Corrugated tube heat exchangers (CTHE) gives high heat transfer coefficient compared to shell & tube heat exchangers because of increased turbulence in tubes. This reduces heat transfer area for same process duty by almost 40 to 50% which in turn reduces overall capital investment. Hence use of Corrugated Tube Heat Exchanger is most economical solution for any process applications like condensation of vapours, cooling or heating. Corrugated tube is produced by indenting a plain tube with a spiral pattern. No tube wall thinning takes place & no strength is lost.
Corrugated tube heat exchangers have many benefits and advantages over comparable smooth tube versions:
