1. Field of the Invention
The present invention relates to the technical field of a housing of electric equipments or components, in particular to the air distribution structure of an industrial cabinet that sucks cold air from the bottom of an industrial cabinet into the cabinet uniformly through a duct installed on a side of the cabinet to improve a cool house effect.
2. Description of the Related Art
In general, the industrial computer cabinet is used for containing a plurality of electronic equipments such as industrial computers or severs, and the temperature in the industrial computer cabinets will be increased by the heat generated during the operation of the electronic equipments. To prevent abnormality of the electronic equipments due to high temperature, the industrial computer cabinets generally come with a plurality of extraction fans installed at the rear of the computer cabinets for extracting internal hot air from the rear to the outside, and an airflow is produced to drive external cold air to flow into the computer cabinets from the front side to dissipate the heat. However, the industrial computer cabinets are installed in an air-conditioned engine room of a constant temperature. With the characteristics of the rising hot air and the descending cold air, air sucked from the front side is not the cold air with the lowest temperature around, so that the internal temperature of industrial computer cabinet cannot be lowered immediately.
With reference to
In view of the problems of the prior art, it is a primary objective of the present invention to provide an air distribution structure of an industrial cabinet, wherein after cold air outside the bottom of the industrial cabinet is sucked by an air intake device in the condition of not occupying any internal using space of the industrial cabinet, and then a vertical duct is used for delivering the cold air into each position inside the industrial cabinet to enhance the cool house effect of the cabinet.
To achieve the foregoing objective, the present invention provides an air distribution structure of an industrial cabinet installed inside the industrial cabinet, and the industrial cabinet comprises a pillar separately and vertically disposed at four corners of a top panel to define four sides, a door panel disposed at a front side, and a right panel, a left panel and a rear panel disposed on the remaining three sides respectively, and a plurality of electronic equipments disposed among the pillars to form a plurality of installation spaces, and the air distribution structure comprises a bottom box, at least one duct and at least one air intake device. The bottom box is coupled to the bottom of the pillars and has at least one air inlet and at least one air outlet. The duct is installed in at least one of the side panels other than the rear panel and disposed between the pillars, and an end of the duct is coupled to the air outlet, and a plurality of through holes is formed on a surface of the duct, and the duct has a size corresponding to the size of the pillars. The air intake device is installed inside the bottom box for producing a suction force to suck cold air near the ground from the air inlet, and the cold air is guided by the duct and delivered into the installation spaces uniformly to enhance the cool house effect of the cabinet.
Wherein, the air intake device is a vortex fan. The duct is installed on the door panel, and an end of the duct is separated from the air outlet when the door panel is opened, and coupled to the air outlet when the door panel is closed. Alternatively, two ducts are installed in the left panel and the right panel respectively, and an end of each duct is coupled to the air outlet. In addition, at least one wind outlet portion is disposed separately on the rear panel or the top panel. The air distribution structure of an industrial cabinet further comprises an airflow guide tube with an end coupled to the air inlet, and the other end coupled to a cold air source. If a plurality of industrial cabinets is used, the air distribution structure further comprises an air distribution tube coupled to the airflow guide tubes and the cold air source, and the industrial cabinets are connected to suck in cold air of a lower temperature to enhance the cool house effect of the cabinet significantly.
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
The air distribution structure 2 comprises a bottom box 20, at least one duct 21 and at least one air intake device 201. The bottom box 20 is coupled to the bottom of the pillars 300 and has at least one air inlet 202 and at least one air outlet 203. An end of the duct 21 is coupled to the air outlet 203 and the duct 21 has a plurality of through holes 210 formed on the duct 21 so as to form a channel therein for guiding air. In addition, the duct 21 has a size corresponding to the size of the pillars 300. In this preferred embodiment, the duct 21 is substantially in the shape of a rectangular box, and two ducts 21 are installed in the right panel 32 and the left panel 33 respectively, or combined on the door panel 31, and the ducts 21 are separated from the air outlet 203 when the door panel 31 is opened and the ducts 21 are coupled to the air outlet 203 when the door panel 31 is closed. Therefore, the duct 21 will not occupy any using space inside the industrial cabinet 3 and the position and size of the duct 21 can be adjusted flexibly to achieve the best cool house effect.
The air intake device 201 is installed inside the bottom box 20 and provided for producing a suction force to suck cold air proximate to the ground from the air inlet 202, and the cold air is passed through the duct 21 and delivered to the installation spaces uniformly to enhance the cool house effect. In addition, the air inlet 202 is formed at the bottom of the bottom box 20, and the air outlet 203 is formed at the top of the bottom box 20 and situated at a position corresponding to the duct 21, and a gauze or a filter can be installed to the air inlet 202, the air outlet 203 and the wind outlet portion 35 to reduce the chance for external dust or foreign substances to enter the industrial cabinet 3 and prevent the electronic equipments 4 from being damaged by the dust or foreign substances.
