[0002] In modern power systems, phase regulators, as key devices for reactive power compensation, play a vital role in maintaining stable grid operation and improving transmission capacity. Phase regulators generate significant heat during operation, so the performance of their cooling systems is directly related to their operating efficiency and lifespan. Currently, cooling technologies for phase regulators primarily include air cooling and water cooling systems.

[0003] For the air cooling system, it can directly introduce external air into the phase regulator cooling system. However, the disadvantages of this system are also obvious. Dust and pollutants in the external air can easily enter the phase regulator, causing dust accumulation in the internal components. This will not only reduce the cooling efficiency, but may also cause the internal circuit of the phase regulator to short-circuit or mechanical failure, affecting its long-term stable operation. To overcome this problem, current attempts are being made to exchange heat between the external air and the internal air of the phase regulator to achieve a cooling effect. However, the structure of such equipment is complicated and the cost is high. In addition, the energy consumption and maintenance costs of such systems are relatively high. Therefore, existing companies rarely choose them.

[0004] For the water cooling system, its cooling effect is limited by the number and efficiency of heat exchange.

DETAILED DESCRIPTION

[0023] The present invention will be further described below with reference to the accompanying drawings and specific embodiments so that those skilled in the art can better understand the present invention and implement it. However, the embodiments are not intended to limit the present invention. Example 1

[0024] See also Figure 1As shown, this embodiment provides a phase condenser cooling system, which includes: a circulation mechanism 100, the circulation mechanism 100 includes a circulation fan 110 and a circulation duct 120, the circulation fan 110 is connected to the phase condenser 600 to be cooled, and the circulation fan 110, the circulation duct 120 and the phase condenser 600 to be cooled are interconnected to realize the circulation of the internal gas of the phase condenser 600 to be cooled; an air cooling mechanism 200, the air cooling mechanism 200 includes a cooling fan 210 and a cooling duct 120. The air duct 220, both ends of the cooling air duct 220 are connected to the outside world, the cooling fan 210 is arranged inside the cooling air duct 220, at least part of the circulating air duct 120 and at least part of the outer surface of the cooling air duct 220 are in contact with each other for heat exchange; the water cooling mechanism 300, the water cooling mechanism 300 includes a water supply component 310 and at least one spray head 320, the spray head 320 is connected to the water supply component 310, and is oriented towards the contact point between the circulating air duct 120 and the cooling air duct 220.

[0025] The condenser cooling system described in this embodiment combines air and water cooling processes, significantly improving the cooling efficiency of the condenser 600 system while reducing energy consumption and structural complexity. Operators can adjust the cooling process based on actual usage requirements, thereby increasing the flexibility of the cooling process. Compared to current conventional cooling technologies, this application combines advantages such as high cooling efficiency, good cooling effect, strong operability, wide application range, low structural cost, energy conservation, and the ability to maintain a clean internal environment of the condenser 600, thus possessing broad application prospects in this field.

[0026] In this embodiment, the circulation mechanism 100 is used to discharge the hot air inside the phase shifter 600 and make it flow inside the circulating air duct 120. The air cooling mechanism 200 is used to cool the circulating air duct 120 with external cold air, thereby achieving the purpose of cooling the hot air inside the circulating air duct 120. When the cooling effect of the air cooling mechanism 200 is difficult to meet the cooling effect required by the phase shifter 600, the water cooling mechanism 300 can perform a secondary cooling of the circulating air duct 120 on the basis of air cooling to ensure the cooling effect and efficiency of this system.

[0027] Furthermore, in order to achieve contact between the circulating air duct 120 and the cooling air duct 220, the present application further includes at least one heat exchanger 400, the heat exchanger 400 including a first channel and a second channel (not shown in the figure), the first channel and the second channel being in contact with each other but not connected, the circulating air duct 120 passing through and connecting to the first channel, and the cooling air duct 220 passing through and connecting to the second channel. Figure 1As shown, this embodiment includes a heat exchanger 400, and a first channel and a second channel that are independent of each other and in contact are provided inside the heat exchanger 400. Based on this, the heat exchanger 400 can position and connect the circulating air duct 120 and the cooling air duct 220 to ensure that there is a connection between the connection positions of the circulating air duct 120 and the cooling air duct 220.

