Abstract
The utility model relates to a reflective insulation structure of an air space, which is characterized in that a reflective material is an aluminum box with the reflectivity Epsilon smaller than or equal to 0.12; the thickness of the air space is 6-12 mm; when an air space supporting material is a honeycomb, the actual material thermal coefficient Lambda P is smaller than or equal to 0.03-0.222 (w/m. DEG C), the orthohexagonal side length Lambda is equal to 6-9 mm, the thickness b is smaller than or equal to 0.6 mm and the volumetric ratio Beta of air in the air space is larger than or equal to 0.97; and when the air space supporting material is light material with low thermal coefficient, the Lambda P is smaller than or equal to 0.033 (w/m. DEG C). Both the honeycomb and the extra-fine glass wool with low thermal coefficient are adopted as the support material of the air space, and the aluminum box with low radiativity is used as the reflective material, so the price is cheaper compared with polyurethane foams, thereby the utility model guarantees the comparative insulation performance and saves the manufacture cost as well.
Description
Technical field
The utility model relates to a kind of interbed heat insulating construction, is specifically related to a kind of structure of reflective insulation structure of interbed.
Background technique
Heat-insulation material at solar water heater water tank and refrigerator etc. mainly forms in the polyurethane foam mode, yet this foam process has used the chloro-fluoro-hydrocarbons material harmful to atmosphere, technology after the improvement also has carries out floride-free foaming, right cost can increase to some extent, though polyurethane foam insulation thermal insulation is best in existing heat-insulation material, but its operating temperature is lower, material price is also going up, in order to make heat-insulating property can be better than the polyurethane foam heat-insulating property, have the nano-hole silica thermoinsulation material to be pushed out in succession, its performance is excellent really, but cost is higher, and for the insulation of low-temperature water heating device and refrigerator, its performance is some surplus again.
The model utility content
The utility model purpose is that the notion according to air space and reflective insulation material structure provides a kind of concrete material behavior, mode of structure and size that is suitable for solar water heater, refrigerator and other operating temperatures less than 150 ℃ the adiabatic needs of insulation, and its cost performance is approached and is higher than polyurethane foam.
The utility model is achieved through the following technical solutions:
A kind of air space reflective insulation structure alternately constitutes the reflective insulation interbed by blocking materials honeycomb or glass wool and aluminium foil, and the interbed outermost surface is an aluminium foil; Reflectivity ε≤0.12 of aluminium case, layer thickness is 6-12mm therebetween, when the interbed blocking materials is honeycomb, material thermal conductivity λ in fact
P≤ 0.03-0.222 (w/m. ℃), its positive hexagonal length of side λ=6-9mm, its thickness b≤0.6mm, air occupies volume ratio beta 〉=0.97 in the interbed, and the interbed blocking materials is a glass wool, its λ
P≤ 0.033 (w/m. ℃).
A kind of air space reflective insulation structure, described aluminium foil is low emission aluminium foil.
A kind of air space reflective insulation structure, described glass wool are super glass wool.
Adopted the blocking materials of honeycomb and low thermal conductivity material super glass wool air space, with low emission aluminium foil is reflecting material, can make this model utility heat insulating construction performance can near or surpass the polyurethane foam thermoinsulation material, adopt the blocking materials of honeycomb and low thermal conductivity material super glass wool air space simultaneously, with low emission aluminium foil is reflecting material, the polyurethane foam thermoinsulation material of comparing is more cheap, thereby taken care of yourself insulation capacity suitable in, saved manufacture cost.
Description of drawings
Fig. 1 is the generalized section of the honeycomb heat insulating construction of a water tank.
Fig. 2 is the heat insulating construction sectional view of the multiple aluminium super glass wool of collector in the heat collector header.
Embodiment
Referring to Fig. 1, between water tank liner 1 and tank shell 2, alternately constitute the reflective insulation interbed by honeycomb 4 and low emission aluminium foil 3, the interbed outermost surface is low emission aluminium foil 3.Adopting honeycomb 4 as blocking materials, is reflecting material with low emission aluminium foil 3, and the polyurethane foam thermoinsulation material of comparing is more cheap, thus taken care of yourself insulation capacity suitable in, saved manufacture cost.
Referring to Fig. 2, between heat collector header collector 5 and header shell 6, alternately constitute the reflective insulation interbed by super glass wool 7 and low emission aluminium foil 3, the interbed outermost surface is low emission aluminium foil 3.Adopting super glass wool 7 as blocking materials, is reflecting material with low emission aluminium foil 3, and the polyurethane foam thermoinsulation material of comparing is more cheap, thus taken care of yourself insulation capacity suitable in, saved manufacture cost.
