Description

A heat dissipation system for fracturing equipment and fracturing equipment Technical Field

[0001] This utility model relates to the field of heat dissipation technology for fracturing equipment, specifically to a heat dissipation system for fracturing equipment and fracturing equipment. Background Technology

[0002] Fracturing equipment is relatively high-powered, and each piece of equipment requires a cooling system to maintain the temperature of the core components. Currently, plate-fin radiators are mainly used for heat exchange with the outside air to achieve heat dissipation. The well site environment is harsh; sand, sludge, gravel, and fracturing dust can settle on the radiator core. These impurities adhere to the surface of the plate-fin core, affecting ventilation and heat exchange, resulting in poor heat dissipation. High temperatures can easily damage components of the fracturing equipment (e.g., high temperatures in the lubricating medium lead to decreased lubrication performance, which in turn damages components such as the plunger pump), causing the equipment to shut down due to high temperatures. Furthermore, current fracturing equipment operates under continuous operation conditions, with long daily working hours and virtually no spare time for equipment maintenance, creating a vicious cycle of heat dissipation problems. If the equipment is shut down for radiator cleaning, the operating efficiency of the fracturing equipment will be reduced. Summary of the Invention

[0003] The present invention aims to at least solve the technical problems in the prior art, such as the poor heat dissipation performance of the heat dissipation system of fracturing equipment, which easily leads to damage to fracturing equipment components and abnormal shutdown of fracturing equipment, as well as reduced operating efficiency of fracturing equipment.

[0004] To solve the above-mentioned technical problems, this utility model provides a heat dissipation system for fracturing equipment, including a heat dissipation core. The heat dissipation core is installed on the upper platform of the fracturing equipment near the component to be cooled. The upper and / or lower part of the heat dissipation core is provided with a cleaning pipeline, and a cleaning nozzle is provided on the side of the cleaning pipeline facing the heat dissipation core.

[0005] In some embodiments, the cleaning nozzles are a plurality of nozzles spaced apart along the cleaning pipeline, and the spray ranges of two adjacent cleaning nozzles partially overlap.

[0006] In some embodiments, the cleaning conduit extends to the outside of the heat sink core.

[0007] In some embodiments, the heat dissipation system further includes a cleaning agent tank connected to the cleaning pipeline, the cleaning pipeline being provided with a quick-connect interface.

[0008] The cleaning agent tank is connected to a quick-connect interface at one end of the cleaning pipeline via a pumping device, and a first control valve is provided on the first cleaning agent pipeline between the outlet of the pumping device and the cleaning pipeline; or

[0009] The heat dissipation system also includes a pressure tank, which is connected to the inlet of the cleaning agent tank via a first gas pipeline, and the outlet of the cleaning agent tank is connected to the quick-connect interface of the cleaning pipeline via a second cleaning agent pipeline. The first gas pipeline is equipped with a second control valve, and the second cleaning agent pipeline is equipped with a third control valve. Alternatively, the pressure tank is connected to the quick-connect interface at one end of the cleaning pipeline via a second gas pipeline, the cleaning agent tank is located above the cleaning pipeline and is connected to the cleaning pipeline via a third cleaning agent pipeline, the second gas pipeline is equipped with a fourth control valve, and the third cleaning agent pipeline is equipped with a fifth control valve.

[0010] In some embodiments, the cleaning agent tank is mounted on the superstructure platform or outside the superstructure platform.

[0011] In some embodiments, the heat dissipation system further includes a heat dissipation fan disposed on the upper part of the heat dissipation core, wherein the airflow direction of the heat dissipation fan is in the same direction as the jet direction of the cleaning nozzle.

[0012] In some embodiments, the heat dissipation fins of the heat dissipation core have a corrugated structure.

[0013] In some embodiments, the distance between two adjacent heat dissipation fins is greater than or equal to 4 mm.

[0014] In some embodiments, the heat dissipation system further includes a controller connected to the cleaning nozzle.

