Description

Technical Field

[0001] This utility model belongs to the field of water pump controllers, and specifically relates to a water-cooled controller for pumps and a water pump. Background Technology

[0002] Existing pump controllers typically use fans for cooling, removing heat through airflow. However, fans and heat sinks usually occupy space, making the controller relatively bulky. Air has low heat transfer efficiency; if the air is hot, the amount of heat removed is very limited, easily leading to a cooling bottleneck and large temperature fluctuations. To ensure effective cooling, the fan speed needs to be increased, which often results in higher noise levels in such controllers, requiring improvement. Utility Model Content

[0003] To address the problems of unsatisfactory heat dissipation and high noise in existing air-cooled controllers, this utility model provides a water-cooled controller for pumps. By setting up a cooling pipe connected to a water source, the controller utilizes water flow for heat dissipation, achieving a more ideal heat dissipation effect and effectively reducing noise.

[0004] The technical solution adopted by this utility model is as follows: A water-cooled controller for a pump includes a housing and a top cover that are enclosed by upper and lower parts. A circuit board is accommodated between the housing and the top cover. A partition wall is provided inside the housing. The circuit board is connected to the partition wall from top to bottom. A cooling pipe that can be connected to a water source passes through the housing. The cooling pipe is connected to the partition wall from bottom to top through a connecting assembly. A heating element is provided on the circuit board. The heating element is in close contact with the partition wall, or the heating element is vertically aligned with the cooling pipe, so that the heat generated by the heating element is directly or indirectly transferred to the cooling pipe.

[0005] The heating element on the circuit board is in close contact with the partition wall, which can transfer the heat generated by it to the partition wall. Alternatively, the heating element is positioned vertically with the cooling pipe, which can directly transfer the heat to the cooling pipe. This allows the heating element to quickly transfer the heat to the cooling pipe. The water flow in the cooling pipe can carry away the heat transferred to it, ensuring the heat dissipation effect. Furthermore, no fan is needed, which effectively avoids the impact of wind noise.

[0006] Furthermore, the connecting assembly includes a positioning seat and a connecting piece. The top surface of the positioning seat is tightly abutted against the lower surface of the partition wall, and the connecting piece is an arc-shaped piece that connects to the positioning seat from bottom to top, so that the cooling pipe is clamped by the connecting piece and the bottom surface of the positioning seat. Water pipes are typically cylindrical with smooth outer surfaces. The positioning seat and connecting piece can position the smooth-surfaced cooling pipe, ensuring its stability and secureness. In addition, the positioning seat provides a large contact surface, ensuring efficient heat transfer.

[0007] Furthermore, the partition wall is provided with a clearance hole, and the top surface of the positioning seat covers the clearance hole from bottom to top. The heating element is attached to the top surface of the positioning seat through the clearance hole. The top surface of the positioning seat is flat, which covers the clearance hole and provides a more ideal contact surface. The positioning seat is attached to the lower part of the partition wall, and both contact surfaces are flat, which can ensure structural stability and reliability. The heating element is in direct contact with the positioning seat, the heat transfer path is short, and there is no need for the partition wall as an intermediate medium. The heat transfer efficiency is high, and the heat generated by the heating element can be quickly dissipated to ensure the heat dissipation effect.

[0008] Furthermore, a sealing ring is provided between the partition wall and the positioning seat, and the sealing ring surrounds the outside of the clearance hole. The sealing ring protects the clearance hole, providing dustproof and water-proof effects to prevent the circuit board from contacting water.

[0009] Furthermore, the partition wall protrudes upward to form a downward-facing receiving cavity, and the sealing ring is embedded in the receiving cavity. The receiving cavity restricts the horizontal movement of the sealing ring, ensuring that the sealing ring is compressed by the partition wall and the positioning seat, thus ensuring dustproof and waterproof effects.

[0010] Furthermore, the housing includes a self-closing enclosure panel with two through holes. Each through hole has a clamping pad, which is fitted onto the cooling pipe. The clamping pad serves to clamp and secure both ends of the cooling pipe, while also preventing the cooling pipe from colliding with the enclosure panel and providing a certain degree of cushioning.

