Solution Overview
Problem
The closed backwater structure in spot-cooling devices for aluminum wheel casting leads to backpressure issues and unstable water flows, necessitating costly supercharging equipment to improve cooling efficiency.
Innovation Solution
An open-type backwater side-mold water spot-cooling device with a groove-like structure, featuring a water inlet main pipe, a water pipe, and a water inlet branch pipe, which reduces backpressure by allowing free flow of backwater through an impounding reservoir and backwater port, eliminating the need for supercharging equipment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If a closed backwater structure is used in spot-cooling devices, then the device can maintain structural integrity, but backpressure increases causing unstable water flow and reduced cooling efficiency
Solution Approach 1:
The patent extracts the backwater discharge function from the closed internal structure by providing a dedicated backwater port that opens to the external environment. This allows the backwater to be discharged freely without creating backpressure within the closed system, while the main body structure remains intact and structurally sound.
Solution Approach 2:
The water cooling system is segmented into distinct functional zones: the water inlet passage for supplying cooling water, the impounding reservoir for temporary water accumulation, and the backwater port for discharge. This segmentation allows each component to perform its specific function optimally without interfering with others, particularly preventing backpressure from affecting the inlet flow.
2Reliability
If supercharging equipment is added to raise water entry pressure, then water flow stability improves, but investment costs increase
Solution Approach 1:
The system uses the gravity and natural pressure of the water supply to achieve stable flow through proper structural design. The impounding reservoir accumulates water naturally, and the open backwater port allows automatic discharge without requiring external supercharging equipment. The structure serves itself to maintain stable water flow through its geometric design alone.
Solution Approach 2:
The patent designs the water passage and reservoir to utilize natural pressure gradients and gravitational potential energy. By positioning the backwater port at an appropriate height and designing the passage geometry to maintain equipotential flow conditions, the system achieves stable water flow without requiring additional energy input from supercharging equipment.
3Reliability
If multiple sealing elements and joints are used in the water passage, then water tightness improves, but manufacturing complexity and maintenance difficulty increase
Solution Approach 1:
The patent extracts the sealing function from multiple distributed joints and seals by providing a single integrated water passage structure with built-in sealing features. The passage is designed as a unified component with the mold, requiring only minimal sealing at the interface, thereby simplifying manufacturing while maintaining water tightness.
Solution Approach 2:
The water passage structure is merged with the spot-cooling device body and mold as an integrated assembly. By combining the water passage, sealing elements, and mounting structure into a unified design, the patent reduces the number of separate components and interfaces, thereby simplifying manufacturing while ensuring water tightness through the integrated structure.
