Description

Heat abstractor and turbine fracturing equipment that has heat abstractor

Technical Field

The invention relates to a heat dissipation device and turbine fracturing equipment with the same.

Background

The radiator forms applied to the turbine fracturing equipment at present are a vertical radiator, a horizontal radiator and a square cabin type radiator. Among them, the vertical radiator occupies a small installation space, but has a large noise, and the blown hot air affects other parts of the equipment, and is not suitable for some cases. The hot-blast upwards that horizontal radiator blew out can not lead to the fact the influence to other part and equipment, but because be the core formula and be the multilayer and arrange, the heat dissipation capacity of every layer of core is lower relatively, and arranging of multilayer core makes the trafficability characteristic of silica dust and guar gum powder poor moreover, blocks up the core fin easily, causes the heat dissipation capacity not enough, needs frequent maintenance to also there is the shortcoming that the noise is big. In addition, for the vertical radiator and the horizontal radiator, the core body can be collided by sand and stone particles, branches and the like flying in the driving process to cause the damage of the core body, so that the use cost of equipment is increased.

Although the square cabin type radiator can solve the problems of equipment arrangement and core blockage prevention, the problem of high noise still exists. In order to solve the problem of high noise of the shelter type radiator, some turbine fracturing equipment adopts measures of reducing the rotating speed of a fan of the radiator, enlarging the radiator, or adding a noise reduction cabin body outside the equipment, and the like, but the noise reduction modes bring overweight problems to the equipment.

On the other hand, when the complete fracturing equipment works, the equipment is arranged side by side, the distance between the adjacent equipment is smaller, and the conventional blowing type radiator can influence the heat dissipation of the two adjacent equipment.

Therefore, it is desirable to provide a heat dissipation device to at least partially solve the above problems. The heat dissipation device can be used for turbine fracturing equipment in oil fields, and can also be used for heat dissipation systems of other oil field equipment, generator heat dissipation systems and the like.

Detailed Description

Reference will now be made in detail to the embodiments of the present invention, examples of which are illustrated in the accompanying drawings. What has been described herein is merely a preferred embodiment in accordance with the present invention and other ways of practicing the invention will occur to those skilled in the art and are within the scope of the invention.

The invention provides a heat dissipation device. Fig. 1-9 illustrate various preferred embodiments according to the present invention. It should be noted that the directional terminology mentioned herein is for the purpose of example only and is not intended to be limiting, and that each directional terminology may be understood with reference to the heat dissipation device shown in fig. 1-3. For example, reference herein to "the top of the nacelle" may be understood as being at an end of the nacelle opposite the horizontal when the nacelle is placed on the horizontal, which may or may not have a top wall; by "lateral part of the cabin" is meant that the cabin is connected at a position between its top and the horizontal plane, which is opposite to the outside. The "top and side" of the nacelle are conceptual terms and do not necessarily include a solid structure, for example, as will be described later, the nacelle may be a frame structure composed of uprights and cross members, and the side of the nacelle may be an open structure.

The noise source of the heat dissipation device is mainly divided into two parts: firstly, air is generated by air flow through the heat dissipation core body; and the aerodynamic noise generated by the blade tip of the fan rotating at high speed. The invention has been modified in several ways in order to reduce the noise of these two parts.

Referring first to fig. 1 and 2, taking the heat dissipation apparatus 100 as an example, the heat dissipation apparatus 100 is a square cabin type heat dissipation apparatus, which includes a cabin body composed of a vertical frame structure 1, a heat dissipation core 4, a gas guiding device 6, a noise reduction core 5, and the like. The vertical frame structure 1 may be in the form of a vertical column, and the cabin body having a substantially rectangular parallelepiped structure is formed by connecting cross beams, for example, as shown in fig. 1, two adjacent vertical columns are connected by two parallel cross beams, and a cross beam is connected between the two cross beams, which may be connected in other ways. In other embodiments, not shown, the nacelle may also be a straight-tube nacelle or other form of nacelle.

As shown in fig. 1, in the present embodiment, the cabin is provided with air inlets at four sides thereof and air outlets at the top thereof. In other embodiments, not shown, the location of the air inlet and the air outlet may have various options, for example, the top of the cabin may also be provided with an air inlet and the air outlet may be provided on the side of the cabin where no air inlet is provided. Various arrangements of the air inlets and outlets allow the manufacturer to select the air inlets and outlets according to actual needs.

