Description

Technical Field

[0001] This invention relates to the field of refrigeration equipment technology, and in particular to a three-gear refrigerant pump. Background Technology

[0002] With the increasing number of electronic devices, the heat generated during synchronous operation is substantial. To ensure cooling, external liquid cooling is generally used, leading to a growing number of refrigerant pumps of various types. The fully enclosed gear pump is a commonly used refrigerant pump in refrigeration systems. Existing gear pumps typically employ a structure with meshing main and auxiliary gears, a single-structure design. Within given space constraints, increasing the pump's flow rate often requires increasing the gear volume or tooth width, significantly increasing the overall pump size. Furthermore, refrigerant easily vaporizes under pressure changes, resulting in gas trapped within the liquid. This can cause cavitation during transportation, increasing noise and causing internal mechanical wear due to prolonged gas impact, affecting the long-term stable operation of the device. It also increases energy consumption. Conventional gear pump drive units are often externally mounted or use independent cooling, unable to achieve self-cooling using the refrigerant medium, further increasing energy consumption.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0016] 1. Through the cooperation of multiple devices, a large flow rate pump can be achieved in a limited space using a three-gear system. This adapts to cooling operations under different working conditions at different stages, and accommodates a wide range of operations. Adjustments can be made according to different states to achieve energy-saving transportation. Furthermore, the built-in motor allows for self-cooling of the internal drive mechanism using refrigerant, ensuring continuous and stable operation without the need for external cooling, thus reducing energy consumption. The integrated welding prevents refrigerant spillage and external influences on the internal components, ensuring device stability, reducing maintenance costs, and guaranteeing overall operational stability.

[0017] 2. By moving the pump body's own shaft, the pump can extract and compress the gas inside the pump body. This removes tiny bubbles generated by the refrigerant during temperature changes, reducing noise and vibration caused by the bursting of bubbles under external pressure during transport. This also reduces the generation of ineffective energy and fatigue wear caused by long-term gas impact, extending the service life of the entire device. It avoids increased machine power caused by wear, thus stabilizing at a low power consumption. Its working efficiency is adjusted according to the pump body's own flow rate, reducing electrical control and automatically adapting to the gas removal work under different pump power levels.

[0030] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0031] Example 1

[0032] Please combine Figure 1 - Figure 3 A three-gear refrigerant pump includes: a protective shell 01, with an inlet tank 02 and an outlet tank 05 sealed and welded to both sides of the protective shell 01, respectively. The outlet tank 05 also houses functional components for providing control and power supply. The inlet tank 02 and outlet tank 05 are connected to external pipelines, allowing the entire pump body to communicate with the outside. Refrigerant can move from the inlet tank 02 through the pump body and finally exit from the outlet tank 05, forming a cycle. An outer shell 21 is fitted inside the protective shell 01. An actuator is connected to the side of the outer shell 21 near the inlet tank 02. A drive pipe 34 is fixedly connected to the middle of the actuator, and the other end of the drive pipe 34 is connected to a power supply mechanism. A separation mechanism located inside the protective shell 01 is provided between the actuator and the power supply mechanism. The drive pipe 34 is connected to the actuator, the power supply mechanism, and the separation mechanism. The outer casing 21 provides a sealed space within the protective casing 01. Under electromagnetic action, the power supply mechanism can generate torque, thereby driving the drive tube 34 in the middle to rotate. The torque is transmitted through the drive tube 34, driving the corresponding actuator and separation mechanism to move. The actuator drives the stationary fluid to flow, achieving the pumping operation. The separation mechanism can absorb the gas in the refrigerant fluid under a certain negative pressure, then pressurize it to liquefy it and promote its dissolution with the liquid, reforming it into a liquid, which is then discharged into the pump body to participate in subsequent flow. This reduces the residual gas in the subsequent refrigerant fluid, reduces the possibility of cavitation, and increases the stability of the entire system. The inlet tank 02 and the outlet tank 05 are respectively connected to the inlet pipe 03 and the outlet pipe 04 for the input and output of refrigerant, forming a reflux in conjunction with the overall device.

