Abstract
A heat sink for use in an immersion cooling system that includes a sintered powder structure enclosed in a porous enclosure. The porous enclosure has openings, e.g., formed by a mesh, with a size to help contain sintered powder particles that may be dislodged during operation of the heat sink.
Claims24
An immersion cooling system, comprising:
- a tank configured to hold a cooling liquid;
- a heat generating device arranged in the tank and configured to generate heat;
- a heat sink thermally coupled to the heat generating device and including,
- a base coupled to the heat generating device so as to receive heat from the heat generating device,
- a sintered powder thermally coupled to the base and configured to receive heat from the base and transfer the heat to the cooling liquid, the sintered powder including sintered particles that are joined together to form a contiguous structure having spaces between particles to form fluid passageways in the contiguous structure to permit cooling liquid to flow into the fluid passageways and permit vapor bubbles generated by transfer of heat from the sintered powder to the cooling liquid to flow out of the passageways, and
- a porous enclosure that is attached to the base and configured to enclose the sintered powder, the porous enclosure including openings having a size to permit cooling liquid and vapor bubbles in the cooling liquid to pass through the porous enclosure and to prevent passage of individual sintered powder particles dislodged from the contiguous structure from passing through the porous enclosure.

A heat sink for use in cooling a heat generating device in an immersion cooling system, comprising:
- a base configured to couple with the heat generating device so as to receive heat from the heat generating device, the base including a plurality of fins;
- a sintered powder thermally coupled to the base, arranged to form a coating having a thickness over the plurality of fins, and configured to receive heat from the base and transfer the heat to a cooling liquid in the immersion cooling system, the sintered powder including particles that are joined together to form a contiguous structure having spaces between particles to form fluid passageways in the contiguous structure to permit cooling liquid to flow into the fluid passageways and permit vapor bubbles generated by transfer of heat from the sintered powder to the cooling liquid to flow out of the passageways;
- and
- a porous enclosure that is attached to the base and configured to enclose the sintered powder, the porous enclosure including openings having a size to permit cooling liquid and vapor bubbles in the cooling liquid to pass through the porous enclosure and to prevent passage of individual sintered powder particles dislodged from the contiguous structure from passing through the porous enclosure.
