Description

[0002] At present, a large number of thermal power plants use direct air cooling systems to cooperate with steam turbine operation. The exhaust steam of the steam turbine enters the steam distribution pipe through the large-diameter main exhaust pipe, and then enters the air-cooled radiator to form condensate after being cooled by the external air. The condensate is collected and supplied to the boiler. In the process of cooling and dissipating the steam by the air-cooled radiator, the air in the environment is driven by the fan to blow to the air-cooled radiator, so that the steam is gradually cooled and condensed in the air-cooled radiator to form condensate. Since most air-cooled power stations are built in areas with cold climates and large temperature differences between day and night throughout the year, especially in the cold winter season in the north, the low temperature environment causes large-scale freezing and even cracking of the air-cooled radiator in the air-cooled island, causing accidents, reducing the operating reliability and stability of the direct air-cooled system, thereby reducing the operating stability and reliability of the air-cooled power station.

[0038] Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limiting the present invention.

[0039] Reference below Figure 1-Figure 9 An antifreeze guide device 100 for an air-cooled radiator according to an embodiment of the present invention is described.

[0040] like Figure 1-Figure 9 As shown, the antifreeze flow guide device 100 of the air-cooled radiator according to the embodiment of the present invention comprises: an antifreeze flow guide assembly 20 and an air-cooled island 10, the air-cooled island 10 is arranged below the antifreeze flow guide assembly 20, the antifreeze flow guide assembly 20 is suitable for closing and conducting the air flow outlet of the air-cooled island 10 at the top, and the air-cooled island 10 comprises: a steam distribution pipe 11 and a condensate pipe 14, a first fin tube 12 and a second fin tube 13. The steam distribution pipe 11 is arranged along a first direction (such as Figure 4 The condensate pipe 14 is arranged at the lower side of the steam distribution pipe 11; the first fin tube 12 and the second fin tube 13 are extended in the up-down direction and are connected with the steam distribution pipe 11 and the condensate pipe 14, wherein a plurality of first fin tubes 12 and a plurality of second fin tubes 13 are alternately arranged in the first direction, and the flow directions of the fluids in the first fin tubes 12 and the second fin tubes 13 are opposite.

[0041] In this embodiment, the antifreeze guide device is provided with an antifreeze guide assembly 20 and an air cooling island 10. The air cooling island 10 is provided with a steam distribution pipe 11 and a condensate pipe 14. The steam distribution pipe 11 is arranged above the condensate pipe 14. The first fin tube 12 and the second fin tube 13 are arranged in the up-down direction (such as Figure 4 The steam distribution pipe 11 and the condensate pipe 14 extend in the vertical direction as shown in the figure and are connected with the steam distribution pipe 11 and the condensate pipe 14. The structure is simple and can well meet the cooling needs of the steam. When the direct air cooling system is in operation, the steam flows along the steam distribution pipe 11 and flows into each of the first finned tubes 12 and the second finned tubes 13 respectively. In the process of the steam flowing along the first finned tubes 12 and the second finned tubes 13, the steam exchanges heat with the air through the metal surfaces of the first finned tubes 12 and the second finned tubes 13 and the arranged fins, so that the steam is gradually cooled and condensed into water. The condensed water flows from the first finned tubes 12 and the second finned tubes 13 into the condensate pipe 14, and the condensate in the condensate pipe 14 is then supplied to the boiler.

[0042] In this embodiment, the condensate pipeline 14 is arranged at the lower side of the steam distribution pipe 11, with a simple structure and reasonable arrangement. After the steam is condensed, it can flow into the condensate pipeline 14 more conveniently under the action of gravity, thereby facilitating the collection of condensate.

[0043] It can be understood that the steam is cooled and dissipated in the first fin tube 12 and the second fin tube 13, and the condensed water formed after cooling flows to the condensate pipe 14. The fluid temperature in the pipe section of the first fin tube 12 and the second fin tube 13 close to the fluid flowing out to the condensate pipe 14 is relatively low, and the heat exchange efficiency between the first fin tube 12 and the second fin tube 13 and the air is relatively high. Therefore, when the weather is cold, the first fin tube 12 and the second fin tube 13 are easily frozen or even cracked due to the low temperature, thereby causing the operation of the air-cooling island 10 to malfunction, and reducing the operating stability and reliability of the direct air cooling system in a low temperature environment.

