Battery Cooling Layout for Easier Heat Exchanger Maintenance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In air-cooled battery units, it is challenging to adjust the temperature quickly to an appropriate range, leading to difficulties in maintenance due to the presence of heat exchangers in water-cooling methods.
Innovation Solution
A work machine configuration where the heat exchanger is positioned on the opposite side of the battery unit from the pipe connection, allowing for easier maintenance by separating the heat exchanger from the battery unit's connection area.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If water-cooling method is employed with heat exchanger, then cooling efficiency is improved, but maintenance accessibility deteriorates
Solution Approach 1:
The patent divides the cooling system into separate functional modules: the battery unit with connection ports, the pipe network, and the heat exchanger. This segmentation allows the heat exchanger to be positioned independently on the opposite side of the battery unit, improving both cooling efficiency and maintenance accessibility without requiring disassembly of integrated components.
2Temperature
If heat exchanger is positioned on battery unit side, then cooling performance is improved, but maintenance difficulty increases
Solution Approach 1:
The patent relocates the heat exchanger from a position adjacent to the battery unit to the opposite side, utilizing spatial dimensionality to resolve the conflict between cooling performance and maintenance ease. The connection ports on the battery unit are positioned to accommodate pipes extending to the heat exchanger location, maintaining effective cooling while providing unobstructed access for maintenance operations.

AI summary
A work machine includes a battery unit, a pipe which is connected to the battery unit and through which a heat exchange medium flows, and a heat exchanger to which the pipe is connected. The heat exchanger is disposed on a side opposite to a side of the battery unit which is connected to the pipe, with respect to the battery unit.
