Condenser Outlet Channel Positioning for Leakage Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing condensers in heat transfer systems, particularly in heat pumps, suffer from excessive heating of the fluid as it flows between the grouping area and the outlet opening, leading to increased leakage risks due to higher heat transfer from the fluid tank.
Innovation Solution
The condenser design positions the second end of the outlet channel closer to the housing bottom compared to traditional designs, reducing the heat area where the fluid can be heated, thereby minimizing fluid heating and enhancing subcooling.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the outlet channel is positioned with its second end closer to the housing bottom, then fluid heating is reduced and subcooling is enhanced, but the heat transfer area is reduced
Solution Approach 1:
The outlet channel is positioned in a specific location (second end closer to housing bottom) to create different thermal conditions in different regions of the condenser. This local positioning reduces fluid heating in the outlet region while maintaining overall heat transfer functionality through the channel system's design with splitting and grouping portions.
2Temperature
If the second end of the outlet channel is positioned nearer to the housing bottom, then fluid heating is minimized, but the distance for fluid flow increases
Solution Approach 1:
The outlet channel is configured to extend in multiple directions rather than a simple linear path. The channel system includes splitting portions and grouping portions that create a multi-dimensional flow path, allowing the second end to be positioned nearer to the housing bottom while maintaining adequate flow length through spatial optimization.

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This design improvement reduces the heat transfer from the fluid tank to the fluid, leading to a decrease in fluid heating, increased expansion valve capacity, reduced gas creation in the outlet channel, and lower leakage risks, ultimately enhancing the overall efficiency of the heat transfer system.
Implementation Method 1
The heat transfer from the fluid tank to the fluid flowing in the condenser results from that in the fluid tank warmer fluid is arranged in an upper area of the fluid tank due to density differences
Implementation Method 2
The sustainability against leakage is influenced by the subcooling of the fluid in the condenser

AI summary
The invention relates to a condenser comprising a housing having an inlet opening for inputting fluid into the condenser and an outlet opening for outputting the fluid out of the condenser and a channel system for fluidically connecting the inlet opening and the outlet opening, wherein the channel system is arranged within the housing and comprises a splitting portion in which the inputted fluid is split to a plurality of channels and a grouping portion in which the plurality of channels is united to an outlet channel, wherein a first end of the outlet channel ends in the outlet opening and a second end of the outlet channel ends in the grouping portion. The condenser is characterized in that a distance between the second end of the outlet channel and a housing bottom in a vertical direction is between 0% to 80% of a distance between the housing bottom and an upper housing side in a vertical direction.
