Abstract：
Arc–shape ventilation dormer realizes natural ventilation in building on the basis of fluid mechanics principle. And adopts direct transmission structure. Based on its application in a single–storey steel structure kiln, arc–shape ventilation dormer not only optimizes the joist supporting the dormer frame in the original structure and saves cost, but also guarantees product quality through factory component–type standardization production and greatly improves lighting and ventilation effects in workshop.
