Problems solved by technology

If the heat transfer coefficient is designed too large, although the heat conducted from the indoor air to the outside through the wall at night is increased, the heat conducted to the room through the wall during the day is also increased.
Therefore, the wall with a fixed heat transfer coefficient cannot make full use of the difference in temperature between day and night to achieve the purpose of reducing air conditioning energy consumption.
In the prior art, there is no building wall technology that can automatically adjust the heat transfer coefficient according to the outdoor temperature.

Embodiment 1

[0028] as attached figure 1 As shown, the wall body with automatic adjustment of heat transfer coefficient includes a surface layer 1, a thermal resistance layer 2, a load-bearing layer 3 and a surface layer 4, each layer is stacked in sequence, and a The heat variable resistance layer 2 is also provided with a surface layer 4 on the inner surface of the load-bearing layer 3 . The variable thermal resistance layer 2 includes several bimetallic sheets 5 and several thermally conductive substrates 6, each bimetallic sheet 5 and a corresponding thermally conductive substrate 6 constitute a conductive thermal bridge between the surface layer 1 and the load-bearing layer 3, along the wall A number of parallel thermal conduction bridges are established between the surface layer 1 and the load-bearing layer 3 in the height direction of the body. For each conduction heat bridge, one end of the heat-conducting matrix 6 is fixed on the surface of the load-bearing layer facing the surfa...

Embodiment 2

[0030] The main difference between Example 2 and Example 1 lies in the variable thermal resistance layer. In Example 2, the thermally conductive substrate in Example 1 is replaced by a bimetallic sheet. Other structural settings are the same, as shown in the attached figure 2 As shown, the variable thermal resistance layer 2 includes several bimetallic strips 7 and several bimetallic strips 8, and a corresponding group of bimetallic strips constitutes a conduction heat bridge between the surface layer 1 and the load-bearing layer 3, along the wall height direction Several groups of conduction heat bridges are established between the surface layer 1 and the load-bearing layer 3 . For each conduction heat bridge, one end of the bimetallic strip 7 is fixed on the surface of the load-bearing layer, one end of the bimetallic strip 8 is fixed on the surface of the surface layer 1, and the bimetallic strip 7 is fixed on the surface of the surface layer. The other end is freely lappe...

Embodiment 3

[0032] The main difference between embodiment 3 and embodiment 1 is that in embodiment 3, a round-headed bimetal sheet and a heat conduction plate are used in the variable thermal resistance layer, and other structural settings are the same, as shown in the attached image 3 As shown, the variable thermal resistance layer arranged between the surface layer 1 and the load-bearing layer 3 includes several round-headed bimetallic sheets 9 and a heat conducting plate 10, one end of the round-headed bimetallic sheet 9 is linear, and the other end Bent into a circle, the straight end of the round head bimetal 9 is fixed on the surface of the surface layer 1 facing the load-bearing layer, and the heat conducting plate 10 is arranged along the entire surface of the load-bearing layer facing the surface layer 1, and is fixed on the surface of the load-bearing layer. on the entire surface. In a normal state, the circular curved end of the round-headed bimetal 9 abuts against the surface...

Abstract

The present invention proposes a wall body with automatic adjustment of heat transfer coefficient, comprising: a surface layer, a variable thermal resistance layer and a load-bearing layer, the variable thermal resistance layer is arranged between the surface layer and the load-bearing layer, and the variable thermal resistance layer The layer includes a bimetal sheet, which directly or indirectly contacts the surface layer and the load-bearing layer in a cold state, and establishes a conductive thermal bridge between the surface layer and the load-bearing layer to increase the heat transfer coefficient of the wall , in the hot state, the bimetal sheet is bent and deformed and separated from the surface layer and / or load-bearing layer, interrupting the conduction heat bridge between the surface layer and the load-bearing layer, and reducing the heat transfer coefficient of the wall . The wall body with automatic adjustment of the heat transfer coefficient of the present invention can not only reduce the heat transmitted from the outdoors to the indoors during the day in summer, but also make full use of the outdoor cold source at night to cool down the indoor air, so as to save the energy consumption of the air conditioner.

Description

technical field [0001] The invention relates to the technical field of environmental protection walls, in particular to a wall with automatic adjustment of heat transfer coefficient. Background technique [0002] The exterior wall of the building is the interface between the interior space and the exterior space of the building. The heat exchange between the interior space of the building and the exterior space is realized through the intermediary of the wall. Therefore, the heat transfer coefficient of the wall has a great influence on the building energy consumption. The greater the heat transfer coefficient, the more heat is conducted through the wall. The lower the heat transfer coefficient, the less heat is conducted through the wall. In summer, when the outdoor temperature is too high during the day, in order to reduce the energy consumption of the air conditioner, the heat transferred into the room through the wall should be reduced, so the smaller the heat transfe...
