Description

A fracturing truck with a heat dissipation system Technical Field

[0001] This invention relates to the field of fracturing truck heat dissipation technology, and in particular to a fracturing truck equipped with a heat dissipation system. Background Technology

[0002] Modern fracturing trucks must be equipped with cooling systems to dissipate heat from the fracturing equipment. However, traditional fracturing truck cooling systems, due to their flawed design, are prone to re-drawing in hot air exhausted from the equipment on a single truck or between multiple trucks, resulting in poor heat dissipation. Furthermore, current cooling methods for large and medium-sized IC36 motors generally use independent fans for cooling, but the poor waterproofing and dustproofing of the fan inlets severely impacts motor lifespan; the high noise levels generated by the fans also seriously affect the health of personnel near the equipment.

[0003] Existing fracturing truck cooling systems, such as the self-elevating electric fracturing skid (patent number CN213331051U), include a base on which a fracturing pump, a variable frequency motor, and supporting equipment are integrated. A lifting device is also integrated on the base to raise the base to a loading / unloading height H. Compared to diesel engine-driven systems, electric drive systems use electricity instead of diesel, reducing operating costs, providing stable low-speed performance, and enabling stable maximum pressure output even with a small displacement engine. Furthermore, it produces less noise and is less likely to cause environmental pollution, meeting environmental protection requirements. This invention uses a variable frequency motor drive, achieving stepless adjustment of pressure and flow, zero emissions, energy saving, and environmental protection. It also features a built-in lifting component, eliminating the need for a crane during transport and relocation, significantly improving relocation and moving speed, saving production costs, and increasing production efficiency. While the disclosed cooling structure is for the fracturing pump, existing technology lacks details on how to avoid interference when cooling the various components of the entire fracturing truck. Summary of the Invention

[0004] The purpose of this invention is to provide a fracturing truck with a heat dissipation system, which solves the problems of how to avoid interference between the fracturing truck's own heat dissipation system and between multiple trucks.

[0005] This invention is implemented as follows: a fracturing truck with a heat dissipation system includes a fracturing pump system, a drive system, and an electrical control room. The drive system is controlled by the electrical control room to drive the fracturing pump system to perform fracturing operations. The fracturing truck also includes:

[0006] A first heat dissipation system is used to dissipate heat from the fracturing pump system. The air inlet of the first heat dissipation system faces downward and the air outlet faces upward. A lubricating oil pipe for circulating and carrying away heat from the fracturing pump system is provided between the air inlet and the air outlet of the first heat dissipation system.

[0007] The second cooling system is used to cool the drive system. The air inlet of the second cooling system faces downward and the air outlet faces the side of the fracturing vehicle.

[0008] The third heat dissipation system is used to dissipate heat from the electrical control room. The first air inlet of the third heat dissipation system is located on one side of the electrical control room, and the first air outlet of the third heat dissipation system is located on the other side of the electrical control room with its opening facing upward.

[0009] In this invention, the fracturing pump system dissipates heat through a first cooling system with its air inlet facing downwards and its air outlet facing upwards. The drive system dissipates heat using its internal air ducts and a second cooling system with its air inlet facing downwards. Cold air entering through the second cooling system passes through the air ducts inside the drive system and is discharged from the side of the drive system. The air ducts inside the electrical control room, in conjunction with a third cooling system, allow cold air to enter through the first air inlet of the electrical control room, pass through the internal air ducts of the electrical control room, and be discharged through the first air outlet of the electrical control room. It can be seen that the first, second, and third cooling systems fully utilize the structural features of the fracturing truck itself, ensuring that the heat dissipation of the equipment of a single fracturing truck does not interfere with each other. At the same time, considering the working conditions of multiple trucks arranged side by side at the fracturing site, the optimized design prevents the hot air discharged by the fracturing truck from being sucked into adjacent cooling systems, effectively improving the heat dissipation efficiency of single and multiple fracturing trucks.

