Heat Exchanger Isolator With Elastic Body for Vibration Isolation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Direct contact between heat exchangers and mounting fasteners in vehicles leads to the transfer of vibrations and loads, risking radiator failure.
Innovation Solution
An isolator with an elastic body and non-elastic core is used to mount the heat exchanger, allowing a threaded fastener to connect through the isolator, isolating the heat exchanger from the vehicle frame.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a threaded bolt directly connects the radiator to the vehicle frame, then the mounting structure is simple and robust, but vibrations and loads are transferred directly to the radiator causing potential failure
Solution Approach 1:
The patent introduces an isolator as an intermediary component between the radiator and vehicle frame. This isolator comprises a soft elastomeric material body with a through-hole, allowing the threaded bolt to pass through while preventing direct contact between the radiator and frame. The elastomeric material absorbs and isolates vibrations, eliminating the harmful vibration transfer while maintaining secure mounting.
Solution Approach 2:
The isolator utilizes composite material construction with an elastomeric material body that combines damping properties with structural integrity. The elastomeric material provides vibration isolation while the overall isolator structure maintains mechanical strength to support the radiator mounting, creating a composite solution that addresses both durability and vibration concerns.
2Object-affected harmful factors
If an isolator is introduced between the radiator and fastener, then vibration transfer is reduced, but the mounting structure becomes more complex
Solution Approach 1:
The isolator merges multiple functions into a single component: it provides vibration isolation through its elastomeric material, serves as a mounting interface for the threaded bolt via the through-hole, and maintains structural support for the radiator. This consolidation reduces the overall mounting structure complexity compared to using separate isolation elements and mounting hardware.
Solution Approach 2:
The isolator employs an elastomeric material body that functions as a flexible element to absorb and dampen vibrations. The flexible nature of the elastomeric material allows it to deform under vibration loads while maintaining the mounting connection, providing effective vibration isolation without requiring complex rigid structures.
