Abstract
The invention relates to a flow channel of a heat exchanger with two parallel heat transfer areas (F1, F2) that are arranged at a distance corresponding to a channel height H. Each heat transfer area (F1, F2) is provided with a structure that is formed by a plurality of structural elements which are placed next to each other in rows running perpendicular to the direction of flow P and extend into the flow channel. Each structural element has a width B, a length L, a height h, a flow-off angle a, and an overlap U while being provided with a longitudinal axis.
Claims40
A flow passage of a heat exchanger, the flow passage being configured to allow a flow of a medium therethrough, and the flow passage comprising:
- a plurality of structure elements arranged in pairs such that each pair forms a V-shape;
- a first surface comprising a first plurality of the structure elements projecting into an interior of the flow passage and arranged in a first plurality of rows, wherein each of the rows in the first plurality of rows is transverse with respect to a direction of the flow;
- and
- a second surface comprising a second plurality of the structure elements projecting into the interior of the flow passage and arranged in a second plurality of rows, wherein each of the rows in the second plurality of rows is transverse with respect to the direction of the flow,
- wherein each of the rows in the first plurality of rows overlaps each of the rows in the second plurality of rows in the direction of the flow.
