DETAILED DESCRIPTION OF THE EMBODIMENTS

[0015] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0016] As Figure 1 and Figure 2 shown, an improved aluminum alloy profile includes a profile body 1. Cavities 2 are constructed on both the left and right sides of the profile body 1. A sound insulation cavity 3 is constructed on the upper side of the middle part of the profile body 1. Sound insulation cotton 4 is filled in the sound insulation cavity 3. A card slot 5 is opened on the lower side of the middle part of the profile body 1. Support plates 6 are connected to both the left and right sides of the top end of the profile body 1. A plurality of sound absorption boards 7 are connected from top to bottom in the cavity 2. Reinforcement plates 8 are connected to the upper and lower ends of the outer side of the cavity 2 at the corners. A plurality of heat dissipation boards 9 are arranged at equal intervals on the other end surface of the reinforcement plate 8 away from the corner.

[0017] Please refer to Figure 2As shown in the figure, a support bar 10 is connected to the upper part of the inner end face of the support plate 6. A plurality of water inlet holes 11 are formed on both the left and right sides of the top surface of the profile body 1. The water inlet holes 11 are located below the corresponding support bar 10 on one side. The bottom of the water inlet holes 11 is communicated with the reinforcing plate 8 at the upper end on the same side. A plurality of water outlet holes 12 are formed on the upper sides of the left and right end faces of the profile body 1. The water outlet holes 12 are communicated with the reinforcing plate 8 at the upper end on the same side. Heat insulation cotton 13 is filled between the sound absorption plate 7 closest to the sound insulation cavity 3 and the outer wall of the sound insulation cavity 3. The sound absorption plate 7 has a structure with the middle bent inward.

[0018] The working principle of this embodiment is as follows:

[0019] The sound emitted from the outside will be effectively rebounded and blocked by the sound absorption plate 7 with an inclined angle, and the noise will be silenced. The sound insulation cotton 4 in the middle sound insulation cavity 3 can prevent air transmission and isolate the outside noise, which can further improve the sound insulation effect; when the profile is irradiated by the sun for a long time, the metal has good thermal conductivity. Through the design of the heat dissipation plate 9, the heat on the surface of the profile is dissipated into the cavity 2. The air in the cavity 2 is used to absorb the heat, and the hot air will stay in the cavity 2. Then, through the design of the heat insulation cotton 13, the heat is blocked for heat preservation, and the heat insulation is further realized. By conducting the heat into the cavity 2, the residence time of the heat on the metal is reduced, and the heat transfer can be slowed down as much as possible, and the influence on the indoor temperature can be minimized as much as possible; when it rains, the rainwater on the glass plate will converge downward, flow to the gap, and penetrate into the glass groove. The design of the water inlet holes 11 and the water outlet holes 12 can discharge the rainwater infiltrated from the top surface of the profile body 1. The reinforcing plate 8 can play a guiding role and ensure that the water does not flow into the cavity 2.

[0020] Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
