Abstract
The invention belongs to electronic equipment chassis field, particularly a kind of ventilation rainproof structure.The present invention is by using increase weather shield, and weather shield is coordinated to be improved casing structure, meet ventilation rainproof requirement, and can meets the new structure of salt fog test requirement, experiment proves that working well, can stop drench with rain into interiors of products completely, without any water mark in cabinet, it is simple in construction, easily realize, there is good Practical significance.
Description
Technical field
The invention belongs to electronic equipment chassis field, particularly a kind of ventilation rainproof structure.
Background technology
It is stronger and stronger with the function of aircraft, requirement to air environment also more and more higher.It is many at present airborne
Electronic equipment is required to carry out salt fog test.For the product divulged information of needs, if not drenching with rain safeguard procedures, during experiment
Rainwater may enter interiors of products by air vent, it is likely that short circuit can be caused can not to pass through experiment so as to trigger failure.
The content of the invention
The purpose of the present invention：Air-conditioning requirement can be met by having invented one kind, and and can meets to drench with rain the new structure shape of requirement
Formula.
Technical scheme：A kind of ventilation rainproof structure, including machine case body, it is characterised in that：Cabinet top is set
In respect of groove, there is boss in groove, groove top is provided with weather shield, and bottom portion of groove surrounding is designed with osculum.
Air vent is set on the boss in groove, and air vent upper surface is higher than groove floor, less than groove top and gear
Rain plate contact surface.
There is multigroup wiper bar on weather shield, there is air vent, air vent and the air vent on cabinet between every group of wiper bar
Stagger, every group of wiper bar corresponds with the boss in groove.
Wiper bar lower surface is less than boss ventilation hole surface.
Bottom portion of groove surrounding osculum, which is less than in groove, boss height.
The surrounding draining bore dia at least will be in more than 5mm.
Bore dia of divulging information should match in more than 2.5mm, the power consumption with needing to radiate.
Width between every group of wiper bar is wider more than 4mm than boss.
Advantages of the present invention effect：
The present invention coordinates weather shield to be improved casing structure by using increase weather shield, meets ventilation rainproof
It is required that and can meets the new structure of salt fog test requirement, experiment proves that work well, can stop completely drench with rain into
Enter interiors of products, it is simple in construction without any water mark in cabinet, easily realize, there is good Practical significance.
Brief description of the drawings
Fig. 1 cabinet overall structure forms
Fig. 2 Each parts
Fig. 3 relativeness dimensional forms
Embodiment
The present invention is further described below in conjunction with the accompanying drawings：
As shown in figure 1, a kind of ventilation rainproof structure, including machine case body, cabinet upper design is fluted, has in groove convex
Platform, boss height should be not less than 4mm, to prevent water from entering cabinet inside because tension force covers boss.Groove top is provided with
Weather shield, is provided with wiper bar on weather shield, and the width between wiper bar should be wider more than 4mm than boss, in favor of divulging information and subtracting
Small windage.Bottom portion of groove surrounding is designed with osculum, and draining bore dia should can be prevented because the tension force of water causes to arrange in more than 5mm
The not smooth situation of water occurs.Air vent is set on the boss in groove, and air vent upper surface is higher than groove floor, less than groove
Top and weather shield contact surface, the diameter of air vent should be in more than 2.5mm, and the power consumption with needing to radiate matches, and is meeting
The requirement of radiating is small to reduce windage as far as possible.
There is multigroup wiper bar on weather shield, have air vent between every group of wiper bar, air vent and the air vent on cabinet are wrong
Open, prevent from drenching with rain falls directly into cabinet inside by the air vent on boss.A pair of boss 1 in every group of wiper bar and groove
Should, wiper bar lower surface prevents from drenching with rain in the air vent to splash on boss less than boss ventilation hole surface 1mm or so.Groove
Bottom surrounding osculum can effectively discharge ponding without entering in the air vent in boss less than having boss height in groove.
