Description

Technical Field

[0001] The utility model relates to the technical field of liquid cooling radiating liquid pumps, in particular to an integrated silent liquid pump. Background Art

[0002] As the power consumption of chip cooling is increasing, water cooling is required in many scenarios to meet the cooling demand. However, since water cooling is more complex than air cooling, it is particularly important to simplify the installation. Therefore, a water tank pump for water cooling with a relatively simple structure is needed. In the existing water tank pumps for water cooling, the filter mesh cover is arranged on the upper side of the water inlet of the pump cavity. The filter mesh will block the water flow entering the water inlet of the pump cavity, easily resulting in untimely water flow entering the water inlet of the pump cavity, thus affecting the flow rate of the water tank pump. For example, the patent document CN216820495U discloses a high-power silent integrated water tank pump with an optimized structure. Therefore, it is necessary to design an integrated silent water tank pump that can avoid the influence of the filter mesh on the water flow entering the water inlet of the pump cavity. Summary of the Utility Model

[0003] In view of the above problems in the prior art, the present application proposes an integrated silent liquid pump that can avoid the influence of the filter mesh on the water flow entering the water inlet of the pump cavity.

[0004] The utility model provides an integrated silent liquid pump, which comprises a buffer tank and a liquid pump motor. The liquid pump motor includes an outer shell and a liquid pump assembly installed in the outer shell. The buffer tank is installed above the outer shell. The outer shell is provided with a liquid inlet joint and a liquid outlet joint. A mixing cavity communicated with the liquid inlet joint is arranged in the outer shell. A filter mesh is covered on the mixing cavity. The liquid outlet end of the liquid pump assembly is communicated with the liquid outlet joint. Liquid enters the mixing cavity from the liquid inlet joint for buffering, then enters the buffer tank through the filter mesh, and finally enters the liquid pump assembly for pressurization and flows out from the liquid outlet joint.

[0005] As a further improvement of the above technical solution:

[0006] In the above integrated silent liquid pump, further, a plurality of positioning columns are arranged at intervals on the outer edge of the mixing cavity in the outer shell. A liquid pump cover body is arranged in the outer shell. The liquid pump cover body is provided with a liquid inlet. A positioning step is arranged on the outer edge of the liquid pump cover body. The filter mesh is placed on the positioning columns and the positioning step in a positioned manner.

[0007] In the above integrated silent liquid pump, further, liquid blocking plates are arranged on both opposite sides of the liquid pump cover body. The two liquid blocking plates, the inner wall of the outer shell and the outer side wall of the liquid pump cover body form the mixing cavity.

[0008] For the above-mentioned integrated silent liquid pump, further, the liquid pump assembly includes a volute, a liquid pump impeller, and a liquid pump motor. The outer casing and the volute are sealed by a sealing ring, and the liquid inlet is communicated with the liquid inlet end of the liquid pump impeller.

[0009] For the above-mentioned integrated silent liquid pump, further, a clamping step is circumferentially provided on the outer edge of the outer casing, and the buffer box can be hermetically clamped on the clamping step.

[0010] For the above-mentioned integrated silent liquid pump, further, liquid permeation holes are provided on the upper surface of the buffer box, and a plugging cover is detachably installed on the liquid permeation holes.

[0011] The above technical features can be combined in various suitable ways or replaced by equivalent technical features as long as the purpose of the present utility model can be achieved.

[0012] Compared with the prior art, the integrated silent liquid pump provided by the present utility model has at least the following beneficial effects: When the integrated silent liquid pump works, liquid enters the mixing chamber from the liquid inlet joint. The mixing chamber can release the kinetic energy of the high-speed liquid here, and then enters the buffer box through the filter screen. The filter screen buffers the liquid entering the buffer box, so that the liquid reduces the impact force, eliminates the bubbles brought by the impact force, and avoids the performance attenuation and unstable noise caused by the liquid pump assembly sucking bubbles from the buffer box. The liquid pump assembly after being buffered by the filter screen can effectively improve the product performance consistency and noise consistency, and finally enters the liquid pump assembly for pressurization and flows out from the liquid outlet joint. For this integrated silent liquid pump, the liquid entering the buffer box directly enters the liquid pump assembly, thus avoiding the influence of the filter screen on the water flow entering the water inlet of the pump chamber.
