Description

Technical Field

[0001] The present invention belongs to the technical field of building thermal insulation panels, and in particular relates to a heat storage type multi-layer composite thermal insulation exterior wall panel. Background Art

[0002] With the increasing requirements for building energy conservation, exterior wall insulation is of vital importance. Traditional exterior wall materials are difficult to balance insulation and other properties. Composite insulation exterior wall panels have come into being. They integrate insulation, heat insulation and other functions. In building exterior wall applications, they can effectively reduce energy consumption, reduce heat transfer, and improve indoor comfort, becoming an indispensable key material for modern building exterior walls.

[0003] At present, the structures and materials of thermal insulation exterior wall panels are rich and varied, among which the method of using phase change materials to store heat has attracted much attention. For example, the phase change all-light concrete energy-saving wall panel disclosed in patent announcement number CN104251034B can not only block heat, but also utilize heat, greatly improving the insulation and energy reduction effect. Especially in areas with large temperature differences between day and night, during the high temperature period during the day, the phase change material absorbs and stores heat from the external environment, and begins to release heat when the temperature drops at night. However, when releasing heat at night, since the outdoor ambient temperature is also low, the heat accumulated by the phase change material during the day will not only be released indoors, but will also inevitably be released outdoors. This causes heat to be wasted in the process of outward loss, reduces heat utilization, and ultimately greatly reduces the use effect. Summary of the Invention

The groove wall of the outer adjustment groove 4 is provided with two connecting grooves 113, and each threaded rod 111 on one side extends to the connecting groove 1 on the same side. 13, each threaded rod 111 on the other side extends to the inside of the inner adjustment groove 8, and the side walls of the outer heat conducting plate 3 and the inner heat conducting plate 7 are threadedly connected to the threaded rod 111 on the same side. A circular groove 114 is provided at the end of each threaded rod 111, and a vent hole 115 is provided on the groove wall of each circular groove 114. Each vent hole 115 is connected to the air cavity 112 on the same side. The installation frame 1 and the outer heat conducting plate 3 and the inner heat conducting plate 7 are sealed to prevent gas from escaping, and the threaded rod 111 can ensure the connection strength between the installation frame 1 and the outer heat conducting plate 3 and the inner heat conducting plate 7, thereby ensuring the structural strength of the entire wall panel.

[0022] A decorative panel 12 is installed on the side wall of the outer heat conducting plate 3 away from the insulation layer 2, and an indicator assembly 13 is installed on the side wall of the decorative panel 12. The indicator assembly 13 includes a pull rod 131, and the pull rod 131 is arranged on one side of one of the connecting grooves 113, and the connecting groove 113 and the side wall of the decorative panel 12 are jointly provided with a circular hole 132.

The water-absorbing color-changing filler 135 can be made of a water-absorbing color-changing material such as color-changing silica gel. By checking the color of the water-absorbing color-changing filler 135, the sealing performance of the wall panel can be quickly judged, thereby inferring the thermal insulation performance of the wall panel.

[0023] One end of the pull rod 131 away from the insulation layer 2 is fixedly connected with a stud 14, and the stud 14 is threadedly connected to the hole wall of the circular hole 132. The stud 14 can ensure the stability of the pull rod 131 and other components.

[0024] Both side walls of the thermal insulation layer 2 are fixedly connected to heat transfer plates 15, and each air guide sleeve 104 passes through the side walls of the two heat transfer plates 15. Frame-type seals 16 are provided between the outer heat conduction plate 3 and the inner heat conduction plate 7 and the side walls of the heat transfer plates 15 on the same side. The frame-type seals 16 cooperate with the heat transfer plates 15 to ensure the sealing between the outer heat conduction plate 3 and the inner heat conduction plate 7 and the thermal insulation layer 2, thereby preventing gas crossflow.

