[0017] 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.

[0018] like Figure 1 , Figure 2 , Figure 3 As shown, this cooling pipe pump includes a pump body 1, an inlet pipe 2 and an outlet pipe 3 located on both sides of the pump body 1, a motor compartment 4, a motor 5 located inside the motor compartment 4, a motor shaft 6 and an impeller 7. An oil tank 8 is provided between the motor compartment 4 and the pump body 1 and is connected to both of them. The motor shaft 6 passes through the upper and lower ends of the oil tank 8 and is connected to the impeller 7 inside the pump body 1. An oil conveying fan blade 9 is provided on the motor shaft 6 located inside the oil tank 8.

[0019] An oil outlet 10 and an oil return 11 are provided above the oil tank 8. An oil outlet pipe 12 is provided on the oil outlet 10. The oil outlet pipe 12 extends upward along the side of the motor 5 to the top of the motor 5. Several arc-shaped pipes 13 are provided on the oil outlet pipe 12. The arc-shaped pipes 13 are all connected to the oil outlet pipe 12 and are symmetrically arranged along both sides of the oil outlet pipe 12. An oil return pipe 14 is provided on the other side of the motor 5, symmetrical to the position of the oil outlet pipe 12. The arc-shaped pipes 13 are all connected to the oil return pipe 14. The oil return pipe extends downward and passes through the oil tank 8 inside the oil return hole 11.

[0020] Several through holes 15 are provided below the oil tank 8. A heat-conducting rod 16 is installed in the through hole 15, and the two ends of the heat-conducting rod 16 are located in the oil tank 8 and the main body, respectively. A heat-conducting part 17 is provided at both ends of the heat-conducting rod 16. A sealing element 18 for sealing is provided between the heat-conducting rod 16 and the through hole 15. The upper and lower ends of the sealing element 18 are provided with limiting parts 19 that respectively fit against the bottom of the oil tank 8 and the upper part of the pump body 1.

[0021] Before use, cool oil is injected into the oil tank 8. When the motor 5 starts, the motor 5 drives the motor shaft 6 to rotate, and at the same time drives the oil conveying fan blade 9 to rotate, so that the cool oil flows from the oil outlet pipe 12, through the arc pipe 13, and finally returns to the oil tank 8 through the oil return pipe 14, realizing circulation and continuously cooling the motor 5.

[0022] Meanwhile, during the operation of this heat dissipation pipeline pump, there will be a continuous alternation of liquid between the inlet pipe 2 and the outlet pipe 3. When the cooling oil absorbs heat, the heat is reduced by the flushing of the water through the heat conduction part 17, thus achieving circulation.

[0023] To elaborate further, an oil injection pipe 20 is provided on one side of the oil tank 8, and a sealing plug 21 is provided on the oil injection pipe 20.

[0024] To elaborate further, a bearing 22 for sealing is provided at the connection between the oil tank 8 and the motor shaft 6, and the motor shaft 6 cooperates with the bearing 22.

[0025] To elaborate further, both the oil outlet pipe and the oil return pipe are interference-fitted to the oil outlet hole 10 and the oil return hole 11, respectively, and are connected by welding.

[0026] To elaborate further, the arc-shaped tubes 13 are all located outside the motor 5.

[0027] To elaborate further, the return oil pipe and several heat-conducting rods 16 are spaced apart from the oil pumping fan blades 9 to prevent interference with the rotation of the oil pumping fan blades 9.

[0028] To elaborate further, the direction of the oil pump blade 9 is the direction that generates an upward thrust on the cooling oil.

[0029] To elaborate further, the heat-conducting part 17 is made of metal materials with good thermal conductivity, such as copper.

[0030] The specific embodiments described herein are merely illustrative examples illustrating the spirit of this utility model. Those skilled in the art to which this utility model pertains may make various modifications or additions to the described specific embodiments or use similar methods to substitute them, without departing from the spirit of this utility model or exceeding the scope defined by the appended claims.

[0031] Although this document frequently uses terms such as pump body 1, inlet pipe 2, outlet pipe 3, motor compartment 4, motor 5, motor shaft 6, impeller 7, oil tank 8, oil conveying fan blade 9, oil outlet hole 10, oil return hole 11, oil outlet pipe 12, arc-shaped pipe 13, oil return pipe 14, through hole 15, heat-conducting rod 16, heat-conducting part 17, seal 18, limiting part 19, oil injection pipe 20, sealing plug 21, and bearing 22, the possibility of using other terms is not excluded. The use of these terms is merely for the convenience of describing and explaining the essence of this utility model; interpreting them as any additional limitation would contradict the spirit of this utility model.
