Abstract
To achieve an improvement of heat exchanger effectiveness (heat transfer rate) without any increase of a fan motor output. The gas heated by the heating units or the gas cooled down by the cooling units is sent to the blowing nozzlesby a fan. Then, the blowing nozzlesblow the gas sent by the fan through their outlets. Each of the outlets has a non-circular planar shape with a projection portion thereof being projected inwardly. This allows a shape of the gas in cross section perpendicular to a direction where the gas is blown through the outlet of each of the blowing nozzlesto be changed by the projection portion with time (switching phenomenon). Such a switching phenomenon enables to be increased the heat exchanger effectiveness (heat transfer rate) on the printed board even if any output of the fan motor for rotating the fan does not increase.
