Description

Technical Field

[0001] The invention relates to a liquid pump structural profile and a cooling system for supercharging. Background Art

[0002] With the demand for improved charging efficiency of electric vehicles, liquid-cooled super charging piles have become a hot topic in the industry. Tesla's fast charging piles are the earliest representative. The number and increment of liquid-cooled charging piles are constantly increasing. For liquid-cooled gun lines, each gun line on the charging pile usually needs to be equipped with a liquid cooling device. The basic structure of the liquid cooling device is shown in the attached manual. Figure 1 As shown, the system includes a series of devices such as liquid level sensors, pumps, overflow valves, pressure sensors, temperature sensors, radiator assemblies, and PLCs. Considering that the liquid cooling device serves the gun line, there are relatively stringent reliability and safety requirements. Therefore, each product needs to undergo rigorous testing. The test content not only includes the performance of the above-mentioned devices, but also includes PLC logic verification, heat dissipation capability verification, etc.

[0003] The supercharging system generates a lot of heat when processing high-load tasks, so heat dissipation is an important issue in the design and operation and maintenance of the supercharging system.

[0004] In the prior art, a cooling system composed of rotating machinery or fluid machinery is generally used for cooling the supercharging system. During the operation of the rotating machinery or fluid machinery, since the two rotors need to contact each other, friction and wear will generate heat after contact. At the same time, excessive rotation amplitude between the rotors will cause a greater impact, aggravate the degree of wear, and reduce the service life. Summary of the Invention

[0005] The purpose of the present invention is to address the deficiencies in the prior art and provide a technical solution for a liquid pump structural profile and a cooling system for supercharging, which can not only improve the stability and reliability of the engagement between the inner rotor and the outer rotor, but also reduce the friction and wear during the rotation of the inner rotor and the outer rotor, while avoiding the impact caused by excessive rotation of the inner rotor, thereby improving the fluid delivery efficiency.

[0006] In order to solve the above technical problems, the present invention adopts the following technical solutions: A liquid pump structural profile for supercharging, comprising An inner rotor and an outer rotor are eccentrically arranged, and the inner rotor and the outer rotor cooperate to form a cavity; Its characteristics are: The inner rotor comprises a disc-shaped rotor body, on which at least one worm groove and at least one guide groove are provided; The outer rotor includes an annular rotor outer ring, at least one worm claw portion and at least one limiting groove provided on the inner side of the rotor outer ring; It also includes a swinging member connected to the limiting groove and the guide groove; When eccentric motion occurs between the inner rotor and the outer rotor, the worm claw part performs eccentric reciprocating motion along the worm claw groove, one end of the swinging member rotates along the limit groove, and the other end moves telescopically along the guide groove, thereby realizing the flow of fluid in the cavity with continuously changing volume and the worm claw groove.

[0007] Through the design of the above structure, not only the stability and reliability of the engagement between the inner rotor and the outer rotor can be improved, but also the friction and wear during the rotation of the inner rotor and the outer rotor can be reduced. At the same time, the impact caused by the excessive rotation of the inner rotor can be avoided, thereby improving the fluid transportation efficiency.

[0008] Furthermore, the worm claw portion and the worm claw groove are arranged in the same direction, and the size of the worm claw portion is smaller than that of the worm claw groove, which is beneficial for the fluid to flow along the cavity and the worm claw groove during the engagement process of the worm claw portion and the worm claw groove, thereby improving the conveying efficiency.

[0009] Furthermore, the worm claw portion is formed by bending the inner wall of the rotor outer ring inward to form an integrated structure, which is easy to process and manufacture and reduces manufacturing costs.

[0010] Furthermore, the worm groove is communicated with the cavity for continuous fluid delivery.

[0011] Furthermore, the swinging member includes a rotating body and a plate body. The rotating body is arranged at one end of the plate body. The rotating body is rotatably connected to the limiting groove. The plate body is limited in the guide groove and moves telescopically along the guide groove. Through the design of the rotating body and the plate body, the rotation amplitude of the inner rotor can be reduced, which is conducive to stable fluid transportation.

[0012] Furthermore, the length of the plate body is shorter than the length of the guide groove, thereby avoiding a large impact between the end of the plate body and the rotor body, extending the service life and reducing noise.

