Heat Exchanger Intermediate Sheet Mounting for HVAC Stability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing HVAC systems face issues with heat exchangers being inadequately mounted within the housing, leading to susceptibility to movement, deformation, and unintended contact with other components during transportation and operation, which results in wear and reduced efficiency.
Innovation Solution
The implementation of a heat exchanger design that includes a plurality of intermediate sheets along its length, in addition to end sheets, which are secured to the housing at multiple locations, providing additional mounting points to stabilize the heat exchanger and prevent unwanted movement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If heat exchanger is mounted with only end sheets, then device complexity is reduced, but reliability deteriorates due to susceptibility to shifting and deformation
Solution Approach 1:
The mounting structure is segmented into multiple intermediate sheets distributed along the length of the heat exchanger, in addition to end sheets. This segmentation provides multiple discrete mounting points that independently secure different sections of the heat exchanger, improving overall stability without requiring a monolithic complex structure.
Solution Approach 2:
The mounting system transitions from securing only at the ends (1D point mounting) to distributing mounting points along the entire length (1D linear distribution), adding a dimensional aspect to the mounting strategy. This distributes mechanical stresses and prevents deformation along the longitudinal axis.
2Stability of the object's composition
If heat exchanger is secured at multiple locations, then stability improves, but manufacturing complexity increases
Solution Approach 1:
The heat exchanger is divided into multiple sections along its length, with intermediate sheets positioned at regular intervals. Each section can be independently mounted to the housing, allowing for modular assembly that simplifies manufacturing and installation while maintaining overall stability.
Solution Approach 2:
The mounting system uses standardized intermediate sheets with consistent spacing and attachment mechanisms, transforming the mounting process into a repeatable parameter-based operation. This standardization simplifies manufacturing procedures and reduces installation complexity despite the increased number of mounting points.
3Reliability
If intermediate sheets are added along the heat exchanger, then heat exchanger stability improves, but device complexity increases
Solution Approach 1:
The intermediate sheets are designed as universal mounting components that can be applied at multiple locations along the heat exchanger with identical attachment mechanisms. This multi-functionality reduces the need for location-specific custom parts, simplifying the overall assembly complexity while improving mounting security.
Solution Approach 2:
The same intermediate sheet design is replicated at multiple positions along the heat exchanger length. This copying approach ensures consistent mounting quality across all positions while reducing design complexity, as only one unique sheet design needs to be developed and manufactured in volume.
