Abstract: An air mixer cool plate (100) for dissipating heat from a plurality of heat-generating elements (22) positioned in an air stream (26). The plate is made from a material having a thermal conductivity preferably ranging from 1 to 500 watts/meter-K and is designed to be positioned to contact the top surfaces of the heat-generating elements. The plate includes a plurality of apertures (106, 108) and a plurality of upstanding air deflectors (110). The apertures and deflectors are arranged so that when the plate is supported in predetermined relation to the heat-generating elements and the air stream, the plate will cause the air stream to be deflected so as to flow in intimate contact with the elements, thereby carrying heat away from the elements by convection and conduction.

Abstract: An apparatus that provides a cooling system in which electronic components are serially configured in the air flow path and tilted down to form a "V" formation when viewed from the side. An air moving device draws air from an inlet, serially past first and second components and exhausts air through an outlet. This formation increases the inlet air opening, increases the area to turn the air in between the components, and increases the size of the plenum between the rear components and the air moving device, all without increasing the size of the electronic device. The larger area reduces the resistance of the air flow cooling path by reducing the number of turns and velocity changes of the air flow, which allows the air moving device to be smaller, use less power, and generate less noise.

From the interior of a container body 1, air flows out through an air outflow hole 17 to the exterior. The printed circuit board 21 can be cooled efficiently with a small air flow rate and an excellent performance of electromagnetic shielding can be achieved.
