<p>A heat exchanger having a conducting wall delimiting flow spaces for the substances in heat-exchange relationship, which wall is provided at both sides with wire loops soldered thereto, and in particular said spaces are delimited by coaxial tubes. These loops are, after providing solder, simultaneously soldered to the separation wall by heating said wall, and, in particular, in the coaxial construction the wire loops are wound on the outer side of the separation tube and on the outer side of the inner tube respectively, the latter tube then being inserted into the former, and the loops are soldered by heating the separating tube. Such a heat exchanger is particularly suitable for use in a gas drier operating with a cooling medium.</p> |
