Heat Exchanger Mounting via Tank Undercut Integration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Heat exchanger assemblies in vehicles face space constraints and require multiple components for mounting, leading to complex installations and increased costs due to the need for brazing and riveting of additional brackets.
Innovation Solution
A heat exchanger assembly design featuring an undercut in the end caps of the tank, allowing for a single connection piece to be fixed behind the undercut, eliminating the need for separate mounting brackets and simplifying the installation process by reducing the number of components and eliminating the need for brazing and riveting.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple mounting brackets are used to secure the heat exchanger, then the attachment reliability is improved, but the device complexity and number of components increase
Solution Approach 1:
The patent combines multiple separate mounting brackets into a single integrated connection piece that attaches to the heat exchanger tank. This single connection piece incorporates all necessary mounting functions, reducing the total number of components while maintaining secure attachment to the vehicle frame.
Solution Approach 2:
The connection piece is designed as a multi-functional component that simultaneously serves as both a mounting bracket and a structural support element. It integrates the functions of multiple separate brackets into one universal component that can be attached to the tank and secured to the vehicle frame.
2Strength
If additional mounting brackets are used, then the structural strength is improved, but the manufacturing complexity and cost increase due to brazing and riveting
Solution Approach 1:
The connection piece combines multiple bracket functions into a single manufactured component, eliminating the need for separate brazing and riveting operations for each individual bracket. This reduces manufacturing steps and associated costs while maintaining the required structural strength through the integrated design.
Solution Approach 2:
The invention extracts the essential mounting function from multiple complex brackets and concentrates it into a single simplified connection piece. This extracted design removes unnecessary complexity while retaining the core structural support and attachment capabilities needed for heat exchanger mounting.
3Reliability
If multiple separate mounting components are used, then the attachment security is improved, but the installation time and complexity increase
Solution Approach 1:
The single integrated connection piece combines all mounting functions into one component, allowing installers to complete the attachment in a single operation rather than assembling and securing multiple separate brackets. This reduces installation time while maintaining secure attachment through the unified design.
4Volume of moving object
If a compact mounting solution is implemented, then the space utilization is improved, but the structural strength may be compromised
Solution Approach 1:
The integrated connection piece consolidates multiple mounting functions into a single compact component, reducing the overall volume occupied by the mounting assembly. The unified structure maintains structural strength through its integrated design, eliminating the need for multiple separate brackets that would occupy more space.
