A guide for supporting a device in a flow of coolant includes a deflector for modifying the coolant flow. The guide include apertures so that the coolant can flow over both the upper and lower faces of a device, for example a printed circuit board

Flow guide

A cooling apparatus for cooling an electrical device using a flow of coolant comprises a cooling unit . The cooling unit is in contact with the device and includes a channel for transporting the coolant past the device . In a preferred embodiment, the sectional area of the channel decreases between the inlet and the outlet of the channel . The velocity of the flow of coolant past the device can be modified, thus improving the efficiency of cooling.

Cooling devices

Cooling apparatus is used to cool equipment, for example electrical equipment, using a fan. In an embodiment described, the cooling apparatus comprises a duct for communication with the fan and for transporting air past the equipment. The duct may include a diffuser for improving the air flow in the duct.
