Description

Technical Field

[0001] The utility model relates to the field of cooling towers, in particular to a redundant cooling tower water cooling system. Background Art

[0002] A cooling tower is a device that uses water as a circulating coolant, absorbing heat from a system and discharging it into the atmosphere to lower the water temperature. Traditional water-cooled towers spray hot water on the surface of the filler, allowing the air and water to fully contact. Under the action of the fan, part of the water evaporates and part of it drifts away in the wind in the form of small droplets. Since the device is generally barrel-shaped, it is called a cooling tower.

[0003] A Chinese utility model (publication number: CN219757036U) discloses an energy-saving cooling tower, including a bellows, a pump is fixedly connected to the bottom of the bellows, a water inlet is fixedly connected to the pump port of the pump, a nozzle is fixedly connected to the outer wall of the water inlet, the bottom of the bellows is fixedly connected to a water tank, a filler is fixedly connected to the inner wall of the water tank, and the bottom of the water tank is fixedly connected to a base. When the bellows is sucking air during water cooling, the water tank circulates through the ventilation slots on the base, and the air is filtered through the filter net during the suction process. After filtering, the water enters the water tank for water cooling. At the same time, when draining, the cooling water is guided into the drain pipe by the trapezoidal plate for rapid drainage. When in use, the water is quickly guided through the trapezoidal plate of the base. At the same time, when air cooling is performed, the air is filtered through the filter net, which can effectively filter the air.

[0004] It is found that there are at least the following problems in this technology: the cooling tower water cooling system of the above-mentioned patent is only provided with one water pump, so the water pump is prone to failure due to continuous operation, and once the water pump fails, the entire water cooling system will lose circulation power, resulting in the entire main converter cabinet being unable to cool normally or overheating, and even causing the entire electric locomotive traction drive system to fail to work normally. Therefore, a redundant cooling tower water cooling system is now proposed. Utility Model Content

It can increase the heat dissipation, extend the cooling water residence time, increase the heat exchange area and heat exchange, and evenly distribute water.

[0021] As a further solution of the utility model, a base is fixedly installed at the bottom of the cooling tower body.

[0022] By adopting the above technical solution, the base is used to fix the cooling tower body.
