Abstract

This ventilating system isolates incoming air from the heated exhaust air in stacked elements of a system frame and prevents cumulative preheating of electrical elements to be cooled. The design is bidirectional where flow in one direction is natural convection, and flow in the reverse direction can be obtained through a forced air convection system.

Ventilation System for Data Processing Systems

This ventilating system isolates incoming air from the heated exhaust air in stacked elements of a system frame and prevents cumulative preheating of electrical elements to be cooled. The design is bidirectional where flow in one direction is natural convection, and flow in the reverse direction can be obtained through a forced air convection system.

In the natural convection approach, air enters openings 10 in the front door of the cabinet and passes through areas in an inclined direction defined by members 11 to a vertical chimney 12, and thence up to the top of the cabinet and out through an optional filter 13. Modules 14 to be cooled are located between adjacent members 11 and are cooled by the air flow. Adjustable dampers 15 may be raised or lowered individually to adjust the air flow over a particular module 14.

Where heavier heat loads exist, a fan 16 may be used to force air in a direction opposite to that described above. Further, where the ambient air temperature outside the cabinet is too low, a strip heater 17 may be utilized to maintain the proper temperature of air surrounding modules 14.

With the above arrangement a large number of modules 14 may be stacked in a single cabinet that takes a minimum of floor space. Yet, efficient ventilation is provided for maintaining the proper operating temperature of the electrical modules.
