    Description: The invention relates to a cooler of a compressor. Furthermore, the invention relates to a compressor with such a cooler and a method for producing such a cooler.
    In compressors, such as in turbo compressors, a process gas, especially air, is compressed. The process gas is subject to heating during compression. In order to compensate for the heating of the process gas, a cooler is positioned downstream of the compressor, which cools the process gas compressed in the compressor.
    Such a cooler of a compressor has pipes which are accommodated in a cooler housing, the pipes of the cooler being flowed around by the process gas compressed in the compressor and flowed through by cooling water for cooling the process gas.
    In practice it has been found that organic and / or inorganic deposits, a so-called organic fouling and / or inorganic fouling, can form in the pipes of a compressor of a compressor through which cooling water flows, which not only narrows the flow cross section of the pipes is, but also the cooling capacity of the compressor is impaired.
    Proceeding from this, the present invention seeks to provide a novel cooler of a compressor, a compressor with such a cooler and a method for producing such a cooler.
    This object is achieved by a cooler according to claim 1. According to the invention, an anti-fouling coating for protecting the inner surfaces of the tubes against organic fouling and inorganic fouling is applied to the inner surfaces of the tubes which serve to guide the cooling water.
    According to the invention it is proposed to apply an anti-fouling coating to the inner surfaces of the pipes which serve to guide the cooling water. This can counteract the formation of organic and inorganic deposits, ie the formation of so-called organic fouling and inorganic fouling. The flow cross-section of the pipes is not restricted. In addition, the cooling capacity of the compressor is not affected.
    According to an advantageous development, the anti-fouling coating, which is applied to the inner surfaces of the tubes, has a thickness between 50 μm and 250 μm. Then, if the anti-fouling coating has such a thickness, on the other hand, fouling can be effectively prevented, on the other hand, high heat transfer via the tubes and thus a high cooling capacity are still guaranteed.
    According to an advantageous development, the anti-fouling coating, which is applied to the inner surfaces of the tubes, consists of a thermosetting plastic, in particular a phenolic. An anti-fouling coating made from a thermosetting plastic, in particular from a phenoplastic, is particularly preferred since a thermosetting plastic can simply be applied to the inner surface of the pipes which serve to guide the cooling water, and also the heat transfer by means of such a thermosetting plastic Plastic is not affected.
    [0010] The compressor according to the invention is defined in claim 5. The method according to the invention for producing a cooler is defined in claim 7.
    Preferred further developments of the invention result from the dependent claims and the following description. Exemplary embodiments of the invention are explained in more detail with reference to the drawing, without being restricted thereto. It shows:
    Figure 1 is a schematic representation of a first cooler.
    2 shows a schematic illustration of a second cooler;
    Fig. 3 details for the manufacture of a cooler.
    The invention relates to a cooler of a compressor. 1 shows the construction of a cooler 10 of a compressor in a highly schematic manner. A plurality of pipes 12 are accommodated in a cooler housing 11 of the cooler 10. The tubes 12 of the cooler 10 have a process gas 13 compressed in a compressor flowing around them and cooling water 14 flowing through them to cool the process gas. FIG. 2 also shows such a compressor, with FIGS. 1 and 2 differing from one another only in the flow guidance of the process gas 13. It should be pointed out that the flow guidance of cooling water 14 and process gas 13 shown in FIGS. 1 and 2 is merely of an exemplary nature.
    For the purposes of the present invention, an anti-fouling coating is applied to inner surfaces 15 of the tubes 12, through which cooling water 14 flows and accordingly serve to guide the cooling water 14, namely to protect the inner surfaces 15 of the tubes 12 against organic fouling and inorganic fouling, accordingly to prevent organic deposits and inorganic deposits on the inner surfaces 15 of the tubes 12.
    The applied to the inner surfaces 15 of the coolant pipes 12 anti-fouling coating is preferably made of a thermosetting plastic, in particular a phenolic. Such a thermosetting plastic effectively counteracts the formation of fouling, furthermore it does not impair the cooling performance of the cooler 10.
    The anti-fouling coating, which is applied to the inner surface of the tubes 12, preferably has a thickness between 50 μm and 250 μm. Then, if the anti-fouling coating has such a thickness, on the other hand, fouling can be effectively prevented, on the other hand, high heat transfer via the tubes and thus a high cooling capacity are still guaranteed.
    The cooler 10 is preferably a cooler of an isothermal turbocompressor. A multi-stage compressor can also have a plurality of coolers according to the invention in order to cool the compressed process gas downstream of each compressor stage.
    3 illustrates details of a method for producing a cooler 10 according to the invention.
    First, a cooler housing 11 is provided with tubes 12 having a target contour. No further reshaping of the tubes 12 is therefore necessary.
    The inner surfaces 15 of the cooling water-carrying pipes 12 are then coated with an anti-fouling coating.
    The coating is preferably carried out with a thermosetting material, in particular with a phenoplast, in such a way that a phenolic resin is applied to the inner surfaces 15 of the tubes 12 and is then cured.
    The application of the material of the anti-fouling coating is preferably carried out according to FIG. 3 such that a tube 16 is inserted into the respective tube 12, which is to be coated on its inner surface 15, with that end of the tube 16, which is inserted into the respective tube 12, a spray nozzle 17 is formed. The coating material can be sprayed onto the inner surface 15 of the respective tube 12 via this spray nozzle 17.
    The respective hose 16 is inserted with its end having the spray nozzle 17 at one end of the respective tube 12 to the opposite end of the respective tube 12 in the respective tube 12. To spray the anti-fouling coating, the respective hose 16 is pulled out of the respective tube 12 in the direction of the arrow 18, the hose 16 with the spray nozzle 17 being moved along the entire extent of the inner surface 15 of the respective tube 12, so that then the entire inner surface 17 of the tube 12 is sprayed with the coating material.
    The spraying of the anti-fouling coating and the subsequent curing of the coating takes place at room temperature.
    The speed of pulling the tubes 16 out of the tubes 12 and the amount of the coating material sprayed over the spray nozzles 17 are selected such that the anti-fouling coating that forms has a thickness between 50 μm and 250 μm.
    With the invention, compressors coolers can be effectively protected from fouling. The invention is preferably used in turbocompressors which are used to compress a process gas such as air or the like.
