Patent attributes
A heat dissipation module includes an airflow generation device that generates airflow into an air channel in which a fin module is received and fixed. The fin module includes a plurality of fin plates substantially parallel to and spaced from each other to define air passages extending from an inlet to an outlet of the air channel. Each fin plate has a trailing section extending to the outlet and forming at least one inclined guide tab and an opening defined in the fin plate immediately close to the guide tab for switching at least a portion of the air between adjacent air passages on opposite sides of the fin plate. This increases the length of the path that the air flows through the air channel and thus raises the amount of heat exchanged between the fin plates and the air thereby enhancing efficiency of heat removal.