[0010] A further technical solution of the present invention is: the third heat dissipation system includes a guide member placed on the first air outlet of the third heat dissipation system, the guide member being used to switch the airflow direction of the first air outlet of the third heat dissipation system to obliquely upward.

[0011] Cold air enters the electrical control room from the first air inlet on one side. The cold air carries away heat through the air duct of the electrical control room's own fan, forming hot air. The hot air is discharged upward from the first air outlet on the other side of the electrical control room under the action of the guide, thus preventing the fracturing trucks from being sucked in by adjacent fracturing trucks when multiple fracturing trucks are set up.

[0012] The electrical control room uses its own fan duct for air cooling. Hot air is blown directly upwards through the opening on the side and top, without affecting the air intake of other equipment.

[0013] A further technical solution of the present invention is: the guide member is a triangular prism, the top surface of the triangular prism is open, and the side surface of the triangular prism is open and connected to the first air outlet of the third heat dissipation system.

[0014] The adjacent quadrilateral faces of the triangular prism are open, and the hot air coming out of the electrical control room is discharged obliquely upward under the action of the guide, avoiding heat dissipation interference between adjacent fracturing trucks.

[0015] A further technical solution of the present invention is that the guide member can be moved into the electrical control room.

[0016] The guide is an openable and closable structure. When in use, it unfolds to guide and dissipate heat in the electrical control room. When not in use, it can be stored inside the electrical control room, thus not increasing the transport width.

[0017] A further technical solution of the present invention is: the third heat dissipation system further includes a second air inlet and a second air outlet, the second air inlet is located on one or both sides of the rear of the electrical control room, and the second air outlet is located at the rear end of the electrical control room.

[0018] To improve the heat dissipation of the electrical control room, a second air inlet is provided on the rear side and a second air outlet is provided at the rear end, which can dissipate the heat inside the rear of the electrical control room.

[0019] A further technical solution of the present invention is: the second heat dissipation system includes an air inlet shroud and a second heat dissipation system outlet. The air inlet shroud is arranged vertically, the air inlet of the second heat dissipation system is located at the bottom of the air inlet shroud, the air outlet of the air inlet shroud is located on the side of the air inlet shroud near the drive system and is connected to the drive system, and the air outlet of the second heat dissipation system is located on the side of the drive system for dissipating heat from the windings and bearings inside the drive system.

[0020] The drive system uses its own fan to draw in cool air from the air inlet of the air intake hood, and then blows it into the drive system through the air outlet of the air intake hood to remove heat. Hot air is discharged through the air outlet on the side of the drive system for air cooling. The fan used in the drive system has high air pressure, and hot air can be blown directly to the far sides of the fracturing truck without affecting the air intake of other equipment.

[0021] A further technical solution of the present invention is: the air inlet of the air inlet shroud is an inclined surface with the opening facing the drive system, the air inlet of the air inlet shroud is provided with a filter screen, and the inner wall of the air inlet shroud is provided with sound-absorbing cotton with a perforated plate.

[0022] The air inlet adopts an inclined structure, which can increase the air intake area and prevent rainwater from being blown into the air inlet by the wind. The air inlet uses a gas-liquid filter screen, which is composed of multiple layers of disordered metal wires. The capillary action of the metal wires can effectively capture water mist and dust in the air inlet.

[0023] A further technical solution of the present invention is: the outer periphery of the air inlet hood is provided with an inclined drainage groove.

[0024] When the fracturing truck is operating outdoors, rainwater flows through the outer wall into the drainage trough during rainy weather, and then through the thin drainage pipe to the ground, preventing rainwater flowing down the air intake hood from flowing into the air intake of the air intake hood and being sucked into the main motor by the fan.

