Description

Technical Field

[0001] The present invention relates to the technical field of computer heat dissipation, and in particular to a water tank integrated pump and a water circuit system suitable for closed water circulation of computer heat dissipation. Background Art

[0002] In the fields of laser projection, servers, computers, mobile communications, medical systems, power electronics, etc., high requirements are usually placed on thermal performance, spatial integration, and closed-loop heat dissipation methods to ensure that the device or equipment operates normally and stably during actual use.

[0003] During the use of electronic equipment such as computers, in order to ensure the operating environment of the host, it is necessary to perform temperature detection and cooling inside the host case. In order to improve the cooling effect, water cooling has better cooling characteristics than traditional air cooling, and is quieter to use, and is widely used. For example, patent number CN 118244859A discloses an easy-to-install computer hardware temperature automatic adjustment and detection device. Computer water-cooled radiators are generally composed of a water cooling head, a water pipe, a water pump, a water tank, and a cold row. When in use, the water cooling head is responsible for contacting the heat-generating hardware and absorbing heat. The water pump and the water tank are placed inside the host case to circulate and store the cooling water respectively, and the cold row is installed at the heat dissipation port of the host case to cool the circulating water.

[0004] However, during the assembly process of the closed water circulation system, it is inevitable that there will be leakage and evaporation to varying degrees at the joints of the parts; and when filling the water circulation fluid, there is also the phenomenon of insufficient filling, which may cause air to exist in the closed water circulation system. The air in the closed water circuit passes through the water pump impeller, which will produce obvious bubbles and abnormal noise. In addition, the separate water pump and water tank structure often requires more space for arrangement, making it difficult to reduce the occupied space of the water system, and the separate water pump and water tank need to be connected separately, which greatly increases the possibility of leakage or evaporation of circulating water. Therefore, further improvement is needed. Summary of the invention

[0030] Example

[0031] Reference Figures 1 to 4 The present invention proposes a water tank integrated pump suitable for a closed water circulation of computer heat dissipation, comprising: a housing 10, an impeller 20, a motor 30 and a flow blocking member 40;

[0032] The shell 10 is provided with a water pump chamber 50 and a water tank chamber 60 which are interconnected; the water tank chamber 60 is connected with a water inlet 11; the water pump chamber 50 is connected with a water outlet 12; the impeller 20 is arranged in the water pump chamber 50 and connected with the motor 30; the baffle 40 is arranged in the water tank chamber 60; the baffle 40 is provided with a first baffle plate 41, and the first baffle plate 41 is close to the water inlet 11, which is used to delay the water flow directly flowing toward the water pump chamber 50.

[0033] In the present invention, the water tank and the water pump are integrated into a single housing 10; wherein the water tank cavity 60 and the water pump cavity 50 are interconnected, which can reduce the additional arrangement of the water tank accessories in the water system and reduce the space arrangement requirements of the waterway. In addition, a flow blocker 40 is arranged in the water tank cavity 60, and the first flow blocker 41 of the flow blocker 40 is close to the water inlet 11, which can prevent the water flow carrying air directly to the water pump cavity 50; the water flow can be blocked by the first flow blocker 41, and the flow rate of the water flow can be reduced. When there is air in the waterway, the bubbles in the water flow will be blocked by the flow blocker on the side away from the water pump cavity 50, so as to achieve the effect of defoaming and silencing. After the defoamed water flow enters the water pump cavity 50, it is pumped out from the water outlet 12 by the water outlet 12 of the impeller 20.

[0034] Specifically, the shell 10 of the present invention is arranged vertically, the water inlet 11 is located above the water tank cavity 60, and the water pump cavity 50 is located below the water tank cavity 60; under the action of gravity, the bubbles blocked by the baffle 40 will accumulate above the water tank and the baffle 40.

[0035] In this embodiment, the baffle 40 is provided with a second baffle disc 42, which is separated between the water pump chamber 50 and the water tank chamber 60; the second baffle disc 42 is provided with a flow hole 43 connecting the water pump chamber 50 and the water tank chamber 60. The second baffle disc 42 can prevent the water flow in the water tank chamber 60 from directly entering the water pump chamber 50, and needs to be further blocked to enter the water pump chamber 50 through the flow hole 43 with a smaller aperture. The second baffle disc 42 can achieve a secondary flow blocking effect, further blocking the phenomenon of bubbles entering the water pump chamber 50 with the water flow, and achieving a secondary flow blocking and defoaming effect.

