Abstract
An air-cooled subsurface vault houses a wireless power transfer charger for charging electric vehicles. The vault includes a cavity that receives the wireless power transfer charger and includes an air space around the wireless power transfer charger. At least two grates are positioned on respective sides of the wireless power transfer charger to enable bi-directional air-flow between the surface and the air space around the wireless power transfer charger. A temperature control element is further provided to regulate a temperature within the cavity and the at least two grates. The temperature control element may further include a heat exchanger positioned within the air space of the vault. Each grate is further adapted to act as an inlet or an outlet for the heat exchanger. A controller may be used to control operation of the heat exchanger to control venting duration and a direction of air flow in the cavity.
