FIELD: heating. ^ SUBSTANCE: invention is referred to thermal engineering and may be used in district heating systems for heating service water. Heat exchanger contains primary circuit channel located between inlet and outlet connections, secondary circuit channel located between supply pipeline assembly and return pipeline assembly, heat-conducting device between primary circuit channel and secondary circuit channel, and temperature sensor. Temperature sensor is located between secondary circuit channels close to connection with return pipeline. Besides, temperature sensor contacts with heat-conducting device or situates at small distance from it. ^ EFFECT: space saving in heat exchanger when temperature is measured and good results are achieved. ^ 7 cl, 5 dwg |
