Abstract
A thermal management device includes a wicking heat spreader and a boiling enhancement surface feature positioned on at least one interior surface of the wicking heat spreader.
Claims20
A thermal management device comprising:
- A wicking heat spreader, wherein the wicking heat spreader includes plurality of continuous horizontal rails, the plurality of continuous horizontal rails having a rail width and a rail height, and wherein the plurality of continuous horizontal rails decrease in cross-sectional area towards a center of the wicking heat spreader;
- and
- a boiling enhancement surface feature positioned on at least one interior surface of the wicking heat spreader.
A method of manufacturing a thermal management device, the method comprising:
- obtaining a frame of a wicking heat spreader, wherein the frame includes at least:
- a continuous vertical channel configured to allow fluid flow from a bottom surface of the wicking heat spreader to a top surface of the wicking heat spreader, and wherein the continuous vertical channel increases in volume toward the top surface of the wicking heat spreader;
- a continuous horizontal channel configured to allow fluid flow from a front surface of the wicking heat spreader to a rear surface of the wicking heat spreader, and wherein the continuous horizontal channel increases in volume toward a center of the wicking heat spreader;
- and
- forming at least one boiling enhancement surface feature on at least one interior surface of the frame.

A thermal management device comprising:
- a thermal interface material (TIM) configured to receive heat from a heat-generating component;
- an intermediate heat spreader contacting the TIM and configured to receive heat from the TIM;
- and
- a wicking heat spreader configured to receive heat from the intermediate heat spreader,
- wherein the wicking heat spreader includes:
- a continuous vertical channel configured to allow fluid flow from a bottom surface of the wicking heat spreader to a top surface of the wicking heat spreader, wherein the continuous vertical channel increases in volume towards the top surface of the wicking heat spreader,
- a continuous horizontal channel configured to allow fluid flow from a front surface of the wicking heat spreader to a rear surface of the wicking heat spreader, wherein the continuous horizontal channel increases in volume toward a center of the wicking heat spreader, and
- a boiling enhancement surface feature positioned on at least one interior surface of the wicking heat spreader.
