A heat exchanger is provided with: an air coolant line (28) through which air coolant (AC) passes; a compressed air branching line (27) through which compressed air (A2) passes; a plurality of heat exchangers (41 and 42) for providing heat exchange between the air coolant (AC) and the compressed air (A2), the heat exchangers being disposed side by side in a flow direction of the air coolant (AC); a flow rate-adjusting valve (43) for adjusting the flow rate of the compressed air (A2) flowing through the second heat exchanger (42) of the plurality of heat exchangers (41 and 42), the second heat exchanger being positioned at a downstream side in the flow direction of the air coolant (AC); temperature sensors (71 and 72) for detecting the temperature of the compressed air (A2); and a control unit (73) configured to control the degree of opening of the flow rate-adjusting valve (43) in accordance with the compressed air (A2) temperatures detected by the temperature sensors (71 and 72). |
