Detailed description of the invention
Below against accompanying drawing, by the description to embodiment, detailed description of the invention of the present utility model is described in further detail.
The low-voltage distribution cabinet of this utility model ventilation and heat, as shown in Figure 1, including longeron and the crossbeam 1 being connected to longeron top and bottom, top and bottom crossbeam 1 is equipped with air vent 2, and on crossbeam 1, it is provided with the Air Filter 3 covering air vent 2, it is connected with the ventilation brows 4 of multiple louvre outside crossbeam 1.
In this utility model, as it is shown on figure 3, crossbeam 1 structural representation, air vent 2 is the elongated hole along crossbeam 1 lateral arrangement, and is provided with demarcation strip in the middle part of elongated hole, to ensure Air Filter 3 stability of strutting system thereon.
Crossbeam 1 is the channel-section steel structure with flange, and as shown in Figure 4,5, Air Filter 3 both sides are provided with the location scrap (bridge) 32 being connected on crossbeam about 1 flange.The location scrap (bridge) 32 being positioned at upside is provided with corresponding dowel hole with upper overturning, during connection, first passes through alignment pin and from top to bottom positions.It is equipped with at the two ends of Air Filter 3 and middle part and the connecting hole I 31 being connected to crossbeam 1 is installed, the connecting hole I 31 at two ends is located by connecting on crossbeam 1 in the installing hole I 11 of 2 liang of side positions of air vent by attachment screw correspondence, in the installing hole I 11 that middle part connecting hole I 31 correspondence is positioned in air vent 2 on divider plate, three-point fix is to realize being stably connected with.
In this utility model, ventilation brows 4 structure is as shown in Figure 6, it is perforated plate-like structure, ventilation brows 4 are equivalently-sized with crossbeam 1, ventilation brows 4 circumference is provided with the multiple connecting holes II 41 being connected to crossbeam 1, and is fixedly connected on crossbeam 1 last week of installing hole II upwards by attachment screw through connecting hole II 41.Preferably, each attachment screw is provided with the separation pad between ventilation brows 4 and crossbeam 1, i.e. will be separated out certain distance between ventilation brows 4 and crossbeam 1 by separation pad, leave small-gap suture to ensure sufficient drain radiating effect, improve its heat-sinking capability.
