Abstract

According to an example aspect, there is provided a matrix for a heat exchanger, which matrix is made of heat absorbing material and has a plurality of fluid flow channels extending there through in a flow direction of fluid. The flow channels have channel sections that are successive in the flow direction and at least partly staggered relative to each other.
