Abstract
A process for making modular element for heat exchangers with thermoplastic tubes consisting of a plurality of tubes connected to one another by spacers located at intervals allowing the mutual tape-like positioning of the tubes. Also a process for making a tube nest consisting of a plurality of such modular elements.
Claims10
A process for making a tubular assembly which forms modular elements for tube nests comprising the steps of:
- a. providing a supply of flexible thermoplastic tubes in parallel alignment;
- b. pulling the thermoplastic tubes from the supply;
- c. spacing the thermoplastic tubes a uniform distance from one another;
- d. providing in guide means a supply of upper half element spacers to one side of the thermoplastic tubes and a supply of lower half element spacers in guide means to the other side of the thermoplastic tubes, said spacers having seating grooves;
- e. mating the upper and lower half element spacers so as to capture and space the thermoplastic tubes in the seating grooves;
- and
- f. winding the tubing assembly of thermoplastic tubes with spacers in a roll.

A process for making a tube nest from modular elements comprising the steps of:
- a. providing modular elements formed of a plurality of parallel, flexible thermoplastic tubes spaced a uniform distance from one another by spacers, said modular elements being wound on at least one roll;
- b. unwinding from at least one roll a first modular element;
- c. unwinding from at least one roll a second modular element;
- and
- d. aligning the second modular element above the first modular element such that spacers of the first modular element abut against spacers of the second modular element.
