Dustproof Net Installation Structure for Engine Cooling Systems
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional dustproof net installations in construction machines are limited by the mounting positions and dimensions of heat exchangers, making detachment and attachment difficult, restricting net size, and requiring multiple types of nets for different machines, leading to complexity in manufacture and maintenance.
Innovation Solution
A dustproof net installation structure that is independent of heat exchanger mounting positions and dimensions, using holding strips to securely attach and guide cooling air through the net, allowing for a standardized design that can be used across various machines, facilitating maintenance and reducing manufacturing costs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the dustproof net is fixedly secured on the sealed frame with the condenser held thereon, then the dustproof net can be arranged at a position upstream of the condenser, but the installation position is determined by the mounting positions of heat exchangers, making detachment and attachment work difficult
Solution Approach 1:
The dustproof net is divided into a net section and a frame section that can be detached from each other. The frame section is secured to the sealed frame, while the net section can be removed and replaced independently, facilitating maintenance work without requiring removal of the entire assembly
Solution Approach 2:
The net section is extracted as a separate removable component from the frame section. This allows the net to be easily detached for cleaning or replacement while leaving the frame section mounted on the sealed frame, significantly improving maintenance accessibility
2Adaptability or versatility
If the dustproof net is fixedly secured on the sealed frame with the condenser held thereon, then the dustproof net can be arranged in isolation from the condenser, but the shape and dimensions are determined by the sealed frame, restricting enlargement
Solution Approach 1:
The frame section is designed with a standardized structure that can accommodate different net sections with varying shapes and dimensions. This universal frame design allows the dustproof net system to be adapted to different applications and scaled up or down without requiring custom frame designs
Solution Approach 2:
The dustproof net system transitions from a fixed, rigid structure to a more dynamic configuration where the net section can be independently replaced and resized. This allows the system to adapt to different spatial requirements while maintaining the same mounting interface on the sealed frame
3Ease of manufacture
If the dustproof net is fixedly secured on the sealed frame with the condenser held thereon, then the dustproof net can be arranged at a position upstream of the condenser, but manufacturing multiple types of dustproof nets for different machines becomes necessary
Solution Approach 1:
The frame section is designed as a universal mounting structure that can accommodate different net sections. This standardization allows a single frame design to be used across multiple machine types, reducing the number of unique components that need to be manufactured and stocked
Solution Approach 2:
By separating the frame section from the net section, the invention allows standardization of the frame component while permitting customization of the net section. This segmentation enables manufacturers to produce standardized frames in volume while only needing to manufacture different net sections when specific applications require them

AI summary
Disclosed is an installation structure for a dustproof net to be arranged in a machine, which has an engine, a cooling fan for producing cooling air to cool the engine, plural heat exchangers arranged on an upstream side of the cooling fan, and a compartment with the engine, cooling fan and plural heat exchangers accommodated therein, such that the dustproof net is arranged at a position on a side upstream of the heat exchanger located most upstream among the plural heat exchanger relative to a flow of air drawn in by the cooling fan and in isolation from the most upstream heat exchanger to remove dust contained in the air drawn in by the cooling fan. The dustproof net is provided with a support structure for supporting the dustproof net on members that form the compartment.
