Embodiment Construction

[0008] Referring to the accompanying drawings, the structure is that the inner louvers 3 are welded on the cabinet door or side wall 1; the interceptor 4 is sealed and installed on the sprayed cabinet / box door or side wall; the air duct storehouse 2 is sealed and installed on the cabinet door / box or On the side wall;

[0009] Improve the position of the air inlet of the cabinet / box louvers, and arrange them on the symmetrical plane of the louvers—the size of the original louvers is the same. The inner and outer louvers are arranged symmetrically, and there is one less inner louver at the lower end. Then the inside louver 3 is sealed with the intercepting funnel 4 with the upper end open, and finally the air duct storehouse 2 with the dust-proof net at the bottom is sealed and installed on the inner side 9 of the cabinet door.

[0010] The assembly and working process of the air duct on the cabinet: Weld the inner louvers 3 on the cabinet door or the side wall 1. The intercept...

Abstract

This invention is used as protective structure in outdoor cabinet / box of duct. Its structure is: the inside shutter is welded to doors or wall of the cabinet; the interceptor is installed hermetically in the door or wall after spraying; wind road store is installed hermetically in the door or wall; dust prevention network is installed under the wind road warehouse. When the cabinet forms negative pressure, the flow will be from outside cabinet ministry into interceptor and then from the dust prevention network at the bottom of the road wind store into cabinet through wind road. The advantages are as following: because the air inlet position's increase and the wind direction's changing, the possibility of the masons and large dust particles can be eliminated into the cabinet or blockage of dust network, and the amount of the fine dust particles into cabinet can be greatly reduced, the dust prevention effect can be greatly improved. Because of the addition of inside shutter and interceptor, the flow spray to the inside of the outer shutter will be reflected and pool to interceptor and then flow out of the cabinet, and will not flow into the cabinet. This fully meet IP55 level of GB4208 standard protection required.

Description

technical field [0001] The invention relates to a novel air duct protection structure used in outdoor cabinets / boxes, and belongs to the technical field of outdoor cabinet / box manufacturing Background technique [0002] Most of the existing outdoor cabinets / boxes use ventilation to dissipate heat. The muddy water is also easy to enter. In addition, dust or muddy water will block the dustproof net, resulting in poor ventilation of the outdoor cabinet / box and affecting the normal operation of the equipment. The GB4208 standard stipulates the requirements for the IP protection level. Generally, the active equipment has higher requirements for the working environment, and it is required to meet the IP55 standard. Obviously, the straight-through air duct protection structure cannot meet the requirements. Contents of the invention [0003] The object of the present invention is to propose a novel air duct protection structure for outdoor cabinets / cabinets in view of the above...
