Solution Overview

Problem

Existing heat exchanger systems with compact geometry face challenges in minimizing overall bulk and accessibility due to the increased size caused by external filter units connected via linear connections, which can hinder installation and removal processes.

Innovation Solution

A system where the filter unit is directly mounted on the heat exchanger's wall, using attachment means to position the filter in close proximity to the heat exchanger, reducing the overall bulk by eliminating the need for external connections, allowing for compact and efficient installation and removal.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If filters are connected externally to the heat exchanger using linear connections, then the filters can be easily installed and removed, but the overall bulk and height of the system increases

Engineering Contradiction:
ImproveEase of filter installation and removalVSAvoidOverall bulk of heat exchanger system
Core Design Contradiction:
Ease of operationVSVolume of stationary object

Solution Approach 1:

The filter unit is merged with the heat exchanger by integrating the filter housing directly onto the heat exchanger body. The linear connection is eliminated and replaced with a direct mounting arrangement where the filter sits adjacent to the heat exchanger with its passage ways in close proximity to the heat exchanger wall, reducing the overall system bulk while maintaining accessibility for filter installation and removal.

Inventive Principle:
Principle #5Merging (Combining)

2Volume of stationary object

If filters are mounted on lateral surfaces of the heat exchanger, then the system compactness is improved, but accessibility for maintenance is reduced

Engineering Contradiction:
ImproveSystem compactnessVSAvoidAccessibility for filter maintenance
Core Design Contradiction:
Volume of stationary objectVSEase of operation

Solution Approach 1:

The filter unit is positioned at a specific location on the heat exchanger where both compactness and accessibility requirements are satisfied. The containing body with passage ways is mounted adjacent to the heat exchanger wall in a position that allows easy access for filter installation and removal while maintaining close proximity to minimize overall system bulk.

Inventive Principle:
Principle #3Local quality

AI summary

A filter unit comprises at least a filter (25) mounted upstream and/or downstream of a delivery pipe (12) and/or an outlet pipe (14) disposed on a wall (11) of a heat exchanger (20). The filter (25) is provided with filter means (18) contained in a seating made in a containing body (16) which has passage ways (28) that put the seating in communication with the delivery pipe (12) and/or the outlet pipe (14) and which comprises first attachment means (22). A second attachment means (24) is provided, made directly on the wall (11), mating with the first attachment means (22) and cooperating therewith so as to mount the filter (25) on the wall (11), so that during use the passage ways (28) are adjacent and in close proximity to the wall (11).
