Abstract

A cooling scheme is provided which includes uninterruptible cooling with better reliability and modular expandability. A centralized uninterruptible air moving system is utilized which distributes air throughout the entire frame. The exhaust air is channelled to a machine cover which serves as a main exhaust duct. The arrangement allows for empty board positions, and also allows servicing without interrupting the overall system cooling.

Uninterruptible Modular Air Cooled System

A cooling scheme is provided which includes uninterruptible cooling with better reliability and modular expandability. A centralized uninterruptible air moving system is utilized which distributes air throughout the entire frame. The exhaust air is channelled to a machine cover which serves as a main exhaust duct. The arrangement allows for empty board positions, and also allows servicing without interrupting the overall system cooling.

The uninterruptible air moving system is shown in Fig. 3, wherein active redundancy is built-in which guarantees that air flow will be provided continuously. An additional blower 10 is provided, so that a blower failure or some other mishap will cause the air flow and temperature sensor 12 to sense an increase of temperature and drop of air flow. This change will be sent to the switching controller 14 which causes the device to switch-in the redundant Flower 10. An air flow control vane 16 automatically opens when this redundant blower is turned on.

The air flow to the system is through a main supply duct 18 seen in Fig. 2. The arrows in Figs. 1 and 2 represent the air flow.

The air flows through each side channel and up through the modules to be cooled. The exhaust is channelled into the cover where it rises out of the top opening 20 in the machine cover.
