Product Overview:

High Efficiency Laser Diode Heatpipe-Heatsink-Fan Assembly

The HS-004 is a high quality and versatile integrated heatsink and fan assembly, designed for maximum flexibility across a wide range of applications in your laser diode test lab and prototype shop. The mounting plate is nickel-plated for durability and improved heat conduction. Heatpipes are soldered into the nickel-plated mounting plate to minimize thermal spreading resistance, distribute the heat across the heatsink, and minimize efficiency-robbing thermal hot spots.

The HS-004 is a very affordable solution for a wide range of situations where a fully integrated thermoelectric cooled mount is overkill or over-budget. The HS-004 is perfect when high amounts of heat must be conducted away from the test device, but precision temperature control of the device is not required. The HS-004 provides laser heat dissipation capacity of 300 watts with 12 ºC temperature rise (12 ºC without TECs, 0 ºC rise with optimized TECs).

The HS-004 heatsink is ideal for a wide variety of fiber-coupled laser packages and modules, IGBTs, high-heat test loads, and the like.

The HS-004 comes with a high quality terminal block for fan wiring. The five high power fans are hidden inside of the air duct, reducing the noise significantly.

Low Thermal Resistance for High Heat-Flux Diode Laser Devices

Heatpipes are used in the HS-008 to maximize conduction of heat from the load to the heatsink and improve overall efficiency by reducing local hot-spots on the mounting plate.

The heatsink fins are forged in place and are designed to break up laminar airflow, which further improves heat dissipation efficiency. Finally, the high fin-density heatsink is enclosed in a sheet metal duct to direct the entire volume of forced air over the fins, thereby providing the low thermal resistance of 0.04 ºC/W. This low thermal resistance means that for every 10 Watts of power input to the heat-sink mounting plate, the temperature of the heatsink surface will rise 0.4 ºC.

Customizable Options for Maximum Versatility and Ease-of-Use

All heatsink modules can be ordered with an optional IP68 fan for operating in harsh dust and liquid environments. Also, custom mounting pre-drilled hole patterns are available from the manufacturer. Contact us for details and a quote.
