Abstract: Disclosed are a cooling water-saving device for a cooling tower, and a wet cooling tower. The cooling water-saving device includes indirect heat exchange devices and a water collecting tank. The inner wall of a cooling tower shell is sealed by the water collecting tank. The indirect heat exchange device includes a heat exchange channel and a heat insulation channel. The heat insulation channel penetrates through the bottom of the water collecting tank, and the bottom inlet of the heat insulation channel communicates with air entering from the bottom of the cooling tower shell. The heat exchange channel for shielding water drops is arranged at the top outlet of the heat insulation channel, and the top of the heat exchange channel extends into an air outlet in the upper part of the cooling tower shell. The lower outlet of the heat exchange channel communicates with a rain area.
