FLEXIBLE HEAT EXCHANGER

摘要

A method for constructing a heat exchanger for cooling one or more semiconductor components comprises the step of providing first and second planar sheets of specified thermally conductive metal foil, wherein each of the sheets has and exterior side and an interior side. The method further comprises forming one or more thermal contact nodes (TCNs) in the first sheet, wherein each TCN extends outward from the exterior side of the first sheet, and comprises a planar contact member and one or more side sections, the side sections respectively including resilient components that enable the contact member of the TCN to move toward and away from the exterior side of the first sheet, and the side sections and contact member of a TCN collectively forming a coolant chamber. Channel segments are configured along the interior side of the first sheet, wherein each channel extends between the coolant chambers and two TCNs, or between the coolant chamber of a TCN and an input port or output port, selectively. The method further comprises joining the interior side of the second sheet to the interior side of the first sheet, in order to form a sealed flow path that includes each channel segment, and enables liquid coolant to flow into and out of the coolant chamber of each TCN.
