Abstract:
A variable are a heat sink comprising:a first heat sink area;a second heat sink area separated from the first heat sink area;a third heat sink area separated from the first and second heat sink areas;a first thermally responsive bridge thermally coupling the first heat sink area and the second heat sink area, the first bridge including a first metallic member adhered to an adjacent second metallic member, the first bridge thermally decoupling the first and second heat sink areas in response to the first, second and third heat sink areas having a combined first temperature higher than the temperature of the first heat sink area; anda second thermally responsive bridge thermally coupling the second heat sink area and the third heat sink area, the second bridge including a first metallic member adhered to an adjacent second metallic member, the second bridge thermally decoupling the second and third heat sink areas in response to the second and third heat sink areas having a combined second temperature, greater than the first temperature.