[0015] The cleaning pipeline is disposed at the upper and lower parts of the heat dissipation core. The heat dissipation system also includes a differential pressure sensor for detecting the pressure difference between the upper and lower parts of the heat dissipation core, and the differential pressure sensor is connected to the controller; or

[0016] The cleaning pipeline is located at the upper or lower part of the heat dissipation core, and the heat dissipation system also includes a pressure sensor for detecting the upper or lower pressure of the heat dissipation core, the pressure sensor being connected to the controller.

[0017] This utility model also provides a fracturing device including the above-mentioned heat dissipation system.

[0018] The heat dissipation system of this utility model embodiment for fracturing equipment, and the fracturing equipment itself, involves setting cleaning pipelines at the upper and / or lower parts of the heat dissipation core, and setting cleaning nozzles on the side of the cleaning pipelines facing the heat dissipation core. The heat dissipation core and the cleaning pipelines are installed on the upper platform of the fracturing equipment near the components to be cooled. High-pressure cleaning agent sprayed from the cleaning nozzles cleans impurities on the surface of the heat dissipation core or in the gaps between the heat dissipation plates, reducing the accumulation of impurities on the core surface or in the gaps between the plates. This prevents impurities from covering the heat dissipation core surface and causing a decrease in heat dissipation performance, thus improving the heat dissipation performance of the heat dissipation core. This effectively cools the heat dissipation components on the fracturing equipment, preventing a decrease in lubrication performance due to high temperatures of the lubricating medium, reducing abnormal shutdowns caused by damage to fracturing components, and ensuring the normal, continuous, and reliable operation of the fracturing equipment. Simultaneously, the flow of cleaning agent within the cleaning pipelines further enhances the cooling efficiency of the heat dissipation core, improving its heat dissipation performance. Furthermore, the above-mentioned heat dissipation system can reduce the frequency of downtime maintenance, ensuring the working efficiency of the fracturing equipment. Attached Figure Description

Therefore, the above description should not be considered as limiting, but merely as an example of embodiments. Other modifications within the scope and spirit of this invention will be apparent to those skilled in the art.

[0033] The accompanying drawings, which are included in and form part of this specification, illustrate embodiments of the present invention and, together with the general description of the present invention given above and the detailed description of the embodiments given below, serve to explain the principles of the present invention.

Therefore, the specific structural and functional details claimed herein are not intended to be limiting, but merely to serve as the basis and representative basis for the claims to teach those skilled in the art to use the present invention in a variety of substantially any suitable detailed structures.

[0038] This specification may use the phrases “in one embodiment,” “in another embodiment,” “in yet another embodiment,” or “in other embodiments,” all of which may refer to one or more of the same or different embodiments according to the present invention.

[0039] The fins of conventional radiators used in existing fracturing equipment typically have a fin gap of 2mm, allowing sand and small particles to become trapped between the fins during outdoor use. These radiators consist only of a frame, plate-fin radiators, and cooling medium circulation pipes, lacking self-cleaning capabilities. In continuous operation of fracturing equipment, with long daily working hours, stopping the machine for radiator cleaning would reduce production efficiency. In hot weather, the high outdoor air temperature reduces air-cooling efficiency; furthermore, there is no additional cooling medium to contribute to heat dissipation.

[0040] Figures 1 to 8 show schematic diagrams of the heat dissipation system of the fracturing equipment provided in the embodiments of the present invention. As shown in Figures 1 to 8, the embodiments of the present invention provide a heat dissipation system for fracturing equipment, including a heat dissipation core 1. The heat dissipation core 1 is installed on the upper platform 20 of the fracturing equipment near the component to be cooled. The upper and / or lower parts of the heat dissipation core 1 are provided with cleaning pipes 2, and the side of the cleaning pipes 2 facing the heat dissipation core 1 is provided with cleaning nozzles 3.

