Abstract
Description
Technical Field
[0001] This utility model belongs to the technical field of oil pump housings, and specifically relates to an oil pump housing that facilitates heat dissipation. Background Technology
[0002] An oil pump is a lightweight and compact pump primarily used for transporting oily media, such as gasoline, kerosene, and diesel. Currently, the power drive motor of an oil pump is covered by a cooling cap. Typically, the motor has a shaft at one end, while the other side, inside the cooling cap, houses a fan that rotates with the rotor for cooling. Oil pumps come in various types, including inline, distribution, and monocoque types, and are usually made of stainless steel or cast iron. Different types of oil pumps may differ in structure, but their basic principles are similar; both require a power source to operate, typically an engine crankshaft gear driving a camshaft at its lower part.
[0003] The existing cooling housing of the oil pump drive motor relies on cooling fans and heat dissipation holes for cooling, which is generally inefficient. Especially in hot seasons, the high airflow temperature will further reduce the cooling effect. At this time, the high temperature generated by the continuous operation of the oil pump is difficult to dissipate, which will affect the service life. Therefore, there is a need for an oil pump housing that can facilitate heat dissipation to solve the problems existing in the current technology. Utility Model Content
[0004] The purpose of this invention is to provide an oil pump housing that facilitates heat dissipation, thereby solving the problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution: an oil pump housing for easy heat dissipation, including a rear end housing of the machine body, a protective cavity is provided inside the rear end housing of the machine body, and a water injection cooling mechanism is sleeved on the outside of the rear end housing of the machine body. The water injection cooling mechanism includes a first annular baffle, a second annular baffle, and a water storage cooling shell. The first annular baffle is sleeved and fixed on the side surface of the rear end housing of the machine body, and the second annular baffle is also sleeved and fixed on the side surface of the rear end housing of the machine body. The water storage cooling shell is rotatably connected to the outside of the rear end housing of the machine body. Through the water injection cooling mechanism, water is injected into the water storage tank of the water storage cooling shell from the water injection pipe, thus constructing a water storage layer between the rear end housing of the machine body and the water storage cooling shell to achieve the effect of water cooling.
[0006] A connecting arm is fixed to one end face of the water storage cooling shell. The end of the connecting arm away from the water storage cooling shell is provided with a connector that is compatible with the cooling fan at the rear end of the motor shaft. Through the connecting arm, connector, water storage cooling shell and deflector plate, when the oil pump motor is working, the cooling fan and water storage cooling shell can be combined to form a rotating structure that follows the rotation of the motor shaft. During the rotation, the water storage cooling shell and the deflector plate arranged on its inner wall can agitate the cooling water, which can improve the fluidity of the cooling water and promote uniform flushing of the rear end shell of the machine body for efficient heat conduction.
[0007] It should be noted in the solution that the water storage cooling shell is provided with a water storage tank inside, and a water deflector is fixed on the inner ring wall of the water storage cooling shell.
[0008] It is worth noting that a water injection pipe is fixed to the side surface of the water storage cooling shell, and a water inlet is provided inside the water injection pipe.
[0009] Furthermore, it should be noted that the upper end of the water injection pipe is threaded with a sealing plug, and the water inlet of the water injection pipe is connected to the water storage tank of the water storage cooling shell.
[0010] In a preferred embodiment, a rotating seat is embedded and fixed at the center of the rear end face of the rear end shell of the machine body, and the connecting arm is rotatably connected to the rotating seat.
[0011] In a preferred embodiment, the side surface of the rear end shell of the body is provided with mounting holes, and the rear end of the rear end shell of the body is provided with heat dissipation holes.
[0012] Compared with the prior art, the oil pump housing provided by this utility model, which facilitates heat dissipation, has at least the following beneficial effects:
[0013] Water is injected into the water storage tank of the water storage shell through the water injection pipe by the water injection pipe, thus creating a water storage layer between the rear shell of the machine body and the water storage cooling shell to achieve the effect of water cooling.
[0014] By using a connecting swing arm, a docking joint, a water storage cooling shell, and a water deflector, the cooling fan and the water storage cooling shell can be combined to form a rotating structure that rotates with the motor shaft when the oil pump motor is working. During the rotation, the water storage cooling shell and the water deflector arranged on its inner wall can agitate the cooling water, which can improve the fluidity of the cooling water and promote even flushing of the rear shell of the machine body for efficient heat conduction.

Detailed Implementation
[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] Please see Figure 1-4 This utility model provides an oil pump housing that facilitates heat dissipation, including a rear end shell 1 of the machine body. The rear end shell 1 of the machine body has a protective cavity 2 inside. The rear end shell 1 of the machine body is fitted with a water injection cooling mechanism on the outside. The water injection cooling mechanism includes a first annular baffle 6, a second annular baffle 7 and a water storage cooling shell 9. The first annular baffle 6 is fitted and fixed on the side surface of the rear end shell 1 of the machine body, and the second annular baffle 7 is also fitted and fixed on the side surface of the rear end shell 1 of the machine body. The water storage cooling shell 9 is rotatably connected to the outside of the rear end shell 1 of the machine body. A connecting arm 12 is fixed on one end face of the water storage cooling shell 9. The end of the connecting arm 12 away from the water storage cooling shell 9 is provided with a connector 13 that is adapted to engage with the cooling fan at the rear end of the motor shaft.
[0022] Further as Figure 1 , Figure 2 and Figure 3 As shown, it is worth noting that the water storage cooling shell 9 has a water storage tank 11 inside, and a water deflector 10 is fixed on the inner ring wall of the water storage cooling shell 9.
[0023] Further as Figure 3 As shown, it is worth noting that a water injection pipe 14 is fixed on the side surface of the water storage cooling shell 9, and a water inlet 15 is provided inside the water injection pipe 14.
[0024] The solution has the following working process: Before use, the rear end shell 1 of the machine body is fitted and fixed to the rear end shaft of the oil pump motor and the outside of the cooling fan. Then, the sealing plug 8 is unscrewed from the water injection pipe 14. Water is then injected into the water storage tank 11 of the water storage cooling shell 9 from the water injection pipe 14. In this way, a water storage layer is built between the rear end shell 1 of the machine body and the water storage cooling shell 9 to achieve the effect of water cooling.
[0025] According to the above working process, water is injected into the water storage tank 11 of the water storage cooling shell 9 from the water injection pipe 14, thus creating a water storage layer between the rear shell 1 of the machine body and the water storage cooling shell 9 to achieve the effect of water cooling.
[0026] Further as Figure 1 , Figure 2 and Figure 4 As shown, it is worth noting that the upper end of the water injection pipe 14 is threaded with a sealing plug 8, and the water inlet 15 of the water injection pipe 14 is connected to the water storage tank 11 of the water storage cooling shell 9.
[0027] Further as Figure 4 As shown, it is worth noting that a rotating seat 5 is embedded and fixed at the center of the rear end face of the rear end shell 1 of the machine body. The connecting arm 12 is rotatably connected to the rotating seat 5. When the oil pump motor is working, the rear end shaft of the motor drives the cooling fan to rotate and perform heat dissipation. The connector 13 at one end of the connecting arm 12 is engaged with the cooling fan center shell. This allows the cooling fan and the water storage cooling shell 9 to form a rotating structure that follows the rotation of the motor shaft. During the rotation, the water storage cooling shell 9 and the water deflector 10 arranged on its inner wall can deflect the cooling water, which can improve the fluidity of the cooling water and promote uniform flushing of the rear end shell 1 of the machine body for efficient heat conduction.
[0028] Further as Figure 1 As shown, it is worth noting that the side surface of the rear end shell 1 of the body is provided with mounting holes 3, and the rear end of the rear end shell 1 of the body is provided with heat dissipation holes 4.
[0029] In summary: Water is injected into the water storage tank 11 of the water storage cooling shell 9 through the water injection pipe 14, thus creating a water storage layer between the rear shell 1 of the machine body and the water storage cooling shell 9 to achieve water cooling. When the oil pump motor is working, it can combine the cooling fan and the water storage cooling shell 9 to form a rotating structure that rotates with the motor shaft. During the rotation, the water storage cooling shell 9 and the water deflector 10 arranged on its inner wall can deflect the cooling water, which can improve the fluidity of the cooling water and promote uniform flushing of the rear shell 1 of the machine body for efficient heat conduction.
