Method for a production of a heat exchanger for an inline measuring device

摘要

A method for a production of a heat exchanger for an inline measuring device includes the steps of: producing first opening provided for the connection of the heat exchanger to a temperature control piping system in a first sheet part serving for the production of one of the heat exchanger sheets; laying the first sheet part on a second sheet part serving likewise for the production of one of the heat exchanger sheets; producing an edge connection seam and inner connection locations by welding of the two superimposed sheet parts; introducing fluid through a first opening into a chamber remaining between the two sheets; superimposing a static pressure on the fluid in the chamber which exceeds a static pressure of a surrounding atmosphere to such a degree that an expansion of the chamber is initiated; and plastically deforming material of the thinner of the two sheet parts by expanding the chamber by means of the fluid with superimposed pressure.
