Description

Technical Field

[0001] The utility model relates to the technical field of cooling towers, in particular to a high-efficiency counter-flow cooling tower. Background Art

[0002] A cooling tower is a device that cools hot fluid to a reasonable temperature. The filler is the most important part of a cooling tower. Its efficiency depends on the degree of full contact between the cooling water and the air in the filler. The cooling tower filler is usually formed by bonding multiple cooling tower filler sheets. The main function of a cooling tower is to exchange heat with the cooling water carrying waste heat inside the tower body, so that the waste heat is transferred to the air and dissipated into the atmosphere. The characteristic of a counterflow cooling tower is that the water flows vertically in the tower, and the airflow direction is opposite to the water flow direction.

The utility model discloses an efficient and energy-saving natural ventilation countercurrent cooling tower, including a cooling tower with openings at both ends, an air outlet pipe is fixedly connected to the outer wall of the cooling tower near the upper end, one end of the air outlet pipe extends through the cooling tower and is fixedly connected to a heat exchange pipe, and an air inlet pipe is fixedly installed on the outer wall of the cooling tower directly below the air outlet pipe. The beneficial effect of the utility model is that when in use, hot air is injected into the connecting cavity through the air inlet pipe, and the hot air impacts on the blades, so that the blades can drive the connecting cylinder to rotate, and the connecting cylinder can drive the mounting ring to rotate through the meshing of the driving gear and the gear ring, and the mounting ring will drive the fan blades to rotate, and when the fan blades rotate, air will be drawn from the bottom opening of the cooling tower and blow air to the heat exchange pipe to perform heat exchange operations, thereby making the natural ventilation cooling tower more efficient.
