Description

Technical Field

[0001] This application relates to the field of deep geological drilling technology, specifically to a top-drive heat dissipation device with dual-fan circulating heat dissipation. Background Technology

[0002] With the development of electric motor technology, electric motors generate more and more heat, requiring cooling devices with larger heat exchange capacities to cool down the motors, prevent overheating failures, and ensure the service life of the motors.

[0003] Traditional top-drive cooling devices typically use a single fan for heat dissipation, usually installed at the air inlet or outlet of the motor. However, the air circulation speed is relatively slow. Inside the motor, heat transfer mainly relies on natural air convection and a small amount of cool air blown in by the fan. This cooling method can work normally when the motor load is light and the heat generation is not large. However, under high load and long-term operation, the heat accumulation inside the motor may cause the temperature to rise too quickly, and the heat dissipation efficiency may not meet the requirements.

[0004] In addition, the installation and disassembly of the top drive cooling device are laborious and time-consuming, and maintenance is inconvenient. Once a fault occurs, it is difficult to quickly inspect and troubleshoot. Utility Model Content

[0005] Therefore, this application provides a top drive cooling device with dual fan circulation cooling to solve the problem of low cooling efficiency in traditional top drive cooling devices that use a single fan for cooling.

[0006] To achieve the above objectives, this application provides the following technical solution:

[0007] A top-drive cooling device with dual-fan circulating heat dissipation includes a chassis, an electric motor installed inside the chassis, an air inlet on one side of the chassis, and an air outlet on the other side of the chassis corresponding to the position opposite to the air inlet, with the air outlet and air inlet distributed diagonally; the air inlet is connected to a blower through a first air supply channel, and the air outlet is connected to an exhaust fan through a second air supply channel.

[0008] Optionally, the air inlet is located at the lower front of the left side of the chassis, the air outlet is located at the upper rear of the right side of the chassis, the blower is located at the front of the upper part of the chassis, and the exhaust fan is located at the rear of the upper part of the chassis.

[0009] Optionally, the chassis is divided into a first cover plate at the bottom, a main body in the middle, and a second cover plate at the top, and the main body is detachably connected to the first cover plate and the second cover plate respectively.

[0017] 1. Based on further analysis and research of existing technical problems, this application provides a top-drive cooling device with dual-fan circulating heat dissipation. The overall structure is simple and the design is reasonable. It adopts a dual-fan system, with one fan for supplying air and the other for exhausting air, ensuring rapid air renewal and circulation inside the motor, accelerating heat dissipation. At the same time, the exhaust volume of the two fans is the same as the supply volume, avoiding the formation of positive or negative pressure inside the motor, improving the motor's heat dissipation efficiency, reducing the motor's operating temperature, improving the stability and reliability of the cooling system, preventing the motor from overheating, and extending the motor's service life. In addition, the diagonal air supply and exhaust duct design allows the cool air to fully contact the heat-generating components, reducing the existence of heat dissipation dead zones and further improving heat dissipation efficiency.

It adopts a modular design, which facilitates quick installation and disassembly, allows for rapid inspection of the internal condition, and facilitates the maintenance of internal components. It not only makes operation more flexible but also reduces the overall difficulty of disassembly and assembly, significantly improving the efficiency of installation and disassembly. The cover plate and the main chassis are also equipped with removable grilles, which serve to prevent dust and dissipate heat, further improving the convenience of maintenance. It is convenient to troubleshoot the motor inside the chassis without disassembling other parts, greatly simplifying the maintenance process.

[0019] 3. A temperature sensor is installed at the motor of this application to realize real-time monitoring of the motor's operating temperature and feed the temperature signal back to the controller.

[0034] The present application will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0035] In the description of this application: unless otherwise stated, "a plurality of" means two or more. The terms "first," "second," "third," etc., in this application are intended to distinguish the objects referred to and do not have any special meaning in terms of technical connotation (e.g., they should not be construed as an emphasis on importance or order). Expressions such as "comprising," "including," and "having" also mean "not limited to" (certain units, components, materials, steps, etc.).

[0036] The terms used in this application, such as "upper," "lower," "left," "right," and "middle," are generally used to indicate the general relative positional relationship for the purpose of intuitive understanding by referring to the accompanying drawings, and are not absolute limitations on the positional relationship in the actual product.

[0037] One embodiment of this application, such as Figures 1-7 As shown, a top-drive cooling device with dual-fan circulating heat dissipation includes a chassis 1. An electric motor 2 is installed inside the chassis 1. An air inlet 104 is provided on one side of the chassis 1, and an air outlet 105 is provided on the other side of the chassis 1, corresponding to the position opposite to the air inlet 104. The air outlet 105 and the air inlet 104 are diagonally distributed. The air inlet 104 is connected to a blower 3 through a first air supply channel 5, and the air outlet 105 is connected to an exhaust fan 4 through a second air supply channel 6. Under the action of the blower 3, cold air from the outside is blown into the interior of the chassis 1 through the first air supply channel 5. After being heated, the cold air rises naturally and is drawn out by the exhaust fan 4 installed at the air outlet 105 through the second air supply channel 6 and released to the outside.