[0041] Fracturing equipment includes components such as plunger pumps, mixing systems, drive systems, and fracturing manifolds. Plunger pumps are used in environments requiring high-pressure pumping; for example, they can pump cement slurry mixed by the mixing system to oilfields onshore or in desert areas for cementing operations. The sand mixing system is used to mix, stir, and transport the sand and other media required for fracturing operations; it is a key component in oil and gas field fracturing reservoir stimulation, sand control, and acidizing operations. The drive system powers the plunger pump and mixing system; it can be a hydraulic or electric drive system. The fracturing manifold (e.g., a high-pressure manifold) is a surface device connecting the surface pipeline to the plunger pump, used to collect the fluid pumped by the plunger pump and inject it into the target formation of the fracturing well.

[0042] The upper structure platform 20 of the fracturing equipment refers to the transport platform of the fracturing equipment. The upper structure platform 20 includes, but is not limited to, semi-trailer trailers, multi-axle drive off-road chassis vehicles, skid-mounted equipment, fixed platforms, and other structures. As shown in Figure 7, the upper structure platform 20 is a semi-trailer trailer 201, and the plunger pump 301 and the main motor 302 that drives the plunger pump 301 are mounted on the semi-trailer trailer 201; as shown in Figure 8, the upper structure platform 20 is a skid-mounted equipment 202, and the plunger pump 301 and the main motor 302 that drives the plunger pump 301 are mounted on the skid-mounted equipment 202.

[0043] The cooling system is located on the upper platform 20 of the fracturing equipment, near the components requiring cooling. These components include the aforementioned plunger pump, mixing system, and drive system. As shown in Figures 7 and 8, the cooling assembly 40, consisting of the cooling core 1 and cleaning pipes 2, is positioned on the upper platform 20 between the plunger pump 301 and the main motor 302, allowing simultaneous cooling of both. The cooling assembly 40 can be mounted on the upper platform 20 using mounting brackets 50. The plunger pump 301 typically requires a lubricating medium (e.g., lubricating oil) to reduce friction and wear between moving parts (e.g., plunger and cylinder walls). Excessive lubricating medium temperature reduces lubrication performance, leading to damage to moving parts. Therefore, timely cooling through the cooling system is necessary to prevent damage to the plunger pump 301. The main motor 302 generates significant heat during operation due to mechanical and electrical losses; therefore, timely cooling through the cooling system is also required to prevent motor damage. Since it generates even more heat, the cooling assembly 40 can be positioned close to the main motor 302.

[0044] As shown in Figure 1, the heat dissipation assembly 40 also includes a heat dissipation frame 60. The heat dissipation core 1 is mounted on the heat dissipation frame 60. The cleaning pipe 2 is installed laterally on the heat dissipation frame 60 along the length and / or width of the heat dissipation core 1, so that the cleaning pipe 2 is arranged laterally above or below the heat dissipation core 1. The cleaning pipe 2 contains a cleaning agent, which can be sprayed towards the heat dissipation core 1 through the cleaning nozzle 3. The sprayed cleaning agent is a high-pressure cleaning agent, which can self-clean impurities on the surface of the heat dissipation core 1 or in the gaps between the heat dissipation plates, reduce the accumulation of impurities on the surface of the core or in the gaps between the plates, avoid impurities covering the surface of the heat dissipation core 1 and causing a decrease in heat dissipation performance, improve the heat dissipation performance of the heat dissipation core 1, effectively cool the heat dissipation components that need to dissipate heat on the fracturing equipment, avoid the decrease in lubrication performance caused by high temperature of the lubricating medium, reduce abnormal shutdowns caused by damage to fracturing equipment components, and ensure the normal, continuous and reliable operation of the fracturing equipment. The above heat dissipation system can reduce the frequency of shutdown maintenance and ensure the working efficiency of the fracturing equipment. Meanwhile, the flow of the cleaning agent within the cleaning pipe 2 further enhances the cooling efficiency of the heat sink 1, improving its heat dissipation performance. The cleaning agent can be a liquid or a gas. For example, if the cleaning agent is room temperature water, the water flowing over the surface of the heat sink 1 and sprayed from the cleaning nozzle 3 at that location cleans the heat sink 1, removing some impurities and heat, thus improving the cooling effect on the surface of the heat sink 1. Alternatively, if the cleaning agent is air, the airflow effectively increases the flow area, thereby increasing the heat dissipation efficiency of the heat sink 1 surface.

