Abstract

This utility model relates to the field of oil pump motors, specifically to an oil pump motor with heat dissipation and cooling capabilities. The motor is centered around a base and a cooling cover. The base is positioned to avoid the air outlet and fan of the motor body, allowing for the directional introduction of low-temperature airflow. The cooling cover, constructed from a quarter-circular cover and a U-shaped cover, contains a space to accommodate circulating cooling medium. Made of a high thermal conductivity material, it is hinged to the base to flexibly cover the motor body and is positioned above the air outlet. Together, the airflow passes through, facilitating faster heat transfer from the motor casing to the surface of the cooling cover. Simultaneously, the cooling medium within the cooling cover absorbs heat, reheats, and then circulates back to its original low temperature. Through the dual effects of "accelerated heat exchange via airflow + efficient heat absorption by the cooling medium," heat around the motor body is rapidly transferred to the cooling medium, effectively preventing heat accumulation around the motor and ensuring that the motor body remains within a safe operating temperature range, significantly improving the stability and lifespan of the motor.

Description

Technical Field

[0001] This utility model relates to the field of oil pump motors, and in particular to an oil pump motor that can dissipate heat and reduce temperature. Background Technology

[0002] In industrial production, oil pump motors, as key power equipment, are widely used in various industries such as petroleum, chemical, and machinery manufacturing. Their operational stability and service life directly affect overall production efficiency. However, when oil pump motors operate under long-term, high-load conditions, the motor body continuously generates a large amount of heat. If this heat cannot be dissipated effectively in a timely manner, the internal temperature of the motor will rise sharply.

[0003] Currently, most oil pump motors on the market have relatively simple heat dissipation structures, generally relying on natural heat dissipation from the motor's own casing or forced air cooling by a single fan. Natural heat dissipation is extremely inefficient and struggles to handle the large amounts of heat generated during high-load operation, easily causing the motor temperature to exceed limits. This can lead to problems such as decreased insulation performance and accelerated winding aging, and in severe cases, even motor burnout, affecting production processes. While forced air cooling by a single fan can improve heat dissipation to some extent, the fan outlet often blows directly onto the motor body, easily causing localized temperature fluctuations. Furthermore, it lacks a heat dissipation design that works in conjunction with the cooling medium, failing to form a comprehensive and efficient heat dissipation system that cannot meet the heat dissipation requirements of oil pump motors under different operating conditions. Summary of the Invention

[0004] In view of the shortcomings mentioned above in the background technology, this utility model provides an oil pump motor that can dissipate heat and reduce temperature.

[0005] The present invention adopts the following technical solution: A heat-dissipating and cooling oil pump motor, characterized in that the oil pump motor comprises: A base for mounting the motor body and having an air outlet; The cooling cover is composed of a quarter-circular cover and a U-shaped cover. The interior of the cooling cover is hollow to form a accommodating space for holding the cooling medium. It is provided with an opening and an outlet communicating with the accommodating space for circulating the cooling medium. The other end of the quarter-circular cover is hinged to the base and can be rotated downwards to cover the outside of the motor body, located above the air outlet. It uses the air outlet to promote airflow and enhance heat dissipation. The cooling cover is made of a material with a high thermal conductivity.

[0006] As a further improvement, the cooling medium is preferably water.

[0007] As a further improvement, a fan is provided in the mounting slot of the base to supply air to the air outlet.

[0008] As a further improvement, the cooling cover is made of metal.

[0009] As a further improvement, a first magnetic block is provided on the bottom surface of the cooling cover, and a second magnetic block is provided on the upper surface of the base. The second magnetic block and the first magnetic block are magnetically attracted to each other.

[0010] As a further improvement, the base and the cooling cover are hinged together.

