Passive and no-loss weather cap for protection of wind induced downdraft in sensitive exhaust systems
The invention provides a device for removing heat from a building, the device having: a first tubular member defining a first cavity; a second tubular member defining a second cavity, whereby said second tubular member resides within the first cavity and is coaxial to the first tubular member; and a double conic body coaxially residing in the first cavity and coaxially positioned with the second tubular member.Also provided is a method for removing heat from a building, the method having the steps of: directing heat-containing exhaust emanating from a flue, defining a first diameter, to a passageway received by the flue, whereby the passageway defines a longitudinal axis and a periphery circumscribing the axis; forming the directed exhaust into a slipstream, wherein the slipstream generally travels along the longitudinal axis; and routing precipitation entering the passageway to the periphery.
