Description

Technical Field

[0002] Cooling towers are used in many applications. For example, air conditioning systems for large buildings employ cooling towers to perform a portion of the heat exchange that is critical to the cooling process. Industrial processes such as chemical production, metal production, plastic production, food processing, etc. generate heat that must be handled by cooling towers. A heat exchange fluid may be circulated through the cooling tower, and at least one fan may be mounted on the cooling tower to create a cooling air flow near the heat exchange fluid. Heat is transferred from the heat exchange fluid to the air, primarily by evaporating a small portion of the fluid, which significantly reduces the temperature of the primary heat exchange fluid. The cooled heat exchange fluid may then be returned to the industrial process to perform a heat exchange function for the industrial process or commercial air conditioning system.

[0003] When the cooling tower is in use, the cooling water flows from top to bottom along the surface of the filler under the action of its own gravity. At the same time, the air intake on both sides can flow through the gaps between the fillers, thereby conducting the heat and finally being sucked away by the fan.

[0051] In one embodiment of the present invention, Figures 1 to 3 As shown, a high-efficiency heat dissipation air cooling tower is provided, comprising:

[0052] A housing 10, wherein the housing 10 is provided with an air outlet 11 extending through the top thereof, and a plurality of air inlets 12 extending through the side walls thereof, and a cooling reaction chamber 13 is formed in the hollow interior of the housing 10, wherein the air outlet 11 and all the air inlets 12 are in communication with the cooling reaction chamber 13;

[0053] The housing 10 is provided with a water inlet structure 14 connected to a hot water output end of an external device, and a water outlet structure 15 for returning water to the external device;

[0054] A fan 20, wherein the fan 20 is disposed at the air outlet 11;

[0055] A spray assembly 30, wherein the spray assembly 30 is disposed in the cooling reaction chamber 13, and the spray assembly 30 is connected to the water inlet structure 14 and sprays hot water downward;

[0056] A filler 40, wherein the filler 40 is disposed in a height direction between the spray assembly 30 and the air inlet 12, and the filler 40 is configured to be rotatable via a rotating shaft;

[0057] The outer surface of the filler 40 is provided with a plurality of main flow channels 41, and any two of the main flow channels 41 are interconnected; the filler 40 is further provided with a plurality of auxiliary flow channels 42, and any two of the auxiliary flow channels 42 are interconnected; and any two of the main flow channels 41 and the auxiliary flow channels 42 are interconnected;

[0058] as well as

[0059] The water storage tank 50 is disposed at the bottom of the housing 10 and is used to store cooled water.

[0060] Specifically, an air outlet 11 is provided on the top of the housing 10, and a plurality of air inlets 12 are evenly distributed on the side walls to ensure smooth air circulation. The interior of the housing 10 is a hollow cooling reaction chamber 13, and the air outlet 11 and the air inlet 12 are both connected to the cooling reaction chamber 13. The housing 10 is also provided with a water inlet structure 14 and a water outlet structure 15, which are respectively connected to the hot water output end and the water inlet end of the external device, forming a complete cooling cycle;

[0061] In the cooling reaction chamber 13, an efficient fan 20 is provided. The fan 20 is located at the air outlet 11. When started, it can draw outside air into the cooling reaction chamber 13 and perform heat exchange with the water in the cooling reaction chamber 13, thereby reducing the water temperature.

[0062] A spray assembly 30 is provided in the cooling reaction chamber 13, and the spray assembly 30 is connected to the water inlet structure 14. When the high-temperature hot water generated by the external equipment enters the cooling tower through the water inlet structure 14, the spray assembly 30 will spray the hot water evenly downward to form fine water droplets. In the process of falling, the water droplets are fully in contact and exchanged with the air in the cooling reaction chamber 13, thereby further reducing the water temperature;

[0063] In order to enhance the cooling effect, a filler 40 is arranged between the spray assembly 30 and the air inlet 12. This filler 40 not only has a large specific surface area, but can also be rotated by a rotating shaft. A number of main channels 41 are opened on the outer surface of the filler 40. These main channels 41 are interconnected to form a complex channel network, which is conducive to the passage of water. At the same time, a number of auxiliary channels 42 are opened inside the filler 40. They are also interconnected and connected to the main channels 41, which is conducive to the contact between water flow and wind flow.

