Abstract
In a furnace having a plurality of parallel heat exchanger panels over which circulation air is caused to flow, and which has a tendency for hot spots to occur at particular locations on its outboard heat exchanger panels, a diverter vane is placed on the outer side of each of the outboard heat exchanger panels to divert a portion of the circulation air to the hotspot locations for cooling them to acceptable temperatures. In one form, the diverter vane is integrally formed with, and extends normally inwardly from a side baffle that extends upwardly alongside the outboard heat exchanger panel. The diverter vane is obliquely disposed with respect to the side baffle, with its lower end located near a midpoint of the heat exchanger panel and its upper end located near the hotspot location. When used with a multipass heat exchanger panel, the hotspot location is between the end of the first return bend and the commencement of the second pass, and the diverter vane is thus positioned with its top end near that location. Where a blower shelf baffle is employed, the diverter vane lower end is positioned near that location.
