Description

Technical Field

[0001] This utility model relates to the field of cooling equipment technology, specifically a cooling tower device. Background Technology

[0002] Medium-frequency induction furnaces (IF furnaces) generate heat under high-current conditions, causing a temperature rise. Components carrying high current, such as the furnace coils, magnetic yoke, water-cooled cables, and power cabinets, all require cooling. Cooling towers are common cooling devices in IF furnace water-cooling systems. A cooling tower uses water as a circulating coolant to absorb heat from the system and release it into the atmosphere, thus lowering the water temperature. In existing technology, cooling towers contain heat exchangers, which include continuously arranged U-shaped pipes. The medium to be cooled is contained within these pipes. Cold air entering the cooling tower from the outside and cooling water sprayed onto the heat exchanger simultaneously cool the medium within the pipes. However, the direct spraying of cooling water onto the heat exchanger results in a relatively small contact area, meaning the sprayed cooling water does not fully contact the medium inside the pipes, thus affecting the cooling tower's cooling efficiency. Utility Model Content

[0003] The purpose of this invention is to provide a cooling tower device with better cooling effect to overcome the problems existing in the existing equipment.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a cooling tower device, including a casing, a fan and a water pump installed on the casing, a dispersing mechanism, a sprayer, a heat exchanger, a packing layer, and a water collection tank arranged sequentially from top to bottom inside the casing. The fan includes fan blades installed on the top of the casing and a rotating shaft connected to the fan blades. The sprayer includes a spray plate and a spray pipe connected to the spray plate. The spray plate is located above the spray pipe, and multiple nozzles are provided on the upper surface of the spray plate. The water pump is connected between the spray pipe and the water collection tank. The dispersing mechanism includes a first mesh cover and a second mesh cover. The first mesh cover is located above the spray plate, and the second mesh cover is located directly above the first mesh cover and connected to the rotating shaft of the fan.

[0005] Based on the above technical solution, the present invention can be further improved as follows:

[0006] As a further improvement to the above technical solution, two fans are provided on the top of the casing. Each fan also includes a fan frame and a motor installed at the center of the top of the fan frame. The fan blades are located inside the fan frame. A fixing plate and a protective net are provided on the top of the fan frame. The motor is fixed to the center of the fixing plate with screws. The fixing plate has multiple air outlets around the motor. The protective net is located at the air outlet. The rotating shaft is arranged vertically. The upper end of the rotating shaft is connected to the output shaft of the motor. Two dispersing mechanisms are provided. The inner side of the first net is connected and fixed to the spray plate through a connecting rod. The second net is connected to the lower end of the rotating shaft.

[0007] As a further improvement to the above technical solution, the spray plate is circular and there are two of them. The spray pipe extends horizontally, the two spray plates are located above the spray pipe, and the spray pipe is provided with two branch pipes. The two spray plates are connected to the spray pipe through the branch pipes, and the water collection tank is connected to the refrigeration equipment through a pipe.

[0008] As a further improvement to the above technical solution, the housing is provided with a partition above the water collection tank, the partition has multiple through holes, and a filler layer is provided on the partition. The filler layer is a honeycomb filler layer made of PVC or wood.

[0009] As a further improvement to the above technical solution, the casing is provided with an inlet pipe and an outlet pipe, and the heat exchanger is provided with an inlet and an outlet.

The air inlet is located on the left side plate and the right side plate. The water pump is installed on the base by screws.

[0012] The beneficial effects of this invention are as follows: The cooling tower device of this invention disperses the cooling water sprayed from the sprayer through a dispersing mechanism, allowing the sprayed cooling water to diffuse across different parts of the heat exchanger, ensuring full contact with the medium to be cooled within the heat exchanger. This increases the thermal contact area and guarantees the cooling effect of the cooling tower device.

[0025] like Figures 1 to 7 As shown, a preferred embodiment of the present invention provides a cooling tower device, including a casing 1, a fan 2 and a water pump 8 installed on the casing 1, a dispersing mechanism 3, a sprayer 4, a heat exchanger 5, a packing layer 6 and a water collection tank 7 arranged sequentially from top to bottom on the inner side of the casing 1.

[0026] Two fans 2 are provided on the top of the casing 1. Each fan 2 includes a fan frame 21, a motor 24 installed at the center of the top of the fan frame 21, a fan blade 22 located inside the fan frame 21, and a rotating shaft 23 connected to the motor 24 and the fan blade 22. The top of the fan frame 21 is provided with a fixing plate 211 and a protective net 212. The motor 24 is fixed to the center of the fixing plate 211 by screws. The fixing plate 211 has multiple air outlets around the motor 24. The air outlets are used to discharge water vapor inside the casing 1. The protective net 212 covers the air outlets. The rotating shaft 23 is arranged vertically, and the upper end of the rotating shaft 23 is connected to the output shaft of the motor 24.

[0027] The sprayer 4 includes two circular spray discs 41 and a spray pipe 42 connected to the spray discs 41. The spray pipe 42 extends horizontally, and the two spray discs 41 are located above the spray pipe 42. The upper surface of the spray discs 41 is provided with multiple nozzles 411. The spray pipe 42 is provided with two branch pipes 421, and the two spray discs 41 and the spray pipe 42 are connected through the branch pipes 421.

