Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The heat transfer efficiency of existing heat transfer devices is compromised due to insufficient pressure causing inadequate fluid flow in the condensing portion, leading to reduced heat transfer, or excessive pressure resulting in reduced contact area and inefficient heat transfer.
Innovation Solution
A heat transfer device with a sealed bag and a contact component featuring a first and second contact portion separated by a spacer, allowing the side edge of the bag to expand and contact the component, adjusting pressure to ensure efficient fluid movement and heat transfer, while preventing excessive pressure and maintaining contact area.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If the pressure to press the condensing portion against the heat receiving member is excessively large, then the contact area between the condensing portion and heat receiving member is improved, but the working fluid flow into the inner area of the condensing portion is insufficient
Solution Approach 1:
The contact component is segmented into a first contact portion and a second contact portion separated by a spacer. This segmentation creates multiple contact points that distribute the pressing force, allowing sufficient pressure for heat transfer while maintaining space for working fluid flow between the segmented contact portions.
2Quantity of substance
If the pressure to press the condensing portion against the heat receiving member is not sufficient, then the working fluid can flow into the condensing portion, but the airtight enclosure expands resulting in a decrease of contact area
Solution Approach 1:
By segmenting the contact component into multiple contact portions, the pressing force is distributed across multiple points rather than concentrated in one area. This allows the enclosure to expand slightly without losing overall contact area, as other segmented contact portions maintain contact with the heat receiving member.
Solution Approach 2:
The spacer introduces a spatial dimension between the first and second contact portions, creating a three-dimensional contact structure. This dimensional arrangement allows the enclosure to expand in certain directions while maintaining contact through the distributed contact portions in other dimensions.
3Productivity
If the pressure to press the condensing portion against the heat receiving member is optimized, then heat transfer efficiency is improved, but the structure becomes more complex
Solution Approach 1:
The contact component is divided into a first contact portion, a second contact portion, and a spacer connecting them. This segmentation allows each component to be simple in structure while collectively achieving the optimized pressure distribution needed for high heat transfer efficiency.
Solution Approach 2:
The contact component with its segmented structure serves multiple functions simultaneously: it provides distributed contact pressure for heat transfer, maintains spacing for working fluid flow, and accommodates enclosure expansion. This multi-functionality achieves optimized heat transfer without proportionally increasing structural complexity.
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
This configuration enhances heat transfer efficiency by allowing sufficient space for gas phase fluid movement and maintaining contact, even during expansion, thereby improving the overall performance of the heat transfer device.
Implementation Method 1
The working fluid that has received the heat is vaporized. As a result, the working fluid changes its phase to a gas phase. At this time, the working fluid absorbs heat of vaporization.
Implementation Method 2
The vaporized working fluid in the gas phase is condensed in the condensing portion. In the vaporizing portion, the working fluid releases the heat of vaporization absorbed during the vaporization.

AI summary
The heat transfer device includes a sealed bag, a working fluid, and a contact component. The working fluid is enclosed in the bag. The contact component includes a first contact portion and a second contact portion that are separated from each other via a spacer. A left edge portion of the bag is disposed between the first contact portion and the second contact portion. The left edge portion contacts the first contact portion and the second contact portion when the bag expands due to vaporization of the working fluid.
