Condenser for an air conditioner, in particular for a motor vehicle
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing condensers in vehicle air conditioning systems face challenges in increasing flexibility in coolant line connections without expanding the installation space, often requiring external 'jumper lines' that increase overall space requirements.
Innovation Solution
An insert with a trough-shaped form and inclined end faces is integrated into the collecting tube, featuring an oil separation opening and an overflow opening to internally manage coolant flow and oil separation, allowing for flexible coolant inlet positioning without external attachments and maintaining compact dimensions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If an outer jumper line is used to arrange the inlet and outlet at desired points, then flexibility in coolant line connections is improved, but the installation space is increased
Solution Approach 1:
The insert is placed inside the collecting tube, with the flow canal nested within the tube's interior space. The overflow opening provides access from the flow canal to the tube's interior, effectively creating a nested structure that allows internal flow management without external attachments.
Solution Approach 2:
The insert creates an internal three-dimensional flow path within the collecting tube, using the tube's internal volume to achieve connection flexibility that would otherwise require external spatial extensions.
2Reliability
If the insert has a complex structure to manage flow and separation, then oil separation efficiency is improved, but the manufacturing cost increases
Solution Approach 1:
The insert includes an oil separation opening that allows oil to pass from the flow canal to the tube interior, utilizing the opening as a simple porous-like structure for separation without complex filtering mechanisms.
Solution Approach 2:
The insert is divided into functional segments: the flow canal for coolant flow, the oil separation opening for oil removal, and the overflow opening for flow regulation. This segmentation allows each feature to be optimized independently while maintaining overall simplicity.

Function Achieved in This Case
This solution enhances flexibility in coolant line connections within the same installation space, effectively separating oil from the coolant flow to optimize compressor lubrication and improve condensation efficiency without increasing the condenser's footprint.
Implementation Method 1
an overflow opening, with the other end, by means of an overflow opening, with the inside of the collecting tube
Implementation Method 2
an oil separation opening through which at least a substantial part of the oil which is transported with the gaseous coolant in the condenser is separated immediately
Implementation Method 3
The function of the condenser consists in extracting heat from the gaseous coolant so that it condenses
Implementation Method 4
extracting heat from the gaseous coolant so that it condenses
