The Chill Block with PT (Power Tab) is an innovative liquid cooling solution specifically
designed for semiconductors housed in Power Tab packages. This compact, high-
performance cold plate directly interfaces with the exposed metal tab of power
semiconductors, providing an efficient thermal path from junction to coolant. Perfect for
space-constrained applications requiring exceptional cooling density, this chill block
combines compact form factor with impressive thermal performance.
How It Works
The Chill Block with PT features a precision-machined mounting surface that directly
contacts the Power Tab package's thermal interface. Internal cooling channels are positioned
immediately beneath this contact surface, minimizing thermal resistance between the
semiconductor junction and cooling fluid. High-velocity coolant flow through optimized
channel geometry creates turbulent flow conditions that maximize convective heat transfer.
The compact block design concentrates cooling capacity exactly where needed, efficiently
extracting heat from the small footprint of Power Tab packages. Multiple mounting options
accommodate various Power Tab orientations and PCB layouts. The direct liquid cooling
approach eliminates intermediate thermal interfaces present in traditional air-cooled
solutions, dramatically improving thermal performance in a fraction of the space.
