Description

Technical Field

[0001] This utility model relates to the field of reactors, specifically a water-cooled reactor. Background Technology

[0002] Water-cooled reactors are high-efficiency heat dissipation electrical devices that use water cooling. They are mainly used in scenarios such as limiting short-circuit current, reactive power compensation, or filtering.

[0003] When the reactor is running, the coil generates Joule heat as current flows through it. The water-cooled reactor removes the heat by circulating cooling water. The cooling water circulates under the drive of a water pump, carrying the heat to an external radiator, and finally releasing it into the environment through air or another cooling water path.

[0004] In existing water-cooled reactors, cooling water pipes are typically placed between the iron core and the windings during cooling. The spiral arrangement of the pipes is used to dissipate heat from the iron core. However, during use and observation, it has been found that the coolant gradually heats up during the heat exchange process due to heat absorption. This results in insufficient contact time between the coolant and the heat in the later stages of the circuit, thus reducing the heat dissipation effect.

[0005] Therefore, a water-cooled reactor is proposed to address the above problems. Utility Model Content

[0006] In order to overcome the shortcomings of the prior art, at least one technical problem raised in the background art is solved.

[0007] The technical solution adopted by this utility model to solve its technical problem is as follows: A water-cooled reactor of this utility model includes a housing, on the top of which a winding and an iron core are fixedly installed in sequence; the winding is sleeved on the outside of the iron core; a water distributor is fixedly installed on one side of the housing; the top of the water distributor is provided with an inlet pipe and an outlet pipe; a cooling pipe is provided on the outside of the iron core, the cooling pipe includes an upper half and a lower half, and the lower half of the cooling pipe is densely arranged; the end of the cooling pipe is fixedly connected to the water distributor; the inlet pipe, the outlet pipe, and the cooling pipe are connected; through the two cooling pipes with different spacing, the heat exchange time between the cooling liquid and the iron core can be adjusted according to the temperature of the cooling liquid in different sections, thereby improving the cooling effect of the device on the iron core.

[0008] Preferably, a plurality of heat-conducting plates are fixedly connected to the outer wall of the iron core; the surface of the heat-conducting plates is arc-shaped and the heat-conducting plates are evenly distributed on the outer side of the iron core; the cooling pipes are connected through the heat-conducting plates; by setting the heat-conducting plates, the heat-conducting plates can increase the contact area between the heat on the iron core and the cooling pipes, thereby enabling forced cooling of the iron core.

[0009] Preferably, the heat-conducting plate stores oil inside, and the oil volume inside the heat-conducting plate is set to be nearly full; multiple protruding plates are fixed to the inner wall of the heat-conducting plate; by setting the heat-conducting plate as a hollow structure and filling the cavity with nearly full oil, the oil can evenly absorb the heat on the heat-conducting plate, reducing the uneven heat distribution on the heat-conducting plate. When the oil-dispersing device is working, it will generate vibration, which can agitate the oil inside the heat-conducting plate. Since the oil is set to be nearly full, it can collide with the protruding plates when flowing, enhancing the turbulence effect of the oil inside the heat-conducting plate, thereby improving the uniformity of temperature distribution in the oil.

[0010] Preferably, thermal grease is provided between the heat-conducting plate and the iron core; by providing thermal grease, the thermal conductivity between the heat-conducting plate and the iron core can be improved, thereby enhancing the heat dissipation effect of the device on the iron core.

[0011] Preferably, a filter is installed at the top of the inlet pipe; the inner wall of the filter is provided with a filter element; by setting the filter element, the coolant can pass through the filter element and be filtered and impurities removed before entering the inside of the inlet pipe, so as to reduce the impurities that may be carried in the coolant and ensure the stable flow of the coolant in the cooling pipe.

[0012] Preferably, a throat is provided between the filter and the inlet pipe; by providing a throat, since the pressure inside the filter remains constant, the flow cross section at the throat is reduced, thus accelerating the delivery of coolant and increasing the frequency of coolant circulation.

[0013] The advantages of this utility model are:

[0014] 1. The water-cooled reactor of this utility model uses two cooling pipes with different spacings to adjust the heat exchange time between the cooling liquid and the iron core according to the temperature of the cooling liquid in different sections, thereby improving the cooling effect of the device on the iron core.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0024] Specific implementation examples are given below.

[0025] Please see Figures 1 to 5As shown in the embodiment of this utility model, a water-cooled reactor includes a housing 1. A winding 12 and an iron core 13 are sequentially fixedly mounted on the top of the housing 1. The winding 12 is sleeved around the iron core 13. A water distributor 14 is fixedly mounted on one side of the housing 1. The top of the water distributor 14 has an inlet pipe 15 and an outlet pipe 16. A cooling pipe 17 is provided outside the iron core 13. The cooling pipe 17 includes an upper half and a lower half, with the lower half being densely arranged. The end of the cooling pipe 17 is fixedly connected to the water distributor 14. The inlet pipe 15, the outlet pipe 16, and the cooling pipe 17 are interconnected. When the iron core 13 is working, it generates heat. At this time, coolant can be pumped from the outside into the inlet pipe 15. The coolant can enter the cooling pipe 17 through the inlet pipe 15 and conduct heat to the iron core 13. The heat accumulated on the surface of core 13 is absorbed to dissipate heat from the iron core 13. During the process, the coolant temperature in the upper half of the cooling pipe 17 is low, and the required heat dissipation effect can be achieved through a shorter heat exchange time. The coolant temperature in the lower half of the cooling pipe 17 is higher, so the heat exchange time between the coolant and the surface of the iron core 13 can be increased by densifying the cooling pipes. Finally, the coolant that has completed heat exchange can be discharged from the outlet pipe 16 through the cooling pipe 17 into the cooling mechanism. After cooling, it is then circulated and pumped back to the inlet pipe 15. It is worth mentioning that the specific number of cooling pipes 17 in the figure is only for illustration. In actual production, it can be flexibly adjusted according to the size of the iron core 13. By setting two sections of cooling pipes 17 with different spacing, the heat exchange time between the coolant and the iron core 13 can be adjusted according to the temperature of the coolant in different sections, thereby improving the cooling effect of the device on the iron core 13.

