Abstract
The invention creates a new type of heat exchangers—Bent-Tube Heat Exchanger. It solves thermal expansion problem, allowing airtight connections for both sides of tube connection to tube sheets instead of a sliding connection on one side. Additionally, unlike in spiral-tube heat exchangers, the use of straight tube sections allows for uniform tube spacing and having the same length for all parallel tubes.
Claims8
An apparatus for heat exchange between two substances, comprising:
- a vessel with tube sheets on opposite sides and
- bent tubing inside such vessel;
- the tubing is welded to tube sheets on both sides and is bent in a such way, as to limit thermal stress to acceptable level.
An apparatus for heat exchange between two substances, comprising:
- two separate tube bundles and
- at least one tube bundles is connected to removable tube sheets in a such way that it can be removed without disconnecting tubing from tubesheets.
