Abstract
A heat exchange assembly includes an induced draft arrangement for simultaneously inducing drafts in right and left heat exchangers mounted on a common support. A plurality of fans are disposed with a common axis of rotation and draw air through the right and left heat exchangers, the air then being deflected upwardly by a series of venting walls associated with the fans on a one to one basis. The heat exchangers are bolted to support posts along a support and are spaced from the venting walls to maximize heat dissipation capacity.
Claims18
A heat exchanger assembly for air-cooled heat exchanging and having a top, a bottom, a front end, a back end, a right side and a left side:
- (a) a plurality of air flow units arranged and supported in a longitudinal end-to-end assembly, each air flow unit including the following associated components:
- (i) a substantially vertical fan mounting wall having a hole therein;
- (ii) a fan mounted for rotation in said hole,
- (iii) a venting wall operative to direct air blown backwardly by said fan up and out said top, said venting wall situated in back of said fan mounting wall and including right and left portions and an inclined portion extending from adjacent the bottom of said fan mounting wall to the top of said heat exchanger,
- (iv) right and left air inlets situated in front of said fan mounting wall,
- (v) an air inlet zone between said right and left air inlets from which air is drawn to said fan, through said hole, and into a venting zone defined by said venting walls, and
- (vi) a bottom wall portion closing off the bottom of said air inlet zone,
- (b) right and left heat exchangers extending lengthwise along said heat exchanger assembly and respectively covering said right and left air inlets of said air flow units and respectively covering said right and left portions of said venting wall of at least one of said air flow units,
- (c) a support supporting said air flow units and said heat exchangers, and
- (d) coupling means for coupling said fans together for rotation in unison and in parallel and wherein said fans are adapted to cause air flow through said right and left heat exchangers into said air inlet zones by way of said right and left air inlets, through said holes into said vent zones and out the top of said vent zones and wherein said right and left portions of the venting walls of more than one of said air flow units are tapered inwardly and backwardly.
