[0002] The cooling triangle unit is a key component in air-cooling towers that handles waste heat from cold-end units. It is increasingly being used in thermal power plants in my country's "Three Norths" region. However, due to the high winds (wind speeds exceeding 4m / s) experienced in these areas for extended periods of the year, crosswinds can easily cause lateral vortices to form within the cooling triangle unit, leading to hot air recirculation. Furthermore, lateral vortices on the leeward side of the guide device on the outer side of the cooling triangle unit can reduce the cooling performance of the cooling columns on the left and right sides of the downstream air flow field, impacting the cooling performance of the air-cooling tower.

Figure 2 As shown in FIG), it includes a cooling triangle unit and a flow guide device with a jet function that can eliminate transverse vortices. Based on the flow guide device with a jet function that can eliminate transverse vortices, on the basis of optimizing the air inlet volume on the left and right sides of the cooling triangle, the multi-stage jet formed by the multi-stage jet gap can effectively eliminate the transverse vortex on the leeward side of the flow guide device outside the cooling triangle unit (as shown in FIG).