[0011] As described above, this utility model has the following advantages compared to existing technologies: It constructs a synergistic heat dissipation system with a base and a cooling cover as its core. The base is positioned to avoid the motor body's air outlet and fan, allowing for the directional introduction of low-temperature airflow. The cooling cover, composed of a quarter-circular cover and a U-shaped cover, has a space to accommodate the circulating cooling medium. Made of a high thermal conductivity material, it is hinged to the base to flexibly cover the motor body and is positioned above the air outlet. The combination of these two components allows airflow to pass through, facilitating faster heat transfer from the motor casing to the cooling cover surface. Simultaneously, the cooling medium inside the cooling cover absorbs heat, reheats, and then circulates back to a low temperature. Through the dual effects of "accelerated heat exchange via airflow + efficient heat absorption by the cooling medium," heat around the motor body is rapidly transferred to the cooling medium, effectively preventing heat accumulation around the motor and ensuring that the motor body remains within a safe operating temperature range, significantly improving the stability and service life of the motor. This comprehensively meets the heat dissipation needs of the oil pump motor under different operating conditions, ensuring stable motor operation. Attached Figure Description

[0016] The specific embodiments of this utility model are described below with reference to the accompanying drawings.

[0017] As attached Figure 1 As shown, a heat-dissipating and cooling oil pump motor has a core structure including a base 1 and a cooling cover 3. The two work together to build an efficient and reliable heat dissipation system, which fully meets the heat dissipation requirements of the oil pump motor under different operating conditions.

[0018] The base 1, as the fundamental support component of the entire oil pump motor, not only bears the important responsibility of mounting the motor body 2, but also provides crucial protection for the operation of the heat dissipation system. It is constructed entirely of high-strength alloy material, possessing excellent load-bearing capacity and deformation resistance, stably supporting the weight of the motor body 2 while effectively resisting vibration and impact in the industrial environment, ensuring the stability of the oil pump motor during operation.

[0019] As attached Figure 1 and Figure 4 As shown, in terms of heat dissipation design, the base 1 is carefully designed with an air outlet 11, and the position of the air outlet 11 has been precisely calculated to cleverly avoid the motor body 2. This design not only avoids the local temperature fluctuations that may be caused by the air outlet 11 blowing directly on the motor body 2, but also ensures that the airflow is smooth and unobstructed to the subsequent heat dissipation components, laying a good foundation for the entire heat dissipation process.

[0020] More importantly, a dedicated fan is installed within the mounting slot 12 of the base 1. This fan is an industrial-grade, high-efficiency, quiet fan, boasting advantages such as large air volume, stable air pressure, low operating noise, and long service life. The fan's outlet is precisely aligned with the outlet 11 on the base 1, forming a directional airflow channel. When the fan starts, it quickly draws in low-temperature outside air, guides it through the internal air duct, and stably discharges it through the outlet 11. This provides continuous and sufficient airflow support for the subsequent heat dissipation of the cooling cover 3, accelerating the dissipation of heat around the motor body 2 and effectively controlling the temperature of the motor body 2.

[0021] As attached Figure 2 As shown, the cooling cover 3 is the core component of the oil pump motor cooling system. Its unique structural design and high-quality material selection give it excellent heat dissipation performance. The cooling cover 3 is composed of a quarter-circular cover 3a and a U-shaped cover 3b. This splicing structure not only facilitates manufacturing and assembly but also fully covers the motor body 2 according to its shape, ensuring maximum heat dissipation area. Precision welding is used at the splicing points, resulting in smooth and strong welds that effectively prevent cooling medium leakage and ensure the sealing performance of the cooling cover 3.

[0022] The cooling cover 3 has a hollow interior forming a accommodating space 34. The volume of this accommodating space 34 is scientifically calculated to hold a sufficient amount of cooling medium, providing ample cooling resources for the heat dissipation of the motor body 2. The inner wall of the accommodating space 34 undergoes special anti-corrosion treatment, effectively resisting the corrosion of the cooling medium and extending the service life of the cooling cover 3. Simultaneously, the cooling cover 3 has an opening 33 and an outlet communicating with the accommodating space 34 for circulating the cooling medium. Specifically, the opening 33 and outlet are connected to an external circulation pump, constructing a cooling medium circulation system. The circulation pump is an industrial-grade corrosion-resistant circulation pump, possessing advantages such as stable flow rate, suitable head, and reliable operation. When the circulation system starts, the circulation pump draws the cooling medium from the bottom outlet of the cooling cover 3, cools it through an external cooling device (such as a cooling water tank or cooler), and then reinjects it into the accommodating space 34 of the cooling cover 3 through the top opening 33, achieving the recycling of the cooling medium. This circulating design ensures that the cooling medium remains at a low temperature, continuously and efficiently absorbing the heat emitted by the motor body 2, significantly improving the cooling effect, and ensuring that the temperature of the motor body 2 is always controlled within a safe range under long-term, high-load operation, effectively avoiding motor failure caused by excessive temperature and ensuring stable operation of the equipment.

