Description

Technical Field

[0001] This invention belongs to the field of computer water cooling technology, specifically relating to a high-flow-rate silent circulating pump with a water tank. Background Technology

[0002] When traditional high-power electronic products use water-cooling systems, the water pump is just a simple water pump, and the water tank needs to be external. This makes it inconvenient for non-professional users and for mass production to add liquid and bleed the air from the water-cooling system, resulting in poor heat dissipation.

[0003] Currently, some products integrate the water tank and pump into a single structure. This type of integrated water tank and pump works normally at a flow rate of 2-3 L / min, but when the flow rate exceeds 4-5 L / min, a vortex forms in the negative pressure zone at the pump inlet, affecting its operation. Patent application number 202220304851.5 discloses a high-power, silent integrated water tank and pump with an optimized structure. A filter screen is installed between the water tank and pump housing, which can solve the vortex problem at low flow rates (4-12 L / min). However, once the flow rate exceeds 14 L / min, a vortex phenomenon, known as a water-dragging phenomenon, forms in the negative pressure zone at the pump inlet. Traditional solutions include: first, increasing the size of the water tank to reduce or eliminate the potential energy of the water-dragging phenomenon; second, using filter cotton inside the water tank. However, these methods still require increasing the size of the water tank to eliminate the water-dragging phenomenon. Summary of the Invention

[0004] This invention provides a high-flow silent circulating pump with a water tank. By installing a perforated water distributor at the connection between the pump chamber inlet and the water tank, water enters the pump chamber inlet from the side of the water distributor, thus solving the vortex phenomenon of high-power water pumps.

[0005] To achieve the above objectives, the technical solution of the present invention is:

[0006] A high-flow silent circulating pump with a water tank includes a pump and a water tank. A perforated water distributor is provided at the connection between the pump inlet of the pump chamber and the water tank. A return water chamber is provided between the pump inlet of the pump and the water distributor. The water distributor is arranged in layers, so that water enters the pump inlet from the side of the return water chamber and / or enters the water tank from the return water chamber and then enters the pump inlet from the side of the water distributor.

[0007] Preferably, the water distributor includes a first water distribution section and a second water distribution section, the second water distribution section is columnar, and the first water distribution section is arranged circumferentially along the second water distribution section to form a two-layer structure.

[0008] Preferably, the first water distribution section is provided with several small holes, and the first water distributor is circumferentially connected to the middle of the second water distribution section.

[0009] Preferably, the second water distribution section has several vertically arranged elongated holes on its side wall, and the top is a closed structure.

[0010] Preferably, the second water distribution section is installed on the partition of the return water chamber, and the interior of the second water distribution section forms a buffer chamber with the pump chamber inlet.

[0011] Preferably, the water tank cover is provided with a water tank inlet, and a water guide pipe is connected below the water tank inlet.

[0012] Preferably, the tank cover is also provided with a liquid filling port and a temperature sensing probe hole.

[0013] Preferably, the water pump outlet is funnel-shaped, gradually widening from the inside out.

[0014] Preferably, the water pump is threadedly connected to the water tank.

[0015] The principle of bubble elimination in this application is as follows: After the water entering the pump inlet enters the return water chamber, the impact force of the returning water is relatively large. If it directly enters the water tank, a large number of bubbles will be generated. If the returning water carries bubbles, the bubbles will also directly enter the pump. The small holes on the first water distribution section buffer and disperse the returning water, allowing the bubbles to enter the space above the water storage tank, thus achieving the function of venting.

[0016] The beneficial effects of this invention are:

[0017] 1. This invention combines a water pump and a water tank, adding a water distributor with a grid at the inlet to allow water to enter from the side. The water distributor is divided into two layers, allowing water to enter simultaneously from the return water chamber below the first water distribution section and the water storage chamber of the water tank. Because the water distributor has vertical holes, it achieves a super large water intake capacity, solves the negative pressure problem at the inlet of a high-flow water pump, eliminates the water suction phenomenon, ensures that no bubbles are generated, and prevents the water cooling system from being affected by air, thus preventing poor heat dissipation performance. Without increasing the volume of the water tank, it solves the vortex problem of water suction caused by the integrated water pump and water tank in high-power water pumps.

