<p>PROBLEM TO BE SOLVED: To provide a heat exchanger capable of suppressing overcooling or overheating of a secondary fluid by appropriately implementing heat exchange even if a flow volume of a primary fluid varies.SOLUTION: A heat exchanger comprises: a cooling air line 28 in which cooling air AC flows; a compressed-air branch line 27 in which compressed air A2 flows; heat exchange units 41 and 42 implementing heat exchange between the cooling air AC and the compressed air A2 and provided to be aligned in a flow direction of the cooling air AC; a flow regulating valve 43 regulating a flow volume of the compressed air A2 flowing in the second heat exchange units 42 located downstream in the flow direction of the cooling air AC out of the heat exchange units 41 and 42; temperature sensors 71 and 72 detecting a temperature of the compressed air A2; and a control unit 73 adjusting the opening of the flow regulating valve 43 in response to the temperature of the compressed air A2 detected by the temperature sensors 71 and 72.</p> |
