Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If water cooling method uses a small part of circulating water to impact the motor through an interstice between the impeller and volute, then the structure is simple, but the heat exchange area is small and heat dissipation is insufficient during high-power operation
Solution Approach 1:
The motor chamber is divided into multiple cooling zones through the annular partition, creating separate flow channels that increase the heat exchange area. The partition plate with through holes segments the water flow path, allowing water to cool different portions of the motor systematically rather than relying on a single impact point.
Solution Approach 2:
The cooling approach transitions from a single-point impact cooling method to a multi-dimensional flow channel system. Water flows through multiple paths including the annular partition channel and return pipe channel, utilizing three-dimensional space within the motor chamber to maximize heat exchange surface area.
2Device complexity
If circulating water cannot flow out in time and be supplemented with new circulating water, then the water circulation system is simple, but heat cannot be dissipated in time during high-power operation
Solution Approach 1:
The return pipe establishes a continuous water circulation pathway that constantly replenishes cool water to the motor chamber and continuously removes heated water. This ensures uninterrupted heat dissipation during high-power operation, maintaining effective cooling throughout the operating cycle.
Solution Approach 2:
The return pipe acts as an intermediary component that facilitates the exchange between the motor chamber and the water intake container. It mediates the removal of heated water and the introduction of fresh cooling water, ensuring timely heat dissipation without complicating the overall system architecture.
3Volume of stationary object
If water cooling channel area is small, then the device structure is compact, but the heat exchange efficiency is insufficient
Solution Approach 1:
The annular partition and return pipe are nested within the motor chamber, utilizing the existing space efficiently. The cooling flow channels are formed by nesting the annular partition between the motor and the motor chamber wall, maximizing heat exchange area without increasing the overall motor chamber volume.

Function Achieved in This Case
The design enhances heat dissipation performance, reduces noise, and ensures reliable operation by maintaining a stable cooling water circulation, preventing motor failure and improving energy efficiency.
Implementation Method 1
a high pressure chamber is formed between the impeller and the partition plate under the action of the rotation of the impeller, and the swimming pool water flows to the motor chamber through the through holes of the partition plate under the action of high pressure
Implementation Method 2
the swimming pool water flows into the flow channel formed by the outer wall of the main body of the motor and the annular partition through the through holes, flushing the outer wall of the main body of the motor to achieve cooling

AI summary
The present disclosure relates to a water pump for a swimming pool, which achieves water cooling by constructing water circulating flow channels inside the water pump for the swimming pool. Due to the arrangement of a low pressure chamber and a high pressure chamber which are formed between a water intake container and a pump chamber, in combination with the water circulating flow channels formed by through holes of a partition plate, an annular partition, a motor casing, an inner wall of a motor chamber, and a first return pipe, a part of swimming pool water entering the water pump is enabled to flow from the water intake container into a pump body under different water pressure differences and the action of an impeller so as to directly flush and cool an outer wall of a motor; and the water can flow back to the water intake container.
