Description

Technical Field

[0001] The utility model relates to the technical field of air conditioner outdoor units, in particular to an internal bracket component and an air conditioner outdoor unit. Background Art

[0002] At present, the fixing method of the air conditioner outdoor unit condenser is to fix it with sheet metal on the left and right sides or to fix it with copper tube fixing clip + right side sheet metal. Fixing with sheet metal on the left and right sides affects production efficiency, and it is also necessary to insert tubes and expand tubes; when fixing with copper tube fixing clips, if the transportation conditions are poor, the copper tube fixing clips are easy to fall off the condenser due to vibration. In addition, the fixing parts of single-row condensers and double-row condensers are not universal, which increases the complexity of materials. In order to solve this technical problem, the Chinese Utility Model (Authorization Announcement No.: CN 215929891 U, Authorization Announcement Date: 2022.03.01) discloses an air conditioner outdoor unit and its condenser fixing structure. In this scheme, the limiter has multiple fixed installation positions, which can adapt to condenser assemblies of different sizes and specifications, as well as single-row condensers and double-row condensers. At the same time, it can reduce screw fixing, improve production efficiency, and reduce production complexity.

[0003] Although the condenser installation structure of this scheme is simple in design and conducive to assembly efficiency, the limited installation of the condenser is not stable and reliable enough because it is only initially fixed by the limit parts. During actual work use, due to the high power and speed of the air conditioner outdoor unit fan, if the components of the outdoor unit are not installed firmly enough, it will often produce large vibration noise.
