Partially Deformable Heat Exchanger Surface for Contact Alignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing heat exchangers face poor heat exchange due to misalignment between the heated portion and the heat source surface caused by assembly errors, leading to inadequate surface-to-surface contact.
Innovation Solution
A heat exchanger device with a partially deformable heated surface, featuring a first and second plate with an elastic member and a flexible portion, allowing the heated surface to adapt to the shape of the heat source for improved contact.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If the heated portion is rigidly fixed to the circuit board, then the structural stability is improved, but the contact error between the heated portion and heat source surface increases due to assembly errors
Solution Approach 1:
The heated portion is designed with a flexible base layer that allows dynamic adjustment and deformation to adapt to surface irregularities of the heat source, transforming the rigid structure into a semi-flexible one that can compensate for assembly errors while maintaining stability
Solution Approach 2:
The material properties of the heated portion are changed by using a flexible base layer with specific elasticity parameters, allowing the heated portion to deform within certain limits to improve contact with the heat source surface while maintaining structural integrity
2Stability of the object's composition
If fasteners are used to fix the heat exchanger, then the structural stability is improved, but the heat exchange efficiency deteriorates due to poor surface-to-surface attachment
Solution Approach 1:
The heated portion uses a flexible base layer that can conform to the heat source surface, replacing the need for fasteners and their associated gaps, thereby improving surface-to-surface attachment quality and heat exchange efficiency while maintaining structural stability
Solution Approach 2:
The design eliminates fasteners from the attachment mechanism by using the flexible properties of the base layer itself to achieve both structural stability and good thermal contact, removing the harmful element (fasteners) that created gaps and poor attachment
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Ensures better surface-to-surface contact and enhances heat exchange efficiency by allowing the heated surface to deform and conform to the heat source's surface, mitigating assembly errors.
Implementation Method 1
The elastic member is disposed between the heated surface and the first plate as elastic support
Implementation Method 2
The heated portion is attached to a surface of a heat source to be cooled, thereby helping the heat source to dissipate heat through heat exchange

AI summary
A heat exchanger includes a first plate, a second plate and an elastic member. The second plate is disposed on the first plate. A chamber is defined between the first plate and the second plate. The elastic member is disposed between the first plate and the second plate. The second plate has a surrounding portion and a heated surface in the surrounding portion as one piece. A flexible portion is integrally connected between the heated surface and the surrounding portion. The flexible portion surrounds a periphery of the heated surface to hang the heated surface in the surrounding portion. The elastic member is disposed between the heated surface and the first plate as elastic support. The flexible portion can provide the heated surface ability of partial deformation to improve the contact effect between the heated surface and a surface of a heat source to maintain great heat exchange ability.
