Description

Technical Field

[0001] The present invention belongs to the field of building technology, and particularly relates to an energy-saving exterior wall for high-rise buildings with a unidirectional heat release function and a method thereof. Background Art

[0002] During the construction of buildings, sound insulation boards, thermal insulation boards, fireproof boards and other structures are arranged in a certain order to form an exterior wall structure, so as to achieve heat insulation, sound insulation and fire prevention of the house. The fireproof exterior wall is a non-combustible wall that prevents the spread of fire to adjacent areas and has a fire resistance limit of not less than 3 hours. It is an important separating component for dividing fire compartments or preventing the spread of fire between buildings. It can effectively limit the fire within a certain space in the initial stage of the fire and during the fire extinguishing process, and block the spread of the fire from one side of the fire wall to the other side, which plays an important role in reducing fire losses.

[0003] Existing thermal insulation and fireproof materials generally only have the effects of thermal insulation and fire prevention, but have no unidirectional heat transfer effect. They cannot effectively utilize the solar energy irradiated by the sun during the day to store heat inside the wall, and then unidirectionally transfer the heat inside the wall to the room at night. Moreover, the installation of existing thermal insulation and fireproof materials only fixes two thermal insulation and fireproof boards by installation strips, and this method has a poor fixing effect.

[0019] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0020] 1.

[0029] Embodiment 1

[0030] Please refer to Figure 1 、 Figure 3 、 Figure 4 and Figure 5 As shown, the present application provides an energy-saving exterior wall for high-rise buildings with a one-way heat release function, including an outer wall 1. A cavity 101 is vertically arranged inside the outer wall 1. A reinforcement cage framework 102 is installed in the cavity 101, and concrete is poured into the cavity 101. In order to further enhance the overall structural strength of the upper and lower outer walls 1, after the upper and lower parts are assembled, the reinforcement cage framework 102 is inserted into the cavity, and the structural strength of the wall is ensured by pouring concrete.

[0031] A phase change heat storage plate 2 is installed in the cavity 101. A heat collecting plate 6 is connected to the outside of the outer wall 1 through a protection component. A unidirectional heat absorption structure is arranged on the heat collecting plate 6. The unidirectional heat absorption structure penetrates through the protection component and is communicated with the phase change heat storage plate 2. A heat release plate 7 is installed on the outside of the outer wall 1. The heat release plate 7 and the phase change heat storage plate 2 are connected through a unidirectional heat release structure. During the day, the heat collecting plate 6 absorbs heat, causing the temperature of the heat conduction sleeve 8 to rise. As a result, the length of the thermal expansion and contraction telescopic body 9 inside it elongates. Then, the thermal expansion and contraction telescopic body 9 drives the heat transfer body 10 to move away from the heat collecting plate 6. At the same time, it drives the connecting plate one 16, the connecting plate two 15, and the connecting rod 17 to move away from the heat collecting plate 6 until the heat transfer body 10 fits on the heat conduction outer frame body 21, achieving unidirectional heat absorption. At the same time, the heat release column 18 is separated from the phase change heat storage plate 2, and the heat transfer route is disconnected. At night, due to the low outdoor temperature, the heat collecting plate 6 loses a large amount of heat. The length of the thermal expansion and contraction telescopic body 9 shortens, the heat transfer body 10 is separated from the phase change heat storage plate 2 to disconnect the heat transfer route. At the same time, through the connecting rod 17, the heat release column 18 fits on the phase change heat storage plate 2, and then the heat release route is connected, achieving the heat release effect indoors.

[0032] The protection component includes an expanded foam board 3 installed on the outside of the outer wall 1. A fireproof fiber board 4 is installed on the outside of the expanded foam board 3. An exterior decoration board 5 is installed on the outside of the fireproof fiber board 4. The heat collecting plate 6 is embedded in the exterior decoration board 5. The outer side surface of the heat collecting plate 6 is flush with the outer side surface of the exterior decoration board 5.

[0033] The phase change heat storage plate 2 includes a heat conduction outer frame body 201 and a phase change heat storage material 202 filled inside the heat conduction outer frame body 201.

The thermal expansion and contraction telescopic body 9 is fixed on the heat collecting plate 6, and the thermal expansion and contraction telescopic body 9 is located between the heat transfer body 10 and the heat collecting plate 6. The heat transfer body 10 is in contact with the heat conduction sleeve 8, and the inner wall of the heat transfer body 10 and the heat conduction sleeve 8 always contact to form a heat conduction route.

[0035] The one-way heat release structure includes an inserted sleeve 11 and a heat release pipe 12. One end of the inserted sleeve 11 passes through the phase change heat storage plate 2 from the expansion foam board 3 into the outer wall 1. Installation frames one 13 and two 14 are respectively installed at both ends of the inserted sleeve 11. A connecting plate one 16 is slidably fitted in the installation frame one 13, and a connecting plate two 15 is slidably fitted in the installation frame two 14. A connecting rod 17 is slidably fitted in the inserted sleeve 11. Both ends of the connecting rod 17 are fixedly connected to the connecting plate one 16 and the connecting plate two 15 respectively. The installation frame one 13 is embedded in the expansion foam board 3, and the installation frame two 14 is embedded in the outer wall 1. The heat release pipe 12 is fixedly installed on the side of the heat release plate 7 facing the outer wall 1 and does not contact the phase change heat storage plate 2. A heat release column 18 is installed inside the heat release pipe 12. The heat release column 18 is slidably fitted in the heat release pipe 12 and always contacts the heat release pipe 12 to form a heat release path. The connecting plate one 16 is fixedly connected to the heat transfer body 10, and the connecting plate two 15 is fixedly connected to the heat release column 18.

[0036] The present invention also discloses an energy-saving method for high-rise buildings with one-way heat release function, which specifically includes the following steps:

[0037] Step 1: During the day, the heat collecting plate 6 absorbs heat, causing the temperature of the heat conducting sleeve 8 to rise. As a result, the length of the thermal expansion and contraction body 9 inside increases, and then the thermal expansion and contraction body 9 drives the heat transfer body 10 to move away from the heat collecting plate 6. At the same time, it drives the connecting plate one 16, the connecting plate two 15, and the connecting rod 17 to move away from the heat collecting plate 6 until the heat transfer body 10 fits on the heat conducting outer frame 21, achieving one-way heat absorption. At the same time, the heat release column 18 disengages from the phase change heat storage plate 2, and the heat transfer path is disconnected.

[0038] Step 2: At night, the heat collecting plate 6 loses a large amount of heat. The length of the thermal expansion and contraction body 9 shortens, and the heat transfer body 10 disengages from the phase change heat storage plate 2 to disconnect the heat transfer path. At the same time, through the connecting rod 17, the heat release column 18 fits on the phase change heat storage plate 2, thereby connecting the heat release path and achieving the heat release effect on the indoor side.
