Description

Technical Field

[0001] The utility model relates to the technical field of cooling water circulating towers, in particular to a closed cooling coil and a cooling water circulating tower. Background Technique

[0002] Cooling water circulating towers are indispensable cooling equipment in industrial production and large buildings. Its main function is to achieve heat exchange through the flow of circulating water and contact with air, so as to reduce the water temperature and ensure the normal operation and efficiency of equipment and buildings. At present, most chemical plants on the market use open cooling circulating water towers, which have problems such as easy scaling of system pipes and cooled equipment exposed to the outside, and easy pollution of the cooled medium directly contacting the air, resulting in damage to associated equipment and high operating costs of the system. Based on this, the utility model proposes a closed cooling coil and a cooling water circulating tower, which intends to adopt a closed-loop design to strictly control the water quality during use, effectively avoiding problems such as long-term odor emission of open cooling water towers, easy scaling of system pipes and cooling equipment.

[0003] According to the search, the Chinese patent document, publication number: CN209165891U, discloses a closed cooling water circulation device. The cooling water is sent into the chiller by the pressure of the closed-loop cooling water pump. After taking away the heat of the chiller, such as heat exchangers, condensers, reactors, etc., the temperature rises, and then it is sent to the closed cooling tower for spraying. Due to the rotation of the fan of the closed cooling tower, during the spraying and falling process of the cooling water, it continuously undergoes heat and moisture exchange with the outdoor air and cools down. The cooled water falls into the condensate storage tank, and then is pressurized again by the closed-loop cooling water pump and enters the next cycle. However, in the actual use process of this device, the cooling water still exchanges heat with the outdoor air to cool down. Therefore, not only does it not achieve an effective closed effect, but also the cooling water will be polluted after long-term use, thus damaging related equipment and reducing the overall practicability and service life of the device.

[0006] (II) Technical Solutions

[0007] To achieve the above object, the present utility model provides the following technical solutions: A closed cooling coil, including side supports, wherein the inner side surfaces of the side supports are fixedly installed with upper cooling pipes and lower cooling pipes, the outer side surface of the upper cooling pipe is fixedly installed with a first connecting pipe and a coil body, the outer side surface of the first connecting pipe is fixedly installed with a second connecting pipe, and the outer side surface of the coil body is fixedly installed with heat dissipation fins and stabilizing rods.

[0008] A cooling water circulation tower, including a first box body and a closed cooling coil, wherein a heat exchanger is fixedly installed inside the first box body, an end cover is fixedly installed on the end surface of the heat exchanger, a heat exchange pipe is fixedly installed inside the heat exchanger, heat exchange fins are fixedly installed on the outer side surface of the heat exchange pipe, an inlet and an outlet are fixedly installed on the outer side surface of the heat exchanger, a third connecting pipe is fixedly installed on the bottom surface of the outlet, one end of the third connecting pipe away from the outlet is fixedly connected to a high-pressure water pump, a second box body is fixedly installed on the top surface of the first box body, and a negative pressure fan is fixedly installed on the top surface of the second box body.

[0009] Preferably, the number of the end covers is set to two, and a water inlet pipe and a water outlet pipe are respectively connected to the outer side surfaces of the two end covers.

[0010] Through the above technical solutions, external heat medium can be sent into the inside of the end cover through the water inlet pipe. After that, when the heat medium flows through the inside of the heat exchange pipe, it can exchange heat with the cooling liquid in the heat exchanger. Then, the cooled medium can flow into the inside of the end cover near the right side, and then can flow out from the water outlet pipe. It can not only effectively exchange heat and cool the heat source, but also avoid the mixing of different media, improving the overall practicability and working efficiency of the device.

[0011] Preferably, the number of the heat exchange pipes and the heat exchange fins are both set to be multiple, and the multiple heat exchange fins are evenly distributed on the outer side surfaces of the multiple heat exchange pipes.

[0012] Through the above technical solutions, when the external heat medium flows through the inside of the multiple heat exchange pipes, the multiple heat exchange fins can effectively increase the contact area with the cooling liquid in the heat exchanger, so as to exchange heat and cool more efficiently, improving the overall cooling efficiency of the device.

[0013] Preferably, the number of the side supports, the upper cooling pipes and the lower cooling pipes are all set to two, and the two side supports are fixedly installed inside the second box body.

[0014] Through the above technical solutions, the two side supports can increase the overall stability of the structure, while the two upper cooling pipes and lower cooling pipes can increase the flow efficiency of the cooling liquid, improving the overall practicability of the device.

[0015] Preferably, the number of the first connecting pipes and the second connecting pipes is both set to two. The two first connecting pipes are respectively connected to the outer side surfaces of the upper cooling pipe and the lower cooling pipe, and one end of the other second connecting pipe far away from the first connecting pipe is fixedly connected to the outer side surface of the high-pressure water pump, and one end of the other second connecting pipe far away from the first connecting pipe is fixedly connected to the top surface of the water inlet.

The high-pressure water pump can send the coolant into the interior of the upper cooling pipe through one of the second connecting pipes and the first connecting pipe. Then, the coolant flowing through the interior of the coil body can exchange heat with the external air. After the coolant is cooled, it can flow into the interior of the water inlet through the lower cooling pipe, the other first connecting pipe, and the second connecting pipe in sequence. Therefore, the external heat medium can be effectively circulated and cooled, improving the overall practicality of the device.

Thus, the coolant can be cooled more efficiently. At the same time, the multiple coil bodies can also play a good sealing role, preventing the coolant from directly contacting the outside world, effectively ensuring the water quality, ensuring the normal operation of the device, and increasing the overall service life.

[0019] Preferably, the number of the stabilizing rods is set to be multiple, and the multiple stabilizing rods are connected to the inner side surfaces of the two side supports.

[0022] Through the above technical solution, when the negative pressure fan is started, the negative pressure fan can suck the external air from the multiple ventilation holes into the interior of the second box body and discharge it from here. Therefore, the flow rate of the air inside the second box body can be effectively increased, and thus the heat in the air can be taken away more quickly, improving the overall cooling efficiency of the device.

Then the cooled medium can flow into the inside of the end cover near the right side, and then can flow out from the water outlet pipe. It can not only effectively exchange heat and cool the heat source, but also avoid the mixing of different media, improving the overall practicability and working efficiency of the device.

[0025] 2. By starting the high-pressure water pump, the high-pressure water pump can send the coolant into the inside of the upper cooling pipe through one of the second connecting pipes and the first connecting pipe.

At the same time, the multiple coil bodies can also play a good sealing effect, preventing the coolant from directly contacting the outside world, effectively ensuring the water quality, ensuring the normal operation of the device, and improving the overall service life. After the coolant is cooled, it can flow into the inside of the water inlet through the lower cooling pipe and the other first connecting pipe and second connecting pipe in turn. Therefore, it can effectively circulate and cool the external heat medium, improving the overall practicability of the device. At the same time, by starting the negative pressure fan, the negative pressure fan can suck the external air from the multiple ventilation holes into the inside of the second box body and discharge it from here. Therefore, it can effectively increase the flow rate of the air inside the second box body, so as to take away the heat in the air more quickly, improving the overall cooling efficiency of the device.
