Adjustable Refrigerant Distribution Pipe Design for Flow Rate Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing refrigerant distribution devices in heat exchangers have a fixed refrigerant flow rate, making it difficult and inefficient to adjust refrigerant distribution schemes, requiring device replacement to change flow rates.
Innovation Solution
A refrigerant distribution device with an inner and outer distribution pipe system, where the inner distribution pipe has multiple hole units with adjustable inner distribution holes that can align with outer distribution holes, allowing for flexible adjustment of refrigerant flow without replacing the device.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a fixed refrigerant distribution device is used, then the device structure is simple, but the refrigerant flow rate cannot be adjusted without replacing the device
Solution Approach 1:
The patent implements adjustability by making the inner distribution pipe movable relative to the outer distribution pipe. The inner pipe can be positioned at different locations within the outer pipe, allowing different numbers of inner distribution holes to align with outer distribution holes, thereby dynamically adjusting the refrigerant flow rate without replacing the entire device.
Solution Approach 2:
The distribution device is divided into two independent parts: an outer distribution pipe with outer distribution holes and an inner distribution pipe with inner distribution holes. This segmentation allows the inner pipe to be independently positioned and adjusted within the outer pipe, enabling flexible control over refrigerant distribution while maintaining a relatively simple overall structure.
2Adaptability or versatility
If the refrigerant distribution device is replaced to adjust flow rate, then the refrigerant flow can be changed, but the working efficiency is greatly affected
Solution Approach 1:
The adjustable inner distribution pipe eliminates the need for device replacement. Users can simply reposition the inner pipe within the outer pipe to change the alignment between holes, thereby adjusting the refrigerant flow rate quickly and conveniently without time-consuming replacement operations.
3Adaptability or versatility
If multiple distribution schemes are needed, then the refrigerant distribution flexibility is improved, but the device complexity increases
Solution Approach 1:
The movable inner distribution pipe enables multiple distribution schemes by allowing different positioning configurations. By adjusting the inner pipe's position, different numbers and patterns of hole alignments are achieved, providing various distribution schemes while maintaining a simple two-pipe structure without adding complex mechanisms.
