Description

Technical Field

[0001] This utility model relates to the field of air conditioning unit technology, and in particular to an anti-cold bridge air conditioning unit. 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 prevention air conditioning unit is proposed to solve the aforementioned technical problems. Utility Model Content

[0006] To solve the above-mentioned technical problems, the purpose of this utility model is to provide an anti-cold bridge air conditioning unit that can reduce the heat conduction of the frame and increase the strength of the frame.

[0007] The technical solution adopted by this utility model to solve the problem is: an anti-cold bridge air conditioning unit, including a rectangular frame, an air conditioning component is arranged inside the frame, a load-bearing base is arranged at the bottom of the frame, the frame is assembled from a number of aluminum profile strips, a plate is arranged between adjacent aluminum profile strips, the aluminum profile strip includes an outer frame and an inner frame, a connecting strip is connected between the outer frame and the inner frame, and a reinforcing rib is connected to the inner frame.

[0008] As a further improvement to the above technical solution, the air conditioning component includes a filter, a cooling or heating coil and a fan arranged sequentially from left to right within the frame. The frame is provided with an air inlet and an air outlet, with the air inlet located to the left of the filter and the air outlet located to the right of the fan.

[0009] As a further improvement to the above technical solution, the plate is provided with a first inspection port and a second inspection port. The first inspection port is located between the air inlet and the filter, and the second inspection port is located beside the fan.

[0010] As a further improvement to the above technical solution, 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 connected to the end of the first vertical portion, a second vertical portion connected to the end of the first horizontal portion, and an arc-shaped connecting portion connecting the second horizontal portion and the second vertical portion. The reinforcing rib is connected to the center point of the connecting portion and the center point of the inclined portion.

[0011] 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.

[0012] As a further improvement to the above technical solution, the outer frame is L-shaped.

[0013] As a further improvement to the above technical solution, the connecting strip is made of bakelite.

[0014] The beneficial effects of this utility model are: a connecting strip is provided between the outer frame and the inner frame. The connecting strip 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 effectively preventing heat transfer between the inside and outside of the air conditioning unit and reducing effective energy loss. In addition, reinforcing ribs are provided in the inner frame, thereby increasing the strength of the frame. Attached Figure Description
