Abstract

The invention discloses an adjustable ventilation device and a control system therefor. An air regulation apparatus is fixed on a floor support, and a ventilation floor is laid on a square frame. The square frame is provided with wind shield plates and movable wind shield plates, and ventilation gaps in a horizontal direction are respectively formed between the adjacent two wind shield plates. Inner sides, at which two ends of each wind shield plate are located, of two frames are respectively provided with a guide rail in a length direction. Two ends of each movable wind shield plate are respectively disposed on guide rails of the two frames in a sliding manner. The movable wind shield plates are respectively in fixed connection with the same connecting plate, and the width of each ventilation gap between two adjacent wind shield plates is less than or equal to the width of each movable wind shield plate. The lower side of a strip-shaped connecting plate is provided with racks in the length direction of the guide rail, and a gear is engaged with the racks. A torsional force steering engine drives the gear to rotate, so as to solve a problem that the effect of a convention air supply system is not ideal because a conventional ventilation floor structure is not reasonable and the ventilation cannot be changed easily. The invention belongs to the field of cabinet temperature control.

Description

technical field

[0001] The invention relates to a ventilation device and a control system thereof, belonging to the field of cabinet temperature control. Background technique

[0002] At present, in the computer room of the power system, in order to prevent the temperature of the equipment in the cabinet from being too high, each cabinet is equipped with a cooling system. The ventilation system supplies air to the cabinet through the ventilation floor of each cabinet to achieve the purpose of cooling the equipment in the cabinet and prevent the equipment in the cabinet from generating harmful gases and particles due to heat. However, the existing unified air supply method is based on the design It is necessary to supply air to almost all the cabinets in the computer room, and the existing ventilation floor only has ventilation holes, and the size of the ventilation holes is fixed, so the ventilation volume cannot be adjusted. In actual use, there may be some cabinets in the ...