[0045] It is understood that in this embodiment, the heat dissipation core 1, cleaning pipe 2, and other components of the heat dissipation system are integrated into a single heat dissipation assembly 40 via the heat dissipation frame 60, facilitating the installation of the heat dissipation core 1 and cleaning pipe 2 on the upper platform 20. Alternatively, the heat dissipation core 1 and cleaning pipe 2 can be arranged separately (i.e., the heat dissipation frame 20 can be omitted, and the heat dissipation core 1 and cleaning pipe 2 can be arranged near the component to be cooled using mounting brackets, snap-fit ​​components, etc.), which can reduce the processing cost of the heat dissipation assembly 40 and allows for flexible arrangement of the heat dissipation core 1 and cleaning pipe 2. For example, the height between the cleaning pipe 2 and the heat dissipation core 1 can be adjusted arbitrarily as needed. However, after the heat dissipation core 1 and cleaning pipe 2 are integrated via the heat dissipation frame 60, the height between them is limited by the dimensions of the heat dissipation frame 60. As shown in Figure 7, in this embodiment, the heat dissipation assembly 40 can also be an inverter radiator, installed in the electrical room 70 (E-house) of the fracturing equipment to effectively dissipate heat from the electrical room 70.

[0046] In some embodiments, the cleaning nozzles 3 are multiple nozzles spaced apart along the cleaning conduit 2, with the spray ranges of adjacent nozzles 3 partially overlapping. This ensures that the cleaning range of the cleaning nozzles 3 can cover the entire surface of the heat sink core 1, guaranteeing a cleaning effect.

[0047] The cleaning nozzle 3 can spray cleaning agent at a wide angle to clean the heat sink core 1; the angle range of the cleaning nozzle 3 can be adjusted to adjust the spray direction and spray range of the cleaning nozzle 3; the spray flow rate of the cleaning nozzle 3 can also be adjusted, thereby achieving multi-angle, multi-coverage and multi-flow control cleaning of the surface of the heat sink core 1, improving cleaning efficiency and cleaning effect, and saving energy and protecting the environment.

[0048] In some embodiments, the cleaning nozzle 3 is connected to the cleaning pipeline 2 via a threaded or quick-connect fitting, facilitating quick assembly and disassembly of the cleaning nozzle 3.

[0049] Cleaning pipeline 2 can be an integrated pipeline structure to ensure the flow of cleaning agent and prevent cleaning agent leakage; cleaning pipeline 2 can also be a multi-section pipeline, with two adjacent pipeline sections connected by quick connectors, which is convenient for disassembly and assembly, and can be replaced in time when some pipeline sections are damaged, reducing pipeline costs.

[0050] In some embodiments, the cleaning conduit 2 extends to the outside of the heat dissipation core 1 to ensure that the spray range of the cleaning nozzle 3 can cover the entire heat dissipation core 1.

[0051] In some embodiments, the heat dissipation system further includes a cleaning agent tank 41 connected to the cleaning pipeline 2, and the cleaning pipeline 2 is provided with a quick-connect interface 21. The quick-connect interface 21 is used to connect a quick-connect fitting, so that the cleaning agent tank 41 and the cleaning pipeline 2 can be quickly and conveniently connected through the quick-connect fitting and the cleaning agent pipeline 80.

