Enclosed type cabinet for use in machine room

Disclosed is an enclosed type cabinet for use in a machine room. The cabinet is of a cylindrical structure and composed of a plurality of arc-shaped auxiliary cabinets. A plurality of arc-shaped auxiliary frames are combined to form each auxiliary cabinet in an annular shape. The arc-shaped auxiliary frames are provided with board clamping slots and auxiliary frame back plates. Vertical blowers are arranged in the centers of the arc-shaped auxiliary cabinets. The bottom ends of the arc-shaped auxiliary frames are communicated with a cold air channel arranged under the floor. Air outlets of the vertical blowers are connected with a hot air channel on the ceiling. Through enclosed type sealing process on the cabinet and the outer space, a hot air zone is limited in the cabinet due to concentrated cooling of the vertical blowers, in this way a cold air zone is further isolated from the hot air zone, thus higher refrigerating efficiency and better energy saving effect are achieved to increase ...
