Abstract
A heat-exchanger with a bundle of parallelly extending pipes adapted to be acted upon by air which are hermetically closed and constructed in the manner of heat-pipes. A heat-exchanger head which is adapted to be traversed by a heat carrier medium extends transversely to the pipe bundle. The heat carrier channels formed therein are sealed off from a flow point of view against the heat-pipe hollow spaces but are in good heat-transferring connection therewith. The heat-exchanger is formed by two types of heat-exchanger plates of which the first type extends over the air stream and the heat-exchanger head and of which the second type of heat-exchanger plates is limited to the heat-exchanger head and extends transversely to the first type of heat-exchanger plates and is brazed thereto over a large surface. The heat-exchanger plates can be constructed as extrusion profiles or as two-layer partial composite laminated bodies; extrusion profiles may also be used for the cross connection of the individual heat-exchanger plates of the same type, which are grooved transversely and are brazed to the end faces of the heat-exchanger plates. However with partial composite laminated bodies, connecting pipes extending transversely to the heat-exchanger plates are preferable.