[0013] Furthermore, the rotor body is provided with a first outer meshing section, a first inner meshing section, a second inner meshing section, a first transition section and a second transition section. The first outer meshing section is connected to the first inner meshing section through the first transition section, the first inner meshing section is connected to the second transition section through the second inner meshing section, and the second transition section is connected to the other end of the first outer meshing section. The design of the above structure is conducive to the effective meshing of the inner rotor and the outer rotor during the eccentric motion, thereby improving the utilization rate of the fluid.

[0014] Furthermore, a second outer meshing section is provided inside the outer ring of the rotor, and the worm claw portion includes a third transition section, a fourth transition section, a third inner meshing section and a fourth inner meshing section. The second outer meshing section is connected to the third inner meshing section through the fourth transition section, and the third inner meshing section is connected to the third transition section through the fourth inner meshing section. The third transition section is connected to the other end of the second outer meshing section. The design of the above structure is conducive to the effective meshing of the inner rotor and the outer rotor during eccentric motion, thereby improving the utilization rate of the fluid.

[0015] Furthermore, the first transition section and the fourth transition section are both arc-shaped structures, and the second transition section and the third transition section are both pointed-angle structures or arc-shaped structures, which can meet the installation requirements of liquid pumps or air pumps with different structures.

[0016] Furthermore, the inner rotor drives the outer rotor to perform synchronous rotational motion in the same direction, or the outer rotor is fixed and the inner rotor creeps inside the outer rotor, thereby enabling the fluid to flow between the worm groove and the cavity, thereby expanding the scope of application.

[0017] A cooling system includes a radiator, a water tank, a liquid pump, a supercharging connector and several liquid cooling modules. The liquid cooling modules are connected in parallel. One end of the liquid cooling module is connected to the water tank through the radiator, and the other end of the liquid cooling module is connected to the water tank through the liquid pump. The supercharging connector is connected to the liquid cooling module, the radiator and the liquid pump. It is characterized in that the liquid pump adopts the liquid pump structural profile as described above; the cooling system can keep the charging gun and cable at a constant low temperature during supercharging, enhance their current carrying capacity, take away the heat generated during high-power charging, and reduce the risk caused by excessive heat release.

[0018] The present invention has the following beneficial effects due to the adoption of the above technical solution: 1. The present invention can not only improve the stability and reliability of the engagement between the inner rotor and the outer rotor of the liquid pump, but also reduce the friction and wear during the rotation of the inner rotor and the outer rotor, while avoiding the impact caused by the excessive rotation of the inner rotor, thereby improving the fluid delivery efficiency.

[0019] 2. Through the design of the rotating body and the plate body, the rotation amplitude of the inner rotor can be reduced, which is conducive to the stable transportation of the fluid.

[0020] 3. The inner rotor drives the outer rotor to rotate synchronously in the same direction, or the outer rotor is fixed and the inner rotor creeps inside the outer rotor, so that the fluid flows between the worm groove and the cavity, expanding the scope of application.

DETAILED DESCRIPTION

[0023] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0024] In order to enable those skilled in the art to better understand the solutions of the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts should fall within the scope of protection of the present invention.

[0025] It should be noted that the terms "first," "second," and so on in the description and claims of the present invention and the accompanying drawings are used to distinguish similar items and are not necessarily used to describe a specific order or precedence. Furthermore, the terms "including," "having," and any variations thereof are intended to cover non-exclusive inclusions.

[0026] like Figures 1 to 5 As shown, the structural profile and cooling system of a liquid pump 8 for supercharging of the present invention are shown, which includes an eccentrically arranged inner rotor 1 and an outer rotor 2, wherein the inner rotor 1 and the outer rotor 2 cooperate to form a cavity 3.

[0027] The inner rotor 1 includes a disc-shaped rotor body 101, which is provided with at least one worm groove 102 and at least one guide groove 103. This application takes one worm groove 102 and one guide groove 103 as an example for description.

[0028] The outer rotor 2 includes an annular rotor outer ring 201, at least one worm claw portion 202 and at least one limiting groove 203 provided on the inner side of the rotor outer ring 201. This application takes one worm claw portion 202 and two limiting grooves 203 as an example for description.

[0029] The worm claw portion 202 and the worm claw groove 102 are arranged in the same direction, and the size of the worm claw portion 202 is smaller than that of the worm claw groove 102, which is beneficial for the fluid to flow along the cavity 3 and the worm claw groove 102 during the engagement process of the worm claw portion 202 and the worm claw groove 102, thereby improving the conveying efficiency.

