A self-fixturing fan shroud (12) for use with a heat exchanger assembly (13), the heat exchanger assembly (13) includes an upper horizontal surface (16), a lower, upwardly opening, horizontal channel (18), and at least one core (14 or 15) extending between the upper horizontal surface (16) and the c

A self-fixturing fan shroud (12) for use with a heat exchanger assembly (13), the heat exchanger assembly (13) includes an upper horizontal surface (16), a lower, upwardly opening, horizontal channel (18), and at least one core (14 or 15) extending between the upper horizontal surface (16) and the channel (18). Each of the cores (14 and 15) has a front face (24), a back face (26), and air flow passages extending from the front face (24) to the back face (26). The fan shroud (12) comprises a covering portion (28) having an opening (30) disposed therethrough. The opening (30) is of a predetermined size sufficient to receive a fan. An upper horizontal flange (38) extends from the covering portion (28) to rest on the upper horizontal surface (16) of the heat exchanger assembly (13) to vertically locate the fan shroud (12) relative to the heat exchanger assembly (13). A lower vertical flange (40) extends downwardly from the covering portion (28) to be received in the lower horizontal channel (18) of the heat exchanger assembly (13) to restrict movement of the fan shroud (12) away from the heat exchanger assembly (13).

1. 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. 2. The self-fixturing fan shroud of claim 1 wherein the upper horizontal flange extends substantially the length of the at least one core. 3. A heat exchanger assembly comprising: an upper horizontal surface; a lower, upwardly opening, horizontal channel spaced a given distance away from and opposite to the upper horizontal surface, the channel defined by a vertical surface extending upwardly from a lower horizontal surface; at least one core extending between the upper horizontal surface and the lower horizontal channel having a front face, a back face, and air flow passages extending from the front face to the back face; and a self-fixturing fan shroud to direct air flow between the at least one core and a fan, the shroud including an upper horizontal flange resting on the upper horizontal surface to vertically locate the fan shroud relative to the heat assembly, the upper flange being planar and having a uniform thickness; and a lower vertical flange received in the lower horizontal channel to restrict movement of the fan shroud away from the heat assembly, the lower flange being planar and having a uniform thickness. 4. The heat exchanger assembly of claim 3 wherein the upper horizontal flange of the fan shroud extends substantially the length of the at least one core.
