Description

Technical Field

[0001] This application relates to the technical field of building thermal insulation and energy conservation, and specifically relates to an external wall thermal insulation system and its control method. Background Art

[0002] An external wall thermal insulation system refers to an engineering practice that uses a certain fixing method (adhesion, mechanical anchoring, adhesion + mechanical anchoring, spraying, casting, etc.) to fix a heat-insulating material with a relatively low thermal conductivity to the building wall as a whole, increasing the average thermal resistance of the wall, thereby achieving the effect of heat preservation or heat insulation.

[0003] In the Chinese patent document with the publication number CN217812057U, an assembled external wall external thermal insulation system is disclosed, and specifically discloses a thermal insulation board assembly, at least one set of wall-hanging components and external wall horizontal keels. Among them, the external wall horizontal keel is fixedly connected to the wall; the thermal insulation board assembly includes a panel, at least two vertical keels of the board member, at least one horizontal keel of the board member and at least two keel connectors. Among them, each vertical keel of the board member is fixedly connected to the panel through a connecting nail; each set of wall-hanging components includes a sub-connector and a mother-connector; the thermal insulation board assembly and the external wall are mutually buckled through the sub-connector and the mother-connector to achieve rapid installation, simplifying the on-site process and the installation process. Moreover, the thermal insulation board assembly and the panel can be replaced separately; the three-dimensional adjustment of the thermal insulation board assembly in the longitudinal, transverse and vertical directions is realized through the wall-hanging components, ensuring the installation accuracy of the thermal insulation board assembly; by using a connecting nail to penetrate from the front of the panel to the back of the panel and fixedly connecting the panel and the vertical keel of the board member, the problems that may be caused when using back bolts are avoided.

[0004] However, in the above patent, the heat preservation effect of the external wall is only achieved by relying on the heat insulation characteristics of the thermal insulation board assembly itself, and the overall heat preservation effect is still in a relatively poor state. Moreover, there are relatively high requirements for the installation flatness of the thermal insulation board assembly, increasing the installation difficulty. Summary of the Invention

[0005] In order to overcome the deficiencies of the prior art, this application provides an external wall thermal insulation system and its control method.

[0006] This application is implemented by adopting the following technical solutions: An external wall thermal insulation system is provided on the surface of a wall, including a frame assembly and a plurality of thermal insulation covers fixed on the frame assembly. A heat conduction assembly is arranged inside the thermal insulation cover, the heat conduction assembly is attached to the surface of the wall, and a flowing heat conduction medium is arranged inside the heat conduction assembly. The heat conduction medium is used to transfer heat to the surface of the wall or absorb the heat on the surface of the wall.

[0007] By adopting the above technical solution, the heat preservation cover plate plays a primary role in heat insulation and preservation for the wall. When in an environment with a relatively low external temperature such as in winter, a heat-conducting medium with a relatively high temperature can be conveyed into the heat-conducting component, so as to convey the heat in the heat-conducting medium to the surface of the wall, reduce the heat loss on the surface of the wall, and play a heat preservation effect of assisting in temperature rise. When in an environment with a relatively high external temperature such as in summer, a heat-conducting medium with a relatively low temperature can be conveyed into the heat-conducting component, so as to absorb the heat on the surface of the wall into the heat-conducting medium, reduce the significant increase in the surface temperature of the wall caused by solar radiation, and play a heat preservation effect of assisting in temperature reduction, effectively improving the heat preservation effect on the wall of the building.

[0008] Optionally, the frame assembly includes a frame body and a fixed base. The fixed base is detachably arranged on the surface of the wall. The frame body is fixed by at least four fixed bases. Ear plates are arranged on the side wall of the heat preservation cover plate, and the ear plates and the frame assembly are fixed by bolts.

[0009] By adopting the above technical solution, the fixed base plays a role in fixing the frame body. In this way, after the frame body is reliably fixed by the fixed base, the heat preservation cover plate can be placed on the frame body, and then the ear plates and the frame body are locked by bolts, so as to realize the reliable and rapid installation of the heat preservation cover plate.

[0010] Optionally, the heat preservation cover plate is in the shape of a square cover, and there is a gap between two adjacent heat preservation cover plates. The heat-conducting component is arranged inside the heat preservation cover plate and is separated from the heat preservation cover plate.

