Abstract
The invention disclose a double louver-type ventilation grate comprising a frame (1) and a plurality of louver bars (2) which are arranged on the frame (1) at equal intervals; the louver bars are distributed up and down; the longitudinal cross section of each louver bar (2) is herringbone; ventilation channels (3) are formed between louver blades (2) arranged up and down at equal intervals; on the basis of ensuring the protection class, the ventilation channels inside and outside the shell of complete switch equipment are amplified, thus being beneficial to the heat radiation in the shell of the complete switch equipment.
Description
Technical field
The present invention relates to a kind of ventilation coral, particularly a kind of pair of venetian blind type ventilation coral.
Background technology
The degree of protection of existing switchgear assembly housing generally all is IP40, and the IP40 degree of protection requires the examination tool of diameter 1mm must not enter in the shell, prevents that metal wire is near dangerous parts.
Because electric elements equipped in the switchgear assembly housing all may generate heat, the switchgear assembly of bearing great current especially, temperature can rise very highly, if inner untimely the distributing of heat goes beyond the limit, will be accidents caused, work the mischief.
And will dispel the heat effectively, just louvre must be strengthened, but the excessive requirement that does not meet degree of protection again.For this reason,, just have to reduce the requirement of degree of protection sometimes, the switchgear assembly security performance is affected for effective heat radiation.
Summary of the invention
Technical problem to be solved by this invention provides a kind of when guaranteeing the degree of protection requirement, two venetian blind type ventilation corals that can efficiently radiates heat.
In order to solve above-mentioned technical problem, technical scheme of the present invention is: a kind of pair of venetian blind type ventilation coral, comprise framework and a plurality of two blinds bars that equidistantly are installed on the framework, a plurality of pairs of blinds bars distribute up and down, and the longitudinal cross-section of described pair of blinds bar is " people " font.
The longitudinal cross-section of An Zhuaning two blinds bars of being " people " font have constituted effectively " people " font vent passages up and down, help distributing of heat in the switchgear assembly housing.In addition, " people " font vent passages is non-straight channel, can prevent to try tool and other article directly enter in the switchgear assembly housing, has guaranteed degree of protection.
In order further to guarantee the safety in the switchgear assembly housing, the gap between the top of the two blinds bars under being installed in and the adjacent two blinds bars lower end that is installed in is less than 1mm.So just can avoid trying article such as tool by up and down between two two blinds bars the gap directly enter in the switchgear assembly housing.
The of the present invention pair of simple structure of venetian blind type ventilation coral utilization can effectively be dispelled the heat, and can be guaranteed the requirement of shell protection grade, guaranteed that device security stably moves in the switchgear assembly housing.
Description of drawings
The present invention is further detailed explanation below in conjunction with the drawings and specific embodiments.
Fig. 1 is a front view of the present invention.
Fig. 2 be among Fig. 1 A-A to cutaway view.
Embodiment
As shown in Figure 1, 2, a kind of pair of venetian blind type ventilation coral comprises framework 1 and a plurality of two blinds bars 2 that are installed on the framework 1, and described framework 1, two blinds bar 2 are finished framework 1 assembling earlier, in the groove on the framework 1 of more two blinds bars 2 being packed into by the steel plate manufacturing.
Two blinds bars 2 longitudinal cross-sections are " people " font, constituted vent passages 3 between two louvre blades 2 of equidistantly installing up and down, vent passages 3 has increased the inside and outside air duct of switchgear assembly housing on the basis that guarantees degree of protection, help distributing of the interior heat of switchgear assembly housing.
" people " font vent passages 3 is non-straight channel, can prevent to try tool and other article directly enter in the switchgear assembly housing, has guaranteed degree of protection.
A plurality of pairs of blinds bars 2 distribute up and down, and the gap between the top of the two blinds bars 2 under being installed in and adjacent two blinds bars 2 lower ends that are installed in is less than 1mm.So just can avoid trying article such as tool by up and down between two two blinds bars 2 gap directly enter in the switchgear assembly housing.
The foregoing description does not limit the present invention in any way, and every employing is equal to replaces or technical scheme that the mode of equivalent transformation obtains all drops in protection scope of the present invention.
Claims (2)
1. a two venetian blind type ventilation coral comprises framework (1) and a plurality of two blinds bars (2) that equidistantly are installed on the framework (1), and a plurality of pairs of blinds bars (2) distribute up and down, it is characterized in that: the longitudinal cross-section of described pair of blinds bar (2) is " people " font.
2. according to claim 1 pair of venetian blind type ventilation coral is characterized in that: the gap between the top of the two blinds bars (2) under being installed in and adjacent two blinds bars (2) lower end that is installed in is less than 1mm.
