Claim:
1. A heat exchanger for use in cooling a flow of compressed gas with a flow of cooling fluid, the heat exchanger comprising: a body portion having a first end, a second end, and a space between the first end and the second end, the space defining a minimum space diameter; a tube bundle including a first tube sheet, a second tube sheet, and a plurality of tubes extending between the first tube sheet and the second tube sheet, the first tube sheet and the second tube sheet positioned at opposing ends of the plurality of tubes to define a maximum tube bundle diameter that is less than the minimum space diameter such that either end of the tube bundle is insertable into the space from either the first end or the second end of the body portion; a first head including an inlet and an outlet, the first head removably connected with a fastener to the first end and connectable to the second end; a second head removably connected with a fastener to the second end and connectable to the first end such that cooling fluid enters the inlet, passes through a portion of the plurality of tubes, contacts the second head and flows through a second portion of the plurality of tubes to the outlet; wherein the body portion defines a first length between the first end and the second end, and the tube bundle defines a second length between the first tube sheet and the second tube sheet, the second length being greater than the first length; and wherein the first head and the second head completely support the tube bundle within the space; wherein the first head and the second head completely support the tube bundle within the space such that the tube bundle is held in position without contact of the body portion; and wherein all portions of the first and second heads are positioned external to the body portion.