[0028] Water pump 8 is connected to spray pipe 42 via outlet pipe 82, and inlet pipe 81 connects water pump 8 to water collection tank 7. Water collection tank 7 is located at the bottom inside the casing 1 and is connected to refrigeration equipment via pipes for cooling the water in water collection tank 7. When water pump 8 is working, it draws the cooling water in water collection tank 7 along inlet pipe 81 and outlet pipe 82 to spray plate 41, causing the water to spray upward from multiple nozzles 411 of spray plate 41.

[0029] The housing 1 has a partition 14 above the water collection tank 7. The partition 14 has multiple through holes. The packing layer 6 is placed on the partition 14. The packing layer 6 is a honeycomb packing layer made of PVC or wood. Heat exchange is achieved by increasing the contact area between the water film and the air. The water flows on the surface of the packing layer 6 to form a thin film and exchange heat with the air.

[0030] Two dispersing mechanisms 3 are provided. Each dispersing mechanism 3 includes a first mesh cover 31 and a second mesh cover 32. The first mesh cover 31 is placed above the spray plate 41. The inner side of the first mesh cover 31 is connected and fixed to the spray plate 41 through a connecting rod 311. The first mesh cover 31 can divide and disperse the water sprayed from the nozzle 411 of the spray plate 41. The second mesh cover 32 is placed directly above the first mesh cover 31 and is connected to the lower end of the rotating shaft 23 of the fan 2. The rotating shaft 23 is driven to rotate by the motor 24, which in turn drives the second mesh cover 32 to rotate. The rotating second mesh cover 32 can further disperse the small water droplets divided by the first mesh cover 31. Thus, by using the first mesh cover 31 and the second mesh cover 32 together, the water sprayed from the nozzle 411 of the spray plate 41 can be fully dispersed and diffused to different parts of the heat exchanger 5, so that the dispersed water can fully contact the medium to be cooled in the heat exchanger 5, thereby increasing the heat contact area.

[0031] The casing 1 is equipped with an inlet pipe 11 and an outlet pipe 12. The heat exchanger 5 is equipped with an inlet and an outlet. The inlet pipe 11 is connected to the inlet of the heat exchanger 5, and the outlet pipe 12 is connected to the outlet of the heat exchanger 5. The medium to be cooled (hot water) flows into the heat exchanger 5 from the inlet pipe 11, and flows out from the outlet pipe 12 after being cooled. Rectangular air inlets 13 are provided on both sides of the casing 1. External cold air enters the casing 1 along the air inlets 13. Multiple long strip-shaped guide plates are detachably installed at the air inlets 13. The medium to be cooled in the heat exchanger 5 is cooled simultaneously by the cold air entering the cooling tower device from the outside and the cooling water sprayed on the heat exchanger 5.

[0032] Specifically, the housing 1 includes a base 101, a top plate 102, and a front side plate 103, a rear side plate 104, a left side plate 105, and a right side plate 106 connected between the base 101 and the top plate 102. The water inlet pipe 11, the water outlet pipe 12, the water inlet pipe 81, and the water outlet pipe 82 are disposed through the front side plate 103. The top plate 102 has two through holes. The fan frame 21 is disposed at the through holes of the top plate 102. The air inlet 13 is disposed on the left side plate 105 and the right side plate 106. The water pump 8 is mounted on the base 101 by screws.

[0033] When this utility model is in use, the fan 2 operates, and external cold air enters from the air inlet 13 of the casing 1, cooling the medium to be cooled inside the heat exchanger 5. When the water pump 8 operates, it draws the cooling water in the water collection tank 7 along the water inlet pipe 81 and the water outlet pipe 82 to the spray plate 41, so that the water is sprayed upward from multiple nozzles 411 of the spray plate 41. The first screen 31 above the spray plate 41 divides and disperses the water sprayed from the nozzles 411 of the spray plate 41 into small water droplets. At the same time as the fan 2 operates, the rotating shaft 23 drives the second screen 32 to rotate. The rotating second screen 32 further disperses the small water droplets divided by the first screen 31. The dispersed water diffuses to different parts of the heat exchanger 5, so that the dispersed water comes into full contact with the medium to be cooled inside the heat exchanger 5, increasing the heat contact area and improving the cooling effect of the cooling tower device. After exchanging heat with heat exchanger 5, the cooling water falls into packing layer 6 and water collection tank 7. The water flows onto the surface of packing layer 6 to form a thin film and exchange heat with the air. Finally, it is collected by water collection tank 7 to realize the recycling of cooling water.

[0034] The cooling tower device of this utility model disperses the cooling water sprayed from the sprayer 4 by setting a dispersing mechanism 3, so that the sprayed cooling water is diffused in different parts of the heat exchanger 5 and fully contacts the medium to be cooled in the heat exchanger 5, increasing the heat contact area and ensuring the cooling effect of the cooling tower device. After spraying, the cooling water falls into the water collection tank 7 after passing through the heat exchanger 5, realizing the reuse of cooling water in the cooling tower device.

[0035] Any descriptions not covered in the above specific embodiments of this utility model belong to the well-known technology in the field, and can be implemented by referring to the well-known technology.

[0036] Based on the preferred embodiments of this utility model described above, those skilled in the art can make various changes and modifications without departing from the technical concept of this utility model. The technical scope of this utility model is not limited to the contents of the specification, but must be determined according to the scope of the claims.
