Therefore, it does not meet the existing demand, and a kind of energy-saving passive curtain wall system is proposed. UTILITY MODEL CONTENTS

[0005] The utility model aims at providing a kind of energy-saving passive curtain wall system to solve the problem that the existing curtain wall system mainly aims at the heat-sealing property between profile and assembly in the above background art, and the heat-sealing property between frame and frame is insufficient, which affects the energy-saving effect of the whole curtain wall system.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical scheme: an energy-saving passive curtain wall system, comprising: first frame body and second frame body, the second frame body is installed on one side of first frame body, first frame body and second frame body are installed with first heat-sealing component consisting of multiple groups of heat insulation strips between them, first frame body and second frame body are also installed with second heat-sealing component consisting of multiple groups of rubber strips between them.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] (1) In this utility model, the thermal insulation strip and polyurethane foam form a multi-cavity structure to reduce the convective heat transfer of air. In addition to heat preservation, the second thermal insulation strip also serves to fix the middle sealing strip and forms a thermal insulation system with the sealing strip. The third thermal insulation strip is a four-cavity thermal insulation strip to reduce the convective heat transfer of air in the cavity. The first, second, third and fourth thermal insulation strips use polyurethane foam, a low thermal resistance material, which has a low thermal conductivity and can effectively reduce heat conduction and heat convection in the cavity.

[0015] (2) In this utility model, three seals are formed between the first frame body and the second frame body by adding sealing strips, overlapping strips and inner glass strips. The sealing strips have a multi-cavity structure, which can reduce the convective heat transfer of air in the cavity. The strips are made of foamed EPDM material with low thermal conductivity, which reduces the heat conduction of the material and improves the heat preservation effect.

[0016] (3) In this utility model, the polyethylene plastic foam has a low heat transfer coefficient. The lower heat transfer coefficient reduces the heat conduction of the profile, and the comb-shaped filling between the glass and the aluminum alloy reduces convective heat transfer, thereby improving the heat insulation performance.

Detailed Implementation

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

The first thermal insulation sealing assembly includes a first thermal insulation strip 4, a second thermal insulation strip 5, a third thermal insulation strip 7, and a fourth thermal insulation strip 8, the surface of which has four... Each cavity is made of polyamide. The first heat insulation strip 4, the second heat insulation strip 5, the third heat insulation strip 7 and the fourth heat insulation strip 8 are all made of polyamide. The second heat insulation sealing assembly includes a sealing strip 6, which is located between the second heat insulation strip 5 and the third heat insulation strip 7. Multiple cavities are opened in the sealing strip 6. The first heat insulation strip 4 and the second heat insulation strip 5 are one group, and the third heat insulation strip 7 and the fourth heat insulation strip 8 are another group. A second polyurethane foam 13 is installed between each group of heat insulation strips. A bolt assembly 3 is installed inside the second frame body 2, and a first polyurethane foam 10 is provided on the outside of the bolt assembly 3.

[0023] The thermal insulation strip and polyurethane foam form a multi-cavity structure to reduce convective heat transfer from the air. In addition to insulation, the second thermal insulation strip 5 also serves to fix the intermediate sealing strip 6, forming a thermal insulation system with the sealing strip 6. The third thermal insulation strip 7 is a four-cavity thermal insulation strip used to reduce convective heat transfer from the air inside the cavity. The first thermal insulation strip 4, the second thermal insulation strip 5, the third thermal insulation strip 7, and the fourth thermal insulation strip 8 use polyurethane foam, a low thermal resistance material with a thermal conductivity of 0.022 W / (m·K), which can effectively reduce heat conduction and heat convection within the cavity.

[0024] Please see Figure 1 The second thermal insulation sealing assembly also includes an overlap strip 11 installed at the contact end of the top of the first frame 1 and the second frame 2, and an inner glass sealant strip 12 for sealing the glass. The sealing strip 6, the overlap strip 11, and the inner glass sealant strip 12 are all made of EPDM. The first frame 1 and the second frame 2 are sealed with three layers by adding the sealing strip 6, the overlap strip 11, and the inner glass sealant strip 12. The sealing strip 6 has a multi-cavity structure, which can reduce the convective heat transfer of air in the cavity. The strip is made of foamed EPDM material with low thermal conductivity, which reduces the heat conduction of the material and improves the thermal insulation effect.

[0025] Please see Figure 1 A polyethylene foam 9 is installed on one side of the fourth thermal insulation strip 8. The polyethylene foam 9 has a comb-like structure and is filled between the glass and the aluminum alloy profile. The heat transfer coefficient of the polyethylene foam 9 is as low as 0.047W / (m·K). The low heat transfer coefficient reduces the heat conduction of the profile, and the comb-like structure between the glass and the aluminum alloy reduces convective heat transfer, thereby improving the thermal insulation performance.
