1. A wireless charging device comprising:
- an enclosure base;
a first inlet to receive ambient air, the first inlet proximate to the enclosure base;
an outlet to exhaust air, airflow from the inlet to the outlet based only on passive air convection;
an enclosure top having a portion that is inclined relative to the enclosure base, the inclined portion extending from the first inlet to the outlet, the outlet proximate to an apex of the inclined portion; and
a first power transmission antenna, an entirety of the antenna in physical communication with an inside surface of the inclined portion.

Abstract
A wireless charging device includes an enclosure base and an enclosure top. A portion of the enclosure top is inclined relative to the base. A power transmission antenna is disposed on an under-surface of the inclined portion. A first inlet is located proximate to the enclosure base for receiving ambient air. An outlet is located proximate to an apex of the inclined portion for exhausting air. Airflow from the inlet to the outlet is based only on passive air convection.

11. A wireless power transmission device comprising:
-
an enclosure including an enclosure base and an enclosure top, a portion of the enclosure top inclined relative to the enclosure base; a first inlet to receive ambient air; an outlet to exhaust air, airflow from the inlet to the outlet in response to a difference between a temperature of air proximate to the first inlet and a temperature of air proximate to the outlet; and a first power transmission antenna in physical communication with the inclined portion of the enclosure top, the inclined portion of the enclosure top extending from the first inlet to the outlet. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19, 20)
