Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing cooling jackets, composed of two members with gaps between fins and covers, reduce coolant flow rates and cooling efficiency due to gaps and the need for bonding agents that can leak and clog the system.
Innovation Solution
A single-member cooling jacket design with integrated pipe portions and a main portion that defines a flow path, eliminating gaps and the need for bonding agents, ensuring uniform coolant flow and improved heat transfer.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a cooling jacket is made of two members (main portion and cover), then the structure can be assembled, but gaps are generated between fins and cover which reduces coolant flow rate and cooling efficiency
Solution Approach 1:
The patent merges the main portion and cover into a single integrated cooling jacket structure. The main portion includes integrally formed fins and a cover portion that defines the flow path, eliminating the need for separate assembly. This integration removes gaps between components, ensuring uniform coolant flow and maintaining high cooling efficiency while preserving ease of manufacture through single-piece construction.
2Strength
If bonding agents are used to attach cover to fins, then the two members can be joined, but bonding agents can leak and clog the cooling system
Solution Approach 1:
The patent eliminates the need for bonding agents by integrating the cover and fins into a single piece. The cover portion is formed as an integral part of the main portion, creating a seamless structure where coolant flows uniformly through the defined flow path without risk of bonding agent leakage or clogging, while maintaining structural integrity.
3Device complexity
If gaps exist between fins and cover, then two-member assembly is possible, but coolant flow rate decreases and cooling efficiency deteriorates
Solution Approach 1:
The patent integrates the cover and fins into a single cooling jacket where the cover portion is formed as an integral part of the main portion. This merging eliminates gaps between components, ensuring uniform coolant flow distribution and maximizing cooling performance, while the single-piece construction simplifies the device structure rather than complicating it.
