The utility model relates to a take spinning cooling device of guide plate, it mostly influences the spinning cooling effect to solve spinning cooling device amount of wind undersize or cross, the difficult problem of amount of wind control. Its characterized in that is walked including the cooling channel of vertical setting, spinning from the top down in cooling channel to this device: one side of cooling channel sets up the air -supply line, is equipped with in the air -supply line to separate the guide plate that becomes to go up wind channel and lower wind channel with the air -supply line, and the entrance point cross -section of going up the wind channel is lighter than the exit end cross -section, and the entrance point cross -section in lower wind channel is greater than the exit end cross -section. The utility model discloses a guide plate forms the ladder air inlet with cooling device's air -supply line layering, bonds in the reduction spinning cooling process, guarantees the spinning cooling effect.