[0044] In this embodiment, a plurality of first fin tubes 12 and a plurality of second fin tubes 13 are arranged alternately in a first direction, and the flow directions of the fluids in the first fin tubes 12 and the second fin tubes 13 are opposite. For example, during the operation of the direct air cooling system, when the steam flows along the steam distribution pipe 11 to the first fin tube 12, the steam flows from top to bottom along the first fin tube 12, and correspondingly, the steam flows from bottom to top along the second fin tube 13. Then, in the direction from top to bottom, the temperature of the fluid in the first fin tube 12 gradually decreases, and the temperature of the fluid in the second fin tube 13 gradually increases. Since the first fin tube 12 and the second fin tube 13 are arranged adjacent to each other, the first fin tube 12 and the second fin tube 13 are arranged adjacent to each other. The fluid with a higher temperature in the fin tube 12 can play a good heating and heat preservation role on the fluid with a lower temperature in the second fin tube 13 through thermal radiation, and the fluid with a higher temperature in the second fin tube 13 can play a good heating and heat preservation role on the fluid with a lower temperature in the first fin tube 12 through thermal radiation. Therefore, the first fin tube 12 and the second fin tube 13 can play a role in heat transfer and heat preservation with each other, so that the probability of freezing or cracking of the first fin tube 12 and the second fin tube 13 in a low temperature environment is greatly reduced, thereby playing a good anti-freezing effect, and making the direct air cooling system more stable and reliable when operating in a low temperature environment.

[0045] In this embodiment, the fluid flow directions in the first fin tube 12 and the second fin tube 13 are opposite, which can make the fluid temperature distribution in the first fin tube 12 and the second fin tube 13 more uniform to a certain extent, improve the heat exchange efficiency of the first fin tube 12 and the second fin tube 13, and reduce the risk of local freezing caused by uneven temperature distribution, thereby further reducing the probability of freezing or cracking of the first fin tube 12 and the second fin tube 13, and improving the operation stability and reliability of the direct air cooling system.

[0046] In this embodiment, the fluid flows in opposite directions along the first fin tube 12 and the second fin tube 13, so that the first fin tube 12 and the second fin tube 13 can form a stronger convection heat exchange effect with the air, thereby making the heat exchange efficiency of the air-cooling island 10 higher and the heat can be transferred out faster, so that the direct air cooling system can operate more efficiently.

[0047] In this embodiment, an antifreeze guide assembly 20 is arranged on the upper side of the air-cooling island 10. The antifreeze guide assembly 20 is suitable for closing and conducting the air flow outlet at the top of the air-cooling island 10. During the operation of the antifreeze guide device, air flows through the air-cooling island 10 and exchanges heat with the first fin tube 12 and the second fin tube 13 and flows upward from the air flow outlet of the antifreeze guide device. The antifreeze guide assembly 20 can close the air flow outlet when the weather is cold and the temperature is low, thereby playing a good hindering effect on the flow of the air flow, delaying the air flow with a higher temperature after heat exchange to flow out of the air flow outlet, so that the higher temperature air flow can play a good heating and heat preservation effect on the first fin tube 12, the second fin tube 13 and even the condensate pipeline 14 in the air-cooling island 10 at the air-cooling island 10, thereby playing a good antifreeze guide role, and well reducing the probability of the first fin tube 12 and the second fin tube 13 freezing or even freezing cracking due to low temperature, so that the air-cooling island 10 can operate more stably and reliably in a low temperature environment, thereby making the operation stability and reliability of the direct air cooling system better.

[0048] According to the antifreeze guide device 100 of the air-cooled radiator according to the embodiment of the present invention, by setting the antifreeze guide component 20, the antifreeze guide component 20 is suitable for closing and conducting the air flow outlet at the top of the air-cooling island 10, and the multiple first fin tubes 12 and the multiple second fin tubes 13 in the air-cooling island 10 are alternately arranged in the first direction and the flow direction of the fluid is opposite, so that the antifreeze guide device can close the air flow outlet through the antifreeze guide component 20 in a low temperature environment to delay the outflow of the air flow with a higher temperature, and the first fin tube 12 and the second fin tube 13 mutually heat the pipe section with the fluid at a lower temperature, so that the first fin tube 12 and the second fin tube 13 can be well heated and insulated, thereby greatly reducing the probability of freezing or even freezing cracking of the first fin tube 12 and the second fin tube 13, and the air-cooling island 10 can operate stably and reliably, so that the operation stability and reliability of the direct air cooling system are better.

[0049] In some embodiments of the present invention, Figure 4 As shown, the condensate pipeline 14 may include a condensate header 141 and a return pipe 142. The condensate header 141 extends along a first direction and is connected to the steam distribution pipe 11 in a second direction (eg, Figure 4 The return pipe 142 extends along the second direction and is connected to the condensate header 141. The second direction intersects with the first direction and the up and down directions in pairs. The two ends of the first fin tube 12 are respectively fixedly connected to the steam distribution pipe 11 and the condensate header 141, and are connected to the steam distribution pipe 11 and the condensate header 141. The lower end of the second fin tube 13 is connected to the steam distribution pipe 11, and the upper end of the second fin tube 13 is connected to the return pipe 142. The fluid in the second fin tube 13 is configured to flow from bottom to top.