[0011] By adopting the above technical solution, it is ensured that there is enough space between the heat preservation cover plate and the wall for the installation of the heat-conducting component. At the same time, after the heat preservation cover plate is installed, the gap can be filled with sealant, so that a relatively airtight space can be formed between several heat preservation cover plates and the wall, further improving the heat preservation effect on the wall.

[0012] Optionally, a first water collecting pipe is arranged at the upper part of the frame assembly, a second water collecting pipe is arranged at the lower part of the frame assembly, and several heat-conducting component modules are arranged between the first water collecting pipe and the second water collecting pipe. The heat-conducting component module is composed of several heat-conducting components in the same column;

[0013] The upper end of the heat-conducting component module is communicated with the first water collecting pipe through a first branch pipe, and the lower end of the heat-conducting component module is communicated with the second water collecting pipe through a second branch pipe.

[0014] By adopting the above technical solution, under the connection action of the first branch pipe and the second branch pipe, the heat-conducting medium in the first water collecting pipe can flow evenly into the heat-conducting component module and flow back to the second water collecting pipe in a concentrated manner. At the same time, the heat-conducting medium in the second water collecting pipe can also flow back into the heat-conducting component module, thereby realizing reliable and circulating flow of the heat-conducting medium in the heat-conducting component module and improving the thermal insulation effect of the wall.

[0015] Optionally, the first water collecting pipe is provided with a first water inlet pipe and a first water outlet pipe, and the second water collecting pipe is provided with a second water inlet pipe and a second water outlet pipe;

[0016] The first water inlet pipe is provided with a first water inlet valve, and the second water inlet pipe is provided with a second water inlet valve;

[0017] The first water outlet pipe is provided with a first water outlet valve, and the second water outlet pipe is provided with a second water outlet valve;

[0018] A first water tank is provided above the wall, and a second water tank is provided below the wall. The first water inlet pipe and the second water outlet pipe are both connected to the first water tank, and the second water inlet pipe and the first water outlet pipe are both connected to the second water tank.

[0019] By adopting the above technical solution, the first water storage tank is used to store a heat-conducting medium with a higher temperature, and the second water storage tank is used to store a heat-conducting medium with a lower temperature. By controlling the opening and closing states of the first water inlet valve, the first water outlet valve, the second water inlet valve, and the second water outlet valve, the heat-conducting medium circulates between the first water storage tank and the heat-conducting component or circulates between the second water storage tank and the heat-conducting component, thereby achieving effective insulation of the wall in environments with different temperatures.

[0020] Optionally, the first water inlet valve and the second water outlet valve are in the same opening and closing state, the second water inlet valve and the first water outlet valve are in the same opening and closing state, and the first water inlet valve and the second water inlet valve are in opposite opening and closing states.

[0021] By adopting the above technical solution, the temperature of the heat-conducting medium flowing in the heat-conducting component can be reliably controlled by controlling and adjusting the opening and closing of the first water inlet valve and the second water outlet valve and the opening and closing of the second water inlet valve and the first water outlet valve, thereby further improving the thermal insulation effect of the wall.

[0022] Optionally, the first water storage tank can be located on the roof of the building and used to store a heat-conducting medium for transferring heat to the surface of the wall, and the second water storage tank can be located below the ground and used to store a heat-conducting medium for absorbing heat from the surface of the wall.

[0023] By adopting the above technical solution, the first water storage tank is arranged on the roof of the building, so that the heat-conducting medium in the first water storage tank can be heated by solar energy. The second water storage tank is arranged below the ground, so that the heat-conducting medium in the second water storage tank can be naturally cooled. In this way, the temperature of the heat-conducting medium can be controlled without consuming energy, thereby reliably insulating the wall.

[0024] Optionally, the heat conduction assembly includes two transverse tubes and a plurality of vertical tubes, the ends of the two transverse tubes are sealed, the plurality of vertical tubes are spaced apart between the two transverse tubes, and the ends of the vertical tubes are respectively and one-to-one connected to the two transverse tubes;

[0025] The first branch pipe is connected to the top of the uppermost transverse pipe, and the second branch pipe is connected to the bottom of the lowermost transverse pipe;

[0026] The two horizontal tubes of two adjacent heat-conducting components are connected via a butt-joint tube;

[0027] A plurality of through holes are provided on the side wall of the vertical pipe, and sealing plugs are adaptively provided in the through holes. An elastic ring is sleeved on the outer wall of the sealing plug, and the elastic ring is interference fit with the through holes.

