Variable Thermal Resistance

In the world of electrical and electromechanical devices, maintaining a specific operational temperature is a critical aspect of reliability and performance. Devices not operating within the appropriate temperature range can result in compromised performance, shorter device lifespan, or even complete failure. To address these issues, heat-management techniques are typically employed to disperse excessive heat and maintain optimal device temperatures. Current traditional approaches to thermal management in these devices involve fans or other mechanical means to dissipate heat. However, active cooling methods like these can be energy-intensive, increase the complexity of the device, and present additional points of mechanical failure. Moreover, these methods do not adjust well to rapid alterations in environmental temperatures. Consequently, a solution that provides efficient, adaptable, and less energy-intensive heat management is highly desirable.

Technology Description

This innovative technology is a temperature regulation system for electrical and electromechanical devices. The assembly facilitates consistent temperature by providing a variable thermal resistance between the device and a heatsink. The device can be installed on a base that has a high thermal resistance, allowing it to be thermally isolated from the heatsink. The base allows the device to rise to its working temperature using the waste heat it generates, limiting or negating the need for a heater at low environmental temperatures. When the environmental temperature climbs, a working fluid with low thermal resistance undergoes thermal expansion. This process fills a part of the volume in the base between the device and the heatsink, subsequently reducing the thermal resistance between them. This ingenious mechanism keeps the device at the necessary operating temperature, allowing for enhanced temperature regulation and resource efficiency.
