A heat exchanger (1) is specified having a housing (2), in which a primary side (3) having a primary-side flow path (5) is arranged between an upstream connector 6) and a downstream connector (7) and a secondary side (4) having a secondary-side flow path (10) is arranged between an inflow connector (11) and an outflow connector (12), wherein the primary side (3) and the secondary side (4) are in heat-transferring connection along a heat exchanger section (15) and a first temperature sensor (16) is arranged in the region of the outflow connector (12). The desire is to improve the ability to regulate and monitor the heat exchanger (1). To this end, there is provision for at least one second temperature sensor (18-20, 24, 25) to be arranged on the heat exchanger section (15) and for both temperature sensors (16; 18-20, 24, 25) to be connected to an evaluation device (21).
A heat exchanger with a housing in which is arranged a primary side with a primary-side flow path between an upstream connector and a downstream connector and a secondary side with a secondary-side flow path between an inflow connector and an outflow connector, wherein the primary side and the secondary side stand in heat transfer connection along a heat transfer stretch with a first temperature sensor arranged in the region of the downstream connector, wherein at least one second temperature sensor is arranged at the heat transfer stretch, and both temperature sensors are connected with an evaluation device.
A method for the control of a heat exchanger having a primary-side flow path and a secondary-side flow path, with the primary side flow path and the secondary side flow path standing in heat transfer connection and with a temperature sensor arranged in the region of the secondary-side flow path, characterized in that an evaluation device by means of several temperature sensors determines a temperature course of the primary-side flow path and/or the secondary-side flow path, and in that the evaluation device, with the help of the temperature sensors determines a temperature difference between the primary-side flow path and the secondary-side flow path.
