The invention relates to a column type cooling pipe bundle with a wedge-shaped gap. The column type cooling pipe bundle comprises two fin type radiating pipe bunches, wherein the ends of the two fin type radiating pipe bunches are crossed by a set angle while the other ends of the two fin type radiating pipe bunches are open; a wedge-shaped gap is formed between the two fin type radiating pipe bunches; the pipe bunches, taking the crossed point of the two radiating pipe punches as an original point, extend towards the open sides with a certain distance 1; the two radiating pipe bunches share the same fin within the distance of 0-1, wherein the distance 1 is less than half of the spacing of the two sides of the pipe bunches. An air flow field structure of a cooling unit can be optimized through the air from the wedge-shaped gap of the column type cooling pipe bundle; when the air flows to a louver of the vertical cooling unit, fresh air can be guided to the interior of the cooling pipe bunches directly so as to improve the average heat transfer temperature difference of the cooling pipe bunches and reinforce the heat transfer of the cooling pipe bunches; when the air flows in an inclined manner, the internal space of the cooling unit is impacted by the air from the wedge-shaped gap, so that the low-speed air eddy region of the cooling unit can be reduced, the cooling performance of the pipe bunch at one side of the cooling unit and the cooling performance of the overall cooling unit are improved, finally the cooling performance of a cooling tower is improved.
