Description

Technical Field

[0001] This utility model belongs to the technical field of industrial cooling equipment, specifically relating to a skid-mounted counter-flow closed cooling tower. Background Technology

[0002] In the field of industrial cooling, closed-circuit cooling towers are widely used due to their water-saving and environmentally friendly characteristics. However, in industrial scenarios with smaller cooling capacity, such as small machining equipment and precision electronic cooling systems, the coolant in traditional closed-circuit cooling towers enters directly from the inlet of the cooling coil and flows directly out from the outlet after passing through the coil. This requires additional equipment such as circulating pumps and buffer water tanks. Moreover, the components are installed separately, which leads to complex on-site piping and extended construction period. This is especially difficult to adapt to places with narrow spaces or where it is inconvenient to excavate water tanks. It not only increases the difficulty of excavating water tanks and connecting pipes on-site, but also extends the installation period. When the equipment needs maintenance, the traditional single-pipe system must be shut down for repair, which seriously affects the continuity of production. Utility Model Content

[0023] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0024] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.

[0025] Example 1

[0026] Reference Figure 1-6 This is the first embodiment of the present invention, which provides a skid-mounted counter-flow closed-loop cooling tower, comprising:

[0027] The main structure 100 includes a base frame 101 and a cooling assembly 102 disposed on the top of the base frame 101;

[0028] The circulation mechanism 200 includes a water tank assembly 201 disposed on the top of the bottom frame 101 and a conveying assembly 202 disposed on one side of the water tank assembly 201. The water tank assembly 201 is used to collect and temporarily store the returned cooling water, and the conveying assembly 202 is used to convey the cooling water in the water tank assembly 201 to the cooling assembly 102 for cooling.

[0029] It should be noted that the bottom frame 101 is made of welded steel structure, which facilitates overall handling.

[0030] Specifically, the cooling assembly 102 includes a cooling tower 102a disposed on the top of the bottom frame 101, a cooling coil inlet 102b disposed on one side of the cooling tower 102a, a cooling plate 102c disposed on the cooling tower 102a, and a cooling coil outlet 102d disposed on one side of the cooling coil inlet 102b.

[0031] It should be noted that the cooling tower 102a is vertically installed on the top of the base frame 101 and adopts a counter-flow design. It is equipped with an axial flow fan and a spray system. The coolant to be cooled flows in the closed cooling plate 102c. The heat is transferred to the outer surface of the tube through the coil wall. The spray system sprays water evenly onto the outer wall of the coil to form a water film. At the same time, the axial flow fan drives the air to flow counter-currently from bottom to top to contact the coil, carrying away the latent heat of vaporization of the spray water, thereby reducing the temperature of the coolant.

[0032] Furthermore, the water tank assembly 201 includes a mounting bracket 201a disposed on the top of the bottom frame 101, a water tank 201b mounted on the top of the mounting bracket 201a, a water tank inlet 201c disposed on one side of the water tank 201b, and a float valve 201d disposed on the top of one side of the water tank 201b.

[0033] It should be noted that the mounting bracket 201a is welded to one end of the bottom frame 101 and is used to install the water tank 201b. The water tank 201b is used to temporarily store coolant, and the float valve 201d is used to replenish water into the water tank 201b to maintain a constant water level.

[0034] Furthermore, the conveying assembly 202 includes two first conveying pipes 202a symmetrically arranged at the bottom of the water tank 201b, a first butterfly valve 202b arranged on the first conveying pipes 202a, and a circulating water pump 202c arranged at one end of the first conveying pipes 202a.

[0035] It should be noted that the bottom of the water tank 201b has two water outlets, which are connected to the two first delivery pipes 202a respectively.

[0036] Preferably, the conveying assembly 202 further includes a second conveying pipe 202d disposed at the output end of the circulating water pump 202c, a second butterfly valve 202e disposed on the second conveying pipe 202d, and a three-way conveying pipe 202f disposed at one end of the second conveying pipe 202d.

[0037] It should be noted that the circulating water pump 202c draws coolant from the water tank 201b through the first delivery pipe 202a, and then delivers it to the cooling plate 102c for cooling through the second delivery pipe 202d.

[0038] The three-way delivery pipe 202f is connected to the ends of the two second delivery pipes 202d and the cooling coil inlet 102b, respectively.

[0039] It should be noted that the first delivery pipe 202a, the first butterfly valve 202b, the circulating water pump 202c, the second delivery pipe 202d, and the second butterfly valve 202e are all symmetrically arranged in two sets, which are connected to the three-way delivery pipe 202f through two second delivery pipes 202d respectively. One set is a spare and can be flexibly switched during use, which facilitates equipment maintenance and repair after damage.

[0040] Specifically, the cooling coil outlet 102d is connected to the input end of the equipment to be cooled, and the water tank inlet 201c is connected to the output end of the equipment to be cooled.

[0041] It should be noted that after the coolant is cooled by the cooling component 102, it flows into the equipment to be cooled from the outlet 102d of the cooling coil and cools the equipment. After absorbing heat, the coolant flows back into the water tank 201b through the water tank inlet 201c.

[0042] In use, the entire device is first moved to the required location for installation via the forklift slot at the bottom of the base frame 101. During operation, coolant is first added to the water tank 201b via the float valve 201d. Then, one of the circulating water pumps 202c is started, and the corresponding first butterfly valve 202b and second butterfly valve 202e are opened. The other set of first butterfly valves 202b and second butterfly valves 202e is closed. At this time, the circulating water pump 202c draws the coolant from the water tank 201b through its bottom outlet and delivers it to the three-way conveying pipe 2 via the first conveying pipe 202a and the second conveying pipe 202d. 02f, and then enter the cooling plate 102c inside the cooling tower 102a through the cooling coil inlet 102b. The spray system on the cooling tower 102a sprays water evenly onto the outer wall of the cooling plate 102c to form a water film. The axial flow fan drives the air to flow counter-currently from bottom to top to contact the coil, carrying away the latent heat of vaporization of the spray water and achieving cooling of the coolant. The cooled coolant flows from the cooling coil outlet 102d into the equipment to be cooled to cool it down. The cooled coolant after absorbing heat flows back to the water tank 201b through the water tank inlet 201c for reuse. At the same time, the float valve 201d replenishes the coolant in a timely manner to maintain a constant water level in the water tank.

[0043] If one of the delivery pipelines requires maintenance, the corresponding first butterfly valve 202b, second butterfly valve 202e, and circulating water pump 202c can be closed, and the system can be switched to another pipeline to ensure continuous operation of the equipment.

[0044] In summary, the main structure 100, through the skid-mounted design of the steel structure base frame 101, enables rapid transport and stable installation of the device, greatly shortening on-site construction time. It also minimizes the overall site footprint and facilitates pipework. The circulation mechanism 200 achieves stable liquid level through the float valve 201d of the water tank assembly 201, while the conveying assembly 202 enables efficient circulation and delivery of the coolant. The two symmetrically arranged sets of conveying pipelines can be flexibly switched to ensure continuous operation during maintenance. Furthermore, the cooling coil outlet 102d is connected in a closed loop to the equipment to be cooled, and together with the coolant return flow from the water tank 201b, forms a highly efficient and energy-saving closed-loop cooling circulation system. The overall structure is compact, operates stably, and is easy to maintain.
