    2. The device according to claim 1, characterized in that the caps have a greater wall thickness than the cooling pipe.
    3. The device according to claim 1, -o t is based on the fact that on the one hand it is provided with a support sheet on which the cooling tubes are fixed.
    4. Device on PP. 1 and 3, characterized in that the cooling tubes are fixed on the support sheet by means of anchor elements located between the tubes.
    5. Device on PP. 1 and 4, differing in that the anchoring elements are provided in the form of hooks for hanging the cooling tubes with caps.
    The invention relates to heat exchangers for industrial furnaces, in particular to heat exchangers for cooling walls and / or dryers of industrial furnaces.
    A heat exchanging device is known that can be used to cool walls and / or clamps of industrial furnaces, which contains a series of cooling pipes installed in one plane in parallel, whose rings are. In series, the connection is made by means of caps and connected in the plane of contact by a flange, with the ends of the pipes at the points of connection-. nor made with the same diameter as the pipe lj. .
    A disadvantage of the known heat exchanger is that due to the equal diameter of the pipes at the joints, exposure to different temperatures leads to premature wear, as a result of which the service life of the device decreases. In addition, as a result of the effect of different thermal expansion on the flange connection, loosening of the screws may occur, which leads to device leakage.
    The aim of the invention is to increase the service life of the heat exchange device.
    This goal is achieved by the fact that in a heat exchanger device for cooling walls and / or covers of industrial furnaces, containing a series of cooling tubes installed in one plane in parallel, the ends of which are connected in series between themselves
    by means of caps, the ends of the pipes at the joints are made extended towards each other and are joined at the interface by welding.
    At the same time caps have a greater wall thickness than rhlazhuyuschie. Pipes. On one side, the heat exchanging device is provided with a support sheet on which cooling tubes are fixed. The latter are fixed on the support sheet by means of anchor elements located between the pipes.
    In addition, the anchor elements are made in the form of hooks for hanging the cooling tubes with caps.
    Figure 1 shows the proposed heat exchange device; in Fig.2 a section aa in Fig.1; on fig.Z - section BB in figure 1; figure 4 is a heat exchange device with a support sheet of a general view; on fig.Z - section bb In figure 4.
    The device comprises a series of cooling tubes 1 installed in one plane in parallel, the ends of which are successively interconnected by means of caps 2, the ends of the tubes in connection points 3 with caps 2 being extended towards one another and connected in the plane of contact by welding. In addition, the cooling tubes 1 are welded together in the zone of their extended portion, the Caps 2 may have a greater thickness d than the cooling tubes.
    The device (FIGS. 4 and 5) on one side is provided with an optional sheet 4,, on. wherein the cooling tubes 1 is reinforced
    Lena by means of anchor elements 5, located between the pipes and made in the form of hooks for the suspension of the cooling pipes 1 with caps 2.
    The proposed execution of the cooling device provides a significant increase in its service life due to the greater reliability of the design and its stability, since the presence of extended sections at the ends of the cooling pipes makes it possible
    make kodpak walls thicker than cooling pipes. In addition, the elimination of jumpers provides rigidity because there are no additional welds that are sources of thermal stresses.
    Supplying the device with a support sheet with anchor elements allows its use as a self-supporting unit.
