Abstract
A degas bottle for inducing a cyclonic direction of flow to incoming coolant is disclosed. The degas bottle includes a body and an air separator having a cylindrical wall. An incoming coolant inlet is attached to the upper end of the air separator and is positioned at a tangent with respect to the cylindrical wall of the air separator, thus inducing cyclonic action as the coolant enters the air separator. The air separator may be of a cylindrical shape or of a conical shape. As air trapped coolant tangentially flows into the air separator, it will follow the cylindrical or conical shape of the air separator. The centrifugal force keeps the incoming coolant pressed against the inner wall of the air separator coolant on the wall while air separates from the coolant. The cyclonically flowing coolant circles downward to the reservoir while air remains on top of the coolant.
