[0024] The following describes the embodiments of the present invention through specific embodiments, and those skilled in the art can easily understand other advantages and effects of the present invention from the contents disclosed in this specification. The present invention can also be implemented or applied through other different specific embodiments, and the details in this specification can also be modified or changed in various ways based on different viewpoints and applications without departing from the spirit of the present invention. It should be noted that the following embodiments and features in the embodiments can be combined with each other without conflict.

[0025] It should be noted that the illustrations provided in the following embodiments are only schematic illustrations of the basic concept of the present invention. The illustrations only show components related to the present invention rather than being drawn according to the number, shape and size of components in actual implementation. In actual implementation, the type, quantity and proportion of each component may be changed arbitrarily, and the component layout may also be more complicated.

[0026] The heat dissipation system of the frequency converter for the water supply pump for waste incineration power generation of the present invention centrally distributes the cold air cooled by the water source cooling unit by arranging an automatic conveying device, and detects the temperature of the upper and lower areas inside the frequency converter room by a temperature measurement and adjustment component, so as to adjust the position of the electric push rod according to the upper and lower temperature differences, thereby adjusting the position of the isolation seat, so as to adjust the space size of the upper and lower air collecting chambers, so as to facilitate the output of cold air with different cooling amounts in the upper and lower areas according to the actual temperature difference, thereby realizing accurate heat dissipation and cooling of different areas inside the frequency converter room, effectively reducing the occurrence of uneven heat dissipation and improving the heat dissipation efficiency.

[0027] like Figures 1 to 8 As shown, in one embodiment, the present invention discloses a heat dissipation system for a feedwater pump inverter for waste incineration power generation, including a heat concentrator 7 installed at the top of a frequency conversion room 1, a plurality of frequency converters 2 are arranged inside the frequency conversion room 1, a hot air output pipe 3 is connected to one side of the top of the frequency conversion room 1, a water source cooling unit 4 located outside the frequency conversion room 1 is connected to the end of the hot air output pipe 3, a cold air output pipe 5 is connected to the output end of the water source cooling unit 4, an automatic conveying device 6 located inside the frequency conversion room 1 is connected to the end of the cold air output pipe 5, and the automatic conveying device 6 is used to output different cold air amounts according to different temperatures inside the frequency conversion room 1;

[0028] Among them, reference Figure 2 The automatic conveying device 6 includes a corner air collecting seat 61 installed at the corner of the frequency conversion chamber 1, and an isolation seat 62 is installed inside the corner air collecting seat 61, so that the inside of the corner air collecting seat 61 is divided into an upper air collecting chamber 67 and a lower air collecting chamber 68 through the isolation seat 62. A transfer box 63 is installed at the end of the cold air output pipe 5, and a separation valve plate 64 is arranged inside the transfer box 63. One end of the separation valve plate 64 is in contact with the side wall of the transfer box 63, and the other end is fixedly connected to the isolation seat 62. The isolation seat 62 slides with the side wall of the corner air collecting seat 61. The isolation seat 62 is dynamically connected, and the bottom end of the isolation seat 62 is connected to an electric push rod 65, so that the position of the isolation seat 62 inside the corner air collecting seat 61 can be adjusted by the electric push rod 65, and the outer wall of the corner air collecting seat 61 is connected to an air guide port 66 that fits the side wall of the frequency conversion chamber 1, so that cold air can be output to the interior of the frequency conversion chamber 1 through the air guide port 66, and the outer wall of the corner air collecting seat 61 is installed with a temperature measurement adjustment component 8, and the temperature measurement adjustment component 8 adjusts the position of the electric push rod 65 according to the upper and lower temperature difference in the frequency conversion chamber 1 to adjust the position of the isolation seat 62.

[0029] When the frequency conversion room 1 needs to be cooled, the hot air inside the frequency conversion room 1 is collected by the heat concentrator 7, and outputted to the water source cooling unit 4 outside the frequency conversion room 1 through the hot air output pipe 3 for cooling. The water source cooling unit 4 generates cold air after cooling the hot air and outputs the cold air through the cooling output pipe 5. The output cold air is automatically transported to various positions inside the frequency conversion room 1 through the automatic conveying device 6 to dissipate the heat inside the frequency conversion room 1, thereby quickly dissipating the heat of the frequency conversion room 1, reducing the operating temperature of the frequency converter 2 inside the frequency conversion room 1, and protecting the frequency converter 2.

