Multi-heat-source displacement heat exchanger

The utility model relates to the field of heat exchangers, in particular to a multi-heat-source displacement heat exchanger which comprises a tank body, a fixing mechanism and a heating mechanism, the top of the tank body is provided with the fixing mechanism used for independently disassembling and taking out a heat source assembly, and the upper side of the fixing mechanism is provided with the heating mechanism used for rotating the heat source assembly. When liquid is subjected to heat exchange, the liquid enters the tank body through the water inlet, the motor is controlled to operate to drive the gear to rotate, the gear blocks arranged on the outer wall are meshed to drive the fluted disc to rotate, the fluted disc rotates to drive the electric heater connected with the lower end to rotate, and the heating rod can be independently cleaned after being taken out of the tank body in an inclined state. After cleaning, the heating rod is inserted into the tank body, the sealing gasket is clamped into the to
