Winter front assembly for charge air cooled trucks and method

摘要

A winter front assembly (41) for mounting to a truck having a charge air cooler (22) mounted in front of a radiator (23) and radiator fan (24). The winter front is provided as a sheet-like cover member (42) with an opening (44) having a configuration exposing at least a portion of each of the core tubes (29) in the charge air cooler (22). The opening (44) further is substantially circumferentially balanced in an annular area in front of the tips (53) of the radiator fan (24). The winter front (41) also includes an auxiliary cover member (61) formed for selective securement to the main cover member (42) to substantially reduce the area of the opening (44). The auxiliary cover (61) is configured to maintain direct air flow over at least a portion of each of the core tubes (29) and to maintain circumferentially balanced air flow to the radiator fan (24) in the annular area proximate the fan tips (53). A method of covering the front of a cooling system (21) with the winter front (41) also is provided.
