Patent ID: 7992625

Claim:
A heat transfer device, comprising: a chambered heat exchanger having interior surfaces defining an interior volume, the chambered heat exchanger having an inlet and an outlet for passage of liquid into and out of the interior volume; the chambered heat exchanger including: first pins extending from a first interior surface of the interior surfaces; first contours of a second interior surface of the interior surfaces being spaced apart from and at least substantially aligned with ends of the first pins; a portion of the first contours having first orifices extending from the second interior surface through to a third interior surface of the interior surfaces; and the third interior surface having a network of micro-channels intersecting the orifices, the network of micro-channels having micro-channel passages; wherein the first contours are dimples; wherein the chambered heat exchanger further includes: second pins extending from the second interior surface; second contours of the first interior surface being spaced apart from and at least substantially aligned with ends of the second pins; and the first pins and the second pins spaced apart from one another and overlapping one another with reference to vertical orientation thereof.
