DETAILED DESCRIPTION

[0029] The present invention will be described in further detail below with reference to the accompanying drawings.

[0030] This specific embodiment is merely an explanation of the present invention and is not a limitation of the present invention. After reading this specification, those skilled in the art may make non-creative modifications to the present embodiment as needed, but as long as they are within the scope of the claims of the present invention, they are protected by patent law.

[0031] This embodiment relates to an integrated water pump with a cooling structure. Figure 1-Figure 3, including: a pump body 100, a controller 200, a pump head 300, a first cooling device 400, a second cooling device 500, a first branch pipe 600 and a second branch pipe 700. Among them, a driving device (not shown) is assembled in the pump body 100, and the driving device is used to provide power support to the water pump. The controller 200 is assembled at one end of the pump body 100, specifically arranged at the top of the pump body 100. A control circuit board 210 is arranged in the controller 200 for opening and closing the working state of the water pump. The pump head 300 is assembled at the other end of the pump body 100, specifically arranged on the side of the pump body 100. The pump head 300 is provided with a connection port 310 for inserting the output shaft of the driving device on the side facing the pump body 100. Specifically, the output shaft of the driving device is fixedly equipped with a turbine device (not shown) for sucking liquid into the pump head 300 or discharging liquid out of the pump head 300. The pump head 300 is also provided with a liquid inlet 320 whose opening direction is arranged parallel to the pump body 100, and a liquid outlet 330 whose opening direction is arranged perpendicular to the pump body 100. When the integrated water pump is started to extract liquid, the liquid is sucked into the pump body 100 through the liquid inlet 320 and then discharged from the liquid outlet 330 through the turbine device. The first cooling device 400 is provided near the side of the control circuit board 210 facing the pump head 300 to cool the control circuit board 210 in the controller 200. The first cooling device 400 is provided with an inlet end 410 and an outlet end 420. The second cooling device 500 is provided in the pump body 100 and is located on the outer periphery of the drive device to cool the drive device. The second cooling device 500 is connected to the first cooling device 400, realizing an integrated cooling system that can simultaneously cool the controller 200 and the drive device without increasing energy consumption. One end of the first branch pipe 600 is connected to the liquid outlet 330, and the other end is connected to the inlet 410 of the first cooling device 400. One end of the second branch pipe 700 is connected to the liquid inlet 320, and the other end is connected to the outlet 420 of the first cooling device 400. A portion of the liquid in the liquid outlet 330 flows from the first branch pipe 600 into the first cooling device 400. Because the first cooling device 400 is connected to the second cooling device 500, the liquid then flows into the second cooling device 500. The liquid then flows back into the first cooling device 400 and flows from the second branch pipe 700 into the liquid inlet 320, thereby forming a closed-loop cooling circulation system. The flow rate of this portion of liquid is less than the flow rate of the liquid outlet 330, and the flow rate of this portion of liquid is 3%-8% of the total flow rate of the pump head 300. This eliminates the need for an external cooling water source, does not affect the normal liquid extraction operation of the integrated water pump, and does not increase additional energy consumption. Therefore, when the driving device is started, the liquid enters the cavity of the pump head 300 through the liquid inlet 320 , and under the action of the turbine device, the liquid flows out from the liquid outlet 330 .At the same time, a portion of the liquid flows to the first cooling device 400 through the first branch pipe 600. After being initially cooled in the first cooling device 400, this portion of the liquid continues to pass through the second cooling device 500. The liquid cooled by the second cooling device 500 returns to the first cooling device 400 and re-enters the liquid inlet 320 of the pump head 300 through the second branch pipe 700, thereby forming a closed-loop cooling circulation system, which realizes the simultaneous cooling of the controller 200 and the drive device. Therefore, compared with early water pumps, the cooling system with the controller 200 and the drive device as one body has the advantage of being able to cool down the temperature simultaneously without increasing energy consumption.

[0032] In this embodiment, referring to Figure 4 The first cooling device 400 has a serpentine guide groove, while the second cooling device 500 has an annular guide groove. The serpentine guide groove increases the contact area between the liquid and the surface of the first cooling device 400, achieving better heat dissipation for the control circuit board 210 and helping to distribute heat more evenly, rather than concentrating it in a single point. The annular guide groove allows the liquid to surround the drive device, ensuring that heat can be effectively removed from all directions, achieving better heat dissipation for the drive device and helping to enhance the cooling effect. In other embodiments, the first cooling device 400 and the second cooling device 500 may also adopt cooling grooves of other shapes.

