The invention relates to a heat exchanger that can cool or heat small amounts of fluid, in particular coffee, with reasonable technical requirements. Said heat exchanger comprises a first flow path of a disconnectable coolant circuit of a refrigerator unit and a second flow path for the liquid which is to be thermally treated, in addition to an electric heater that can be connected. The heat exchanger can have a cross-flow, a counter-current or a parallel flow. |
