Drawn polymer fibers have internal channels running, at least partially, through the length of the fibers. These fibers may be configured to for use as thermal isolators that can thermally isolate material at the central core of the fiber from the outside environment. In such instances, the channels may be used as insulating channels and/or a heating or cooling fluid can be pumped through the channels to maintain the temperature of the material at the inner core. As another application, the fibers may be used as recuperative, regenerative, parallel-flow, counter-flow, cross-flow or condenser/evaporator heat exchangers. In this case, the channels may be used to direct fluid flow. The fiber may allow for the exchange of heat between fluids in the channels.

A flexible sealing tube is described that is adapted to be installed in and extend along a bore in the ground for use in a system for exchanging of energy with the ground. The flexible sealing tube has a first tube end to be installed at an inner part of said bore, and the flexible sealing tube is closed in the first tube end. The flexible sealing tube also has a first channel and a second channel extending in a longitudinal direction (L) of the flexible sealing tube, the first and second channels being in fluid connection with each other. The first and second channels are formed by the flexible sealing tube.

A solar heat exchanger for heating water which includes an array of tubes, an injection molded manifold there being connections between each tube in the array and the manifold which are over molded to seal the tubes to the manifold.

The disclosure relates to a header connected to or formed as a part of a heat exchanger. The heat exchanger has a heat exchanger body with a plurality of discrete channels for a first fluid and a plurality of discrete channels for a second fluid. The header has a first end having a round configuration and a second end being provided with a plurality of discrete channels. The header is provided with a plurality of dividers dividing one or more internal channels of the circular pipe into the plurality of discrete channels at the second end. At least some of the dividers extend from the second end to the first end and define a plurality of channel mouths at the first end. The disclosure also relates to a heat exchanger.

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.
