Abstract
A heating element comprises a main body having a three-dimensional matrix with an open structure including openings and internal voids, cavities and/or pores extending throughout the main body. The three-dimensional matrix is provided as a lattice having a repeating unit cell extending in three directions. The present heating element is adapted for maximised surface area so as to provide an effective and efficient thermal energy transfer medium.
Claims24
A heating element, comprising:
- a main body, the main body being a three-dimensional matrix having an open structure defining openings, voids and/or pores extending through the main body,
- wherein the three-dimensional matrix is provided as a lattice having a repeating unit cell to define at least part of the main body,
- wherein the main body comprises at least two unit cells positioned adjacent to each other in a first direction (d1), at least two unit cells positioned adjacent to each other in a second direction (d2), and at least two unit cells positioned adjacent to each other in a third direction (d3),
- wherein the first, second, and third directions are arranged at an angle to each other, and
- wherein the repeating unit cell has a cubic shape and the first, second, and third directions are arranged orthogonally.
