The invention provides a heat dissipation device and an air cooling system with the same. The heat dissipation device comprises a plurality of heat-dissipating finned tubes arranged in parallel, one ends of the heat-dissipating finned tubes communicate with a steam distributing tube, and the other ends of the heat-dissipating finned tubes communicate with condensate water pipelines respectively; and the heat dissipation device further comprise air flow adjusting assemblies which cover the outer sides of the tube walls of the heat-dissipating finned tubes retractably so as to adjust the ventilation areas of the heat-dissipating finned tubes. According to the heat dissipation device which applies the technical scheme, the ventilation area of each heat-dissipating finned tube can be adjusted according to the temperature of the environment in which the heat dissipation device is, so that the phenomenon that the heat-dissipating finned tubes are frozen when the environment temperature is lower than 0 DEG C is avoided; and meanwhile, when the environment temperature is high, the airflow can uniformly act on the heat-dissipating finned tubes to improve the heat-dissipating capacity.
Description
technical field [0001] The invention relates to the field of cooling equipment, in particular to a heat dissipation device and an air cooling system having the same. Background technique [0002] The direct air cooling system is the main heat dissipation equipment of the steam turbine unit in the air cooling power plant. The direct air cooling system is composed of several rows of A-shaped heat sinks, such as figure 1 As shown, each row of A-shaped cooling devices includes a steam distribution pipe 1, two condensate water pipes 2 and several cooling units, each cooling unit is separated and closed by a partition wall 4, and each cooling unit is composed of several cooling fin tubes 3 components such as figure 2 As shown, the heat dissipation finned tubes 3 on each heat dissipation unit are divided into two groups, and the two groups of heat dissipation finned tubes 3 are arranged at an angle of 60° to each other, and the upper ends of the two groups of heat dissipation fin...
