TLDR
In this article, a stretcher support frame with a bosh clamp and bosh base for connection with a printed circuit board was used to transport air via a circular air passage opening.Abstract:
The device has a stretcher support frame (4) with a bosh clamp and bosh base for connection with a printed circuit board (2). A small fan (3) has a fan propeller (31) which rotates around a rotational axis, such that air is transported via a circular air passage opening (47) of the board. An air directing unit (5) is provided on a side of the opening at the frame and returns flow direction of part of the air transported via the opening.read more
