Abstract
The utility model discloses a passenger train air conditioning unit's ventilation duct, the wind channel is enclosed by the wallboard, each section live through I shape section bar buckle between the wind channel the section of wallboard, the outside visual face corner in wind channel is in order to follow wind channel length direction and with wallboard surface laminating along with the cladding of type section bar, between the wallboard the wallboard with it bonds to dip in glue with aluminium tinfoil paper STICKER between the I shape section bar on the butt joint face, the wallboard with along with bonding through glue between the type section bar. The utility model has the advantages that: the whole weight of ventilation duct is lighter, satisfies the passenger train and subtracts heavy requirement, wind channel configuration mode can be diversified, only need process out the wallboard of required shape and just can assemble, and manufacturing process is simple, the wallboard material is all optimized in performances such as fire -retardant, harmful gas and wastes material emission, sound insulation, heat preservation to some extent.
Description
Technical field
This utility model relates to the ventilation air duct of a kind of air conditioning unit air-supply, return air。
Background technology
In motorbus vehicle, each compartment generally be equipped with at least one air conditioning unit, air conditioning unit commonly used cellular structure, air conditioning unit complete machine is arranged in vehicle bottom or roof location。Air conditioning unit be connected with the air outlet in car and return air inlet by supply air duct and return airway, for the air after transport process in car to regulate air humidity in compartment and temperature。Supply air duct and return airway are generally arranged on the top of car inside ceiling panel, also have Some vehicles to be arranged on below floor and in side wall。
Mainly there are three kinds of versions in existing motorbus air conditioner ventilation air channel: metallic plate+cold-proof materials, metallic plate+cold-proof materials+metallic plate, fiberglass+insulation material structure。There is following defect in the air conditioner ventilation air channel adopting this structure:
1, complex manufacturing technology, relatively costly, maintenance inconvenience。Metallic plate needs the techniques such as uncoiling, blanking, bending and staking, and the pasted technique of fiberglass is also comparatively laborious。
2, the air channel deadweight that metallic plate and fiberglass make is heavier。Plate thickness is generally 1.5 to 2 millimeters, and fiberglass thickness is generally 4 millimeters。
Needing staking gluing to seal during the air channel molding of 3, metal plate structure, add the deformation of panel beating itself, outward appearance is not as attractive in appearance。
4, metallic plate and glass fibre reinforced plastic air channel are internal since it is desired that bonding cold-proof materials, gluing seal, so wind intracavity portion is not as fairing, air drag is big, the bad cleaning of easy adhering dust。
5, the gas and the dust that discharge in fiberglass manufacturing process are harmful, and glass fibre reinforced plastic waste is also very big to ecological environment harm。
Utility model content
Utility model purpose: for the problems referred to above, the purpose of this utility model is to provide a kind of combination property coach air conditioner unit ventilation air duct more preferably, and in the performances such as weight, windage, heat preservation and soundproof, effect is more superior。
Technical scheme: the ventilation air duct of a kind of coach air conditioner unit, described air channel is surrounded by wallboard, withheld the section of described wallboard by I shape section bar between each section of described air channel, the exterior visual face corner in described air channel with along described air channel length direction and with described panel surfaces fit with type section bar be coated with, between described wallboard, to dip in glue with aluminum tinfoil paper sticky paper on interface between described wallboard and described I shape section bar bonding, described wallboard with described with bonding by glue between type section bar。
Described wallboard is that glass fibre phenol formaldehyde foam strengthens plate, has excellent stiffness, fire-retardant, moistureproof, insulation, sound insulation function, makes maintenance cost low。
That described wallboard includes plane and cambered surface, it is possible to make as required, the exterior visual face that can be used as air channel of cambered surface。
Decorative adhesive film is posted in the exterior visual face in described air channel。
The exterior visual face in described air channel offers air port, as air outlet and return air inlet。
Beneficial effect: compared with prior art, the utility model has the advantages that: ventilation air duct overall weight is relatively light, meets the requirement of passenger vehicle loss of weight；Air channel structure mode can be diversified, and the wallboard that only need to process required form just can assemble, and manufacturing process is simple；Wallboard material all optimizes to some extent in the performances such as fire-retardant, harmful gas and waste discharge, sound insulation, insulation。

Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, it is further elucidated with this utility model, it should be understood that these embodiments are merely to illustrate this utility model rather than limit scope of the present utility model, after having read this utility model, the amendment of the various equivalent form of values of the present utility model is all fallen within the application claims limited range by those skilled in the art。
As shown in Figure 1, a kind of ventilation air duct of coach air conditioner unit, strengthened plate by glass fibre phenol formaldehyde foam and surround air channel as wallboard 1, glass fibre phenol formaldehyde foam strengthens plate and has excellent stiffness, fire-retardant, moistureproof, insulation, sound insulation function, harmful components are less, environmental hazard is few, making maintenance cost is low, shape and structure according to Duct design, wallboard is processed in accurate cutting process, it is possible to be plane, A, B plate as illustrated in the drawing, can being cambered surface, as illustrated in the drawing C plate, assembling can be enclosed and be made air channel。Dipping in specialty glue with aluminum tinfoil paper sticky paper on interface between wallboard bonding, strengthen bonding strength, to ensure the sealing property of junction, then this is sentenced metal forming stickup and can ensure that interface surface smoothing, and air resistance coefficient is little, and cleaning is convenient。
As shown in accompanying drawing 1,2, by being spliced to form longer air channel between each section of air channel, the section of wallboard 1 is withheld by adjacent two sections of connections by I shape section bar 2, namely wallboard is stuck in the U-shaped opening of I shape section bar, dips in specialty glue with aluminum tinfoil paper sticky paper bonding between wallboard with I shape section bar on interface。
As shown in accompanying drawing 1,3, to the exterior visual face C plate in air channel in its corner with A plate, B plate, adopt and being coated with type section bar 3 of panel surfaces laminating along air channel length direction, wallboard with bonding by specialty glue between type section bar。Exterior visual face C plate posts decorative adhesive film, C plate offers air port 4, as air outlet and return air inlet。
