Description

Technical Field

[0001] The utility model relates to the technical field of cooling towers, in particular to a temperature control device for circulating water in a closed countercurrent cooling tower. Background Art

[0002] A cooling tower is a device that dissipates the heat generated during industrial production or refrigeration processes into the atmosphere, bringing the heat-carrying medium into full contact with the air or other media for heat exchange, thereby achieving a cooling effect. Traditional YBN counterflow closed cooling towers will discharge a large amount of steam into the atmosphere along with the gas during cooling, and the heat exchange is uneven and cannot fully dissipate the heat.

[0003] A Chinese patent with publication number CN112815738A has been proposed in the prior art to solve the above-mentioned technical problems. The technical solution disclosed in the patent document is as follows: The present invention discloses a YBN countercurrent closed cooling tower, comprising a cooling tower shell, the cooling tower shell is in a bottle-mouth shape, and an air outlet is opened on the top of the cooling tower shell, and a motor connected to a power supply is welded to the inner wall of the air outlet through a bracket, and a hole is opened on the upper half of the cooling tower shell from the front and rear ends of the side wall, and a cooling pipe is inserted into the hole.

[0004] Although the device can effectively cool the liquid, the cooling tower cannot lower the temperature of the water to a level lower than the temperature of the liquid in the pipe, because this will cause ice to form inside the cooling tower. If hot water cannot be sprayed regularly, the cooling effect of the cooling tower will be affected, and the water distribution in the cooling tower may be uneven, thereby affecting the operating efficiency of the entire system, resulting in the normal operation of the equipment being affected by the freezing of water and the inability of the device to spray the cooling tower regularly.
