Description

Technical Field

[0001] This utility model relates to the field of oil pump cooling technology, and more specifically, to an oil pump cooling device. Background Technology

[0002] A pump is a machine that transports or pressurizes fluids. It transfers the mechanical energy of a prime mover or other external energy to the liquid, increasing the liquid's energy. Pumps are mainly used to transport liquids such as water, oil, acids and alkalis, emulsions, suspensions, and liquid metals. They can also transport liquid-gas mixtures and liquids containing suspended solids. Pumps are generally classified into three types according to their working principle: positive displacement pumps, dynamic pumps, and other types. Existing oil pumps, when transporting high-energy liquids, are prone to overheating, affecting the motor's lifespan. Furthermore, traditional oil pump motors have weak heat dissipation, leading to increased motor load and higher temperatures during pressurization, increasing rotor resistance and causing a continuous rise in internal motor temperature, potentially damaging the motor. Therefore, an oil pump cooling device is urgently needed. Utility Model Content

[0003] The purpose of this utility model is to provide an oil pump cooling device that uses coolant to exchange heat with the motor. The coolant has a long flow path, which increases the contact area and contact time with the motor, thereby enabling better heat exchange with the motor and improving the motor's heat dissipation effect.

[0004] The embodiments of this utility model are achieved through the following technical solutions:

[0005] An oil pump cooling device includes a motor and a pump housing disposed on one side of the motor. The outer surface of the pump housing is provided with an oil inlet and an oil outlet.

[0006] An isolation cover is installed inside the motor. The isolation cover is coaxially arranged with the motor, and a gap is left between the isolation cover and the inner side of the motor to form a cooling cavity. A cooling cylinder is also installed on the outside of the motor, and the cooling cylinder is connected to the cooling cavity. An isolation plate is arranged longitudinally inside the cooling cylinder, and the isolation plate divides the cooling cylinder into two independent cavities, left and right. A water inlet is provided on one side of the cooling cylinder and a water outlet is provided on the other side, and the water inlet and water outlet are respectively located on the left and right sides of the isolation plate.

[0007] Furthermore, the top of the isolation plate is connected to the top wall of the cooling cylinder, the bottom of the isolation plate is connected to the outer side of the cooling cavity, and the isolation plate divides the upper part of the cooling cavity into two independent cavities, left and right.

[0008] Furthermore, a sealing cover is provided at the end of the motor away from the pump box, the sealing cover has multiple ventilation holes, and a cooling fan is provided on one side of the sealing cover.

[0009] Furthermore, the inner wall of the sealing cover is provided with a plurality of heat dissipation strips along the circumference, the heat dissipation strips being elongated and inclined.

[0010] Furthermore, the heat dissipation strip is at an angle of 30 to 60° to the longitudinal section of the motor parallel to its central axis.

[0011] Furthermore, the cooling chamber is equipped with multiple baffles.

[0012] Furthermore, the connector at one end of the power cord of the motor is a quick connector.

[0013] The technical solution of this utility model embodiment has at least the following advantages and beneficial effects:

[0014] To achieve better heat dissipation for the motor, this invention features a cooling cylinder on the outside of the motor. An inlet is located on the left side of the cooling cylinder, and an outlet on the right side. Coolant can be introduced into the cooling cylinder through the inlet. Because the cooling cylinder is divided into two independent cavities by a partition plate, the coolant enters the cooling cavity from the left side, filling it from the left to the bottom and then flowing to the right until the cavity is full. This flow of coolant effectively cools the internal components of the motor, resulting in better heat dissipation. Once the cooling chamber is filled with coolant, it enters the right side of the cooling cylinder and flows out from the outlet on the right side of the cooling cylinder. At this point, heat exchange is completed, i.e., heat dissipation for the motor. More importantly, when the cooling cylinder and the inner trough of the cooling chamber are filled with coolant, the coolant flowing into the cooling cylinder from the inlet can still follow the path described above, from left to bottom and then to right, i.e., from high to low and then from low to high, and finally flows out from the outlet. The entire flow path of the coolant is relatively long, which increases the contact area and contact time with the motor, thereby enabling better heat exchange with the motor and improving the motor's heat dissipation effect.

[0020] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. The components of the embodiments of this utility model described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0021] Example 1

[0022] An oil pump cooling device includes a motor 2 and a pump housing 1 disposed on one side of the motor 2. The outer surface of the pump housing 1 is provided with an oil inlet 11 and an oil outlet 12.

