Discussion Overview
The discussion revolves around the design of an ohmic heating source intended to heat the glue of a hockey stick blade. Participants explore various approaches to achieve high temperatures (500-1000°F) using a 120VAC power source, focusing on wire materials, geometry, and safety considerations.
Discussion Character
- Technical explanation
- Debate/contested
- Experimental/applied
Main Points Raised
- One participant, identifying as an ME, seeks advice on wire gauge, cross-section, and materials for an ohmic heat source, suggesting a design similar to resistance wires used in blow dryers or heat guns.
- Another participant suggests using nichrome wire for heating elements and questions the need for a custom heater due to the geometry of the hockey stick blade.
- A different participant proposes using a hot air gun within a thermally insulated enclosure as an alternative to homemade heating elements, emphasizing safety and practicality.
- A clarification is made regarding the power source, correcting it from 120VDC to 120VAC, and noting that the current phase is purely design-oriented without plans for prototyping.
- One participant highlights the importance of establishing the power requirements for effective design and suggests that off-the-shelf heaters may simplify the process.
Areas of Agreement / Disagreement
Participants express varying opinions on the best approach to heating, with some advocating for off-the-shelf solutions while others explore custom designs. There is no consensus on the optimal method or materials to use.
Contextual Notes
Participants have not fully established the power requirements or the specific design constraints, which may affect the feasibility of proposed solutions. Safety considerations regarding homemade heating elements remain unresolved.
