Abstract: A machine system includes a compressor, and a cooler having an inlet tank to receive compressed air from the compressor, and a header assembly attached to the inlet tank and including a plurality of cooling tubes supported in the header and each having an external heat exchange surface exposed to a flow of cooling air. The cooler further includes a plurality of graphite pack seals each extending peripherally around one of the cooling tubes, and a clamping assembly clamping the pack seals against the header to squeeze the pack seals into sealing contact with the cooling tubes and the header.

Abstract: A radiator includes a radiator frame, an array of tube assemblies each including a coolant tube and a tube clip supported in the radiator frame, and a lateral bump stop fitted between the array of tube assemblies and the radiator frame. The lateral bump stop includes cushions arranged in a staggered cushion pattern complementary to a staggered packing pattern of the tube assemblies with each of the cushions in contact with the tube clip of one of the tube assemblies.

Abstract: An air-to-air aftercooler (ATAAC) configured to cool compressed air from an air compressor is disclosed. The ATAAC may comprise a header at a cold end, and a plurality of core tubes. Each of the core tubes may have a first end and a second end. The ATAAC may further comprise a plurality of grommets each connecting the second end of one of the core tubes to a slot of the header. Each of the grommets may include an inner surface contacting the core tube and an outer surface contacting the slot of the header. The inner surface of the grommet may include radially-inwardly projecting regions contacting the core tube, and depressed regions providing clearance between the grommet and the core tube.

Abstract: An air-to-air aftercooler (ATAAC) configured to cool compressed air from an air compressor is disclosed. The ATAAC may comprise a first header. The first header may include a plurality of slots each having a recessed groove. The ATAAC may further comprise a plurality of core tubes each including a first end inserted in a respective one of the slots of the first header. The ATAAC may further comprise a plurality of mechanical joints each connecting the first end of one of the core tubes to the first header. Each of the mechanical joints may include a C-ring inserted in the recessed groove of one of the slots, and a clamp clamping the core tube to the first header. The C-ring and the clamp may both be formed from a metallic material.
