Solution Overview
Problem
Conventional temperature control units struggle to enhance the uniformity of in-plane temperature on the placement surface during changes in temperature rising rates.
Innovation Solution
The temperature control unit incorporates a substantially flat-plate-shaped placement section, a heating section, and a heat transfer section formed at least partially of a metal porous structure, with a housing that allows fluid flow and is partitioned to facilitate uniform heat transfer.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the temperature rising rate is increased to shorten takt time, then productivity is improved, but uniformity of in-plane temperature deteriorates
Solution Approach 1:
The heat transfer section is formed with a metal porous structure that has high thermal conductivity and large specific surface area. This porous structure enables rapid heat distribution across the placement surface, maintaining uniform in-plane temperature even when the temperature rising rate is increased to shorten takt time.
Solution Approach 2:
The invention changes the physical structure parameter of the heat transfer section from solid to porous form. This structural parameter change increases the heat transfer efficiency and thermal conductivity, allowing the system to achieve both fast heating (shortened takt time) and uniform temperature distribution across the placement surface.
2Productivity
If the temperature rising rate is changed during heating, then productivity is improved, but temperature uniformity across the placement surface deteriorates
Solution Approach 1:
The metal porous structure in the heat transfer section provides rapid thermal response capability. When the temperature rising rate is changed during heating, this porous structure quickly redistributes heat across the placement surface, preventing temperature non-uniformity and maintaining consistent heating quality throughout the process.
Solution Approach 2:
The porous heat transfer structure ensures continuous and uniform heat distribution across the placement surface throughout the heating process. This continuous heat transfer action maintains temperature uniformity even when the overall temperature rising rate is accelerated, ensuring that all regions of the placement surface receive heat continuously and evenly.
