Solution Overview
Problem
Existing heat exchangers face challenges in improving their performance, particularly in maintaining efficient heat exchange while preventing condensed water from being blown out, especially in air conditioning systems.
Innovation Solution
The proposed solution involves a heat exchanger with a V-shaped or inverted V-shaped configuration, comprising multiple heat exchanger units with specific core segment arrangements and connection segments, which increase the heat exchange area and improve airflow resistance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a conventional heat exchanger shape is used, then the structure is simple, but the heat exchange performance is insufficient and condensed water is easily blown out
Solution Approach 1:
The heat exchanger is divided into multiple core segments (first core segment, second core segment, third core segment) arranged in sequence. Each segment can be independently designed and assembled, allowing optimization of heat exchange surfaces while maintaining structural manageability. This segmentation enables increased heat exchange area without proportionally increasing overall complexity.
Solution Approach 2:
The patent transitions from a conventional single-plane heat exchanger layout to a three-dimensional folded structure. The core segments are arranged in multiple spatial dimensions with connection segments bridging them, creating a compact volumetric configuration that increases heat exchange surface area without proportionally increasing footprint or structural complexity.
2Reliability
If the heat exchange area is increased, then heat exchange performance improves, but the risk of condensed water being blown out increases
Solution Approach 1:
Different core segments are designed with different local characteristics. The first core segment has a specific fin density and tube arrangement optimized for one region, while the second and third core segments have adjusted parameters suited to their locations. This local optimization allows high heat exchange area while controlling condensed water accumulation and blowout risks in specific critical zones.
Solution Approach 2:
The connection segments are designed with curved or angled transitions rather than sharp corners, creating smoother airflow paths that reduce turbulence-induced condensed water ejection. The folded geometry includes rounded transitions between segments, which helps condensate drain properly while maintaining high heat exchange surface area.
