Embodiment 1

[0040] Please refer to Figure 5 to Figure 8, Embodiment 1 of the present invention provides a new type of impeller, including an impeller body 8, the impeller body 8 includes a hub 9, the side of the hub 9 is equipped with blades 10, and the blades 10 are directly connected to the side of the hub 9, so The bottoms of the blades 10 are connected together to form a ring shape and directly connected to the side of the hub 9. The hub 9 and the blades 10 are integrally formed. The design or arrangement of the blades 10 can effectively reduce the axial dimension of the impeller body 8, thereby reducing the The axial dimension of the micro water pump can reduce the axial dimension of the micro water pump by at least 30%.

[0041] In the present invention, the position of the blade 10 is transferred from the top of the hub 9 to the side of the hub 9 and the blade 10 is directly connected to the side of the hub 9, which can achieve a better hydrodynamic effect and improve the inner sp...

Embodiment 2

[0050] Please refer to Figure 9 to Figure 13 , Embodiment 2 of the present invention provides a new type of micro water pump, including a micro water pump body 1, the micro water pump body 1 includes a housing 2, the housing 2 is provided with a water inlet 3 and a water outlet 4, and the water inlet 3 Connect to the horizontal water inlet channel 5, the horizontal water inlet channel 5 is connected to the impeller channel 7, one side of the impeller channel 7 is connected to the horizontal water inlet channel 5, and the other side is connected to the horizontal water outlet channel 6, and the horizontal outlet channel 7 6 is connected to the water outlet 4, the central axis of the horizontal water inlet channel 5 and the central axis of the horizontal water outlet channel 6 are in the same plane, specifically, the central axis of the horizontal water inlet channel 5 and the central axis of the horizontal water outlet channel 6 are in the same plane In a plane with a flatness...

Abstract

The invention discloses a novel impeller and a miniature water pump comprising the same. The novel impeller comprises an impeller body; the impeller body comprises a hub, blades are arranged on the side face of the hub, the blades are directly connected to the side face of the hub, the hub and the blades are integrally formed, the diameter of the hub is D1, the diameter of the impeller body is D2, the ratio of the diameter D1 of the hub to the diameter D2 of the impeller body is larger than or equal to 80%, namely D1 / D2 is larger than or equal to 80%; and a permanent magnet is arranged in the impeller body, and the permanent magnet provides driving force for driving the impeller body to rotate. According to the impeller, the axial size the impeller is effectively reduced, and then the axial size of the miniature water pump is reduced, the rotating speed, power, flow and lift of the miniature water pump are effectively improved, the flowing direction of water flow can be conveniently switched, the application flexibility of the miniature water pump is improved, and it is guaranteed that the flow and lift performance is basically unchanged.

Description

technical field [0001] The invention relates to the technical field of micro water pumps for liquid cooling and heat dissipation, in particular to a novel impeller and a micro water pump containing the impeller. Background technique [0002] At present, the size of the electronic equipment system is shrinking day by day. The cooling fan needs to provide the highest heat dissipation performance in the limited installation space to meet the market demand. With the development of science and technology, the use of fans for heat dissipation is getting closer to the limit. In order to meet the industry's continuous requirements Due to the high demand for heat dissipation, micro-water pumps for liquid cooling and heat dissipation of electronic equipment have emerged as the times require. [0003] Existing conventional micro-pump impellers, such as figure 1 As shown, there are two design defects in the impeller of the micro water pump, the first: the blades are installed on the up...
