ABSTRACT:
A heat exchanger for a refrigerating appliance includes a plate, a conduit tubing, which is placed in thermo-conductive contact with the plate and is provided for transporting a coolant, and a holding material layer that adheres to the plate and to the conduit tubing. The holding material layer is made of a bitumen composition. The heat exchanger can be produced by stacking the plate, the conduit tubing, and a sheet made of the bitumen composition, whereby the holding material layer is formed form the sheet by heating and pressing the stack.
