Background
The indirect air-cooling radiator is a main part of an indirect air-cooling system of a thermal power station, and is used as a heat exchange device for cooling circulating cooling water from equipment such as a turbine condenser. A common indirect air-cooled radiator is also called a cooling delta, and each cooling delta is composed of two cooling columns (each cooling column comprises a plurality of tube bundles), and the two cooling columns are vertically arranged and form a certain included angle.
The cooling column is formed by connecting a plurality of tube bundles into a whole. The tube bundle is a basic unit of the indirect air cooling radiator and mainly comprises a tube plate, a heat exchange tube and fins. The tube plates are positioned at two end parts of the tube bundle, the tube plates are connected with the heat exchange tubes in an expansion joint mode, the heat exchange tubes are round tubes with round sections, the fins are plate fins, and the heat exchange tubes and the fins are also connected in an expansion joint mode in order to eliminate gaps between the heat exchange tubes and the fins and reduce thermal resistance. When the indirect air cooling radiator works, circulating cooling water flows in the heat exchange pipe, air flows out of the heat exchange pipe, and the circulating water is cooled through convection heat exchange.
The existing indirect air cooling radiator pipe bundle has the defects that: because of the influence of vortex formed when air passes through the round tube heat exchange tube, the indirect air cooling radiator tube bundle has lower heat exchange efficiency and larger air side resistance.