[0050] In this embodiment, the condensate pipeline 14 includes a condensate header 141 and a return pipe 142. The condensate header 141 extends along a first direction and is spaced apart from the steam distribution pipe 11 in a second direction. Both ends of the first fin tube 12 are fixedly connected to the steam distribution pipe 11 and the condensate header 141, respectively, and the steam distribution pipe 11 and the condensate header 141 are connected. Then, the fluid in the first fin tube 12 flows from top to bottom along the first fin tube 12, and the steam flows from the first fin tube 12 along the steam distribution pipe 11 to the return pipe 142. One end of 12 connected to the steam distribution pipe 11 flows into the first fin tube 12 and flows downward toward the condensate header 141. The steam is gradually cooled in the first fin tube 12 to form condensate. The condensate flows into the condensate header 141 along the first fin tube 12 under the action of gravity. The condensate flowing into the condensate header 141 from multiple first fin tubes 12 is collected in the condensate header 141 and flows to the return pipe 142. The return pipe 142 supplies the condensate to the boiler.

[0051] In this embodiment, the lower end of the second fin tube 13 is connected to the steam distribution pipe 11, and the upper end of the second fin tube 13 is connected to the condensate header 141, so that the steam in the steam distribution pipe 11 can flow into the second fin tube 13 from the lower end of the second fin tube 13, and flow upward along the second fin tube 13 for heat exchange. The condensed water after heat exchange flows from the upper end of the second fin tube 13 to the return pipe 142, and is combined with the condensed water from the condensate header 141 to be supplied to the boiler.

[0052] In this embodiment, the fluid in the first fin tube 12 flows from top to bottom, and the fluid in the second fin tube 13 flows from bottom to top, so that the fluid with a higher temperature at the upper end of the first fin tube 12 can heat and keep warm the fluid with a lower temperature at the upper end of the second fin tube 13, and the fluid with a higher temperature at the lower end of the second fin tube 13 can heat and keep warm the fluid with a lower temperature at the lower end of the first fin tube 12, thereby effectively avoiding freezing or even freezing cracking of the lower end of the first fin tube 12 and the upper end of the second fin tube 13, thereby greatly reducing the probability of freezing or even freezing cracking of the first fin tube 12 and the second fin tube 13.

[0053] In this embodiment, the second direction intersects with the first direction and the up-down direction in pairs, which is intended to indicate that the second direction and the first direction can be arranged vertically or only intersectingly in a non-vertical arrangement, the second direction and the up-down direction can be arranged vertically or only intersectingly in a non-vertical arrangement, and the first direction and the up-down direction can be arranged vertically or only intersectingly in a non-vertical arrangement.

[0054] In one embodiment of the present invention, Figure 4As shown, the air-cooling island 10 may further include: a first connecting pipe 15, a second connecting pipe 16 and a pump body 17, wherein both ends of the first connecting pipe 15 are respectively connected to the steam distribution pipe 11 and the lower end of the second fin tube 13; both ends of the second connecting pipe 16 are respectively connected to the upper end of the second fin tube 13 and the return pipe 142; the pump body 17 is arranged on the first connecting pipe 15, and the pump body 17 is used to drive the fluid in the first connecting pipe 15 to flow to the second fin tube 13.

[0055] In this embodiment, the air-cooling island 10 is provided with a first connecting pipe 15, a second connecting pipe 16 and a pump body 17. The two ends of the first connecting pipe 15 are respectively connected to the steam distribution pipe 11 and the lower end of the second fin tube 13, and the two ends of the second connecting pipe 16 are respectively connected to the upper end of the second fin tube 13 and the condensate pipeline 14. The structure is simple. The steam in the steam distribution pipe 11 can flow into the second fin tube 13 along the first connecting pipe 15 and flow along the second fin tube 13 from bottom to top. The condensate formed after the steam dissipates heat and cools along the second fin tube 13 flows from the upper end of the second fin tube 13 along the second connecting pipe 16 to the return pipe 142. The arrangement structure of the first connecting pipe 15 and the second connecting pipe 16 is simple, which can well meet the flow requirements of steam and condensate.

[0056] In this embodiment, a pump body 17 is provided on the first connecting tube 15. The pump body 17 is used to drive the fluid in the first connecting tube 15 to flow to the second fin tube 13. The structure is simple, so that the steam from the steam distribution pipe 11 can stably and reliably flow into the second fin tube 13 and flow from bottom to top along the second fin tube 13 to the second connecting tube 16, so that the condensed water formed by the cooling of the steam in the second fin tube 13 can stably flow to the second connecting tube 16 under the drive of the pump body 17, thereby effectively avoiding the situation where the condensed water flows downward along the second fin tube 13, so that the second fin tube 13 can stably and reliably perform heat dissipation operations.

[0057] In some examples of the present invention, Figure 4 As shown, the first fin tube 12 and the second fin tube 13 can be connected between the steam distribution pipe 11 and the condensate header 141, and extend obliquely along the second direction. The first connecting pipe 15 includes: a first pipe section, a second pipe section and a connecting pipe section.

[0058] In this embodiment, the first connecting pipe 15 includes a first pipe section, a second pipe section and a connecting pipe section. The first pipe section extends in the up-down direction and the upper end is connected to the steam distribution pipe 11. The structure is simple, and the steam can flow rapidly downward along the first pipe section, so that the first connecting pipe 15 can efficiently transport steam to the second finned tube 13 to a certain extent.

