[0051] In order to adjust the upper moving rail 4 and the lower moving rail 11, the inside of the moving seat 5 is rotatably connected with a bolt, the top of the bolt is located at the top of the moving seat 5, the bottom of the bolt is screwed with the transmission plate 2, and the up and down movement of the moving seat 5 can be controlled by adjusting the bolt. The adjustment mode of the connection part between the rear pressing plate 1 and the upper moving rail 4 is the same, and the lower moving rail 11 can directly slide up and down, so that the upper moving rail 4 and the lower moving rail 11 can be folded towards the center when needed, and the upper moving rail 4 always supports the rear pressing plate 1, so that the rear pressing plate 1 can slide on the upper moving rail 4;

[0052] In order to facilitate the adjustment of the orientation of the heat exchange plates 12, after all the heat exchange plates 12 are sleeved on the center column 13, a power device such as a power drill is connected with the control disc 8, grooves are formed around the control disc 8 to facilitate the connection of the transmission equipment, at this time the diameter of the center column 13 is smaller than the inner diameter of the perforation 20 of the heat exchange plate 12, so when the center column 13 rotates, it will transmit vibration to the multiple heat exchange plates 12, so that the multiple heat exchange plates 12 are unified in orientation under the influence of their own gravity, then the linkage assembly is used to connect and drive the center column 13 and all the heat exchange plates 12, then the blocking assembly is used to block part of the heat exchange plates 12 from the side, leaving only one heat exchange plate 12 from the direction of the transmission plate 2, the blocking assembly blocks the other heat exchange plates 12 from the side, the power device drives the control disc 8 and the center column 13 to rotate, thereby driving the heat exchange plate 12 that is not blocked to rotate, the other heat exchange plates 12 slide relative to the center column 13 and remain in place, after rotating one hundred and eighty degrees, at this time the first heat exchange plate 12 is opposite to the heat exchange plate 12 behind it in orientation, then the blocking assembly moves backward to release the next heat exchange plate 12, and the center column 13 rotates again, at this time the heat exchange plate 12 that is not blocked will rotate together, at this time the second heat exchange plate 12 will be opposite to the third heat exchange plate 12 in orientation, since the first and second heat exchange plates are rotating synchronously, the previous state will not change, in this way, after releasing and rotating the heat exchange plates 12, all adjacent heat exchange plates 12 can be opposite in orientation, it should be noted that at this time the rear pressing plate 1 should slightly press the heat exchange plates 12, and the blocking assembly should move an equal distance each time, in this way, the alignment of the heat exchange plates 12 is completely completed by machinery, greatly reducing the time consumed in the process of installing the heat exchanger, and ensuring the accuracy of installation and positioning, and reducing the problem of installation sequence error;

[0053] By filling the hydraulic valve 24 with liquid, the multiple top plates 25 are pushed outward, thereby fixing the multiple heat exchange plates 12 under the friction effect, after releasing the hydraulic pressure in the hydraulic valve 24 and the center column 13, the heat exchange plates 12 will become loose and can be easily removed;

[0054] The power assembly drives the two side pressing plates 7 to move synchronously, and the moving distance is the thickness of a heat exchange plate 12, so that only one heat exchange plate 12 can be added each time.

[0055] The servo motor 22 drives the transmission wheel 23 to rotate through the belt, the transmission wheel 23 rubs against the side pressing plate 7, the length of the heat exchange plate 12 is adjusted, the servo motor 22 can be detached after use, the servo motor 22 does not need to participate in the work of the heat exchanger, the two side pressing plates 7 are fixed with the series plate at the rear end, the two side pressing plates 7 can move synchronously, the side pressing plate 7 is removed after all the heat exchange plates 12 are adjusted;

[0056] The guide wheel 21 is arranged, the sliding process of the rear pressing plate 1 is facilitated, and the resistance generated in the moving process is reduced;

[0057] When the heat exchange plate 12 is detached or installed, the rear pressing plate 1 is moved to the deflection arm 6, the deflection arm 6 and the rear pressing plate 1 are turned over as a whole, the center column 13 is exposed, the traction equipment can be caught, and the heat exchange plate 12 can be detached or installed at will.
