[0040] First embodiment:

[0041] Please refer to Figures 1 to 4 The present embodiment provides a fracturing equipment 10 applied to the exploration and development field of shale gas and deep well / super deep well. The fracturing equipment 10 can improve the technical problems of large volume and complex heat dissipation system structure of the fracturing device in the prior art.

[0042] In the present embodiment, the fracturing equipment 10 comprises a box body 100, a voltage conversion module 300, a first air cooling assembly 400 and two frequency converters 200. The box body 100 is provided with a first installation space 110 and a second installation space 120, and the second installation space 120 is adjacent to the first installation space 110 in the first direction. Optionally, the box body 100 is generally a container, of course, other box bodies 100 can also be used in other embodiments, which are not limited herein. Generally, the above-mentioned first direction generally refers to the length direction of the container. The two frequency converters 200 are arranged in the first installation space 110 along the second direction, and the two frequency converters 200 are spaced apart and form an air duct therebetween; the second direction is perpendicular to the first direction. Generally, the second direction generally refers to the width direction of the container. The voltage conversion module 300 is arranged in the second installation space 120; the voltage conversion module 300 is electrically connected with the two frequency converters 200. The first air cooling assembly 400 is arranged at the top of the first installation space 110, and is used to extract the airflow in the air duct and discharge it to the outside of the box body 100.

[0043] During the operation of the fracturing equipment 10, the first air cooling assembly 400 extracts and discharges the airflow in the air duct, at the same time, forms a negative pressure in the air duct, so that the external airflow can be sucked into the air duct; and the sucked airflow flows through the frequency converter 200 to achieve the effect of providing heat dissipation and cooling for the frequency converter 200. Since the external cold airflow directly passes through the frequency converter 200 to achieve cooling and heat dissipation of the frequency converter 200, the cooling effect of the frequency converter 200 can be improved. In addition, since the two frequency converters 200 are arranged in the second direction, the space occupied by the frequency converter 200 in the first direction can be reduced, so that the overall length of the box body 100 in the first direction can be shortened, thereby reducing the overall space occupied by the fracturing equipment 10, and facilitating the arrangement of the fracturing equipment 10. Among them, Figure 3 The arrow in the above formula indicates the direction of the airflow.

[0044] As described above, in the fracturing device 10, two frequency converters 200 are arranged in the first mounting space 110 along the second direction, the occupied space is saved in the first direction, the overall length of the fracturing device 10 is reduced, and the overall occupied space of the fracturing device 10 is reduced. At the same time, the air duct is formed between the two frequency converters 200, and the first air cooling assembly 400 is arranged above the air duct. The first air cooling assembly 400 can extract the airflow in the air duct, so that the external cold airflow can directly pass through the frequency converter 200 from the outside into the air duct, and the frequency converter 200 can have good heat dissipation effect. The structure of the first air cooling assembly 400 is simple, easy to operate, and low in implementation cost. Based on this, the fracturing device 10 can improve the technical problems such as large size and complex heat dissipation system structure of the fracturing device in the prior art.

[0045] Further, the first mounting space 110 is provided with a first partition plate 111, the first partition plate 111 is arranged at the top of the frequency converter 200, and the top of the first partition plate 111 forms a first air outlet passage; the first air cooling assembly 400 is arranged in the first air outlet passage and is used for air outlet from the first air outlet passage; and the box body 100 is provided with a louver corresponding to the first air outlet passage. The purpose of arranging the first partition plate 111 is to divide the first mounting space 110 into two mutually separated spaces, so as to avoid airflow short circuit caused by air inlet and air outlet confusion. That is, the flow path of the cold airflow entering from the front of the frequency converter 200 is strictly separated from the flow path of the first air cooling assembly 400 air outlet from the first air outlet passage, which is beneficial to the orderly flow of the airflow and ensures that the frequency converter 200 has high-efficiency heat dissipation and cooling effect.

[0046] It is worth noting that, generally, in order to save materials, the first partition plate 111 can be arranged only at the top of the frequency converter 200 near the front edge, and the gap formed between the top of the front side of the frequency converter 200 and the box body 100 can be closed to avoid air inlet and air outlet confusion. At this time, part of the inner wall of the first air outlet passage is formed by the top of the frequency converter 200. Of course, in other embodiments, the first partition plate 111 can be laid on the top of the frequency converter 200, so that the first partition plate 111 blocks part or the entire top of the frequency converter 200. The first partition plate 111 can effectively separate the air inlet area and the air outlet area, ensure the smooth flow of the airflow, and further ensure the effective heat dissipation and cooling of the frequency converter 200.