[0028] By adopting the above technical solution, under the docking action of the docking pipe, the two adjacent heat-conducting components in the vertical direction can be reliably connected. Under the connection action of the first branch pipe, the heat-conducting component located at the top will be connected to the first water collecting pipe, and under the connection action of the second branch pipe, the heat-conducting component located at the bottom will be connected to the second water collecting pipe. In this way, the several heat-conducting components in each heat-conducting component module are in a state of mutual connection, so that the heat-conducting medium can circulate in the first water collecting pipe, the heat-conducting component module and the second water collecting pipe, and the first water collecting pipe and the second water collecting pipe play a role in draining and guiding the heat-conducting medium, ensuring that there is sufficient heat-conducting medium flowing in each heat-conducting component module, thereby ensuring reliable insulation effect on the wall.

[0029] Optionally, one end of the butt joint is connected to the transverse pipe, the other end of the butt joint is provided with a sleeve, a butt joint is provided in the sleeve, one end of the butt joint is connected to the inner wall of the sleeve and there is a distance between the butt joint and the butt joint;

[0030] The other end of the butt joint is in an arc shape, and the other end of one butt joint and the other end of another adjacent butt joint are squeezed against each other;

[0031] A docking channel is provided in the docking joint, and the docking channel passes through the docking joint in the axial direction. A plurality of steel rings are provided on the inner side of the docking joint, and the steel rings are used to support the docking channel in an unobstructed state.

[0032] By adopting this technical solution, once the insulation cover is installed, the two butt joints within the two heat-conducting components will be in a butted state. Specifically, a gap exists between the two adjacent insulation cover plates, and the two butt joints are squeezed together, allowing the two butt joints to be securely connected, thereby ensuring that the two adjacent heat-conducting components are in a state of interconnection. Due to the limiting effect of the steel ring, the butt joints will not become blocked during the mutual squeezing process, ensuring that the heat transfer medium can flow between the heat-conducting components through the butt joints and butt joints.

[0033] The control method of the exterior wall thermal insulation system is applied to the exterior wall thermal insulation system and includes the following steps:

[0034] S1. When the outdoor temperature is lower than a preset value, the first water inlet valve and the second water outlet valve are opened, and the first water outlet valve and the second water inlet valve are closed, so that the heat transfer medium in the first water storage tank circulates between the heat transfer component and the first water storage tank, thereby transferring the heat in the heat transfer medium to the surface of the wall to achieve auxiliary temperature increase;

[0035] S2. When the outdoor temperature is higher than a preset value, the second water inlet valve and the first water outlet valve are opened, and the second water outlet valve and the first water inlet valve are closed, so that the heat transfer medium in the second water storage tank circulates between the heat transfer component and the second water storage tank, thereby transferring the heat on the surface of the wall to the heat transfer medium to achieve auxiliary cooling.

[0036] By adopting the above technical solution, the walls can be effectively insulated in environments with different temperatures, ensuring that the temperature inside the building is maintained at a relatively constant state.

[0037] Compared with the existing technology, this application has the following beneficial effects:

[0038] 1. While installing the insulation cover on the frame body, the heat conduction component is docked. Then, by transporting the heat conduction medium in the heat conduction component, the heat is transported to the wall or the heat in the wall is absorbed, thereby heating or cooling the wall at different temperatures, thereby achieving reliable active insulation of the wall.

[0039] 2. By controlling the opening and closing states of the first water inlet valve, the first water outlet valve, the second water inlet valve, and the second water outlet valve, the higher-temperature heat-conducting medium in the first water storage tank can be selectively input into the heat-conducting component, or the lower-temperature heat-conducting medium in the second water storage tank can be input into the heat-conducting component. Thus, heat-conducting media of different temperatures are selected to circulate in the heat-conducting component according to different ambient temperatures, thereby maximizing the thermal insulation effect on the wall.

