Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional heat exchangers in domestic central heating systems face inefficiencies in heat exchange processes due to suboptimal design features, particularly in the shape and arrangement of sieve walls and partitions, which affect water circulation and pressure distribution, leading to reduced heat transfer effectiveness.
Innovation Solution
A heat exchanger design featuring a conical outer jacket with vertically arranged pipe elements, cone-shaped sieve walls, and partitions with specific flare angles and central openings, along with additional openings on the upper partition, enhances water circulation and heat exchange efficiency by optimizing water flow and pressure distribution.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If conventional flat sieve walls and partitions are used in heat exchangers, then the structure is simple and easy to manufacture, but water circulation is suboptimal and heat exchange efficiency is reduced
Solution Approach 1:
The patent applies curvature by replacing flat sieve walls and partitions with conical surfaces. The upper sieve wall, lower sieve wall, and partitions are all shaped as cones with specific flare angles (150°, 130°, and 90-170° respectively). This curvature optimizes water circulation patterns and pressure distribution, significantly increasing heat exchange effectiveness across the entire height of pipe elements, particularly in the upper sieve wall and combustion chamber area.
2Productivity
If conventional cylindrical outer jackets are used, then manufacturing is straightforward, but water flow distribution and pressure acting on partitions is suboptimal
Solution Approach 1:
The outer jacket is designed as a conical structure instead of a conventional cylindrical shape. This conical outer jacket, combined with conical sieve walls and partitions, creates optimized water flow distribution and pressure distribution. The curved conical surfaces guide water flow more effectively, preventing dead zones and ensuring maximum heat transfer efficiency throughout the heat exchanger.
3Productivity
If flat partitions are used without central openings, then the structure is simpler, but dead zones form and heat exchange effectiveness is reduced
Solution Approach 1:
The partitions are designed as conical surfaces with central openings instead of flat solid partitions. The conical shape with specific flare angles (90-170°) and central openings prevents dead zone formation by directing water flow through the partition structure. This design ensures continuous water circulation and maximizes heat exchange effectiveness throughout the entire heat exchanger volume.
