Abstract
An engine housing includes a rotor housing and a side housing assembly. The rotor housing extends about an axis to form a rotor cavity of the engine housing. The side housing assembly includes a side housing body, a side plate, and an impingement cooling assembly. The side plate is disposed between the rotor housing and the side housing body. The side plate forms the rotor cavity. The impingement cooling assembly includes a first baffle plate. The first baffle plate is disposed between the side housing body and the side plate. The side housing body, the side plate, and the first baffle plate form a coolant passage. The coolant passage includes an inlet plenum and a plurality of impingement cooling holes. The first baffle plate forms the plurality of impingement cooling holes. Each impingement cooling hole of the plurality of impingement cooling holes is disposed at the inlet plenum.
