Compressor systems and heat exchangers
A compressor system includes a compressor having a discharge port; and a shell and tube heat exchanger fluidly coupled to the discharge port. The heat exchanger includes a shell and a tube bundle disposed inside the shell. The shell includes a first flat portion extending along a longitudinal axis of the shell from a first end of the shell to a second end of the shell, and a second flat portion parallel to the first flat portion and extending along the longitudinal axis between the first end and the second end. The tube bundle is positioned between the first flat portion and the second flat portion, and extends along the longitudinal axis between the first end of the shell and the second end of the shell.
1. A shell and tube heat exchanger, comprising:
a tube bundle; and
a shell, wherein the shell includes a first flat portion extending along a longitudinal axis of the shell from a first end of the shell to a second end of the shell, a second flat portion parallel to the first flat portion and extending along the longitudinal axis between the first end and the second end; and wherein the tube bundle is positioned between the first flat portion and the second flat portion, and extends along the longitudinal axis between the first end and the second end;
wherein the shell further comprises first and second hemispherical portions affixed to the first flat portion and to the second flat portion along the longitudinal axis and extending between the first and second ends of the shell; and
further comprising a heat exchanger inlet nozzle coupled to the first hemispherical portion and operative to supply a fluid for cooling by the shell and tube heat exchanger; and a heat exchanger outlet nozzle coupled to the second hemispherical portion and operative to discharge the fluid cooled by the shell and tube heat exchanger;
wherein the tube bundle is positioned between the first flat portion and second flat portion and does not extend into an open space defined in the first and second hemispherical portions.
2. The shell and tube heat exchanger of claim 1 , wherein the tube bundle has a rectangular cross-section along the longitudinal axis.
3. The shell and tube heat exchanger of claim 1 , the shell further comprising a first end plate disposed at the first end of the shell, and a second end plate disposed at the second end of the shell.