The heat dissipation core 4 is a vertical structure, preferably a vertical plate-shaped structure shown in fig. 2, disposed in the cabin and located between two adjacent columns and blocking the air inlet, and fins for cooling the air flow are disposed on the heat dissipation core 4. The noise reduction core 5 is disposed at the center of the cabin and is formed into a structure gradually gathering from the bottom of the noise reduction core to the air outlet of the cabin (toward the top in the present embodiment), and preferably, the surface of the noise reduction core 5 facing the air inlet of the cabin (i.e., facing the heat dissipation core 4) is an overall concave streamline curved surface. A gas guiding device 6 is arranged at the gas outlet at the top of the cabin, the gas guiding device 6 being for example a fan, outside which a fan protecting structure 12, for example a protective net, is arranged. A motor 13 is mounted on the fan guard structure 12 by means of a motor mount 14 for powering the gas guiding means 6. In other embodiments, not shown, the gas guiding means 6 may also be a suction fan, a vacuum pump or the like.

With continued reference to fig. 2, it can be seen that each side portion of the cabin is provided with a heat dissipation core 4, each heat dissipation core 4 is formed as a vertical plate-like structure, and all the heat dissipation cores 4 are arranged end to end. During operation of the heat dissipation apparatus 100, the external air of the cabin can be sucked into the cabin from any position on the side surface of the cabin and the air can flow through the heat dissipation core 4 to achieve cooling. Such an arrangement can improve the heat dissipation efficiency of the heat dissipation device 100. Of course, the number of the heat dissipation cores 4 on each side is not limited to one, and a plurality of heat dissipation cores 4 may be provided on each side of the cabin, and arranged side by side up and down or left and right, with the cores connected end to end.

In one embodiment, a pipeline for flowing the target fluid is arranged in the heat dissipation core 4, and the heat dissipation core 4 is configured to allow the gas to exchange heat with the target fluid in the pipeline when flowing through the heat dissipation core 4, so as to cool the target fluid. Referring to fig. 2, an inlet 41 of the piping of the heat dissipation core 4 may be provided at the bottom of the heat dissipation core 4, and an outlet 42 of the target fluid of the heat dissipation core 4 may be provided at the top of the heat dissipation core 4. For example, the target fluid may be oil and such a heat sink is an oil-dissipating heat sink. Alternatively, the target fluid may be water and the heat sink may be a water-dispersed heat sink. Alternatively, a passage may be provided in the heat sink to allow other target fluids to flow therethrough. And preferably, the outer surface of the heat dissipation core 4 is also provided with fins to increase the contact area of the heat dissipation core 4 and the gas.

The flow path of the airflow through the heat sink 100 is shown by the arrows in fig. 4. Referring to fig. 4, the hot air flow can enter the nacelle from the air inlet of the nacelle, and flow through the smooth streamlined curved surface of the noise reduction core 5, the air guiding device 6 in sequence and finally exit the nacelle. Since the heat sink 100 is a suction type heat sink, the operation thereof will not affect other heat sinks located around the heat sink. And the gas flows through the streamline curved surface of the noise reduction core body 5, so that the further noise reduction is realized on the premise of not influencing the gas flow.

The heat sink 100 further includes a temperature sensor 16 and a control device 17, and a communication relationship between the temperature sensor 16, the control device 17, and the motor 13 is shown in fig. 8, and arrows in fig. 8 indicate a transmission direction of signals. Specifically, the temperature sensor 16 is provided at the inlet 41 of the oil passage of the heat radiating core 4 and is configured to sense the temperature of the target fluid at the inlet, and the temperature sensor 16 is capable of transmitting a sensor signal containing sensed temperature information to the control device 17. The control device 17 is communicatively connected to the temperature sensor 16 and the motor 13 controlling the gas guiding device 6, the control device 17 being capable of determining whether the temperature of the target fluid sensed by the temperature sensor 16 is below a predetermined value upon receiving the signal from the temperature sensor 16, and sending a control signal to the motor 13 to control the gas guiding device 6 to operate at an operating rate less than a rated value upon determining that the temperature of the target fluid sensed by the temperature sensor 16 is below the predetermined value. When the gas guiding means 6 is a fan, the control means 17 can control the fan to operate at a rotational speed less than the rated rotational speed when it is determined that the temperature of the target fluid sensed by the temperature sensor 16 is lower than a predetermined value.

