Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Large compressors' coolers with non-uniform flow of gaseous medium restrict cooling capacity and lead to increased pressure loss and vibration, making them suboptimal in operation.
Innovation Solution
Incorporation of perforated, plate-like flow homogenization elements upstream of the heat exchanger, potentially subdivided into segments of varying porosity, to ensure uniform flow and optimal operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the cooler is designed with large dimensions to handle high compression volumes, then the cooling capacity increases, but non-uniform flow forms within the cooler restricting cooling capacity
Solution Approach 1:
The flow homogenization element is positioned upstream of the heat exchanger to pre-condition the gaseous medium flow before it enters the cooling tubes. This preliminary action redistributes the non-uniform flow pattern into a more uniform distribution, ensuring optimal cooling performance across the entire heat exchanger surface area.
Solution Approach 2:
The flow homogenization element acts as an intermediary component between the compressor outlet and the heat exchanger. It mediates the flow transition by creating a more uniform velocity and pressure distribution, thereby improving the overall heat transfer efficiency without requiring changes to the fundamental cooler geometry.
2Device complexity
If the cooler operates with non-uniform flow, then the housing structure can be simpler, but pressure loss increases and vibration loading increases
Solution Approach 1:
The flow homogenization element utilizes a porous plate structure with multiple perforations that allow the gaseous medium to pass through while redistributing the flow. The porous design creates numerous flow paths that dampen turbulence and promote uniform velocity distribution, reducing pressure losses without requiring complex housing modifications.
3Device complexity
If the cooler operates with non-uniform flow, then the initial design is simpler, but vibration loading of components increases
Solution Approach 1:
The flow homogenization element is installed during the initial design phase to pre-condition the flow before it reaches the heat exchanger tubes. This preliminary flow conditioning eliminates turbulent fluctuations and non-uniform pressure distributions that would otherwise cause vibration and noise in the cooler components.

Implementation Method 1
at least one perforated, plate-like flow homogenization element is positioned upstream of the portion of the heat exchanger on the flow inlet side. By way of the, or each, flow homogenization element, a uniform flow for the gaseous medium to be cooled through the heat exchanger of the cooler can be realized
Implementation Method 2
a heat exchanger for cooling the compressed, gaseous medium is arranged. Such a cooler comprises a plurality of tubes through which coolant flows and about which the gaseous medium to be cooled circulates

AI summary
A cooler for cooling a gaseous medium includes: a housing; a heat exchanger in the housing, the heat exchanger having an inlet portion at a flow inlet side of the heat exchanger, an outlet portion arranged at a flow outlet side of the heat exchanger, and tubes through which a coolant flows and about which gaseous medium to be cooled circulates; at least one inflow, through which the medium to be cooled can be introduced into the housing and fed to the inlet portion of the heat exchanger; at least one drain, through which cooled medium originating from the outlet portion of the heat exchanger can be discharged out of the housing; and at least one perforated plate-like flow homogenization element positioned in the housing at a position upstream of the inlet portion of the heat exchanger, seen in a flow direction of the medium to be cooled.
