Heat insulating type sun-shading energy saving device

Abstract

The invention relates to a casement window sun-shading device and particularly discloses a heat insulating type sun-shading energy saving device which comprises a hollow glass body, a plurality of shutters arranged in parallel, and a driving device used to drive the shutters to overturn. The hollow part inside the hollow glass body forms a sealed cavity in which the shutters are installed; high-reflectivity coatings and low-reflectivity coatings are respectively arranged on the front sides and the back sides of the shutters; and a low reflectivity coating film is arranged on the wall of the side of the sealed cavity, which faces the interior of a house. The heat insulating type sun-shading energy saving device not only solves the problem of dust stratification but also solves the problem of secondary heat transmission while shading the sun, so the heat insulation effect of the heat insulating type sun-shading energy saving device is better.

Description

technical field [0001] The invention relates to a glass window sunshade device, in particular to a heat-insulating sunshade energy-saving device. Background technique [0002] Buildings are exposed to different outdoor weather conditions throughout the year, usually hot in summer and cold in winter. However, people hope that the indoor temperature can be warm in winter and cool in summer. If you rely entirely on air-conditioning or heating systems, it will consume a lot of energy. Therefore, it is very necessary to construct energy-saving buildings, and the shading system plays a vital role in existing energy-saving buildings. [0003] The current mainstream shading systems are mainly divided into external shading systems, internal shading systems and breathing curtain wall shading systems. These three shading systems have their own advantages and disadvantages: [0004] Among them, the external shading system is a better solution from the thermal point of view, completely...

Problems solved by technology

[0012] At the same time, the utility model patent with the Chinese notification number CN 2775270Y discloses a hollow glass louver, which is mainly composed of a hollow glass window and a venetian blind. The venetian blind is placed in the hollow glass interlayer. The heat will still be transferred to the room and affect the insulation effect

[0013] Another example is a utility model patent with the Chinese notification number CN 201196009Y disclosing a high-efficiency energy-saving window, which mainly includes a window frame, a window glass, a venetian roller blind and its adjustment device, an external sunshade and its telescopic device, and its heat transmission is mainly It is controlled by the material change of the window frame. There is a venetian blind installed between two layers of ordinary glass in the window frame. The venetian blind still generates heat after absorbing sunlight, and part of the heat will diffuse to the room to affect the heat insulation effect.

[0014] Another example is that the invention patent of CN 101358505A with the Chinese Publication No. discloses a kind of glass window and curtain wall which has sunshade function itself in summer and can reflect sunlight into the room in winter. The outer layer is provided with a movable window, which can form a certain angle with the window or the main body of the curtain wall after being moved. This invention has a simple structure and is easy to produce and use. When the sun's rays pass through the window, the window itself will absorb the light and generate heat. When the heat diffuses into the room, it will inevitably affect the heat insulation effect of the window itself.

[0015] To sum up, the existing shading devices are mainly used for shading, and there are still problems of secondary heat transfer of the shading device itself, and dust accumulation affecting the heat insulation effect
