Detailed ways

The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

An assembled breathing building exterior wall with adjustable heat transfer capacity according to the present invention, as shown in Figure 1, includes an indoor end wall panel 1 and an outdoor end wall panel 3 oppositely arranged, and an indoor end wall panel 1 and an outdoor end wall panel 3 A sandwich wall 2 is arranged between them, and the opposite ends of the sandwich wall 2 are fixedly connected with a pushing mechanism, and the wall body of the sandwich wall 2 is provided with a plurality of first sockets 22, and the wall surface of the sandwich wall 2 is fixedly connected with a first convex plate 21. The surface of the outdoor end wall panel 3 is provided with a number of second sockets 31, the second sockets 31 are matched with the first convex plate 21, and the surface of the outdoor end wall panel 3 is fixedly connected with a second convex plate 33, The second protruding plate 33 matches the first insertion hole 22 , and the first protruding plate 21 and the second protruding plate 33 are oppositely arranged.

As shown in FIGS. 2-3 , the pushing mechanism includes slide rails 23 fixedly connected to both ends of the interlayer wall 2 .

The number of slide rails 23 is set to four, and the four slide rails 23 are evenly distributed at both ends of the interlayer wall 2 .

The slide rail 23 includes a slide block 2301 fixedly connected to the interlayer wall 2 , and a slideway 2302 is slidably connected to the side of the slide block 2301 away from the interlayer wall 2 .

As shown in Figure 4, the slideways 2302 at both ends of the sandwich wall 2 are fixedly connected to the upper floor 41 and the lower floor respectively. The interlayer wall 2 forms a second cavity 6 with the outdoor end wall panel 3, the upper end floor 41 and the lower end floor 42, and the upper and lower ends of the second cavity 6 are provided with HVAC pipes 7, and the interlayer wall 2 and the indoor end wall panel 1, the upper floor 41 and the lower floor 42 form the first cavity 5.

As shown in Figure 5-6, the board surface of the outdoor end wall panel 3 is also provided with a number of ventilation holes 32, the number of the ventilation holes 32 corresponds to the number of the second jacks 31, and the cross section of the ventilation holes 32 is set as "L" shape structure, one end of the air hole 32 is arranged near the side of the movable plate 24, and the other end of the air hole 32 communicates with the hole body of the second insertion hole 31.

The length of the first protruding plate 21 is not less than the length of the second protruding plate 33 . Guaranteed that when the first convex plate 21 is inserted into the second insertion hole 31 and does not have any blockage to the air hole 32, the second convex plate 33 will not be inserted into the first insertion hole 22; When the inside of 31 is completely blocked, the second convex plate 33 should also completely block the first jack 22.

As shown in Figures 7-9, when the outdoor temperature is lower than the indoor temperature (winter), the position of the movable plate 24 can be adjusted so that the second jack 31 is blocked by the first convex plate 21, and the first jack 22 Blocked by the second convex plate 33, the space between the movable panel 24 and the outdoor end wall panel 3 will form a second cavity 6, and the second cavity 6 will cooperate with the movable panel 24 and the outdoor end wall panel 3, so that the exterior of the building The wall is in a state of strong heat insulation, and it is difficult for the heat in the room to transfer to the outside.

In hot summer and when the indoor temperature is not high, the above principle is also applicable, and it is difficult for outdoor heat to enter the room along the outer wall of the building.

When the indoor temperature is high, that is, when the heat storage in the first cavity 5 is large, the heating and ventilation pipe 7 can be used to form air circulation from bottom to top, as shown in the airflow direction of FIG. 8 . The heating and ventilation pipe 7 cooperates with the heating and ventilation equipment to form a bottom-up air flow and negative pressure in the second cavity 6 at the same time. With the air circulation, the hot air in the first cavity 5 enters along the first socket 22 The second cavity 6, the hot air in the second cavity 6 will be further exhausted by the heating and ventilation pipe 7 in cooperation with the heating and ventilation equipment. During this process, the heat in the first cavity 5 will be taken away, reducing the indoor cooling load. In this process, the second socket 31 needs to be in an open state. Although hot air enters the second socket 31, it will reduce the air intake load of the HVAC equipment, and the heat entering the second cavity 6 will eventually be absorbed. Therefore, the hot air entering the second socket 31 will not increase the cooling load of the building, but will reduce the cooling load of the building. This process is a case where the second jack 31 and the first jack 22 are all opened.

When summer, when it was raining outdoors, only open the air vent 32, that is, the first convex plate 21 only blocks the second jack 31 part, (only open the air vent 32 when it rains, the second jack 31 can not be opened, otherwise the rainwater will enter the second cavity 6 and damage the equipment parts, so the vent hole 32 is arranged above the second jack 31 to prevent rainwater from seeping in), at this time, the cold air flow outside will enter the second cavity 6 from the vent hole 32, and then Then enter the first cavity 5 from the first insertion hole 22 to form heat exchange in the first cavity 5, thereby reducing the indoor cooling load.

When the first convex plate 21 is inserted into the second insertion hole 31 and does not have any blockage to the air hole 32, the second convex plate 33 will not be inserted into the first insertion hole 22; When the inside is completely blocked, the second convex plate 33 should also completely block the first insertion hole 22 .

When the indoor temperature is lower than the outdoor temperature, the position of the movable plate 24 can be adjusted so that the first convex plate 21 withdraws from the second jack 31, and the second convex plate 33 withdraws from the first jack 22 at the same time. The convex plate 33 and the second socket 31 will greatly weaken the heat insulation of the outer wall of the application, and the outdoor heat will enter the first cavity 5 along the outdoor end wall panel 3, the second cavity 6, and the movable plate 24, This in turn allows heat to flow into the interior, reducing the building's thermal load.

The first convex plate 21 and the movable plate 24 are made of light and thermally inert plates, autoclaved aerated concrete.

The outdoor end wall panel 3 and the second raised panel 33 are made of plates with strong thermal inertia, autoclaved aerated concrete.

The arrangement of the first convex plate 21 on the movable plate 24 will be carried out in conjunction with the overall setting of the building facade, and the outer surface of the first convex plate 21 close to the outdoor end wall panel 3 can be selected with special colors and patterns. In the end, a certain facade of the building can rely on the first convex plate 21 to display a special pattern, increasing the beauty and richness of the building.

The indoor end wall panel 1 is made of materials with strong thermal conductivity, such as wood and aluminum alloy plates. The role of the indoor end maintenance wall panel 1 is to isolate the interlayer wall 2 and prevent the interlayer wall 2 from being directly interfered by the outside during use. At the same time, the indoor end wall panel 1 is made of a material with strong thermal conductivity, which is conducive to the temperature exchange between the indoor temperature and the air in the first cavity 5 through the indoor end wall panel 1 . In addition, the indoor end wall panel 1 can take into account the aesthetics of the interior at the same time, and the use of special patterns has the effect of increasing the aesthetics of the interior. Finally, the maintenance wall panel 1 at the indoor end is installed detachably, so that it is convenient to disassemble the maintenance wall panel 1 at the indoor end later for maintenance of the interlayer wall 2 .