[0025] The air inlet and outlet of the air inlet hood adopt a vertical structure to increase the number of noise reflections. The air inlet hood is a vertically set structure, that is, the air inlet hood adopts a slender structure, which can effectively prevent noise diffusion. The inner wall of the air inlet hood is lined with sound-absorbing cotton, and the inner side of the sound-absorbing cotton is lined with a perforated plate. The perforated plate is a metal plate with a large number of holes. When noise is reflected inside the air inlet hood, it enters the perforated plate through the holes and is difficult to be reflected back to the air inlet duct. The noise is reflected multiple times between the perforated plate and the outer shell and absorbed by the sound-absorbing cotton between the perforated plate and the outer shell, which achieves the purpose of noise reduction.

[0026] A further technical solution of the present invention is: the drive system and the fracturing pump system are connected by a transmission component, and the first heat dissipation system is placed above the transmission component.

[0027] The first cooling system makes full use of the space between the drive system and the fracturing pump system, ensuring that the space of the fracturing truck is fully utilized.

[0028] A further technical solution of the present invention is: the first heat dissipation system includes a mounting bracket and an oil-cooled fan placed on the mounting bracket, wherein the air inlet of the oil-cooled fan is arranged facing the transmission component.

[0029] The oil-cooled fan has an open, elevated structure underneath, resulting in a large air intake area and high efficiency.

[0030] A further technical solution of the present invention is: the fracturing pump system includes a fracturing pump, the lubricating oil pipeline is used to circulate and remove heat from the fracturing pump, and the lubricating oil pipeline is placed on the mounting bracket and between the air inlet and air outlet of the oil cooling fan.

[0031] The heat generated by the fracturing pump is carried away by the lubricating oil. The space between the drive system and the fracturing pump system is used to fully dissipate the heat from the lubricating oil, so that the lubricating oil returns to the fracturing pump after cooling and can be reused, thereby circulating and removing the heat from the fracturing pump.

[0032] The heat generated by the fracturing pump is dissipated by the lubricating oil in the lubricating oil pipeline between the air inlet and outlet of the oil-cooled fan; the motor and electrical control room are cooled by their own internal fans and air ducts. The cooling systems of a single fracturing truck are designed to not interfere with each other; if multiple fracturing trucks are placed side by side, the cooling between the trucks will also not interfere with each other.

[0033] A further technical solution of the present invention is that at least two fracturing trucks are arranged side by side. When there are multiple fracturing trucks in the present invention, their heat dissipation will not interfere with each other.

[0034] The beneficial effects of this invention are as follows: In this invention, the fracturing pump system dissipates heat through a first heat dissipation system, with the air inlet of the first heat dissipation system facing downwards and the air outlet facing upwards; the drive system dissipates heat using its internal air ducts and a second heat dissipation system, with the air inlet of the second heat dissipation system facing downwards. The cold air entering from the second heat dissipation system passes through the air ducts inside the drive system and is discharged from the side of the drive system; the air ducts inside the electrical control room cooperate with the third heat dissipation system, allowing cold air to enter from one side of the electrical control room, pass through the internal air ducts of the electrical control room, and be discharged from the other side of the electrical control room; it can be seen that the first, second, and third heat dissipation systems fully utilize the structural features of the fracturing truck itself, ensuring that the heat dissipation of a single fracturing truck does not interfere with each other. At the same time, considering the working conditions of multiple trucks arranged side by side at the fracturing site, the optimized design prevents the hot air discharged by the fracturing truck from being sucked into adjacent heat dissipation systems, effectively improving the heat dissipation efficiency of single and multiple fracturing trucks.

[0035] This invention can effectively prevent dust and water, improve the protection level of the motor, and increase the motor life; the air inlet shroud has a vertical air inlet and outlet direction, and the air inlet shroud adopts a slender structure, and the inner wall is equipped with suction cotton, which can effectively reduce motor noise.