[0052] Next, in combination with the appended Figures 1-5 and the detailed implementation manners, the present application will be further described. It should be noted that, on the premise of no conflict, the following-described embodiments or technical features can be arbitrarily combined to form new embodiments.

[0053] This embodiment discloses an exterior wall thermal insulation system.

[0054] Figure 1 It is a schematic perspective view of the present application. Refer to Figure 1 , the exterior wall thermal insulation system is arranged on the surface of the wall 1, playing a role in thermal insulation for the wall 1, keeping the temperature inside the building in a relatively constant state, and reducing the energy consumption brought by using equipment such as air conditioners to control the temperature inside the building.

[0055] Figure 2This is a reference diagram of the assembly status of the frame assembly and the heat conduction assembly. Figure 2 The exterior wall insulation system includes a frame assembly 2, an insulation cover 3, and a heat-conducting assembly 4. The frame assembly 2 includes a frame body 21 and a fixing base 22. The fixing base 22 is detachably mounted on the surface of the wall 1. The frame body 21 is fixed by at least four fixing bases 22 and is arranged in a grid pattern. The insulation cover 3 has lugs 31 on its side walls. The lugs 31 are fixed to the frame assembly 2 with bolts 32. This ensures that each insulation cover 3 is securely fixed to the frame body 21. At the same time, after the insulation cover 3 is fixed, there will be a gap between the two adjacent insulation cover plates 3, which can be filled with sealant to improve the aesthetics. Furthermore, the insulation cover plate 3 is in a square cover shape, ensuring that there is enough space between the insulation cover plate 3 and the surface of the wall 1 for placing the heat-conducting component 4. When the gap is filled with sealant, the space is in a relatively closed state, which can prevent external air from flowing in the space and causing excessive heat loss to a certain extent, thereby improving the insulation effect of the insulation cover plate 3 on the foundation of the wall 1.

[0056] Figure 3 is a schematic perspective view of a heat conducting component. Figure 3 and combined Figure 2, the heat conduction component 4 includes two horizontal pipes 45 and several vertical pipes 46. The ends of the two horizontal pipes 45 are both in a sealed state. The several vertical pipes 46 are arranged at intervals between the two horizontal pipes 45. The two ends of the vertical pipes 46 are respectively and correspondingly communicated with the two horizontal pipes 45. A heat conduction component 4 is correspondingly arranged on the inner side of each heat preservation cover plate 3. Moreover, the heat conduction component 4 is in a separated state from the heat preservation cover plate 3 and in a mutually attached state with the wall body 1. Further, both the horizontal pipe 45 and the vertical pipe 46 are square pipes. In this way, the horizontal pipe 45 and the vertical pipe 46 can contact the wall body 1 with a larger area. A first water collecting pipe 41 is arranged at the upper end of the frame body 21, and a second water collecting pipe 42 is arranged at the lower end. Both the first water collecting pipe 41 and the second water collecting pipe 42 extend along the width direction of the frame body 21. A number of first branch pipes 411 are arranged at the bottom of the first water collecting pipe 41, and a number of second branch pipes 421 are arranged at the top of the second water collecting pipe 42. The several heat conduction components 4 are arranged in a grid pattern. All the heat conduction components 4 in the same column can form a heat conduction component 4 module, and several heat conduction component 4 modules also extend along the width direction of the frame body 21. In a heat conduction component 4 module, the heat conduction component 4 at the uppermost part is communicated with the first branch pipe 411 (specifically, the upper horizontal pipe 45 in this heat conduction component 4 is communicated with the first branch pipe 411), the heat conduction component 4 at the lowermost part is communicated with the second branch pipe 421 (specifically, the lower horizontal pipe 45 in this heat conduction component 4 is communicated with the second branch pipe 421), and the other heat conduction components 4 in the middle are communicated with each other through a docking pipe 47 (specifically, a docking pipe 47 is arranged on the horizontal pipe 45 of these heat conduction components 4). In this way, under the communication action of the first branch pipe 411, the docking pipe 47 and the second branch pipe 421, the first water collecting pipe 41, each heat conduction component 4 in the heat conduction component 4 module and the second water collecting pipe 42 are in a mutually communicated state.

