Description
Technical field
The utility model belongs to rail vehicle, and in particular to electrical cubicle under a kind of rail traffic vehicles car.
Background technology
The rail traffic vehicles integrated system huge as one, because installation space is limited on car, considers simultaneously
The difficulty of Maintenance and Repair on to car.Therefore, it is generally the case that need the equipment of Maintenance and Repair to be more inclined under car and install.Such as
The batteries of rail traffic vehicles, it is necessary to periodic maintenance and cell batteries own wt is heavier, if using being installed under car,
Largely facilitate the attended operation of maintainer, but from another point of view, compared to electric component installation onboard, under car
Running environment rather harsh.While ventilation and heat to be ensured, to prevent that rainwater or the outer dust of car are directly entered electrically under car
Shield in cabinet.
The ventilation and heat structure of electrical cubicle is as shown in Figure 1 under existing rail vehicle car.Using in electrical cubicle cabinet 1
Heat emission hole 7 is opened in side, in the one piece of bucker 5 of outside welding of screen cabinet heat radiation hole 7.The structure of bucker 5 is as shown in Fig. 2 using plate
Material bending is formed, and steam vent 6 is provided with the bending edges of bucker 5 one, in welding, being provided with the bending edges of steam vent 6 down,
Rainwater is prevented to be directly entered in screen cabinet space.
According to air-flow character and principle of expanding with heat and contracting with cold, because electrical cubicle Inside Air Temperature is higher than surrounding enviroment
Temperature, air can flow up in thermal histories.An apparent defect of electrical cubicle radiating mode is just under existing car
It is that heat emission hole is arranged on electrical cubicle side, hot-spot phenomenon in cabinet can be caused.Reason is air in the case of heated, heat
Air is shielding cabinet flows upward inside, after the resistance at the top of cabinet is run into, turns back to heat emission hole and discharges, and surrounding environment
Cold air does heat exchange, and the temperature shielded inside cabinet is reduced to reach.It is empty that a heat can be thus formed at the top of electrical cubicle
Gas concentrated area, cabinet top area overheat, reduces the reliability for shielding cabinet internal electrical components.On the other hand, it is existing this
Kind waterproof heat dissipation structure, in the case that rainwater is big under car, rainwater still can penetrate into inside screen cabinet under capillary action.
Utility model content
In view of the above-mentioned problems, the utility model is aimed to provide under radiating and the good rail traffic vehicles car of water proof and dust proof effect
Electrical cubicle.
The utility model solve problem technical scheme be：Electrical cubicle under a kind of rail traffic vehicles car, including cabinet,
Through hole is provided with the top of cabinet, through hole is provided with and can cover through hole and make the heat dissipating housing that gas is discharged upwards in cabinet；
The heat dissipating housing top sides edge, which is provided with, can prevent swelling to the waterproof enclosing at the top of heat dissipating housing；
Being fixedly connected with the top of cabinet can be described dust-proof by heat dissipating housing and waterproof enclosing while the hollow dust cover covered
Gap is left between cover top seal, bottom-open, dust cover and heat dissipating housing and waterproof enclosing；
Gap is left between at the top of dust cover side lower end and cabinet, the discharge that the gap forms gas in cabinet is led to
Road.
In such scheme, according to the flow behavior of hot-air, heat emission hole is changed and is set at the top of cabinet, beneficial to radiating.
When water accumulating volume is big under car, although the upper surface of heat dissipating housing is higher than electrical cubicle upper surface, ponding can
It can be entered by way of infiltration along radiating cover outer surface inside electrical cubicle, influence the reliability of electric component in cabinet.Dissipate
Heat cover itself has certain altitude, and its upper surface is higher than electrical cubicle upper surface, and coordinates waterproof enclosing, even if electric screen cabinet top
There is ponding in portion, and ponding is also unlikely to enter inside electrical cubicle by heat dissipating housing.
Specifically, the heat dissipating housing includes the hollow cover body of bottom-open, is arranged at the heat emission hole of covering on top.
The waterproof enclosing includes the hollow box of bottom-open, and box body bottom-open, box body top is provided with and heat emission hole
The shape identical open ports of distributed areas, box body top open ports are fixed with assembling at the top of heat dissipating housing, and box body top is in water
Square upward size is at the top of heat dissipating housing；
Cover body side is surrounded in box body side, leaves gap between box body side and cover body side, box body side lower end with
Gap is left between at the top of cabinet.
Gap is left between the dust cover side and box body side, between being left at the top of dust cover between heat dissipating housing top
Gap, box body top are concordant with the top of heat dissipating housing.
Preferably, the gap between dust cover side lower end and cabinet top is 3~6 millimeters.Can in the range of being somebody's turn to do
Ensure the smooth discharge of radiating air, and can stops that most of rainwater enters.
Preferably, the contact site of the heat dissipating housing and cabinet sets sealing gasket.
Remarkable result of the present utility model is：
1. according to the flow behavior of hot-air, heat emission hole is changed and is set at the top of cabinet, beneficial to radiating.
2. dust cover can prevent larger particles dust from passing through.
3. if ponding is by penetrating into dust cover at the top of cabinet, ponding can only enter the side of waterproof enclosing with
The region to be formed is surrounded in heat dissipating housing side, and the region can prevent ponding from pouring in heat emission hole upwards, it is entirely avoided ponding enters electricity
Inside air screen cabinet.
