Oscillator Thermal Uniformity via Intermediary Heat Diffusion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing oscillator devices experience non-uniform temperature distribution due to direct heat conduction from heat generators, leading to uneven heating of vibrator elements, which affects resonance frequency stability.
Innovation Solution
The implementation of a layered structure with higher thermal conductivity between the vibrator and heat generators, and between the heat generators themselves, to reduce temperature differences and ensure even heating, thereby stabilizing the resonance frequency.

1Use of energy by moving object
If heat from the heat generator directly conducts through the vibrator element, then heating efficiency is improved, but temperature distribution uniformity deteriorates
Solution Approach 1:
A heat diffusion plate is introduced as an intermediary component between the heat generator and the vibrator element. This plate has a larger area than the heat generator and diffusely distributes the heat across multiple points on the vibrator element, preventing localized overheating while maintaining efficient heat transfer. The plate acts as a thermal mediator that decouples the direct thermal path, thereby achieving both heating efficiency and temperature uniformity.
2Temperature
If a base plate heat conducting plate is provided, then overall heat conduction is improved, but direct heat conduction through the vibrator element remains dominant, causing temperature non-uniformity
Solution Approach 1:
The heating system employs multiple heat generators positioned at different locations (first and second heat generators) rather than a single centralized source. Each heat generator targets specific regions of the vibrator element, creating localized heating zones that collectively achieve uniform temperature distribution across the entire vibrator. This distributed heating approach addresses the local thermal requirements of different vibrator regions.
Solution Approach 2:
The heat diffusion plate serves as a thermal mediator between the heat generators and the vibrator element. It receives heat from multiple sources and redistributes it uniformly across the vibrator's surface, preventing direct concentrated heat paths while maintaining efficient thermal coupling. This intermediary structure enables the system to achieve both good overall heat conduction and uniform temperature distribution.

AI summary
An oscillator includes a container, a first heater disposed in a first area of the container, a second heater disposed in a second area of the container that is different from the first area, a vibrator disposed between the first area and the second area when viewed in the direction perpendicular to a surface on which the first heater is disposed, and a layer that is disposed between the vibrator and the container with at least part of the layer overlapping with the first heater, the second heater, and the vibrator when viewed in the direction perpendicular to the surface on which the first heater is disposed, and the thermal conductivity of the layer is higher than the thermal conductivity of the first and second areas.