[0030] In this embodiment, since hot air has the characteristic of flowing upward, after the inverter 2 has been working for a long time, the problem of local temperature difference is easy to occur inside the inverter room 1, and the problem of low heat dissipation efficiency is easy to occur if the traditional heat dissipation method is directly adopted. Therefore, in the present application scheme, the temperature of the upper and lower spaces inside the inverter room 1 is detected by setting a temperature measurement and adjustment component 8, so as to adjust the position of the electric push rod 65 according to the detection result. Since the electric push rod 65 is directly connected to the isolation seat 62, the movement of the electric push rod 65 will directly drive the movement of the entire isolation seat 62, thereby adjusting the position of the isolation seat 62 and the partition valve plate 64, so as to adjust the capacity and air intake rate of the upper air collecting chamber 67 and the lower air collecting chamber 68, and finally spray it to the corresponding position through the air guide port 66 at the corresponding position, so that the higher the temperature area, the larger the capacity and air intake rate of the corresponding air collecting chamber, and the higher the cooling efficiency. While ensuring the cooling effect, the use of cooling air is effectively reduced and the power consumption is reduced.

[0031] Specifically, the frequency conversion chamber 1 is divided into an upper space and a lower space with the vertical height center as the boundary. When the temperature measuring and adjusting component 8 detects the temperature inside the frequency conversion chamber 1, when it is detected that the temperature of the upper space is higher than the temperature of the lower space, the temperature measuring and adjusting component 8 controls the electric push rod 65 to move downward, thereby driving the isolation seat 62 and the separation valve plate 64 to move downward, thereby increasing the space of the upper air collecting chamber 67. Since the separation valve plate 64 divides the interior of the transfer box 63 into an upper transfer chamber 631 and a lower transfer chamber 632, as the separation valve plate 64 moves downward, the space of the upper transfer chamber 631 area above the interior of the transfer box 63 is increased to increase the air intake efficiency of the upper air collecting chamber 67, so that the cold air output from the cold air output pipe 5 can quickly enter the upper air collecting chamber 67 above the isolation seat 62 for heat dissipation, thereby improving the cooling effect and rate of the space above the frequency conversion chamber 1, and at the same time, while ensuring the cooling effect, reducing the amount of cold air used in the lower space, saving energy consumption.

[0032] In some embodiments, reference Figure 8The temperature measurement and adjustment component 8 includes a plurality of sensor groups 81 installed outside the frequency conversion chamber 1, and the sensor group 81 is used to detect temperature information of different upper and lower positions of the frequency conversion chamber 1. The sensor group 81 is communicatively connected with a calculation unit 82, and the calculation unit 82 is used to calculate the temperature difference between the upper and lower positions according to the temperature information, and calculate the adjustment ratio of the upper space and the lower space of the frequency conversion chamber 1 according to the temperature difference. The calculation unit 82 is electrically connected with a controller 83, and the controller 83 is electrically connected to the electric push rod 65, and is used to adjust the length of the electric push rod 65 according to the adjustment ratio to adjust the position of the isolation seat 62, thereby adjusting the exhaust rate of the upper air collecting chamber 67 and the lower air collecting chamber 68. When the average temperature of the space above the frequency conversion chamber 1 is higher than the average temperature of the space below, the controller 83 pushes the electric push rod 65 to contract downward, and when the average temperature of the space above the frequency conversion chamber 1 is lower than the average temperature of the space below, the controller 83 pushes the electric push rod 65 to move upward.

[0033] The calculation process of the adjustment ratio satisfies the following formula:

[0034]

[0035] Wherein, S represents the adjustment ratio, A represents the first average temperature, and B represents the second average temperature.

[0036] Specifically, the temperature measurement and adjustment component 8 is installed at various upper and lower positions inside the frequency conversion chamber 1 to collect temperature information at various positions, and the temperature information at various positions is summarized and calculated through the calculation unit 82 to calculate the first average temperature A of the upper space inside the frequency conversion chamber 1 and the second average temperature B of the lower space, and the difference M and the average value N between the two are calculated, and the adjustment ratio S=M / N is calculated according to the difference M and the average value N, so that the controller 83 can adjust the position of the electric push rod 65 according to the calculated adjustment ratio S to adjust the exhaust rate and capacity of the upper air collecting chamber 67 and the lower air collecting chamber 68.