[0049] Example 1:

[0050] Figure 1-10 illustrates a fracturing truck with a cooling system, including a fracturing pump system 1, a drive system 3, and an electrical control room 4. The drive system 3 is electrically connected to and controlled by the electrical control room 4, and is used to drive the fracturing pump system 1 to perform fracturing operations. The fracturing truck also includes:

[0051] The first heat dissipation system 2 is used to dissipate heat from the fracturing pump system 1. The air inlet of the first heat dissipation system 2 faces downward and the air outlet opening faces upward. A lubricating oil pipe 11 is provided between the air inlet and the air outlet of the first heat dissipation system 2 for circulating and carrying away the heat of the fracturing pump system 1.

[0052] The second heat dissipation system 5 is used to dissipate heat from the drive system 3. The air inlet of the second heat dissipation system 5 faces downward and the air outlet faces the side of the fracturing vehicle.

[0053] The third heat dissipation system 6 is used to dissipate heat from the electrical control room 4. The first air inlet 61 of the third heat dissipation system 6 is located on one side of the electrical control room 4, and the first air outlet 62 of the third heat dissipation system 6 is located on the other side of the electrical control room 4 with its opening facing upward.

[0054] In this embodiment, the electrical control room 4 is a VFD room.

[0055] In this embodiment, the third heat dissipation system 6 includes a guide member 621 placed on the first air outlet 62 of the third heat dissipation system 6. The guide member 621 is used to switch the airflow direction of the first air outlet 62 of the third heat dissipation system 6 to obliquely upward.

[0056] Cold air enters the electrical control room 4 from the first air inlet 61 on one side. The cold air carries away heat through the air duct of the electrical control room 4's own fan, forming hot air. The hot air is discharged upward from the first air outlet 62 on the other side of the electrical control room 4 under the action of the guide 621, thereby preventing the fracturing trucks from being sucked in by adjacent fracturing trucks when multiple fracturing trucks are set up.

[0057] The electrical control room 4 uses its own fan and duct for air cooling. Hot air is blown directly upwards through the opening on its side, without affecting the air intake of other equipment.

[0058] In this embodiment, the guide member 621 is a triangular prism, with the top surface of the triangular prism open and the side surface of the triangular prism open and connected to the first air outlet 62 of the third heat dissipation system 6.

[0059] The adjacent quadrilateral faces of the triangular prism are open, and the hot air coming out of the electrical control room 4 is discharged obliquely upward under the action of the guide 621, avoiding heat dissipation interference between adjacent fracturing trucks.

[0060] In this embodiment, as shown in Figure 3, hollow black arrows represent air intake, and solid black arrows represent hot air exhaust; a single electrical control room 4 draws in air horizontally from one side and then exhausts hot air upwards from the opposite side.

[0061] As shown in Figure 3, when multiple fracturing trucks are placed side by side, the electrical control room 4 is also placed side by side. The hot air discharged from the electrical control room 4 of the previous VFD room is blown upward and will not be sucked in from the side by the next electrical control room 4.

[0062] In this embodiment, the guide member 621 can be moved into the electrical control room 4.

[0063] The guide component is an openable and closable structure. When in use, it unfolds to guide and dissipate heat from the electrical control room. When not in use, it can be stored inside the electrical control room, thus not increasing the transport width. As shown in Figure 3, the guide component 621 of the electrical control room 4 can be moved to the closed position when not in use, without increasing the width of the fracturing truck during travel.

[0064] In this embodiment, the third heat dissipation system 6 further includes a second air inlet 63 and a second air outlet 64. The second air inlet 63 is located on one or both sides of the rear of the electrical control room 4, and the second air outlet 64 is located at the rear of the electrical control room 4. In this embodiment, to improve the heat dissipation effect of the electrical control room 4, the second air inlet 63 is located on the rear side of the electrical control room 4, and the second air outlet 64 is located at the rear, which can dissipate the internal heat of the rear of the electrical control room 4.

