Specific implementation mode
As depicted in figs. 1 and 2, this outdoor electric cabinet, including a cabinet 3, there are one electrical chamber 1, electricity for the intermediate tool of cabinet 3
One electrical cabinet mainboard 2 is installed, 1 lateral surface of the electrical chamber opening of cabinet 3, open end is packed into an electrical door-plate 5, electricity in air cavity 1
Stigmal plate 5 seals the open end of entire electrical chamber 1, and the front end face of electrical door-plate 5 opens up chamber 8 windward, windward the bottom surface of chamber 8
Open up a flotation chamber 11, flotation chamber 11 and chamber 8 windward are wide, windward the height of chamber 8 be more than flotation chamber 11 height, the two it
Between formed a step surface；
One float plate 9 is set in flotation chamber 11, and float plate 9 and flotation chamber 11 are wide, the embedded setting in top of float plate 9
One passes through the U-type groove opened up on electrical door-plate 5, U-type groove to open up with the wide connection sheet 7 of float plate, 7 other end of connection sheet
Between flotation chamber 11 and windward chamber 8, the other end of connection sheet 7 is pulled out from 8 one end of chamber windward, and the pull-out end of connection sheet 7 is solid
Surely it is bonded a limiting plate 6, more than one floating cooling mechanism 4 is arranged with respect to electrical cabinet mainboard in the inner end of float plate 9.
As shown in figure 4, floating cooling mechanism 4 includes a supporting sleeve 402, supporting pad 405, push rod 401, supporting pad 405 is set
It is placed in the bottom of supporting sleeve 402 and is bonded on electrical cabinet mainboard 2 by glue, push rod 401 is inserted in inside supporting sleeve 402
In plunger shaft, a sealing piston (not shown) is arranged in the insertion end of push rod 401, and sealing piston seals entire plunger shaft, supporting sleeve
More than one air blowing aperture 403 is provided on 402, the other end of push rod 401 is inserted and fixed to what 9 inner end of float plate opened up
In mounting hole.
As shown in figure 3, the top and bottom of chamber 8 uniformly open up more than one " L " type inlet channel 15 windward, face is each
One or more inlet push rod 12 is fixedly mounted on the limiting plate 6 of " L " type inlet channel 15, the output end of inlet push rod 12 is pacified
A pumping piston 13 is filled, pumping piston 13 seals " L " type inlet channel 15, opened on the electrical door-plate 5 of 6 side of limiting plate
If an exhaust hole 14, exhaust hole 14 is communicated with " L " type inlet channel 15, inner end and the electricity of " L " type inlet channel 15
Air cavity 1 communicates.
8 side of chamber is provided with the rib (not shown) of a circle to flotation chamber 11 windward relatively, and rib covers the four of float plate
A side, setting rib are mainly the sealing performance for increasing float plate and floating cavity wall contact surface.
Wherein, float plate 9 is metal float plate, in the case that it is calm can be by the float plate of metal to internal mainboard
It exchanges heat, heat dissipation performance greatly promotes.
There is wind, gas shock is in float plate so that the electrical cabinet mainboard of float plate relative interior moves, and makes
Obtain the push rod push-in of floating cooling mechanism so that the air in plunger shaft is discharged from air blowing aperture, to being evenly distributed on each electricity