[0052] In this embodiment, the cleaning agent tank 41 serves as a liquid supply device. One end of the cleaning pipeline 2 has a quick-connect interface 21 connected to the cleaning agent tank 41 via a first quick-connect fitting and the cleaning agent pipeline 80. The other end of the cleaning pipeline 2 also has a quick-connect interface 21, which connects to the return tank via a second quick-connect fitting and the cleaning agent pipeline 80, enabling the recycling of the cleaning agent. The quick-connect fitting can be placed on the upper platform 20 of the fracturing equipment for easy connection. The quick-connect interface 21 can be located at either end of the cleaning pipeline 2 or on the pipe wall of the cleaning pipeline 2; its specific location is not specifically limited in this embodiment.

[0053] In some embodiments, as shown in Figures 2 and 3, the cleaning agent tank 41 is connected to a quick-connect interface 21 at one end of the cleaning pipeline 2 via a pumping device 5, and a first control valve 61 is provided on the first cleaning agent pipeline 801 between the outlet of the pumping device 5 and the cleaning pipeline 2.

[0054] The outlet of the pumping device 5 is connected to the cleaning pipeline 2 via a first cleaning agent pipeline 801. When the cleaning agent is liquid, it can be transported from the cleaning agent tank 41 to the cleaning pipeline 2 via the pumping device 5. The pumping device 5 includes, but is not limited to, gear pumps, vane pumps, plunger pumps, pneumatic pumps, etc., which can quickly and reliably draw and pump the cleaning agent from the cleaning agent tank 41. Optionally, the pumping device 5 is equipped with a filtration system to ensure the cleanliness of the cleaning agent.

[0055] The first control valve 61 is located on the first cleaning agent pipeline 801 near the outlet of the pumping device 5. It can precisely control the flow rate of the cleaning agent entering the first cleaning agent pipeline 801, and thus control the flow rate of the cleaning agent entering the cleaning pipeline 2.

[0056] In other embodiments, as shown in FIG4, the heat dissipation system further includes a pressure tank 42, which is connected to the inlet of the cleaning agent tank 41 via a first gas pipeline 901. The outlet of the cleaning agent tank 41 is connected to the quick-connect interface 21 of the cleaning pipeline 2 via a second cleaning agent pipeline 802. A second control valve 62 is provided on the first gas pipeline 901 between the pressure tank 42 and the inlet of the cleaning agent tank 41, and a third control valve 63 is provided on the second cleaning agent pipeline 802 between the outlet of the cleaning agent tank 41 and the cleaning pipeline 2.

[0057] In this embodiment, the cleaning agent can also be delivered using a pneumatic delivery method. The inlet of the cleaning agent tank 41 is located at the top of the tank, and the outlet is located at the bottom. The inlet of the cleaning agent tank 41 is connected to the pressure tank 42. A second control valve 62 is installed on the connecting pipeline (first gas pipeline 901) between the two. A third control valve 63 is installed on the second cleaning agent pipeline 802 between the outlet of the cleaning agent tank 41 and the cleaning pipeline 2. When cleaning agent needs to be supplied to the cleaning pipeline 2, the second control valve 62 and the third control valve 63 are opened, and air pressure is transmitted into the cleaning agent tank 41. The air pressure pushes the cleaning agent out and delivers it to the cleaning nozzle 3 through the cleaning pipeline 2 for heat dissipation and cleaning. In this embodiment, by placing the inlet of the cleaning agent tank 41 at the top and the outlet at the bottom, the positive pressure gas entering from the top can compress the cleaning agent, effectively pushing it out.

