Solution Overview
Problem
Existing heat conduction devices face challenges in uniformly controlling temperature across a surface, particularly in transferring heat from a heat source to distant areas without discomfort, as they often result in temperature differences that can feel unpleasant to the human body.
Innovation Solution
A heat conduction device with a heat source portion, temperature control surface sectioned into multiple sections, and heat transfer portions that connect the heat source to these sections, using thermal resistance adjusters and high thermal conductivity materials to manage thermal resistance and ensure uniform temperature distribution.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If heat is transferred from a heat source to distant areas using conventional heat conduction devices, then heat transfer capability is improved, but temperature uniformity deteriorates causing uncomfortable temperature differences
Solution Approach 1:
The temperature control surface is divided into multiple temperature control sections (first, second, third sections) at different distances from the heat source. Each section is independently connected to the heat source through separate heat transfer portions, allowing individual temperature management for each zone rather than treating the entire surface as a single unit.
Solution Approach 2:
Different heat transfer portions are designed with different thermal conductivities matched to their specific distance requirements. The first heat transfer portion (closest to heat source) has lower thermal conductivity, while the second and third portions (farther away) have higher thermal conductivity. This local optimization ensures each region receives appropriate heat transfer to maintain uniform temperature across the entire surface.
2Temperature
If the temperature control surface is sectioned into multiple sections with different thermal conductivities, then temperature uniformity is improved, but device complexity increases
Solution Approach 1:
Multiple heat transfer portions with different thermal properties are integrated into a single temperature control surface structure. The first, second, and third heat transfer portions are combined with their respective temperature control sections to form a unified device that maintains temperature uniformity without requiring separate independent systems for each zone.