[0065] Specifically, the fillers 40 are arranged in two groups and spaced apart in the vertical direction, which is beneficial to prolonging the falling time of the water flow and increasing the heat exchange time between the water flow and the air, thereby improving the cooling effect.

[0066] In another embodiment of the present invention, Figures 2 to 4 As shown, the two groups of fillers 40 have the same rotation speed and opposite rotation directions.

[0067] Specifically, the two groups of fillers 40 rotate at the same speed but in opposite directions. This design can further increase the turbulence of the water flow and improve the cooling effect.

[0068] In another embodiment of the present invention, Figures 2 to 4 As shown, the main flow channel 41 arranged in the same radial direction of the filler 40 is configured as two;

[0069] The two main flow channels 41 are symmetrically arranged with respect to the axial direction of the filler 40 .

[0070] The auxiliary flow channels 42 arranged along the same radial direction of the filler 40 are configured as two;

[0071] The two auxiliary flow channels 42 are symmetrically arranged with respect to the axial direction of the filler 40 .

[0072] The flow directions of all the main flow channels 41 and all the auxiliary flow channels 42 arranged in the same radial direction of the filler 40 can be aligned along the same straight line direction.

[0073] Specifically, in order to ensure the uniformity of water flow, two main flow channels 41 and two auxiliary flow channels 42 are arranged in the same radial direction of the packing 40, and the two main flow channels 41 and the auxiliary flow channels 42 are symmetrically arranged with respect to the axial direction of the packing 40. This design enables the water flow to form a symmetrical flow and exchange inside the packing 40, avoiding the phenomenon of local overheating or overcooling.

[0074] In another embodiment of the present invention, all surfaces of the filler 40 are provided with a hydrophilic coating.

[0075] Specifically, a layer of hydrophilic coating is provided on all surfaces of the filler 40. This coating can increase the contact angle and adhesion between water and the surface of the filler 40, so that water droplets can adhere more closely to the surface of the filler 40, thereby increasing the contact area and contact time between water and air. At the same time, the hydrophilic coating can also reduce the evaporation rate of water droplets and reduce water loss.

[0076] In another embodiment of the present invention, Figure 2 As shown, the spray assembly 30 includes:

[0077] A spray pipe 31, wherein the spray pipe 31 is connected to the water inlet structure 14;

[0078] A spray head 32, wherein the spray head 32 is configured in plurality, and each of the spray heads 32 is connected to the spray pipe 31;

[0079] A control valve is provided on the water inlet structure 14 .

[0080] The arrangement direction of the spray pipe 31 is parallel to the arrangement direction of the two groups of fillers 40;

[0081] Each of the spray heads 32 is disposed in the axial direction of the filler 40 , and a spraying area of ​​each of the spray heads 32 covers 1 / 3 of the surface area of ​​the filler 40 .

[0082] Specifically, the spray assembly 30 is composed of a spray pipe 31 and a plurality of spray heads 32. The spray pipe 31 is connected to the water inlet structure 14, and the spray heads 32 are evenly distributed in the axial direction of the filler 40. The spraying area of ​​each spray head 32 covers about 1 / 3 of the surface area of ​​the filler 40, so that the entire surface of the filler 40 can be evenly sprayed, and the water flow sprayed from the spray head is prevented from falling directly to the bottom of the shell 10. At the same time, we also set a control valve on the water inlet structure 14, which can adjust the flow and pressure of the spray water as needed.

[0083] In another embodiment of the present invention, a water level sensor for real-time monitoring of the water level in the water tank 50 is provided in the water tank 50 .

[0084] Specifically, a water tank 50 is provided at the bottom of the cooling tower. The water tank 50 is used to store cooled water and return the cooled water to the external device through the water outlet structure 15. In order to monitor the water level in the water tank 50 in real time, a water level sensor is provided. When the water level is too low, the sensor will send an alarm signal to remind the operator to add water in time.

[0085] The rest of this embodiment is the same as the first embodiment. The features not explained in this embodiment are all based on the explanations in the first embodiment and will not be described in detail here.
