[0022] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0023] An outdoor water supply composite pipe with good thermal insulation effect, such as Figures 1 to 3 As shown, it includes: a heat-absorbing rubber-plastic insulation sleeve 1 and a water-permeable butylene tube 6. The heat-absorbing rubber-plastic insulation sleeve 1 can absorb sunlight heat, increase its own temperature, and reduce the speed of internal heat dissipation; the water-permeable butylene tube 6 is used to guide hot water, and its own thermal conductivity is low, which is convenient for outdoor use.

[0024] A plurality of flow-guiding and heat-collecting spiral grooves 7 are equidistantly provided inside the water-passing butene tube 6. The flow-guiding and heat-collecting spiral grooves 7 cause the hot water inside the water-passing butene tube 6 to rotate during the flow, forming a vortex state. Part of the heat of the hot water will be collected inside the flow-guiding and heat-collecting spiral grooves 7. Combined with the low thermal conductivity of the water-passing butene tube 6 itself, the speed at which the heat of the hot water dissipates is further reduced.

[0025] The outer wall of the water-permeable butylene tube 6 is uniformly and integrally formed with a plurality of connecting protrusions 8. The connecting protrusions 8 make the thickness of the water-permeable butylene tube 6 different, and cooperate with the heat-conducting spiral groove 7 to make the heat dissipation position of the hot water mainly concentrated in the thinner part of the wall of the water-permeable butylene tube 6; Figure 3 As shown, the spatial angle formed by the diverting and heat-gathering spiral groove 7 and the axis of the composite pipe is the spiral groove spiral angle a, a is thirty degrees, ensuring the flow rate of hot water; the distance between two adjacent diverting and heat-gathering spiral grooves 7 is set to the spiral groove spacing b, b is set to five to ten millimeters, so the larger the inner diameter of the water-passing butylene tube 6, the more the diverting and heat-gathering spiral grooves 7 are.

[0026] An installation groove is provided inside the connecting protrusion 8, and the installation groove passes through the connecting protrusion 8. Its axis is parallel to the axis of the water-passing butylene tube 6, and a heat-collecting aluminum alloy tube 9 is fixedly installed inside the installation groove. The inner wall of the heat-collecting aluminum alloy tube 9 is evenly and integrally formed with multiple heat-collecting fins 10; when the hot water inside the water-passing butylene tube 6 transfers heat to the tube body, the heat is transferred evenly. The heat-collecting aluminum alloy tube 9 itself has good thermal conductivity and can quickly absorb heat and increase its own temperature. In conjunction with the heat-collecting fins 10, the heat is concentrated inside the heat-collecting aluminum alloy tube 9, reducing the temperature difference between the heat-collecting aluminum alloy tube 9 and the hot water, thereby reducing the dissipation rate of the hot water heat and improving the thermal insulation effect of the water-passing butylene tube 6.

[0027] The outer wall of the water-permeable butylene tube 6 is sleeved with a hybrid heat-insulating reinforcement skeleton 5, and the inner wall of the hybrid heat-insulating reinforcement skeleton 5 is equidistantly and integrally formed with multiple matching heat-collecting protrusions 11. The multiple matching heat-collecting protrusions 11 and the multiple connecting protrusions 8 are arranged at intervals, and the matching heat-collecting protrusions 11 completely fill the space between two adjacent connecting protrusions 8.

[0028] The main body of the mixed thermal insulation reinforcement frame 5 is set as a gypsum tube, and glass fiber cloth is set inside the gypsum tube. The glass fiber cloth serves as the skeleton of the gypsum tube to further improve the thermal insulation effect of the gypsum tube. Both of them are lightweight materials and have little impact on the weight of the overall composite pipe. The heat-collecting protrusion 11 corresponds to the thin-wall position of the water-permeable butylene tube 6 to improve the thermal insulation effect of the water-permeable butylene tube 6.

[0029] The thermal conductivity of gypsum is greater than that of glass fiber, and the thermal conductivity of glass fiber is greater than that of butene. After the hot water passes through the water-passing butene tube 6 and the heat-collecting aluminum alloy tube 9 for insulation treatment, the heat dissipated is relatively small. Under the action of gypsum and glass fiber, the heat is even less through the mixed insulation reinforcement skeleton 5, further improving the insulation effect of the overall composite pipe.

[0030] A mounting slot is provided on one side of the heat-collecting protrusion 11 close to the water-permeable butylene tube 6, and a hollow glass microbead strip 12 is fixedly installed inside the mounting slot; the main body of the hollow glass microbead strip 12 is set as a gypsum strip, and a plurality of hollow glass microbeads are set inside the gypsum strip.

[0031] Hollow glass microspheres are a tiny, hollow spherical powder with the advantages of light weight, large volume, low thermal conductivity, high compressive strength, good dispersibility, fluidity and stability. They also have excellent properties such as insulation, self-lubrication, sound insulation, non-water absorption, fire resistance, corrosion resistance, radiation protection and non-toxicity.

[0032] The hollow glass beads and gypsum can be fully mixed to form a hollow glass bead strip 12 that fits with the thin wall of the water-permeable butylene tube 6, further improving the thermal insulation effect of the water-permeable butylene tube 6 and reducing the sound of hot water flowing inside the water-permeable butylene tube 6.

[0033] The outer wall of the hybrid heat-insulating reinforcement skeleton 5 is sleeved with an insulating polyethylene tube 4. The raw material of the insulating polyethylene tube 4 is PE80 or PE100. The thermal conductivity of polyethylene is lower than that of gypsum and glass fiber, which further improves the thermal insulation performance of the overall composite pipe.

[0034] The outer wall of the thermal insulation polyethylene tube 4 is equidistantly sleeved with multiple sponge spiral protective tubes 3, and the interior of the sponge spiral protective tube 3 is filled with polyurethane foam. The material of the sponge spiral protective tube 3 is polyurethane foam sponge, which is combined with polyurethane foam to further improve the thermal insulation performance of the composite pipe. The spiral-shaped sponge spiral protective tube 3 can provide certain protection capabilities for other internal pipes, thereby improving the safety of the composite pipe.

[0035] The outer walls of multiple sponge spiral protective tubes 3 are sleeved with protective butylene tubes 2, which provide rigid protection for the overall composite tube and further improve the thermal insulation performance of the overall composite tube; the heat-absorbing rubber-plastic insulation sleeve 1 is sleeved on the outside of the protective butylene tube 2, and the heat-absorbing rubber-plastic insulation sleeve 1 absorbs sunlight heat to increase its own heat, forming a temperature difference with the protective butylene tube 2, and reducing the speed at which the protective butylene tube 2 dissipates heat to the outside.

[0036] Working principle:

[0037] Please refer to Figures 1 to 3 , the device is manufactured as shown in the figure;

[0038] When the composite pipe conducts hot water, the heat of the hot water is initially insulated by the heat-conducting and heat-collecting spiral grooves 7 and the heat-collecting aluminum alloy pipe 9 provided in the water-passing butene pipe 6 itself, thereby reducing the heat dissipation rate of the hot water; then the heat dissipation rate is further reduced by the mixed insulation reinforcement skeleton 5 and the hollow glass microbead strips 12, and the heat insulation effect of the composite pipe is maximized by the multi-layer combination of the heat-insulating polyethylene pipe 4, the sponge spiral protective pipe 3, the polyurethane foam and the protective butene pipe 2.

[0039] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
