Description

Technical Field

[0001] The invention relates to the technical field of heat dissipation of a fracturing vehicle, and in particular to a fracturing vehicle with a heat dissipation system. Background Art

[0002] The fracturing trucks used in modern fracturing must be equipped with a cooling system to dissipate heat from the fracturing equipment on the truck. However, due to the unreasonable design of the traditional fracturing truck cooling system, it is easy for the exhaust hot air to be re-inhaled between the equipment of a single vehicle or between multiple vehicles, resulting in poor heat dissipation of the fracturing truck. In addition, large and medium-sized motors with IC36 cooling method currently generally use independent fans to blow air to dissipate heat from the motors. The poor waterproof and dustproof capabilities of the fan inlet seriously affect the life of the motor; the fan generates high noise, which seriously affects the health of people around the equipment.

[0003] Existing heat dissipation systems for fracturing vehicles, such as a self-elevating electric fracturing skid with patent number CN213331051U, include a base, on which a fracturing pump, a variable frequency motor and supporting equipment are integrated, and a lifting device is also integrated on the base, which is used to lift the base to a loading and unloading height H; compared with the diesel engine drive mode, the fuel of the electric drive mode is changed from diesel to electricity, the operating cost is reduced, the low-speed performance is stable, and the maximum pressure can be stably output at a small displacement, and the noise is small, it is not easy to cause environmental pollution, and it can meet environmental protection requirements; the present invention adopts variable frequency motor drive, realizes stepless regulation of pressure and flow, zero emission, energy saving and environmental protection, and comes with a lifting component, and does not require the cooperation of a crane during transportation and transfer, which greatly improves the transfer and moving speed, saves production costs, and improves production efficiency. What is disclosed is the heat dissipation structure of the fracturing pump, but there is no relevant record in the prior art about how to avoid interference when the various components of the entire fracturing vehicle dissipate heat. Summary of the invention

[0004] The purpose of the present invention is to provide a fracturing truck with a heat dissipation system, which solves the problem of how to avoid interference between the heat dissipation systems of the fracturing truck itself and heat dissipation interference between multiple trucks.

[0005] The present invention is implemented as follows: a fracturing vehicle with a heat dissipation system includes a fracturing pump system, a drive system and an electric control room, wherein the drive system is controlled by the electric control room to drive the fracturing pump system to perform fracturing operations, and the fracturing vehicle also includes:

[0006] A first heat dissipation system, wherein the first heat dissipation system is used to dissipate heat for the fracturing pump system, wherein the air inlet of the first heat dissipation system faces downward and the air outlet opens upward, and a lubricating oil pipeline for circulating and removing heat from the fracturing pump system is provided between the air inlet and the air outlet of the first heat dissipation system;

[0007] A second heat dissipation system, the second heat dissipation system is used to dissipate heat from the drive system, the air inlet of the second heat dissipation system is downward and the air outlet is toward the side of the fracturing vehicle;

[0008] The third heat dissipation system is used to dissipate heat in the electric control room. The first air inlet of the third heat dissipation system is located on one side of the electric control room, and the first air outlet of the third heat dissipation system is located on the other side of the electric control room and opens upward.

[0009] In the present invention, the fracturing pump system dissipates heat through the first heat dissipation system, the air inlet of the first heat dissipation system faces downward and the air outlet faces upward; the driving system dissipates heat by using its internal air duct and the second heat dissipation system, the air inlet of the second heat dissipation system faces downward, and the cold air entering from the second heat dissipation system passes through the air duct inside the driving system and is discharged from the side of the driving system; the air duct inside the electric control room cooperates with the third heat dissipation system, so that the cold air enters from the first air inlet of the electric control room, passes through the internal air duct of the electric control room, and is discharged from the first air outlet of the electric control room; it can be seen that the first heat dissipation system, the second heat dissipation system and the third heat dissipation system make full use of the structural characteristics of the fracturing vehicle itself, which not only makes the heat dissipation of the equipment of a single fracturing vehicle non-interfere with each other, but also takes into account the working condition of multiple vehicles arranged side by side at the fracturing site, and through the optimized design, the hot air discharged from the fracturing vehicle will not be sucked into the adjacent heat dissipation system, which effectively improves the heat dissipation efficiency of a single fracturing vehicle and multiple vehicles.

