Description

Technical Field

[0001] This utility model relates to the field of heating, ventilation and air conditioning equipment technology, and in particular to a central air conditioning pipe insulation structure. Background Technology

[0002] The main purpose of HVAC duct insulation structures is to reduce energy loss and prevent condensation on pipes, thereby reducing energy consumption and improving the thermal efficiency of the piping system. Insulation structures can effectively reduce the impact of ambient temperature on the medium being transported, maintaining a stable medium transmission temperature, thus saving energy and reducing greenhouse gas emissions. Furthermore, insulation structures can prevent condensation on pipes, avoiding the impact of condensate on the surrounding environment and equipment, and extending the service life of the pipes. However, existing insulated ductwork is inconvenient to install on HVAC ducts of different shapes, such as bent pipes. Moreover, if the installed HVAC ducts are long or have varying diameters, additional filling or cutting to the corresponding specifications is required, further hindering installation and use. Utility Model Content

[0003] The purpose of this utility model is to provide a central air conditioning duct insulation structure to solve the problems existing in the prior art.

[0004] The above-mentioned technical objective of this utility model is achieved through the following technical solution:

[0005] A central air conditioning duct insulation structure includes an insulated duct composed of an inner hydrophobic layer, a middle insulation filling layer, and an outer structural reinforcement layer. Both ends of the insulated duct have outwardly folded flanges, and each flange has multiple through holes evenly distributed circumferentially. The inner hydrophobic layer inside both ends of the insulated duct has a receiving groove, and a magnetic seal is installed within the receiving groove. The receiving groove is circumferentially annular and extends through to the middle insulation filling layer. The hydrophobic layer is bonded and fixed to the insulation filling layer, and the structural reinforcement layer is bolted and fixed to the insulation filling layer. The outer wall of the insulation filling layer has multiple threaded blind holes evenly spaced, and the structural reinforcement layer has clearance holes corresponding to the threaded blind holes. Multiple reinforcing ribs are provided on the outer side of the structural reinforcement layer.

[0006] By adopting the above technical solution, the insulation filling layer is placed between the hydrophobic layer and the structural reinforcement layer. This achieves the insulation function without affecting the aesthetics of the pipeline. Since the structures are consistent, there are no difficulties in the installation. Furthermore, the direct contact between the hydrophobic layer and the structural reinforcement layer is cut off at both ends of the insulated pipeline through receiving grooves, and magnetic sealing strips are used to prevent direct contact between the inner and outer layers of the insulated pipeline, thus achieving airtightness at the connection and avoiding heat transfer caused by direct contact between the inner and outer layers of the insulated pipeline, further increasing the insulation performance of the pipeline.

[0007] In a further embodiment, the outer bottom of the insulated pipe is provided with a plurality of rectangular protrusions at equal intervals along the length of the pipe, and the rectangular protrusions are integrally formed with the outer structural reinforcement layer of the insulated pipe.

[0008] By adopting the above technical solution, the rectangular protrusions are used to support the cable tray, which facilitates the installation of pipes and makes the pipes more evenly stressed on the cable tray.

[0009] In a further embodiment, the surface of the inner hydrophobic layer is coated with an antibacterial layer.

[0010] In a further embodiment, the insulation filling layer of the insulated pipe is a porous foam filler.

[0011] In a further embodiment, the structural reinforcement layer is a galvanized sheet.

[0012] In summary, this utility model has the following beneficial effects:

[0013] 1. By placing the insulation filling layer between the hydrophobic layer and the structural reinforcement layer, the insulation function can be achieved without affecting the aesthetics of the pipeline. Since the structures are consistent, there are no difficulties in the connection and installation. Furthermore, the direct contact between the hydrophobic layer and the structural reinforcement layer is cut off at both ends of the insulated pipeline through receiving grooves, and magnetic sealing strips are used to prevent direct contact between the inner and outer layers of the insulated pipeline, thus achieving airtightness at the connection and avoiding heat transfer caused by direct contact between the inner and outer layers of the insulated pipeline, further increasing the insulation performance of the pipeline.

