Abstract
A heat preservation reinforced ventilation pipeline relates to the technical field of ventilation of air conditioners and is characterized in that a composite heat preservation plate comprises three layers, a heat preservation layer (2) is arranged in the middle of the composite heat preservation plate, the heat preservation layer (2) is made of polystyrene foam boards or phenolic foam boards or superfine glass fiber boards, reinforcing layers (1) are arranged on two sides of the composite heat preservation plate and made of corrugated aluminum foils or corrugated aluminum foil cloth, the four composite heat preservation plates are connected through the corrugated aluminum foils or the corrugated aluminum foil cloth of the outer layer reinforcing layer (1), grooves (4) are formed among the heat preservation layers (2) after the composite heat preservation plate is parallelly unfolded, the grooves (4) are in a step shape, and. Through above technical scheme, the life of ventilation pipe increases, has reduced the rate of leaking out, restraines the microorganism and survives, has reduced man-hour of installation, has reduced the cost of manufacture.
Description
The utility model relates to the air conditioner ventilation technical field, particularly a kind of ventilation duct.
Common ventilation duct adopts sheet metal or glass fibre reinforced plastics to make more on the market.Though metal vents fire prevention but perishable, insulation and noise elimination weak effect.Though the glass fibre reinforced plastics ventilation duct life-span is run well than metal, fire prevention, aging quality resistance is poor, and proportion is bigger, also is difficult for installing.
The purpose of this utility model provides a kind of corrosion-resistant, insulation, fire-retardant, the novel ventilated pipeline of eliminating the noise, easily installing.
Take following technological scheme for reaching above-mentioned purpose: the utility model cross section is a rectangle, constitute by four composite insulation boards, composite insulation boards has three layers of formation, the centre is a thermal insulation layer 2, thermal insulation layer 2 adopts foamed polystyrene board or phenolic foam plate, also can adopt super-fine glass fiber board, both sides are back-up coats 1, adopt waveform aluminium foil or waveform aluminium foil cloth; Connect by outer back-up coat 1 waveform aluminium foil or waveform aluminium foil cloth between four composite insulation boards, between the thermal insulation layer 2 of parallel expansion back groove 4 is arranged, groove 4 is stepped; The joint is bonding with tape paper 3.
The utility model groove 4 also can be V-arrangement.
By above technological scheme, increase the working life of ventilation duct, reduced air leak rate of air curtain, suppresses microorganism existence, reduced installation work-hour, reduced fabricating cost.
In conjunction with the accompanying drawings the utility model is being described in further details down.
Fig. 1 is the structural representation of composite insulation boards,
Fig. 2 is the insulation pipe structure schematic representation,
Fig. 3 is Fig. 2 thermal insulation pipe unfolded drawing,
Fig. 4 is the thermal insulation pipe schematic cross-section, and Fig. 5 is Fig. 4 thermal insulation pipe unfolded drawing.
During making, size is made foamed polystyrene board on request, pastes the waveform aluminium foil in foaming plate both sides then, makes composite insulation boards.On special device, carve groove 4.In groove 4, coat binder during assembling.Package is got up successively, sticks tape paper 3 at last in the joint and makes this reality and have novel.
Claims (2)
1, ventilation duct is strengthened in a kind of insulation, the cross section is a rectangle, constitute by four composite insulation boards, it is characterized in that: composite insulation boards has three layers of formation, and the centre is thermal insulation layer (2), and thermal insulation layer (2) adopts foamed polystyrene board, or phenolic foam plate, also can adopt super-fine glass fiber board, both sides are back-up coat (1), adopt waveform aluminium foil or waveform aluminium foil cloth; Connect by outer back-up coat (1) waveform aluminium foil or waveform aluminium foil cloth between four composite insulation boards, between the parallel expansion back thermal insulation layer (2) groove (4) is arranged, groove (4) is stepped; The joint is bonding with adhesive tape (3).
2, ventilation duct is strengthened in described insulation according to claim (1), it is characterized in that groove (4) also can be V-arrangement.
