Lattice Structures for Heat Exchangers

Solitaire Overseas is the highly acclaimed industry that globally is dealing as a stockist & supplier of the high quality of ST52 Grade Seamless pipe as a Manufacturer we are fully involved in making the high product for the Metal Market.

Self-supporting behaviour is the most desired characteristic for DFAM of cellular structures. In the present work, gyroid, star kagome and BCC cellular structures are evaluated for self-supporting behaviour using Materialise Magics software. 

A micro-scale cross-flow heat exchanger is constructed from a hollow nickel microlattice structure, which is fabricated by conformally electroplating nickel onto a sacrificial polymer micro-lattice formed from self-propagating photopolymer waveguides.

Additive manufacturing has added a new dimension to manufacturing technology. The Design for Additive Manufacturing (DFAM) principles provide guidelines for successful 3D printing. Several industrial applications utilise he cellular structures in AM for design improvement by light weighting, topology optimization, etc.
