Abstract: A heat exchanger tube includes a tube formed substantially of a heat conducting material, the tube being defined by a length, a height, and a width. The heat exchanger tube also includes at least one conduit formed within the tube and extending the length of the tube, the conduit defining an inlet at one end of the tube and the conduit defining an outlet at the opposite end of the tube, the conduit having a cross-section defined within the height and width of the tube, the cross-section having an oscillating geometry.

Abstract: An apparatus having an enclosure that is mountable on a computer rack. The apparatus comprising: a U-shaped plate, two end-caps, and a module having three faces. The U-shaped plate comprising a channel and forming a bottom face and at least a portion of the front and back faces of the enclosure. The module, which has three faces, is configured to mate with the U-shaped plate via the channel. When the module is mated with the U-shaped plate, the three faces of the module form, at least partially, the top, front and back faces of the enclosure. The two end-caps are configured to be attached to the U-shaped plate at distal ends of the U-shaped plate, wherein, when the two end-caps are attached to the U-shaped plate, side walls of the end-caps form two side faces of the enclosure.
