[0026] Specifically, a first support foot 110 is provided on one side of the first pressing plate 100, a second support foot 310 is provided on the side surface of the support column 300, and the first support foot 110 and the second support foot 310 are correspondingly arranged. A first raised block 410 is provided on the first guide post 400, and the first raised block 410 is used to limit each heat exchange plate 800. A cavity 501 is formed inside the second guide post 500, and a second raised block 510 is provided on the second guide post 500. A plurality of through holes 511 are formed on both sides of the second raised block 510, and each through hole 511 communicates with the cavity 501. The limiting mechanism includes a push block 610, a push rod 620, a mounting plate 630, a plurality of springs 640, a plurality of first magnetic members 650, and a plurality of second magnetic members 660. The push block 610 is movably located on one side of the first pressing plate 100, the push rod 620 is located inside the cavity 501, the mounting plate 630 is arranged inside the second raised block 510, a plurality of springs 640 are equidistantly arranged on two side surfaces of the mounting plate 630, and one end of each spring 640 away from the mounting plate 630 is connected to a first magnetic member 650. A stopper 651 is provided on each first magnetic member 650, and each stopper 651 movably passes through a through hole 511 and is located outside the second raised block 510. The push block 610 passes through the first pressing plate 100 and is connected to one end of the push rod 620. A plurality of second magnetic members 660 are equidistantly arranged on the push rod 620. Further, a plurality of the first magnetic members 650 and a plurality of the second magnetic members 660 are both magnets, and the plurality of first magnetic members 650 and the plurality of second magnetic members 660 repel each other with the same polarity. A limiting opening 101 is formed on the first pressing plate 100, and a part of the push block 610 passes through the limiting opening 101 and is connected to the push rod 620. The locking mechanism includes a rotating block 710, a limiting block 720, and a fixing pin 730. The rotating block 710 is rotatably arranged on the first pressing plate 100, the rotating block 710 is located on one side of the limiting opening 101, the limiting block 720 is arranged on the other side of the limiting opening 101, the rotating block 710 and the limiting block 720 are movably abutted against each other, and the fixing pin 730 is used to fix the rotating block 710. A first insertion hole is formed on the rotating block 710, a second insertion hole is formed on the limiting block 720, and a part of the fixing pin 730 passes through the second insertion hole and is inserted into the first insertion hole.

[0027] In the above embodiments, a first limiting groove is provided at one end of each heat exchange plate 800, and a second limiting groove is provided at the other end. That is to say, one end of each heat exchange plate 800 is connected to the first protruding block 410 on the first guide post 400 through the first limiting groove, that is, the first protruding block 410 is used to limit one end of each heat exchange plate 800, and the other end is connected to the second protruding block 510 on the second guide post 500 through the second limiting groove. Through the cooperation of the second protruding block 510 and the limiting mechanism, the other end of each heat exchange plate 800 is limited.

[0028] That is to say, when assembling this easily detachable and efficient plate heat exchanger, first install both the first guide post 400 and the second guide post 500 on the first pressing plate 100, and then install all the heat exchange plates 800 on the first guide post 400 and the second guide post 500. It is worth mentioning that in the initial state, several stoppers 651 do not completely pass through the through holes 511. Therefore, only need to first buckle one end of each heat exchange plate 800 into the first raised block 410, and directly place the second limiting groove on the outside of the second raised block 510 at the other end, that is, all the heat exchange plates 800 can be quickly placed and installed. After all the heat exchange plates 800 are placed, by pushing the push block 610, the push block 610 drives the push rod 620 to move, that is, all the second magnetic members 660 located on the push rod 620 are pushed from the cavity 501 into the interior of the second raised block 510. It is worth mentioning that after each second magnetic member 660 enters the interior of the second raised block 510, it is located on one side of a spring 640, that is, the spring 640 does not restrict the movement of the second magnetic member 660. Since the second magnetic member 660 and the first magnetic member 650 repel each other with the same polarity, and the repulsive force is greater than the pulling force of the spring 640 on the first magnetic member 650, all the first magnetic members 650 are pushed outwards by magnetic force, which makes each stopper 651 pass through a through hole 511 and be stuck in a second limiting groove. At this time, the spring 640 is in a stretched state. Therefore, it can directly play a good fixing role. Then rotate the rotating block 710 so that the rotating block 710 blocks on one side of the push block 610. At this time, the rotating block 710 abuts against the limiting block 720, and then by inserting the fixing pin 730, the rotating block 710 is directly fixed on the limiting block 720, that is, the push block 610 is restricted from moving in the limiting port 101. Then by installing the second pressing plate 200, the second pressing plate 200 is connected to the first guide post 400 and the second guide post 500, and cooperates with the first pressing plate 100 to press all the heat exchange plates 800 from both sides, and then fix the second pressing plate 200. Finally, install the support column 300, and the entire assembly process is completed. Similarly, when disassembling, only need to pull out the fixing pin 730, and then move the rotating block 710 away so that the rotating block 710 does not restrict the movement of the push block 610. Then the push block 610 pushes the push rod 620 in the direction away from the second raised block 510, so that several second magnetic members 660 are not inserted into the interior of the second raised block 510. At this time, due to the absence of the action of magnetic force, the spring 640 needs to return from the stretched state to the initial state. Therefore, it will automatically pull the first magnetic member 650 back, that is, drive the stopper 651 to pull back, so that the stopper 651 does not restrict the second limiting groove. Therefore, after removing the support column 300 and the second pressing plate 200, all the heat exchange plates 800 can be quickly disassembled immediately, which is simple and convenient.

[0029] In summary, the above embodiments are not restrictive embodiments of the present utility model. Any modification or equivalent deformation made by those skilled in the art based on the substantial content of the present utility model falls within the technical scope of the present utility model.
