CN203309391U - Heat-preservation flexible aluminum air pipe for rail vehicle - Google Patents

Abstract

The utility model relates to a heat-preservation flexible aluminum air pipe for a rail vehicle. The heat-preservation flexible aluminum air pipe comprises an air pipe body (1), wherein the cross section of the air pipe body (1) is of a rectangle or flat oval or polygon shape, the surface of the air pipe body (1) is of a corrugation shape, the air pipe body (1) is made of aluminum tapes, and a heat-preservation layer (2) is arranged on the outer surface of the air pipe body (1). According to the heat-preservation flexible aluminum air pipe for the rail vehicle, the air pipe body is formed by die-pressing and stretching the aluminum tapes, thereby having quite good ductility and better free bending properties; when the air pipe body is in a bending state, the size of an internal opening of the cross section of the air pipe body is kept unchanged, so that ventilation quantity is ensured; moreover, the heat-preservation layer is additionally arranged outside the air pipe body, therefore, condensate water can be prevented from being generated as a result of air temperature difference, and the environmental protection property and the heat-preservation property of the air pipe are enhanced.

Description

Insulating aluminium matter flexible duct for rail vehicle

Technical field

The utility model relates to a kind of airduct, belongs to the pipe technology field.

Background technique

In the rail traffic vehicles air conditioner ventilating system, airduct is the changeover portion that connects air-conditioning duct and exhaust outlet.Airduct in the past generally all adopts rubber pneumatic hose or PE pneumatic hose, and the defect of this type of airduct is: environmental-protecting performance is poor, poisonous, and thermal insulation property is poor, working life is short, reusable edible not, and this type of pipe is generally straight tube, can not be in any direction, under any angle, bending, affect ventilation.

Summary of the invention

The purpose of this utility model is to overcome above-mentioned deficiency, provides a kind of volume little, lightweight, environment-protecting asepsis, good heat insulating guaranteed simultaneously ventilation, can be in any direction, the Insulating aluminium matter flexible duct of arbitrarily angled lower bending.

The purpose of this utility model is achieved in that

A kind of matter of Insulating aluminium for rail vehicle flexible duct, comprise the airduct body, be characterized in: the cross section of described airduct body is rectangle or flat oval shape or polygonal, the surface of described airduct body is corrugated, the employing aluminium strip material of described airduct body is made, and the outer surface of described airduct body is provided with thermal insulation layer.

A kind of matter of Insulating aluminium for rail vehicle of the utility model flexible duct, its thermal insulation layer adopt adiabatic noise reduction, withstand voltage material anticorrosion and flame-retarding characteristic to make.

Compared with prior art, the beneficial effects of the utility model are:

A kind of matter of Insulating aluminium for rail vehicle of the utility model flexible duct, its airduct body by aluminium strip mold pressing drawing and forming after, volume is little, lightweight, and has good ductility, thereby make it have preferably arbitrarily bending properties, bent state lower section internal orifice size remains unchanged, and has guaranteed ventilation, the additional thermal insulation layer of airduct body can prevent because Air Temperature Difference forms condensed water in addition, has improved the feature of environmental protection and the heat insulating ability of airduct.