[0030] The worm claw portion 202 is formed by bending the inner wall of the rotor outer ring 201 inwardly to form an integral structure, which is easy to process and manufacture and reduces manufacturing costs.

[0031] The worm groove 102 is communicated with the cavity 3 for continuous fluid delivery.

[0032] The rotor body 101 is provided with a first outer meshing section 104, a first inner meshing section 107, a second inner meshing section 108, a first transition section 106 and a second transition section 105. The first outer meshing section 104 is connected to the first inner meshing section 107 via the first transition section 106, the first inner meshing section 107 is connected to the second transition section 105 via the second inner meshing section 108, and the second transition section 105 is connected to the other end of the first outer meshing section 104. The above-mentioned structural design facilitates effective meshing of the inner rotor 1 and the outer rotor 2 during eccentric motion, thereby improving the utilization rate of the fluid.

[0033] A second outer meshing section 204 is provided within the rotor outer ring 201, and the worm portion 202 includes a third transition section 205, a fourth transition section 206, a third inner meshing section 207, and a fourth inner meshing section 208. The second outer meshing section 204 is connected to the third inner meshing section 207 via the fourth transition section 206, and the third inner meshing section 207 is connected to the third transition section 205 via the fourth inner meshing section 208. The third transition section 205 is connected to the other end of the second outer meshing section 204. The above-mentioned structural design facilitates effective meshing between the inner rotor 1 and the outer rotor 2 during eccentric motion, thereby improving fluid utilization.

[0034] The first transition section 106 and the fourth transition section 206 are both arc-shaped structures, and the second transition section 105 and the third transition section 205 are both pointed-angle structures or arc-shaped structures, which can meet the installation requirements of liquid pumps 8 or air pumps of different structures.

[0035] It also includes a swinging member 4, which is connected to the limiting groove 203 and the guide groove 103; the swinging member 4 includes a rotating body 401 and a plate body 402, the rotating body 401 is arranged at one end of the plate body 402, the rotating body 401 is rotatably connected to the limiting groove 203, the plate body 402 is limited in the guide groove 103, and moves telescopically along the guide groove 103. Through the design of the rotating body 401 and the plate body 402, the rotation amplitude of the inner rotor 1 can be reduced, which is conducive to stable fluid transportation.

[0036] The length of the plate body 402 is shorter than that of the guide groove 103 , which prevents the end of the plate body 402 from having a large impact with the rotor body 101 , thereby extending the service life and reducing noise.

[0037] When eccentric motion occurs between the inner rotor 1 and the outer rotor 2, the worm claw portion 202 performs eccentric reciprocating motion along the worm claw groove 102, one end of the swinging member 4 rotates along the limiting groove 203, and the other end telescopically moves along the guide groove 103, thereby realizing the flow of fluid in the cavity 3 with continuously changing volume and the worm claw groove 102.

[0038] The inner rotor 1 drives the outer rotor 2 to rotate synchronously in the same direction, or the outer rotor 2 is fixed and the inner rotor 1 creeps inside the outer rotor 2, so that the fluid flows between the worm groove 102 and the cavity 3, thereby expanding the scope of application.

[0039] The above-mentioned structural design not only improves the stability and reliability of the meshing between the inner rotor 1 and the outer rotor 2, but also reduces the friction and wear during the rotation of the inner rotor 1 and the outer rotor 2. At the same time, it avoids the impact caused by excessive rotation of the inner rotor 1, thereby improving the fluid conveying efficiency.

[0040] like Figure 6 As shown, a cooling system of the present invention includes a radiator 6, a water tank 7, a liquid pump 8, a supercharging connector 9 and several liquid cooling modules 5. The liquid cooling modules 5 are connected in parallel with each other. One end of the liquid cooling module 5 is connected to the water tank 7 through the radiator 6, and the other end of the liquid cooling module 5 is connected to the water tank 7 through the liquid pump 8. The supercharging connector 9 is connected to the liquid cooling module 5, the radiator 6 and the liquid pump 8. The liquid pump 8 adopts the liquid pump 8 structural line as described above; the cooling system can keep the charging gun and the cable at a constant low temperature during supercharging, enhance its current carrying capacity, take away the heat generated during high-power charging, and reduce the risk caused by excessive heat release.

[0041] The above are only specific embodiments of the present invention, but the technical features of the present invention are not limited thereto. Any simple changes, equivalent replacements, or modifications based on the present invention to achieve substantially the same technical effects are all within the scope of protection of the present invention.
