Abstract
A heat exchanger system is provided and includes a heat sink, fins arrayed on a central region of the heat sink to form channels between adjacent fins and an integrated blower. Each of the fins extends radially outwardly from the central region and has a height that increases with increasing distance from the central region. The integrated blower is disposed at the central region to generate flows of coolant directed into and through the channels.
Claims18
A heat exchanger system, comprising:
- a heat sink;
- fins arrayed on a central region of the heat sink to form channels between adjacent fins, the fins being arranged in a spiraling formation and each of the fins extending radially outwardly from the central region and having a height that steadily increases with increasing distance from the central region;
- an integrated blower disposed at the central region to generate flows of coolant directed into and through the channels;
- and
- one or more baffles disposed to extend between adjacent fins, each baffle tapering to a narrow leading edge with decreasing distance toward the central region and bifurcating the corresponding one of the channels between the adjacent fins in a height-wise dimension of the fins.

A heat exchanger system, comprising:
- a heat sink having a surface with a central region and a periphery;
- fins arrayed on the surface to form channels between adjacent fins, the fins being arranged in a spiraling formation and each of the fins extending along the surface from the central region toward the periphery and having a height that is defined in a direction normal to the surface and steadily increases with increasing distance from the central region such that the channels extend along the surface from the central region toward the periphery and steadily increase in height from the surface with increasing distance from the central region;
- and
- an integrated blower disposed at the central region to generate flows of coolant directed into and through the channels;
- and
- one or more baffles disposed to extend between adjacent fins, each baffle tapering to a narrow leading edge with decreasing distance toward the central region and bifurcating the corresponding one of the channels between the adjacent fins in a height-wise dimension of the fins.

- an integrated blower disposed at the central region to generate flows of coolant directed into and through the channels;
- and
- one or more baffles disposed to extend between adjacent fins, each baffle tapering to a narrow leading edge with decreasing distance toward the central region and bifurcating the corresponding one of the channels between the adjacent fins in a height-wise dimension of the fins.
