The specific embodiment
Below in conjunction with drawings and Examples the utility model is described in detail.
As shown in Figure 1, the utility model is included in the electric apparatus room top one fully enclosed top cover 1 is set, and at least one air filter 2 is installed on top cover 1, and at least one ventilating set 3 is installed on the top ceiling between top cover 1 and the electric apparatus room.Top cover 1 is except that the position that filter 2 and ventilating set 3 are installed can ventilate, and all the other are sealing, makes air and the interior air insulated of electric apparatus room in the top cover.If the top cover of the existing airtight isolation in electric apparatus room top, can be on the fully enclosed top cover perforate filter 2 is installed and ventilating set 3 gets final product.The filter 2 subtend external worlds can receive extraneous natural wind and filtration, in the ventilating set 3 ventilation inlet subtend top covers 1, and in the air outlet subtend electric apparatus room, can be facing to the electrical equipment blowing.
As Fig. 2, Fig. 3, shown in Figure 4, leak free cover body 21 around filter 2 comprises, the rear and front end of cover body 21 has opening 22,23, keeps air penetrating.The bottom of cover body 21 is provided with interlayer, offers ease dirt hole 24 on interlayer, and is provided with disposal box 25 below ease dirt hole 24.In cover body 21, be provided with three layers of mozzle 26,27,28 of vertically arranging from air intake one side direction air-out one side.After three layers of mozzle 26,27,28, be provided with bed filtration expanded metals 29 again.Outside air can penetrate from mozzle 26,27,28 and filtration expanded metals 29 successively.
