Diversion device for environmental wind outside vertically arranged air-cooled radiator of indirect air cooling system

Abstract

The invention discloses a diversion device for environmental wind outside a vertically arranged air-cooled radiator of an indirect air cooling system, and belongs to the field of power station cooling systems. The diversion device for the environmental wind consists of six diversion flat plates which are uniformly distributed on the periphery of the windward side of the air-cooled radiator to form a fan shape, wherein the diversion flat plates have an equal height; the tops of the diversion flat plates are parallel to the upper edge of a cooling triangle of the air-cooled radiator; the widthsof the diversion flat plates are sequentially gradually decreased from the far end to near end of a wind field; and the diversion flat plates keep a certain identical distance away from the inlet surface of the cooling triangle of the air-cooled radiator. By the diversion device for the environmental wind field outside the air-cooled radiator, after oncoming transversal wind which flows approximately in parallel from the air-cooled radiator is diverted by the diversion flat plates, the pressure of air at an inlet of the cooling triangle is increased, and the air enters the air-cooled radiatorin a direction approximately vertical to the inlet surface of the cooling triangle, thereby making the cooling air flow of the cooling triangle in different sector more uniform and improving the radiation performance of the air-cooled radiator.

Description

technical field [0001] The invention belongs to the field of power station cooling systems. In particular, the utility model relates to a vertically arranged air-cooling radiator external environment wind guiding device for an indirect air cooling system. Specifically, the deflector plates of different sizes arranged in a fan shape at the inlet of the cooling triangle of the air-cooled radiator are used to guide the ambient wind field outside the air-cooled radiator, so as to realize the rational use of the energy of the ambient wind field, reduce the back pressure of the air-cooled unit, and weaken the wind field Adverse effects on the performance of air-cooled radiators, improving the performance of indirect air-cooled systems. Background technique [0002] Indirect air cooling, as one of the cooling forms of power stations, has achieved rapid development in my country in recent years. The air-cooling radiator of the indirect air-cooling system has two arrangements, one ...
