Description

Technical Field

[0001] This utility model mainly relates to the technical field of cooling tower packing, specifically a dynamic cooling tower packing. Background Technology

[0002] A cooling tower is a heat exchange device mainly used in industrial production and refrigeration systems. It lowers the temperature of a fluid by bringing water or other working fluids into contact with air. The working principle of a cooling tower is based on the physical process of evaporative cooling. Cooling towers are very important in industrial production because they not only improve the recycling rate of water resources, but also help improve energy efficiency and reduce environmental pollution.

[0003] Cooling tower packing is the main heat exchange component of a cooling tower. It is a material inside the cooling tower used to increase the contact area between water and air and improve heat exchange efficiency. These packings usually have a porous structure, which can promote the dispersion of water droplets and prolong the residence time of water in the tower, thereby effectively transferring heat. The packings are generally in the form of blocks or sheets, fixed inside the cooling tower, and divide the water by restricting the path, further enhancing the heat exchange efficiency of the water.

[0004] Since the packing material inside the cooling tower is usually a static structure, after a period of use, the fins will experience problems such as deformation, scaling and blockage, which will affect the heat exchange efficiency. Especially in winter, when 40°C hot water passes through the packing material, the temperature of the side of the static fin that first comes into contact with the hot water (i.e., the upper side of the fin) will increase instantly, causing a temperature difference between the side of the fin that does not come into contact with the hot water (i.e., the lower side of the fin), which can easily cause deformation and damage to the packing fins.

[0005] Since the weight of the heat exchanger inside the cooling tower and the load-bearing capacity of the cooling tower are determined in advance by design and planning, metal materials cannot be used. If metal is used as the raw material, it will exceed the maximum weight limit of the heat exchanger and increase the cost by six or seven times. Utility Model Content

[0006] This utility model provides a solution that is significantly different from existing technologies, addressing the problem that existing solutions are too simplistic. Specifically, this utility model provides a dynamic cooling tower packing material to solve the technical problem in the background art where, after a period of use, the fins of the packing material in the cooling tower will deform, scale, and become clogged, affecting the heat exchange efficiency.

[0007] The technical solution adopted by this utility model to solve the above-mentioned technical problems is as follows:

[0008] This utility model provides a dynamic cooling tower packing material, comprising multiple layers of packing material disposed within the cooling tower, wherein the multiple layers of packing material are stacked in the height direction of the cooling tower.

[0009] The packing layer includes multiple heat exchange elements arranged in the horizontal direction of the cooling tower. The multiple heat exchange elements are evenly spaced and the heat exchange elements of adjacent packing layers are staggered.

[0010] The heat exchanger includes a rotating shaft and rotating fins. The rotating shaft supports the rotating fins, and the rotating fins can rotate freely around the rotating shaft.

[0011] Furthermore, the rotating fin includes a sleeve portion and a fin portion, wherein the fin portion is disposed on the outer periphery of the sleeve portion;

[0012] The rotating shaft is at least partially embedded inside the sleeve portion.

[0013] Furthermore, the sleeve portion is fitted onto the outer periphery of the rotating shaft, and the axial ends of the rotating shaft extend beyond the axial ends of the sleeve portion.

[0016] Furthermore, the number of finned portions is not limited to one;

[0017] And / or, when there are multiple fin portions, the multiple fin portions are equally spaced and arranged around the outer periphery of the sleeve portion.

[0018] A dynamic cooling tower packing includes multiple layers of packing material disposed within the cooling tower, wherein the multiple layers of packing material are stacked in the height direction of the cooling tower.

[0019] The packing layer includes multiple heat exchange elements arranged in the horizontal direction of the cooling tower. The multiple heat exchange elements are evenly spaced and the heat exchange elements of adjacent packing layers are staggered.

[0026] And / or, when there are multiple fin units, the multiple fin units are distributed at intervals along the axial direction of the rotation axis.

[0027] Furthermore, the rotating fins include, but are not limited to, elongated structures, triangular structures, arc-shaped structures, and wave-shaped structures.

[0028] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0029] This invention utilizes a central rotating shaft and rotating components to weaken the impact of water flow by rotating, thereby continuously changing the contact surface with hot water. This reduces the problem of fin deformation and damage caused by temperature differences and water pressure. Simultaneously, it promotes water droplet dispersion, prolongs the water's residence time within the tower, facilitates heat transfer, and improves heat exchange efficiency. The fins have no dead corners, making them less prone to scaling and clogging. Furthermore, since multiple fins can be installed on the sleeve section, the number of fins can be increased within a limited space to increase the contact area with water, further improving heat exchange efficiency. The structure is simple, easy to manufacture, and has low cost, making it practically valuable.

The rotating element 22 includes a sleeve portion 221 and a fin portion 222, with the fin portion 222 evenly spaced around the sleeve portion 221.

[0038] The above structure utilizes the principle of a waterwheel to reduce the impact of water flow through rotation, and continuously changes the contact surface with hot water, reducing the problem of fin deformation and damage caused by temperature difference and water pressure. At the same time, it promotes water droplet dispersion, prolongs the residence time of water in the tower, facilitates heat transfer, and improves heat exchange efficiency.
