Heat exchanger fixing structure of air conditioner
Solution Overview
Problem
Existing heat exchanger fixing structures for air conditioners require separate brackets, increasing material costs and operational time, and may lead to vibration and noise due to collisions between overlapping heat exchangers.
Innovation Solution
A heat exchanger fixing structure that connects multiple bent heat exchangers using integral plates with overlapping portions and fastening members, eliminating the need for a separate bracket by aligning and securing the plates through strategically placed convex and concave portions and screw holes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If a separate fixing bracket is used to secure multiple heat exchangers, then the heat exchangers are stably fixed and vibration is reduced, but material cost increases and production time is extended
Solution Approach 1:
The fixing function is merged with the heat exchanger plates themselves. The plates are designed with overlapping portions and integrated fastening structures (convex portions, concave portions, and screw holes) that eliminate the need for separate fixing brackets. This integration maintains stable fixation while reducing component count and production complexity
Solution Approach 2:
The heat exchanger plates serve dual functions: their primary function as heat transfer components and their secondary function as fixing structures. The plates include integrated fastening features that enable them to secure other plates and heat exchanger units, making the structure self-sufficient without requiring additional dedicated fixing components
2Object-affected harmful factors
If a separate fixing bracket is used to prevent collisions between heat exchangers, then vibration and noise are reduced, but device complexity and material cost increase
Solution Approach 1:
The collision prevention and vibration reduction functions are merged into the plate structure itself. The overlapping plate design with integrated fastening features creates a unified structure that eliminates gaps and potential collision points between heat exchanger units, reducing vibration and noise without adding separate bracket components
Solution Approach 2:
The separate fixing bracket component is extracted and removed from the system. Instead of adding a bracket, the fixing and collision prevention functions are achieved through the modified plate structure alone, simplifying the overall device while maintaining effectiveness
3Reliability
If multiple separate components are used for fixing heat exchangers, then reliable fixation is achieved, but the number of parts increases and assembly time is extended
Solution Approach 1:
Multiple fixing components are merged into a single integrated plate structure. The plates incorporate overlapping portions, convex portions, concave portions, and screw holes that work together as a unified fixing system, reducing the number of separate parts and assembly steps while maintaining reliable fixation
Solution Approach 2:
The fixing structures are pre-integrated into the plate design during manufacturing. The convex portions, concave portions, and screw holes are built into the plates before assembly, allowing for rapid installation without requiring separate fixing components to be attached during assembly
