Title:
COLUMN TYPE COOLING TUBE BUNDLE WITH WEDGE-SHAPED GAP
Document Type and Number:
WIPO Patent Application WO/2016/169076
Kind Code:
A1
Abstract:
A column type cooling tube bundle with a wedge-shaped gap (12), comprising two fin type radiating tube bundles (13, 14), the ends of the two fin type radiating tube bundles being crossed at a set angle, the other ends being open. A wedge-shaped gap (12) is formed between the two fin type radiating tube bundles (13, 14). The tube bundles extend, by taking a crossed point of the two radiating tube bundles (13, 14) as an original point, towards the open sides by a certain distance 1, so the two radiating tube bundles (13, 14) share the same fin within the distance of 0 to 1, wherein the distance 1 is smaller than half of an interval between the two sides of the tube bundles. An air flow field structure of a cooling unit can be optimized by means of air from a wedge-shaped gap (12) of the column type cooling tube bundle; when the air (11) flows into a louver of a vertical cooling unit, fresh air can be guided into cooling tube bundles directly, thereby improving the average heat transfer temperature difference of the cooling tube bundles, and reinforcing heat transfer of the cooling tube bundles; and during the inclined inflow of the air (11), an internal space of the cooling unit is impacted by the air from the wedge-shaped gap (12), such that a low-speed air eddy region in the cooling unit can be reduced, the cooling performance of the tube bundle at one side in the cooling unit and the cooling performance of the overall cooling unit are improved, and the cooling performance of a cooling tower is improved finally.
