Abstract

The invention relates to a heat exchanger comprising one tube, and preferably a plurality of tubes, which extend through a heat-exchange chamber starting from a tube sheet, wherein the tube sheet is made of a fiber-reinforced plastics material. The invention further relates to a method for producing a heat exchanger of this kind and to the use of a heat exchanger of this kind.

Claims

exact text as granted — not AI-modified
1 . Heat exchanger comprising one tube, and preferably a plurality of tubes, which extend through a heat-exchange chamber starting from a tube sheet, wherein the tube sheet is made of a fiber-reinforced plastics material. 
     
     
         2 . Heat exchanger according to  claim 1 , wherein the tubes extend through the heat-exchange chamber between two tube sheets positioned at opposite ends of the heat-exchange chamber, and preferably the two tube sheets are made of a fiber-reinforced plastics material. 
     
     
         3 . Heat exchanger according to  claim 2 , wherein the heat-exchange chamber is tubular and is enclosed by an axially extending shell between the two tube sheets. 
     
     
         4 . Heat exchanger according to  claim 1 , wherein the fiber reinforcement of the fiber-reinforced plastics material comprises or consists of carbon fibers and/or the fibers are present as a woven fabric in the fiber reinforcement of the fiber-reinforced plastics material. 
     
     
         5 . Heat exchanger according to  claim 1 , wherein the matrix material of the fiber-reinforced plastics material comprises phenolic resin. 
     
     
         6 . Heat exchanger according to  claim 1 , wherein the tube sheet(s) preferably comprise(s) sleeve-shaped tube receptacles for receiving the tube ends. 
     
     
         7 . Heat exchanger according to  claim 1 , wherein the tube sheet(s) is/are made of a plurality individual components, and preferably comprise perforated base plates and cover plates, on which sleeve-shaped tube receptacles are retained. 
     
     
         8 . Method for producing a heat exchanger according to  claim 1 , wherein the tubes and tube sheet are joined together and are then preferably integrally interconnected. 
     
     
         9 . A method for heating or cooling corrosive fluids, comprising using the heat exchanger of  claim 1 . 
     
     
         10 . A method for evaporating liquids, in particular corrosive liquids such as acids, for example, comprising using the heat exchanger of  claim 1 . 
     
     
         11 . Heat exchanger according to  claim 3 , wherein the fiber reinforcement of the fiber-reinforced plastics material comprises carbon fibers and/or the fibers are present as a woven fabric in the fiber reinforcement of the fiber-reinforced plastics material. 
     
     
         12 . Heat exchanger according to  claim 2 , wherein the fiber reinforcement of the fiber-reinforced plastics material comprises carbon fibers and/or the fibers are present as a woven fabric in the fiber reinforcement of the fiber-reinforced plastics material. 
     
     
         13 . Heat exchanger according to  claim 12 , wherein the matrix material of the fiber-reinforced plastics material comprises phenolic resin. 
     
     
         14 . Heat exchanger according to  claim 11 , wherein the matrix material of the fiber-reinforced plastics material comprises phenolic resin. 
     
     
         15 . Heat exchanger according to  claim 4 , wherein the matrix material of the fiber-reinforced plastics material comprises phenolic resin. 
     
     
         16 . Heat exchanger according to  claim 3 , wherein the matrix material of the fiber-reinforced plastics material comprises phenolic resin. 
     
     
         17 . Heat exchanger according to  claim 2 , wherein the matrix material of the fiber-reinforced plastics material comprises phenolic resin. 
     
     
         18 . Heat exchanger according to  claim 13 , wherein the tube sheet(s) comprise(s) sleeve-shaped tube receptacles for receiving the tube ends. 
     
     
         19 . Heat exchanger according to  claim 14 , wherein the tube sheet(s) comprise(s) sleeve-shaped tube receptacles for receiving the tube ends. 
     
     
         20 . Heat exchanger according to  claim 15 , wherein the tube sheet(s) comprise(s) sleeve-shaped tube receptacles for receiving the tube ends.
