Abstract:
1. A heat dissipation module for dissipating heat from a heat-generating device comprising: an airflow generation device that generates an airflow; an air channel having an inlet receiving the airflow and an outlet on an end of the air channel opposing the inlet; and a fin module received and fixed in the air channel between the inlet and the outlet thereof for guiding the airflow from the inlet through the air channel to the outlet, the fin module comprising a plurality of fin plates substantially parallel to and spaced from each other to define therebetween air passages through each of which the air flow passes, each fin plate comprising: a trailing section positioned at the outlet of the air channel, the trailing section having formed thereon at least one first guide tab extending in a first oblique direction and having formed therein a first opening immediately adjacent to the first guide tab, the trailing section having formed thereon at least one second guide tab extending in a second oblique direction and having formed therein a second opening immediately adjacent to the second guide tab, wherein the first and second guide tabs are arranged in an alternating manner along the trailing section so as to guide at least a portion of air of the airflow in an air passage on one side of the fin plate to to flow in an adjacent air passage defined by an opposite side of the fin plate; and a leading section extending from the trailing section to the inlet of the air channel, the leading section having a smooth continuous surface at least equal in length to the trailing section.
