Claim of US Patent No. 10,091,909

1. A cooling arrangement, comprising:a heat spreader comprising a first surface, a second surface, at least one heat absorption chamber and at least one heat dissipation chamber, the at least one heat absorption chamber being in thermal contact with the first surface and the at least one heat dissipation chamber being in thermal contact with the second surface and hydraulically coupled to the at least one heat absorption chamber;
at least one heat generating component arranged in thermal contact with the first surface of the heat spreader;
a cooling fluid, filling at least part of the heat absorption chamber and the heat dissipation chamber;
at least one actuator for driving the cooling fluid; and
a controller for generating at least one control signal for the at least one actuator, such that the cooling fluid can be driven through the at least one heat absorption chamber using a plurality of flow patterns;
wherein the heat spreader comprises a plurality of regions and associated temperature sensors, the plurality of temperature sensors are coupled to the controller, and the controller programmed to identify at least one cold region of the heat spreader, the at least one cold region being characterized in that it has a temperature below an average temperature of the plurality of regions, and the controller is further programmed to generate at least one control signal based on the at least one identified cold region, such that the flow of cooling fluid is sourced from the at least one cold region in at least one flow pattern.
