Abstract
The utility model provides a self-breathing-type drying structure of a vehicle body. A ventilation film is added between the steel structure and the sound-insulating and heat-insulating layer of the vehicle body, so as to avoid the accumulation and penetration of the condensed water on the surface of the sound-insulating and heat-insulating layer and drain the condensed water out of the vehicle body through drain holes, thereby ensuring normal sound-insulating and heat-insulating performance of the sound-insulating and heat-insulating layer and avoiding the loss of the internal heat of the passenger vehicle caused by the heat bridge phenomenon. The self-breathing-type drying structure mainly comprises a vehicle body inner wall, a sound-insulating and heat-insulating plate and a vehicle body outer wall, wherein a ventilation film is arranged between the sound-insulating and heat-insulating plate and the vehicle body outer wall, a plurality of recessed drain troughs are formed between the ventilation film and the sound-insulating and heat-insulating plate as well as between the ventilation film and the vehicle body outer wall respectively, and drain holes formed at the bottom of the vehicle body outer wall to drain the condensed water out of the vehicle body therethrough. The self-breathing-type drying structure of the vehicle body is applied to the vehicle body steel structure and built-in side wall, the top plate, the floor plate, the end wall and the like.
Description
Technical field
The utility model is a kind of dry structure of car body self-respiration type that is applied to guideway vehicle, specifically the condensed water that forms between steel structure of car body and the sound-insulating and heat-insulating layer is drained into outside the car, belongs to mechanical manufacturing field.
Background technology
On the guideway vehicles such as the domestic urban light rail that has put into effect, subway, motor train unit,, be easy at present at the inner condensed water that produces of steel structure of car body because there are certain temperature difference in vehicle interior guest room and external environment.
Be lined with the sound-insulating layer in the car body of existing guideway vehicle is common, for example filling has a sound-insulating and heat-insulating plate between the parts such as side wall, top board, floor and headwall of steel structure of car body and interior dress, imports in the guest room with the operating noise of realizing keeping generation such as equipment under temperature in the vehicle passenger cab, isolated wheel track and the car.
The external environment of guideway vehicle operation normally with the guest room in environment form certain heal differential and psychrometric difference, this is just very easily at the inner condensed water that forms of steel structure of car body.Because the limitation of above-mentioned existing body construction has following use problem and defective:
At first, a large amount of condensed waters that produced in steel structure of car body inside are not under enclosed environment, and are volatile and accumulate in the sound-insulating and heat-insulating laminar surface for a long time, and condensed water penetrates into sound-insulating and heat-insulating layer inside will directly reduce sound insulation, heat insulation effect.The sound-insulating and heat-insulating layer has formed heat bridge phenomenon after making moist and absorbing water on the contrary, causes the passenger vehicle internal heat to be scattered and disappeared by the sound-insulating and heat-insulating course outward, takes environmental amenity in the guest room thereby have influence on.
Secondly, the condensed water that accumulates for a long time can corrode the steel structure of car body internal part, reduces the service life of matching component, thereby increases the cost of vehicle operating.
Once more, condensed water also can reduce the insulating power of steel structure of car body, and the normal operation of vehicle electric element system is brought certain harm.
The utility model content
The dry structure of car body self-respiration type described in the utility model, its design goal is to address the above problem and increases one deck ventilation film at steel structure of car body and sound-insulating and heat-insulating layer, stop condensed water gathering and infiltrate at the sound-insulating and heat-insulating laminar surface, and by drain gutter discharge car body, thereby the sound insulation, the heat-insulating property that guarantee the sound-insulating and heat-insulating layer are normally brought into play, and avoid causing scattering and disappearing of passenger vehicle internal heat because of forming heat bridge phenomenon.
Another design goal is that solution is accumulated condensed water for a long time and body part is caused corrosion failure, improves the service life of matching component effectively.
Design goal also is, avoids because of condensed water accumulates the insulating power that have influence on steel structure of car body, improves the operational safety performance of vehicle electric element system.
For realizing above-mentioned design goal, the dry structure of described car body self-respiration type mainly includes car body interior wall, sound-insulating and heat-insulating plate and car body exterior wall.
Be with the difference of prior art, one deck ventilation film be set between sound-insulating and heat-insulating plate and car body exterior wall,
Between ventilation film and sound-insulating and heat-insulating plate, the car body exterior wall, be formed with the drainage channel of several indents respectively,
Be provided with in the bottom of car body exterior wall condensed water is discharged drain gutter outside the car.
As above-mentioned basic scheme, the dry structure of car body self-respiration type can be applied to positions such as steel structure of car body and interior dress side wall, top board, floor, headwall.
The formed indent drainage channel in gap between ventilation film and sound-insulating and heat-insulating plate, the car body exterior wall forms the passage that condensed water accumulates back discharging outside car.
When ambient temperature was low, the inner condensed water that forms of steel structure of car body accumulated in the drainage channel gradually, is gathered together then and finally drains into outside the car by water vent.
For further improving at the converging of condensed water, discharge efficiency, reduce the contact time of condensed water and sound-insulating and heat-insulating plate simultaneously and reduce the probability of condensed water to the infiltration of sound-insulating and heat-insulating intralamellar part, can take following innovative approach:
The longitudinal profile of described ventilation film is a wave structure, this type of wave structure help condensed water along the drainage channel surface flow, converge, so the contact time of condensed water and sound-insulating and heat-insulating plate, area of contact are all less.
In fact, the formation of steel structure of car body internal condensation water mainly occurs in car body side wall place, and therefore preferred scheme can be that described drain gutter is arranged on the bottom of car body underframe side wall.
Drain gutter is arranged on the bottom of car body underframe side wall, and both having helped condensed water can all discharge, nor can have influence on the design of car body side wall overall appearance, rigidity and mechanical strength.
In sum, the dry structure of the utility model car body self-respiration type has the following advantages:
The ventilation film can stop condensed water the gathering and infiltrate of sound-insulating and heat-insulating laminar surface, thereby guarantees the normal performance of its sound insulation, heat-insulating property, avoids scattering and disappearing of passenger vehicle internal heat, improves the traveling comfort that inside, guest room is taken.
Solved because of condensed water accumulates the corrosion failure that body part is caused for a long time, improved the service life of matching component effectively.
Guarantee the insulating power of steel structure of car body, helped improving the safe in operation of vehicle electric element system.