[0023] An isolation cover 5 is provided inside the motor 2. The isolation cover 5 is coaxially arranged with the motor 2, and a gap is left between the isolation cover 5 and the inner side of the motor 2 to form a cooling cavity 6. A cooling cylinder 3 is also provided on the outside of the motor 2, and the cooling cylinder 3 is connected to the cooling cavity 6. An isolation plate 33 is arranged longitudinally inside the cooling cylinder 3, and the isolation plate 33 divides the cooling cylinder 3 into two independent cavities, left and right. A water inlet 31 is provided on one side of the cooling cylinder 3, and a water outlet 32 ​​is provided on the other side. The water inlet 31 and the water outlet 32 ​​are respectively located on the left and right sides of the isolation plate 33.

[0024] Working principle: To achieve better heat dissipation for motor 2, this invention includes a cooling cylinder 3 on the outside of motor 2, such as... Figure 1As shown, an inlet 31 is provided on the left side of the cooling cylinder 3, and an outlet 32 ​​is provided on the right side. Coolant can then be introduced into the cooling cylinder 3 through the inlet 31. Since the partition plate 33 inside the cooling cylinder 3 divides it into two independent cavities, the coolant entering the cooling cylinder 3 can flow into the cooling cavity 6 from the left side, filling the bottom of the cooling cavity 6 and then flowing to the right side until the cooling cavity 6 is full. During this flow, the coolant cools the inside of the motor 2, thus improving heat dissipation. After the cooling cavity 6 is filled with coolant... The coolant can then enter the right side of the cooling cylinder 3 and flow out from the outlet 32 ​​on the right side of the cooling cylinder 3, thus completing the heat exchange, i.e., cooling the motor 2. More importantly, after the cooling cylinder 3 and the cooling chamber 6 are filled with coolant, the coolant flowing into the cooling cylinder 3 through the inlet 31 can still follow the path described above, from left to bottom and then to right, i.e., from high to low and then from low to high, and finally flow out from the outlet 32. The entire flow path of the coolant is relatively long, which increases the contact area and contact time with the motor 2, thereby better exchanging heat with the motor 2 and improving the heat dissipation effect of the motor 2.

[0025] In this embodiment, the top of the isolation plate 33 is connected to the top wall of the cooling cylinder 3, and the bottom of the isolation plate 33 is connected to the outer side of the cooling cavity 6. The isolation plate 33 divides the upper part of the cooling cavity 6 into two independent cavities on the left and right. This ensures the separation and sealing between the isolation plate 33 and the cooling cylinder 3 and the cooling cavity 6, and ensures the independence of the left and right sides of the isolation plate 33. This allows the coolant to flow from the inlet 31 from high to low and then from low to high, and finally flow out from the outlet 32, thereby ensuring the heat exchange effect of the coolant on the motor 2.

[0026] In this embodiment, a sealing cover 21 is provided at the end of the motor 2 away from the pump box 1. The sealing cover 21 has multiple ventilation holes 23 and a cooling fan 4 is provided on one side of the sealing cover 21. This provides better heat dissipation for the motor 2 and can avoid or reduce the occurrence of motor 2 burning out due to heat dissipation problems.

[0027] In this embodiment, the inner wall of the sealing cover 21 is provided with a plurality of heat dissipation strips 22 along the circumference. The heat dissipation strips 22 are elongated and inclined. In this way, when the cooling fan 4 blows cold air into the motor 2, the airflow is turbulent due to the obstruction of the heat dissipation strips 22, thereby allowing the cooling air to be better dispersed inside the motor 2 and ensuring the cooling effect of the cooling air on the motor 2.

[0028] In this embodiment, the heat dissipation strip 22 is at an angle of 30 to 60° to the longitudinal section of the motor 2 parallel to the central axis; this creates a certain vortex under the turbulence of the cooling air, thereby making the heat dissipation effect on the motor 2 better.

[0029] In this embodiment, multiple baffles 7 are provided in the cooling chamber 6, which allows the coolant to have a longer flow path and flow time in the cooling chamber 6, thereby improving the heat exchange effect on the motor 2.

[0030] In this embodiment, the connector at one end of the power cord of the motor 2 is a quick connector, so that when replacing the oil pump, there is no need to rewire, which greatly saves replacement time.

[0031] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
