MODULAR BONNET FOR VARIABLE-PASS HEAT EXCHANGER

摘要

A shell and tube type heat exchanger is provided. The heat exchanger includes an elongated body defining therein a cavity that can receive a first fluid. An array of tubes having a first face and a second face can be configured within the cavity to direct a second fluid through the cavity. A bonnet can be functionally coupled to the array of tubes, the bonnet defining an interior region in fluidic communication with the array of tubes. A plate can be functionally coupled to the array of tubes, the plate defining a space in fluidic communication with the array of tubes. The bonnet can include one or more projections extending from an interior surface and into the interior region of the bonnet. The bonnet and plate are adaptable to define a first or second multi-pass flow pattern configuration of the second fluid within the array of tubes.

1. A shell and tube heat exchanger comprising:
an elongated shell body defining therein a cavity configured to receive a first fluid; an array of tubes having first and second ends and positioned within the cavity to receive and direct a second fluid through the cavity; and a partition configuration interchangeable with respect to the array of tubes and in fluidic communication therewith to direct a flow pattern of the second fluid, wherein a first partition configuration establishes a first flow pattern and a second partition configuration establishes a second flow pattern.
