Detailed Description

The technical solution in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention.

The present embodiment discloses a ventilation and heat dissipation device for a cabinet, which is mainly assembled and assembled by an outer frame 100, a filter cotton 300 and an inner frame 200, as shown in fig. 1 to 5. The outer frame 100 and the inner frame 200 can be embedded with each other and fixed relatively by screws, so that the assembly and disassembly are convenient, the filter cotton 300 is used for dustproof filtration, and the filter cotton 300 is clamped and fixed between the outer frame 100 and the inner frame 200.

The structure of the outer frame 100 is as shown in fig. 4, the outer frame 100 includes a frame 101 and first cross bars 104, the frame 101 of the outer frame 100 is a rectangular frame formed by bending metal materials such as cold-rolled steel sheets or stainless steel sheets through metal plates, a ventilation opening is formed in the middle of the rectangular frame, the first cross bars 104 are arranged at the ventilation opening at equal intervals, and the end of each first cross bar 104 is welded on the inner wall of the frame 101. The first cross bar 104 may be made of metal strips, and the surfaces of the outer frame 100 and the first cross bar 104 may be treated with corrosion protection according to the environment. The frame 101 of the outer frame 100 is provided with fixing holes 102.

The structure of the inner frame 200 is as shown in fig. 5, the inner frame 200 comprises a frame and a second cross rod 207, the frame of the inner frame 200 is also made of cold-rolled steel plates or stainless steel and other metal materials and is bent into a rectangular frame through metal plates, a ventilation opening is formed in the middle of the rectangular frame, the rectangular frame is divided into an upper frame 201, a lower frame 202, a first side frame 203 and a second side frame 204, a plurality of second cross rods 207 are arranged at the ventilation opening at equal intervals, and the end portion of each second cross rod 207 is welded on the inner wall of the side frame. The second cross bar 207 can also be a metal strip, and the surfaces of the inner frame 200 and the second cross bar 207 can be correspondingly subjected to corrosion prevention treatment according to the use environment requirement. The inner frame 200 has fixing holes (not shown) formed in the rim thereof.

When the outer frame 100 and the inner frame 200 are fitted to each other, the frame of the inner frame 200 is fitted into the frame 101 of the outer frame 100, the frame walls of the two are bonded to each other, and the two are fixed to each other by screws inserted through the fixing holes 102. The filter cotton 300 is clamped between the outer frame 100 and the inner frame 200 (the filter cotton 300 is arranged between the plane where the first cross bars 104 are located and the plane where the second cross bars 207 are located), the filter cotton 300 covers the whole ventilation opening to play a role in dust prevention and filtration, and the clamped filter cotton 300 is naturally bent to form a wavy structure shown in fig. 3 by utilizing the matching of the first cross bars 104 and the second cross bars 207 which are respectively arranged on the outer frame 100 and the inner frame 200. The filter pulp 300 that is bent is more than directly tiling and is showing its filtration ventilation area and increase in vent department, and the filter pulp 300 after bending also can reduce ventilation resistance in addition, does not enlarge under the condition of vent size, can effectively improve ventilation efficiency, reaches better radiating effect, uses on the powerful electric cabinet of especially being applicable to.

In order to form the filter cotton 300 into a wave shape under the clamping of the first cross bars 104 and the second cross bars 207, after the outer frame 100 and the inner frame 200 are mutually embedded, the first cross bars 104 and the second cross bars 207 need to be in a staggered parallel arrangement, and the planes of the plurality of second cross bars 207 are closer to the outer surface of the vent of the outer frame 100 than the planes of the plurality of first cross bars 104, where the outer surface of the vent is the surface where the air enters the arrow marked on the side frame 101 of the outer frame 100 in fig. 4, and the direction of the arrow is the direction in which the air flows from the outside to the inside of the cabinet. Under the action of the bending of the cross rods in the front-back staggered manner, the filter cotton 300 forms a wave-shaped structure along the trend.

Further explaining the specific arrangement of each cross bar as follows: first sawtooth structures 103 are symmetrically arranged on the inner walls of a group of opposite side frames 101 of the outer frame 100, the first sawtooth structures 103 are formed by sequentially connecting a plurality of tooth shapes, the first sawtooth structures 103 are continuously distributed along the inner walls of the side frames 101, and the end part of each first cross rod 104 is fixed at each tooth-shaped peak in the first sawtooth structures 103 (the peak is a bulge towards the direction of the inner frame 200); second sawtooth structures 206 are symmetrically arranged on the inner walls of the first side frame 203 and the second side frame 204 of the inner frame 200, the second sawtooth structures 206 are formed by sequentially connecting a plurality of tooth shapes, the second sawtooth structures 206 are also continuously distributed along the inner walls of the side frames, and the end part of each second cross rod 207 is fixed at each tooth-shaped peak (the peak is a bulge towards the direction of the outer frame 100) in the second sawtooth structures 206; a plurality of clamping grooves 205 arranged at intervals are symmetrically formed in the first side frame 203 and the second side frame 204 of the inner frame 200 respectively, the clamping grooves 205 penetrate through the side frames, one end of the outer frame 100 is opened by the clamping grooves 205, the other opposite end of the clamping grooves 205 forms a limiting part, and each clamping groove 205 is arranged at each tooth-shaped trough in the second sawtooth structure 206; the frame of the inner frame 200 is embedded into the frame 101 of the outer frame 100, and each first cross bar 104 is just embedded into the corresponding slot 205, so that the second cross bar 207 is closer to the outdoor side, and the tooth-shaped peaks in the first sawtooth structures 103 just correspond to the tooth-shaped valleys in the second sawtooth structures 206.