[0059] The second pipe section extends along the first direction and is connected to the lower ends of the plurality of second finned tubes 13. The structure is simple and the arrangement is reasonable, which can facilitate the connection of the plurality of second finned tubes 13 with the first connecting pipe 15. The connecting pipe section is connected between the first pipe section and the second pipe section. The pump body 17 is arranged on the connecting pipe section, which facilitates the arrangement of the pump body 17 on the first connecting pipe 15. The first finned tube 12 and the second finned tube 13 extend obliquely along the second direction. The structure is simple, which can be used for the first pipe section, the second pipe section, the connecting pipe section and the first pump body 17 in the first connecting pipe 15. The first connecting pipe 15 and the first finned tube 12, the second finned tube 13, the pump body 17, the steam distribution pipe 11 and the condensate pipe 14 are arranged more conveniently, and the first finned tube 12 and the second finned tube 13 extend obliquely along the second direction, which can make the first finned tube 12 and the second finned tube 13 have a longer pipe length to a certain extent, so that the first finned tube 12 and the second finned tube 13 can better heat dissipate and cool the steam, so that the air cooling island 10 has a higher heat dissipation efficiency for the steam. Optionally, the connecting pipe section and the first pipe section and the second pipe section can be connected in an arc, so that the flow of steam in the first connecting pipe 15 can be smoother, so that the first connecting pipe 15 has a better steam transportation effect.

[0060] In some examples of the present invention, reference Figure 4 As shown, the number of condensate headers 141 can be two, and the two condensate headers 141 are respectively arranged on both sides of the steam distribution pipe 11 in the second direction, and the two ends of the return pipe 142 are respectively connected to the two condensate headers 141, and the multiple first fin tubes 12 and the second fin tubes 13 alternately arranged along the first direction form a fin tube group, and the two fin tube groups are respectively connected between the steam distribution pipe 11 and the two condensate headers 141. The first connecting pipe 15 and the pump body 17 are arranged one-to-one with the fin tube groups, and the second connecting pipe 16 may include: a third pipe segment and a fourth pipe segment, the third pipe segment extends along the first direction, and is located between the two condensate headers 141 in the second direction, and the third pipe segment is connected to the upper ends of the multiple second fin tubes 13 in the two fin tube groups; the fourth pipe segment extends in the up-down direction, the upper end of the fourth pipe segment is connected to the third pipe segment, and the lower end of the fourth pipe segment is connected to the return pipe 142.

[0061] In the present embodiment, there are two condensate headers 141, and the two condensate headers 141 are respectively arranged on both sides of the steam distribution pipe 11 in the second direction. There are two groups of fin tube groups formed by the first fin tube 12 and the second fin tube 13, and each group of fin tube groups is connected between the steam distribution pipe 11 and the two condensate headers 141. By way of example, both ends of the first fin tube 12 and both ends of the second fin tube 13 in the fin tube group can be fixedly connected to the steam distribution pipe 11 and the condensate tanks, respectively. The two groups of fin tube groups, the steam distribution pipe 11 and the two condensate headers 141 can cooperate to form a triangular structure, so that the steam distribution pipe 11 and the two groups of fin tube groups and the condensate pipeline 14 can form a stable connection structure, so that the steam or condensate can flow stably in each pipeline in the air-cooling island 10.

[0062] When the air-cooling island 10 is in operation, the steam in the steam distribution pipe 11 can flow along the first fin tube 12 and the second fin tube 13 in the two fin tube groups at the same time. In the two fin tube groups, the condensed water formed by the heat dissipation and cooling of the steam in the first fin tube 12 flows into the two condensate headers 141 respectively, and the condensed water formed by the heat dissipation and cooling of the steam in the second fin tube 13 flows into the return pipe 142. In this embodiment, two groups of fin tube groups are provided to cooperate with the distribution pipes and the two condensate tanks to well meet the heat dissipation and cooling needs of the air-cooling island 10. The two groups of fin tube groups cooperate to dissipate the heat and cool the steam in the steam distribution pipe 11, which can greatly improve the heat dissipation efficiency of the air-cooling island 10, so that the direct air cooling system can operate efficiently to dissipate heat to meet the cooling needs of the air-cooling power station.

[0063] In this embodiment, the first connecting pipe 15 and the pump body 17 are arranged correspondingly to the fin tube group, that is, in this embodiment, two first connecting pipes 15 are arranged, and the two first connecting pipes 15 are respectively connected to the steam distribution pipe 11 and the lower ends of the plurality of second fin tubes 13 in the two fin tube groups, and each first connecting pipe 15 is provided with a pump body 17.

[0064] In this embodiment, the second connecting pipe 16 includes a third pipe section and a fourth pipe section. The third pipe section extends along the first direction and is connected to the upper ends of multiple second fin tubes 13 in the two fin tube groups. The structure is simple, so that the second fin tubes 13 in the two groups of fin tube groups can transport condensed water through one second connecting pipe 16, thereby reducing the number of second connecting pipes 16 arranged, making the air-cooling island 10 more convenient and less costly to arrange.

