Bionic absorber: The new generation of solar collectors

Sun Master Energiesysteme GmbH has developed a new generation of solar collectors. In the development of the "bionic.absorber", the company was inspired by nature: the heat transfer is not effected as in the case of conventional absorbers, by a heat transfer medium located below the sheet in welded raw materials, but directly to the absorber sheet through channels as a leaf of a tree.

The optimization of the heat transfer results in a performance increase, which however does not have a negative effect on the production costs. This increase in the conduction is due to the flow through the collector.

The design of the collector corresponds to an optimum size ratio, which corresponds to the golden section and allows a full-surface heat transfer.

The implementation in the production was a challenge for the team consisting of engineers, developers and technicians. A manufacturing technique from the automotive industry served as a model for the innovative manufacturing process. The bionic solar collectors were delivered in 2013.
