Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of cabinet cold aisle, especially to a cabinet cold aisle device. BACKGROUND

[0002] In the prior art, as an important temperature control facility in data centers or server rooms, the main function of the cabinet cold aisle is to improve cooling efficiency by isolating the flow of cold and hot air. However, in practical applications, in order to further improve its thermal insulation effect and ensure the stability of the temperature in the cold aisle, it is usually necessary to install an insulation layer around the cabinet cold aisle. The presence of such an insulation layer plays a crucial role in preventing external heat from penetrating into the cold aisle and preventing the loss of cold air in the cold aisle to the external environment. Despite this, the existing cabinet cold aisle has certain limitations in terms of installing and removing the insulation layer. This mainly manifests in two aspects: First, the complexity of the installation process. The existing insulation layer design may not be flexible enough or fully compatible with the structure of the cabinet cold aisle, resulting in the need for additional time and labor during installation, and even the need for professional tools or the intervention of professional personnel. This complexity not only increases the installation cost, but also prolongs the installation time, affecting the overall efficiency of use. Second, the inconvenience of the disassembly process. When maintenance, upgrading or cleaning is required, the disassembly of the insulation layer may also face difficulties.
