Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing heat exchangers face challenges in simultaneously improving vibration damping and thermal insulation performance while maintaining high heat exchange efficiency, particularly in data centers with dense electronic instruments generating significant heat.
Innovation Solution
A heat exchanger design where the coolant flows through an obliquely installed header pipe within a box-shaped enclosure, featuring a seal section between the header pipe and the enclosure to prevent air leakage and enhance heat transfer efficiency, combined with flat heat transfer pipes arranged at intervals to increase the heat exchange area and utilize elastically deformable materials for improved insulation and vibration suppression.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If the header pipe is installed close to the enclosure inner surface to save space, then space efficiency is improved, but air leakage occurs and thermal insulation performance deteriorates
Solution Approach 1:
A seal section is introduced as an intermediary component between the header pipe and the enclosure inner surface. This seal section prevents air leakage while allowing the header pipe to be installed close to the enclosure, thus maintaining space efficiency. The seal section acts as a mediator that resolves the conflict between close installation and air tightness.
Solution Approach 2:
The sealing function is extracted from the header pipe structure itself and implemented as a separate seal section. This allows the header pipe to maintain its primary heat exchange function while the seal section specifically addresses the air leakage problem, enabling independent optimization of both functions.
2Volume of moving object
If the header pipe is installed close to the enclosure inner surface, then space efficiency is improved, but thermal insulation performance deteriorates
Solution Approach 1:
The seal section serves as a thermal insulation intermediary between the header pipe and the enclosure. It provides both sealing and thermal insulation functions, allowing close installation while preventing heat loss to the enclosure, thus maintaining both space efficiency and thermal insulation performance.
Solution Approach 2:
The seal section is made of elastically deformable material that likely combines sealing and thermal insulation properties. This composite approach allows a single component to address multiple issues (sealing and thermal insulation) simultaneously, resolving the contradiction between close installation and thermal insulation.
3Device complexity
If rigid installation is used for simple structure, then device complexity is reduced, but vibration damping performance deteriorates
Solution Approach 1:
The seal section is made of elastically deformable material that can flex and absorb vibrations. This flexible sealing approach maintains structural simplicity while providing vibration damping, resolving the contradiction between simple structure and vibration control.
Solution Approach 2:
The material property of the seal section is changed to be elastically deformable, which provides vibration damping capability. This parameter change (from rigid to elastic) allows the structure to remain simple while gaining vibration absorption functionality.
