Cylindrical Ceramic Heater with End-Placed Flanges
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional heaters experience heat loss and reduced heating performance due to the temperature distribution within the ceramic body, and structural issues lead to positional deviations and connection failures during the insertion and removal of heating targets.
Innovation Solution
A cylindrical heater design featuring a ceramic body with a heat element and flanges located near the ends, which reduces heat loss by avoiding the middle temperature region and enhances structural support and connection stability through strategically placed flanges and a peripheral wall.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If flanges are located at the middle of the ceramic body in the axial direction, then structural support is provided, but heat loss increases due to the middle temperature region
Solution Approach 1:
The flanges are strategically positioned at locations with different thermal characteristics along the axial direction of the ceramic body. Specifically, flanges are placed at the both ends and/or middle portion of the ceramic body, avoiding the high-temperature middle temperature region while maintaining structural support functionality. This local differentiation in flange placement optimizes both heat loss reduction and connection stability.
2Reliability
If multiple flanges are added to improve structural support, then connection stability increases, but device complexity increases
Solution Approach 1:
The ceramic body is divided into multiple axial regions (both end and middle portion), and flanges are segmented and placed at specific regions rather than uniformly distributed. This segmentation approach provides structural support at critical locations without requiring excessive flanges throughout the entire structure, thereby maintaining connection stability while controlling device complexity.
3Loss of energy
If flanges are positioned to avoid middle temperature region, then heat loss is reduced, but manufacturing precision requirements increase
Solution Approach 1:
The flange positions are predetermined during the design phase based on thermal analysis of the ceramic body, identifying optimal locations at the both ends and middle portion that avoid the high-temperature middle temperature region. By establishing these positions in advance, the manufacturing process has clear guidelines for flange placement, which helps manage precision requirements through proactive design rather than reactive adjustment.

AI summary
A heater includes a heater member and a peripheral wall. The heater member includes a cylindrical ceramic body, a heat element in the ceramic body, and multiple flanges fixed on an outer circumferential surface of the ceramic body and extending away from the outer circumferential surface. The peripheral wall surrounds the heater member in an axial direction and a circumferential direction. A first flange is located in one direction from a middle of the ceramic body in the axial direction, and a second flange is located in another direction from the middle of the ceramic body in the axial direction.
