DETAILED DESCRIPTION

[0034] The present invention will be described in further detail below with reference to the accompanying drawings.

[0035] Example:

[0036] Reference Figures 1-5 As shown, the present invention discloses a tube-fin air conditioning heat exchanger. The heat exchanger body 1 includes an outer frame 11, within which a plurality of copper tubes 12 are horizontally arranged. Fins 13 are sleeved over the copper tubes 12. A repair space 22 is located between any two adjacent fins 13. The vertical cross-sectional width of the repair space 22 is L2. Each repair space 22 has the same cross-sectional width.

[0037] The upper half of the outer frame 11 is symmetrically provided with two repair assemblies 2, and the two repair assemblies 2 are located above the plurality of fins 13.

[0038] Each repair assembly 2 comprises a plurality of repair blocks 21. The bottom end of each repair block 21 is provided in a pointed shape. The number of repair blocks 21 in a single repair assembly 2 is equal to the number of repair spaces 22, and the repair blocks 21 are located above the corresponding repair spaces 22. The maximum width of the vertical section of the repair block 21 is L1. The size of L1 is 0.8-0.9 times the size of L2. In this embodiment, the size of L1 is 0.9 times the size of L2.

[0039] The upper half of the outer frame 11 is symmetrically provided with a plurality of first placement grooves 111 on both sides, and the bottom of the first placement groove 111 penetrates the outer frame 11. The repair block 21 is partially located in the corresponding first placement groove 111.

[0040] The repair assembly 2 comprises a pushing assembly, which drives a plurality of repair blocks 21 to move simultaneously, so that the repair blocks 21 pass through the corresponding repair spaces 22 and straighten the bent fins 13.

[0041] The pushing assembly comprises two sliding blocks 31, and the outer frame 11 is symmetrically provided with two sliding grooves 32 on both sides. The sliding block 31 is located in the corresponding sliding groove 32, and the sliding block 31 is in sliding connection with the corresponding sliding groove 32.

[0042] A sliding rod 33 is commonly provided on the two sliding blocks 31 located on the same side of the outer frame 11, and the top of the plurality of repair blocks 21 is fixed to the bottom of the corresponding sliding rod 33. A guide rod 34 is arranged in each sliding groove 32, and the guide rod 34 penetrates the corresponding sliding block 31. The guide rod 34 is in sliding connection with the corresponding sliding block 31.

[0043] The side of the sliding rod 33 away from the outer frame 11 is symmetrically provided with two first fixing rods 4, and the end of each first fixing rod 4 away from the outer frame 11 is provided with a pushing block 41. The upper half of the outer frame 11 is symmetrically provided with two protective shells 5, and the bottom and the side close to the outer frame 11 of the protective shell 5 are open. The plurality of repair blocks 21 and the sliding rod 33 are located in the corresponding protective shell 5. The side of the protective shell 5 is symmetrically provided with two first through holes, and one end of the first through hole penetrates the protective shell 5. The first fixing rod 4 partially penetrates the corresponding first through hole.

[0044] The protective shell 5 and the corresponding sliding rod 33 are commonly provided with a positioning assembly 6, and the positioning assembly 6 comprises two screw rods 61. The two screw rods 61 are symmetrically provided on the protective shell 5, and the screw rod 61 is in threaded connection with the protective shell 5. The two ends of the sliding rod 33 are provided with threaded holes 62, and the threaded holes 62 are matched with the screw rods 61.

[0045] The implementation principle of the above embodiment is:

[0046] When several fins 13 in the middle of one side of the heat exchanger are hit by external force and bend.

[0047] The operator rotates the screw rods 61 with a hexagonal wrench, and the screw rods 61 have an inner hexagonal end. The operator rotates the two screw rods 61 at the same time to disengage the screw rods 61 from the corresponding threaded holes 62.

[0048] Then the operator holds the two pushing blocks 41 at the same time and pulls the two pushing blocks 41 at the same time, so that the two pushing blocks 41 move toward the fin 13 at the same speed.

[0049] All of the repair blocks 21 enter the corresponding repair spaces 22. It should be noted that the repair blocks 21 are not in contact with the copper tube 12, and a portion of the repair blocks 21 is located outside the fins 13.

[0050] As the repair blocks 21 move, a plurality of the repair blocks 21 reach the curved portion of the fin 13 , and the operator pulls the push block 41 downward with force.

[0051] Since the repair block 21 is pointed at the point where it first contacts the fin 13, it is convenient for the repair block 21 to quickly open the channel. As the repair block 21 moves, the bent fin 13 is gradually straightened. For the bent part, the operator can repeatedly pull the push block 41 to make the repair block 21 move repeatedly in the bent part.

[0052] When the repair is completed, the operator pushes the pushing block 41 to the initial position, and then uses a hexagonal wrench to partially screw the screw 61 into the corresponding threaded hole 62 .

[0053] The embodiments of this specific implementation method are all preferred embodiments of the present utility model, and are not intended to limit the scope of protection of the present utility model. Therefore, any equivalent changes made based on the structure, shape, and principle of the present utility model should be included in the scope of protection of the present utility model.
