Solution Overview

Problem

Existing intercoolers suffer from gas leakage at the welding seam of their U-shaped housings, which compromises their sealing integrity.

Innovation Solution

The introduction of gas blocking portions that penetrate through the seam, integrated with the outer housing, to block airflow leaks, combined with a groove portion and sealing pieces to enhance sealing efficacy.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Volume of moving object

If a traditional separate mounting approach is used for the intercooler and engine components, then individual component functionality is maintained, but the overall engine bay packaging efficiency is reduced and component spacing is insufficient

Engineering Contradiction:
Improveengine bay packaging efficiencyVSAvoidmounting structure complexity
Core Design Contradiction:
Volume of moving objectVSDevice complexity

Solution Approach 1:

The intercooler is merged with the engine component mounting structure to form an integrated assembly. The intercooler housing serves dual functions as both a thermal management component and a structural mounting platform, eliminating the need for separate mounting brackets and reducing overall space requirements in the engine bay.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The mounting structure is designed to perform multiple functions simultaneously: it provides mechanical support for engine components, serves as a mounting platform for the intercooler, and incorporates fastening mechanisms. This multi-functionality reduces the number of separate parts needed and improves packaging efficiency.

Inventive Principle:
Principle #6Universality (Multi-functionality)

2Volume of moving object

If compact engine bay layout is implemented to improve packaging efficiency, then space utilization increases, but access for maintenance and repair becomes difficult

Engineering Contradiction:
Improvespace utilizationVSAvoidaccess for maintenance
Core Design Contradiction:
Volume of moving objectVSEase of repair

Solution Approach 1:

The integrated assembly is designed with modular characteristics, allowing the intercooler and engine components to be accessed and serviced relatively independently. The mounting structure incorporates features that facilitate disassembly and reassembly, enabling maintenance personnel to access components without requiring complete disassembly of the entire assembly.

Inventive Principle:
Principle #1Segmentation

3Volume of moving object

If insufficient spacing is provided between engine components and intercooler, then packaging efficiency improves, but heat dissipation effectiveness is reduced

Engineering Contradiction:
Improvepackaging efficiencyVSAvoidheat dissipation effectiveness
Core Design Contradiction:
Volume of moving objectVSTemperature

Solution Approach 1:

The intercooler is positioned and oriented in three-dimensional space to optimize both packaging and heat dissipation. The mounting structure incorporates strategic spacing in vertical and lateral dimensions, allowing adequate airflow paths for thermal management while maintaining compact overall dimensions. Airflow channels are designed to pass through specific gaps between components to ensure effective cooling.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

AI summary

An outer housing (100), a core body (300), and an intercooler, the outer housing comprising: a first housing (110) and a second housing (120); the first housing (110) abuts the second housing (120) on the second direction and forms a seam (140) that extends on the first direction, the first direction being perpendicular to the second direction; and air blocking portions (130) which extend on the second direction and pass through the seam (140) are formed between the first housing (110) and the second housing (120). The present invention may solve the problem in which airflow easily flows out of an intercooler along the extension direction of a gap when a gap appears at a welding position of two U-shaped housings.
