Segmented Air Jacket Thermostat for Uniform Chamber Temperature
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional thermostatic apparatuses with air jacket structures experience temperature unevenness inside the inner tank due to power-on timing and differences in temperature rise time between portions of the air jacket, leading to temperature shifts and distortion phenomena, which can be exacerbated by the installation of fans to address these issues.
Innovation Solution
A thermostatic apparatus with a separator dividing the air jacket structure into multiple chambers, where a thermostatic unit supplies temperature-controlled medium to each chamber, reducing temperature unevenness by compartmentalizing the air layer and maintaining consistent temperature distribution without the need for fans.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If a fan is installed to forcibly circulate the air layer, then temperature unevenness inside the inner tank is reduced, but the cost of the thermostat increases and vibrations occur
Solution Approach 1:
The air jacket structure is divided into multiple independent chambers using separators. Each chamber can be independently controlled by thermostatic units, allowing localized temperature adjustment. This segmentation eliminates the need for fan-driven circulation while achieving uniform temperature distribution through coordinated control of multiple zones.
Solution Approach 2:
The system employs dynamic control of multiple thermostatic units that can independently adjust their operation based on real-time temperature conditions in each chamber. This dynamic coordination allows the system to adapt to varying thermal conditions without mechanical moving parts, achieving temperature uniformity through intelligent control rather than physical circulation.
2Temperature
If a fan is installed to forcibly circulate the air layer, then temperature unevenness inside the inner tank is reduced, but vibrations occur and cost increases
Solution Approach 1:
The patent replaces the mechanical fan-based circulation system with a multi-zone thermostatic control system. Instead of using mechanical movement to achieve air circulation, the system uses multiple independently controlled thermostatic units that create localized thermal fields. This substitution eliminates vibrations entirely while achieving the same temperature uniformity goal through thermal management rather than mechanical mixing.
3Stability of the object's composition
If the air jacket structure is used for temperature control, then the thermostat can maintain constant temperature, but temperature unevenness occurs due to power-on timing and structural differences
Solution Approach 1:
The air jacket is segmented into multiple chambers with independent thermostatic control. This allows each zone to be optimized individually, compensating for structural differences in heat distribution. By controlling each segment separately, the system achieves both overall temperature stability and local temperature uniformity, eliminating the trade-off present in conventional single-zone systems.
Solution Approach 2:
Different regions of the air jacket are provided with independent thermostatic units that can be tuned to local conditions. This local quality approach allows each chamber to be optimized for its specific thermal characteristics, addressing power-on timing issues and structural variations in different parts of the jacket. The result is uniform temperature distribution while maintaining overall system stability.
