Exposed Tube Liquid Cooling Plates

Exposed tube liquid cold plates ensure minimum thermal resistance between the power device and the cold plate by placing the coolant tube in direct contact with the power device’s base. Direct contact reduces the number of thermal interfaces between device and fluid thus increasing performance for the application.

 

To create liquid cooling plates with exposed tubes, the tube in a plate by machining a groove in the plate. The tube can either be placed toward the top surface of the plate to provide better cooling to devices mounted on that surface, or it can be embedded further into the plate so that it cools devices mounted on both sides of the plate.

 

This option provides greater flexibility, but the thermal performance is limited because of the surface area of the tube perimeter
