D6 offers this series of 5 inches wide 4 pass cold plates to meet the demanding needs of the power dissipation presented by IGBTs and Power Diodes. The 5-inch wide plate allows for 1 or multiple rows of devices with the tubing prepared in a serpentine pattern of 4 passes. A substantial area of each device is cooled by 4 tubes and copper inserts therefore providing a low thermal resistance between the device or devices and the liquid coolant.