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

[0011] Cold air enters the electric control room from the first air inlet on one side of the electric control room, and the cold air takes away heat through the air duct of the fan in the electric control room to form hot air, which is discharged upward from the first air outlet on the other side of the electric control room under the action of the guide member, thereby avoiding being sucked in by adjacent fracturing trucks when multiple fracturing trucks are set up.

[0012] The electric control room is cooled and radiated by its own fan duct, and the hot air is blown directly upward through the opening on the upper side thereof, without affecting the air intake of other equipment. A further technical solution of the present invention is that the guide member is a triangular prism type, 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.

[0013] The adjacent quadrilateral surfaces of the triangular prism are open, and the hot air coming out of the electric control room is discharged obliquely upward under the action of the guide member, avoiding the heat dissipation interference of the adjacent fracturing vehicles.

[0014] A further technical solution of the present invention is that the guide member can be moved into the electric control room.

[0015] The guide piece is an openable and closable structure. It is unfolded when in use to guide and dissipate the heat in the electric control room. It can be stored inside the electric control room when not in use, thereby not increasing the transportation width.

[0016] A further technical solution of the present invention is: the third heat dissipation system also includes a second air inlet and a second air outlet, the second air inlet is arranged on one side or both sides of the rear part of the electric control room, and the second air outlet is arranged at the rear end of the electric control room.

[0017] In order to achieve a better heat dissipation effect in the electric control room, a second air inlet is arranged on the rear side of the electric control room, and a second air outlet is arranged at the rear end, so as to dissipate the internal heat at the rear of the electric control room.

[0018] A further technical solution of the present invention is: the second heat dissipation system includes an air inlet hood and an air outlet of the second heat dissipation system, the air inlet hood is vertically arranged, the air inlet of the second heat dissipation system is placed at the bottom of the air inlet hood, the air outlet of the air inlet hood is placed on the side of the air inlet hood close to the drive system and is connected to the drive system, and the air outlet of the second heat dissipation system is placed on the side of the drive system for dissipating heat from windings and bearings inside the drive system.

[0019] The drive system uses its own fan to suck in cold air from the air inlet of the air inlet hood, and then blows it into the drive system through the air outlet of the air inlet hood to take away the heat. The hot air is discharged through the air outlet on the side of the drive system for air cooling and heat dissipation. The fan used in the drive system has high wind pressure, and the hot air can be directly blown to the far sides of the fracturing truck without affecting the air intake of other equipment.

[0020] A further technical solution of the present invention is: the air inlet of the air inlet hood is an inclined surface opening toward the drive system, the air inlet of the air inlet hood is provided with a filter screen, and the inner wall of the air inlet hood is provided with sound-absorbing cotton with a perforated plate.

[0021] The air inlet adopts an inclined structure, which can increase the air inlet area and prevent rain from being blown to the air inlet by the wind; the air inlet adopts an air-liquid filter, 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 at the air inlet.

[0022] A further technical solution of the present invention is that an inclined drainage groove is provided on the outer periphery of the air inlet cover.

[0023] When the fracturing truck is operating outdoors in rainy weather, the rainwater flows through the outer wall into the drainage ditch and then is discharged to the ground through a slender drainage pipe, preventing the rainwater flowing down the air inlet hood from flowing to the air inlet of the air inlet hood and being sucked into the main motor by the fan.

[0024] 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 arranged structure, that is, the air inlet hood adopts a slender structure, which can effectively prevent the spread of noise. Sound-absorbing cotton is arranged on the inner wall of the air inlet hood, and a perforated plate is arranged on the inner side of the sound-absorbing cotton. The perforated plate is a metal plate with a large number of holes. When the noise is reflected in 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 many times between the perforated plate and the outer shell and absorbed by the sound-absorbing cotton between the perforated plate and the outer shell, thereby achieving the purpose of noise reduction.

[0025] A further technical solution of the present invention is: the driving system and the fracturing pump system are connected via a transmission member, and the first heat dissipation system is placed above the transmission member.

[0026] The first heat dissipation system makes full use of the space between the drive system and the fracturing pump system to ensure that the space of the fracturing vehicle is fully utilized.

[0027] A further technical solution of the present invention is: the first heat dissipation system includes a mounting frame and an oil cooling fan placed on the mounting frame, and an air inlet of the oil cooling fan is arranged toward the transmission member.

