Embodiment Construction

[0027] Reference is now made to the accompanying drawings, and with specific reference to figure 1 , the machine 10 is shown. Generally, the machine 10 may include an internal combustion engine 12 to provide power to drive the movement of the machine 10 , as well as other optional features, such as wheels 14 (or tracks), and an operator control station 16 . For example, machine 10 may be a mining truck 18, but it may also be other types of mobile or stationary machines, such as, but not limited to, wheel loaders, excavators, bulldozers, drills, power shovels, or material handlers. In other examples, machine 10 may be any type of mobile or stationary machine (manned or unmanned) that includes an air-to-air aftercooler (ATAAC) 20 for cooling compressed intake air (see figure 2 ).

[0028] go to figure 2 , the engine system 22 of the machine 10 is shown. The engine system 22 may include an intake system 24 that directs intake air to the internal combustion engine 12 for com...

Abstract

An air-to-air aftercooler (ATAAC) (20) configured to cool compressed air from an air compressor (26) is disclosed. The ATAAC (20) may include a header (52) at the cold end (46) and a plurality of core tubes (58). Each of the core tubes (58) may have a first end (60) and a second end (62). The ATAAC (20) may also include a plurality of gaskets (96) each connecting the second end (62) of one of the core tubes (58) to the groove (70) of the header (52). Each of the gaskets (96) may include an inner surface (101) contacting the core tube (58) and an outer surface (102) contacting the groove (70) of the header (52). The inner surface (101) of the gasket (96) may include a radially inwardly projecting region (104) that contacts the core tube (58), and a recessed region (106) that provides clearance between the gasket (96) and the core tube (58). ).

Description

technical field [0001] The present disclosure relates generally to air-to-air aftercoolers, and more particularly, to air-to-air aftercoolers having tube-to-manifold sliding joints. Background technique [0002] Engine systems used in many machines, vehicles, and equipment include intake systems that deliver intake air to an internal combustion engine for combustion with fuel. The intake system may include an air compressor that pressurizes intake air to force more air into the engine for combustion. At higher engine power densities, the temperature of the compressed air at the compressor outlet can approach or even exceed 350°C. In newer engine designs, higher compressor outlet temperatures may exist at higher engine power densities. [0003] To cool the compressed air prior to introduction into the engine, the intake system may also include an air-to-air aftercooler (ATAAC) downstream of the air compressor. The ATAAC may include an inlet end (or hot end) where the hot c...
