Split-Type Heat Exchanger Partition for Refrigerant Pipe Mounting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing heat exchangers face challenges in mounting refrigerant pipes reliably, leading to potential leakage and reduced service life due to flexibility issues and vibration, which affect the overall performance and reliability of the device.
Innovation Solution
A split-type partition for the heat exchanger is introduced, comprising a first and second partition portion with an engaging structure, including an engaging groove and protrusion, that clamps the refrigerant pipe, allowing for improved assembly efficiency and reduced leakage risks by controlling the hole size and facilitating proper positioning during assembly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If the mounting hole size is reduced to improve positioning precision, then manufacturing precision is improved, but the refrigerant pipe cannot be inserted due to insufficient gap
Solution Approach 1:
The partition is divided into a first partition portion and a second partition portion that can be assembled separately. The first partition portion with the mounting hole is assembled first, allowing the refrigerant pipe to be inserted easily, and then the second partition portion is added to complete the sealing, thus avoiding the need for a precisely controlled small mounting hole throughout the entire assembly process
Solution Approach 2:
The first partition portion is assembled with the mounting hole before the refrigerant pipe insertion, preparing the mounting structure in advance. This preliminary assembly allows for easier pipe insertion while maintaining positioning precision through the subsequent engagement of the second partition portion
2Adaptability or versatility
If the refrigerant pipe is made flexible to improve adaptability, then adaptability is improved, but mounting reliability deteriorates due to vibration and leakage
Solution Approach 1:
By dividing the partition into two portions that clamp the refrigerant pipe from different directions, the structure provides both flexibility accommodation and reliable fixation. The first partition portion allows for insertion while the second portion provides additional support to prevent vibration-induced leakage
Solution Approach 2:
The first and second partition portions work together as a unified clamping structure. The combination of both portions creates a secure mounting system that maintains reliability while accommodating the flexibility of the refrigerant pipe through their cooperative engagement

AI summary
A baffle (4) and a heat exchanger with the baffle (4) are provided. The baffle (4) is disposed inside a header pipe (2) of the heat exchanger, and divides the header pipe (2) into two sections along the axial direction. The baffle (4) supports a refrigerant duct (3) which is set inside the header pipe (2) along the axial direction. The baffle (4) is a split type, and includes a first baffle member (41) and a second baffle member (42) connected together via an engagement structure. The installation efficiency of the baffle (4) and the installation quality of the refrigerant duct (3) are enhanced, and the reliability of the heat exchanger is also improved.