[0028] The oil cooling fan has an open overhead structure below, which provides a large air suction area and high efficiency.

[0029] 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 frame and between the air inlet and the air outlet of the oil cooling fan.

[0030] The heat generated by the fracturing pump is taken out through the lubricating oil, and the space between the drive system and the fracturing pump system is used to fully dissipate the heat of the lubricating oil, so that the lubricating oil returns to the fracturing pump after cooling and is used again, thereby circulating and taking away the heat in the fracturing pump.

[0031] The heat generated by the operation of the fracturing pump is all carried to the air inlet and outlet of the oil cooling fan through the lubricating oil in the lubricating oil pipeline for dissipation; the motor and the electric control room dissipate heat through their own internal fans and air ducts. The cooling systems of a single fracturing truck are designed not to interfere with each other; if multiple fracturing trucks are placed side by side, the heat dissipation between the trucks will not interfere with each other.

[0032] A further technical solution of the present invention is that: the number of the fracturing trucks is at least two and they are arranged side by side. When there are multiple fracturing trucks in the present invention, the heat dissipation between the trucks will not interfere with each other.

[0033] Beneficial effects of the present invention: In the present invention, the fracturing pump system dissipates heat through the first heat dissipation system, the air inlet of the first heat dissipation system faces downward and the air outlet faces upward; the driving system dissipates heat by using its internal air duct and the second heat dissipation system, the air inlet of the second heat dissipation system faces downward, and the cold air entering from the second heat dissipation system passes through the air duct inside the driving system and is discharged from the side of the driving system; the air duct inside the electric control room cooperates with the third heat dissipation system, so that the cold air enters from one side of the electric control room, passes through the internal air duct of the electric control room, and is discharged from the other side of the electric control room; it can be seen that the first heat dissipation system, the second heat dissipation system and the third heat dissipation system make full use of the structural characteristics of the fracturing vehicle itself, which not only makes the heat dissipation of a single fracturing vehicle non-interfering with each other, but also takes into account the working condition of multiple vehicles arranged side by side at the fracturing site, and through the optimized design, the hot air discharged from the fracturing vehicle will not be sucked into the adjacent heat dissipation system, which effectively improves the heat dissipation efficiency of a single fracturing vehicle and multiple vehicles.

[0034] The present invention can effectively prevent dust and water, improve the protection level of the motor, and increase the life of the motor; the air inlet and outlet directions of the air inlet cover are vertical, and the air inlet cover adopts a slender structure, and the inner wall is provided with suction cotton, which can effectively reduce the noise of the motor.

[0051] A second heat dissipation system 5, 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;

[0052] The third cooling system 6 is used to dissipate heat for the electric control room 4. The first air inlet 61 of the third cooling system 6 is located on one side of the electric control room 4. The first air outlet 62 of the third cooling system 6 is located on the other side of the electric control room 4 and opens upward.

[0053] In this embodiment, the electric control room 4 is a VFD room.

[0054] In this embodiment, the third heat dissipation system 6 includes a guide member 621 disposed on the first air outlet 62 of the third heat dissipation system 6, and the guide member 621 is used to switch the wind direction of the first air outlet 62 of the third heat dissipation system 6 to obliquely upward.

[0055] Cold air enters the electric control room 4 from the first air inlet 61 on one side of the electric control room 4, and the cold air takes away heat through the air duct of the fan in the electric control room 4 to form hot air, which is discharged upward from the first air outlet 62 on the other side of the electric control room 4 under the action of the guide member 621, thereby avoiding being sucked into the adjacent fracturing trucks when multiple fracturing trucks are set up.

[0056] The electric control room 4 uses its own fan duct for air cooling and heat dissipation, and the hot air is blown directly upward through the opening on the upper side thereof without affecting the air intake of other equipment.

[0057] In this embodiment, the guide member 621 is in the shape of a triangular prism, the top surface of the triangular prism is open, and the side surface of the triangular prism is open and communicated with the first air outlet 62 of the third heat dissipation system 6 .

[0058] The adjacent quadrilateral surfaces of the triangular prism are open, and the hot air from the electric control room 4 is discharged obliquely upward under the action of the guide member 621, thereby avoiding the heat dissipation interference of the adjacent fracturing vehicles.