[0033] The actuator includes a limiting box 37 fixedly connected to the outer casing 21. A drive gear 36 fixedly connected to a drive pipe 34 is disposed in the middle of the limiting box 37. Encapsulation plates 20 are fixedly connected to both sides of the limiting box 37. Symmetrically arranged driven wheels 52 are rotatably connected between the two encapsulation plates 20. The driven wheels 52 mesh with the corresponding drive gears 36. Rotation of the drive pipe 34 drives the drive gears 36 to rotate, and the driven wheels 52 rotate synchronously in coordination with the rotation of the drive gears 36. During the meshing of the two gears, the volume change between the teeth drives the fluid to move from one side to the other. The shape of the limiting box 37 corresponds to the space formed by the piston 35 and the driven wheels 52. Similarly, to ensure the flow direction of the fluid during the flow process, a water passage hole is opened on the rotating encapsulation plate 20, and an adjustment component is connected inside the limiting box 37. The water passage hole ensures that the refrigerant temporarily stored in the liquid inlet box 02 can quickly enter the limiting box 37 and provide power to the rotating drive gear 36 and driven wheel 52 to drive them to flow. The flow rate of the refrigerant in the entire system can be adjusted according to the speed of the drive tube 34. The two symmetrical driven wheels 52 can generate more pumping space in a limited space, thereby generating a larger flow rate in the same volume. Furthermore, the adjustment component can perform secondary flow rate adjustment according to the required amount of refrigerant.

[0034] The implementation principle of this application embodiment is as follows: When pumping, an external power supply is connected, allowing the refrigerant to enter the inlet tank 02. At this time, the power supply mechanism works, driving the drive tube 34 to rotate, which in turn drives the corresponding driven wheel 52 and the driving gear 36 to rotate. During the meshing of the two gears, due to the volume change between the teeth, the fluid will be driven to move from one side to the other. The regulating component in the limiting tank 37 can adjust the flow rate. In conjunction with the change in the rotation speed of the power supply mechanism, different flow rate adjustments can be achieved. Furthermore, the separation mechanism can absorb the gas in the refrigerant fluid under a certain negative pressure, and then pressurize and liquefy it to re-form a liquid, which will then participate in the subsequent flow. This reduces the residual gas in the subsequent refrigerant fluid, reduces the possibility of cavitation, and increases the stability of the entire system.

[0035] Example 2

[0036] Combination Figure 1 - Figure 3 and Figure 7 - Figure 10 This embodiment is an improvement on embodiment 1, further described in the following aspects:

[0037] The adjustment assembly includes a movable frame 13 and a movable tube 22 that are slidably sleeved with the encapsulation plate 20. The movable frame 13 is located above the movable tube 22 and is situated on the upper side of the actuator, i.e., the water inlet end. The movable tube 22 is located on the lower side of the actuator, i.e., the water outlet end. The movable tube 22 is a tubular structure that connects both sides of the encapsulation plate 20 for refrigerant discharge. Multiple driving gears 36 and driven wheels 52 are arranged along the axis of the drive tube 34. A separator ring 51 fixedly connected to the limiting box 37 is provided between two adjacent driving gears 36. During operation, one or more sets of driving gears 36 and driven wheels 52 can be selected to operate in conjunction with the actuator. The refrigerant forms different contact areas, thereby achieving different unit flow rates and adjusting the flow rate of the entire system. The separator ring 51 separates the multiple sets of drive gears 36 to ensure the isolation between the drive gears 36 of different sets, ensuring the subsequent adjustment of different logarithmic gears, i.e., the flow rate. One end of the movable frame 23 and the movable tube 22 are respectively fixedly connected to the movable plate 15 and the movable plate 20, which are slidably sleeved with the limiting box 37. A bearing is slidably sleeved on the outer surface of the drive tube 34, and a movable ring 24 is sleeved on the outer surface of the bearing. The movable ring 24 is fixedly connected to the movable tube 22 and the movable frame 23. The movement of the movable ring 24 can drive the corresponding movable plate 30. The movement of the second frame 13 and the moving tube 22 synchronously drives the movement of the first moving plate 15 and the second moving plate 50. After the movement of the first moving plate 15 and the second moving plate 50, the refrigerant will come into contact with another set of driving gears 36 and driven wheels 52, achieving different contact areas between the liquid and the gears. This increases the flow rate per unit time, ensuring the system can meet the demand for large flow rates for extended periods or instantaneously. One side of the moving ring 24 is fixedly connected to a pulling frame 23 located inside the drive tube 34, and the other end of the pulling frame 23 is fixedly connected to a permanent magnet 19. A stabilizing cylinder 17, which is fixedly connected to the encapsulation plate 20, is slidably sleeved on the outside of the permanent magnet 19. An electromagnet 18 is fixedly connected inside the 7, and a spring 16 that rotates relative to the encapsulation plate 20 is fixedly connected to one side of the permanent magnet 19. When the electromagnet 18 is energized, it generates magnetism and pushes the permanent magnet 19 to move. When the current of the electromagnet 18 increases, it will drive the permanent magnet 19 to overcome the elastic force of the spring 16 and move a longer distance. At this time, the permanent magnet 19 drives the pulling frame 23 to move, which in turn drives the movement of the moving plate 15 and the moving plate 20, thereby realizing the flow regulation. The permanent magnet 19 rotates relative to the stabilizing cylinder 17. One end of the spring 16 is connected to a rotating ring, which is rotatably connected to the outer shell 21.