[0047] In addition, it should be noted that the first air cooling assembly 400 is arranged in the area above the first partition plate 111, and the first air cooling assembly 400 is arranged corresponding to the air duct, so that the first air cooling assembly 400 can extract the air in the air duct.

[0048] Further, in the embodiment, the first air cooling assembly 400 includes a plurality of air fans which are independently arranged on the top of the air duct. The plurality of air fans are not only independent of each other, but also decoupled from the frequency converter 200. In other words, the plurality of air fans are also independent of the frequency converter 200. On the one hand, the number of air fans can be configured according to actual needs to meet actual needs. On the other hand, the first air cooling assembly 400 can be easily maintained and replaced.

[0049] In the embodiment, the cabinet 100 is provided with first cabinet doors 112 on both sides in the second direction. The two first cabinet doors 112 are arranged corresponding to the first installation space 110 and are used to open or close the first installation space 110. The first cabinet doors 112 are provided with louvers. When the first cabinet doors 112 are opened, the corresponding frequency converter 200 is exposed, so that daily operation and maintenance can be performed. When the first cabinet doors 112 are closed, the frequency converter 200 is protected. The louvers on the first cabinet doors 112 can be used for air flow to achieve air inlet of the air duct. The two frequency converters 200 are arranged opposite to each other and face the two first cabinet doors 112, respectively.

[0050] In addition, it should be noted that the secondary wiring of the voltage transformation module 300 is led out from both sides of the voltage transformation module 300 and connected to the two frequency converters 200, respectively. The wiring positions are all towards the first cabinet doors 112 to facilitate construction and subsequent maintenance work. Only one phase-shifting transformer can be configured, and a double-sided secondary wiring mode is adopted to achieve the same functional effect as the traditional scheme of configuring two transformers. This design not only saves the material cost of the transformer, but also simplifies the structure of the cabinet 100 of the container transformer room, further shortens the size of the cabinet 100, and thus reduces the overall cost of the equipment.

[0051] In the embodiment, the voltage transformation module 300 is provided with a second air cooling assembly 310 arranged on the top. The second installation space 120 is further provided with a second partition plate or air duct 311, and the cabinet 100 is further provided with an air outlet corresponding to the second installation space 120. When the air duct 311 is arranged in the cabinet 100, one end of the air duct 311 is connected to the second air cooling assembly 310, and the other end of the air duct 311 is connected to the air outlet to discharge air from the air outlet. Or, when the second partition plate is arranged in the cabinet 100, the second partition plate is arranged on the top of the voltage transformation module 300 and a second air outlet channel is formed on the top of the second partition plate. The second air outlet channel is connected to the air outlet to discharge air from the air outlet.

[0052] It is worth mentioning that the second air cooling assembly 310 can be regarded as a self-contained heat dissipation structure of the variable voltage module 300. By arranging the air duct 311 or the second partition plate, the air inlet area and the air outlet area of the second mounting space 120 can be separated, thereby avoiding confusion between the air inlet and the air outlet, ensuring smooth air inlet and smooth air outlet, and ensuring the heat dissipation and cooling effect of the variable voltage module 300. When the air duct 311 or the second partition plate is arranged, the air duct 311 or the second partition plate is directly connected to the air outlet of the second air cooling assembly 310, so as to effectively separate the air inlet and outlet areas.

[0053] In the embodiment, the box body 100 further comprises a third mounting space 130 and a fourth mounting space 140, and the third mounting space 130 and the fourth mounting space 140 are arranged at two ends of the box body 100 along the first direction. In addition, the fracturing equipment 10 further comprises a control module 500 and a power distribution module 600; the control module 500 is arranged in the third mounting space 130, and the variable voltage module 300 and the two frequency converters 200 are electrically connected to the control module 500; the power distribution module 600 is arranged in the fourth mounting space 140, and the variable voltage module 300 and the two frequency converters 200 are electrically connected to the power distribution module 600. That is, the power distribution module 600 and the control module 500 are arranged at two ends of the box body 100, respectively, so that the high-voltage and low-voltage areas can be isolated, the cross connection of high-voltage and low-voltage wiring can be reduced, and the mass load distribution of the container can be balanced. Preferably, the power distribution module 600 is arranged adjacent to the variable voltage module 300, and the control module 500 is arranged adjacent to the frequency converter 200; that is, the third mounting space 130 is arranged adjacent to the first mounting space 110, and the fourth mounting space 140 is arranged adjacent to the second mounting space 120, so as to shorten the wiring distance of the power distribution cable.

[0054] In order to facilitate operation, the third mounting space 130 is provided with a second cabinet door 131 on the end surface along the first direction, and the second cabinet door 131 is used to open or close the third mounting space 130. Similarly, the fourth mounting space 140 is provided with a third cabinet door 141 at one end along the first direction, and the third cabinet door 141 is used to open or close the fourth mounting space 140. In addition, an interface can be reserved on the second cabinet door 131 to facilitate the optional industrial air conditioner in the application environment.

