Compact ultrathin water pump

Abstract

The invention discloses a compact ultrathin water pump which comprises a water pump body. The water pump body comprises a top cover, a pump shell and a base assembly. An impeller assembly is arranged in the pump shell, and a stator assembly is arranged on the base assembly. A water inlet connector is arranged on one side of the pump shell, and a water outlet connector is arranged on the other side of the pump shell. A first cavity is formed between the top cover and the pump shell, the first cavity comprises an annular water storage chamber separately arranged on the side face of the pump shell and an annular suction chamber arranged on the pump shell and communicated with the annular water storage chamber, and the water inlet connector is communicated with the annular water storage chamber. A second cavity is formed between the pump shell and the base assembly, an annular water pumping chamber is arranged on the outer side of the second cavity, the impeller assembly is arranged in the middle of the second cavity, the annular suction chamber is communicated with the annular water pumping chamber, and the annular water pumping chamber is communicated with the water outlet connector. The axial size of the water pump is obviously reduced, a water tank is integrated into the design of the water pump, and the compactness of the water pump is improved.

Description

technical field [0001] The invention relates to the technical field of water pumps, in particular to a compact ultra-thin water pump. Background technique [0002] There are more and more demands for ultra-thin water pumps in the industry. In order to reduce the axial length, conventional centrifugal pumps generally adopt the following flow channel design. Generally, the cooling water first flows into the circular water inlet horizontally, and then turns 90 degrees to axially flow into the impeller. , and finally flow out from the side of the impeller. However, in this conventional design, the circular water inlet is on the upper part of the water pump, so that its axial size cannot be further reduced due to the size of the water inlet flow channel. [0003] like figure 1 and 2 As shown, it is a conventional centrifugal pump design. When conventional centrifugal pumps are used, a water tank needs to be added to the external water circuit to store cooling water. Due to the...

Problems solved by technology

However, in this conventional design, the circular water inlet is on the upper part of the water pump, so its axial size is limited by the size of the water inlet channel and cannot be further reduced.

[0003] like figure 1 and 2 As shown, it is a conventional centrifugal pump design. When a conventional centrifugal pump is used, a water tank needs to be added to the external water circuit to store cooling water. Due to the existence of the water tank, the entire liquid cooling system is relatively large.

At the same time, the connection between the water tank and the water pump is difficult to ensure watertightness; image 3 As shown, there is also an integrated water pump in the prior art, and its water tank is designed in series with the water pump body. Although it is convenient to use, this series connection leads to a further increase in the axial dimension of the water pump.

[0004] Therefore, the existing conventional water pumps are increasingly unable to meet the industry's requirements for the size and compactness of liquid cooling systems and ultra-thin water pumps
