Abstract
Description
Technical Field
[0001] This utility model relates to the field of anti-cold bridge technology, and in particular to an anti-cold bridge aluminum profile structure. Background Technology
[0002] In the refrigeration industry, the concept of a cold bridge is defined as follows: due to differences in the local structure of the insulation of a cold storage facility, the insulation performance of that part is reduced, becoming a channel for the large-scale transfer of cold energy, which is called a "cold bridge".
[0003] Aluminum alloy is a good conductor of heat, and the chassis frame easily conducts heat exchange, which can have an adverse effect on the refrigeration industry where it is used.
[0004] For example, patent CN206769684U discloses a filled thermal insulation profile. The main technical feature of this patent is the setting of thermal insulation units to provide thermal insulation between aluminum profiles. However, when installing anti-cold panels on aluminum profiles, the outer surface of the aluminum profile has a large air contact area, which causes condensation on the metal. Moreover, the surfaces in contact with the anti-cold panels are all aluminum profiles. On the other hand, the protruding part of the aluminum profile has only one long strip structure, which is weak in strength. In addition, when installing anti-cold panels, they are usually fixed to the side of the aluminum profile with screws. However, since the aluminum profile itself is not thick, the fixing strength is also insufficient.
[0005] To address this issue, a cold-bridge-resistant aluminum profile structure is proposed. Utility Model Content
[0006] To solve the above-mentioned technical problems, the purpose of this utility model is to provide an anti-cold bridge aluminum profile structure that can reduce the thermal conductivity of the frame and increase the strength of the frame.
[0007] The technical solution adopted by this utility model to solve the problem is: a cold bridge-resistant aluminum profile structure, including an outer frame and an inner frame, with a connecting strip connecting the outer frame and the inner frame. The inner frame includes an inclined portion, with a first vertical portion and a first horizontal portion connected to both ends of the inclined portion. A second horizontal portion is connected to the end of the first vertical portion, and a second vertical portion is connected to the end of the first horizontal portion. An arc-shaped connecting portion is connected between the second horizontal portion and the second vertical portion, and a reinforcing rib is connected between the center point of the connecting portion and the center point of the inclined portion.
[0008] As a further improvement to the above technical solution, the inner ends of the first vertical part and the first horizontal part are provided with slots, which are used to engage steel bars.
[0009] As a further improvement to the above technical solution, the outer frame is L-shaped.
[0010] As a further improvement to the above technical solution, a first groove is provided at both ends of the outer frame, and a second groove is provided at the outer ends of the first vertical part and the first horizontal part. The first groove and the second groove are arranged facing each other, and a protrusion is provided at both ends of the connecting strip. The protrusion is engaged with the first groove and the second groove.
[0011] As a further improvement to the above technical solution, the connecting strip is made of bakelite.
[0012] The beneficial effects of this utility model are: a connecting strip connects the outer frame and the inner frame, which acts as an anti-cold bridge and has good impact resistance, heat resistance and low temperature resistance. It can increase the distance between the outer frame and the inner frame while reducing the heat conduction of the frame. In addition, the inner frame is provided with reinforcing ribs, which increases the strength of the inner frame. Attached Figure Description
