DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

The technical contents of the present invention will become apparent with the detailed description of preferred embodiments and the illustration of related drawings as follows.
With reference to FIGS. 2 to 4 for an exploded view, a schematic view and a cross-sectional view of a preferred embodiment of the present invention respectively, an air discharge structure 2 of an industrial cabinet 3 is installed inside the industrial cabinet 3, and the industrial cabinet 3 is substantially in the shape of a rectangular box and comprises a top cover panel 30, a bottom retaining panel 31, a door panel 32 disposed at a front side of the industrial cabinet 3 and a right panel 33, a left panel 34 and a rear panel 35 disposed at the remaining three sides of the industrial cabinet 3 respectively. Pillars 36 are separately and vertically disposed at four corners of the top cover panel 30, and a plurality of electronic equipments 4 is installed between the pillars 36 to form plurality of installation spaces horizontally stacked on top of one another, and the top cover panel 30 has a top panel 37 disposed there below. The door panel 32 includes an air inlet 320 formed thereon for drawing nearby air into the industrial cabinet 3 to speed up the airflow inside the industrial cabinet 3. The air discharge structure 2 comprises a heat dissipating device 21 and a duct 20.
The heat dissipating device 21 is installed on the top panel 37 and has an air inlet 210 and an air outlet 211. In this preferred embodiment, the heat dissipating device 21 is a vortex fan for producing a suction force.
