The heat exchanger unit (1) has a heat exchanger plate (2) with several parallel sheet metal plates with channels inbetween with a first group of channels connected in parallel flow to form a primary channel connected to a primary header connection (14) and primary return connection (15) and with the second group of channels forming the secondary channel. The channels of the first group are arranged alternately with the channels of the second group. A jet pump (3) with input (19,), output (18) and suction connection (20) is disposed so that the input is connected to the primary header connection and the suction connection is connected to the primary return connection. A temperature sensor (25) is mounted on the secondary header connection (16) or on a pipe leading away from same and is connected to a regulator (24) which is connected to a final controlling element (23) linked to the control member of the pump to regulate the fluid flow into the input. |