[0065] In this embodiment, the fourth pipe section extends up and down and its two ends are respectively connected to the third pipe section and the return pipe 142, which can facilitate the condensed water to flow quickly along the fourth pipe section to the return pipe 142, so that the second connecting pipe 16 can play a good role in transporting the condensed water, and can avoid the accumulation of condensed water in the fourth pipe section and the freezing of the pipeline due to low temperature, so that the second connecting pipe 16 can perform the transportation operation stably.

[0066] In some examples of the present invention, reference Figure 4 As shown, the third pipe section can be arranged below the steam distribution pipe 11 and close to the steam distribution pipe 11. In this way, the steam in the steam distribution pipe 11 can play a certain role in heating and heat preservation of the condensed water in the third pipe section, thereby greatly reducing the probability of freezing or even cracking of the second connecting pipe 16 at low temperatures, so that the air-cooling island 10 can operate more stably and reliably in a low-temperature environment.

[0067] In some examples of the present invention, reference Figure 4 and Figure 5 As shown, the air-cooling island 10 may further include: a first branch pipe 18 and a second branch pipe 19, the first branch pipe 18 extends along the second direction and is connected between the lower end of the second fin tube 13 and the first connecting pipe 15, the first connecting pipe 15 is communicated with the second fin tube 13 through the first branch pipe 18, and a plurality of first branch pipes 18 are arranged in a one-to-one correspondence with a plurality of second fin tubes 13; the second branch pipe 19 extends along the second direction and is connected between the upper end of the second fin tube 13 and the second connecting pipe 16, the second connecting pipe 16 is communicated with the second fin tube 13 through the second branch pipe 19, and a plurality of second branch pipes 19 are arranged in a one-to-one correspondence with a plurality of second fin tubes 13.

[0068] In this embodiment, the air-cooling island 10 is provided with a plurality of first branch pipes 18 and a plurality of second branch pipes 19. The plurality of first branch pipes 18 and the plurality of second branch pipes 19 are arranged one-to-one corresponding to the plurality of second fins. The first branch pipe 18 extends along the second direction and is connected to the lower end of the second fin tube 13 and the first connecting pipe 15. The second branch pipe 19 extends along the second direction and is connected to the upper end of the second fin tube 13 and the second connecting pipe 16. The structure is simple, so that the plurality of second fin tubes 13 can be conveniently connected and assembled with the first connecting pipe 15 and the second connecting pipe 16.

[0069] In some embodiments of the present invention, reference Figure 1 and Figure 2 As shown, the antifreeze guide device can also include: an air guide plate 30, a heat dissipation fan 40, a wind shield plate 50 and a support plate 60, the air guide plate 30 extends in a horizontal direction, the air-cooling island 10 is arranged on the air guide plate 30, the air guide plate 30 is provided with an air inlet, and the air inlet faces the air-cooling island 10; the heat dissipation fan 40 is installed on the lower side of the air guide plate 30, and the air outlet of the heat dissipation fan 40 is arranged toward the air inlet; the air shield plate 50 extends in an up-down direction, the two air shield plates 50 are respectively arranged on both sides of the air guide plate 30 in the second direction, and the upper end of the air shield plate 50 is connected to the air guide plate 30; the support plate 60 extends in an up-down direction, the two support plates 60 are respectively arranged on both sides of the air-cooling island 10 in the second direction and are connected to the wind shield plate 50, the two support plates 60 cooperate to define the air flow outlet on the upper side of the air-cooling island 10, and the antifreeze guide assembly 20 is installed on the two support plates 60.

[0070] In this embodiment, the antifreeze guide device is also provided with an air guide plate 30, which extends in the horizontal direction and is provided with an air inlet. The air-cooling island 10 is arranged on the air guide plate 30, and the air inlet is arranged toward the air cooling. The structure is simple. The air guide plate 30 can play a good supporting role for the air-cooling island 10, and play a certain guiding role in the flow of air, optimize the distribution of air, and make the air pass through the air-cooling island 10 more evenly at the air-cooling island 10, so that the air-cooling island 10 can have better heat dissipation efficiency.

[0071] The heat dissipation fan 40 is installed on the lower side of the air guide plate 30 and the air outlet is arranged toward the air inlet. When the antifreeze guide device is operating, the heat dissipation fan 40 drives the air from bottom to top through the air inlet to flow toward the air-cooling island 10, so that the air exchanges heat with the first fin tube 12 and the second fin tube 13. After the heat exchange, the heated air flow flows upward out of the air flow outlet. The heat dissipation fan 40 can enhance the flow of the air flow, so that the first fin tube 12 and the second fin tube 13 in the air-cooling island 10 can more efficiently dissipate heat and cool the steam, thereby allowing the air-cooling island 10 to operate efficiently.