[0065] In this embodiment, the second heat dissipation system 5 includes an air inlet shroud 51 and a second heat dissipation system outlet 59. The air inlet shroud 51 is vertically arranged, the air inlet 58 of the second heat dissipation system 5 is located at the bottom of the air inlet shroud 51, the air outlet 54 of the air inlet shroud 51 is located on the side of the air inlet shroud 51 near the drive system 3 and is connected to the drive system 3, and the second heat dissipation system outlet 59 is located on one or two sides of the drive system 3 for dissipating heat from the windings and bearings inside the drive system 3.

[0066] The drive system 3 uses its own fan to draw in cool air from the air inlet 58 of the air inlet hood, and then enters the drive system 3 through the air outlet 54 of the air inlet hood to remove heat. The hot air is discharged through the air outlet 59 of the second heat dissipation system on the side of the drive system 3 for air cooling. The fan used in the drive system 3 has high air pressure, and the hot air can be directly blown to the far sides of the fracturing vehicle without affecting the air intake of other equipment.

[0067] In this embodiment, the air inlet shroud 51 is relatively long, and the air outlet 54 of the air inlet shroud extends to the motor bearing area. The cooling air entering the air inlet shroud 51 can carry away the heat from the bearing and winding. The heat is discharged from the air outlet 59 of the second heat dissipation system on the motor housing, thereby improving the service life of the motor.

[0068] In this embodiment, the outer shell of the air inlet shroud 51 is made of steel and has an air inlet 58. The air inlet 58 is installed with its opening facing downwards, and the air outlet 54 is located on the upper side of the air inlet shroud 51. The air inlet direction is perpendicular to the air outlet direction.

[0069] In this embodiment, the air inlet 58 of the air inlet shroud 51 is an inclined surface with the opening facing the drive system 3, the air inlet 58 of the air inlet shroud 51 is provided with a filter screen 57, and the inner wall of the air inlet shroud 51 is provided with sound-absorbing cotton 56 with a perforated plate 55.

[0070] The air inlet 58 of the air inlet hood adopts an inclined structure, which can increase the air intake area and prevent rainwater from being blown into the air inlet by the wind. The air inlet 58 of the air inlet hood adopts a gas-liquid filter screen, which is composed of multiple layers of disordered metal wires. The capillary action of the metal wires can effectively capture water mist and dust in the air inlet.

[0071] In this embodiment, the air inlet shroud 51 is provided with an inclined drainage groove 52 on its outer periphery.

[0072] When the fracturing truck is running outdoors, rainwater flows through the outer wall into the drainage trough 52 during rainy weather. The slender drainage pipe 53 connected at the lowest point of the drainage trough drains the water to the ground, preventing the rainwater flowing down the air intake hood 51 from flowing into the air intake hood 58 and being sucked into the main motor by the fan.

[0073] The air inlet and outlet of the air inlet hood 51 adopt a vertical structure to increase the number of noise reflections. The air inlet hood 51 is a vertically set structure, that is, the air inlet hood 51 adopts a slender structure, which can effectively prevent noise diffusion. The inner wall of the air inlet hood 51 is provided with sound-absorbing cotton 56, and the inner side of the sound-absorbing cotton 56 is provided with a perforated plate 55. The perforated plate 55 is a metal plate with a large number of holes. When noise is reflected inside the air inlet hood 51, it enters the perforated plate 55 through the holes and is difficult to be reflected back to the air inlet duct. The noise is reflected multiple times between the perforated plate 55 and the outer shell and is absorbed by the sound-absorbing cotton 56 between the perforated plate 55 and the outer shell, thus achieving the purpose of noise reduction.

[0074] In this embodiment, the outer shell of the air inlet shroud 51 is provided with drainage grooves 52 on three sides, but not on the contact surface with the drive system 3. The drainage grooves 52 have a certain slope, and a drain pipe 53 is provided at the lowest point of the drainage grooves 52.