[0059] In this embodiment, if Figure 3 As shown, the hollow black arrows represent air intake, and the solid black arrows represent exhaust hot air; a single electric control room 4 inhales air horizontally from one side, and then exhausts the hot air upward on the opposite side.

[0060] like Figure 3 As shown, when multiple fracturing trucks are placed side by side, the electric control rooms 4 are also placed side by side, and the hot air exhausted from the electric control room 4 of the previous VFD room is blown upward and will not be sucked from the side by the next electric control room 4.

[0061] In this embodiment, the guide member 621 can be moved into the electric control room 4 .

[0062] The guide piece is an openable and closable structure. It is unfolded when in use to guide and dissipate the heat in the electric control room. It can be stored inside the electric control room when not in use, thus not increasing the transportation width. Figure 3 As shown, the guide member 621 of the electric control room 4 can be moved to close when not in use, without increasing the width of the fracturing vehicle during travel.

[0063] In this embodiment, the third heat dissipation system 6 further includes a second air inlet 63 and a second air outlet 64, wherein the second air inlet 63 is arranged on one side or both sides of the rear of the electric control room 4, and the second air outlet 64 is arranged at the rear end of the electric control room 4. In this embodiment, in order to achieve a better heat dissipation effect of the electric control room 4, the second air inlet 63 is arranged on the rear side of the electric control room 4, and the second air outlet 64 is arranged at the rear end, so that the internal heat at the rear of the electric control room 4 can be dissipated.

[0064] In this embodiment, the second heat dissipation system 5 includes an air inlet hood 51 and a second heat dissipation system air outlet 59. The air inlet hood 51 is vertically arranged. The air inlet 58 of the second heat dissipation system 5 is placed at the bottom of the air inlet hood 51. The air outlet 54 of the air inlet hood 51 is placed on the side of the air inlet hood 51 close to the drive system 3 and is connected to the drive system 3. The second heat dissipation system air outlet 59 is placed on one or two sides of the drive system 3 for dissipating heat from the windings and bearings inside the drive system 3.

[0065] The drive system 3 uses its own fan to suck in cold air from the air inlet 58 of the air inlet cover, and then enters the drive system 3 through the air outlet 54 of the air inlet cover to take away heat, and the hot air is discharged through the second heat dissipation system air outlet 59 on the side of the drive system 3 for air cooling and heat dissipation; the fan used in the drive system 3 has a high wind 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.

[0066] In this embodiment, the air inlet cover 51 is longer, and the air outlet 54 of the air inlet cover extends to the motor bearing position. The cooling air entering the air inlet cover 51 can take away the heat of the bearings and windings, and the heat is discharged from the second heat dissipation system outlet 59 on the motor housing, thereby increasing the service life of the motor.

[0067] In this embodiment, the outer shell of the air inlet cover 51 is made of steel and has an air inlet 58. The air inlet 58 is installed with its opening facing downward, and the air outlet 54 is on the upper side of the air inlet cover 51. The air inlet direction is perpendicular to the air outlet direction.

[0068] In this embodiment, the air inlet 58 of the air inlet cover 51 is an inclined surface opening toward the driving system 3 , the air inlet 58 of the air inlet cover 51 is provided with a filter 57 , and the inner wall of the air inlet cover 51 is provided with sound-absorbing cotton 56 with a perforated plate 55 .

[0069] The air inlet 58 of the air inlet hood adopts an inclined structure, which can increase the air inlet area and prevent rain from being blown to the air inlet by the wind; the air inlet 58 of the air inlet hood adopts an air-liquid filter, 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 at the air inlet.

[0070] In this embodiment, an inclined drainage groove 52 is provided on the outer periphery of the air inlet cover 51 .

[0071] When the fracturing truck is operating outdoors in rainy weather, rainwater flows through the outer wall into the drainage groove 52 and is discharged to the ground through the slender drainage pipe 53 connected to the lowest point of the drainage groove, so as to prevent rainwater flowing down the air inlet cover 51 from flowing to the air inlet port 58 of the air inlet cover and being sucked into the main motor by the fan.

[0072] 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 arranged structure, that is, the air inlet hood 51 adopts a slender structure, which can effectively prevent noise diffusion. Sound-absorbing cotton 56 is arranged on the inner wall of the air inlet hood 51, and a perforated plate 55 is arranged on the inner side of the sound-absorbing cotton 56. The perforated plate 55 is a metal plate with a large number of holes. When the noise is reflected in 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 many 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, thereby achieving the purpose of noise reduction.

