Abstract
A cold plate includes an enclosure with an inlet, an outlet, a base and a lid. The inlet and outlet are in fluid communication, so fluid can flow from the inlet though the enclosure to the outlet. The base is formed from a base plate, and the base plate includes an island facing into the enclosure. A plurality of pins extends from the island toward the lid. The pins can have a spiral shape, where the cross sectional profile of the pins change along the length of the pin.
Claims26
A cold plate comprising:
- an enclosure having an inlet, an outlet, a base and a lid;
- a base plate forming the enclosure base, where the base plate includes an island;
- and
- a plurality of pins extending from the island toward the enclosure lid, the pins including a bottom where the pin connects to the base plate, a top opposite the bottom, a length extending from the bottom to the top, an axis central to the pin, a side surface, and a generally quadrilateral cross sectional profile having an orientation, where the orientation of the cross sectional profile spirals along the length of the pin, the axis bends along the length of the pin, the side surface includes at least two textures where one texture includes a plurality of dimples, and the pin and the base plate are monolithic.
A cold plate comprising:
- an enclosure having a base, a lid, an inlet and an outlet;
- a base plate forming the enclosure base, where the base plate includes an island;
- and
- a plurality of pins within the enclosure extending from the base plate toward the enclosure lid, where each pin has a length and a cross sectional profile with an orientation, and where the cross sectional profile orientation changes along the pin length.
A cold plate comprising:
- an enclosure having a base, a lid, an inlet, and an outlet;
- a base plate forming the enclosure base, where the base plate includes an island;
- and
- a plurality of pins extending from the island toward the enclosure lid, where each pin includes at least two textures, and where at least one texture includes a plurality of dimples.
A cold plate comprising:
- an enclosure having an inlet, an outlet, a base and a lid;
- a base plate forming the enclosure base, where the base plate includes an island;
- and
- a plurality of pins extending from the island toward the enclosure lid, where each pin includes a length and an axis, and where the axis bends along the pin length.
A cold plate comprising:
- an enclosure having an inlet, an outlet, a base and a lid;
- a base plate forming the enclosure base, where the base plate includes an island;
- and
- a plurality of pins extending from the island toward the enclosure lid, where each pin has a cross sectional area, a bottom where the pin connects to the island, and a top opposite the bottom, and where for at least a portion of the pin the cross sectional area increases with an increased distance from the pin bottom.
A method of producing a cold plate comprising:
- slicing a base plate to form a plurality of fins;
- cross-slicing the base plate after the fins are formed to form a plurality of pins;
- attaching a cover to the base plate such that the plurality of pins are contained within an enclosure between the cover and the base plate;
- and
- forming an inlet and an outlet to the enclosure.