[0072] In this embodiment, wind shields 50 are provided on both sides of the wind guide plate 30 in the second direction. The upper ends of the wind shields 50 are connected to the wind guide plate 30, and have a simple structure. They can cooperate with the support plate 60 to better support the air-cooling island 10. The wind shields 50 extend in the up and down directions, and can effectively prevent the influence of external wind and other environmental factors on the air-cooling island 10 on both sides of the heat dissipation fan 40 along the second direction, so that the heat dissipation fan 40 can operate more stably to supply air to the air-cooling island 10, so that the air flow used for cooling can stably flow upward from the air inlet through the air-cooling island 10, so that the air-cooling island 10 can operate stably and maintain an efficient heat dissipation and cooling effect.

[0073] In this embodiment, support plates 60 are provided on both sides of the air-cooling island 10 in the second direction. The support plates 60 extend in the up-down direction and are connected to the wind shield 50. The two support plates 60 cooperate to define an air flow outlet on the upper side of the air-cooling island 10, that is, the upper ends of the support plates 60 extend beyond the steam distribution pipe 11 of the air-cooling island 10 in the up-down direction. The upper ends of the two support plates 60 cooperate to form an air flow outlet on the upper side of the air-cooling island 10. The support plates 60 can play a good guiding role in the air flow in the air-cooling area, and can well prevent the influence of external air flow and other factors on the air-cooling island 10, so that the air flow can flow through the air-cooling island 10 more stably, so that the first fin tube 12 and the second fin tube 13 in the air-cooling island 10 can better exchange heat and cool with the air, so that the antifreeze guide device can operate more stably and the heat dissipation and cooling effect of the air-cooling island 10 can be more stable.

[0074] In this embodiment, the antifreeze guide assembly 20 is installed on two support plates 60, which has a simple structure. The support plates 60 can provide a good installation and layout position for the antifreeze guide assembly 20, so that the antifreeze guide assembly 20 is more convenient to arrange in the antifreeze guide device.

[0075] When the weather is relatively cold, the antifreeze guide component 20 closes the air flow outlet so that the air flow after heat exchange can be delayed from flowing out. Air with a higher temperature can accumulate in the space between the antifreeze guide component 20, the two support plates 60 and the air guide plate 30, thereby having a good insulation effect on the air-cooling island 10 and greatly reducing the probability of freezing or cracking of the first fin tube 12 and the second fin tube 13.

[0076] In one embodiment of the present invention, reference Figure 6-Figure 9 As shown, the antifreeze deflector assembly 20 may include: a fixed plate 21 and a transmission rod 22, a rotating rod 25 and a transmission mechanism, a wind shield 26 and a connecting member and a driving member 27. The fixed plate 21 and the transmission rod 22 both extend in the first direction, and the fixed plates 21 are fixed on the two support plates 60. The transmission rod 22 is rotatably arranged on the fixed plate 21; the rotating rod 25 extends in the second direction and both ends are rotatably arranged on the fixed plate 21 respectively. The rotating rod 25 is transmission-connected to the transmission rod 22 through a transmission structure 23. The number of the rotating rods 25 is two, and the two rotating rods 25 are arranged at intervals in the first direction; one end of the wind shield 26 is wound around one of the rotating rods 25, one end of the connecting member is wound around the other of the rotating rods 25, the other end of the wind shield 26 is connected to the other end of the connecting member, and the two rotating rods 25 rotate synchronously and in the same direction; the driving member 27 is transmission-connected to the transmission rod 22.

[0077] In this embodiment, the antifreeze guide assembly 20 is provided with a fixed plate 21 and a transmission rod 22. The fixed plates 21 are fixed on the two support plates 60, so the number of the fixed plates 21 is two, and the two fixed plates 21 can be respectively fixed on the upper ends of the two support plates 60. The transmission rod 22 extends along the first direction and is transmissively arranged on the fixed plate 21. Exemplarily, the number of the transmission rods 22 can be two, and the two transmission rods 22 are respectively arranged on the two fixed plates 21, and the two transmission rods 22 and the two fixed plates 21 are respectively located on both sides of the airflow outlet.

[0078] The antifreeze guide assembly 20 is also provided with a rotating rod 25 and a transmission mechanism. The rotating rod 25 extends along the second direction and both ends are rotatably arranged on the fixed plate 21. The rotating rod 25 is connected to the transmission rod 22 through the transmission structure 23. When the transmission rod 22 rotates, the rotating rod 25 can be driven to rotate. The two rotating rods 25 are arranged at intervals in the first direction. Specifically, the two rotating rods 25 can be arranged on both sides of the airflow outlet. One end of the windshield 26 is wound around one of the rotating rods 25, one end of the connecting member is wound around the other of the rotating rods 25, and the other end of the windshield 26 is connected to the other end of the connecting member. The two rotating rods 25 rotate synchronously and in the same direction. The driving member 27 is connected to the transmission rod 22. The structure is simple and can well meet the needs of the antifreeze guide assembly 20 to close and open the airflow outlet.

