Product Overview:

The model HS-004 is a low profile high power density heat sink module designed for fiber coupled laser diode modules. It offers an ultra low thermal resistance of 0.04ºC/W. It uses a combination of high density fins and soldered-in heat pipes to assist with heat spreading. it is ideal for cooling very high power lasers. Model HS-004 is a compact high performance fan and heat sink combo designed for general cooling of high heat flux devices. The heat sinks are nickel plated with integrated heat pipes that are soldered in place to maximize heat transfer. Heat pipes are known to have extremely high thermal conductivity. 6 heat pipes ensure that the heat from any concentrated heat source on the base is spread over the entire base. This minimizes the spreading resistance and maximizes the effectiveness of the heat sink fins. The fins are forged in place. Forged fins are much more superior than bonded fins because there are no low conductivity epoxies at the joint between the fins and heat sink’s base. The fins are also periodically segmented to break down the laminar layer of the airflow. Breaking down the laminar air flow increases turbulence and improves cooling effectiveness. 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. Custom mounting holes patterns is available upon request or users can add their own mounting.