[0023] For the selection of cooling medium, water is preferred for the oil pump motor. Water has significant advantages such as high specific heat capacity, good thermal conductivity, low cost, and easy availability. It can efficiently absorb the heat dissipated by the motor body 2 and quickly reduce the motor temperature. Moreover, water is environmentally friendly and pollution-free during use, meeting the requirements of modern industrial green production. Of course, other types of cooling media, such as special coolants, can also be selected according to different operating environments and temperature requirements. The design of the cooling cover 3 has a certain degree of compatibility and can meet the needs of different cooling media.

[0024] As attached Figure 2 and Figure 4As shown, the other end of the quarter-circular cover 3a is hinged to the base 1 via a hinge 32. This connection allows the quarter-circular cover 3a to rotate flexibly downwards, thereby causing the entire cooling cover 3 to cover the outside of the motor body 2. At the same time, it ensures that the cooling cover 3 is directly above the air outlet 11 of the base 1, forming a preset airflow path. This positional arrangement allows the airflow discharged from the air outlet 11 of the base 1 to act directly on the outer surface of the cooling cover 3 without detour. After contacting the surface of the cooling cover 3, the airflow will flow rapidly along the curvature of the cover, accelerating the renewal and circulation of air on the surface of the cover and carrying away the hot air that has absorbed heat in time. On the other hand, the continuous impact of the airflow can also break the stagnant hot air layer formed on the surface of the cooling cover 3, reduce thermal resistance, and further improve the heat dissipation efficiency.

[0025] When the oil pump motor starts running, the motor body 2 continuously generates heat due to electromagnetic induction, mechanical friction, and other factors. This heat diffuses outward through the motor casing via thermal conduction and radiation. At this time, the low-temperature airflow discharged from the outlet 11 quickly passes through the gap between the cooling cover 3 and the base 1, blowing air between the motor casing and the inner wall of the cooling cover 3, accelerating the convection exchange between the hot air and the low-temperature airflow in this area, and promoting faster heat transfer from the motor casing to the surface of the cooling cover 3. Simultaneously, the cooling medium (such as water or a special coolant) filled in the internal space 34 of the cooling cover 3 absorbs heat through the highly thermally conductive wall surface of the cooling cover 3, raising its own temperature. The heated cooling medium is then circulated by the circulation pump to return to its original low temperature, ensuring effective heat absorption. Through the dual effects of "accelerated heat exchange via airflow + efficient heat absorption by the cooling medium," the heat around the motor body 2 is rapidly transferred to the cooling medium, effectively preventing heat accumulation around the motor and ensuring that the motor body 2 remains within a safe operating temperature range, significantly improving the stability and service life of the motor.

[0026] The cooling cover 3 is made of a metal with high thermal conductivity, specifically pure aluminum or aluminum alloy. Pure aluminum has extremely high thermal conductivity, which can quickly conduct the heat transferred from the motor body 2 to the internal cooling medium; while aluminum alloy, while ensuring high thermal conductivity, also has greater hardness and corrosion resistance, making it suitable for harsher industrial environments. Whether made of pure aluminum or aluminum alloy, the cooling cover 3 ensures excellent thermal conductivity, providing a strong guarantee for efficient heat dissipation.

