<p>A CASING STRUCTURE FOR ELECTRICAL AND MECHANICAL UNITS A casing structure comprises a first casing unit (A) including a first compartment (A2) and a second compartment (A3), and a second casing unit (B) including a third compartment (B1), the second unit (B) pivotably connected to the first unit (A) so as to open or close with respect thereto. The three compartments (A2, A3, B1) have their respective inlets and outlets and connected in series through connecting passages including these outlets and inlets to define an air flow passage. A heat source (PU) accompanying with sound source, i.e., an electrical and mechanical unit, is arranged in the intermediate second compartment (A3) and an air cooling fan (19) is provided in the air flow passage in the vicinity of the heat unit (PU).</p> |
