Description

Technical Field

[0001] The utility model relates to a multi-air duct heat dissipation type industrial control cabinet. Background Art

[0002] Industrial control cabinets are cabinets used for control in power plants. They emit a lot of heat when in use. The current heat dissipation method is mainly through blowing heat dissipation, that is, an inlet fan is fixed on the lower side of the cabinet, and the external air is blown into the cabinet through the inlet fan, and then dissipated in the cabinet. An exhaust fan is fixed at the top of the cabinet, and the hot air is discharged through the exhaust fan to achieve the purpose of air flow heat dissipation. However, the external cold air entering this heat dissipation method is difficult to effectively blow the air to the heating element, which will make its heat dissipation efficiency low.

[0015] Reference Figure 1-Figure 5 A multi-duct heat dissipation industrial control cabinet, comprising: a cabinet body 2, air collecting cavities 5 are fixed to the bottom of both sides of the cabinet body, air inlet fans 6 are fixed to the bottom of both sides of the cabinet body, the air inlet fans adopt a conventional air inlet fan structure, which has a filter screen for filtering dust to prevent dust from being blown into the cabinet body, two vertical air pipes 3 are fixed to each of the air collecting cavities, the two vertical air pipes opposite to each other on both sides are connected by a blowing pipe 4, and a plurality of evenly arranged blowing holes 10 are opened on the upper surface of the blowing pipe.

[0016] The blowing pipe includes a left air duct 12, a right air duct 9 and a sleeve 11. The left air duct and the right air duct are respectively provided with a plurality of upward blowing holes 10. The ends of the left air duct and the right air duct are respectively provided with threaded pipe heads 13. The sleeve connects one end of the left air duct and the right air duct.

[0017] Working principle: Multiple air outlet screw holes are respectively provided on each vertical air duct, and each air outlet screw hole is threadedly connected with a plug to prevent air from coming out from here. When air outlet and heat dissipation are required, the plug at the position where the air blower is to be installed is unscrewed, and then the left air duct and the right air duct of the air blower are separated, first screw the left air duct on the vertical air duct on the left, and then put the sleeve on the left air duct, and then put the right air duct on the air blower on the right, and then slide the sleeve to put it on the left air duct and the right air duct. After the installation of several positions where the air blower is required is completed, the inlet fan is started, and the external air enters the air collecting cavity through the inlet fan, and enters each vertical air duct through the air collecting cavity, and then enters each air blower and is blown out through the blowing holes, so as to realize the blowing and heat dissipation of the heating elements in different positions and improve the heat dissipation efficiency.
