The regular hexagon is convenient for the rotation of the wrench. By screwing the operating block 35 with the wrench, the transfer tube 27 can be screwed quickly.

[0030] Working principle: When assembling the heat exchanger group, each heat exchanger body 8 is placed on the introduction block 5, and then the heat exchanger body 8 is pressed to make the clamping block 9 enter the clamping groove 7. Through the elastic tensile force of the spring 6, the clamping groove 7 firmly clamps the clamping block 9 to the column. By rotating the handle 22, the threaded hole 20 is threadedly connected to the screw rod 21, and under the action of the two second limiting rods 24, the U-shaped clip 23 is pressed against the upper end of the heat exchanger body 8. The remaining heat exchanger bodies 8 are installed in turn; through the two transfer tubes 27, they are respectively connected to the cold liquid outlet pipe The pipe 12 is threadedly connected to the cold liquid inlet pipe 11, and the distance is adjusted by screwing the adapter pipe 27 so that the flange 28 on the adapter pipe 27 is docked with the flange 28 on the connecting pipe 26, and then fixedly connected by the bolt assembly 29. Then the two covering blocks 34 are respectively connected to the corresponding cold liquid outlet pipe 12 and cold liquid inlet pipe 11. The connection device is connected to the cold liquid outlet pipe 12 and the cold liquid inlet pipe 11. Then, the connection device is connected to the hot liquid inlet pipe 13 and the hot liquid outlet pipe 14 in turn, and the installation is completed.

[0031] If one of the heat exchanger bodies 8 fails and needs to be replaced, first disassemble the connecting device, first unscrew the covering block 34 corresponding to the cold liquid inlet pipe 11, then unscrew the covering block 34 corresponding to the cold liquid outlet pipe 12, then remove the bolt assemblies 29 on the two flanges 28, and finally unscrew the two transfer pipes 27 from the cold liquid inlet pipe 11 and the cold liquid outlet pipe 12 respectively. At this time, the connecting devices on the cold liquid inlet pipe 11 and the cold liquid outlet pipe 12 are disassembled. Then, the hot liquid inlet pipe 13 is unscrewed in the same way. and the connecting device on the hot liquid outlet pipe 14; by screwing the rotary cap 18 on the right, it is threadedly connected to the middle seat 2 through the first limit rod 17, so that the push-out block 19 pushes away the extrusion block 4 on the left, and then by screwing the rotary cap 18 on the left, it is threadedly connected to the middle seat 2 through the first limit rod 17, so that the push-out block 19 pushes away the extrusion block 4 on the right, so that the blocking block 9 is disengaged from the slot 7, and then the heat exchanger body 8 is pulled up and removed for maintenance, and then the pipes on both sides after removal are connected through the connecting device so that it does not affect the operation of this heat exchanger group.

[0032] In summary, the heat exchanger group is more flexible and more convenient to disassemble and maintain by connecting multiple heat exchanger bodies 8 in series. If one of the heat exchanger bodies 8 fails, it can be replaced and the pipes on both sides after removal can be connected through the connecting device. This will not affect the use of the heat exchanger group, and the heat exchange work can continue, thereby improving work efficiency.

[0033] When the heat exchanger group is working, the cold liquid inlet pipe 11 on the left heat exchanger body 8 and the cold liquid outlet pipe 12 on the right heat exchanger body 8 are connected to the cold fluid device, and the hot liquid inlet pipe 13 on the left heat exchanger body 8 and the hot liquid outlet pipe 14 on the right heat exchanger body 8 are connected to the hot fluid device. The heat exchange effect is achieved by connecting multiple heat exchanger bodies 8 in series.
