Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional air-cooled type condensers in constant-temperature-fluid circulation devices have limited cooling efficiency, necessitating improvements without increasing the size of the refrigeration circuit unit.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If conventional air-cooled type condenser is used, then the device size is compact, but the cooling efficiency of coolant is insufficient
Solution Approach 1:
The condenser is divided into multiple condenser sections (first condenser section, second condenser section, etc.) arranged in series along the coolant flow direction. Each section has its own inflow conduit, outflow conduit, and fin assembly. This segmentation allows the coolant to be cooled progressively through multiple stages, improving overall cooling efficiency without requiring a single large condenser unit.
Solution Approach 2:
The patent introduces a vertical dimension to the condenser design by stacking condenser sections above and below the horizontal plane. The first condenser section is positioned at an upper level while the second condenser section is positioned at a lower level, creating a multi-level structure that increases cooling surface area and efficiency without proportionally increasing the horizontal footprint of the device.
2Loss of energy
If multiple condenser sections are arranged in series, then cooling efficiency is improved, but device complexity increases
Solution Approach 1:
Multiple condenser sections are merged into a single integrated condenser assembly that functions as one unit. The sections share common structural elements and are connected through the coolant flow path, allowing them to operate cooperatively to achieve improved cooling efficiency while maintaining a unified structural form factor.
Solution Approach 2:
Each condenser section is designed with universal components that perform multiple functions: the fins serve as both heat exchange surfaces and structural support, the conduits serve as both coolant channels and mounting structures, and the overall assembly serves as both the cooling device and the structural framework for mounting other components.
3Loss of energy
If fins are mounted between condenser tubes, then heat exchange efficiency is improved, but manufacturing complexity increases
Solution Approach 1:
The fins are nested between the condenser tubes in a compact arrangement where multiple fin layers are positioned between adjacent tubes. This nested configuration maximizes the heat exchange surface area within the limited space between tubes, improving heat transfer efficiency without requiring additional external space or complex assembly procedures.