[0037] Exemplarily, when the length of the electric push rod 65 is 1.5m, the isolation seat 62 and the partition valve plate 64 are both in the middle position, the upper air collecting chamber 67 and the lower air collecting chamber 68 are of the same size, and the upper transfer chamber 631 and the lower transfer chamber 632 are also of the same size. When the average temperature of the upper space inside the frequency conversion chamber 1 is calculated to be 42°C, and the average temperature of the lower space is 38°C, the overall difference M=4 is calculated, and the average value N=40 is calculated, then the adjustment ratio is calculated to be 10%. Since the temperature of the upper space is greater than the temperature of the lower space, the length of the electric push rod 65 is adjusted downward by 0.15m to correspondingly adjust the exhaust rates of the upper air collecting chamber 67 and the lower air collecting chamber 68, so as to specifically improve the cooling effect of different areas, improve the cooling efficiency, and reduce power consumption.

[0038] In some other embodiments, reference Figure 3 , Figure 4 and Figure 5 The heat concentrator 7 includes a concentrator seat 71 installed at the top of the inverter 2. The concentrator seat 71 is conductively connected to the hot air output pipe 3. A collection plate 72 is installed at the bottom of the concentrator seat 71. An annular groove 73 is provided at the bottom of the collection plate 72. A sliding seat 74 is slidably connected inside the annular groove 73. A heat absorbing seat 75 is connected to the bottom of the sliding seat 74. The heat absorption seat 75 includes an arc seat 751 which is directly opposite to the air outlet 21 of the inverter 2, and an arc plate 752 is provided on the side of the arc seat 751 which is directly opposite to the air outlet 21, and a plurality of air inlets 753 are provided on the surface of the arc plate 752, and heat-conducting fins 754 are installed between adjacent air inlets 753, and a condensing groove 755 which is connected to the heat-conducting fins 754 is installed inside the arc seat 751, and the condensing groove 755 is filled with coolant, and a cooling cylinder 611 which is connected to the condensing groove 755 is installed inside the corner air collecting seat 61, and the bottom end of the cooling cylinder 611 is connected to the condensing groove 755 through a connecting hose 612, and a water pump is installed at one end of the connecting hose 612 located at the cooling cylinder 611.

[0039] In this embodiment, in order to ensure the heat collection effect of the heat concentrator 7 on the inside of the frequency conversion chamber 1, a concentrator seat 71 is installed on the top of the frequency converter 2, and the hot air released by the frequency converter 2 is collected through the collection plate 72 at the bottom of the concentrator seat 71, so as to facilitate the subsequent rapid cooling of the hot air generated by the water source cooling unit 4. Specifically, according to the installation position of the frequency converter 2 inside the frequency conversion chamber 1, the position of the sliding seat 74 is adjusted, so that the heat absorption seat 75 is adjusted to the position facing the air outlet 21 of the frequency converter 2. The heat absorption seat 75 absorbs the hot air generated by the frequency converter 2 through multiple air inlets 753 arranged on the surface of the arc plate 752 facing the air outlet 21. The hot air directly enters the inside of the concentrator seat 71 through the air inlet 753, and then is output to the outside through the hot air output pipe 3. In the process of hot air entering the air inlet 753 and the hot air output pipe 3, the coolant in the condensation tank 755 absorbs part of the heat, and the evaporated coolant is discharged into the external cooling cylinder 611. After being cooled by the cooling device inside the cooling cylinder 611, the coolant flows back to the condensation tank 755, achieving preliminary cooling of the heat, thereby effectively reducing the cooling time of the subsequent water source cooling unit 4.

[0040] Among them, the cooling device for the coolant inside the cooling cylinder 611 adopts the content of the existing technology, and this solution does not involve its improvement, which will not be repeated here.

