ABSTRACT:
A high performance cold plate cooling device including multiple, relatively thin plates, each having patterns formed thereon that, as arranged within the device, cause turbulence in a fluid passing within the cooling device. Adjacent plates within the cooling device are arranged such that fluid channels within their patterns are arranged crosswise. One or more barriers extending at least a portion of the length of the device separate the crosswise channels into two or more flow sections and increase uniformity of thermal performance over the active plate area. Manufacturing of the device includes stacking the plates in an alternating fashion such that the channels within the pattern of each plate are crosswise with respect to the channels in the pattern of an adjacent plate and adjacent barrier walls abut. A method of manufacturing a cooling device is also provided.
