Description

Technical Field

[0001] This application relates to the technical field of computer hardware and heat dissipation, and in particular to a pump body structure for a water-cooled chassis. Background Technology

[0002] With the rapid development of computer hardware, the performance of core components such as CPUs and GPUs is constantly improving, and power consumption and heat generation are also increasing significantly. Usually, heat dissipation devices are needed to reduce the temperature, thereby improving their data processing speed.

[0003] Water cooling removes heat generated by hardware from the heat source through the circulation of liquid, and then dissipates the heat into the air through a radiator, achieving efficient heat dissipation with low noise. In a water cooling system, the pump is the core power component. Its main function is to drive the coolant to circulate continuously in a closed loop, ensuring that heat is carried away in a timely manner. The performance of the pump directly affects the heat dissipation efficiency, stability, and lifespan of the entire water cooling system, and its structural design is one of the key aspects of water cooling technology development.

[0004] Regarding the aforementioned technologies, the applicant believes that they suffer from defects such as unstable liquid supply and imperfect waterproofing. Utility Model Content

[0005] To address the aforementioned technical problems, this application provides a pump body structure for a water-cooled chassis.

[0006] The pump body structure of the water-cooled chassis provided in this application adopts the following technical solution:

[0007] A pump body structure for a water-cooled chassis includes an outer shell. An internal partition divides the outer shell into an upper chamber and a lower chamber. A water pump device is mounted on the partition of the upper chamber. The water pump device includes a pump body assembly and a volute. The volute is fixedly connected to the partition. The lower chamber contains a drive groove sealed and connected to the middle of the volute, and a bottom drive device fixedly connected to the partition. An inlet and an outlet are located on one side of the outer shell. The inlet communicates with the outer shell, and the outlet communicates with the volute. A water tank is located at the top of the outer shell and is fixedly connected to the outer shell. An inlet hole is provided between the water tank and the volute.

[0008] By adopting the above technical solution, the outer shell is divided into upper and lower chambers by a partition, avoiding direct contact between the drive unit and the water flow, eliminating the risk of leakage and short circuit, and further preventing water seepage from affecting circuit safety. The water inlet is connected to the shell, and the water outlet is connected to the volute. The water flow path from the water inlet, upper chamber, water tank, water inlet hole, water pump device, and water outlet is short and without redundant turns, reducing water flow loss. The drive slot is sealed in the lower chamber and connected to the middle of the volute. One end of the drive unit is installed on the outer wall of the drive slot, and the power of the drive unit can directly act on the water pump device, reducing power transmission loss and further enhancing water circulation efficiency. The outer shell integrates the water tank, drive unit, and water pump device into one unit. The integrated water tank ensures stable water supply to the water pump device and facilitates observation of the coolant status. The bottom cover is removable for easy cleaning of internal scale or replacement of worn parts.

[0009] Preferably, the pump body assembly includes a ceramic shaft, an impeller, and an inner magnetic shaft. One end of the ceramic shaft is fixedly connected to the drive groove, the impeller is fixedly connected to one end of the inner magnetic shaft, the inner magnetic shaft is mounted on the ceramic shaft, and the inner magnetic shaft is rotatably connected to the ceramic shaft and the inner wall of the drive groove.

[0010] By adopting the above technical solutions, the ceramic material has a hardness much higher than that of metal or plastic, and its surface is smooth. The frictional resistance during the rotational engagement with the inner magnetic shaft is small, which can reduce energy loss during operation and improve the efficiency of the water pump. The ceramic shaft is not easily corroded by coolant and will not rust or age due to long-term contact with liquid, thus extending the service life of the shaft and reducing the risk of water leakage caused by shaft damage. The inner magnetic shaft is usually engaged with the magnetic component of the drive device in the lower chamber to transmit power through magnetic coupling, eliminating the need for traditional mechanical shaft seals and eliminating the risk of water leakage at the shaft seal.

[0011] Preferably, the lower chamber is further provided with multiple sets of mounting and positioning posts and light guide posts. The mounting and positioning posts are fixedly connected to the partition. A light-transmitting cover is provided on the partition on one side of the volute. The light-transmitting cover is fixedly connected to the partition. The light guide post passes through the partition and is installed inside the light-transmitting cover. The light guide post is fixedly connected to the partition.

[0012] By adopting the above technical solution, multiple sets of installation positioning columns are fixedly connected to the bottom of the partition. The drive device can be rigidly positioned through preset holes or snap-fit ​​structures to ensure accurate installation of the drive components. The light guide column penetrates the partition and is set at the light-transmitting cover, which can efficiently export the light source in the lower chamber and judge the water pump status by the change of light color.

[0013] Preferably, the drive device includes a control circuit board, a stator core, a wire frame, and a stator winding. The stator winding is mounted on the wire frame, the wire frame is fixedly connected to one end of the stator core, the other end of the stator core is fixedly connected to the outer wall of the drive slot, the stator core is fixedly connected to a partition plate, and the control circuit board is fixedly connected to the stator winding.

[0014] By adopting the above technical solution, the stator winding is installed on the wire frame, which can fix the shape and position of the winding. The wire frame is fixedly connected to one end of the stator core. The stator core, as a magnetic conductive component, can enhance the magnetic field strength generated by the winding and improve the electromagnetic force conversion efficiency. The rigid connection between the two ensures the stable magnetic field distribution and avoids magnetic field deviation caused by loose components. The other end of the stator core is fixedly connected to the drive slot. The magnetic field of the stator core acts efficiently on the inner magnetic shaft in the drive slot. The control circuit board is fixedly connected to the stator winding and can directly adjust the current magnitude, frequency, or phase of the winding to achieve precise control of the stator magnetic field strength and direction, thereby adjusting the rotational speed of the inner magnetic shaft.

[0015] Preferably, a small light bulb is provided on one side of the control circuit board, and the position of the small light bulb corresponds to that of the light guide column.

[0016] By adopting the above technical solution, the light generated by the light bulb is directionally transmitted to the light-transmitting cover through the light guide column, so that the operating status of the pump can be intuitively perceived through the light status.

[0017] Preferably, a filter outlet plate is provided between the outer shell and the water tank, and the filter outlet plate is detachably connected to the outer shell.

[0018] Preferably, the upper chamber is provided with filter holes at the connection between the upper chamber and the filter outlet plate, and the filter holes connect the upper chamber to the water tank.

[0019] By adopting the above technical solution, the filter hole connects the water tank and the upper chamber. When the water pump is working, the coolant in the water tank is replenished in time when the water level fluctuates due to pressure changes in the upper chamber, so as to maintain the total balance of coolant in the system and avoid the situation of flow interruption or water overflow.

[0020] Preferably, the water inlet is located on the filter outlet plate, the water tank is connected to the volute through the water inlet on the filter outlet plate, and a sealing gasket is provided at the connection between the filter outlet plate and the volute, and the sealing gasket is fixedly connected to the filter outlet plate.

[0021] By adopting the above technical solution, the water inlet hole serves as a connecting channel between the water tank and the volute, directing the coolant in the water tank into the volute. Combined with the filter hole design, a water flow path is formed, consisting of external water inlet, upper chamber, filter hole, water tank, water inlet hole, and volute, ensuring a stable coolant supply to the water pump. The water tank also serves as a buffer and storage for the liquid within the system, preventing instantaneous flow fluctuations from affecting the heat dissipation effect.

[0022] Preferably, the top of the water tank is provided with a protruding liquid inlet and a sealing cap. The protruding liquid inlet is fixedly connected to the top of the water tank, and the sealing cap is detachably connected to the protruding liquid inlet.

[0023] By adopting the above technical solution, the convex filling port protrudes outward, and the connection between its edge and the top of the water tank is an outward transition. When subjected to external force, the stress will be evenly distributed along the convex arc surface, avoiding stress concentration at the connection root. The convex design can also be used for filling with various auxiliary tools, making the operation more flexible for scenarios that require precise control of the filling amount or the addition of a small amount of coolant, and preventing liquid overflow from contaminating the inside of the chassis.

[0024] Preferably, the lower chamber is provided with an installation groove, the installation groove is provided with a bottom cover, the bottom cover is detachably connected to the installation groove, a wire hole is provided on one side of the installation groove, and a shock-absorbing base is provided on the bottom cover, the shock-absorbing base is detachably connected to the bottom cover.

[0025] By adopting the above technical solution, the bottom cover and the mounting groove are detachably connected. A wire hole is provided on one side of the mounting groove to further prevent water seepage from affecting circuit safety. The shock-absorbing base is usually made of elastic material. When the water pump is running, it will generate vibration. The base can absorb some of the vibration energy through its own deformation, avoiding the vibration from being directly transmitted to the chassis or desktop through the bottom cover, thereby reducing resonance noise and improving the quietness of equipment operation.

[0026] In summary, this application includes at least one of the following beneficial technical effects:

[0027] The stator winding is mounted on a wire frame, which fixes the shape and position of the winding. The wire frame is fixedly connected to one end of the stator core. The stator core, as a magnetic conductor, enhances the magnetic field strength generated by the winding and improves the electromagnetic force conversion efficiency. The rigid connection between the two ensures a stable magnetic field distribution and avoids magnetic field deviation caused by loose components. The other end of the stator core is fixedly connected to the drive slot. The magnetic field of the stator core acts efficiently on the inner magnetic shaft in the drive slot. The control circuit board is fixedly connected to the stator winding and can directly adjust the current magnitude, frequency, or phase of the winding to achieve precise control of the stator magnetic field strength and direction, thereby adjusting the rotational speed of the inner magnetic shaft.

[0028] The water inlet serves as a connecting channel between the water tank and the volute, directing the coolant from the water tank into the volute. Combined with the filter hole design, it forms a water flow path from the external water inlet, upper chamber, filter hole, water tank, water inlet, to the volute, ensuring a stable coolant supply to the water pump. The water tank buffers and stores the liquid within the system, preventing instantaneous flow fluctuations from affecting the heat dissipation effect. Attached Figure Description

The other end of the stator core 22 is fixedly connected to the outer wall of the drive slot 131 inside the lower chamber 13. The stator core 22 and the stator... The magnetic field of the winding 24 acts efficiently on the inner magnetic shaft 1413 in the drive slot 131, causing the inner magnetic shaft 1413 to rotate and drive the impeller 1412 to rotate.

[0035] A water tank 3 is mounted on the top of the outer shell 1, and the water tank 3 is fixedly connected to the outer shell 1. Various fixing methods can be used between the water tank 3 and the outer shell 1. A filter outlet plate 4 is installed between the outer shell 1 and the water tank 3. A filter hole 41 is provided on the connection part between the filter outlet plate 4 and the upper chamber 12, connecting the upper chamber 12 and the water tank 3. A water inlet hole 42 is provided on the connection part between the filter outlet plate 4 and the volute 142, and the water tank 3 is connected to the volute 142 through a water inlet 15. A sealing gasket 43 is provided at the connection point between the filter outlet plate 4 and the volute 142 to prevent liquid from directly flowing into the volute 142, and the sealing gasket 43 is fixedly connected to the filter outlet plate 4. A water inlet 15 and a water outlet 16 are provided on one side of the outer shell 1. The water inlet 15 communicates with the upper chamber, and the water outlet 16 communicates with the volute 142. 42 is connected, and the liquid flows into the upper chamber through the inlet 15.

The sealing cover 32 is detachably connected to the protruding liquid inlet 31. The protruding liquid inlet 31 reduces the risk of cracking compared to the concave type.

The shock-absorbing base 7 reduces the vibration transmitted to other hardware.

[0036] The working principle of the pump body structure of the water-cooled chassis in this application is as follows: After the control circuit board 21 is powered on, the current passes through the stator winding 24 to generate an alternating magnetic field. Since there is a magnetic coupling relationship between the stator core 22 and the inner magnetic shaft 1413 in the drive slot 131, the magnetic field of the stator winding 24 and the stator core 22 will efficiently act on the inner magnetic shaft 1413, forming a magnetic drive torque, which drives the inner magnetic shaft 1413 to rotate around the ceramic shaft 1411 and the drive slot 131. One end of the inner magnetic shaft 1413 is fixedly connected to the impeller 1412. Therefore, the rotation of the inner magnetic shaft 1413 directly drives the impeller 1412 to rotate synchronously, providing power for liquid transportation. The external liquid flows into the upper chamber 12 of the outer shell 1 through the inlet 15. The liquid in the upper chamber 12 enters the water tank 3 through the filter holes 41 on the filter outlet plate 4. The convex top of the water tank 3 The liquid inlet 31 can quickly replenish the liquid when it is insufficient. The sealing cover 32 ensures the airtightness of the water tank 3. The liquid in the water tank 3 flows into the volute 142 through the water inlet 42 on the filter outlet plate 4. There is a sealing gasket 43 at the connection between the water inlet 42 and the volute to prevent the liquid from leaking directly into the volute 142 without the water inlet 42. The rotating impeller 1412 generates centrifugal force or pressure difference in the volute 142, which discharges the liquid that has entered the volute 142 from the outlet 16, thus completing the liquid delivery. The vibration generated by the pump body during operation is absorbed by the shock-absorbing base 7 at the bottom, reducing the transmission to external hardware. The small light bulb 211 on the control circuit board 21 transmits light to the light-transmitting cover 113 on the partition 11 through the light guide column 112. The user can observe the status of the small light bulb 211 through the light-transmitting cover 113 and intuitively judge whether the water pump is operating normally.
