[0072] The detailed description and technical contents of this application are described below in conjunction with the accompanying drawings. However, the accompanying drawings are only provided for reference and illustration and are not intended to limit this application.

[0073] The present application provides an axial flow pump and a water cooling device having the axial flow pump, such as Figures 1 to 9 The axial flow pump of this application is shown as follows. Figure 10 The figure shows a water-cooled heat sink with an axial flow pump (hereinafter referred to as a water-cooled heat sink). Figure 10 The water-cooling heat dissipation device shown includes an axial-flow pump 100 , a water-cooling head 700 , a water-cooling radiator 800 , and a circulating water circuit (component symbols are not marked).

[0074] like Figures 1 to 9 As shown, the axial flow pump 100 of the present application includes: a casing 1, an impeller 2, a stator 3, a rotor 4 and a guide flow channel G.

[0075] The housing 1 can be a single-piece structure or a multi-piece structure and includes a housing body 11, a housing cover 12 and an inner cover 13. Taking the single-piece structure as an example, the housing 1 is provided with a guide channel G and has the following features: Figure 6 As shown, the housing 1 is provided with a chamber 16 and a stator slot 19 separated from each other, and the housing 1 is further provided with an inlet hole 1a and an outlet hole 1b. The chamber 16 is divided into a blade chamber 161 and a rotor chamber 162. The inlet hole 1a is connected to the rotor chamber 162, and the outlet hole 1b is connected to the blade chamber 161 via a guide channel G. Figure 6 The corresponding rotor chamber 162 is shown as surrounding. It should be noted that the suction hole 1a and the discharge hole 1b can be two holes opened on the housing 1, or can be two pipe openings extending from the two holes, and the present application does not limit this.

[0076] The impeller 2 is rotatably disposed in the chamber 16 and is defined as follows: Figure 7 The rotation axis L shown in the figure also defines an axial direction D1 parallel to the rotation axis L and a radial direction D2 perpendicular to the rotation axis L. The impeller 2 can rotate about the rotation axis L. The impeller 2 is provided with a plurality of diverter channels 25 and includes a hub 21 and a plurality of blades 22. The diverter channels 25 are connected between the suction port 1a and the blade chamber 161. The diverter channels 25 are connected to the rotation axis L. The blades 22 are connected to the hub 21 in a circular manner and surround the corresponding rotation axis L. The blades 22 are located in the blade chamber 161, and the hub 21 is located in the rotor chamber 162. Specifically, as shown in FIG. Figure 7 As shown, each blade 22 is connected to the end face of the hub 21, and each diversion channel 25 is opened in the hub 21. One end of the diversion channel 25 passes through the end face of the hub 21 (see Figure 3 ) and is located correspondingly between the two blades 22.

[0077] The stator 3 is disposed in the housing 1 corresponding to the stator slots 19, and the rotor 4 is disposed in the hub 21 and located in the rotor chamber 162, so that the stator 3 surrounds the rotor 4. Specifically, the rotor 4 is disposed in a wrapping manner on the hub 21.

[0078] As previously described, the guide channel G is disposed within the housing 1 and includes a guide inlet G11 and a guide outlet G21. The guide inlet G11 is disposed around all blades 22 in the radial direction D2 and communicates with the blade chamber 161. The guide outlet G21 communicates with the discharge hole 1b in the axial direction D1.

[0079] Specifically, the guide channel G is a spiral channel centered around the rotation axis L, with its outer diameter gradually decreasing from the blade chamber 161 toward the discharge port 1b. The aforementioned intake port 1a, discharge port 1b, and guide outlet G21 are all arranged along the axial direction D1; the guide inlet G11 is arranged along the radial direction D2.

[0080] By this, Figures 4 to 7 As shown, when the axial flow pump of the present application is started, the impeller 2 begins to rotate and draws water from the suction hole 1a; the drawn water enters each branch channel 25 and is driven by the impeller 2 to rotate together, and is discharged in a spiral shape along the radial direction D2 from between the two blades 22 in the blade chamber 161; the water exiting the impeller 2 then enters the guide inlet G11, and the spiral guiding effect of the guide channel G (with an outer diameter gradually decreasing) is used to change the water originally flowing along the radial direction D2 to flow along the axial direction D1, and the water is pumped out from the guide outlet G21 and the discharge hole 1b. This makes the present application an axial flow pump that can pump out water along the axial direction D1, that is, it has the axial flow effect of water entering and discharging along the axial direction D1, and is therefore suitable for electronic equipment with limited space.

[0081] In addition, as Figures 1 to 9 As shown, the housing 1 of the multi-piece structure is taken as an example, and as mentioned above, it includes a housing body 11, a housing cover 12 and an inner cover 13.

