Microfluidics thermal management flow patterns and schemas

A device for thermal management comprising:

• a heat-generating component having an outer surface;
• a body connected to the heat-generating component;
• a microfluidic cooling volume contacting the outer surface and defined by the outer surface and the body;
• and
• at least one microfluidic thermal element positioned on the outer surface according to a channel design based at least partially on a heat generation map of the outer surface and in the microfluidic volume to transfer heat from the heat-generating component to a working fluid in the microfluidic volume.

A method for manufacturing a processing unit, the method comprising:

• modeling a thermal management demand of a processing unit on an outer surface of a die of the processing unit as a heat generation map;
• selecting an initial channel design for the outer surface of the die;
• evaluating the initial channel design, wherein evaluated metrics of the initial channel design include at least pressure drop and thermal resistance of the initial channel design;
• changing at least one parameter of the initial channel design based on the evaluated metrics to create a refined channel design;
• evaluating the refined channel design, wherein evaluated metrics of the refined channel design include at least pressure drop and thermal resistance of the refined channel design;
• changing at least one parameter of the refined channel design based on the evaluated metrics of the refined channel design to create another refined channel design;
• and
• forming at least one thermal element in or on the outer surface of the die according to the another refined channel design.
