[0054] As shown in Figures 1-7As shown, by butting the butt joint ring 10 with the flange on the heat exchanger pipe, after adjusting the pull rod 17 to the appropriate position, the temporary fixation is realized by screwing the limiting head 18 and generating extrusion with the pull plate 15, and after the adjustment is completed, the adjustment of the position of the pull plate 15 is completed by sliding the sliding piece 20 in the sliding groove 14, and after the adjustment is completed, the butt joint ring 10 is close to the flange, and in the process, the pull rod 17 is inserted and passes through the hole on the flange (the pull rod 17 overlaps with the end face of the pull head 19), and after the insertion, the pull head 19 is rotated, and the pull preparation work is completed, the screw rod 11 is rotated by rotating the rotating handle, the sliding block 12 and the movable ring 13 are driven to move away from the butt joint ring 10, so that the pull structure pulls the flange and the movable ring 13, and at the same time, the butt joint ring 10 is pressed against the flange. Water is injected into the heating cavity 502 and the test cavity 501, wherein the water temperature injected into the test cavity 501 is fixed, and the water temperature in the heating cavity 502 is increased to a fixed value by controlling the heater 6 to work, and then the two water pumps 4 are controlled to work, so that the heat flow in the heating cavity 502 is input into the graphite heat exchanger 3 through the hot side input pipe 303, and after the heat exchange in the graphite heat exchanger 3, it is discharged from the hot side output pipe 304 and flows back to the heating cavity 502, and the heater 6 continuously works to keep the water temperature in the heating cavity 502 stable, and the other water pump 4 works to pump water from the test cavity 501 and into the graphite heat exchanger 3 from the cold side input pipe 301, and after the heat exchange (absorbing heat), it is discharged from the cold side output pipe 302 to the test cavity 501, so that the water temperature in the test cavity 501 gradually rises; the timer is arranged in the tester 1, and the heat exchange effect of the graphite heat exchanger 3 can be judged by judging the water temperature in the test cavity 501 in a period of time.