[0041] In some embodiments, reference Figure 6 and Figure 7 The water source cooling unit 4 includes a water-cooling case 41 and an air collecting box 42. The air collecting box 42 is installed at the top of the water-cooling case 41 and is conductively connected to the hot air output pipe 3. The bottom of the water-cooling case 41 is connected to a water circulation component 43. An evaporator 44 is installed on the side wall of the air collecting box 42. The evaporator 44 is conductively connected to the water circulation component 43, and an exhaust port 45 facing the evaporator 44 is provided on the side of the air collecting box 42. The exhaust port 45 is conductively connected to the cold air output pipe 5.

[0042] After the extracted hot air is output through the hot air output pipe 3, it enters the air collecting box 42, and then is input into the evaporator 44 for cooling and evaporation to generate cold air, and the generated cold air is output to the cold air output pipe 5 through the exhaust port 45, and the cold air is output through the cold air output pipe 5. The evaporator 44 is connected with the water circulation component 43, so that cold water is input into the evaporator 44 to generate cold air, and the heated hot water is discharged, so that the evaporator 44 continuously generates cold air to cool and dissipate the frequency conversion chamber 1. Since the water circulation component 43 inputs cooling water and discharges hot water to achieve continuous refrigeration of the evaporator 44 is the content of the prior art, the present application scheme does not involve improvements to the evaporator 44 and the water circulation component 43 themselves, which will not be repeated here.

[0043] In some other embodiments, a plurality of diverters 441 are installed on the outer wall of the evaporator 44, and the outer ends of the plurality of diverters 441 are conductively connected through a connecting tube 442, and the outer wall of the connecting tube 442 is connected to a mixing tube 443 located inside the air collecting box 42, and an isolation plate 444 is installed at the center of the mixing tube 443, and the isolation plate 444 divides the interior of the mixing tube 443 into a first mixing chamber 445 and a second mixing chamber 446 which are conductively connected to each other at the bottom ends, the connecting tube 442 is conductively connected to the top side of the first mixing chamber 445, and the top side of the second mixing chamber 446 is conductively connected to the bottom end of the air collecting box 42, and the inner walls of the first mixing chamber 445 and the second mixing chamber 446 are arranged in a spiral shape, which is beneficial to prolong the mixing time of the hot air in the first mixing chamber 445 and the second mixing chamber 446, so that they are mixed evenly, and it is convenient for the subsequent evaporator 44 to quickly cool the hot air.

[0044] In this embodiment, considering that the hot air directly discharged from the hot air output pipe 3 into the air collecting box 42 has the characteristic of uneven heat, in order to fully utilize the cold energy generated by the evaporator 44, a mixing cylinder 443 is installed. After the hot air output pipe 3 outputs the cold air to the air collecting box 42, the hot air first enters the second mixing chamber 446 due to the isolation plate 444 dividing the mixing cylinder 443 into a first mixing chamber 445 and a second mixing chamber 446, and then enters the first mixing chamber 445 from the bottom of the second mixing chamber 446, so that the hot air is fully mixed in the first mixing chamber 445 and the second mixing chamber 446, and then discharged and then passed through the diverter 441 to enter the evaporator 44 for evaporative cooling. The temperature of the hot air entering the evaporator 44 is ensured to be uniform, so that the evaporator 44 has a better evaporative cooling effect on the hot air, avoids the problem of uneven local hot air cooling, and improves the cooling effect on the frequency conversion chamber 1.

[0045] To summarize, the present invention centrally distributes the cold air after cooling by the water source cooling unit by arranging an automatic conveying device, and detects the temperature of the upper and lower areas inside the frequency conversion room through a temperature measurement and adjustment component, so as to adjust the position of the electric push rod according to the upper and lower temperature differences, thereby adjusting the position of the isolation seat, so as to adjust the space size of the upper and lower air collecting chambers, so as to facilitate the output of cold air with different cooling amounts in the upper and lower areas according to the actual temperature difference, thereby realizing precise heat dissipation and cooling of different areas inside the frequency conversion room, effectively reducing the occurrence of uneven heat dissipation, and improving the heat dissipation efficiency; therefore, the present invention effectively overcomes the various shortcomings of the prior art and has a high industrial utilization value.

Anyone familiar with the art may modify or alter the above embodiments without departing from the spirit and scope of the present invention.
