Why 3D printing?
The use of 3D printing in the production of our heat exchangers gives us maximum design freedom and precision. This innovative approach allows us to create complex structures and optimised geometries that conventional manufacturing methods cannot achieve. This leads to a significant improvement in the performance and efficiency of our HPEx®.
Thermal engineering
Extensive numerical calculations of strength and heat transfer with complex CFD simulations were carried out to develop the HPEx®. Various geometries were tested experimentally on high-temperature test benches at the Institute of Thermodynamics in Hanover.
Additive manufacturing (3D printing) quickly explained
Laser Powder Bed Fusion (LPBF) is an additive manufacturing process in which metal powder is applied in layers and then selectively melted by a laser beam. The laser fuses the powder at the desired points according to the digital 3D model to create complex metallic components layer by layer.
