageway and located between at least the first and second chambers.

The present invention discloses a preparation method for a hollow radiator and a hollow radiator. The preparation method comprises the following steps: 1) providing a feed and an insert raw material; 2) molding the insert raw material into an insert; 3) placing the insert in a cavity of a mold, and filling the cavity with the feed by injection molding in such a manner that the insert is surrounded by the feed, thereby obtaining a green body with the insert; 4) performing debinding treatment on the green body with the insert to remove the insert, thereby obtaining the green body of a hollow structure; and 5) sintering the green body to obtain the hollow radiator. By the preparation method for a hollow radiator according to the present invention, a radiator of a complex hollow structure can be fabricated, and the heat dissipation effect of the radiator can be improved. Moreover, the airtightness and leakproofness of the radiator can be guaranteed for a long time.

Flexible graphite and other graphite materials with surface micro-texturing, and methods and apparatuses for micro-texturing the surface of flexible graphite and other graphite materials are provided. Micro-texturing can be used to modify wettability and/or adhesion characteristics of a flexible graphite surface. Micro-textured flexible graphite materials can be advantageously used in applications where the material is in contact with liquid water or other liquids.

A method for additively manufacturing a microstructure from a caloric material includes providing a geometry of the microstructure to a processor of an additive manufacturing device, the geometry defining a plurality of microfeatures of the microstructure. The method also includes generating, via the processor, a three-dimensional (3D) model representative of the geometry of the microstructure, wherein one or more of the plurality of microfeatures are represented in the 3D model by a non-arcuate profile. Further, the method includes printing, via the additive manufacturing device, the microstructure from the caloric material according to the 3D model. As such, the non-arcuate profile reduces a file size of the 3D model as compared to an arcuate profile.
