Description

Technical Field

[0001] This utility model discloses a cooling tower structure, belonging to the field of cooling tower technology, specifically relating to a multi-condition energy-saving cooling tower. Background Technology

[0002] Traditional cooling towers typically employ a fixed air intake structure, designed based on constant operating conditions. Heat exchange between air and circulating water is achieved through sidewall louvers or an open bottom intake. While this structure is highly efficient under rated load, it suffers from significant drawbacks in actual operation: 1. A fixed-opening air intake channel cannot adapt to changes in ambient temperature, humidity and load, resulting in insufficient airflow at low loads leading to heat recirculation, or excessive resistance at high loads causing fan surge. 2. Unilateral air intake can easily cause uneven airflow distribution inside the tower, resulting in a "short-circuit flow" phenomenon in the packing area, which reduces heat exchange efficiency by 10%-20%. 3. Excessive cold air intrusion during winter operation can lead to icing, while forcibly closing some air inlets can cause the fan's energy consumption to soar.

[0003] The aforementioned problems cause the annual average coefficient of performance (COP) of traditional cooling towers to be typically below 3.0 under varying operating conditions, and additional antifreeze heating devices are required, increasing operation and maintenance costs. Utility Model Content

[0004] Purpose of the utility model: To provide a multi-condition energy-saving cooling tower to solve the problems mentioned above.

[0005] Technical solution: A multi-condition energy-saving cooling tower, comprising: tower body, air inlet grille assembly, packing, cooler, fan and circulating pump; In a further embodiment, the air inlet grille assembly is installed inside the tower body, the fan is fixedly installed on the top of the tower body and connected to the tower body, the packing and the cooler are installed inside the tower body, with the packing located above the cooler, and the circulating pump is located outside the tower body and connected to the inlet and outlet of the cooler through a pipe.

[0006] In a further embodiment, the air intake grille assembly includes: a first air intake grille, a second air intake grille, a third air intake grille, a fourth air intake grille, and a fifth air intake grille; The interior of the tower is divided into a water collection zone, a packing zone, and a cooling zone from top to bottom; The first air inlet grille is installed inside the tower body and located between the water collection area and the packing area; the second air inlet grille is installed inside the tower body and located between the cooling area and the packing area; the third and fourth air inlet grilles are installed on one side of the tower body and connected to the cooling area; and the fifth air inlet grille is installed on the other side of the tower body and connected to the cooling area.

[0007] In a further embodiment, a water collector is provided in the water collection area, and the water collector is connected to the circulating pump through a pipe.

[0008] This utility model of a multi-inlet grille cooling tower achieves energy saving under multiple operating conditions by optimizing airflow organization. It employs a zoned, controllable three-dimensional grille design, and its beneficial effects include: 1. By balancing the airflow distribution within the tower through multi-directional air intake, eddy current losses are reduced, thereby increasing the heat exchange efficiency of the packing material by 15%-25%; 2. Adaptable to multiple operating conditions, reducing fan power consumption by 30%-40% during partial load operation; 3. The modular grid structure also has the function of preventing water drift. Under the premise of water vapor ratio ≤0.01%, the annual comprehensive energy efficiency ratio (COP) can reach more than 4.2, which is especially suitable for applications in areas with large diurnal temperature differences or significant seasonal load fluctuations.
