Welded Liquid Collector Integration for Leak-Resistant Heat Exchangers
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional refrigeration systems have complex structures with high risks of external leakage and poor seismic performance due to pipeline connections between components, including the condenser and accumulator.
Innovation Solution
An accumulator and heat exchange device where the accumulator is fixed directly to a heat exchange core body by welding, eliminating the need for pipeline connections, thereby reducing external leakage risk and enhancing seismic performance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If pipeline connection mode is used to connect condenser and accumulator, then components can be assembled separately, but the structure becomes complex and installation space increases
Solution Approach 1:
The patent merges the condenser and accumulator into a single integrated heat exchange device. The accumulator housing is directly formed as part of the heat exchanger assembly, eliminating the need for separate pipeline connections. This combining approach simplifies the overall structure while maintaining manufacturing ease, directly resolving the technical contradiction between ease of manufacture and device complexity.
2Ease of manufacture
If pipeline connection mode is used to connect condenser and accumulator, then components can be assembled separately, but installation space becomes large
Solution Approach 1:
The patent integrates the accumulator housing as an inherent part of the heat exchanger assembly, eliminating the need for external pipeline connections and additional mounting space. This merging reduces the overall installation footprint while preserving the ease of assembly through modular heat exchanger units.
3Ease of manufacture
If pipeline connection mode is used to connect condenser and accumulator, then components can be assembled separately, but external leakage risk increases
Solution Approach 1:
The patent eliminates external pipeline connections by integrating the accumulator housing directly into the heat exchanger assembly. This merging removes multiple potential leakage points at connection interfaces, significantly reducing external leakage risk while maintaining the reliability benefits of separate component manufacturing.
4Ease of manufacture
If pipeline connection mode is used to connect condenser and accumulator, then components can be assembled separately, but anti-seismic performance deteriorates
Solution Approach 1:
The patent integrates the accumulator housing as a unified structure with the heat exchanger assembly, creating a rigid, earthquake-resistant unit. This merging eliminates weak connection points that would be vulnerable to seismic forces, significantly improving anti-seismic performance while preserving the manufacturing advantages of modular heat exchanger components.
