[0016] Compared with the prior art, the present invention has the following characteristics and beneficial effects.

[0017] 1. In order to achieve the overall integrity of the facade visual effect without being destroyed by the openable sashes for ventilation, the present invention cancels the ventilation opening device on the glass. The ventilation effect is achieved by hiding the ventilation opening system on the inner side of the ventilation curtain wall system, and setting holes on the exterior panels of the curtain wall at the corresponding windows. The window keel of the present invention adopts a steel keel, and the window frame adopts a composite structural system composed of aluminum alloy profiles, insulation strips and sealing strips. At the same time, the composite vacuum insulation partition and the openable sash adopt fluorocarbon sprayed aluminum alloy plates, high insulation performance vacuum insulation panels and insulation rock wool to evenly form an excellent performance insulation and ventilation curtain wall system. When the openable sash is opened, ventilation can be carried out well; when closed, heat transfer caused by air convection can be effectively avoided. The invention effectively solves the technical problems of the opening device on the traditional curtain wall system that destroys the overall aesthetics, poor visual effects, weak insulation performance and complex structure.

[0018] 2. The composite vacuum insulation partition and openable window sash in the present invention encapsulate the vacuum insulation board and the rock wool insulation board between two layers of aluminum plates. The thickness is ultra-thin and equipped with an aluminum alloy window frame, a window keel and a window handle. The hinges are hidden and the edges are designed with pressed edges all around. After opening, it does not affect the integrity of the facade and is safer.

[0019] 3. The aluminum alloy insulation window system of the present invention is optimized on the basis of abandoning the visual shortcomings of the traditional insulation window, such as the wide exposed frame and the exposed hinges. The combination relationship with the interior is fully considered to carry out the design of details such as concealed opening frame sash, hidden hinges and hidden seams at the intersection with the interior. The sealing adopts a sealing strip and sealant composite sealing structure system, which is beautiful and reliable. At the same time, in order to ensure the ventilation area, the present invention minimizes the thickness of the openable window sash, and adopts a vacuum insulation panel with excellent thermal insulation performance inside the openable window sash. The vacuum insulation panel (VIP panel) is a kind of vacuum insulation material, which is composed of a filling core material and a vacuum protective surface layer. It effectively avoids heat transfer caused by air convection, so the thermal conductivity can be greatly reduced, which can reach 0.002-0.004w / mk, which is 1 / 10 of the thermal conductivity of traditional insulation materials.

[0020] 4. The hidden aluminum curtain wall ultra-thin composite vacuum insulation ventilation opening system of the present invention realizes the purpose of aesthetic and functional integrated design. The hidden opening device integrates the openable window sash between the window stile and the top edge of the window frame, and adopts the hole design of the external decorative panel to realize the complete hiding of the facade of the opening component. The facade only retains the rectangular cells surrounded by horizontal and vertical decorative strips, and the visual permeability is improved by 40%, avoiding the damage of the traditional exposed blinds or opening sashes to the building facade. At the same time, from the indoor perspective, the hinges, pressing edges, etc. are hidden in the outer cladding to form visual continuity. It is measured that the human eye cannot identify the opening device at 10 meters away, achieving a "traceless" facade effect. In addition, the total thickness of the ultra-thin composite structure composite vacuum insulation partition and the openable window sash of the present invention is controlled at 70-80mm (traditional systems are generally ≥120mm), which not only achieves the energy-saving efficiency of the curtain wall, but also saves about the building's usable area.

[0021] 5. The present invention realizes high thermal insulation, high airtightness and high aesthetic performance of the curtain wall system in ultra-thin thickness through systematic innovation of vacuum insulation technology, modular assembly and concealed opening and closing design, and completely solves the industry pain points of traditional curtain wall opening devices that damage the integrity of the facade, have poor thermal performance and high maintenance costs, and provides a new technical solution for ultra-low energy consumption buildings, with significant economic and social benefits.
