[0030] The limiting mechanism also includes a hand-held sleeve 403 fixedly connected to the outer wall of the baffle 402, a through hole opened on the outer wall of the baffle 402, and a push-pull rod 406 movably arranged inside the hand-held sleeve 403 for fixing the baffle 402, wherein the length of the push-pull rod 406 is greater than the length of the hand-held sleeve 403, and one end of the push-pull rod 406 can extend to the other side of the baffle 402 through the through hole.

[0031] The limiting mechanism also includes a connecting spring 404 fixedly connected to the inner wall of the hand-held sleeve 403, a movable ring 405 fixedly connected to the end surface of the connecting spring 404, and an annular magnet 407 embedded in the hand-held sleeve 403;

[0032] The outer wall of the push-pull rod 406 is fixedly connected to the inner diameter of the annular magnet 407 , wherein the movable ring 405 is made of ferromagnetic material, and the movable ring 405 slides inside the handheld sleeve 403 .

[0033] The limiting mechanism also includes a first locking groove 408 opened on the end face of the slot aluminum body 1, a second locking groove 409 opened on the outer wall of the second side plate 3, and a permanent magnet 4010 fixedly connected to the end face of the slot aluminum body 1, wherein the inner diameter dimensions of the first locking groove 408 and the second locking groove 409 are equal, and the inner diameter dimension of the first locking groove 408 is equal to the outer diameter dimension of the push-pull rod 406.

[0036] The baffle plate 402 of the two limiting mechanisms at one end of the movable slot aluminum body 1 is used to block the openings of the first side plate 2 and the second side plate 3. The specific operation is to pull the push-pull rod 406 to make it disengage from the first locking groove 408. At this time, the push-pull rod 406 will drive the movable ring 405 and compress the connecting spring 404 until the movable ring 405 is attracted to the annular magnet 407, thereby fixing one end of the push-pull rod 406 inside the hand-held sleeve 403.

[0042] The fixing mechanism also includes a positioning hole 504 opened on the end face of the T-bar 501, and a positioning rod 505 fixedly connected to the outer wall of the first side plate 2, wherein the outer diameter of the positioning rod 505 is equal to the inner diameter of the positioning hole 504, and the position of the engaging groove is kept constant through the cooperation between the positioning rod 505 and the positioning hole 504.

[0043] When the mounting portion 602 is positioned, pull the push-pull rod 406 of the limiting mechanism at the other end of the slot aluminum body 1 to disengage it from the first locking slot 408, and rotate the baffle 402 until the baffle 402 fits with the permanent magnet 4010. At this time, the baffle 402 will be attracted by the permanent magnet 4010 to fix the baffle 402. Then, insert the T-bar 501 into the horizontal slot, and make the positioning rod 505 pass through the positioning hole 504 until the T-bar 501 cannot be pushed. At this time, the reset spring 502 is in a compressed state, and the engaging slot is opposite to the through hole.

At this time, the relative side walls of the first side plate 2 and the second side plate 3 are in contact with the two outer side walls of the mounting portion 602, thereby limiting the displacement of the heat exchanger body 601 in the lateral direction. The arrangement of the T-bar 501, the horizontal groove and the through hole 603 can limit the displacement of the heat exchanger body 601 in the longitudinal direction, thereby improving the overall connection stability between the groove aluminum body 1 and the heat exchanger body 601.
