Abstract
The disclosed apparatus may include (1) a cold plate base that (A) is thermally coupled to a component and (B) includes a set of heatsink fin structures that facilitate absorbing heat generated by the component and (2) a cold plate cover that (A) sits atop the cold plate base and (B) directs a cooling fluid across the set of heatsink fin structures to cool the cold plate base despite the heat absorbed by the cold plate base from the component. Various other apparatuses, systems, and methods are also disclosed.
Claims15
An apparatus comprising:
- a cold plate base that:
- is thermally coupled to a component;
- includes a first heatsink fin structure and a second heatsink fin structure that facilitate absorbing heat generated by the component;
- and
- forms a channel that sits between the first heatsink fin structure and the second heatsink fin structure;
- and
- a cold plate cover that:
- sits atop the cold plate base;
- includes at least one inlet port and at least one outlet port that collectively enable a cooling fluid to:
- enter the cold plate cover;
- pass over the first heatsink fin structure and the second heatsink fin structure included on the cold plate base;
- and
- exit the cold plate cover;
- directs the cooling fluid from the inlet port to the channel;
- includes an internal wall that:
- causes the cooling fluid to accumulate within the channel until the cooling fluid rises to a height of the first heatsink fin structure and the second heatsink fin structure;
- and
- once the cooling fluid has accumulated within the channel, causes the cooling fluid to flow:
- in one direction over a top of the first heatsink fin structure;
- and
- in an opposite direction over a top of the second heatsink fin structure.

A method comprising:
- thermally coupling, to a component, a cold plate base that:
- includes a first heatsink fin structure and a second heatsink fin structure that facilitate absorbing heat generated by the component;
- and
- forms a channel that sits between the first heatsink fin structure and the second heatsink fin structure;
- mating a cold plate cover with the cold plate base that is thermally coupled with the component, wherein the cold plate cover includes at least one inlet port and at least one outlet port that collectively enable a cooling fluid to:
- enter the cold plate cover;
- pass over the first heatsink fin structure and the second heatsink fin structure included on the cold plate base;
- and
- exit the cold plate cover;
- and
- directing the cooling fluid from the inlet port to the channel such that:
- the cooling fluid presses against an internal wall of the cold plate cover;
- the internal wall causes the cooling fluid to accumulate within the channel until the cooling fluid rises to a height of the first heatsink fin structure and the second heatsink fin structure;
- and
- once the cooling fluid has accumulated within the channel, the cooling fluid flows:
- in one direction over a top of the first heatsink fin structure;
- and
- in an opposite direction over a top of the second heatsink fin structure.