[0057] See Figure 1 and Figure 2, a first water inlet pipe 412 and a first water outlet pipe 413 are provided on the first water collecting pipe 41, a second water inlet pipe 422 and a second water outlet pipe 423 are provided on the second water collecting pipe 42, a first water inlet valve 4120 is provided on the first water inlet pipe 412, a second water inlet valve 4220 is provided on the second water inlet pipe 422, a first water outlet valve 4130 is provided on the first water outlet pipe 413, and a second water outlet valve 4230 is provided on the second water outlet pipe 423. A first water storage tank 43 is provided above the wall 1, and a second water storage tank 44 is provided below the wall 1. The first water inlet pipe 412 and the second water outlet pipe 423 are both communicated with the first water storage tank 43, and the second water inlet pipe 422 and the first water outlet pipe 413 are both communicated with the second water storage tank 44. Heat-conducting medium can be stored in both the first water storage tank 43 and the second water storage tank 44. Moreover, the first water storage tank 43 can be arranged on the top of the building, so that solar energy can be used to heat the heat-conducting medium in the first water storage tank 43, so that the heat-conducting medium in the first water storage tank 43 is in a state of higher temperature. The second water storage tank 44 can be arranged below the ground, so that the heat-conducting medium in the second water storage tank 44 is in a state of lower temperature by utilizing the characteristic of lower underground temperature.

[0058] The first water inlet valve 4120 and the second water outlet valve 4230 are in the same opening and closing state, the second water inlet valve 4220 and the first water outlet valve 4130 are in the same opening and closing state, and the first water inlet valve 4120 and the second water inlet valve 4220 are in opposite opening and closing states. Thus, when the first water inlet valve 4120 and the second water outlet valve 4230 are in the open state and the second water inlet valve 4220 and the first water outlet valve 4130 are in the closed state, the heat-conducting medium with a higher temperature in the first water storage tank 43 will sequentially pass through the first water inlet pipe 412, the first water collecting pipe 41, and the heat-conducting component 4 and enter the second water collecting pipe 42, and finally flow back to the first water storage tank 43 through the second water outlet pipe 423. The heat-conducting medium in the second water storage tank 44 will stay in the second water storage tank 44. Since the heat-conducting component 4 and the wall 1 are in a mutually attached state, when the heat-conducting medium with a higher temperature flows in the heat-conducting component 4, the heat in the heat-conducting component 4 will be transferred to the surface of the wall 1, playing a role in heating the wall 1. When the second water inlet valve 4220 and the first water outlet valve 4130 are in the open state and the first water inlet valve 4120 and the second water outlet valve 4230 are in the closed state, the heat-conducting medium with a lower temperature in the second water storage tank 44 will sequentially pass through the second water inlet pipe 422, the second water collecting pipe 42, and the heat-conducting component 4 and enter the first water collecting pipe 41, and finally flow back to the second water storage tank 44 through the first water outlet pipe 413. The heat-conducting medium in the first water storage tank 43 will stay in the first water storage tank 43. Thus, when the heat-conducting medium with a lower temperature flows in the heat-conducting component 4, the heat-conducting component 4 will absorb the heat on the surface of the wall 1, playing a role in cooling the wall 1. That is to say, when in an environment with a lower temperature such as winter, a heat-conducting medium with a higher temperature is selected to flow in the heat-conducting component 4, and when in an environment with a higher temperature such as summer, a heat-conducting medium with a lower temperature is selected to flow in the heat-conducting component 4. In this way, without consuming too much additional energy, the temperature difference between the wall 1 and the temperature inside the building can be kept in a relatively constant state, thus playing a reliable heat preservation role for the wall 1, and the control accuracy of the heat preservation effect can be improved by adjusting the temperature and flow rate of the heat-conducting medium, significantly enhancing the heat preservation effect.

