LOW-PRESSURE THIN-WALLED HEAT EXCHANGER AND METHOD OF MAKING SAME

摘要

A method of making a low-pressure thin-walled heat exchanger and a low-pressure thin-walled heat exchanger are described. According to the production method a thin metal cover layer and a thin cover layer consisting of metal or plastic are sealed with one another. The sealing is realized by a thin layer of a sealable polymer that is provided as coating on one side of at least one cover layer and/or by a separate intermediate layer of a sealable polymer. Both cover layers are sealed with one another by the interposed layer of the sealable polymer with the formation of a cavity suitable for the passage of a heat exchange medium which cavity can be formed as passage system. Such heat exchangers can be produced in an especially cheap way in this manner.

1. A method of making a low-pressure thin-walled heat exchanger with the following steps
providing a thin metal cover layer; providing a thin layer consisting of a sealable polymer by the application of a coating onto one side of the metal cover layer and/or in the form of a layer separate from the metal cover layer; providing a second thin cover layer consisting of metal or plastic; and sealing the two cover layers with one another by the interposed layer of the sealable polymer and forming between the cover layers a cavity suitable for the passage of a heat-exchange medium.
