Abstract: A side-exhaust heat dissipation module for cooling an electronic device. The side-exhaust heat dissipation module comprises a base, a fan, a fin assembly and an airflow guiding cover. The fan is disposed on one side of the base. The fin assembly is disposed on the base and composed of a plurality of parallel fins. The fin assembly has a concave end spaced from the fan by a predetermined distance. The airflow guiding cover is disposed on the fin assembly. The airflow guiding cover is gradually expanded and extended from the fan to cover the fin assembly.

Abstract: A heat dissipation module. The heat dissipation module comprises a cover, a fan, a base and a plurality of fin assemblies. The fan is disposed on the cover. The base is disposed underneath the fan and has a protruding portion. The protruding portion has two slant surfaces and a top end. The protruding portion gradually tapers toward the fan. The plurality of fin assemblies are disposed on the slant surfaces of the protruding portion of the base.
