Embodiment Construction
[0013] The present invention will be described below in conjunction with the drawings:
[0014] A direct air cooling system fan inlet shutter includes a direct air cooling system fan barrel 2, a fan 10 is arranged in the direct air cooling system fan barrel 2, and an air cooling triangle 1 is set above the direct air cooling system fan barrel 2, An umbrella-shaped frame 4 is provided on the bottom port 3 of the air-cooling system fan cylinder 2, and a plurality of ball bearings 6 are arranged at equal intervals on each umbrella-shaped frame. The ball bearings 6 on two adjacent umbrella-shaped frames are two Two symmetrically arranged, each pair of symmetrically arranged ball bearings 6 is provided with a rotating shaft 5, the rotating shaft 5 is fixedly connected to one side of the trapezoidal louver 8, and a hinge 11 is provided on the movable side of the trapezoidal louver 8. The trapezoidal louver blades 8 located on the same fan-shaped area are hinged to the trapezoidal louv...

The invention provides a fan inlet louver of a direct air cooling system to solve the problems in the prior art that the deep load changing of a heat supply machine set in winter cannot be solved and an air cooling system cannot be prevented from freezing. An air cooling triangle (1) is arranged above a fan cylinder body (2) of the direct air cooling system, umbrella-shaped skeletons are arrangedon a bottom port (3) of the fan cylinder body (2) of the direct air cooling system, a plurality of ball bearings (6) are equidistantly arranged on each umbrella-shaped skeleton, every two ball bearings (6) on two adjacent umbrella-shaped skeletons are arranged in a symmetrical manner, rotating shafts (5) are arranged in each pair of symmetrically arranged ball bearings (6), the rotating shafts (5) are fixedly connected with one side of a trapezoidal louver leaf (8), and the trapezoidal louver leaves (8) arranged on the same sector region are hinged with trapezoidal louver leaf connecting rods(9) through hinges (11). The fan inlet louver disclosed by the invention is simple in structure and is economical and practical.
Description
Technical field [0001] The invention relates to a fan duct of a direct air cooling unit, in particular to a [0002] The cover of the fan duct of the direct air cooling unit. Background technique [0003] The air condenser of the direct air cooling system is arranged in the ambient atmosphere, and its performance and safety are greatly affected by environmental factors. Especially in the cold winter in the north, the ambient temperature is lower than 0 ℃, and it is easy to freeze. The lighter ones will greatly reduce the heat transfer performance of the air condenser and increase the heat consumption. The heavy ones will block the tube bundles with ice, reduce the vacuum and be forced to shut down, or even freeze the finned tubes or deform the finned tubes, resulting in permanent Therefore, it is necessary to prevent freezing of direct air cooling systems in cold areas. The main cause of freezing is that the amount of steam entering the air cooling system is too low. At present,...
