Abstract
Methods of fabricating cooling apparatuses with coolant filters are provided which facilitate heat transfer from an electronic component(s). The method includes providing a cooling apparatus which includes a liquid-cooled heat sink with a thermally conductive structure having a coolant-carrying compartment including a region of reduced cross-sectional coolant flow area. The heat sink includes a coolant inlet and outlet in fluid communication with the compartment, and the region of reduced cross-sectional coolant flow area provides an increased effective heat transfer coefficient between a main heat transfer surface of the conductive structure and the coolant. A coolant loop is also provided coupled to the coolant inlet and outlet to facilitate flow of coolant through the coolant-carrying compartment, and a coolant filter positioned to filter contaminants from the coolant passing through the heat sink. The coolant filter has a larger cross-sectional coolant flow area than the region of reduced cross-sectional coolant flow area.
