Connector System Cooling Air Discharge Path
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional air compressors face efficiency degradation and potential damage due to the mixing of hot air with moisture from the system exhaust, leading to pressure reversal and damage when the exhaust pressure exceeds the discharge pressure.
Innovation Solution
A connector system is introduced that includes additional cooling flow passages to discharge hot air generated from air compressors, water pumps, or air fans to the outside, separate from the system exhaust, preventing pressure reversal and damage by routing the hot air through a series of connectors and filters.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If hot air from the airfoil bearing cooling passage is transferred to the impeller entrance through the shaft hollow, then the cooling function is achieved, but the compressor efficiency degrades due to mixing with newly introduced air
Solution Approach 1:
The patent extracts the hot air discharge function from the traditional shaft hollow path and creates a separate dedicated cooling air discharge passage. This allows the cooling function to be maintained while preventing the harmful mixing of hot air with fresh intake air at the impeller entrance, thereby resolving the contradiction between cooling effectiveness and compressor efficiency.
2Ease of operation
If the secondary flow passage is connected to the system exhaust, then a discharge path is provided, but pressure reversal causes exhaust to flow back into the compressor causing damage
Solution Approach 1:
The patent segments the air discharge system into separate independent pathways: a dedicated cooling air discharge passage for hot air from the airfoil bearing, and the existing exhaust system for combustion exhaust. This segmentation prevents pressure reversal in the exhaust system from affecting the cooling air flow, and vice versa, thereby maintaining both discharge path availability and compressor safety.
3Reliability
If a separate cooling air discharge passage is created, then pressure reversal is prevented and compressor safety is improved, but the device complexity increases
Solution Approach 1:
The patent merges the cooling air discharge function with the existing connector structure that connects the air compressor to the controller. By integrating the cooling air passage into the connector housing and utilizing the existing cable routing space, the design adds the safety function without creating entirely separate components, thereby minimizing the increase in device complexity.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution effectively transfers hot air to the outside without causing pressure reversal, thereby preventing damage to the compressor and maintaining efficiency by isolating the discharge flow from the system exhaust.
Implementation Method 1
the connector body (110) may include a cooling air discharge passage (113) extending from one end of the connector body (110) to the other end of the connector body (110)... such that the cooling air discharge passage (113) is separated from the space (111) in which the connector terminal (112) is disposed
