Abstract
A dynamic air baffle comprises: spaced-apart first and second plates configured to be positioned adjacent to at least one heat source to be cooled by an airflow; a heat insulator sandwiched between the first and second plates; and an air flap coupled to the first and second plates and extending into the airflow; wherein the first and second plates are configured such that a differential temperature between the first and second plates causes a differential expansion in lengths of the first and second plates, which rotates the air flap from a rest position, corresponding to when the differential temperature is zero, to a rotated position that is closer to a cooler plate and farther from a hotter plate of the first and second plates, such that the air flap directs more of the airflow to the hotter plate and less of the airflow to the cooler plate.