[0028] Specifically, the circulating air duct 120 in this embodiment comprises two pipes, one connected to the air inlet and the other to the air outlet of the first channel, thereby cooperating with the first channel to achieve the flow of circulating air. Furthermore, the circulation mechanism 100 in this embodiment also includes a temperature sensor (not shown) disposed within the circulating air duct 120 and connected to the air inlet of the phase shifter 600. The temperature sensor is used to detect the temperature of the heat exchange gas entering the phase shifter 600. Specifically, when the temperature sensor detects that the temperature exceeds a predetermined value, the water cooling mechanism 300 is activated for secondary cooling.

[0029] Similarly, the cooling air duct 220 also includes two pipes connected to the air inlet and air outlet of the second channel, respectively, to ensure that cooling air flows from the cooling fan 210 to the external environment. A sand removal module 230 is also included at the air inlet. The sand removal module 230 and the cooling fan 210 are sequentially arranged in the cooling air duct 220 in the direction of cooling air flow. Furthermore, the sand removal module 230 described in this embodiment has a self-cleaning function to remove dust and foreign matter from the circulating air, thereby protecting the heat exchanger 400 from the effects of dust during long-term use and ensuring the heat exchange effect of the heat exchanger 400.

[0030] See also Figure 1 As shown, the water supply assembly 310 includes a water pump 311 and at least one water supply pipe 312. One end of the water supply pipe 312 is connected to the water pump 311, and the other end is connected to at least one spray head 320. In this embodiment, there is a water supply pipe 312 and multiple spray heads 320 arranged on the same side. The water supply pipe 312 transmits cooling water through the water pump 311 to the spray heads 320. The spray heads 320 are arranged above the heat exchanger 400 so that the coolant can quickly cool the heat exchanger 400 from top to bottom. Furthermore, the water cooling mechanism 300 in this embodiment also includes a water receiving tray 330 and a box body 500. The water receiving tray 330, the spray head 320 and the heat exchanger 400 are all arranged at the bottom of the box body 500, wherein the box body 500 is used to prevent the spray water from splashing, and the water receiving tray 330 is arranged under at least one of the spray heads 320 to collect the spray water. Specifically, the water receiving tray 330 is detachably connected to the bottom of the box body 500 to facilitate the operator to recycle and process the spray water.

[0031] In addition, this embodiment also includes a control mechanism, and the circulation mechanism 100, the air cooling mechanism 200 and the water cooling mechanism 300 are respectively connected to the control mechanism. During the actual production and processing process, the operator can use the control mechanism to perform real-time regulation on the above-mentioned structures, thereby improving the flexibility of use of this system. Parameters can also be preset through the control system, thereby improving the degree of automation of this equipment.

[0032] The following describes the operating process and principle of the phase shifter cooling system in this embodiment:

[0033] When the phase regulator 600 needs to be cooled, the circulation mechanism 100 and the air cooling mechanism 200 are turned on at the same time, wherein the circulation mechanism 100 removes the heat inside the phase regulator 600 through circulating air and makes it circulate inside the circulating air duct 120, and the air cooling mechanism 200 cools the circulating air duct 120 through external cold air. During this process, the cooling channel and the circulating air duct 120 are connected through the heat exchanger 400 to ensure the air cooling efficiency and effect.

[0034] When the cooling effect of the air cooling mechanism 200 is difficult to achieve the target cooling effect, the water cooling mechanism 300 needs to be turned on for secondary cooling. At this time, the spray head 320 sprays cooling water toward the heat exchanger 400 to achieve water cooling of the circulating air duct 120, thereby reducing the temperature of the circulating air inside the circulating air duct 120, and further achieving the purpose of gradually reducing the internal temperature of the phase shifter 600 during the circulation process. Example 2

[0035] See also Figure 2 As shown, this embodiment provides another phase-shifting cooling system, which also includes a circulation mechanism 100, an air cooling mechanism 200, and a water cooling mechanism 300. Its operation process and principle are the same as those of the first embodiment and will not be described in detail here. However, the structural arrangement is different. Specifically, this embodiment includes a first heat exchanger 410 and a second heat exchanger 420. The first heat exchanger 410 and the second heat exchanger 420 are both disposed in the cooling air duct 220, and the first channel of the first heat exchanger 410 and the first channel of the second heat exchanger 420 are interconnected. The spray head 320 is disposed toward the first heat exchanger 410. Based on the above structure, the second channels of the first heat exchanger 410 and the second heat exchanger 420 can respectively communicate with the cooling channel. Furthermore, the air cooling mechanism 200 also includes a switching component 240, which is connected to the second channel of the first heat exchanger 410, and includes a first air valve 241, a second air valve 242 and a partition 243. The first air valve 241, the second air valve 242 and the partition 243 jointly enclose a switching channel, and the spray head 320 is arranged inside the switching channel.

