Abstract
A composite heat insulation air duct relates to the air-conditioning supporting facilities, particularly to the design of composite air duct. The utility model aims at providing a composite heat insulation air duct which is of no die, simple manufacturing, low cost and small labor intensity. The utility model is composed of three layers, namely, a glass-magnesium plate layer, a polystyrene extruded foam board heat preservation layer and a foldable outer protective layer, from inside to outside; the three layers are bonded together. Compared with the existing air duct, the utility model eliminates the method that one size requires one die, which is simple in manufacturing; the inner glass-magnesium plate layer is of anti-corrosion performance and long service life; the foldable outer protective layer can adopt aluminum foil, tin leaf or flame-retardant polyester foil, which has good fire-retardant, waterproof, corrosion resistant performances.
Description
(1) technical field
The utility model relates to the air-conditioning auxiliary facility, especially the design of composite air duct.
(2) background technique
The existing supporting inorganic compounding thermal insulation wind pipe internal and external layer of central air-conditioner is a FRIM, the mesosphere is a thermal insulation layer, and this airduct must be made airduct then with the wooden die mould of making base earlier on mould, long construction period, expense height, labor intensity are big, and the scene can not be changed.
(3) summary of the invention
The purpose of this utility model provide a kind of need not mould, make the hvac duct simple, that expense is low, labor intensity is little.
The utility model is achieved in that hvac duct, constitutes by three layers, and it is characterized in that: be followed successively by glass magnesium flaggy, polystyrene extrusion molding foam-board thermal insulation layer from the inside to the outside and can roll over external protection, each layer sticks with glue to connect and form.
The utility model has the advantages that: compare with existing airduct; eliminated the way of a mould of a kind of size; make simple; internal layer glass magnesium flaggy is anticorrosion, fire prevention, protection against the tide; long service life; can roll over external protection and can adopt aluminium foil, tinfoil paper or flame retardant polyester composite insulating foil, have good fire-retardant, waterproof, decay resistance.
(4) description of drawings
Accompanying drawing is the utility model structural representation.
(5) embodiment
Hvac duct; internal layer glass magnesium flaggy 1 and polystyrene extrusion molding foam-board thermal insulation layer 2; stick with glue and connect; size, shape are made into ventilation duct on request; it is bonding with polystyrene extrusion molding foam-board thermal insulation layer 2 to roll over external protection 3 with glue then, can roll over external protection and can adopt aluminium foil, tinfoil paper or flame retardant polyester composite insulating foil.
Claims (1)
1, hvac duct, hvac duct constitutes by three layers, and it is characterized in that: be followed successively by glass magnesium flaggy [1], polystyrene extrusion molding foam-board thermal insulation layer [2] from the inside to the outside and can roll over external protection [3], each layer sticks with glue to connect and forms.
