A cooling apparatus for cooling electrical devices W,X,Y,Z using a flow of coolant comprises a duct 35, 37 through which the coolant flows past the devices W, X, Y, Z. The duct 35, 37 includes a first inlet 45, 45' for a first stream of coolant and a second inlet 41, 43 for a second stream of coolant downstream of the first inlet 45, 45'. The cooling apparatus also has a deflector 26 downstream of the second inlet 41, 43. In an alternative embodiment the cooling apparatus comprises a first inlet for a first stream of coolant, a second inlet downstream of the first inlet for a second stream of coolant, wherein the width of the second inlet is less than 50% of the width of the duct at the second inlet. In a further embodiment the cooling apparatus comprises a baffle in a duct for restricting the flow of a first stream of coolant past a device in the duct and a channel for transporting a second stream of coolant past the device and into the duct. In another embodiment the cooling apparatus comprises a channel for transporting a flow of coolant, the channel having an outlet, such that the outlet is adjacent an electrical device. |
