Heating Device Uniform Plate Heating via Fluid Gap
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing heating apparatuses fail to achieve uniform heat transfer when a target object is heated with its entire face in contact with a mount table, leading to non-uniform heating of the target object.
Innovation Solution
A heating apparatus with a heater and a support member that maintains a predetermined clearance between the heater and the target object, allowing a fluid to be present without inducing convection, enabling heat transfer via the fluid to heat the target object uniformly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the target object is heated with its entire face in contact with the mount table, then the heating process is simple, but uniform heat transfer cannot be achieved and the target object cannot be heated uniformly
Solution Approach 1:
A support member with projections is introduced as an intermediary between the mount table and the target object. The projections contact the target object at specific points rather than allowing full-face contact, enabling uniform heat transfer while maintaining structural support. This mediator structure resolves the contradiction by providing both mechanical support and controlled thermal contact.
Solution Approach 2:
The support member is segmented into multiple projections distributed across its surface. Each projection independently contacts the target object at a specific location, dividing the heating function into multiple discrete contact points. This segmentation ensures uniform heat distribution across the target object's face while maintaining simplicity in the overall heating apparatus design.
2Manufacturing precision
If a clearance is maintained between the heater and the target object to allow fluid presence, then uniform heat transfer is achieved, but the device complexity increases
Solution Approach 1:
The support member with projections automatically maintains the required clearance between the heater and the target object through its own structural design. The projections provide both support and spacing functions simultaneously, eliminating the need for additional complex positioning mechanisms. This self-service approach achieves uniform heat transfer while minimizing device complexity.

Function Achieved in This Case
The apparatus ensures uniform heating of the target object by transferring heat through the fluid, preventing direct heat transfer and convection, thus maintaining consistent temperature across the object's surface.

AI summary
Provided are a heating device, and a method for manufacturing a plate-shaped member, with which it is possible to uniformly heat an object to be heated. The heating device 1 is provided with: a heater 10 for generating heat to be applied to a member W to be heated; and a support member 20 for supporting a surface Wf of the member W to be heated, the support member 20 being provided to a surface 11f of the heater 10. The support member 20 supports the member W to be heated so that heat is not directly conducted between the surface Wf of the member W to be heated and the support member 20, and so that the gap between the surface 11f and the surface Wf of the member W to be heated is kept at a prescribed spacing S at which a fluid is present in the gap but does not undergo convection. In the method for manufacturing a plate-shaped member, a member W to be heated is supported by a support member 20, the member W to be heated is heated by a heater 10, and a plate-shaped member is manufactured.
