Description

Technical Field

[0001] The utility model relates to a block connection of large-size panels of a combined air-conditioning unit box in the field of air-conditioning equipment, in particular to an anti-cold bridge intermediate aluminum. Background Art

[0002] When modular air conditioning unit panels are oversized and processing is limited, they are often designed and assembled in sections. The sections are often connected using sheet metal U-slot screws or an all-aluminum intermediate connection. This type of connection is prone to deformation, resulting in severe air leakage, significant limitations, time-consuming and labor-intensive maintenance, and poor overall cabinet strength. The addition of an all-aluminum intermediate connection creates direct contact between the intermediate and aluminum frame, without any sealing measures. This can lead to air leakage and cold bridges, resulting in internal cooling and heat loss within the unit. Summary of the Invention

[0003] In order to solve the drawbacks of the existing large-size panel block connection form of combined air-conditioning units, the utility model provides an anti-cold bridge intermediate aluminum. The T-shaped structure with high-strength nylon insulation strips effectively ensures the sealing and flatness of the connection between adjacent panels, and is effectively combined with special nylon straight-through to eliminate air leakage and cold bridges between the panel, intermediate aluminum and the unit aluminum profile frame, making the unit panel installation and maintenance convenient and the overall unit beautiful.

[0004] The technical solution adopted by the present invention to solve its technical problems is as follows: providing an anti-cold bridge intermediate aluminum, which is composed of an outer cavity, an inner cavity and a thermal insulation strip. Both the outer cavity and the inner cavity are high-strength aluminum alloy special-shaped components. The outer cavity is a single cavity, and the inner cavity is a three-cavity cavity. The inner and outer cavities are connected to each other to install the thermal insulation strip, leaving a trapezoidal mounting hole on the side. The end of the inner cavity is provided with a through-type convex knife groove and a self-drilling and self-tapping screw fixing limit line at the joint between the panel and the panel. The knife groove and the sealing strip on the panel are tightly squeezed and sealed to prevent air leakage. The self-drilling and self-tapping screw fixing limit line facilitates the positioning and installation of the self-drilling and self-tapping screws that fasten the present invention to the panel. The thermal insulation strip is made of "J"-shaped high-strength nylon. The inner and outer cavities are connected into one by the thermal insulation strip, and the overall structure is a T-shaped five-cavity structure.

[0005] In actual application, the utility model is added at the joint of the divided panels, a sealing strip is pasted on the panel, and then the self-drilling and self-tapping screws on the hexagonal flange are used to fix the panel and the anti-cold bridge middle aluminum firmly along the self-drilling and self-tapping screw fixing limit line on the utility model to complete the connection of the divided panels.

[0006] The utility model is a custom-made piece of fixed length, which can be cut and used according to the size of the unit.

[0007] The beneficial effects of this utility model include providing an anti-cold-bridge intermediate aluminum panel. Its T-shaped structure with built-in high-strength nylon insulation strips effectively ensures the tightness and flatness of adjacent panel connections. Furthermore, its effective combination with specialized nylon through-holes eliminates air leakage and cold bridges between the panels, intermediate aluminum panel, and the unit's aluminum profile frame. This facilitates panel installation and maintenance, and enhances the overall aesthetics of the unit. BRIEF DESCRIPTION OF THE DRAWINGS

[0013] like Figure 1 As shown, the utility model is composed of an outer cavity, an inner cavity, and a thermal insulation strip. Both the outer cavity and the inner cavity are high-strength aluminum alloy special-shaped components. The outer cavity is a single cavity, while the inner cavity is a triple cavity. Trapezoidal mounting holes are left on the side where the inner and outer cavities are butted against the thermal insulation strip. The inner cavity end is provided with a through-type convex knife groove and self-drilling and self-tapping screw fixing limit lines where it meets the panel. The thermal insulation strip is made of "J"-shaped high-strength nylon. The inner and outer cavities are connected by the thermal insulation strip, forming a T-shaped five-cavity structure.

[0014] In actual application, the utility model is added at the joint of the divided panels, a sealing strip is pasted on the panel, and then the self-drilling and self-tapping screws on the hexagonal flange are used to fix the panel and the anti-cold bridge middle aluminum firmly along the self-drilling and self-tapping screw fixing limit line on the utility model to complete the connection of the divided panels.

[0015] The utility model is a customized piece with a fixed length, which can be cut and used according to the size of the unit.
