Description

Technical Field

[0001] The utility model belongs to the technical field of power distribution cabinets, and in particular relates to a heat dissipation structure of a power distribution cabinet. Background Art

[0002] A power distribution cabinet is an electrical device that is mainly used for the distribution, control and protection of power transmission and distribution systems. It is widely used in substations, factories, commercial buildings, residential areas and other places. At present, when using power distribution cabinets, special power distribution cabinet heat dissipation structures are required for heat dissipation.

[0003] The existing heat dissipation structure of the distribution cabinet usually installs a cooling fan inside or outside the distribution cabinet. The relatively low-temperature air outside is introduced into the cabinet through the forced air flow generated by the operation of the fan, and the high-temperature air accumulated inside is discharged at the same time, thereby establishing an efficient air convection circulation system to achieve the heat dissipation purpose. However, in actual application scenarios, even if the fan forced convection heat dissipation method is adopted, for some high-heat-generating electrical components, relying solely on the airflow driven by the fan for heat dissipation may not be sufficient. Especially in the case of long-term high-intensity operation, the temperature of some core electrical components rises sharply due to continuous heat generation. The heat dissipation effect of the airflow formed by the fan alone may be relatively limited, and it is difficult to ensure that such components can operate stably and permanently within the ideal operating temperature range. Utility Model Content

[0004] In view of this, the utility model provides a heat dissipation structure for a distribution cabinet, which can accurately guide cold air to the heating elements in the distribution cabinet through a directional heat dissipation mechanism, thereby realizing effective cooling of local hot spots in the distribution cabinet. The angle and height of a certain directional heat dissipation sleeve can be individually adjusted according to the position of the electrical component that needs to be focused on heat dissipation, so as to accurately point to the electrical component that needs to be focused on heat dissipation, maintain the directional heat dissipation state and stability of the directional heat dissipation sleeve, and meet the directional heat dissipation requirements of heating elements at different positions in the distribution cabinet.
