Description

Technical Field

[0001] This application relates to the field of radiator technology, and in particular to a radiator for fracturing vehicles. Background Technology

[0002] A fracturing truck is a specialized vehicle primarily used to inject high-pressure, high-volume fracturing fluid into wells to break up formations and force proppant into the fractures. It is widely used in various fracturing operations in oil wells, gas wells, and water wells. Additionally, it can be used for hydraulic sandblasting, high-pressure hydraulic coal mining, and high-pressure hydraulic rust removal on ships.

[0003] During the operation of a fracturing truck, the engine coolant and hydraulic oil in the hydraulic system generate a large amount of heat. To ensure the normal operation of the engine and hydraulic system, it is usually necessary to perform heat dissipation and cooling treatment on the engine coolant and hydraulic oil.

[0004] Currently, the radiators commonly used in fracturing trucks generally consist of a radiator frame, flow guide pipes, and a cooling fan. The radiator frames are stacked, and the flow guide pipes are installed in corresponding frames, through which the liquid to be cooled, such as engine coolant or hydraulic oil from the hydraulic system, flows. The cooling fan is installed at the bottom of the radiator. When running, the cooling fan directs external airflow from bottom to top through the multiple layers of radiator frames, where it contacts the flow guide pipes installed in the frames to exchange heat, thereby reducing the temperature of the liquid to be cooled.

[0005] However, in hot weather, the temperature of engine coolant or hydraulic oil in the hydraulic system can often reach 80°C or even higher, while the ambient temperature is generally between 40°C and 55°C. During gas flow, the relatively cooler airflow cools the high-temperature liquid in the guide tube. However, because the radiator has a layered structure, the airflow temperature gradually increases as it flows upward due to heat exchange, resulting in a smaller temperature difference between the airflow flowing to the upper layer of the radiator and the guide tube, thus reducing the heat dissipation effect.

[0006] Meanwhile, when the radiator operates in a windy and sandy environment, the sand can easily clog the heat sink frame, affecting the airflow speed. Because the radiator is arranged in a stacked manner, the airflow speed will decrease sharply when passing through the stacked clogged areas, further reducing the heat exchange efficiency.

[0007] Furthermore, the stacked structure of the radiator also makes maintenance inconvenient. When maintenance is needed, the entire radiator often needs to be disassembled, which undoubtedly affects maintenance efficiency. Utility Model Content

[0008] To further improve the heat dissipation effect of the radiator, this application provides a radiator for fracturing vehicles.

[0009] The technical solution for a fracturing vehicle radiator provided in this application is as follows:

[0010] A radiator for fracturing vehicles includes a heat dissipation frame, a guide pipe, and a gas diversion device, wherein:

[0011] The heat sink is arranged in a ring shape, with one end closed and the other end open;

[0012] The guide tube is disposed on the heat dissipation frame, and the liquid to be cooled is introduced into the guide tube;

[0013] The outlet of the gas diversion device is located near the opening of the heat sink.

[0014] Optionally, the heat sink includes a fixing frame and a mounting bracket, wherein:

[0015] Multiple mounting brackets are provided and are arranged circumferentially on a fixed frame along the outlet axis of the gas diversion device;

[0016] The flow guide tube is mounted on the mounting bracket.

[0023] Optionally, a connecting ring is formed between two adjacent mounting rings and two adjacent columns;

[0024] The mounting bracket is installed in the connecting ring;

[0030] Optionally, the placement rack is equipped with a protective net.

[0031] Optionally, the guide tubes are distributed in a single layer in the radial direction of the heat sink.

[0032] In summary, this application includes at least one of the following beneficial technical effects:

[0033] 1. The heat sink adopts a ring-shaped design, allowing airflow to directly exit after heat exchange with the guide tube. This structure increases the contact area between the guide tube and the airflow, improving the heat exchange effect. Even if some areas are blocked, airflow can still enter the heat sink from other unblocked areas for heat exchange, thus reducing the impact of blocked areas on the overall heat exchange effect;

[0034] 2. The airflow is arranged in a single radial layer on the heat sink, and the airflow is directly discharged after passing through the single layer of airflow. This design reduces the impact of the temperature rise of the airflow during heat exchange on the cooling effect of the airflow, thus improving the heat dissipation efficiency;

[0035] 3. The mounting bracket is detachably fixed to the fixed frame with bolts, facilitating the replacement of different models of mounting brackets or guide tubes according to different heat dissipation requirements. When a mounting bracket becomes clogged or requires maintenance, the bracket requiring repair can be directly removed without affecting the normal operation of other mounting brackets, improving maintenance efficiency. Furthermore, the openings of the heat dissipation bracket are equipped with protective mesh and filters, protecting the axial fan and guide tubes while blocking impurities in the airflow, reducing the impact of impurities on the normal operation of the equipment.

[0040] The following is in conjunction with the appendix Figures 1-2 This application will be described in further detail.

[0041] This application discloses a radiator for fracturing vehicles.

[0042] A radiator for a fracturing vehicle includes a heat dissipation frame 1, a guide pipe 2, and a gas diversion device. The heat dissipation frame 1 is installed on the fracturing vehicle and is arranged in a ring shape. One end of the heat dissipation frame 1 is closed, and the other end of the heat dissipation frame 1 has an opening. The guide pipe 2 is installed on the heat dissipation frame 1 and is filled with liquid to be cooled. The outlet of the gas diversion device is installed on the heat dissipation frame 1 near the opening.

