Abstract

A fan mounting is described that permits easy replacement of defective cooling fans used in compactly packaged equipment by the customer, without the need for tools. A mounting frame is provided with clips for easy location in a bulkhead and a printed circuit board PCB connector for simultaneously making electrical connection with a complementary edge connector on the bulkhead of the unit. The design possesses the advantages of self-alignment when plugging in the fan plus built-in shock mounts and noise isolation. The PCB board also lends itself to local sensing and control of temperature by speed regulation.

Pluggable Fan Assembly

A fan mounting is described that permits easy replacement of defective cooling fans used in compactly packaged equipment by the customer, without the need for tools. A mounting frame is provided with clips for easy location in a bulkhead and a printed circuit board PCB connector for simultaneously making electrical connection with a complementary edge connector on the bulkhead of the unit. The design possesses the advantages of self-alignment when plugging in the fan plus built-in shock mounts and noise isolation. The PCB board also lends itself to local sensing and control of temperature by speed regulation.

A fan of traditional axial design 1 is fixed by four urethane shock mounts 2 to a plastic molded frame 3. Features on frame 3 include two spring latches 4 for snapping the fan assembly into slots 10 on a chassis bulkhead 5, pillars 6, for locating and fixing a small printed circuit card board 7 and labyrinth periphery groove 11 to control short circuit airflow without short circuiting shock mounts. The fan motor 1 is hard-wired to the small PCB 7 which is clipped into position on the pillars 6.

Fan assembly 9 may be snapped into any plate mounting or bulkhead 5, as required. An edge connector 8 for the small PCB 7 would be required on the bulkhead for electrical connection. To release the fan from the bulkhead, the latches 4 can be released by hand, thus allowing easy removal of the fan for replacement.
