FORCED CONVECTION-DOUBLE FANIdeal for use with large IGBT, Diode and SCR modules in high wattage applications. Exceptional low thermal resistance, as low as 0.024 ˚C/W, provides more effective cooling per cubic inch of space compared to extruded heat sinks. Can be ordered complete with a high performance ball bearing fan installed or fan ready.

FORCED CONVECTION-TRIPLE FANIntegrate your design and put all of your power on one heat sink. If you are using more than one heat sink for different parts of your circuit, this could be the solution for you. Highest watt per cubic inch over other designs. Modules can be mounted parallel to the fins to eliminate upstream heating effect. This allows IGBT’s to all operate at the same temperature to increase system reliability. Can be ordered complete with a high performance ball bearing fan installed or fan ready.

Thermal specifications are based on 600 LFM airflow.


Available with ball bearing muffin XL fan. Ideal for IGBT and power MOSFET applications as well as diode and SCR bridges. Extremely low cost per watt. The impingement cooling allows modules to be mounted close together. This allows the IGBT’s to operate at the same temperature, increasing system reliability. This also allows for shorter bus bars, resulting in lower circuit inductance.

IMPINGEMENT HEAT SINKS

CUSTOM BONDED FIN HEAT SINKS

Forced air and natural convection profiles are available in a variety of finishes. The ability to choose from various configurations enables the engineer to tailor the heat sink profile to meet specific thermal needs of the application. By using the chart on the following page, fin spacing, profile width, heat sink length, fin height and mounting options can all be selected. Approximate thermal resistance’s are given for common fin height. They are calculated with airflow of 500 LFM and a heat sink length of 5 inches. Increases in airflow, fin height, heat sink length will provide higher thermal performance.

Ordering Information

Using the example on the following page and drawing below, heat sinks are selected from the table of options using the following format:
