Description

Technical Field

[0001] This invention belongs to the field of chassis technology, specifically relating to a self-circulating liquid supply component and device inside a chassis. Background Technology

[0002] Liquid cooling, as a cooling method with excellent heat dissipation efficiency, is widely used in temperature control scenarios of various heat-generating equipment. With the high specific heat capacity of liquids, it can quickly remove the heat generated during equipment operation, meeting the heat dissipation needs of high-power, high-heat-generating equipment.

[0003] In existing conventional liquid cooling systems, such as the dual-cooling-mode liquid cooling unit (CN222192862U) disclosed in the prior art, the structural design typically includes multiple independent components such as a frame panel, power supply and control unit, circulating pump, fan, air-cooled heat exchange module, thermal expansion valve, and plate heat exchanger. Due to the large number of components, conventional liquid cooling systems are bulky. Limited by the internal installation space of the equipment chassis, some core components cannot be integrated inside the chassis and must be externally mounted. This not only increases the overall space occupied by the liquid cooling system but also increases the difficulty of installation and layout. Furthermore, the distributed structure of multiple components makes the overall structure of the liquid cooling system complex, the assembly and maintenance processes of each component and connecting pipeline are cumbersome, and subsequent maintenance operations are difficult and costly.

[0004] In summary, existing liquid cooling devices are difficult to integrate with equipment chassis, have poor maintenance convenience, and high operating costs, failing to meet the development needs of various equipment for miniaturized, integrated, and low-cost cooling devices. Summary of the Invention

[0005] To address the aforementioned technical problems, this invention provides a self-circulating liquid supply component and device within a chassis, thereby resolving the issues in the prior art. The technical solution adopted by this invention is as follows: A self-circulating cooling medium supply assembly for use within a chassis includes a water tank, a return assembly, and a water pump. The return assembly is positioned along a first direction on a first side of the water tank and is used to receive and return the returning cooling medium to the water tank. The water pump, positioned along a second direction perpendicular to the first direction, is used to output the cooling medium from the water tank.

[0006] Furthermore, the outlet of the water pump and the inlet of the return liquid assembly are located on the same side of the water tank.

[0007] Furthermore, the water tank outlet, water pump inlet, water pump outlet, and return liquid assembly inlet are all located on the same side of the water tank.

[0008] Furthermore, the inlet of the return liquid assembly is positioned facing the center of the water tank.

[0009] Furthermore, the water pump is equipped with a discharge assembly, which includes a discharge channel, a first channel, and a second channel. The discharge channel includes a first wall and a second wall disposed opposite to each other, the first wall including a first surface facing the outlet of the water pump. The first channel is disposed on the first surface for communicating with the outlet of the water pump, and the second channel is disposed on the first surface for discharging the medium.

[0010] Furthermore, the discharge channel also includes a side skirt wall, which is arranged circumferentially around the first wall, and a second wall is connected to the side skirt wall.

[0011] Furthermore, the discharge assembly also includes a docking part, which is provided with a through channel, a second channel passing through the through channel, and an extension ring provided at the end of the second channel away from the first surface. The docking part abuts against the side of the extension ring closer to the first surface.

[0012] Furthermore, a receiving recess is provided on the side of the expansion ring away from the first surface, the receiving recess being used to receive the seal.

[0013] Furthermore, the water tank is equipped with a self-relieving pressure device.

[0014] On the other hand, this application embodiment also provides a device, including a chassis, a liquid cooling component and a heat exchange component housed in the chassis, and also including the self-circulating liquid supply component in the chassis as described in the above embodiment. The outlet of the liquid return component is connected to the inlet of the heat exchange component, the outlet of the heat exchange component is connected to the inlet of the water tank, the outlet of the water pump is connected to the inlet of the liquid cooling component, and the outlet of the liquid cooling component is connected to the inlet of the liquid return component.

[0015] The present invention has the following beneficial effects: 1. By placing the return fluid assembly on the first side of the water tank along a first direction, and placing the water pump on one side of the water tank along a second direction, this device integrates both liquid storage and medium circulation functions. This device can operate normally even when completely installed inside the chassis, and the chassis can achieve internal coolant self-circulation without external power. Furthermore, integrating the water pump and return fluid assembly on different sides of the water tank makes the overall structure more compact, occupies less space, and is easier to install inside the chassis.

[0016] 2. By placing the water tank outlet, water pump inlet, water pump outlet, and return fluid assembly inlet on the same side of the water tank, the path of the cooling medium from the water tank outlet to the water pump outlet is shortened, reducing pump suction head loss, lowering pump energy consumption, and reducing operating costs. Furthermore, the shorter piping significantly saves installation space between the pump and the water tank, improving the integration of the device and making it easier to install within a chassis.

Detailed Implementation

[0019] The following will be based on embodiments of the present invention. Figures 1-8 The technical solutions in the embodiments of the present invention will be clearly and completely described. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Unless otherwise specified, the technical means used in the embodiments are conventional means well known to those skilled in the art.

[0020] On one hand, this application provides an in-chassis self-circulating liquid supply assembly for installation within a chassis 24, comprising a water tank 1, a return liquid assembly 2, and a water pump 3. The return liquid assembly 2 is disposed on a first side of the water tank 1 along a first direction, and is used to receive the returning cooling medium and transport it back to the water tank 1. The water pump 3 is used to output the cooling medium from the water tank 1, and is disposed on a second side of the water tank 1 along a second direction, with the first direction perpendicular to the second direction.

[0021] The chassis 24 can be the chassis 24 of a computer device.

[0022] Water tank 1 is used to hold the cooling medium.

[0023] After the cooling medium in water tank 1 is output, it circulates externally and eventually returns to water tank 1 through the return liquid assembly 2.

[0024] Water pump 3 enables the cooling medium in water tank 1 to be output from water tank 1.

[0025] The first direction can be the direction shown by the Z-axis in the figure, and the second direction can be the direction shown by the Y-axis in the figure. The first direction can be the length or width direction of water tank 1, and the second direction can be the thickness direction of water tank 1.

[0026] By placing the liquid return assembly 2 on the first side of the water tank 1 along the first direction and the water pump 3 on the second side of the water tank 1 along the second direction, this device integrates liquid storage and media circulation functions. The device can also operate normally entirely within the chassis 24. Furthermore, integrating the water pump 3 and the liquid return assembly 2 on different sides of the water tank 1 makes the overall structure of the device more compact, occupies less space, and facilitates integration within the chassis 24.

[0027] Furthermore, the water pump outlet 9 and the return liquid assembly inlet 10 are located on the same side of the water tank 1.

[0028] The water pump outlet 9 and the return liquid component inlet 10 are located on the same side of the water tank 1. This allows the components connecting the water pump 3 and the return liquid component 2 to be located on one side of the water tank 1. For example, the water pump 3 and the return liquid component can be connected to the liquid cooling component 25 respectively. Thus, the channels of the liquid cooling component 25 for connecting the water pump 3 and the channels for connecting the return liquid component 2 can be located on one side of the water tank 1. This facilitates connecting the water pump 3 and the return liquid component 2 to the liquid cooling component 25 respectively. Furthermore, having all the channels located on one side of the water tank 1 makes it easier to organize and arrange them, thereby improving the space utilization efficiency within the chassis 24 and making it easier to integrate this device into the chassis 24.

[0029] Furthermore, the water tank outlet 7, the water pump inlet 8, the water pump outlet 9, and the return liquid assembly inlet 10 are located on the same side of the water tank 1.

[0030] By placing the water tank outlet 7 and the water pump inlet 8 on one side of the water tank 1, the length of the pipe connecting the water tank 1 and the water pump 3 is shortened, thereby improving the integration of the device.

[0031] By placing the water tank outlet 7, water pump inlet 8, water pump outlet 9, and return liquid assembly inlet 10 on the same side of the water tank 1, the path of the cooling medium from the water tank outlet 7 to the water pump outlet 3 is shortened, reducing the suction head loss of the water pump 3, lowering the energy consumption of the water pump 3, and reducing operating costs. Furthermore, the shorter piping significantly saves installation space between the water pump 3 and the water tank 1, improving the integration of the device.

[0032] Furthermore, the inlet 10 of the return liquid assembly is positioned towards the center of the water tank 1.

[0033] The return liquid assembly 2 may include a return liquid channel, and the contact surface between the return liquid channel and the water tank 1 may be a plane, so as to facilitate the integration of the return liquid channel into the water tank 1.

[0034] The return channel can be curved. For example, as shown in the figure, the inlet of the return channel is set upwards and the middle extends along the water tank 1.

[0035] The water tank outlet 7 can be located in the middle of the water tank 1, that is, the water inlet of the return channel is set towards the water tank outlet 7.

[0036] The advantage of this arrangement is that it makes the various channels on this side of the water tank 1 more concentrated (for example, the channel connecting the inlet of the return liquid assembly 2 can be closer to the channel connecting the inlet of the water pump 3 and the outlet of the water tank 1), reducing the space occupied when the device is integrated into the chassis 24.

[0037] Furthermore, along the third direction, the water tank inlet 12 and the water tank outlet 7 are respectively located on both sides of the water tank 1, and the outlet of the return channel and the water tank inlet 12 are located on the same side. The third direction can be perpendicular to the thickness direction of the water tank 1, and the third direction can be the direction shown by the X-axis in the figure.

[0038] The advantage of this arrangement is that the pipes of water tank 1 are distributed on both sides of water tank 1 along the third direction, while there are no pipes on both sides of the thickness direction of water tank 1. This makes it easy to integrate water tank 1 into the edge of chassis 24 without taking up too much installation space inside chassis 24.

[0039] Furthermore, the water pump 3 is provided with a discharge assembly, which includes a discharge channel 6, a first channel 14, and a second channel 16. The discharge channel 6 includes a first wall 13 and a second wall 20 disposed opposite to each other. The first wall 13 includes a first surface facing the water pump outlet 9. The first channel 14 is disposed on the first surface for communicating with the water pump outlet 9, and the second channel 16 is disposed on the first surface for discharging the medium.

[0040] The cooling medium output by water pump 3 enters the first channel 14, then enters the discharge channel 6, and is finally discharged from the second channel 16.

[0041] The discharge channel 6 allows the second channel 16 to be spaced a certain distance from the water pump outlet 9, making it easier to connect other components to the water pump 3.

[0042] The first wall 13 and the second wall 20 are arranged opposite to each other, so that the discharge channel 6 is flat, which ensures the conveying capacity of the discharge channel 6 and reduces the space occupied by the discharge channel 6.

[0043] The first channel 14 can be detachably connected to the water pump outlet 9. For example, the first channel 14 can be provided with a push ring 15, and a threaded sleeve 22 can be fitted onto the first channel 14. The threaded sleeve 22 abuts against the side of the push ring 15 away from the water pump outlet 9 (a boss can be provided on the inner circumferential wall of the threaded sleeve 22, and the boss abuts against the push ring 15). The threaded sleeve 22 can be threadedly connected to the water pump outlet 9. When the threaded sleeve 22 is tightened, the threaded sleeve 22 applies a force towards the water pump outlet 9 to the push ring 15, so that the first channel 14 can be tightly connected to the water pump outlet 9. The advantage of this connection is that the orientation of the discharge channel 6 can be adjusted as needed.

[0044] The first channel 14 and the second channel 16 are located on the same side of the discharge channel 6, which further increases the channel concentration at the water tank outlet 7.

[0045] Furthermore, the discharge channel 6 also includes a side skirt wall 19, which is arranged circumferentially around the first wall 13, and the second wall 20 is connected to the side skirt wall 19.

[0046] Under the action of the side skirt wall 19, the first wall 13, the second wall 20, and the side skirt wall 19 can form a cavity. At the same time, by adjusting the size of the side skirt wall 19, the discharge channel 6 can form a flat structure.

[0047] Furthermore, the discharge assembly also includes a docking part 21, which is provided with a through channel. A second channel 16 passes through the through channel, and an extension ring 17 is provided at the end of the second channel 16 away from the first surface. The docking part 21 abuts against the side of the extension ring 17 near the first surface.

[0048] The inner peripheral wall of the passage may be provided with a boss, which is used to abut against the expansion ring 17.

[0049] The docking part 21 is used to connect other channels to the second channel 16.

[0050] Specifically, the channel that is connected to the second channel 16 can also be provided with a docking part 21. When the two are connected, the docking parts 21 can be connected by bolts or screws. When the docking parts 21 are tightly attached, the docking parts 21 apply force to the expansion ring 17. That is, the docking parts 21 can apply a force to make the two channels close together, so that other channels can be connected to the second channel 16.

[0051] Furthermore, the side of the extension ring 17 away from the first surface is provided with a receiving recess 18, which is used to receive the seal.

[0052] The receiving recess 18 can be used for the insertion of a channel that mates with the second channel 16, i.e., the inner diameter of the channel is larger than the outer diameter of the second channel 16. When mates, the channel is inserted into the receiving recess 18.

[0053] The recess 18 can also be used to accommodate a seal, which can seal the gap between the channels.

[0054] Of course, other channels in this application embodiment may also be provided with seals to increase the sealing performance.

[0055] Furthermore, the water tank 1 is equipped with a self-relieving pressure component 4.

[0056] The self-relieving pressure component 4 is used to detect the pressure in the water tank 1. When the pressure is too high, the self-relieving pressure component 4 can automatically release the pressure. For example, the self-relieving pressure component 4 can be a pressure relief valve.

[0057] Furthermore, the water tank 1 may be equipped with a level gauge 5 for detecting the liquid level in the water tank 1.

[0058] The level gauge 5 can be electrically connected to the processor, which controls the operation of the level gauge 5 and receives data from it. The specific principles, programming code, and connection circuits of the level gauge 5 being controlled by the processor are well known to those skilled in the art and will not be described in detail here.

[0059] On the other hand, this application embodiment also provides a device, including a chassis 24, a liquid cooling component 25 and a heat exchange component 26 housed in the chassis 24, and also including the self-circulating liquid supply assembly 23 in the chassis as described in the above embodiment. In the self-circulating liquid supply assembly 23, the outlet 11 of the return liquid assembly is connected to the inlet of the heat exchange component 26, the outlet of the heat exchange component 26 is connected to the inlet 12 of the water tank, the outlet 9 of the water pump is connected to the inlet of the liquid cooling component 25, and the outlet of the liquid cooling component 25 is connected to the inlet 10 of the return liquid assembly.

[0060] The liquid cooling component 25 can be used to cool components within the chassis 24. For example, the liquid cooling component 25 can be a liquid cooling plate, which is a mature product in the prior art. The heat exchange component 26 is used to cool the cooling medium. For example, the heat exchange component 26 can be a heat exchange plate, which is a mature product in the prior art.

[0061] During operation, the water pump 3 draws out the cooling medium from the water tank 1, and the cooling medium enters the liquid cooling plate, so that the liquid cooling plate can cool the components inside the chassis 24. The cooling medium discharged from the liquid cooling plate enters the return liquid assembly 2, and then enters the heat exchange plate, where it is cooled. The cooled medium then flows back into the water tank 1.

[0062] The arrangement of the heat-generating components and the liquid cooling plate within the chassis 24 can refer to existing technologies. The circulation piping for the heat exchange medium in the heat exchange plate can also be configured according to existing technologies. This application does not improve upon the aforementioned two parts, and therefore will not elaborate further.

[0063] The self-circulating coolant supply component 23 is located inside the chassis 24, allowing the chassis 24 to achieve internal coolant self-circulation without external power.

[0064] like Figure 8 The present invention also proposes a self-circulating liquid supply method within a chassis, comprising the following steps: Step 1: Start-up of self-circulating liquid supply and media delivery: When water pump 3 is started, it generates negative pressure. The cooling medium in water tank 1 is drawn into water pump 3 through water tank outlet 7, which is connected to water pump inlet 8. After being pressurized by water pump 3, it is discharged from water pump outlet 9. The pressurized cooling medium enters the first channel 14 from water pump outlet 9 and flows into the discharge channel 6 formed by the first wall 13, the second wall 20 and the side skirt wall 19. After being buffered and stabilized by discharge channel 6, it is stably output from the second channel 16 and sent to the inlet of liquid cooling component 25 through docking part 21, thus completing the pressurized delivery of cooling medium.

[0065] Step 2: Heat absorption, heat exchange, and medium reflux circulation: After the cooling medium enters the liquid cooling component 25, it completes forced convection heat exchange with the heat-generating devices in the chassis 24, absorbing the heat generated by the operation of the devices and achieving cooling and temperature reduction of the heat-generating devices. After absorbing heat, the high-temperature cooling medium flows out from the outlet of the liquid cooling component 25, enters the return liquid component 2 through the return liquid component inlet 10 set towards the middle of the water tank 1, and after being guided by the flow channel of the return liquid component 2, it is discharged from the return liquid component outlet 11 and sent to the inlet of the heat exchange component 26. After the high-temperature cooling medium enters the heat exchange component 26, it completes heat exchange with the external environment, releases heat and lowers its temperature, forming a low-temperature cooling medium. The low-temperature cooling medium flows out from the outlet of the heat exchange component 26 and flows back into the water tank 1 through the water tank inlet 12, completing a complete self-circulating liquid supply process. Water pump 3 runs continuously, repeating the self-circulating liquid supply process to achieve continuous closed-loop self-circulation of the cooling medium within the chassis 24.

[0066] Step 3: Real-time monitoring of system operation status: During the system's cyclic operation, the level gauge 5 installed on the water tank 1 monitors the cooling medium level in the water tank 1 in real time. When the level is lower than the minimum safe level, a low level alarm signal is triggered to remind the operator to add cooling medium and ensure the safe operation of the water pump 3. The self-relieving pressure relief component 4 installed on the water tank 1 monitors the internal pressure of the water tank 1 in real time. When the pressure in the water tank 1 exceeds the preset safety threshold, the self-relieving pressure relief component 4 automatically opens to release the excess pressure in the water tank 1. After the pressure drops back to the safe range, the self-relieving pressure relief component 4 automatically closes, realizing automatic pressure relief protection during system operation. The water pump 3 adjusts its operating power according to the load changes of the heat-generating components. Through its vertically distributed integrated structure and the centralized pipeline interfaces on the same side, it always maintains a stable liquid supply state with low suction head loss and low flow resistance, adapting to the cooling needs of different load conditions within the chassis 24.

[0067] Step 4: System shutdown and pressure maintenance: Upon receiving the shutdown command, water pump 3 stops running, the closed-loop self-circulating liquid supply process terminates, and the cooling medium in water tank 1, return liquid assembly 2, liquid cooling component 25, heat exchange component 26 and connecting pipeline remains in a static pressure-holding state. In the shutdown state, the pressure in the system is maintained stable by the self-relieving pressure component 4, and the liquid level is continuously monitored by the liquid level gauge 5, which facilitates the operator to perform maintenance operations such as replenishing the cooling medium, inspecting the pipeline, and replacing the components.
