Abstract:
A seif-fixturing fan shroud for use with a heat exchanger assembly including an upper horizontal surface, a lower, upwardly opening, horizontal channel, and at least one core having a front face, a back face, and air flow passages extending from the front face to the back face, the at least one core extending between the upper horizontal surface and the lower horizontal channel, the lower channel defined by a vertical surface extending upwardly from a lower horizontal surface, the shroud comprising:a covering portion having an opening disposed therethrough, the opening being of a predetermined size sufficient to receive a fan; an upper horizontal flange extending from the covering portion to rest on the upper horizontal surface of the heat exchanger assembly to vertically locate the fan shroud relative to the heat exchanger assembly, the upper horizontal flange being planar and having a uniform thickness; and a lower vertical flange extending downwardly from the covering portion to be received in the lower horizontal channel of the heat exchanger assembly to restrict movement of the fan shroud away from the heat exchanger assembly, the lower vertical flange being planar and having a uniform thickness.