[0058] In some embodiments, as shown in Figure 5, the pressure tank 42 is connected to the quick-connect interface 21 at one end of the cleaning pipeline 2 via a second gas pipeline 902. The cleaning agent tank 41 is located above the cleaning pipeline 2 and is connected to the cleaning pipeline 2 via a third cleaning agent pipeline 803. A fourth control valve 64 is provided on the second gas pipeline 902 between the pressure tank 42 and the cleaning pipeline 2, and a fifth control valve 65 is provided on the third cleaning agent pipeline 803 between the cleaning agent tank 41 and the cleaning pipeline 2. In this embodiment, the cleaning agent tank 41 and the pressure tank 42 are respectively connected to the cleaning pipeline 2. The cleaning agent tank 41 is located above the cleaning pipeline 2, and can utilize the gravity flow of the cleaning agent or the Venturi principle to mix the high-speed flowing high-pressure gas discharged with the pressure tank 42 and then deliver the cleaning agent to the cleaning nozzle 3 through the cleaning pipeline 2.

[0059] In the above embodiments, the cleaning agent is a liquid, which can be directly pumped to the cleaning pipeline 2 through the pumping device 5, or it can be transported to the cleaning nozzle 3 in the cleaning pipeline 2 by using the gas in the pressure tank 42.

[0060] In other embodiments, as shown in Figure 6, when the cleaning agent is a gas, the cleaning agent tank 41 is a pressure tank. The cleaning agent tank 41 is connected to the cleaning pipeline 2 through a third gas pipeline 903, and a sixth control valve 66 is provided on the third gas pipeline 903. In this embodiment, the gas can be directly delivered to the cleaning pipeline 2 through the sixth control valve 66, and then delivered to the cleaning nozzle 3, so as to clean the heat dissipation core 1 using the cleaning gas.

[0061] The aforementioned control valves can be controlled manually, pneumatically, electrically, or hydraulically. For example, ball valves, butterfly valves, and plug valves can be manually controlled to adjust the opening degree and control the delivery rate of cleaning agents. Operators can adjust the valves according to the working conditions, and the valves can be marked with information such as "off," "on," and angle scales for easy operation. In practice, hydraulic or electric valve actuators can also be used, with the control system automatically adjusting the valve opening degree.

[0062] In some embodiments, as shown in Figures 2 and 8, the cleaning agent tank 41 can be mounted on the upper platform 20. The cleaning agent is drawn from the cleaning agent tank 41 by a pumping device 5 (gear pump, vane pump, pneumatic pump, etc.), and transported to the cleaning pipeline 2 through the first cleaning agent pipeline 801, and then to the cleaning nozzle 3. As shown in Figures 3 and 7, the cleaning agent tank 41 may not be mounted on the upper platform 20. For example, it can be mounted on the well site ground. The specific location is not specifically limited by this invention.

[0063] In some embodiments, the heat dissipation system further includes a cooling fan 71 disposed on the upper part of the heat dissipation core 1. The airflow direction of the cooling fan 71 is the same as the jet direction of the cleaning nozzle 3, which helps the cleaning agent or airflow to circulate and improves the cleaning effect. The cooling fan 71 is connected to a cooling motor 72 for controlling the cooling fan 71. The cooling fan 71 is integrated and mounted on the heat dissipation frame 60, and is integrated with the heat dissipation core 1 and the cleaning pipeline 2 to form a heat dissipation assembly 40. The cooling fan 71 can also be installed separately. For example, when the heat dissipation core 1 and the cleaning pipeline 2 are located in the electrical room 70, the cooling fan 71 can be installed at the top inside the electrical room 70, above the heat dissipation core 1.

[0064] In some embodiments, the heat dissipation fins of the heat dissipation core 1 have a corrugated structure.

[0065] The corrugated structure can increase the gap between the heat dissipation fins, and the gap is continuous from top to bottom, which can increase the ventilation efficiency of the heat dissipation core 1, reduce dust accumulation, increase the passage of sand and dust, and reduce the problem of particulate matter blockage.

[0066] In some embodiments, the distance between two adjacent heat dissipation fins is greater than or equal to 4 mm.

