Abstract

A fin unit for a cooler includes a heat-conducting member, a plurality of helical elongate twisted fins and a fan. The heat-conducting member or a heat generator has its surface fixed with the plurality of helical elongated twisted fins. When the fan is started to operate, air convection is produced among the helical elongated members, forming helical whirls to increase contact and collision of the air with the helical elongated twisted fins, enhancing effect of heat dissipation.

Claims

1. A fin unit for a cooler comprising a heat-conducting member, a plurality of fins and a fan, said heat-conducting unit mounted on a heat generator, said fins formed as helical elongated twisted fins fixed on said heat-conducting member, said fan positioned above said helical elongated twisted fins, said fan started to operate to produce air convection among said helical elongated twisted fins to form helical whirls.

2. The fin unit for a cooler as claimed in claim 1, wherein the heat generator has its surface cut, drawn and twisted to form said helical elongated twisted fins.
