Heat exchanger with radial baffles

A shell and tube type of heat exchanger in which ambient air is used as the cooling medium, comprising:

• a housing including a cylindrical peripheral wall having spaced parallel end walls forming a cylindrical core cavity,
• a fluid inlet and outlet means mounted on said housing for flow of fluid into and out of said cavity,
• a planar baffle mounted in said cavity and contacting said peripheral wall to divide said cavity into two chambers,
• said inlet means communicating with one chamber and said outlet means communicating with the other of said chambers,
• said end walls including a plurality of spaced apertures and having a face exposed to ambient air,
• a plurality of heat exchanger tubes mounted in said end walls and extending into said cavity and disposed in parallel relation between said end walls,
• said tubes being open at each end for passage through said tubes of ambient air to effect cooling of the fluid flowing through said cavity,
• said baffle having an aperture therein located to form a passageway from one to the other of said chambers in a region remote from said inlet and outlet means,
• each chamber including at least two spaced flanges extending radially inwardly of said cavity from said peripheral wall,
• at least the flanges closest to said inlet and outlet means being positioned between 40 and 55 degrees on either side of said baffle as measured from the center line of said cavity, and
• said inlet and outlet means each defining a conduit having an axis which is at an angle of about 30 degrees relative to a line tangent to said peripheral wall at the intersection of said axis with said peripheral wall.