[0025] The operating principle of the present invention is now explained as follows: After the wall panel is installed on the wall of the building, during high temperature periods such as during the day, outdoor heat is conducted to the outer heat conducting plate 3 and each cylinder 51 through the decorative panel 12. As the heat is conducted, the temperature inside the cylinder 51 increases. Under the action of the temperature, the phase change filler 56 filled therein begins to transform from a solid state to a molten state (the phase change filler 56 can be made of paraffin wax, hydrated salt or other fillers. At a temperature of about 30°C, the phase change filler 56 begins to transform from a solid state to a molten state). At this time, the phase change filler 56 transforms into a molten state, so the pressure at the phase change filler 56 increases, thereby causing the pushing piston block 52 to move toward the insulation layer 2. The pushing piston block 52 will push the outer piston plate 101 to move through the push rod 53, and the outer piston plate 101 can push the inner piston plate 102 to move synchronously through the connecting rod 103. When the outer piston plate 101 moves toward the insulation layer 2, The space between the outer piston plate 101 and the bottom of the outer regulating groove 4 increases, thereby generating a negative pressure in the outer regulating groove 4. When the inner piston plate 102 moves away from the thermal insulation layer 2, the inner piston plate 102 squeezes the space inside the inner regulating groove 8, thereby increasing the air pressure inside the inner regulating groove 8. Under the action of the pressure difference, the heat-conducting gas 9 in the inner regulating groove 8 enters the two air cavities 112 through the circular groove 114 and the air vent 115 of the threaded rod 111 on the same side, and enters the connecting groove 113 through the air vent 115 and the circular groove 114 of the threaded rod 111 on the other side. As a result, the heat-conducting gas 9 is replenished into the outer regulating groove 4 through the connecting groove 113, while the heat-insulating gas 6 in the outer regulating groove 4 enters the inner regulating groove 8 through the gas guide sleeve 104 (wherein, the heat-conducting gas 9 is an inert gas with good thermal conductivity, such as helium or neon, and the heat-insulating gas 6 is an inert gas with good thermal resistance, such as krypton or argon). When the outer piston plate 101 contacts the side wall of the heat transfer plate 15 on the same side, the heat from the external environment is transferred to the thermal insulation layer 2 through the decorative panel 12, the outer heat transfer plate 3, the heat transfer gas 9, the outer piston plate 101, and the heat transfer plate 15 near the outside. (The thermal insulation layer 2 is made of a plate material with good heat storage performance, such as a ceramic particle board. The ceramic particle board is made of ceramic particles and a binder. The ceramic particles have a high specific heat capacity and good heat storage performance. This type of plate material can effectively absorb and store heat.) After the heat is transferred to the thermal insulation layer 2, because the insulating gas 6 is between the thermal insulation layer 2 and the inner piston plate 102, the heat from the thermal insulation layer 2 is not easily transferred to the inner heat transfer plate 7. This can reduce the impact of high outdoor temperatures on the indoor environment and reduce heat loss from the thermal insulation layer 2, thereby improving heat storage capacity. As the outdoor temperature drops, the phase change filler 56 gradually changes from liquid to solid, so the pressure at the phase change filler 56 decreases. At this time, under the action of the support spring 55, the piston block 52 starts to move back and reset, pushing the piston block 52 to drive the outer piston plate 101 to move back through the push rod 53, and the inner piston plate 102 moves back synchronously. Therefore, the heat-conducting gas 9 in the outer regulating tank 4 will flow back into the inner regulating tank 8, and the heat-insulating gas 6 in the inner regulating tank 8 will flow back into the outer regulating tank 4. Therefore, when the outdoor temperature drops, the heat previously stored in the insulation layer 2 will be transferred to the inner heat-conducting plate 7 through the inner piston plate 102 and the heat-conducting gas 9, so that the heat is transferred to the room through the inner heat-conducting plate 7, thereby achieving the effect of fully utilizing the heat (wherein, the inner piston plate 102 and the outer piston plate 101 are both made of materials with good thermal conductivity); During use, personnel can regularly unscrew the studs 14 at the decorative panel 12, and pull the mesh 134 out to a proper distance through the studs 14 and the pull rod 131 (to ensure that the inner sealing plug 133 can seal the circular hole 132 to prevent the heat-conducting gas 9 from flowing out). When the sealing of the wall panel fails, the heat-conducting gas 9 will flow out through the sealing failure, and the external water vapor will also enter the wall panel through the sealing failure position. Therefore, when the wall panel fails to seal, the external water vapor will mix with the mesh 13 4 comes into contact with the water-absorbing color-changing filler 135 inside (the water-absorbing color-changing filler 135 can be made of color-changing silica gel particles), causing the water-absorbing color-changing filler 135 to change color. By judging the color of the water-absorbing color-changing filler 135, personnel can quickly determine whether the wall panel has a sealing failure. Since when the seal fails, the heat-conducting gas 9 will flow out, which will to a certain extent affect the thermal insulation performance of the wall panel. Therefore, when the water-absorbing color-changing filler 135 appears, the wall panel can be removed for repair or replacement.

[0026] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
