Solution Overview
Problem
Existing fluid controller heating apparatuses face challenges in achieving superior heating performance and heat-insulation while requiring minimal space for installation, especially in integrated fluid control systems where space is limited and heat-insulation is crucial.
Innovation Solution
A cylindrical heater unit with heat-transfer members and a flexible cylindrical heat-insulation member that surrounds the heater unit, allowing for efficient heating from both sides and the entire circumference of the fluid controller, while the heat-insulation member can be easily installed from above, reducing space requirements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If a pair of plate-shaped side heaters are used to heat the fluid controller, then heating performance is improved, but the space required for installation increases
Solution Approach 1:
The heating device is segmented into a heater unit (containing the heating element) and a heat-insulation member unit. These separate units can be installed independently, with the heater unit fitting into a recess of the heat-insulation member, allowing compact installation in limited spaces while maintaining effective heating capability.
Solution Approach 2:
The heater unit is nested within the heat-insulation member by fitting the heater unit into a recess formed in the heat-insulation member. This nesting arrangement allows the heating element to be surrounded by insulation material, providing both heating function and thermal isolation in a compact configuration.
2Object-affected harmful factors
If heat-insulation members are used to prevent temperature rise of adjacent fluid controllers, then heat-insulation performance is improved, but the device complexity increases
Solution Approach 1:
The heat-insulation member is merged with the mounting structure by integrating the insulation function into the existing support block. The support block serves dual purposes: mechanically supporting the fluid controller and providing thermal insulation to adjacent components, thereby reducing overall device complexity.
Solution Approach 2:
The support block is designed with multi-functionality, serving both as a mechanical mounting structure and as a heat-insulation member. This universal component performs multiple functions simultaneously, simplifying the overall device structure while maintaining effective thermal isolation.

AI summary
A fluid controller heating apparatus includes a cylindrical heater unit that surrounds a portion of an opening-and-closing valve to be heated, and a heat insulation jacket that surrounds the heater unit. The heater unit includes a pair of heat-transfer members to which plate-shaped heaters are fixed, respectively. The heat-transfer members are mounted so as to hold the opening-and-closing valve therebetween from both sides and are capable of being coupled to each other with a screw member. The heat insulation jacket is a cylindrical integrated product.