[0079] When the weather is cold, the driving member 27 drives the transmission rod 22 to rotate, so that the transmission rod 22 can drive the two rotating rods 25 to rotate in the same direction through the transmission structure 23, so that the wind shield 26 can be unwound from the rotating rod 25 and the connecting member can be reeled in on the rotating rod 25, and the other end of the wind shield 26 is stably unfolded along the first direction under the connection and reeling action of the connecting member, so that the wind shield 26 closes the airflow outlet to block the outflow of airflow, and when the airflow outlet does not need to be closed, the driving member 27 can drive the rotating rod 25 to rotate in the opposite direction, so that the wind shield 26 is reeled into the rotating rod 25, so that the airflow outlet is conductive.

[0080] In some examples of the present invention, reference Figure 6 , Figure 8 and Fig. 9 As shown, the antifreeze guide assembly 20 may further include a guide structure 24, the guide structure 24 includes: a fixing member 241 and a guide rod 242, the fixing member 241 is arranged on the fixing plate 21, the guide rod 242 extends along the first direction and is fixed on the fixing member 241, the transmission rod 22 is passed through the fixing member 241 along the first direction and is rotatably arranged on the fixing member 241, the transmission structure 23 includes: a slider 231 and a transmission gear 232 and a transmission wheel 233 and a transmission belt 234, the slider 231 extends along the first direction and is fixed on the fixing member 241. The slider 231 is threadedly connected to the transmission rod 22 so that the transmission rod 22 drives the slider 231 to move along the first direction by rotating. The slider 231 is provided with a rack portion 2311 extending along the first direction. Transmission gears 232 are provided at both ends of the rotating rod 25. The rack portion 2311 is meshed with the transmission gear 232 for transmission. The transmission wheel 233 is provided at one end of the transmission rod 22. The transmission wheels 233 on the two transmission rods 22 are connected through a transmission belt 234.

[0081] In this embodiment, the antifreeze guide assembly 20 is provided with a guide structure 24, and the guide structure 24 includes a fixing member 241 and a guide rod 242. The fixing member 241 is arranged on the fixing plate 21, and the guide rod 242 extends along a first direction and is fixed on the fixing member 241. The structure is simple, so that the guide rod 242 can be conveniently and stably fixed on the fixing plate 21 through the fixing member 241. The transmission rod 22 is passed through the fixing member 241 along the first direction and is rotatably arranged on the fixing member 241. The structure is simple and can meet the use requirements of the transmission rod 22.

[0082] The transmission structure 23 includes a slider 231 and a transmission gear 232. The slider 231 is movably arranged on the guide rod 242 along the first direction and is threadedly connected to the transmission stem. Specifically, the slider 231 can be provided with a through hole, and the guide rod 242 is penetrated in the through hole. The slider 231 is also provided with a threaded hole that is threadedly matched with the transmission rod 22. The transmission rod 22 is correspondingly provided with an external thread. The transmission rod 22 is threadedly matched with the threaded hole of the slider 231. When the driving member 27 drives the rotating rod 25 to rotate, the slider 231 can move along the guide rod 242 in the first direction.

[0083] In this embodiment, the slider 231 is provided with a rack portion 2311 extending along the first direction, and the two ends of the rotating rod 25 are provided with transmission gears 232. The two ends of the rotating rod 25 are respectively meshed with the rack portions 2311 of the sliders 231 on the two transmission rods 22 for transmission. When the slider 231 moves along the first direction, the rack portion 2311 drives the transmission gear 232 to rotate, thereby driving the rotating rod 25 to rotate. The rack and gear meshing transmission method and the threaded transmission method enable the transmission rod 22 to stably and reliably drive the rotating rod 25 to rotate through the slider 231 and the transmission gear 232, thereby making the antifreeze deflection component 20 more stable and reliable during operation.

[0084] In this embodiment, the transmission structure 23 also includes a transmission wheel 233 and a transmission belt 234. The transmission wheel 233 is arranged at one end of the transmission rod 22. The transmission wheels 233 on the two transmission rods 22 are connected by the transmission belt 234. The structure is simple, and the two transmission rods 22 can be more stably rotated synchronously to drive the two rotating rods 25 to rotate stably and synchronously. For example, when the driving member 27 drives one transmission rod 22 to rotate, the other transmission rod 22 can be rotated synchronously with the transmission belt 234 through the transmission wheel 233, so that the two transmission rods 22 can synchronously drive the slider 231 to move on both sides of the rotating rod 25 in the second direction, and then both ends of the rotating rod 25 can be driven to rotate by the slider 231, so that the rotating rod 25 can rotate more stably and reliably. In this embodiment, by setting the transmission wheel 233 and the transmission belt 234, the driving member 27 only needs to drive one of the two transmission rods 22 to make the rotating rod 25 rotate stably, thereby reducing the number of driving members 27 and reducing the cost of the antifreeze guide assembly 20.