[0036] Specifically, in order to allow the first spoiler disk 41 and the second spoiler disk 42 to form an integrated and stable single element, the first spoiler disk 41 and the second spoiler disk 42 are directly provided with a connecting support wall 44 .

[0037] Furthermore, a plurality of connecting support walls 44 are provided along the circumferential direction, and the connecting support walls 44 are provided close to the inner wall of the water tank cavity 60. The connecting support walls 44 are close to the inner wall of the water tank cavity 60, and the flow blocking member 40 abuts against the side wall of the water tank cavity 60, which can reduce the sound when the water flow hits the flow blocking member 40.

[0038] In this embodiment, in order to facilitate the stability of water flow through the water tank cavity 60 and the water pump cavity 50, and to facilitate the baffle 40 to be directly placed in the water tank cavity 60; the water tank cavity 60 is a circular channel structure; the first baffle plate 41 and the second baffle plate 42 are disc-shaped and are respectively arranged at the opposite ends of the water tank cavity 60.

[0039] Specifically, the water pump chamber 50 is a circular channel structure, and the aperture of the water pump chamber 50 is smaller than the aperture of the water tank chamber 60; the second spoiler 42 includes two coaxial staggered frustums, one frustum can be set against the end wall of the water pump chamber 50, and the other frustum can extend into the water pump chamber 50 and fit the inner wall of the water pump chamber 50. The two-layer frustum-shaped second spoiler 42 can be set against the end wall of the water pump chamber 50, and can extend into the inner wall of the water pump chamber 50 for sealing, so as to ensure the sealing and flow blocking effect of the second spoiler 42, and the water flow can only enter the water pump chamber 50 through the flow hole 43, and the impeller can be prevented from moving up and down.

[0040] In this embodiment, the outer periphery of the first baffle plate 41 can fit the inner wall of the water tank cavity 60; the outer periphery of the first baffle plate 41 is provided with a plurality of inwardly recessed flow guide grooves 45. The plurality of flow guide grooves 45 allow the water flow blocked by the first baffle plate 41 to be dispersed into several sections and enter the water tank cavity 60, so that it is difficult for a small water flow to carry bubbles through the flow guide grooves 45, thereby effectively improving the effect of blocking bubbles and defoaming.

[0041] Specifically, the outer periphery of the first baffle plate 41 is provided with a plurality of support protrusions 46 extending in the axial direction; the outer periphery of the support protrusions 46 can be set against the inner wall of the water tank cavity 60; the guide groove 45 is located between two adjacent support protrusions 46; and the guide groove 45 is provided with an inclined guide surface 47. Through the support protrusions 46, more contact support surfaces can be provided to fit the inner wall of the water tank cavity 60, so that the installation of the baffle 40 is more stable. In addition, the guide groove 45 is provided with an inclined guide surface 47, which guides the water flow obliquely to the inner wall of the water tank cavity 60, so that the dispersed water flow can be guided to the inner wall of the water tank cavity 60 in an inclined direction, and the dispersed water flow flows more smoothly; and after the water flow passes through the guide groove 45, it will flow in line with the inner wall of the water tank cavity 60, so as to achieve further deceleration of the diversion, so as to keep the bubbles out of the water flow above the water tank.

[0042] In some implementations, a cover 70 is installed in the water tank cavity 60 ; the support protrusion 46 can abut against the cover 70 . The cover 70 can press the flow blocking member 40 into the water tank cavity 60 through the support protrusion 46 .

[0043] Furthermore, in order to improve the sealing effect of the cover 70 , the cover 70 is installed with a plurality of sealing rings 71 .

[0044] The present invention also provides a water system, comprising the above-mentioned water tank integrated pump.

[0045] It should be noted that in order to achieve the air bubble flow resistance and gather on the side of the water tank cavity 60 away from the water pump cavity 50, the integrated pump as a whole needs to be arranged vertically up and down in the water system, and the water tank cavity 60 is located above the water pump box. In addition, when the amount of air generated in the water path is too much and exceeds the volume of the entire water tank cavity 60, the air bubbles will still enter the water pump cavity 50, resulting in noise.

[0046] Of course, the present invention is not limited to the above-mentioned embodiments, and those skilled in the art may make equivalent modifications or substitutions without violating the spirit of the present invention. These equivalent modifications and substitutions are all included in the scope defined by the claims of this application.