[0059] Figure 4 is the internal structure sectional view of the butt joint pipe. See Figure 4 and combine with Figure 2, one end of the docking pipe 47 communicates with the horizontal pipe 45, the other end of the docking pipe 47 is provided with a sleeve 471, a docking head 472 is arranged inside the sleeve 471, one end of the docking head 472 is connected to the inner wall of the sleeve 471 and there is a distance between it and the docking pipe 47, the other end of the docking head 472 is arc-shaped, the other end of one docking head 472 is squeezed against the other end of an adjacent docking head 472, a docking channel 4721 is arranged inside the docking head 472, the docking channel 4721 axially penetrates the docking head 472, and a number of steel rings 4722 are arranged on the inner side of the docking head 472, and the steel rings 4722 are used to support the docking channel 4721 to be in an unobstructed state. The horizontal pipe 45 of the heat conduction component 4 can be clamped inside the heat preservation cover plate 3, so as to realize the fixation of the heat conduction component 4, or the heat conduction component 4 can be directly fixed on the surface of the wall body 1 through structures such as clamps. In this way, during the installation of the heat preservation cover plate 3 or the heat conduction component 4, the two docking pipes 47 of two adjacent heat conduction components 4 in the same heat conduction component 4 module will approach each other, and a certain extrusion will occur between the corresponding two docking heads 472, so as to ensure that the corresponding two docking channels 4721 can be in a reliable sealing state, and it is ensured that two adjacent heat conduction components 4 can be reliably docked and communicated through the docking pipe 47. During the extrusion of the two docking heads 472, the docking channel 4721 will produce a certain deformation, and under the action of the steel ring 4722, the docking channel 4721 can maintain an unobstructed state, ensuring that after docking, the heat conduction medium can flow through the docking channel 4721 reliably.

[0060] Figure 5 is an exploded state reference diagram of the vertical pipe. Refer to Figure 5 and in combination with Figure 2 , further, a number of through holes 461 are arranged on the side wall of the vertical pipe 46, sealing plugs 462 are adaptively arranged in the through holes 461, an elastic ring 4620 is sleeved on the outer wall of the sealing plug 462, and the elastic ring 4620 is in interference fit with the through hole 461. During the normal flow of the heat conduction medium, the sealing plug 462 can reliably seal the through hole 461 to ensure the reliable heat preservation effect on the wall body 1. When a fire occurs inside the building, the first water inlet valve 4120 and the second water inlet valve 4220 can be opened simultaneously and the first water outlet valve 4130 and the second water outlet valve 4230 can be closed. In this way, the heat conduction media in the first water storage tank 43 and the second water storage tank 44 will both flow towards the heat conduction component 4. When the pressure of the heat conduction medium in the heat conduction component 4 reaches the threshold value, the sealing plug 462 will be pushed out of the through hole 461. At this time, the heat conduction medium will flow out of the heat conduction component 4 and fall onto the surface of the wall body 1, which can play a certain role in cooling and extinguishing the fire. At the same time, through holes 33 can be opened below the front of the heat preservation cover plate 3. When the heat conduction medium flows out, it can pass through the through holes 33 and flow on the surface of the heat preservation cover plate 3, which can play a warning role and expand the functionality of the heat preservation system.

[0061] This embodiment also discloses a control method for an external wall thermal insulation system.

[0062] The control method for the external wall thermal insulation system, which is applied to the external wall thermal insulation system, includes the following steps:

[0063] S1. When the outdoor temperature is lower than the preset value, open the first water inlet valve 4120 and the second water outlet valve 4230, and close the first water outlet valve 4130 and the second water inlet valve 4220, so that the heat-conducting medium in the first water storage tank 43 circulates between the heat-conducting component 4 and the first water storage tank 43, thereby delivering the heat in the heat-conducting medium to the surface of the wall 1 to achieve auxiliary heating;

[0064] S2. When the outdoor temperature is higher than the preset value, open the second water inlet valve 4220 and the first water outlet valve 4130, and close the second water outlet valve 4230 and the first water inlet valve 4120, so that the heat-conducting medium in the second water storage tank 44 circulates between the heat-conducting component 4 and the second water storage tank 44, thereby delivering the heat on the surface of the wall 1 to the heat-conducting medium to achieve auxiliary cooling.

[0065] By controlling the opening and closing states of the first water inlet valve 4120, the first water outlet valve 4130, the second water inlet valve 4220, and the second water outlet valve 4230, it is possible to select heat-conducting media at different temperatures to flow in the heat-conducting component 4, thereby improving the thermal insulation effect of the thermal insulation system on the surface of the wall 1.

[0066] The above-mentioned implementation manners are only the preferred implementation manners of the present application, and cannot be used to limit the protection scope of the present application. Any non-substantial changes and substitutions made by those skilled in the art based on the present application belong to the protection scope required by the present application.