[0075] In this embodiment, as shown in Figure 2, hollow black arrows represent air intake, and solid black arrows represent hot air exhaust. The single drive system 3 draws in air from the front from bottom to top, and then exhausts hot air from both sides. The cooling fan of the drive system 3 has high air pressure, which can blow hot air to the sides and far away, without affecting the motor's own air intake or the air intake of other nearby devices.

[0076] As shown in Figure 2, when multiple fracturing trucks are placed side by side, the drive system 3 is also placed side by side. The hot air between every two drive systems 3 will collide and generate turbulence in the middle empty space, and then flow vertically upward naturally without affecting the air intake of itself and other equipment.

[0077] In this embodiment, the drive system 3 includes a motor.

[0078] In this embodiment, the drive system 3 and the fracturing pump system 1 are connected by a transmission component, and the first heat dissipation system 2 is placed above the transmission component.

[0079] The first cooling system 2 makes full use of the space between the drive system 3 and the fracturing pump system 1 to ensure that the space of the fracturing truck is fully utilized.

[0080] In this embodiment, the first heat dissipation system 2 includes a mounting bracket 21 and an oil-cooled fan 22 placed on the mounting bracket 21, with the air inlet of the oil-cooled fan 22 facing the transmission component.

[0081] The oil-cooled fan 22 has an open, overhead structure underneath, which provides a large air intake area and high efficiency.

[0082] In this embodiment, the oil-cooled fan 22 uses four fans blowing air vertically upwards, which conforms to the natural principle of hot air rising and does not interfere with the air intake of other cooling equipment.

[0083] In this embodiment, the fracturing pump system 1 includes a fracturing pump, and the lubricating oil pipeline 11 is used to circulate and remove heat from the fracturing pump. The lubricating oil pipeline 11 is placed on the mounting bracket 21 and positioned between the air inlet and air outlet of the oil cooling fan 22.

[0084] The heat generated by the fracturing pump is carried away by the lubricating oil. The space between the drive system 3 and the fracturing pump system 1 is used to fully dissipate the heat from the lubricating oil, so that the lubricating oil returns to the fracturing pump after cooling and can be reused, thereby circulating and removing the heat from the fracturing pump.

[0085] The heat generated by the fracturing pump is dissipated by the lubricating oil in the lubricating oil pipeline between the air inlet and outlet of the oil-cooled fan 22; the drive system 3 and the electrical control room 4 are dissipated through their own internal fans and air ducts. The cooling systems of a single fracturing truck are designed to not interfere with each other; if multiple fracturing trucks are placed side by side, the cooling between the trucks will also not interfere with each other.

[0086] In another embodiment, two fracturing trucks are arranged side by side. This ensures that heat dissipation between them does not interfere with each other.

[0087] The working principle of this invention is as follows: The fracturing pump system 1 dissipates heat through the first heat dissipation system 2, with the air inlet of the first heat dissipation system 2 facing downwards and the air outlet facing upwards; the drive system 3 dissipates heat using its internal air duct and the second heat dissipation system 5, with the air inlet of the second heat dissipation system 5 facing downwards. The cold air entering from the second heat dissipation system 5 passes through the air duct inside the drive system 3 and is discharged from the side of the drive system 3; the air duct inside the electrical control room 4, in conjunction with the third heat dissipation system 6, allows cold air to enter from the first air inlet 62 of the electrical control room 4, pass through the internal air duct of the electrical control room 4, and be discharged from the first air outlet 63 of the electrical control room 4; it can be seen that the first heat dissipation system 2, the second heat dissipation system 5, and the third heat dissipation system 6 make full use of the structural features of the fracturing truck itself, ensuring that the heat dissipation of the equipment of a single fracturing truck does not interfere with each other. At the same time, considering the working conditions of multiple trucks arranged side by side at the fracturing site, the optimized design prevents the hot air discharged by the fracturing truck from being sucked into the adjacent heat dissipation system, effectively improving the heat dissipation efficiency of the fracturing truck for both single and multiple trucks.

[0088] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
