Non-Uniform Height And Density Fin Design For Heat Sink

A heat sink, comprising:

• a heat sink plate;
• an electrical component support directly connected to a first side of the heat sink plate having at least one heat generating electrical component mounted to the electrical component support;
• a plurality of fins connected and oriented perpendicular to a second side of the heat sink plate, the plurality of fins including:
• at least one maximum height fin positioned proximate to the electrical component;
• first and second minimum height fins each oppositely positioned with respect to the at least one maximum height fin and spatially separated from the electrical component;
• a first group of fins positioned between the at least one maximum height fin and the first minimum height fin, each fin of the first group of fins progressively decreasing in height from a height of the at least one maximum height fin to a height of the first minimum height fin;
• and
• a second group of fins positioned between the at least one maximum height fin and the second minimum height fin, each fin of the second group of fins progressively decreasing in height from the height of the at least one maximum height fin to a height of the second minimum height fin.
