Shroud Partition Layout for Compact Working Machine Cooling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing working machines have a significant space left around the shroud, which is inefficient and can be optimized for better space utilization.
Innovation Solution
Incorporating a partition plate that includes an opening for the shroud to extend through, with mounting portions for attachment, and a support frame that integrates with a base plate and hood to define the prime mover room, allowing the shroud and cooling devices to be attached as a unified unit, and utilizing sealing members to seal gaps.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If a shroud is provided to guide cooling air flow, then cooling performance is improved, but significant space is left around the shroud which reduces space utilization efficiency
Solution Approach 1:
The partition plate is merged with the shroud by providing an opening in the partition plate through which the shroud extends. This integration eliminates the space gap between separate components, achieving compact arrangement while maintaining cooling air flow guidance function
Solution Approach 2:
The partition plate serves multiple functions: it separates the prime mover room from the cooling device area, provides mounting support for the shroud, and maintains structural integrity. This multi-functionality reduces the need for additional components and optimizes space utilization
2Reliability
If cooling devices are arranged beside the prime mover, then cooling function is provided, but space efficiency is reduced due to gaps around the shroud
Solution Approach 1:
The shroud and partition plate are combined into a unified structure where the shroud extends through an opening in the partition plate. This merging eliminates gaps and achieves compact arrangement of cooling devices while maintaining reliable cooling function
Solution Approach 2:
The shroud is nested through the opening of the partition plate, with the partition plate serving as the outer structure and the shroud as the inner component. This nesting arrangement optimizes space utilization while ensuring cooling functionality

AI summary
A working machine includes a machine body, a prime mover on the machine body, at least one cooling device provided at one side of the prime mover, a shroud to guide a cooling air flow for cooling the at least one cooling device, and a partition plate to separate a prime mover room to house the prime mover from an area where the at least one cooling device is provided. The partition plate includes an opening to allow the shroud to extend therethrough and a mounting portion at which the shroud, which extends through the opening, is attached to the partition plate.
