onda by patrick pradel from italy

The Onda radiator concept was inspired from a scarf that flaps in the wind.
The structure is formed by two corrugated sheets of metal. The front one is characterized by a curved shape with aesthetical appeal. The rear one is a simple T section plate. Water flows from top to bottom in between the two sheets. The former radiator exchanges heat by radiation through the curved surface. The latter exchanges heat by convection through the T section.
