Description

Technical Field

[0001] The utility model relates to the technical field of cooling tower structures, in particular to a single-inlet composite-flow closed cooling tower. Background Art

[0002] A cooling tower is a device that uses water as a circulating coolant to absorb heat from a system and discharge it into the atmosphere to lower the water temperature. It uses the heat exchange between water and air to produce steam. The steam evaporates and takes away the heat to achieve evaporative heat dissipation, convection heat transfer, and radiation heat transfer. It is an evaporative heat dissipation device that dissipates the waste heat generated in industry or refrigeration and air conditioning to lower the water temperature to ensure the normal operation of the system. The device is generally barrel-shaped, hence the name cooling tower;

[0003] For example, the Chinese authorized patent (new cooling tower) with announcement number CN217585391U includes a frame, a cooling tower body, an exhaust device, a spray device, a filler bracket and a water collecting tank; the cooling tower body is provided with a water inlet connected to the spray device and a water outlet connected to the water collecting tank, and the side of the cooling tower body is provided with an air inlet; the exhaust device is installed in the opening at the top of the cooling tower body; the spray device is provided with multiple spray ports; the filler bracket is at least one layer, and the multiple layers of filler brackets are arranged at intervals along the height direction of the cooling tower body for fixing the cooling filler, and the number of layers of the filler bracket can be adjusted according to the volume and weight of the cooling filler to adapt to the cooling filler. When it is necessary to adjust the number of layers of the filler bracket according to the volume and weight of different cooling fillers, the structure of the filler bracket can be adjusted according to the volume and weight of the cooling seasoning, and at the same time, the cooling filler is well fixed, thereby improving the utilization rate and practicality of the filler bracket.

[0004] However, the cooling device in the cooling tower in the above-mentioned prior art is relatively simple, and its efficiency is not good during cooling operation, thereby affecting the heat exchange efficiency of the cooling tower; therefore, it does not meet the existing needs. We have proposed a single-inlet composite flow closed cooling tower. Utility Model Content

[0005] The utility model aims to provide a single-inlet composite flow closed cooling tower to solve the problem that the cooling device in the cooling tower in the prior art proposed in the above background technology is relatively single and its efficiency is poor during cooling operation, thus affecting the heat exchange efficiency of the cooling tower.

[0006] To achieve the above object, the utility model provides the following technical solution: a single-inlet composite flow closed cooling tower, comprising a cooling tower, both end faces of the cooling tower are provided with panels, one side of the upper surface of the cooling tower is provided with a first inspection door, and one side of the front end face of the cooling tower is provided with a second inspection door;

[0007] Also includes:

[0008] A wind tube is arranged on the other side of the upper surface of the cooling tower, and two wind tubes are provided, the upper surfaces of the two wind tubes are both installed with grid plates, a motor is installed inside the wind tube, and a fan is installed at the bottom of the motor;

[0009] A spray pump is arranged on the other side of the front end face of the cooling tower. A connecting pipe is installed on the spray pump. A water inlet pipe is arranged on one side of the connecting pipe, and a water outlet pipe is arranged on the other side of the connecting pipe.

[0010] Preferably, a packing rack is provided inside an end surface of one side of the cooling tower, and three packing racks are provided.

[0011] Preferably, a water collecting tank is provided below the filling rack.

[0012] Preferably, a spray mechanism is provided at the top of the interior of the cooling tower, and a connecting frame is provided on the upper surface of the spray mechanism.

[0013] Preferably, a spray pipe is provided at the bottom of the connecting frame, and three spray pipes are provided, and a spray head is provided at the bottom of the three spray pipes.

[0014] Preferably, a plurality of the spray heads are provided.

[0015] Preferably, a cooler is provided below the spray mechanism, a cooling pipe is provided inside the cooler, and a plurality of cooling pipes are provided.

[0016] Compared with the prior art, the beneficial effects of the utility model are:

[0017] 1. The utility model arranges a spray mechanism and a cooler inside the cooling tower. The spray mechanism is arranged above the cooler. Air enters through one side of the filler frame and is then discharged from the air duct after passing through the cooler. The cooler utilizes an inlet pipe and an outlet pipe to circulate the cooling pipe inside the cooler. At the same time, the spray pump transports water to the spray pipe through a connecting pipe and sprays the water through a spray head, so that the outer wall of the cooler is completely wetted. At the same time, soft water is used for the water circulation, which does not scale or block the pipeline, thus avoiding the formation of scale at dry points and improving the efficiency to the maximum extent. This solves the problem that the cooling device in the cooling tower in the prior art is relatively single and its efficiency is poor during cooling operation, thereby affecting the heat exchange efficiency of the cooling tower.

[0018] 2. By adopting the composite flow cooling method, the cooling medium is closed and circulated, and no impurities enter, ensuring the purity of the medium. The cooling tower occupies a small area and can be moved and placed as needed, with low maintenance costs. The composite flow closed cooling tower is an anti-freeze and energy-saving cooling tower. When the equipment is not running at low temperatures, the water in the cooler automatically flows back to ensure that the equipment is not frozen, and the water generated during spraying is collected through the water collection tank for easy recycling.
