Air discharge structure of industrial cabinet

Abstract

An air discharge structure of an industrial cabinet comprises at least one duct and at least one heat dissipating device, and the duct is installed at the rear and/or both sides of the industrial cabinet, and the heat dissipating device is installed at the top of the industrial cabinet and has at least one air inlet and at least one air outlet coupled to the top for extracting and discharging internal hot air of the industrial cabinet to the outside. The duct has a size corresponding to the size of a plurality of pillars of the industrial cabinet, so that the duct will not occupy the internal using space of the industrial cabinet.

What is claimed is: 
     
         1 . An air discharge structure of an industrial cabinet, installed inside the industrial cabinet, comprising:
 at least one duct, installed on at least one of side panels other than a front panel and having a plurality of through holes, such that a channel is formed inside the duct for guiding air; and   at least one heat dissipating device, installed at a top of the industrial cabinet, and having at least one air inlet and at least one air outlet, and the air inlet being coupled to the duct, and the heat dissipating device drawing hot air from the industrial cabinet through the through holes, such that the duct directs the hot air to pass through the air inlet and then discharges the hot air from the air outlet.   
     
     
         2 . The air discharge structure of an industrial cabinet as recited in  claim 1 , wherein the heat dissipating device is a vortex fan. 
     
     
         3 . The air discharge structure of an industrial cabinet as recited in  claim 1 , further comprising a heat collection cover for connecting the air outlet and gathering hot air. 
     
     
         4 . The air discharge structure of an industrial cabinet as recited in  claim 3 , further comprising an air guide tube with an end coupled to the heat collection cover and the other end coupled to the outside. 
     
     
         5 . The air discharge structure of an industrial cabinet as recited in  claim 4 , further comprising an air guide fan installed at a middle section of the air guide tube and provided for guiding and discharging air to the outside compulsorily. 
     
     
         6 . The air discharge structure of an industrial cabinet as recited in  claim 4 , further comprising an air collection box coupled to the air guide tubes and the outside, gathering hot air discharged from the industrial cabinets and discharging hot air to the outside, if a plurality of industrial cabinets being used. 
     
     
         7 . The air discharge structure of an industrial cabinet as recited in  claim 1 , wherein the duct is combined and installed at the rear of the industrial cabinet. 
     
     
         8 . The air discharge structure of an industrial cabinet as recited in  claim 1 , wherein the duct comes with a quantity of two and the ducts are installed on both left and right sides of the industrial cabinet respectively.
