A shell tube and heat exchanger () includes a plurality of tubes surrounded by a shell (). Each tube () includes a plurality of indentations. A mold is placed in a desired positions and orientation in a die. A tube is placed in a first position within a die, and the mold crimps the tube to form the desired indentation in the tube. The mold is then released, and the tube is moved relative to the mold to a second position. The mold again crimps the tube to form an additional indentation. Alternately, the mold includes a roller that forms a groove on the tube. The tube is translated or both translated and rotated relative to the mold to form the groove.

The present invention provides a cable connector cover having an access door hingedly mounted to a base. The base enables alignment and connection to a computer adjacent to a PCMCIA port. A top mounting plate overlaps a portion of the computer frame to secure the cable connector cover in place. When the access door is in the open position, a cable can be inserted therein to establish a connection at such PCMCIA port. The access door can then be closed to hold the connector in place. A cable clamp also provides stress relief for the computer cable.

An EGR valve apparatus regulates the amount of exhaust gas recirculated in an EGR system. The EGR valves are opened or closed by a rotatable shaft which is actuated by a motor. Alternatively, the valves can be balanced on the shaft, the valves moving in opposing direction during rotation. An inline poppet can be employed to overcome pressure in the system prior to movement of the valves. In another alternative embodiment, the motor rotates threaded shaft to move a pintle towards and away from an orifice.

An exhaust gas recirculation (EGR) cooling system includes a valve and a cooler. A motor opens the valve allowing hot fluid exhaust gas to flow into the valve. Cooling fluid continuously flows in and circulated around the valve, reducing the amount of heat transfer from the hot fluid to the valve components. The hot fluid travels through a plurality of tubes in the cooler, continuing to transfer heat to the cooling fluid. As the hot fluid is cooled, the unburned gas in the hot fluid is recycled to be burned by the engine.
