Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of sensor packaging, in particular to an anti-disturbance packaging of a temperature sensor with a honeycomb sandwich structure. Background Art
[0002] With the rapid development of information technology and the internet, new sensing and advanced manufacturing technologies are continuously advancing towards intelligence. Supporting materials for next-generation intelligent manufacturing equipment, capable of sensing, analyzing, reasoning, decision-making, and controlling, and enabling efficient, high-quality, energy-efficient, environmentally friendly, safe, and reliable production, will be urgently needed for the future development of the materials industry. With the rapid advancement of aerospace technology and the increasing frequency of spacecraft launches, the impact of temperature on spacecraft and the various electronic, electrical, and information technology devices within them can no longer be ignored. Consequently, the demand for obtaining and monitoring the operating temperature of internal spacecraft components is increasing.
[0003] To monitor the engineering health of a spacecraft's thermal protection system and heat-bearing structures, it's essential to obtain real-time operating temperatures of hot-end components. To ensure the proper functioning of temperature sensing equipment in complex environments, careful consideration must be given to temperature sensor protection during the structural design phase. Ignoring this issue can lead to significant vibration interference during operation, particularly in aircraft engine combustion chambers and turbine blades, due to the significant thermal vibrations often associated with their operation. Furthermore, aircraft engine combustion chambers often emit small solid particles during operation, which can easily damage the sensor structure. Therefore, addressing sensor packaging issues promptly, particularly improving the operational stability of temperature sensors operating in complex and harsh environments, enhancing their anti-interference capabilities in complex vibration environments, and strengthening the protection of the temperature sensor element, are crucial aspects of temperature sensor structural design. Structural packaging design must specifically consider enhancing the mechanical stability and anti-disturbance performance of the temperature sensor element, while also preventing solid particles from contacting or colliding with the element while ensuring contact with the ambient air surrounding the device under test.
