HEAT EXCHANGER

The present invention discloses a heat exchanger for heat exchange between a first fluid and a second fluid. The heat exchanger includes a first manifold, a second manifold, and heat exchange tubes. The heat exchange tubes is axially extending and providing a fluidal communication between the first manifold and the second manifold for the first fluid. Further, the first fluid flows from the first manifold to the second manifold in the first fluid direction and the second fluid flows between the heat exchange tubes in the second fluid direction perpendicular to the first fluid direction. The heat exchanger further includes a fin section provided in contact with the heat exchange tubes for facilitating heat exchange between the first fluid and the second fluid. The fin section further includes a primary louver located on the fin section and a secondary louver location on the primary louver.