It will be appreciated that if the temperature of the target fluid at the inlet is greater than or equal to the predetermined value, the suction force needs to be increased to increase the air flow to achieve the predetermined temperature reduction, so that the operating power of the gas guiding device 6 is increased when the temperature of the target fluid at the inlet is high, and it is not necessary to operate the gas guiding device 6 at a high power when the temperature of the target fluid at the inlet is low. Operating the gas guiding means 6 at a lower operating rate (e.g. rotating the fan at a lower rotational speed) reduces the noise as much as possible.

Preferably, the predetermined value prestored in the control device 17 is set based on the following criteria: the temperature of the intake air sensed by the temperature sensor 16 is less than the predetermined value for at least half of the time during the predetermined operating cycle of the heat sink 100. This arrangement allows the gas guiding device 6 to be operated at a sub-rated operating speed for at least half of the operating time, which arrangement is both energy-saving and avoids unnecessary noise.

Also preferably, and with reference to fig. 5, the noise reducing core 5 includes a core base 51, a perforated outer layer structure 52 and a core noise reducing material 53. The core base 51 has a hollow tower-shaped structure; the perforated outer structure 52 is a tower structure that is hollow and open at the bottom. The surface of the tower-shaped structure can be a smooth curved surface as a whole, or can be composed of a plurality of prismatic surfaces, each outward surface of the punched outer-layer structure 52 is preferably formed into an overall concave shape, and the punched outer-layer structure 52 is fittingly sleeved on the outer side of the core body base 51. Of course, the shape of the punched outer layer structure 52 and the core base 51 does not need to be adapted, and the core base 51 may have any shape as long as a hollow structure is formed with the punched outer layer structure 52. The core noise reduction material 53 is filled between the core base 51 and the punched outer layer. Such a configuration allows the hot gas stream to flow through the streamlined curved surface of the punched outer layer structure 52 and to contact the core noise reducing material 53 via the holes in the punched outer layer structure 52 to achieve noise reduction. The noise reduction core 5 has a hollow structure, and thus does not significantly increase the overall weight of the heat sink 100. Referring to fig. 2 and 3, the outer surface of the heat dissipation core 4 is provided with a louver protective layer 15 for protecting the heat dissipation core 4.

The specific structure of the louver protective layer 15 is shown in fig. 6. The louver shield layer 15 includes a shield layer frame 151 and a plurality of parallel blades 15 mounted within the shield layer frame 151, and the blades 15 include a blade shield plate 1522, a blade punching plate 1521 and a blade noise reduction layer 1523 located between the blade shield plate 1522 and the blade punching plate 1521. When the radiator is in operation, the blades 15 are open, typically at an angle of less than 90 degrees to the vertical, and the noise reducing material is diagonally opposite the radiator core 4. The noise generated at the fins of the radiator core 4 can be absorbed by the noise reducing material on the blades 15. Moreover, the provision of the blade punching plate 1521 can prevent the noise reduction material from being broken and falling off after a long time operation, and being sucked into the gaps between the fins of the heat dissipation core 4 to block the heat dissipation core 4.

When the heat sink 100 is in operation, the blades 15 of the louver shield 15 are in an open state so as to allow smooth air intake. After the heat dissipation device 100 finishes working, the blades 15 of the louver protective layer 15 can be closed to prevent the heat dissipation core 4 from being wetted in rain, prevent the heat dissipation core 4 from sticking silicon dust and guar gum powder suspended in air, and prevent the fins of the heat dissipation core 4 from being blocked due to dust accumulation. The blades 15 of the shutter protective layer 15 can be closed in the driving process, so that the flying impurities such as sand and stone particles and branches can be prevented from damaging the heat dissipation core 4.

