Description

Technical Field

[0001] This utility model relates to the field of cooling tower technology, specifically to an intelligent temperature control device for cooling towers. Background Technology

[0002] A cooling tower is a device used in industrial, construction, or power plant settings. Its main function is to reduce the temperature of hot water or steam by exchanging air with water, thereby facilitating heat exchange and dissipation. The core function of a cooling tower is to remove heat from water. It is commonly used in equipment or systems that require a large amount of heat dissipation, such as air conditioning systems, power plants, chemical plants, and oil refineries.

[0003] In order to ensure that the cooling tower can operate efficiently and stably under different operating conditions, an intelligent temperature control device for the cooling tower is required to precisely control and adjust the cooling tower water temperature.

[0004] In the process of developing this utility model, the inventors discovered the following problems with the existing technology: 1. Some existing intelligent temperature control devices for ordinary cooling towers typically rely on only one fan to directly blow the water in the cooling tower to cool it down when performing water temperature reduction operations. This single-fan air-cooling mode has low cooling efficiency and is difficult to achieve the ideal cooling effect, resulting in the cooling tower's water temperature being difficult to drop to the target range quickly and stably during actual operation; 2. Some existing intelligent temperature control devices for ordinary cooling towers typically rely on only air cooling when performing water temperature reduction operations. This single cooling method greatly limits the efficiency of the cooling system, resulting in the cooling tower's water temperature being difficult to drop to the target range quickly and stably during actual operation, seriously affecting the cooling effect and making it difficult to meet the cooling needs under complex working conditions.

To achieve the above objective, this utility model provides the following technical solution: an intelligent temperature control device for cooling towers, comprising a liquid inlet assembly, wherein a water-cooling assembly, a first air-cooling assembly, and a second air-cooling assembly are installed on the inner wall of the liquid inlet assembly.

[0006] The liquid inlet assembly includes a base plate, with support rods installed at the four corners of the top of the base plate. An mounting plate is installed on the top of each support rod. Several support rods are installed on the top of the base plate. A first spiral tube and a second spiral tube are installed on the outer wall of each support rod. A liquid outlet pipe is installed at one end of the first spiral tube, and a liquid inlet pipe is installed at the other end of the first spiral tube.

[0007] The water-cooling assembly includes a water pump installed on the top of the base plate. A connecting pipe is installed at the outlet end of the water pump. An annular pipe is installed at one end of the connecting pipe. Several spray pipes are installed at the bottom of the outer wall of the annular pipe.

Combined with the first and second air-cooling components, the efficiency of the cooling system is improved, so that the water temperature in the cooling tower drops to the target range quickly and stably, thus improving the cooling effect.

The water pump 201 starts and pumps the coolant. The coolant enters several spray pipes 204 and several...
