Abstract
Electrical and electromechanical devices often require maintaining a specific temperature, or a narrow range or temperatures, during operation. An assembly regulates the temperature of a device by providing a variable thermal resistance between the device and a heatsink. The device can be mounted to a base having a high thermal resistance, the base thermally isolating the device from the heatsink. At low environmental temperatures, the base enables the device to rise to its operating temperature as a result of the device's waste heat, and with no or minimal use of a heater. As the environmental temperature increases, a working fluid, having a low thermal resistance, undergoes thermal expansion to fill a portion of a volume in the base between the device and the heat sink, lowering the thermal resistance between the device and the heatsink to maintain the device at the required operating temperature.
