AAVID HIGH POWER HEAT SINKS IMPROVE COOLING PERFORMANCE BY 15%

Bonded Fin Polar Cap(TM) Heat Sinks Give Engineers Increased
 Flexibility in Cooling IGBT or Thermal Electric Modules


LACONIA, N.H., March 4 /PRNewswire/ -- Aavid Thermal Technologies, Inc. (Nasdaq: AATT) announces a new line of heat sinks that increase efficiency, economy and cooling characteristics for designers of systems incorporating IGBTs or thermoelectric modules. Aavid's Polar Cap(TM) bonded fin heat sinks utilize impingement cooling techniques to reduce temperature rise, increase design flexibility, and to more efficiently cool high power electronics modules such as telecommunications power amplifiers and motor drives.

Unlike fixed height, crosscut extrusions used in other impingement cooled products, designers can vary the overall height of Polar Cap bonded fin heat sinks with little impact on cost and delivery. This gives the product designer many advantages in increased heat removal and packaging flexibility. As expected, thermal performance continues to increase proportionally with increased fin height.

Polar Cap's perpendicularly mounted cooling fans help promote turbulence and increase heat transfer. The resulting amount of heat removed per cubic inch of heat sink volume is greater than conventionally cooled heat sinks. Mounting points in the outside fins securely attach the fan to the fin tips, allowing air flow perpendicular to the heat input mounting surface. "Aavid's unique design directs the impingement cooling air to the back of the mounting surface, putting the maximum airflow to where it will do the most good," says Chris Soule, product marketing manager for high power at Aavid. "This change in air direction causes significant air flow turbulence, increasing the transfer and removal of heat. Impingement cooling of the bonded fin parts increases thermal performance by 10 to 15% over conventionally cooled devices of the same size."

Pricing and Availability

Aavid's Polar Cap heat sinks are available in a variety of standard sizes with and without the cooling fan. Aavid can also make custom size parts to fit virtually any application.

Pricing of Polar Cap parts range from the smallest size (4.85 inches square) at $44.00 per 500 prices to the largest size (6.95 x 10.36) at $98.00 per 500 pieces. Prices include the cooling fan. Delivery is four weeks or less depending on stock availability. For additional product and pricing information contact: Aavid customer service, Aavid Thermal Technologies, Inc., 603-528-3400.

Aavid also offers industry leading analytical and testing capabilities, providing custom Polar Cap heat sink solutions optimized for economics, performance, and reliability around the air flow and ambient temperature conditions present in a specific design.