[0067] The gap between the fins of a typical radiator is about 2mm. When used outdoors, sand or small sand particles can get stuck between the fins. In this embodiment, the gap between two adjacent fins is set to be greater than or equal to 4mm, for example, 5mm. This is more suitable for the windy and sandy conditions in oil fields. Small sand particles blown by the wind can pass through the gaps between the radiator cores without causing blockage.

[0068] In some embodiments, the heat dissipation system further includes a controller connected to the cleaning nozzle 3.

[0069] The cleaning pipeline 2 is disposed at the upper and lower parts of the heat dissipation core 1. The heat dissipation system also includes a differential pressure sensor 8 for detecting the pressure difference between the upper and lower parts of the heat dissipation core 1. The differential pressure sensor 8 is connected to the controller.

[0070] The differential pressure sensor 8 can communicate with the controller via wired or wireless means. The sensor effectively detects the pressure difference between the upper and lower sides of the heat sink core 1, and determines whether the heat sink system needs to be activated to clean the core 1 based on this pressure difference. If the detected pressure difference reaches the preset activation condition of the heat sink system, the controller controls the aforementioned control valves, cleaning nozzles 3, and other actuators to start working according to the preset control logic to clean the heat sink core 1. The controller can be a local controller for the fracturing equipment or a remote control system. The pressure difference detected by the differential pressure sensor 8 can be displayed in real time on the control terminal of the fracturing equipment or the remote control system.

[0071] The specific control logic of the controller is as follows:

[0072] 1) When the detected pressure difference value is greater than the preset heat dissipation system start pressure, the controller will trigger an alarm and control the heat dissipation system to start. The control valves of the heat dissipation system pipeline will be executed according to the preset position status. The cleaning agent will be delivered to the cleaning nozzle 3 through the cleaning agent tank 41, pipeline, valve and other components to clean the heat dissipation core 1.

[0073] 2) The controller can also receive the valve status of each control valve in real time, control the flow of cleaning agent, or determine whether each control valve is in a normal state.

[0074] For example, the controller can control the flow rate of cleaning agent entering the cleaning pipeline 2 based on the valve opening degree of each control valve. As another example, based on the differential pressure data fed back by the differential pressure sensor 8, the controller determines that the first control valve 61 should be in the open state. At this time, the controller can obtain the status of the first control valve 61 through the valve position sensor located at the position of the first control valve 61. If the valve position sensor indicates that the first control valve 61 is in the closed state, it is determined that the first control valve 61 may be faulty, and the controller will trigger a valve status abnormality alarm, prompting the operator to promptly investigate and resolve the fault.

[0075] In other embodiments, the cleaning pipe 2 is disposed at the upper or lower part of the heat dissipation core 1, and the heat dissipation system further includes a pressure sensor for detecting the upper or lower pressure of the heat dissipation core 1, the pressure sensor being connected to the controller.

[0076] The differential pressure sensor 8 is used to detect the pressure on the upper and lower sides of the heat sink core 1. In some other embodiments, when the cleaning pipe 2 is only provided on the upper or lower part of the heat sink core 1, a pressure sensor can be provided on the upper or lower part of the heat sink core 1 according to the arrangement position of the cleaning pipe 2 to detect the pressure on the surface of the heat sink core 1 near the cleaning pipe 2, and the accumulation of impurities can be judged based on the pressure.

[0077] It is understandable that a differential pressure sensor can also be installed when the cleaning pipe 2 is located at the upper or lower part of the heat dissipation core 1.

[0078] In some embodiments, as shown in FIG1, the heat dissipation system further includes a liquid storage tank 43, which is disposed between the inlet of the cleaning pipeline 2 and the cleaning agent tank 41 to buffer the cleaning agent entering the cleaning pipeline 2, ensuring continuous and uniform spraying of the subsequent cleaning nozzles 3, and improving cleaning uniformity and cleaning effect, etc.

[0079] This utility model also provides a fracturing device including the above-described heat dissipation system. The heat dissipation system of the fracturing device corresponds to that of the fracturing device in the above embodiments.
