TWO-STATE SYSTEM FOR THERMAL REGULATION OF AN ELECTRONIC DEVICE

摘要

The invention concerns a system (1) comprising an electronic device (2) generating thermal energy and a radiator (5) and capable of adopting two active and inactive configurations with the radiator (5) in contact with or spaced apart from the electronic device (2), a thermal actuator (7) controlling the shift from the active configuration to the inactive configuration when the temperature in the vicinity of the device (2) drops below a first predetermined threshold and from its inactive configuration to its active configuration when the temperature in the vicinity of the device (2) rises above an second predetermined threshold; the actuator (7) comprises an element (18) made of shape-memory alloy in the form of a spring, for example an nickel-titanium, nickel-titanium-copper alloy.
