Abstract
Description
Technical Field
[0001] This utility model relates to the field of aluminum profile technology, specifically to a strip-insulated aluminum profile structure. Background Technology
[0002] Thermally insulated aluminum profiles are a high-performance building material. By inserting thermally insulated connecting strips into the aluminum alloy profile, they not only maintain the overall integrity of the structure but also effectively improve the thermal insulation performance of doors and windows made from aluminum profiles. The principle is that the thermally insulated connecting strips, which are poor conductors of heat, interrupt the heat conduction path of the aluminum alloy, which is a good conductor of heat, significantly reducing heat transfer. Doors and windows made from aluminum profiles can reduce indoor heat loss in cold regions, block outdoor heat from entering in hot regions, and prevent rainwater infiltration and air leakage in high-humidity areas, thus reducing heating and cooling costs.
[0003] Existing heat-insulating aluminum profiles with through-bars have similar structures, mostly consisting of connecting strips that link the outer and inner profiles. They achieve heat insulation by interrupting the heat conduction path of the aluminum alloy. To further improve the heat insulation effect, heat-insulating strips are inserted inside the connecting strips to slow down or block heat transfer. Although they have a significant heat insulation effect, with the increasing demands for quality of life, there is still a high demand for heat-insulating aluminum profiles with through-bars, and the market still needs products with higher levels of heat insulation. Utility Model Content
[0004] To address the shortcomings of existing technologies, this utility model provides a strip-insulated aluminum profile structure to further improve the thermal insulation level of strip-insulated aluminum profiles.
[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution:
[0006] A heat-insulating aluminum profile structure includes an outer profile, an inner profile, and a connecting strip. The opposite surfaces of the outer profile and the inner profile are provided with slots, and the connecting strip is engaged with the outer profile and the inner profile through the slots provided on both sides.
[0007] The cavity of the outer profile is provided with multiple partitions, and a sheet-type heat insulation strip is provided in the cavity of the outer profile near the connecting strip.
[0008] The connecting strip has a hollow cuboid structure, and a rod-shaped heat insulation strip is provided inside the connecting strip. The top and bottom of the rod-shaped heat insulation strip are provided with slits, and the slits at the top and bottom of the rod-shaped heat insulation strip are arranged sequentially along the horizontal direction.
[0009] The inner wall of the card slot, the surface of the card strip, and the inner wall of the cavity of the connecting strip are all provided with heat insulation grooves. The heat insulation grooves are arranged longitudinally and are continuously arranged along the inner wall of the card slot, the surface of the card strip, and the inner wall of the cavity of the connecting strip.
[0010] Preferably, a groove is provided at the center of the opposite surface of both the outer profile and the inner profile.
[0011] Preferably, both the sheet-type and rod-type heat insulation strips are porous polyurethane pads.
[0012] Preferably, the heat insulation groove is a V-shaped groove, and the heat insulation groove on the inner wall of the card slot is arranged opposite to the heat insulation groove on the surface of the card strip.
[0013] Preferably, EPDM adhesive is provided between the top and bottom of the connecting strip and the outer and inner profiles on both sides.
[0014] Compared with the prior art, the present invention has the following beneficial effects:
[0015] This invention features an internal partition in the outer profile closest to the outside to prevent internal air convection heat transfer. A sheet-like thermal break slows the transfer of heat from the outside to the inside. The slits on the rod-shaped thermal break help create heat transfer breaks, increasing the heat transfer path length. Thermal grooves and recesses reduce the contact area between the outer profile, connecting strip, and inner profile, as well as the contact area between the connecting strip and the rod-shaped thermal break, thus reducing heat transfer. EPDM adhesive enhances the sealing effect after glass installation, preventing air convection at the joints. Through multi-faceted structural optimization, this invention improves the sealing effect, slows down and reduces heat transfer, achieving a further improvement in the thermal insulation level of the through-bar thermally insulated aluminum profile compared to existing technologies.