[0085] In some embodiments of the present invention, reference Figure 1 and Figure 6 As shown, the antifreeze guide device can also include a rain shield 80, which extends along a first direction and has its lower end fixedly connected to the fixed plate 21, and its upper end extends upwardly and obliquely toward the air-cooling island 10 along a second direction.

[0086] In this embodiment, a rain shield 80 is provided to cover components such as the transmission rod 22 and the guide rod 242. The structure is simple and can well prevent rainwater from entering the transmission structure 23 and the drive member 27 of the antifreeze guide assembly 20, thereby protecting the electrical equipment such as the drive member 27, so that the antifreeze guide assembly 20 can operate more stably and reliably. The upper end of the rain shield 80 extends upward along the second direction toward the air-cooled island 10, which can play a good role in guiding rainwater, so that rainwater flows along the rain shield 80 to the outside of the antifreeze guide device, thereby avoiding the occurrence of water accumulation, so that the rain shield 80 can stably play a good rain shielding effect. Exemplarily, the rain shield 80 can have a U-shaped structure with an opening along the second direction toward the air-cooled island 10.

The transmission rod 22 can be rotatably connected to the fixing seat, wherein one end of the transmission rod 22 passes through the fixing seat and is installed with a transmission wheel 233. The transmission wheels 233 provided on the two transmission rods 22 are connected through a transmission belt 234.

[0100] The slider 231 is movably mounted on the guide rod 242 along the first direction and is threadedly connected to the transmission rod 22. The slider 231 is provided with a rack portion 2311, which extends along the first direction. The rotating rod 25 extends along the second direction. The two rotating rods 25 are arranged at intervals in the first direction. The two ends of the rotating rod 25 are drivably fixed on the fixed plate 21 through a rotating seat. The two ends of the rotating rod 25 are provided with a transmission gear 232, which meshes with the rack portion 2311 of the slider 231 for transmission. One of the two transmission rods 22 is provided with a first bevel gear 221, which is arranged at the middle position of the transmission rod 22. The driving member 27 is a driving motor, which meshes with the first bevel gear 221 through the second bevel gear 271 in the reduction structure for outputting power, so that the driving motor can more stably drive the transmission rod 22 to rotate and transmit power to the sliders 231 at both ends of the transmission rod 22.

[0101] The windshield 26 is a rain curtain, one end of which is wound around a rotating rod 25, and the connecting member can be a traction rope, one end of which is wound around another rotating rod 25 and the other end is connected to the other end of the windshield 26. The number of connecting members can be multiple to stably connect the windshield 26.

[0102] There are two rain shields 80 , which are fixed on two fixing plates 21 respectively. The transmission rod 22 , the driving member 27 , the guide rod 242 , the fixing member 241 , the fixing seat, the rotating seat, the transmission gear 232 and the transmission wheel 233 are all covered in the rain shield 80 .

[0103] When the weather is cold and the temperature is low, on the one hand, the antifreeze guide assembly 20 is in operation, and the driving member 27 drives the transmission rod 22 to rotate, and at the same time, the transmission rod 22 drives another transmission rod 22 to rotate synchronously through the transmission wheel 233 and the transmission belt 234, so that the slider 231 moves along the first direction and drives the two rotating rods 25 to rotate synchronously, and the wind shield 26 gradually expands along the first direction and closes the air flow outlet, so that the higher temperature air after heat exchange in the air-cooling island 10 can be retained in the air-cooling island 10 to keep the first fin tube 12 and the second fin tube 13 warm. At the same time, the wind shield 26 closes the air flow outlet, which can play a role in preventing rain and snow. On the other hand, the pump body 17 drives the steam in the steam distribution pipe 11 to enter the second fin tube 13 along the first connecting pipe 15, and the steam flows from bottom to top along the second fin tube 13 to dissipate heat, and the steam flows from top to bottom along the first fin tube 12 to dissipate heat, so that the first fin tube 12 and the second fin tube 13 can heat and keep each other warm, thereby greatly reducing the probability of freezing or even cracking of the first fin tube 12 and the second fin tube 13, so that the air-cooling island 10 can operate more stably and reliably in a low-temperature environment, thereby allowing the direct air cooling system to operate more stably and reliably.

[0104] In this embodiment, an antifreeze guide component 20 is provided, and the antifreeze guide component 20 is suitable for closing and conducting the air flow outlet at the top of the air-cooling island 10. The multiple first fin tubes 12 and the multiple second fin tubes 13 in the air-cooling island 10 are alternately arranged in the first direction and the flow direction of the fluid is opposite, so that the antifreeze guide device can close the air flow outlet through the antifreeze guide component 20 in a low temperature environment to delay the outflow of the air flow with a higher temperature. The first fin tube 12 and the second fin tube 13 mutually heat the pipe section with the fluid at a lower temperature, so that the first fin tube 12 and the second fin tube 13 can be well heated and insulated, thereby greatly reducing the probability of freezing or even freezing cracking of the first fin tube 12 and the second fin tube 13, and the air-cooling island 10 can operate stably and reliably, thereby making the operation stability and reliability of the direct air cooling system better.
