Abstract

A heat-exchanger with a bundle of parallelly extending metallic pipes arranged at least in one row which are hermetically closed off and constructed in the manner of heat pipes, and with at least one metallic heat-exchanger head extending transversely to the pipe bundle which is sealed off from a flow point of view with respect to the pipe hollow spaces of the pipe bundle but is in heat-transferring connection therewith; the heat-exchanger head is thereby formed of at least one three-layered flat partial composite laminated body per pipe row which includes two separate channels or channel networks, and which is directed parallel to the associated pipe row; one of the channels of a partial composite laminated body is thereby connected with the heat pipe hollow spaces of the pipe row to form a heat pipe channel while the other channel is adapted to be acted upon by the heat carrier medium and forms a heat carrier channel.
