Heat exchange unit

The utility model discloses a heat exchange unit which comprises a water collector, a water inlet pipe and a water outlet pipe, a heat exchanger; the dead steam recovery device is respectively connected with the water collector and the heat exchanger; the water segregator is connected with the heat exchanger; wherein water in the water collector is sequentially heated by the dead steam recovery device and subjected to heat exchange by the heat exchanger, and then flows to a user side through the water distributor. According to the heat exchange unit, heat of flash steam in the dead steam recovery device can be fully utilized as a heat supply source, energy waste is avoided, and heat supply cost is reduced to a certain extent. 本实用新型公开了一种换热机组，包括：集水器；热交换机；乏汽回收装置，分别与集水器和热交换机连接；分水器，与热交换机连接；其中，集水器中的水依次经过乏汽回收装置加热和热交换机交换热量后经分水器流向用户端。本实用新型提供的换热机组可以充分利用乏汽回收装置内闪蒸汽的热量作为供热热源，从热避免能源浪费，且一定程度上降低了供热成本。
