Description

Technical Field

[0001] The utility model relates to the field of cooling towers, in particular to a temperature reduction cooling device used in cooling towers. Background Art

[0002] The function of the cooling tower's cooling device is to transfer the heat in the hot medium to the cooling medium by transferring heat, thereby achieving a cooling effect. In the cooling tower, the cooling device can effectively reduce the temperature of the working medium in the cooling tower to ensure that the system operates within a safe and stable temperature range.

[0003] In order to ensure the stability of system operation, it is necessary to use the cooling tower's cooling device to dissipate heat for the working medium. For example, the prior art Chinese patent announcement number "CN105509542B" discloses a cooling device, including a body, a central axis running through the middle of the body, a vortex bearing linked to the body is arranged between the central axis and the body, the outer periphery of the body is evenly distributed with a number of blades linked to the body along its circumference, and the middle of the body has a vortex water chamber connected to the cooling tower water pipe; a number of spray bars extending along the radial direction of the body are arranged above the blades, and each spray bar is evenly distributed on the outer peripheral surface of the body in turn along the circumference of the body, and the outer end of the spray bar has a nozzle connected to the vortex water chamber, the spray direction of the nozzle is parallel to the tangent direction of the outer peripheral surface of the body, and the spray direction of each nozzle is consistent along the circumference of the body, and the outer end of the spray bar is also provided with an air duct matched with the nozzle. The cooling device is energy-saving and efficient, and its circulating water atomization effect is good. The present invention also discloses a cooling tower using the above cooling device.

[0004] The heat dissipation device of some cooling towers is equipped with a spray head and a heat dissipation fan on the central axis, and heat is dissipated through the cooperation of the two. However, in actual operation, similar heat dissipation devices use a single fan for auxiliary heat dissipation, and their heat dissipation effect has an upper limit and cannot dissipate the working medium well. The low heat dissipation efficiency leads to poor practicality. Utility Model Content

[0012] Furthermore, the adjustment assembly includes a second motor, which is fixedly mounted on the side of the tower body. The shaft end of the second motor passes through the tower body and is fixedly mounted with a worm below the filling rack.

[0013] Furthermore, round rods and screw rods are fixedly installed on both sides of the bottom surface of the tower body, and are rotatably connected. The filling frame is slidably connected to the round rods and threadedly connected to the screw rods.
