Problems solved by technology

These particles collect on the core of the heat exchanger and may build up over time, resulting in restricted airflow and reduced heat transfer.
Overheating of the engine may, therefore, occur when the accumulation of dirt and other particles on the heat exchanger core is sufficient to prevent proper heat transfer.
The heat exchanger core may become exceptionally clogged with debris before an operator addresses the need for cleaning.
In addition, the location of the h

Example

[0016]An exemplary embodiment of a machine 10 is shown generally in FIG. 1. The machine 10 may be a waste handling track type tractor, as shown, or any other vehicle having a heat exchanger system 20 (not shown). The heat exchanger system is located at a front end 12 of the machine 10 and is enclosed by a heat exchanger guard 14. The heat exchanger guard 14 includes at least one slot adapter 16, shown later in greater detail.

[0017]The heat exchanger system, shown generally at 20, can be seen in greater detail in FIG. 2. The heat exchanger system 20 may include an air to air aftercooler 22, a water cooling system 24, and a hydraulic oil cooler 26, all occupying a common plane and defining a core of the heat exchanger system. Although three heat exchangers are shown, those skilled in the art will appreciate that any number and type of heat exchangers may be used.

[0018]The heat exchanger system 20 is enclosed by heat exchanger guard 14. The heat exchanger guard 14 includes a first side...

Abstract

A machine having a heat exchanger system includes a heat exchanger guard including first and second sidewalls. The first sidewall is adjacent a core of the heat exchanger system. A first slot adapter is positioned over an opening formed in the first sidewall. The first slot adapter is vertically oriented and includes a first slot opening for receiving a compressed air cleaning wand therethrough. A cover is fixedly attached to the first slot adapter and is movable between an open position and a closed position.

Description

TECHNICAL FIELD[0001]The present disclosure relates generally to an access opening for cleaning a heat exchanger system of a machine, and more particularly to a slot adapter positioned over the access opening for receiving a compressed air cleaning wand therethrough.BACKGROUND[0002]Machines, such as, for example, off highway trucks, excavators, track type tractors, waste handlers, wheel loaders, scrapers and the like often operate in debris filled environments. Dust and other airborne particles are directed by the fan of the machine through the core of the heat exchanger system. These particles collect on the core of the heat exchanger and may build up over time, resulting in restricted airflow and reduced heat transfer. Overheating of the engine may, therefore, occur when the accumulation of dirt and other particles on the heat exchanger core is sufficient to prevent proper heat transfer.[0003]The heat exchanger core may become exceptionally clogged with debris before an operator a...
