ABSTRACT:
The subject invention provides a heat sink for a liquid cooling system. The heat sink includes a spreader plate for contacting an electronic device and a body having a plurality of channels extending through the body and arranged in layers. Each layer includes a quantity of the channels decreasing in number with an increase in the distance from the electronic device, thus giving the heat sink a trapezoidal cross section perpendicular to the channels.
