Description

Cold accumulation control device for virtual power plant Technical Field The utility model relates to the technical field of control devices, in particular to a cold accumulation control device for a virtual power plant. Background In virtual power plants and various high density power electronics cabinets, the thermal load generated during operation is concentrated in the top region of the module, while the bottom temperature is relatively low, resulting in severe temperature stratification within the cabinet. The long-term temperature gradient not only affects the heat dissipation efficiency of equipment in the cabinet, but also accelerates the aging and failure of electronic components, and reduces the reliability and service life of the system. The common cooling mode of the cabinet at present mainly depends on a single fan or a combination of a plurality of fans, cold air is blown into the cabinet body from a fixed air outlet, and then hot air is discharged from a top or side air return opening. The problem that the air at the upper layer and the lower layer cannot be effectively mixed due to unidirectional convection, local overheating and poor temperature uniformity caused by air duct resistance and dead angle positions still remain to be difficult to solve. Meanwhile, in order to pursue a more forced cooling effect, the rotating speed of the fans has to be increased or the number of the fans is increased, so that the energy consumption is greatly increased. Disclosure of utility model The utility model aims to solve the problems of serious internal temperature layering, uneven heat dissipation, higher energy consumption and the like of a cabinet in the prior art, and provides a cold accumulation control device for a virtual power plant, which can intelligently regulate internal airflow and realize uniform and efficient heat dissipation. In order to achieve the above purpose, the present utility model provides the following technical solutions: a cold storage control device for a virtual power plant, comprising: the machine cabinet comprises a machine cabinet body, wherein a lower air port is arranged at the lower edge of the machine cabinet body, an upper air port is arranged at the upper edge of the machine cabinet body, and fans are arranged in the upper air port and the lower air port. An air flow disturbance component acting on the upper air port and the lower air port is arranged in the cabinet main body. The airflow disturbance assembly comprises a first baffle and a second baffle, and both the first baffle and the second baffle are hinged with a driving connecting rod and an auxiliary connecting rod. The airflow disruption assembly further includes a carriage. The driving device is characterized in that a driving piece is slidably arranged on the sliding frame, a sliding groove is formed in the driving piece, a sliding part is arranged on the driving connecting rod, and the sliding part is matched with the sliding groove. The driving connecting rod and the auxiliary connecting rod are hinged with the sliding frame. The first baffle plate and the second baffle plate are provided with a plurality of overflow holes, and are provided with refrigerating pieces. As a preferable scheme, a driving air cylinder is fixed on the sliding frame, the movable end of the driving air cylinder is fixedly connected with the driving piece, and the driving piece is driven to slide through the expansion and the contraction of the air cylinder.
