Heat sink for cooling electronic chip
First Claim
1. A heat sink for discharging an electronic chip, comprising:
- a body contacting the surface of the electronic chip at one major surface thereof and received heat emitted from the surface of the electronic chip, the one major surface of the body being flat;
a plurality of heat discharge fins formed integrally with the body and adapted to discharge the heat, transferred to the body, to the atmosphere, the heat discharge fins being protruded from the other major surface of the body while being uniformed spaced from one another; and
a plurality of corrugated louver fin members each interposed between adjacent ones of the heat discharge fins and formed by repeatedly bending a thin plate member to have a wave shape, each of the corrugated louver fin members having a plurality of louvers adapted to create a turbulent flow of air while varying the direction of the air flow.

Abstract
Disclosed is a heat sink for discharging an electronic chip, including a body contacting the surface of the electronic chip at one major surface thereof and received heat emitted from the surface of the electronic chip, the one major surface of the body being flat; a plurality of heat discharge fins formed integrally with the body and adapted to discharge the heat, transferred to the body, to the atmosphere, the heat discharge fins being protruded from the other major surface of the body while being uniformed spaced from one another; and a plurality of corrugated louver fin members each interposed between adjacent ones of the heat discharge fins and formed by repeatedly bending a thin plate member to have a wave shape, each of the corrugated louver fin members having a plurality of louvers adapted to create a turbulent flow of air while varying the direction of the air flow. In accordance with the heat sink, it is possible to obtain a maximum heat conduction cross-sectional area and a maximum convective heat transfer area, thereby achieving a great improvement in heat discharge characteristics.