[0018] 2. The invention has a small overall size, a built-in transparent water tank for easy observation of the liquid level, and a built-in filling port for convenient liquid addition. The pump body is securely connected, improving reliability. Attached Figure Description

[0031] See Figures 1 to 6 A high-flow-rate, silent circulating pump with a water tank includes a pump 10 and a water tank 20, which are integrally formed. The water tank is positioned above the pump, and the pump is threadedly connected to the water tank. The water tank is made of a transparent material, such as acrylic tubing, and contains a water storage chamber 201 for easy observation of the water level. The pump has a pump inlet 101 and a pump outlet 102, and consists of a motor 103, an impeller 104, a pump head 105, and a bottom cover 107. A perforated water distributor 30 is provided at the connection between the pump inlet 110 and the water tank of the water pump. A return water chamber 108 is provided between the pump inlet 101 and the water distributor 30. A partition 109 is provided between the return water chamber 108 and the pump inlet 110. The partition 109 is circumferentially arranged around the pump inlet 110. The water distributor 30 is fixed on the partition 109, that is, the water distributor 30 is installed above the pump inlet 110. Both the pump inlet 110 and the return water chamber 108 are located on the pump head 105. The motor drives the impeller to rotate, and the impeller is located below the pump inlet. The water distributor 30 is arranged in layers, so that water enters the pump inlet 110 from the side of the return water chamber 108 and / or enters the water tank from the return water chamber 108 and then enters the pump inlet 110 from the side of the water distributor 30. This structural design solves the negative pressure problem at the inlet 110 of the high-flow pump chamber, eliminates the water suction phenomenon, ensures that no bubbles are generated, and keeps the heat dissipation performance of the water cooling system unaffected.

[0032] Furthermore, the water distributor 30 includes a first water distribution section 301 and a second water distribution section 302. The second water distribution section 302 is columnar, and the first water distribution section 301 is arranged circumferentially along the second water distribution section 302, forming a two-layer structure. Specifically, the first water distribution section 301 is provided with a plurality of small holes 303, and the first water distributor 30 is circumferentially connected to the middle or slightly below the middle of the second water distribution section 302.

[0033] During use, water enters the water pump inlet 101 and then enters the return water chamber 108. The water in the return water chamber 108 enters the pump chamber inlet 110 laterally or enters the water storage tank 201 of the water tank through the mesh of the first water distribution section 301. The mesh of the first water distribution section 301 can eliminate water vapor bubbles and air in the return water. The dense small holes 303 on the first water distribution section 301 divide the return water into small segments and disperse the air in the return water, discharging it upwards into the water storage tank 201.

[0034] Furthermore, the second water distribution section 302 has several vertically arranged elongated holes 304 on its side wall, and the top is a closed structure so that water can only enter from the side of the second water distribution section 302; the water distributor 30 is configured as two layers, with the second water distribution section 302 having vertically arranged elongated holes 304 on its side, which are respectively placed at the upper and lower ends of the first water distribution section 301. Water in the water storage tank 201 in the water tank enters the pump chamber inlet 110 from the upper end of the second water distribution section 302, and water in the return water chamber 108 enters the pump chamber inlet 110 from the lower end of the second water distribution section 302. The height of the second water distribution section 302 is determined according to the maximum flow rate of the water pump.

[0035] In this application, the second water distributor 302 is installed on the partition 109 of the return water chamber 108, and a buffer chamber is formed between the interior of the second water distributor 302 and the pump inlet 110. Through the structural arrangement of the first water distributor 30 and the second water distributor 30 and the water inlet method, the suction phenomenon caused by the negative pressure of the high-power, high-flow water pump inlet 101 can be effectively eliminated, ensuring that the liquid entering the pump chamber is free from interference from air bubbles, effectively improving the heat dissipation efficiency of the water cooling system, and effectively reducing the cavitation problem of air bubbles on the water pump impeller 104.

[0036] Furthermore, the water tank cover is provided with a water tank inlet 202, and a water guide pipe 203 is connected below the water tank inlet 202. The water tank inlet 202 allows users to flexibly arrange the water circuit. The water tank inlet 202 is connected to a water guide pipe 203, which leads the return water to the lower part of the water storage tank 201, placing it in front of the water level to prevent the impact caused by excessive return water flow.

[0037] Furthermore, the box cover is also provided with a liquid filling port 204 and a temperature sensor probe hole 205; the liquid filling port 204 makes it convenient for users to add liquid at any time.

[0038] Furthermore, the water pump outlet 102 is in the shape of a trumpet that gradually expands from the inside out.

[0039] The above description is merely an embodiment of the present invention and does not limit the patent scope of the present invention. Any equivalent structural or procedural transformations made based on the content of the present invention specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of the present invention.
