Manifold for a coldplate cooling system
Disclosed is a coolant fluid manifold for coupling to a cold plate. The manifold includes an input channel including an inlet and an outlet. The inlet is configured to receive input coolant fluid. The input channel includes a guide element that projects from a wall of the input channel. The guide element is configured to guide fluid flow from the outlet.
1 . A coolant fluid manifold for coupling to a cold plate, the coolant fluid manifold comprising:
an input channel including an inlet and an outlet, wherein:
the inlet is configured to receive input coolant fluid,
the input channel includes a guide element configured to guide fluid flow from the outlet, and
the guide element includes:
a leading contact surface projecting from a top wall or a base wall of the input channel substantially perpendicular to a plane of the outlet, and leaving a gap between the guide element and the base wall or the top wall respectively,
a trailing contact surface tapering from the leading contact surface toward a sidewall of the input channel, and
shape and position of the leading contact surface and the trailing contact surface are configured to skew fluid flow from the inlet toward outputting a higher proportion of fluid proximate a center or a midpoint of the outlet while limiting fluid flow toward an edge of the input channel that corresponds to an outer wall of the cold plate.
2 . The coolant fluid manifold of claim 1 wherein the guide element has a height that is approximately half a height of the input channel.
3 . The coolant fluid manifold of claim 1 wherein the leading contact surface is inclined at a steeper angle than the trailing contact surface relative to the wall of the input channel wherefrom the guide element projects.
4 . The coolant fluid manifold of claim 1 wherein:
a lateral cross-section of the input channel has at least one of a v-shape or a curved v-shape;
the input channel includes a first sidewall and a second sidewall that each extend from the outlet to a vertex;
the inlet is provided proximate the vertex; and
the leading contact surface extends from the outlet to the first sidewall.
5 . The coolant fluid manifold of claim 4 wherein the guide element is offset from the inlet.
6 . The coolant fluid manifold of claim 1 wherein the guide element includes a fin or rib projection.
7 . The coolant fluid manifold of claim 1 further comprising a return channel including a return channel inlet and a return channel outlet.
8 . A cold plate cooling system comprising:
the coolant fluid manifold of claim 7 ; and
the cold plate, wherein the cold plate includes:
a body;
an input flow passage configured to interface with the outlet; and
a return flow passage configured to interface with the return channel inlet, wherein:
the input flow passage and the return flow passage each extend longitudinally through the body of the cold plate, and
a return manifold coupled to the input flow passage and the return flow passage, such that a fluid flow path extends from the inlet to the return channel outlet.
9 . The cold plate cooling system of claim 8 , wherein the guide element is shaped and positioned to at least partially deflect coolant fluid toward an inner wall of the cold plate.
10 . The cold plate cooling system of claim 9 , wherein:
the input flow passage includes at least a first passage and a second passage; and
the inner wall extends longitudinally through the body of the cold plate and at least partially separates the first passage from the second passage.
11 . The coolant fluid manifold of claim 1 wherein the guide element, by virtue of the leading contact surface and the trailing contact surface respectively, has a wedge shape or a curved wedge shape.
