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.

Abstract: An air distribution structure of an industrial cabinet comprises a bottom box having at least one air intake device and at least one duct, and the bottom box is disposed at the bottom of the industrial cabinet and has an air inlet and an air outlet coupled to the duct for sucking cold air proximate to the ground and delivering the cold air into the industrial cabinet uniformly to enhance the cool house effect. 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.