[0038] The above embodiment employs a dual-fan system. With a supply fan 3 and an exhaust fan 4, one supplies air and the other exhausts it. The supply fan 3 delivers cool air into the motor 2, while the exhaust fan extracts hot air from the motor 2, forming a forced convection air circulation system. This ensures rapid air renewal inside the motor 2, accelerates heat dissipation, and prevents overheating. Simultaneously, the dual-fan system utilizes the combined action of the exhaust fan 4 and the supply fan 3. By precisely controlling the airflow of both fans, the exhaust volume is equal to the supply volume, preventing the formation of positive or negative pressure. Compared to traditional single-fan cooling, this application adds… The increased air circulation speed within the air unit (i.e., chassis 1) enhances the heat dissipation efficiency of the motor 2, thereby improving the stability and reliability of the cooling system. The diagonal air supply and exhaust port design of the air outlet 105 and air inlet 104 allows for a longer airflow path within the cooling device, enabling sufficient contact with the heat-generating components (i.e., motor 2) and absorption of heat, reducing the existence of heat dissipation dead zones. This ensures that the air has enough time and distance to exchange heat when flowing through the motor 2, improving heat dissipation efficiency. This top-drive cooling device can also better adapt to the high-power, high-heat-generating motor 2, ensuring the heat dissipation performance of the motor 2 during efficient operation.

[0039] Preferably, the air inlet 104 is located at the lower front of the left side of the chassis 1, and the air outlet 105 is located at the upper rear of the right side of the chassis 1; the blower 3 is located at the front of the upper part of the chassis 1 and is used to send cooling air into the chassis 1 from the air inlet 104; the exhaust fan 4 is located at the rear of the upper part of the chassis 1 and is used to extract the heated air from the inside of the chassis 1 and discharge it through the air outlet 105.

[0040] Preferably, the chassis 1 is divided into a first cover plate 102 at the bottom, a main body 101 in the middle, and a second cover plate 103 at the top. The main body 101 is detachably connected to the first cover plate 102 and the second cover plate 103 respectively. The air inlet 104 and the air outlet 105 are respectively disposed on the first cover plate 102 and the second cover plate 103.

[0041] More preferably, the outer walls of the main housing 101, the first cover plate 102, and the second cover plate 103 are all detachably connected with grilles 7.

[0042] More preferably, such as Figure 7 As shown, the main housing 101 is connected to the first cover plate 102 and the second cover plate 103 by the first screw 8 and the second screw 9 respectively; the main housing 101, the first cover plate 102 and the second cover plate 103 are respectively connected to the corresponding grille 7 by multiple third screws 10, wherein the grille 7 provided on the main housing 101 is not shown in the figure.

[0043] The main body 101 of the chassis 1 has two cover plates that are detachably connected to both sides by screws. This design allows for quick installation and disassembly of the modules. By removing the cover plates, the internal condition can be quickly checked, making it convenient to inspect the internal components. This not only makes the operation more flexible but also reduces the overall difficulty of disassembly and assembly, significantly improving the efficiency of installation and disassembly.

[0044] The cover plate and the main housing 101 are also equipped with a grille 7, which is quickly fixed with four screws. The top drive motor 2 is located below the grille 7. The grille 7 not only serves to prevent dust and dissipate heat, protecting the motor 2 from dust and impurities and ensuring good heat dissipation, but also further improves the convenience of maintenance. If the motor 2 malfunctions, the grille 7 can be opened directly during maintenance to troubleshoot the motor 2 inside the housing 1 without disassembling other parts, which greatly simplifies the maintenance process.

[0045] Preferably, a temperature sensor is installed at the motor 2, which is used to monitor the actual operating temperature of the motor 2;

[0046] The output of the temperature sensor is connected to the input of the controller. The two outputs of the controller are connected to the inputs of the blower 3 and the exhaust fan 4 respectively. The blower 3 and the exhaust fan 4 (dual blowers) can adjust the wind speed according to the required cooling requirements to optimize energy consumption and heat dissipation efficiency.

[0047] The temperature sensor enables real-time monitoring of the operating temperature of motor 2 and feeds the temperature signal back to the controller. The controller controls the power of the blower 3 and exhaust fan 4 based on the current temperature. When the temperature of motor 2 is higher than the optimal operating temperature, the controller controls the fan and increases its power and speed to achieve faster air circulation in the air jacket, effectively preventing motor 2 from overheating, improving the working efficiency of the fan, and reducing energy loss.

[0048] Preferably, both the exhaust fan 4 and the blower 3 are centrifugal fans.

[0049] The operating principle of the above embodiments:

[0050] The system employs a dual-fan design, with both an exhaust fan 4 and an exhaust fan 3 working together. The exhaust fan 3 draws in outside cold air, which then enters the air inlet 104 (air outlet) of the casing 1 through the first air supply channel 5 to dissipate heat from the motor 2 inside the casing 1. After exchanging heat with the motor 2, the temperature of the cold air rises and spontaneously rises to the air outlet 105, where it is then drawn out by the exhaust fan 4 through the second air supply channel 6 and discharged to the outside.

[0051] The top drive cooling device provided in this application can be fixed to the top drive platform 11 using four diagonally distributed bolts 12 during installation. After installation, the top drive device appears as follows: Figures 8-11 As shown.

[0052] The technical features of the above embodiments can be combined in any way (as long as there is no contradiction in the combination of these technical features). For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described; these embodiments not explicitly written should also be considered to be within the scope of this specification.
