Patent ID: 8661803

Claim:
An apparatus for cooling exhaust gases from an engine exhaust, comprising: a first pipe forming a vertically directed outlet for an exhaust conduit; a second pipe mounted to receive an exhaust gas flow from the outlet of the first pipe, the second pipe having a diameter at least twice a diameter of the first pipe and positioned relative to the first pipe to define an ambient air annular inlet gap surrounding the outlet of the first pipe, the second pipe having a height that is at least 2.5 times a width of the inlet gap; and, a dispersing outlet mounted at an end of the second pipe and configured to direct exhaust gas radially outward, wherein the dispersing outlet comprises an end plate having a conical protrusion formed there on and directed into the exhaust flow, the plate being spaced from an end of the second pipe to define there between a radial outlet opening; and an unnular deflector plate mounted between the end of the second pipe and the end plate, the deflector plate having a downward facing frusto-conical protrusion wherein the annular defelctor plated has a centrally located hole sized to allow exhaust gas to pass there through.