[0073] In this embodiment, drainage grooves 52 are provided on three sides of the outer shell of the air inlet cover 51 , but not on the contact surface with the drive system 3 . The drainage grooves 52 have a certain slope, and a drainage pipe 53 is provided at the lowest point of the drainage grooves 52 .

[0074] In this embodiment, if Figure 2 As shown, the hollow black arrows represent air intake, and the solid black arrows represent exhaust of hot air; a single drive system 3 inhales air from the front from bottom to top, and then exhausts the hot air from both sides; the cooling fan of the drive system 3 has a large wind pressure, which can blow the hot air far to both sides without affecting the motor's own air intake, nor affecting the air intake of other nearby equipment.

[0075] like Figure 2 As shown, when multiple fracturing vehicles are placed side by side, the drive systems 3 are also placed side by side. The hot air between every two drive systems 3 will collide in the empty space in the middle to generate turbulence, and then flow vertically upward naturally without affecting the air intake of itself and other equipment.

[0076] In this embodiment, the driving system 3 includes a motor.

[0077] In this embodiment, the driving system 3 is connected to the fracturing pump system 1 via a transmission member, and the first heat dissipation system 2 is placed above the transmission member.

[0078] The first heat dissipation system 2 fully utilizes the space between the driving system 3 and the fracturing pump system 1 to ensure that the space of the fracturing vehicle is fully utilized.

[0079] In this embodiment, the first heat dissipation system 2 includes a mounting frame 21 and an oil cooling fan 22 disposed on the mounting frame 21 , and an air inlet of the oil cooling fan 22 is disposed toward the transmission member.

[0080] The oil cooling fan 22 has an open overhead structure below, which has a large air suction area and high efficiency.

[0081] In this embodiment, the oil cooling fan 22 uses four fans to blow air vertically upward, which conforms to the natural principle that hot air rises and does not interfere with the air intake of other cooling equipment.

[0082] 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 frame 21 and between the air inlet and the air outlet of the oil cooling fan 22 .

[0083] The heat generated by the fracturing pump is taken out by the lubricating oil, and the space between the drive system 3 and the fracturing pump system 1 is used to fully dissipate the heat of the lubricating oil, so that the lubricating oil returns to the fracturing pump after cooling and is used again, thereby circulating and taking away the heat in the fracturing pump.

[0084] The heat generated by the operation of the fracturing pump is all carried to the air inlet and outlet of the oil cooling fan 22 through the lubricating oil in the lubricating oil pipeline for heat dissipation; the drive system 3 and the electric control room 4 dissipate heat through their own internal fans and air ducts. The heat dissipation systems of a single fracturing truck are designed not to interfere with each other; if multiple fracturing trucks are placed side by side, the heat dissipation between the trucks will not interfere with each other.

[0085] As another embodiment, there are two fracturing vehicles arranged side by side, so that the heat dissipation between them will not interfere with each other.

[0086] The working principle of the present invention is as follows: the fracturing pump system 1 dissipates heat through the first heat dissipation system 2, the air inlet of the first heat dissipation system 2 faces downward and the air outlet faces upward; the driving system 3 dissipates heat by using its internal air duct and the second heat dissipation system 5, the air inlet of the second heat dissipation system 5 faces downward, and the cold air entering from the second heat dissipation system 5 passes through the air duct inside the driving system 3 and is discharged from the side of the driving system 3; the air duct inside the electric control room 4 cooperates with the third heat dissipation system 6, so that the cold air enters from the first air inlet 62 of the electric control room 4, passes through the internal air duct of the electric control room 4, and is discharged from the first air outlet 63 of the electric 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 characteristics of the fracturing vehicle itself, which not only makes the heat dissipation of the equipment of a single fracturing vehicle not interfere with each other, but also considers the working condition of multiple vehicles arranged side by side at the fracturing site, and through the optimized design, the hot air discharged from the fracturing vehicle will not be sucked into the adjacent heat dissipation system, which effectively improves the heat dissipation efficiency of a single fracturing vehicle and multiple vehicles.

[0087] 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 in the protection scope of the present invention.