[0043] When using the cooling frame 1, it is installed on the fracturing truck, and the liquid to be cooled, such as engine coolant or hydraulic oil from the hydraulic system, is introduced into the guide pipe 2, allowing the liquid to circulate within the guide pipe 2. A gas diversion device draws external airflow through the cooling frame 1, which then contacts the guide pipe 2 on the cooling frame 1 for heat exchange, thereby lowering the temperature of the liquid inside the guide pipe 2.

[0044] The heat sink 1 is arranged in a ring shape. After the airflow comes into contact with the guide pipe 2 for heat exchange, it is discharged directly from the opening of the heat sink 1. The ring shape of the heat sink 1 increases the contact area between the guide pipe 2 and the airflow, thus improving the heat exchange effect. Even if some areas are blocked, the airflow can enter the interior of the heat sink 1 from other unblocked areas to exchange heat and cool the guide pipe 2, thereby reducing the impact of the blocked areas on the heat exchange of the guide pipe 2 on the heat sink 1.

[0045] The guide pipes 2 are radially distributed in a single layer on the heat dissipation frame 1. After passing through the single layer of guide pipes 2, the airflow is directly discharged from the outlet of the heat dissipation frame 1, reducing the impact of the temperature rise after airflow temperature exchange on the cooling of the guide pipes 2. The heat dissipation frame 1 includes a fixed frame 11 and mounting brackets 12. The fixed frame 11 is arranged in a ring shape, and the bottom of the fixed frame 11 is closed. The closed section of the fixed frame 11 is installed on the fracturing vehicle. The gas diversion device is installed on the fixed frame 11. Multiple mounting brackets 12 are provided and fixedly installed on the fixed frame 11. The multiple mounting brackets 12 are arranged circumferentially on the fixed frame 11 along the outlet axis of the gas diversion device. The guide pipes 2 are pre-installed on the mounting brackets 12.

[0046] When assembling the heat sink 1, the guide pipe 2 is installed on the mounting bracket 12, and the mounting bracket 12 is installed on the heat sink 1. This allows for the replacement of different models of mounting bracket 12 or guide pipe 2 according to different heat dissipation requirements. The mounting bracket 12 is detachably fixed to the fixed frame 11 by bolts, thereby improving the convenience of disassembling and assembling the mounting bracket 12. When the mounting bracket 12 is blocked or needs maintenance, the mounting bracket 12 that needs to be disassembled can be directly disassembled and maintained without affecting the operation of other mounting brackets 12.

[0047] The guide tube 2 is installed on a single mounting bracket 12, which allows for the simultaneous dissipation of heat from multiple different liquids to be cooled, further improving heat dissipation efficiency. Furthermore, in practical use, adjacent guide tubes 2 can be connected to increase the movement distance of the same liquid within the guide tube 2, thereby increasing heat exchange time and ultimately enhancing the cooling effect on the liquid.

[0048] The heat sink bracket 1 includes mounting rings 111 and uprights 112. There is a pair of mounting rings 111, coaxially arranged. Multiple uprights 112 are positioned between the two mounting rings 111, arranged along the axis of the mounting rings 111. Each upright 112 is fixedly connected at both ends to an adjacent mounting ring 111. A connecting ring is formed between two adjacent uprights 112 and the mounting rings 111. The mounting bracket 12 is located within the connecting ring and fixedly connected to it. The connecting ring positions the mounting bracket 12, improving the ease of installation.

[0049] The gas diversion device can be a gas inlet pipe that drives the flow of surrounding gas through the negative pressure ejected from the outlet, or it can be an axial flow fan 4, etc. In this embodiment, the gas diversion device is an axial flow fan 4. To protect the axial flow fan 4 and the personnel, a placement rack 3 is provided at the opening of the heat sink 1. The axial flow fan 4 is mounted on the placement rack 3, which is equipped with a protective net 5 for protection. To facilitate the protection of the guide pipe 2 on the mounting frame 12, a filter screen 121 is provided on the mounting frame 12. The filter screen 121 ensures airflow while protecting the guide pipe 2 and blocking impurities in the airflow, reducing the possibility that impurities passing through the axial flow fan 4 will hinder its normal operation.

[0050] The implementation principle of a radiator for a fracturing vehicle according to an embodiment of this application is as follows: First, a radiator frame 1 is installed on the fracturing vehicle. The frame is annular in shape, closed at one end and open at the other. A guide pipe 2 is installed on the radiator frame 1 and a liquid to be cooled (such as engine coolant or hydraulic oil in a hydraulic system) is introduced through it. The outlet of a gas diversion device is installed near the opening of the radiator frame 1. During operation, the gas diversion device guides external airflow through the radiator frame 1. After heat exchange with the guide pipe 2, the airflow is directly discharged from the opening of the radiator frame 1. The annular shape of the radiator frame 1 increases the contact area between the guide pipe 2 and the airflow, improving the heat exchange effect. Even if some areas are blocked, the airflow can enter the radiator frame 1 from other unblocked areas to exchange heat and cool the guide pipe 2, reducing the impact of blockage on heat exchange. Furthermore, the guide pipes 2 are radially distributed in a single layer on the radiator frame 1. The airflow is directly discharged after passing through the single layer of guide pipes 2, reducing the impact of increased airflow temperature on the cooling of the guide pipe 2.

[0051] The above are all preferred embodiments of this application and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
