Nilay Parikh Global Project Manager – Additive Manufacturing with Danfoss Nilay Parikh works in the position of Global Project Manager – Additive Manufacturing with Danfoss, where he is in-charge of setting up the internal Danfoss Additive Design and Manufacturing (ADM) Competency Centers in Europe, US and Asia. Having successfully set the Danfoss European ADM Center at the HQ in Denmark, he recently moved back to the United States to start the implementation of the North American AM Center. Nilay is also in-charge of training and development of the Danfoss workforce in AM and evangelizing of Additive and Digital Manufacturing methodologies across Danfoss globally.

Having attained Masters in Mechanical Engineering from the University of Southern California (USC), Los Angeles, Nilay has worked as Project Facilitator and Consultant with a premier Additive Manufacturing service provider in the Southern California area before joining Danfoss. As a Masters student, Nilay had the chance to work on researching the prospects of 4D printing in the CRAFT (Center for Rapid Automated Fabrication Technologies Lab) at USC.

Stefan Gronau Dipl.-Ing. (FH), Research and Development Engineer, Laserinstitut Hochschule Mittweida (LHM), Germany Stefan Gronau is an Research and Development Engineer on the Laserinstitut Hochschule Mittweida (LHM) in Germany. After extensive practical experience during and after his studies in various areas of laser technology (laser welding, development of laser protection windows, ablation investigations using excimer lasers, laser micro sintering, surface structuring, etc.), he worked in the last five years in the field of additive manufacturing using lasers. After investigations on laser cladding and high rate micro cladding, he is currently working in the field of laser micro sintering and micro-SLM.
Manufacturing of micro heat exchangers by laser micro sintering
Synopsis: Conventional manufactured standard heat exchangers achieve compactnesses of 500 m² heat exchanger surface per m³. With the help of additive manufacturing, heat exchangers with compactnesses of up to 1,800 m²/m³ are now on the market. By additive manufacturing of metal components with structural resolutions of up to 35 μm, which has been used at the Laserinstitut Hochschule Mittweida since 2001, the mass of heat exchangers is to be further reduced and a compactness of up to 10,000 m²/m³ is to be achieved. The general geometric producibility of the required microstructures could already be proven in a preliminary project with the ILK Dresden. However, a first demonstrator in this preliminary project showed deficits in absolute tightness and had a very high production time. In the subsequent project, these and other problems (such as mounting the connections and removing the powder from the ducts) should be solved. The results achieved so far will be presented in this publication. If successful, the planned demonstrator of the micro heat exchanger will transfer an output of 5 - 10 kW at a transfer volume of 1 cm³, which would represent an enormous increase in power density.
