ABSTRACT:
A shell and tube heat exchanger has two shell coolant and two tube coolant passageways communicating with a cavity in a shell. Removably received in the shell cavity is a tube bundle with tube headers. A locating screw extends through the shell to engage a locating recess in one tube header. The screw locates the tube bundle angularly about the central axis and longitudinally along the central axis, and is also used to electrically ground the tube bundle. An end cover, a flow separator, and resilient disc to take up thermal expansion are installed in each end of the shell to direct coolant through the tube bundle in multiple passes. Receivers with rotatable connectors are bonded to each shell coolant and tube coolant passageway. Angled connector nozzles can be connected to external conduits in any orientation.