[0011] Furthermore, the housing also includes a base plate disposed at the bottom of the enclosure panel, the base plate having a vertical edge connected to the enclosure panel. The vertical edge is connected to the enclosure panel via a connector, and the base plate can be embedded in the bottom of the enclosure panel, with the joint between the base plate and the enclosure edge facing downwards, providing better concealment.

[0012] Furthermore, a pressure sensor is installed through the wall of the cooling pipe, and the pressure sensor is housed within the housing. A wiring hole is provided on the partition wall, through which the connecting wire of the pressure sensor passes and connects to the circuit board. Existing water pump pressure sensors are typically mounted on the pump body; however, external sensors occupy space, affecting the rational layout of various components and preventing the entire water pump from achieving a compact fit. Therefore, placing the pressure sensor within the housing effectively solves the problems of unreasonable layout and non-compact structure caused by external pressure sensors.

[0013] Furthermore, a one-way valve is provided at one end of the cooling pipe.

[0014] A water pump includes a pump body and a controller, wherein the controller is a water-cooled controller as described above, and the pump body has a water outlet connected to a cooling pipe of the controller.

[0015] The beneficial effects of this utility model are as follows: This application is a water-cooled controller and water pump for a pump. The heat-generating element on the circuit board can be quickly transferred to the cooling pipe, and the heat is carried away by the water flow in the cooling pipe, ensuring the heat dissipation effect. Moreover, no fan is used, which effectively avoids the influence of wind noise. Attached Figure Description

Detailed Implementation

[0024] The technical solutions of the embodiments of this utility model will be explained and described below with reference to the accompanying drawings. However, the following embodiments are only preferred embodiments of this utility model and not all of them. Other embodiments obtained by those skilled in the art based on the embodiments in the implementation methods without creative effort are all within the protection scope of this utility model.

[0025] Example 1

[0026] The pump in this embodiment uses a water-cooled controller, such as... Figures 1 to 7As shown, the device includes a housing 1 and a top cover 2 that enclose the space between the housing 1 and the top cover 2. A circuit board 4 is housed between the housing 1 and the top cover 2. The housing 1 has a recessed partition wall 11. The circuit board 4 is connected to the partition wall 11 from top to bottom. A cooling pipe 5 that can connect to a water source passes through the housing 1. The cooling pipe 5 is connected to the partition wall 11 from bottom to top via a connecting assembly 3. A heating element 41 is provided on the circuit board 4. The heating element 41 corresponds vertically to the cooling pipe 5. The connecting assembly 3 includes a positioning seat 31 and a connecting piece 32. The top surface of the positioning seat 31 is in close contact with the lower surface of the partition wall 11. The connecting piece 32 is an arc-shaped piece that is connected to the positioning seat 31 from bottom to top, so that the cooling pipe 5 is clamped by the bottom surface of the connecting piece 32 and the positioning seat 31.

[0027] The recessed partition wall 11 can lower the center of gravity of the circuit board 4, ensuring structural stability and reliability. The heating element 41 is positioned vertically with the cooling pipe 5, directly transferring heat to the cooling pipe 5. This facilitates the rapid transfer of heat from the heating element 41 to the cooling pipe 5. The water flow inside the cooling pipe 5 can carry away the heat transferred to it, ensuring heat dissipation. Furthermore, no fan is needed, effectively avoiding the impact of wind noise.

[0028] Cooling pipe 5 is typically cylindrical with a smooth outer surface, making direct positioning difficult. If cooling pipe 5 directly contacts partition wall 11, it's equivalent to a curved surface contacting a flat surface, but the contact area between the curved and flat surfaces is limited, failing to guarantee heat transfer efficiency. The top surface of positioning seat 31 is flat, and the bottom of positioning seat 31 is adapted to the shape of the outer wall of cooling pipe 5, transforming the curved surface of cooling pipe 5 into a flat surface. This ensures both the contact area between positioning seat 31 and cooling pipe 5 and a tight fit between positioning seat 31 and partition wall 11, resulting in a large contact area. Therefore, setting up positioning seat 31 and connecting piece 32 can position the smooth-surfaced cooling pipe 5, ensuring the stability and firmness of the water pipe, and also guaranteeing heat transfer efficiency.