[0027] As attached Figure 1 and Figure 3As shown, to ensure the stability of the cooling cover 3 when it covers the outside of the motor body 2, and to prevent the cooling cover 3 from shifting due to equipment vibration and other factors, thus affecting the heat dissipation effect, a first magnetic block 31 is provided on the bottom surface of the cooling cover 3, and a second magnetic block 13 is provided on the upper surface of the base 1. The second magnetic block 13 is magnetically attracted to the first magnetic block 31. Both the first magnetic block 31 and the second magnetic block 13 are high-strength permanent magnets, which have the characteristics of strong magnetism, stable magnetic force, and long service life. When the cooling cover 3 covers the outside of the motor body 2, the first magnetic block 31 and the second magnetic block 13 are precisely aligned and tightly attracted, firmly fixing the cooling cover 3 to the base 1, effectively preventing the cooling cover 3 from loosening or shifting during motor operation, and ensuring the stable operation of the heat dissipation system.

[0028] As attached Figure 3 As shown, in actual use, to avoid affecting the normal operation of the motor body 2, when the cooling cover 3 is placed over the outside of the motor body 2, the oil port 21 of the oil pump on the motor body 2 is exposed through the cooling cover 3. The oil port 21 is an important interface for the oil pump to inject and discharge oil. Its exposed design ensures that operators can easily perform oil-related operations without disassembling the cooling cover 3, greatly improving the ease of use and maintenance efficiency of the equipment, and reducing production downtime caused by cumbersome operations.

[0029] In terms of equipment maintenance and repair, the oil pump motor also features a user-friendly design. The base 1 and the cooling cover 3 are hinged together by a hinge 32. The hinge 32 is made of high-strength stainless steel, which has the characteristics of strong load-bearing capacity, flexible rotation, wear resistance, and corrosion resistance. This ensures that the connection between the base 1 and the cooling cover 3 is firm and reliable, while also ensuring the flexibility of the cooling cover 3 to rotate, making it easy for operators to open the cooling cover 3 to perform maintenance and repair work on the motor body 2.

[0030] Of particular note is that a first magnetic block 31 and a second magnetic block 13 are embedded in the two metal blades of the hinge 32, respectively. When the motor body 2 needs maintenance, the operator only needs to rotate the cooling cover 3 upwards. When the two metal blades of the hinge 32 overlap, the first magnetic block 31 and the second magnetic block 13 on the two metal blades will quickly magnetically engage. This magnetic engagement design can firmly fix the opened cooling cover 3 in its current position, greatly improving the stability of the cooling cover 3 during maintenance and effectively reducing the risk of the cooling cover 3 rotating downwards due to accidental force during maintenance. This provides the operator with a safe and stable maintenance work space, making it easier for the operator to complete the maintenance of the motor body 2 more efficiently and safely, and reducing safety hazards during maintenance.

[0031] In summary, this utility model constructs a collaborative heat dissipation system with the base 1 and the cooling cover 3 as its core. The base 1 is designed to avoid the air outlet 11 and fan of the motor body 2, allowing for the directional introduction of low-temperature airflow. The cooling cover 3 is composed of a quarter-circular cover 3a and a U-shaped cover 3b, with a accommodating space 34 to hold the circulating cooling medium. It is made of a material with high thermal conductivity and is hinged to the base 1 to flexibly cover the motor body 2 and is located above the air outlet 11. Together, the airflow passes through, facilitating the faster transfer of heat from the motor casing to the surface of the cooling cover 3. Simultaneously, the cooling medium inside the cooling cover 3 absorbs heat, reheats, and then circulates back to a low temperature. Through the dual effects of "accelerated heat exchange by airflow + efficient heat absorption by the cooling medium," the heat around the motor body 2 is rapidly transferred to the cooling medium, effectively preventing heat accumulation around the motor and ensuring that the motor body 2 remains within a safe operating temperature range, significantly improving the stability and service life of the motor. This comprehensively meets the heat dissipation needs of the oil pump motor under different operating conditions, ensuring stable motor operation.

[0032] The above are merely specific embodiments of this utility model, but the design concept of this utility model is not limited thereto. Any non-substantial modifications made to this utility model using this concept shall be considered as an infringement of the protection scope of this utility model.