[0082] The guide channel G is divided into a front channel G1 and a rear channel G2. The front channel G1 has the aforementioned guide inlet G11, and the rear channel G2 has the aforementioned guide outlet G21. The shell body 11 is provided with the front channel G1 and has the aforementioned chamber 16 and suction port 1a. The inner cover 13 is provided with the rear channel G2 and covers the shell body 11 at the position corresponding to the blade chamber 161, so that the front channel G1 and the rear channel G2 are connected together to form the guide channel G. The blade chamber 161 is formed between the inner cover 13 and the shell body 11. The shell cover 12 has the aforementioned discharge port 1b. The shell cover 12 covers the inner cover 13 and is fixed to the shell body 11 in various ways, such as screwing or snapping, so that the inner cover 13 is fixed in the aforementioned position. A waterproof gasket 5 can also be provided between the shell cover 12 and the shell body 11 to ensure that the outer shell 1 has a waterproof effect between the shell cover 12 and the shell body 11.

[0083] It should be noted that the rotor chamber 162 is provided with a diverter frame 17 at the position corresponding to the suction port 1a. The diverter frame 17 is provided with a plurality of diverter holes 172 connected to the aforementioned diverter channels 25. The impeller 2 has a rotating shaft 23, the inner cover 13 is provided with a shaft connection portion 131, and the diverter frame 17 is also provided with a shaft connection portion 171. The rotating shaft 23 is connected between the two shaft connections 131 and 171. Figure 2 As shown, the hub 21 of the impeller 2 is provided with a diversion structure 211, the diversion structure 211 is provided with the aforementioned diversion channels 25 and has a sleeve column 2111, and the shaft 23 is also as shown. Figure 6 As shown, it is inserted into the socket column 2111.

[0084] like Figure 10 As shown, the water-cooling heat dissipation device of the present application is used to dissipate heat for an electronic heating component H, which includes: a water-cooling head 700, a water-cooling radiator 800, a circulating water circuit (component symbols are not marked) and the aforementioned axial flow pump 100, and the electronic heating component H is arranged on a circuit board P.

[0085] The water-cooling head 700 is attached to the electronic heating element H and has two water holes (not labeled). The water-cooling radiator 800 also has two water holes, which can be the water inlet 81 and the water outlet 82. The water-cooling radiator 800 can also be equipped with a cooling fan F. A circulating water circuit surrounds the water-cooling head 700 and the water-cooling radiator 800. The axial-flow pump 100 is connected in series to the circulating water circuit.

[0086] Specifically, the circulating water circuit comprises two first water pipes W1a and W1b, and a second water pipe W2. One end of each of the first water pipes W1a and W1b is connected to a water hole (not labeled) in the water-cooling head 700 and a water outlet 82 in the water-cooling radiator 800, respectively. The axial-flow pump 100 is connected across the other ends of the first water pipes W1a and W1b with its suction hole 1a and discharge hole 1b. The second water pipe W2 is connected at both ends to another water hole in the water-cooling head 700 and the water inlet 81 in the water-cooling radiator 800, respectively.

[0087] In this way, the heat from the electronic heating component H is first transferred to the water in the water cooling head 700, and then the axial flow pump 100 is used to pump the hot water to the water cooling radiator 800 for heat exchange. The water cooled by the heat exchange is then pumped back to the water cooling head 700, thus completing the water cooling heat dissipation.

[0088] In addition, it should be noted that one end of the plurality of blades 22 can be further connected to the socket column 2111 (not shown in the figure), or as shown in FIG. Figure 3 、 Figure 6 and Figure 8 As shown, only a portion of them is connected to the socket column 2111. Specifically, one end of a portion of the aforementioned multiple blades 22 is connected to the socket column 2111 to become a long blade 22, and one end of another portion of the multiple blades 22 is not connected to the socket column 2111 to become a short blade 22. Each short blade 22 is located between two long blades 22 to form a channel opening 26 between the two long blades 22 for discharging water from the diverter channel 25. Each channel opening 26 is connected to the aforementioned diverter channel 25, and the channel opening 26 passes through the end face of the aforementioned hub 21. In this way, since the channel opening 26 has become larger because the short blades 22 are not connected to the socket column 2111, the water output from the impeller 2 in a spiral shape can be increased.

[0089] In summary, the axial flow pump and the water-cooling heat sink with the axial flow pump of the present application can indeed achieve the expected purpose and effect, and can solve the shortcomings of the prior art, so a patent application is filed.

[0090] The above description is only a preferred embodiment of the present application and does not limit the patent scope of the present application. All equivalent structural changes made by using the contents of the present application specification and drawings are also included in the scope of the rights of the present application and are hereby stated.
