A heat exchanger assembly including an elongated tubular heat exchanger enclosure defining an interior chamber. A tube sheet is positioned within the interior chamber of the heat exchanger enclosure separating the interior chamber into a shell side and a channel side. The interior portion is configured to removably receive a tube bundle positioned within the shell side of the interior chamber. An annular sleeve member is positioned within the channel side of the interior chamber of the heat exchanger enclosure. An annular elastic torsion member is positioned within the channel side of the interior chamber of the heat exchanger such that the sleeve member is positioned between the tube sheet and the elastic torsion member. The elastic torsion member has an inner circumference deflectable relative to its outer circumference for torsioning the elastic torsion member.

A split ring includes a split ring body, the body having a first end and a second end; a first fastener hole defined by the first end of the split ring; a second fastener hole defined by the second end of the split ring; a gap defined by the first and second ends approaching each other wherein the first fastener hole and the second fastener hole are aligned to permit a fastener to extend through the first fastener hole, across the gap and through the second fastener hole; and a protrusion extending beyond the body of the split ring, the protrusion being located on the body opposite the gap. A method of forming a split ring includes: forming a split ring body; fixing onto the body a projection that projects above the body; and installing a closing mechanism into the split ring in order to allow the split ring to tighten over an object.

The invention relates to an ATAAC having a header, a plurality of slots defined in the header, a plurality of core tubes coupled to the header, and a plurality of joint assemblies to couple the header with the plurality of core tubes. Each of the plurality of joint assemblies includes an adapter, a sleeve, and a nut. The adapter further includes a first section threadedly engaged with one of the plurality of slots. The adapter further includes a tapered section inserted inside a flared end portion of one of the plurality of core tubes. Furthermore, the adapter includes a second section defined between the tapered section and the first section. The sleeve disposed around the one of the plurality of core tubes, the sleeve is engaged with the flared end portion of the one of the plurality of core tubes. The nut is engaged with the sleeve and the second section of the adapter.

An example memory module cooler may include a first liquid manifold, a second liquid manifold, and a cooling tube connected to the first and second liquid manifolds such that. The cooling tube may be connected to the manifolds such that (1) liquid coolant can flow from the first liquid manifold through the cooling tube to the second liquid manifold, and (2) the cooling tube can be rotated relative to the first and second liquid manifolds around a longitudinal axis of the cooling tube. The cooling tube may have an oblong cross-sectional profile.

A method including punching a first hole in a parent sheet metal, such that a substantially round section with a first diameter is removed from the hole, forming a second hole by inserting a mandrel into the first hole, causing a portion of the parent sheet metal to deform in a downward direction and increase the diameter of the first hole to a second diameter, the deformed portion of the parent sheet metal is substantially perpendicular to the parent sheet metal, forming a thread into an interior sidewall of the second hole, and forming the parent sheet metal into a water tight manifold.

A mounting assembly for mounting a heat exchanger comprises an elongate member defining a screw threaded axial bore at each end, and a bolt for each screw threaded bore. The assembly further comprises two elastomeric parts each being substantially top hat shaped and defining an axial bore to receive one end of the elongate member, such that the assembly can be mounted between two apertured mounting parts by arranging the heat exchanger between the mounting parts, with the elongate member received in a bore through the heat exchanger, and tightening the bolts so that the mounting part is clamped between the end of the elongate member and the bolt head, with the elastomeric parts mounting the mounting assembly in the heat exchanger bore so that resilient compression of the elastomeric parts allows movement of the heat exchanger with respect to the elastomeric parts.

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.
