Embodiment Construction

[0014] According to the present invention there is provided a method of providing an article having a set of directional channels, as described in the appended claims. Articles, such as heat exchangers, having a set of directional channels are also provided. Other features of the invention will be apparent from the dependent claims and the following description.

[0015] method

[0016] A first aspect provides a method of providing an article having a set of directional channels including a first directional channel, the method comprising:

[0017] preparing a mixture comprising a first binding agent and particles comprising a first material;

[0018] providing a precursor to an article by surrounding a pattern comprising a second material with said mixture;

[0019] heating the article precursor to coalesce the particles to provide the article; and

[0020] The pattern is removed by reacting the second material to form a gaseous product, thereby providing the set of direc...

Abstract

A method of providing an article having a set of directional channels, including a first directional channel, therein is described. The method comprises preparing a mixture including particles comprising a first material and a first binding agent. The method comprises providing an article precursor by surrounding a pattern comprising a second material with the mixture. The method comprises heatingthe article precursor thereby coalescing the particles to provide the article. The method comprises removing the pattern by reacting the second material to form a gaseous product, thereby providing the set of directional channels in the article, wherein the set of directional channels corresponds with the removed pattern. Such an article is also described.

Description

technical field [0001] The present invention relates to an article and a method of providing the article, and more particularly to an article having a set of directional channels including a first directional channel. Background technique [0002] Porous metals, also known as metal foams or honeycomb metals, have a variety of applications including thermal management, energy absorption, catalyst supports and lightweight structures. In particular, open-pore porous metals are useful in heat exchangers and porous electrodes, such as in batteries and wastewater treatment, because of their high internal surface area and good fluid permeability. Open porous copper with oriented channels (also known as oriented pores) therein is an open porous metal with a variety of applications including thermal management, especially heat transfer and / or cooling. In particular, the directional channels have relatively low resistance to fluid flow along their direction (i.e., along the direction...
