Inner container structure of heat exchanger

The utility model relates to the technical field of heat exchangers, and discloses a heat exchanger inner container structure which comprises an exchange pipe, the two ends of the exchange pipe are fixedly connected with the middles of two sets of flange plates respectively, and a plurality of sets of installation holes longitudinally penetrating through the flange plates are evenly formed in the tops of the flange plates. The bottom of the left side of the exchange pipe communicates with the end, facing the exchange pipe, of the cold medium input pipe. According to the inner container structure of the heat exchanger, the temperature storage blocks are arranged in the temperature storage pipes, and the communicating grooves in the surfaces of the communicating pipes are matched with the temperature storage blocks, so that the temperature storage blocks in the temperature storage pipes easily store temperature, and the temperature storage pipes are kept at a certain temperature; the medium with a certain tempe
