Work Machine Lubricating Oil Cooling via Working Fluid Heat Exchange
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing engine oil cooling systems require a large amount of hot engine cooling water to quickly cool lubricating oil, which is inefficient.
Innovation Solution
A work machine configuration where at least a part of the lubricating oil channel and working fluid channel are arranged to facilitate heat exchange between the lubricating oil and the working fluid, allowing for efficient cooling using a new heat medium supplied to a heat exchange unit.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If engine cooling water is used as the heat medium of the oil cooler to quickly cool the lubricating oil, then the cooling speed is improved, but a large amount of cooling water is required and the system becomes complex
Solution Approach 1:
The working fluid channel serves dual purposes: it supplies working fluid to the work unit and simultaneously functions as a heat exchange channel for cooling lubricating oil. This eliminates the need for a separate cooling water system while achieving efficient cooling.
Solution Approach 2:
The patent merges the working fluid channel and lubricating oil cooling function into a single integrated system. The working fluid channel is configured to enable heat exchange with the lubricating oil channel, combining two functions into one structural element.
2Temperature
If a separate oil cooler system is added to cool the lubricating oil, then the cooling capability is improved, but the device complexity increases
Solution Approach 1:
The working fluid channel performs multiple functions: supplying working fluid to the work unit and serving as a heat exchange channel for lubricating oil cooling. This eliminates the need for a separate oil cooler device.
Solution Approach 2:
The patent combines the working fluid channel and lubricating oil cooling function into an integrated system, where the working fluid channel structure itself enables heat exchange with the lubricating oil channel.
3Power
If engine cooling water is used for heat exchange, then the heat exchange capability is improved, but the system requires additional components and space
Solution Approach 1:
The working fluid channel and lubricating oil cooling function are merged into a single integrated system, eliminating the need for separate cooling water channels and associated components.
Solution Approach 2:
The working fluid channel serves dual purposes as both a working fluid supply channel and a heat exchange channel for lubricating oil cooling, maximizing the utility of existing system components.
