Abstract: A heat exchanger with a first manifold and a second manifold. The heat exchanger includes tubes having first and second ends. The tubes connect to the first manifold at the first end and the second manifold at the second end establishing fluid communication between the manifolds. The tubes are arranged parallel and forming gaps between tubes. The heat exchanger includes fin matrices formed from fins that span the gaps and extend from the first end to the second end. At least two adjacent tubes define an expansion gap that accommodates thermal expansion.
