Abstract
According to various embodiments, there is provided a heat sink including: a heat conducting surface; a plurality of nozzle arrays arranged such that output ends of nozzles of the plurality of nozzle arrays face the heat conducting surface; and a plurality of fins configured to at least partially surround a respective portion of the heat conducting surface facing a respective nozzle array of the plurality of nozzle arrays.
Claims22
A heat sink comprising:
- a heat conducting surface;
- a plurality of nozzle arrays arranged such that output ends of nozzles of the plurality of nozzle arrays face the heat conducting surface;
- and
- a plurality of fins configured to at least partially surround each portion of the heat conducting surface facing a respective nozzle array of the plurality of nozzle arrays such that when a nozzle array of the plurality of nozzle arrays ejects a fluid, the plurality of fins direct the fluid ejected by the nozzle array to impinge on a corresponding portion of the heat conducting surface.

A heat sink comprising:
- a heat conducting surface;
- and
- a nozzle array arranged such that output ends of nozzles of the nozzle array face the heat conducting surface, the nozzle array comprising a first nozzle and a second nozzle;
- wherein a distance between the output end of the first nozzle and the heat conducting surface is shorter than a distance between the output end of the second nozzle and the heat conducting surface;
- wherein the first nozzle is longer than the second nozzle;
- and
- wherein each of the first nozzle and the second nozzle is configured to impinge a fluid onto the heat conducting surface.
4 more elements
A method for fabricating a heat sink, the method comprising:
- arranging a plurality of nozzle arrays such that output ends of nozzles of the plurality of nozzle arrays face a heat conducting surface;
- and
- at least partially surrounding each portion of the heat conducting surface facing a respective nozzle array of the plurality of nozzle arrays with a plurality of fins, such that when a nozzle array of the plurality of nozzle arrays ejects a fluid, the plurality of fins direct the fluid ejected by the nozzle array to impinge on a corresponding portion of the heat conducting surface.