[0038] The drive tube 34 is provided with a through hole for the pull frame 23 to pass through. A baffle plate is fixedly connected in the middle of the drive tube 34. The baffle plate seals the other end of the drive tube 34 to reduce the turbulence of the refrigerant. The through hole is used for the passage and guidance of one side of the pull frame 23 to ensure the stability of the movement trajectory of the pull frame 23. The limiting box 37 is provided with multiple liquid extraction holes 53 for liquid passage. The top of the encapsulation plate 20 near the liquid inlet box 02 is provided with a water inlet hole that communicates with the liquid inlet box 02. The liquid extraction holes 53 allow the refrigerant to pass through. With the rotation of the gear, the refrigerant is pumped out. The water inlet hole ensures the communication between the inside of the limiting box 37 and the liquid inlet box 02.

[0039] The implementation principle of this application embodiment is as follows: During operation, the drive tube 34 drives the drive gear 36 to rotate, and with the cooperation of the driven wheel 52, pumping occurs. At this time, the electromagnet 18 generates magnetism when energized, which pushes the permanent magnet 19 to move. When the current of the electromagnet 18 increases, it drives the permanent magnet 19 to overcome the elastic force of the spring 16 and achieve a longer distance movement. At this time, the permanent magnet 19 drives the pull frame 23 to move, thereby driving the corresponding moving frame 13 and moving tube 22 to move through the movement of the moving ring 24, and synchronously driving the moving plate 15 and moving plate 50 to move. After the moving plate 15 and moving plate 50 move, the refrigerant will come into contact with another set of drive gears 36 and driven wheels 52. By selecting one or more sets, different liquid contact areas can be achieved, increasing the flow rate per unit time, ensuring the flow rate demand of the entire system for a long time or moment, thereby achieving different unit flow rate supply and adjusting the flow rate of the entire system.

[0040] Example 3:

[0041] Combination Figure 1 - Figure 6 Based on Embodiment 1, this embodiment is further improved in that: the power supply mechanism includes a rotor 29 which is fixedly sleeved with the drive tube 34, a stator 33 which is fixedly connected to the protective shell 01 is provided on the outside of the rotor 29, a plurality of flow holes are provided on the stator 33, and a packaging box 30 is provided on one side of the stator 33, and one side of the packaging box 30 is in contact with the functional component.

[0042] Both sides of the stator 33 are connected to the second encapsulation plate 28, and the second encapsulation plate 28 is provided with mating holes that communicate with the flow holes.

[0043] The functional components include a filter box 31 that snaps into the housing 21. Cleaning pipes 32 are connected to both the upper and lower sides of the filter box 31. One end of the cleaning pipe 32 extends to the outside of the liquid outlet tank 05. A sealing plug 06 that is threadedly connected to the liquid outlet tank 05 is fitted onto one end of the cleaning pipe 32. A flow divider ring 08 is connected to one side of the liquid outlet tank 05.

[0044] The implementation principle of this application embodiment is as follows: During operation, after being energized, the rotor 29 generates a periodically changing magnetic field. At this time, under the action of the stator 33, the rotor 29 rotates, which in turn drives the drive tube 34 to rotate. The encapsulation plate 28 can be selected as double-sided or single-sided according to the needs of the application scenario. The coolant can flow through the mating hole and carry away the heat generated by the rotor 29 during operation through heat exchange. Alternatively, it can directly contact the rotor 29 for direct heat exchange and rapid cooling. The refrigerant flows to the other side of the pump body through the mating hole to realize the flow of refrigerant.

[0045] Example 4: Combination Figure 1-3 This embodiment is an improvement on embodiment 1, further described in the following aspects:

[0046] The separation mechanism includes a guide tube 26 fixedly sleeved to the drive tube 34. The guide tube 26 has multiple M-shaped grooves connected end-to-end. A movable frame 11 is slidably sleeved within each M-shaped groove. During the rotation of the drive tube 34, the M-shaped grooves are driven to rotate. Under the interaction of forces, the M-shaped grooves drive the movable frame 11 to move periodically. This movement is parallel to the central axis of the drive tube 34. A piston 35 is connected to the other end of the movable frame 11. An air extraction cylinder 12 is slidably sleeved on the outside of the piston 35. The back-and-forth movement of the movable frame 11 drives the movable frame 11 to rotate. As the piston 35 moves back and forth, it periodically changes the size of the space inside the suction cylinder 12. A fixed cover plate 38, which is fixedly connected to the outer shell 21, is fixedly connected to the outside of the suction cylinder 12. The fixed cover plate 38 is rotatably sleeved with the drive pipe 34. A swing plate 27 is rotatably connected to the bottom of the fixed cover plate 38 via a spring hinge. Multiple triangular cones are set on the swing plate 27. A reverse pipe 25, extending from one side of the suction cylinder 12 to the other side of the fixed cover plate 38, is connected to one side. The fixed cover plate 38, in conjunction with the swing plate 27, can divide the pump body into two spaces, from the moving pipe... The coolant pumped out by pump 22 impacts the oscillating vane 27, causing it to expand at a certain angle. The triangular cone on the vane breaks up air bubbles inside the liquid, allowing gas to flow along the oscillating vane 27 into one side of the fixed cover plate 38 and remain on the top of the outer casing 21. The oscillating vane 27 rotates, opening and closing at different sizes to adapt to changes in flow rate. As the reverse pipe 25 moves within the suction cylinder 12, it alters the space within the suction cylinder 12. When the space inside the suction cylinder 12 expands, a negative pressure is generated, drawing gas from the refrigerant into the suction cylinder. Inside the cylinder 12, after the external pressure decreases, the gas in the fluid at the bottom of the outer shell 21 will also move upward, forming a virtuous cycle. The gas entering the suction cylinder 12 is compressed by the piston 35 and forms liquid again, entering the reverse tube 25 and finally being ejected back into the entire circulation system. The suction cylinder 12 and the piston 35 are fitted with a clearance and are equipped with a sealing ring. Under the action of the liquid's own tension and the sealing ring, a stable seal can be achieved inside the suction cylinder 12. At the same time, with the guidance of the one-way valve body, the gas flow direction is unidirectional.

[0047] The cross-section of the M-shaped groove adopts a T-shaped structure. The movable frame 11 is located on the outside of one end of the M-shaped groove and is rotatably connected to a roller that contacts the groove wall. One-way valves are connected to the vacuum pump 12 and the reverse pipe 25. A pressure limiting valve is also connected to the reverse pipe 25. Through the T-shaped structure, one end of the movable frame 11 can be limited to be located in the M-shaped groove. At the same time, the roller is used to reduce internal friction. The one-way valve limits the unidirectional flow of fluid. The pressure limiting valve opens only after the predetermined pressure is reached to ensure the pressure required for the gas to become liquid.

[0048] The implementation principle of this application embodiment is as follows: During the pumping operation, the guide tube 26 rotates under the torque force of the drive tube 34. At this time, under the constraint of the M-shaped groove, the moving frame 11 is driven to move back and forth periodically, which further drives the piston 35 to rotate periodically, thereby periodically changing the space inside the suction cylinder 12. When the space inside the suction cylinder 12 increases, the gas overflowing from the outer shell 21 is sucked through the suction cylinder 12. When the space inside the suction cylinder 12 decreases, the internal pressure increases, causing the gas to release heat and liquefy, while simultaneously promoting the compression of the gas. The gas dissolves back into the liquid and accumulates in the reverse tube 25. Finally, as the pressure continues to increase, the liquid is sprayed back into the outer casing 21 through the reverse tube 25, thereby reducing the amount of gas residue in the pump body and reducing the occurrence of cavitation or unstable flow. Depending on the actual working environment, a heat transfer sleeve can be fitted on the outside of the suction cylinder 12. At the same time, a heat insulation sleeve is fitted on the outside of the heat transfer sleeve to reduce the transfer of internal temperature of the pump body to it. The heat transfer sleeve conducts the heat on the suction cylinder 12 to the outside of the pump body for dissipation, thereby ensuring the energy transfer after the gas is compressed and released.

[0049] Example 5:

[0050] Combination Figure 4 - Figure 6This embodiment, based on Embodiment 1, further improves upon the following: the separation mechanism includes a functional box 07 integrally formed with the protective shell 01. Multiple springs 45 are fixedly connected inside the functional box 07, and the other end of each spring 45 is fixedly connected to a compression plate 42 that is slidably sleeved with the functional box 07. The compression plate 42 can move up and down within the functional box 07. During the movement of the compression plate 42, the size of the functional box 07 is changed, thereby changing the internal pressure and causing the gas to be pressurized into a liquid. The functional box 07 is located at the top of the pump body, i.e., at the upper position of the pump body. After the gas overflows, it will rise upwards. A fixed cover plate 38, which is fixedly connected to the outer casing 21, is located at the lower center of the compression plate 42. The fixed cover plate 38 is rotatably sleeved with the drive pipe 34. A swing plate 27 is rotatably connected to the bottom of the fixed cover plate 38 via a spring hinge. Multiple triangular cones are provided on the swing plate 27. The fixed cover plate 38 blocks the flow of fluid above. The swing plate 27 can rotate to different opening and closing sizes to adapt to the flow rate. The triangular cones can break up any air bubbles that may be present inside the liquid, allowing them to dissolve into the liquid or rise to the top of the pump body. The fixed cover plate 38 has connecting plates on both sides. The liquid accumulation block 44 and the movable frame 3 41 are fixedly connected. Multiple dripping pipes 46 are fixedly connected to the bottom of the liquid accumulation block 44. A suction pipe 43 connected to the compression plate 42 is provided on one side of the movable frame 3 41. A cam 40 is also fixedly sleeved on the drive pipe 34. The bottom of the movable frame 3 41 contacts the cam 40. The cam 40 rotates periodically along with the rotation of the drive pipe 34. At this time, the cam 40 pushes the movable frame 3 41 upward, squeezing the compression plate 42. Then, under the action of the spring 2 45, the compression plate 42 returns to its initial position, forming a periodic cycle. During this process… The suction pipe 43 draws air from inside the pump body into the functional box 07. The compression plate 42 compresses the internal space of the functional box 07, causing the gas to be pressurized into liquid and accumulate in the liquid accumulation block 44. When the pressure increases to a certain level, the liquid will be ejected through the drip pipe 46, forming a periodic gas-liquid circulation. One end of the suction pipe 43 is located above the pump body and is bent upwards to reduce the possibility of extracting liquid. At the same time, the functional box 07 is in contact with the outside, so that the heat generated during compression is dissipated to the outside through its own conduction, ensuring that the gas can be quickly and stably liquefied and achieve circulation.

[0051] Both the drip pipe 46 and the suction pipe 43 are connected to one-way valves. The drip pipe 46 is connected to a pressure limiting valve. A flexible sheet that is fixedly connected to the compression plate 42 is fixedly connected to one side of the fixed cover plate 38. Rollers are installed at the bottom of the movable frame 3 41. The one-way valve can ensure the direction of gas flow. The flexible sheet can block the gas flow trajectory and reduce the direct entry of gas into the other side of the pump body. At the same time, the rollers can reduce the friction between the cam 40 and the movable frame 3 41 and extend the service life.

[0052] The implementation principle of this application embodiment is as follows: During operation, driven by the torque force of the drive tube 34, the cam 40 rotates periodically, periodically lifting the moving frame 3 41, causing the moving frame 3 41 to move upward. With the cooperation of the spring 2 45, the compression plate 42 moves periodically within the function box 07, changing the space within the function box 07. When the space within the function box 07 increases, the gas overflowing from the outer shell 21 is drawn through the suction pipe 43. When the space within the function box 07 decreases, the internal pressure increases, causing the gas to release heat and liquefy, accumulating in the liquid accumulation block 44. Finally, under the action of pressure, it is sprayed back into the outer shell 21 through the drip pipe 46, thereby reducing the gas residue in the pump body and reducing the occurrence of cavitation or unstable flow.

[0053] The above embodiments are merely preferred embodiments of the present invention and should not be construed as limiting the scope of protection of the present invention. Any non-substantial changes and substitutions made by those skilled in the art based on the present invention shall fall within the scope of protection claimed by the present invention.
