Design Engineering

HiETA offers design engineering services to a variety of industries and has demonstrated that we can engineer solutions for highly demanding applications. With extensive experience in understanding the principles of design for additive processes our engineering team also has expertise in thermo-fluids, structural analysis, 1D component and system modelling, 3D design, and perhaps most importantly, design for validation. Furthermore, with its comprehensive software toolbox, we prepare data for AM production, including file slicing repair, and support design.

Areas of specialism include:

Thermal management – with heat transfer and pressure drop requirements as the focus of product specifications, we are capable of reviewing complex thermal management problems and, alongside customers, developing novel, more cost-effective and efficient solutions. Most notably we have developed a range of high-performance heat transfer surfaces that exploit the shape freedom offered by Additive Manufacturing. These proprietary surfaces can reduce core volume and mass by 40% or more.

Light-weighting – AM processes provide opportunities for optimising component topology. In particular, they allow the design and manufacture of conventional and innovative lattice structures that are integrated into AM components. Such lattices or honeycomb structures can combine both load bearing and light-weighting functions. HiETA has gained considerable experience of their performance in a wide range of development projects.

Component integration – a further advantage of AM is that it allows the integration in single AM builds of two or more components that are normally manufactured separately. Advantages include reduced part-count and materials use, reductions in tooling and associated costs, reductions in final sub-system size, weight and costs and higher efficiency.

Novel functionality – product functionality can be improved by designing multi-functions into previously single-function components. For example, support structures, often in the form of lattices noted above can, in heat exchangers, be designed to have additional heat transfer or fluid control functions that again reduce the size, weight, and costs, and increase efficiency.