[0033] In this embodiment, referring to Figure 2-Figure 3 The pump body 100 further includes a first housing 110 that is sleeved on the drive device, and a second housing 120 that is sleeved on the first housing 110. The second cooling device 500 is disposed around the outer periphery of the first housing 110. The first housing 110 and the second housing 120 enhance isolation from the external environment and provide installation space for the second cooling device 500. The surrounding arrangement of the second cooling device 500 further improves heat dissipation.

[0034] Furthermore, the controller 200 is provided with a fixing plate 220 for enclosing the first cooling device 400, ensuring that the first cooling device 400 forms a closed cooling path. A first channel 430 for liquid flow is defined between the fixing plate 220 and the first cooling device 400, while a second channel 510 for liquid flow is defined between the second housing 120 and the second cooling device 500. The first channel 430 allows for efficient liquid flow, effectively cooling the control circuit board 210. The second channel 510 also facilitates liquid flow, effectively absorbing heat from the surrounding area of the drive device, thereby achieving comprehensive cooling.

[0035] In this embodiment, referring to Figure 2-Figure 4The first cooling device 400 includes a first connecting pipe 440 and a second connecting pipe 450. One end of the first connecting pipe 440 is connected to the first channel 430, and the other end is connected to one end of the second channel 510, ensuring that the liquid can smoothly enter the second channel 510 after exiting the first channel 430 to continue its cooling cycle. One end of the second connecting pipe 450 is connected to the other end of the second channel 510, and the other end is connected to the outlet port 420, ensuring that the liquid can be discharged smoothly and directly after completing cooling the drive device. The first connecting pipe 440 and the second connecting pipe 450 ensure the effective transmission of liquid.

[0036] In this embodiment, the second housing 120 includes a first connection port 121 for the first connection pipe 440 to pass through, and a second connection port 122 for the second connection pipe 450 to pass through. The first connection port 121 and the second connection port 122 are accurately connected to the corresponding cooling channels, improving sealing performance.

[0037] In this embodiment, referring to Figure 3 The pump body 100 further includes connectors 130 disposed on both sides of the first housing 110 and the second housing 120, which securely connect the two housings together to ensure the overall structural stability of the pump body 100. The connector 130 is connected to the bottom of the controller 200 via a fixing member. Specifically, the upper and lower sides of the connector 130 are flat, making the assembly of the integrated water pump more secure and reliable and improving the stability after placement. At the same time, the overall water pump structure is more compact and smaller in size.

[0038] Furthermore, the connector 130 has a connection port 310 at one end near the pump head 300, and an output port 131 for inserting the output shaft of the drive device into the cavity of the pump head 300. The connection between the connection port 310 and the output port 131 allows the device to maintain a stable position during operation, avoiding wear or other mechanical problems caused by deviation or swinging.

[0039] In this embodiment, referring to Figure 1-Figure 2 A first switch 610 is provided at one end of the first branch pipe 600 connected to the liquid outlet 330. A second switch 710 is provided at one end of the second branch pipe 700 connected to the liquid inlet 320. The first switch 610 and the second switch 710 cooperate with each other to control the flow rate of part of the liquid so that the flow rate accounts for between 3% and 8%. By adjusting the state of the switch, the amount of liquid entering the first cooling device 400 and the second cooling device 500 can be adjusted, thereby adjusting the cooling effect. In other embodiments, the flow rate of part of the liquid can also be controlled by adjusting the thickness of the first branch pipe 600 and the second branch pipe 700.

[0040] In this embodiment, the controller 200 is provided with a control panel 230 and a handle 240 on the side facing away from the pump body 100. The control panel 230 integrates multiple functions, such as automatic start and stop, timing control, and fault alarms, enhancing the intelligence of the device and facilitating user management and maintenance. The handle 240 makes the integrated water pump even easier to carry and move.

[0041] The above is only used to illustrate the technical solution of the present invention and is not intended to limit it. Other modifications or equivalent substitutions made to the technical solution of the present invention by ordinary technicians in this field should be included in the scope of the claims of the present invention as long as they do not depart from the spirit and scope of the technical solution of the present invention.