[0026] Please see Figure 3 and Figure 4 As shown, multiple heat-conducting plates 2 are fixed to the outer wall of the iron core 13; the surface of the heat-conducting plates 2 is arc-shaped, and the heat-conducting plates 2 are evenly distributed on the outside of the iron core 13; the cooling pipe 17 is through the heat-conducting plates 2; the heat on the surface of the iron core 13 can be transferred to the heat-conducting plates 2, and can penetrate the interior of the heat-conducting plates 2 through the cooling pipe 17, so that the coolant in the cooling pipe 17 can force the heat transferred inside the heat-conducting plates 2 to cool, thereby improving the cooling effect of the device on the iron core 13; by setting the heat-conducting plates 2, the heat-conducting plates 2 can increase the contact area between the heat on the iron core 13 and the cooling pipe 17, thereby enabling forced cooling of the iron core 13.

[0027] Please see Figure 4As shown, the heat-conducting plate 2 stores oil inside, and the oil volume inside the heat-conducting plate 2 is set to be almost full; multiple protruding plates 3 are fixed to the inner wall of the heat-conducting plate 2; by setting the heat-conducting plate 2 as a hollow structure and filling the cavity with almost full oil, the oil can evenly absorb the heat on the heat-conducting plate 2, reducing the uneven heat distribution on the heat-conducting plate 2. When the oil-dispersing device is working, it will generate vibration, which can agitate the oil inside the heat-conducting plate 2. Since the oil is set to be almost full, it can collide with the protruding plates 3 when flowing, enhancing the turbulence effect of the oil inside the heat-conducting plate 2, thereby improving the uniformity of temperature distribution in the oil.

[0028] Please see Figure 3 and Figure 4 As shown, thermal grease 4 is provided between the heat-conducting plate 2 and the iron core 13; by providing thermal grease 4, the thermal grease 4 can improve the heat conduction between the heat-conducting plate 2 and the iron core 13, thereby enhancing the heat dissipation effect of the device on the iron core 13.

[0029] Please see Figure 5 As shown, a filter 5 is installed at the top of the inlet pipe 15; the inner wall of the filter 5 is provided with a filter element 52; by setting the filter element 52, the coolant can pass through the filter element 52 and be filtered and removed before entering the inlet pipe 15, so as to reduce the impurities that may be carried in the coolant and ensure the stable flow of the coolant in the cooling pipe 17.

[0030] Please see Figure 5 As shown, a throat 6 is provided between the filter 5 and the inlet pipe 15. By providing the throat 6, since the pressure inside the filter 5 remains constant, the flow cross section at the throat 6 is reduced, which can accelerate the delivery of coolant and increase the frequency of coolant circulation.

[0031] Working principle: When the iron core 13 is working, it generates heat. At this time, coolant can be pumped into the inlet pipe 15 from the outside. The coolant can enter the cooling pipe 17 through the inlet pipe 15 and absorb the heat accumulated on the surface of the iron core 13 through heat conduction, thereby dissipating heat from the iron core 13. During the process, the coolant temperature in the upper half of the cooling pipe 17 is low, and the required heat dissipation effect can be achieved in a shorter heat exchange time. The coolant temperature in the lower half of the cooling pipe 17 is higher, so the contact area between the coolant and the surface of the iron core 13 can be increased by denser arrangement. The heat exchange time is short. After heat exchange, the coolant, having completed its exchange, can be discharged from the outlet pipe 16 through the cooling pipe 17 into the cooling mechanism. After cooling, it is then circulated back to the inlet pipe 15. It is worth noting that the specific number of cooling pipes 17 shown in the diagram is for illustrative purposes only; in actual production, it can be flexibly adjusted according to the size of the iron core 13. Heat from the surface of the iron core 13 can be transferred to the heat-conducting plate 2. The coolant can penetrate the interior of the heat-conducting plate 2 through the cooling pipes 17, forcibly cooling the heat transferred inside the heat-conducting plate 2, thus improving the efficiency of the device. The cooling effect on the iron core 13: By setting the heat-conducting plate 2 as a hollow structure and filling the cavity with nearly full oil, the oil can evenly absorb the heat on the heat-conducting plate 2, reducing uneven heat distribution on the heat-conducting plate 2. The oil can disperse the vibration generated during operation, which can agitate the oil in the heat-conducting plate 2. Since the oil is nearly full, it can collide with the convex plate 3 during flow, enhancing the turbulence effect of the oil in the heat-conducting plate 2, thereby improving the uniformity of temperature distribution in the oil. By setting the heat-conducting plate 13 as a hollow structure, the cooling effect on the iron core 13 is improved. The thermal grease 4 can improve the heat conduction between the heat-conducting plate 2 and the iron core 13, thereby enhancing the heat dissipation effect of the device on the iron core 13. By setting the filter element 52, the coolant can pass through the filter element 52 and be filtered and impurities removed before entering the inlet pipe 15, so as to reduce the impurities that may be carried in the coolant and ensure the stable flow of the coolant in the cooling pipe 17. By setting the throat 6, since the pressure inside the filter 5 remains unchanged, the flow cross section at the throat 6 is reduced, so the delivery of coolant can be accelerated and the frequency of coolant circulation can be increased.

[0032] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