[0055] In summary, in the fracturing equipment 10 provided in the embodiment, two frequency converters 200 are arranged in the first installation space 110 along the second direction, the occupied space is saved in the first direction, the overall length of the fracturing equipment 10 is reduced, and then the overall occupied space of the fracturing equipment 10 can be reduced. At the same time, the air duct is formed between the two frequency converters 200, and the first air cooling assembly 400 is arranged above the air duct. The first air cooling assembly 400 can extract the airflow in the air duct, so that the external cold airflow can directly pass through the frequency converter 200 from the outside into the air duct, and the frequency converter 200 can have good heat dissipation effect. The structure of the first air cooling assembly 400 is simple, easy to operate, and has low implementation cost. Based on this, the fracturing equipment 10 can improve the technical problems such as large volume and complex structure of the heat dissipation system of the fracturing device in the prior art. Further, the first cabinet door 112 is formed on both sides of the first installation space 110 along the second direction, and the first installation space 110 can be opened through the first cabinet door 112. At the same time, the second cabinet door 131 is formed on the end face of the third installation space 130, and the third cabinet door 141 is formed on one end of the fourth installation space 140 along the first direction, which can greatly facilitate the daily maintenance and operation of the equipment. The first installation space 110 adopts the design concept of two frequency converters 200 back-to-back sharing the air duct, which efficiently utilizes the overall space and expands a more spacious heat channel exhaust space for the frequency converter 200 room, effectively reducing the system air resistance. In addition, the back-to-back structure of the two frequency converters 200 enables the frequency converter 200 to realize double-sided synchronous air intake, further reducing the system air resistance. Further, the back-to-back air duct design of the two frequency converters 200 also promotes the full mixing of hot air, effectively reducing the overall temperature gradient of the first installation space 110. Even in the state of unbalanced double-drive load, the container can still maintain uniform temperature field distribution, thereby greatly reducing the risk of condensation phenomenon in the first installation space 110 in the box 100, and ensuring the stable operation of the equipment.

[0056] Second embodiment:

[0057] Please refer to Figure 5 In the embodiment, a fracturing equipment 10 is provided, which can also improve the technical problems such as large volume and complex structure of the heat dissipation system of the fracturing device in the prior art.

[0058] The difference between the fracturing equipment 10 provided in the embodiment and the fracturing equipment 10 provided in the first embodiment is that two second installation spaces 120 are arranged in the box body 100 in the fracturing equipment 10 in the embodiment, and the two second installation spaces 120 are arranged on the two sides of the first installation space 110 along the first direction respectively; and the two second installation spaces 120 are each provided with a voltage transformation module 300. The voltage transformation modules 300 in the two second installation spaces 120 are symmetrically arranged relative to the first installation space 110.

[0059] In addition, the parts not mentioned in the embodiment can refer to the setting form in the first embodiment.

[0060] The symmetric arrangement of the two voltage transformation modules 300 relative to the first installation space 110 is beneficial to the centering of the overall center of gravity of the fracturing equipment 10, and is more beneficial to transportation in a poor road condition station environment, can cope with poor handling operation conditions in industrial or outdoor environments, and is safer for transportation and handling.

[0061] Third embodiment:

[0062] Please refer to Figure 6 The fracturing equipment 10 provided in the embodiment can also improve the technical problems of large volume and complex heat dissipation system structure of the fracturing device in the prior art.

[0063] The difference between the fracturing equipment 10 provided in the embodiment and the fracturing equipment 10 provided in the first embodiment is that in the first embodiment, the voltage transformation module 300 refers to one transformer arranged in the second installation space 120; while in the embodiment, the voltage transformation module 300 includes two transformers, and the two transformers are symmetrically arranged in the second installation space 120 along the second direction. Further, the secondary wiring positions of the two transformers are both towards the opening direction of the two sides of the container. And the two transformers share the channel steel chassis of the box body 100.

[0064] In addition, the parts not mentioned in the embodiment can refer to the setting form in the first embodiment.

[0065] In the embodiment, the two transformers arranged in the second installation space 120 adopt a symmetric centralized arrangement mode, and only the air inlet and outlet of the isolation transformer need to be specially handled, which effectively avoids the complicated partition design of the container, and further compresses the production cost of the container from the root. And arranging the heavy frequency converter 200 and the transformer close to the center position of the square container can center the overall center of gravity of the fracturing equipment 10, which can facilitate transportation, and even in a complex and poor road condition station transportation environment, it can also cope with various poor handling operation conditions, which is beneficial to the safety of the transportation and handling process.
