Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If coolant flows smoothly through the flow channel, then the cooling system is simple, but the temperature distribution becomes uneven and cooling efficiency decreases
Solution Approach 1:
The invention converts the harmful effect of smooth flow (which causes uneven temperature distribution) into a beneficial effect by intentionally introducing turbulence through protrusions. The protrusions create controlled flow disruption that enhances heat transfer, transforming the problem of smooth flow into a solution that improves cooling efficiency while maintaining temperature uniformity.
Solution Approach 2:
The invention changes the flow regime parameter from laminar/smooth flow to turbulent flow by introducing protrusions in the flow channel. This parameter change increases the heat transfer coefficient and improves temperature distribution uniformity, directly addressing the cooling efficiency problem while maintaining system simplicity.
2Temperature
If protrusions are added to create turbulence, then temperature distribution improves, but device complexity increases
Solution Approach 1:
The invention applies local quality by placing protrusions only in specific locations within the flow channel rather than throughout the entire system. The protrusions are positioned to create turbulence zones where needed to improve temperature distribution, while leaving other areas simple. This localized approach enhances cooling efficiency without significantly increasing overall device complexity.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The staggered protrusions create transverse and longitudinal turbulence, improving temperature uniformity and cooling effectiveness by disrupting smooth coolant flow, thereby optimizing thermal management.
Implementation Method 1
a cooling fluid flowing through the spoiler element is blocked by the first protrusion and the second protrusion respectively, thereby forming a turbulence
Implementation Method 2
Coolant is commonly used to flow through the heat dissipation part of the motor to absorb the heat, and then take the heat away from the motor

AI summary
In a linear motor cooling module provided by the invention, mainly at least one spoiler element is provided in a flow channel, the spoiler element has a first protrusion and a second protrusion that are staggered with each other, each of the protrusions extends toward a center of the flow channel in opposite directions, so that a cooling fluid flowing through the spoiler element is blocked by the first protrusion and the second protrusion respectively, thereby forming a turbulence to improve uneven temperature distribution and poor cooling effect.