[0036] Based on the above structural setting, when only cooling is required through the air cooling mechanism 200, the first air valve 241 and the second air valve 242 are opened, and the circulating air circulates through the two heat exchangers 400 in turn, and the cooling air cools the circulation channel from the other two second channels. On the one hand, it increases or decreases the area and time of air cooling, thereby improving the air cooling effect. On the other hand, the company can further improve the connection stability of each structure and the rationality of the layout, thereby achieving a better cooling effect on the basis of reducing its volume.

[0037] Correspondingly, the water-cooling assembly in this embodiment is located within the switching channel. When water cooling is required, the first and second air valves 241 and 242 are closed, creating a highly sealed switching channel. At this point, the air-cooling mechanism 200 only cools the second heat exchanger 420. The water-cooling mechanism 300 only cools the first heat exchanger 410, achieving simultaneous air and water cooling. Furthermore, due to the switching channel configuration, this embodiment eliminates the need for an additional water-blocking housing 500 during water cooling, further simplifying the device structure.

[0038] Furthermore, the present phase-shifting cooling system also includes a heat recovery duct (not shown). This duct is used to discharge the heated air from the cooling air duct 220 to other locations, utilizing the residual heat in the circulating air to heat other areas requiring heating. For example, when heating a factory building in winter, the heat recovery assembly directs the heated air from the second duct back into the factory building, thereby recovering and recycling the heat. Example 3

[0039] See also Figure 3 As shown, this embodiment provides another phase-shifting cooling system, comprising a first heat exchanger 410 and a second heat exchanger 420. The first channel of the first heat exchanger 410 and the first channel of the second heat exchanger 420 are interconnected. The cooling air duct 220 sequentially passes through the second air duct of the first heat exchanger 410 and the second air duct of the second heat exchanger 420. At least one of the spray heads 320 is disposed toward the second heat exchanger 420. In this embodiment, the structural volume of the cooling fan 210 is reduced, and the cooling air duct 220 is arranged in a "U" shape in the direction of gas flow. This can extend the cooling time and improve the cooling efficiency while occupying less space.

[0040] Furthermore, this embodiment includes a plurality of the spray heads 320, and in the direction of cooling air flow, the plurality of the spray heads 320 are respectively arranged on both sides of the second heat exchanger 420. Specifically, when the water pump 311 starts to operate, the upper and lower groups of spray heads 320 operate simultaneously to improve the cooling effect. It is worth noting that the two groups of spray heads 320 in this embodiment can cooperate with the "U"-shaped cooling air duct 220, that is: after the spray water is sprayed, the cooling air inside the cooling channel can synchronously drive the spray waste water to move along the cooling channel, thereby not only achieving the effect of fully combining air cooling and water cooling, but also, on the basis of double cooling, causing the cooling water to evaporate under the influence of the cooling air, and then absorb the heat of the surrounding environment, thereby further improving the cooling effect on the heat exchanger 400.

[0041] In summary, the phase shifter cooling system described in this utility model combines air and water cooling processes, significantly improving the cooling effect of the phase shifter 600 system while reducing energy consumption and structural complexity. Operators can adjust the cooling process based on actual usage requirements, thereby increasing the flexibility of the cooling process. Compared to current conventional cooling technologies, this application combines the advantages of high cooling efficiency, good cooling effect, strong operability, wide application range, low structural cost, energy conservation, and maintaining a clean internal environment of the phase shifter 600, and has broad application prospects in this field.

[0042] Obviously, the above embodiments are merely examples for clarity of explanation and are not intended to limit the implementation methods. Those skilled in the art will readily appreciate that other variations or modifications based on the above descriptions are possible. It is not necessary and impossible to enumerate all implementation methods here. Obvious variations or modifications arising therefrom remain within the scope of protection of the present invention.
