Miniature Heat Exchanger

This counterflow water/water miniature heat exchanger was designed for and manufactured by Laser Beam Melting in order to demonstrate achievable efficiency compared to conventional plate heat exchangers.

The inlets with a diameter of  6mm fan out into 10 channels of 2 mm in diameter and a total length of 400 mm.

Each channel is meandering with 7 directional changes of 180°, having a distance of only 1.5 mm to each other. This leads to a very compact design while maximising the surface area.
