Abstract
Disclosed is a shell-and-tube heat exchanger assembly, having: a first tubesheet configured for being secured to a shell of the shell-and-tube heat exchanger assembly, the first tubesheet including: a first section and a second section; the second section configured to be secured to a first shell end of the shell; and the first section including a plurality of holes configured to support a respective plurality of aluminum tubes extending through the shell, wherein the first section is configured to limit a galvanic response of the plurality of aluminum tubes when exposed to a chiller water.
Claims20
A shell-and-tube heat exchanger assembly, comprising:
- a first tubesheet configured for being secured to a shell of the shell-and-tube heat exchanger assembly, the first tubesheet including:
- a first section and a second section;
- the second section configured to be secured to a first shell end of the shell;
- and
- the first section including a plurality of holes configured to support a respective plurality of aluminum tubes extending through the shell, wherein the first section is configured to limit a galvanic response of the plurality of aluminum tubes when exposed to a chiller water.
A method of directing fluid through a shell-and-tube heat exchanger assembly comprising:
- directing a first fluid through a plurality of tubes extending through a shell;
- and
- directing a second fluid through the shell, exterior to the plurality of aluminum tubes, without causing a corrosive reaction between the aluminum tubes and a first tubesheet of the shell-and-tube heat exchanger assembly.