A noise reducing structure may also be provided at the top of the heat sink 100, a preferred embodiment of the top structure of the heat sink 100 being shown in fig. 7, fig. 7 showing a bottom view of the top structure. The heat sink 100 includes a tank panel 2, the tank panel 2 including a perforated plate 21 on a bottom surface thereof, an upper panel on a top surface thereof, and a panel noise reducing material 22 between the perforated plate 21 and the upper panel. For illustration purposes, a portion of the perforated plate 21 of the nacelle cover 2 in FIG. 7 is removed to expose the cover noise reducing material 22. This arrangement allows the airflow to pass through the cabin shell 2 and contact the noise reducing material via the holes in the perforated plate 21 to further reduce noise. Moreover, the punching plate 21 can fix the noise reducing material to prevent the noise reducing material from being wound around the blades 15 of the gas guide 6 to damage the blades 15 of the gas guide 6 when the noise reducing material is crushed or dropped.

On the other hand, since dust collection is relatively easily generated at the bottom of the heat radiator 100 and accumulated water is relatively easily generated at the bottom in the rain, maintenance of the heat radiator 100 is required periodically. As shown in fig. 1 and 2, in the present embodiment, a tank bottom guard plate 9 is installed on a tank base 3, a dust exhaust hole 7 is provided on the tank bottom guard plate 9, a manhole is provided on the tank guard plate 2, a manhole cover 10 is covered on the manhole, and a ladder 11 may be connected between the manhole and the bottom guard plate. Maintenance personnel enter the cabin through the manhole and the crawling ladder 11 during maintenance, maintenance can be performed on the interior of the whole heat dissipation device 100 through the maintenance channel on the bottom protection plate, and accumulated water, dust and sundries in the interior can be cleaned out through the dust exhaust hole 7.

The noise reduction core body 5 is relatively easy to generate dust collection blocking noise reduction materials on the surface due to the center of the bottom in the cabin body, the noise reduction effect is reduced, the noise reduction core body 5 is set to be the assembly structure, the noise reduction core body 5 can be conveniently maintained, only the noise reduction materials need to be regularly swept and replaced when maintenance is carried out, and therefore the maintenance time and cost are greatly reduced.

In addition to the specific structure described above, the heat sink 100 may have other alternative structures not shown in the drawings. For example, the noise reduction core 5 may be provided in a pyramid, a cone, a truncated cone, or the like, or may have an irregular shape. Likewise, the motor 13 may be a hydraulically driven motor, an electric motor, a pneumatic motor, or the like. The heat sink 100 may be a lubricating oil radiator, or may be a water radiator of an integrated engine or another type of heat sink.

The invention further provides turbine fracturing equipment with the heat dissipation equipment. Multiple turbine fracturing apparatuses may be provided in a kit, for example, as shown in fig. 9, two turbine fracturing apparatuses may be provided side-by-side at the surface. Wherein a first turbine fracturing apparatus 200 of the two turbine fracturing apparatuses comprises a first engine 201 and a first heat sink 202 arranged at a gooseneck portion thereof, and a second turbine fracturing apparatus 300 comprises a second engine 301 and a second heat sink 302 arranged at a gooseneck portion thereof. The first heat sink 202 and the second heat sink 302 are the shelter heat sinks shown in fig. 1-7, so that the first heat sink 202 and the second heat sink 302 both draw in hot airflow from the side and exhaust the cooled airflow from the top, and the flow direction of the air drawn in is shown by arrows in fig. 9. It can be seen that, because the first heat dissipation device 202 and the second heat dissipation device 302 are air-breathing heat dissipation devices, when a plurality of turbine fracturing equipment operate side by side, the heat dissipation device of each turbine fracturing equipment cannot affect other heat dissipation devices, and higher operation efficiency in a limited operation space can be achieved.

The heat dissipation device provided by the invention is provided with a plurality of noise reduction means. The heat dissipation device can adjust the power of the gas guiding device according to the air inlet temperature, and can avoid energy waste and unnecessary noise. The heat dissipation device is internally provided with a noise reduction core body, and gas can flow through the outer surface of the noise reduction core body, so that the noise is further reduced on the premise of not influencing the gas flow. Moreover, the heat dissipation device is an air suction type heat dissipation device, when a plurality of turbine fracturing equipment works side by side, the heat dissipation device of each turbine fracturing equipment cannot influence other heat dissipation devices, and higher working efficiency in a limited working space can be realized.

It is not intended that the invention be limited to a single disclosed embodiment. As above, many alternatives and modifications of the present invention will be apparent to those of ordinary skill in the art in light of the above teachings.
