A shell pipe end socket blocking plate is fixedly connected with and blocks the port part of each cold water pipe in a sealed manner. A cold water inlet pipe connector, a cold water outlet pipe connector, a warm air inlet pipe connector and a warm air outlet pipe connector are fixedly connected to each cold water pipe or each shell pipe end socket blocking plate in a sealed manner. The heat exchanger is compact and simple in process structure, the flowing path of a pipe-communicating three-sleeve secondary heating changing cold medium channel is lengthened, the flowing speed of a cold medium is limited, the heating residence time of coldfluid is prolonged in the cavities of the cold water pipes, exchange hot water of the heat exchanger continuously flows out, and the bathing requirements of users are met.