[0019] Example 1:

[0020] like Figures 1-2 As shown, a central air conditioning duct insulation structure includes an insulated duct 1 composed of an inner hydrophobic layer 11, a middle insulation filling layer 12, and an outer structural reinforcement layer 13. Both ends of the insulated duct 1 are provided with outwardly folded flanges, and multiple through holes are evenly arranged circumferentially on the flanges. The inner hydrophobic layer 11 inside both ends of the insulated duct 1 is provided with receiving grooves, and magnetic seals 2 are provided in the receiving grooves. The receiving grooves are circumferentially arranged and penetrate to the middle insulation filling layer 12. Therefore, after the foam of the middle insulation filling layer has cured, it is necessary to cut the ends of the insulation filling layer with a tool to avoid damaging the sealing performance. The hydrophobic layer 11 is bonded and fixed to the insulation filling layer 12, and the structural reinforcement layer 13 is bonded and fixed to the insulation filling layer 12. The filling layer 12 is bolted and fixed. The outer wall of the insulation filling layer 12 is provided with multiple threaded blind holes at equal intervals. The structural reinforcement layer 13 is provided with avoidance holes corresponding to the threaded blind holes. Multiple reinforcing ribs are provided on the outer side of the structural reinforcement layer 13. Because the insulation pipe 1 is a slender structure after splicing, reinforcing ribs need to be provided on the outer side of the insulation pipe to avoid excessive deformation of the insulation pipe 1. Multiple rectangular protrusions are provided at equal intervals along the length of the pipe on the bottom outer side of the insulation pipe 1. The rectangular protrusions are integrally formed with the outer structural reinforcement layer 13 of the insulation pipe 1. The surface of the inner hydrophobic layer 11 is sprayed with an antibacterial layer. The insulation filling layer 12 of the insulation pipe 1 is a porous foam filler, and the structural reinforcement layer 13 is a galvanized sheet.

[0021] Specific implementation process: During use, the hydrophobic layer 11 needs to be fixed inside the structural reinforcement layer 13 using a jig. Then, bolts are passed through the clearance holes of the structural reinforcement layer 13, followed by the filling of expanding foam. The expanding foam expands and cures to form the insulation filling layer 12. Because it is filled with expanding foam, its porous structure provides excellent insulation. Furthermore, the expanding foam itself has a certain adhesive strength and structural strength, making it more suitable as the filling material for the middle layer of the insulation pipe 1 compared to porous materials like sponge. The hydrophobic layer and the structural reinforcement layer are then fixed together, forming a threaded blind hole. The outer wall of the hydrophobic layer needs to be roughened to increase the adhesive strength of the expanding foam. During the pipe connection process, a magnetic sealing strip is inserted into the receiving groove, and then the pipe is locked in place using bolts, nuts, and through holes on the flange. By placing the insulation filling layer between the hydrophobic layer and the structural reinforcement layer, the aesthetics of the pipe are not affected. While maintaining aesthetic appeal, the insulation also serves a thermal insulation function. Since all layers have a consistent structure, there are no installation difficulties. Furthermore, at both ends of the insulated pipe, a receiving groove cuts off direct contact between the hydrophobic layer and the structural reinforcement layer, and a magnetic sealing strip is used to prevent airtightness at the connection point. This also avoids heat transfer caused by direct contact between the inner and outer layers of the insulated pipe, further increasing its insulation performance. During installation, bolts are also fixed within the clearance holes to ensure their verticality and prevent them from tilting during the curing of the foam. After a certain number of years (5-6 years) of use, the bolts are removed, the middle insulation layer is cleaned, and new foam is sprayed to form a new insulation layer 12. This restores the insulation effect of the entire insulated pipe, avoids material waste, and greatly reduces the maintenance cost of the insulated pipe 1.

[0022] In the embodiments disclosed in this utility model, the terms "installation," "connection," "linking," and "fixing" should be interpreted broadly. For example, "connection" can be a fixed connection, a detachable connection, or an integral connection; "linking" can be a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in the embodiments disclosed in this utility model according to the specific circumstances.

[0023] This specific embodiment is merely an explanation of the present utility model and is not intended to limit the present utility model. After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive step, but as long as they are within the scope of the claims of the present utility model, they are protected by patent law.
