Abstract

The present invention relates to fins and a heat exchanger comprising same. The fin may comprise: a fin body including a tube insertion hole, which is open in a reference direction and is provided such that a tube extending in the reference direction is inserted therein, and an application hole, which is disposed above the tube insertion hole, communicates with the tube insertion hole, and is open in the reference direction; a first protrusion part protruding in the reference direction from a first edge region, which is a region defining the application hole of the fin body; and a second protrusion part protruding in the reference direction from a second edge region, which is a region defining the tube insertion hole of the fin body.