[0029] like Figure 4 , Figure 5 and Figure 6 As shown, the partition wall 11 is provided with a clearance hole 12. The top surface of the positioning seat 31 covers the clearance hole 12 from bottom to top. The heating element 41 is attached to the top surface of the positioning seat 31 through the clearance hole 12. The top surface of the positioning seat 31 is flat, which covers the clearance hole 12 and provides a relatively ideal contact surface. The positioning seat 31 is attached to the lower part of the partition wall 11. Both of the contact surfaces are flat, which can ensure structural stability and reliability. The heating element 41 is in direct contact with the positioning seat 31, the heat transfer path is short, and there is no need for the partition wall 11 as an intermediate medium. The heat transfer efficiency is high, and the heat generated by the heating element 41 can be quickly discharged to ensure the heat dissipation effect.

[0030] A sealing ring 6 is provided between the partition wall 11 and the positioning seat 31, and the sealing ring 6 surrounds the outside of the clearance hole 12. The sealing ring 6 protects the clearance hole 12, and plays a role in preventing dust and water, so as to prevent the circuit board 4 from coming into contact with water and causing a short circuit.

[0031] like Figure 6 As shown, the partition wall 11 protrudes upward to form a downward-facing receiving cavity 112, and the sealing ring 6 is embedded in the receiving cavity 112. The receiving cavity 112 restricts the horizontal movement of the sealing ring 6, so that the sealing ring 6 is squeezed and clamped by the partition wall 11 and the positioning seat 31 from top to bottom. The sealing ring 6, which has a certain elasticity, fills the gap between the partition wall 11 and the positioning seat 31, effectively ensuring the dustproof and waterproof effect.

[0032] like Figure 4 As shown, the housing 1 includes a self-enclosing panel 13. The panel 13 has two through holes 14, which are arched. Each through hole 14 has a clamping pad 7, which is made of rubber or plastic and has a central perforation. The cooling pipe 5 passes through the central perforation so that the clamping pad 7 can be fitted onto the cooling pipe 5. The clamping pad 7 serves a clamping function, ensuring that both ends of the cooling pipe 5 are fixed, preventing the cooling pipe 5 from colliding with the surrounding edge, and also providing a certain degree of cushioning.

[0033] like Figure 4 As shown, the housing 1 also includes a base plate 15 disposed at the bottom of the surrounding plate 13. The base plate 15 has a vertical edge 151, which is connected to the surrounding plate 13. The bottom of the clamping pad 7 is flat so that the base plate 15 can support it, thereby limiting the clamping pad 7. The vertical edge 151 and the surrounding plate 13 are provided with corresponding connecting holes so that the two can be connected by connectors. In this way, the base plate 15 can be embedded in the bottom of the surrounding plate 13. The joint between the base plate 15 and the surrounding edge faces downward, which provides a better shielding effect and prevents dust accumulation.

[0034] like Figure 3 and Figure 7 As shown, a pressure sensor 8 is installed through the wall of the cooling pipe 5. The pressure sensor 8 is housed within the housing 1. A wire through hole 111 is provided on the partition wall 11, through which the connecting wire of the pressure sensor 8 passes and connects to the circuit board 4. In existing water pumps, the pressure sensor 8 is usually mounted on the pump body. However, external sensors occupy space, affecting the rational layout of various components and preventing the entire water pump from achieving a compact fit. Therefore, placing the pressure sensor 8 within the housing 1 effectively solves the problems of unreasonable layout and non-compact structure caused by external pressure sensors 8.

[0035] One end of the cooling pipe 5 is equipped with a one-way valve to ensure that the water flows in one direction and avoids backflow.

[0036] Example 2

[0037] The difference between this embodiment and embodiment 1 is that the heating element 41 on the circuit board 4 is in close contact with the partition wall 11, and the heat generated by the heating element 41 is transferred to the partition wall 11 and then to the positioning seat 31.

[0038] Example 3

[0039] A water pump includes a pump body and a controller. The controller is a water-cooled controller as described in Embodiment 1. The pump body has a water outlet, which is connected to a cooling pipe 5 of the controller. The water accelerated by the pump body flows directly into the cooling pipe 5, which not only ensures the cooling effect but also makes the overall layout of the water pump more reasonable.

[0040] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Those skilled in the art should understand that this utility model includes, but is not limited to, the content described in the accompanying drawings and the specific embodiments above. Any modifications that do not depart from the functional and structural principles of this utility model will be included within the scope of the claims.
