Detailed Implementation

[0016] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0017] like Figs. 1-3 As shown, this water pump with cold circulation includes a centrifugal pump body 1 and a motor 2. The centrifugal pump body 1 is provided with an installation cavity 3 for accommodating the motor 2, a first pressurizing cavity 4, a second pressurizing cavity 5, a water flow channel 6, an inlet 7, and an outlet 8. The first pressurizing cavity 4 and the second pressurizing cavity 5 are respectively located on both sides of the installation cavity 3. The motor 2 is provided with a first output shaft 9 and a second output shaft 10. The first output shaft 9 and the second output shaft 10 are both provided with impeller sets 11 through the installation cavity 3. The water flow channel 6 is used to connect the first pressurizing cavity 4 and the second pressurizing cavity 5. The two ends of the installation cavity 3 are provided with through holes 12 for connecting the first pressurizing cavity 4 and the second pressurizing cavity 5.

[0018] To elaborate further, multiple through holes 12 are provided, and in this application, four through holes 12 are provided to accelerate the water cooling circulation between the first pressurized chamber 4, the mounting chamber 3, and the second pressurized chamber 5.

[0019] To elaborate further, the first output shaft 9 and the second output shaft 10 are in opposite directions, a configuration used to reduce the axial force on the first output shaft 9 and the second output shaft 10.
