[0023] When the push block 7 moves forward, it will exert pressure on the four card blocks 8, and then the four card blocks 8 are pushed to the outside of the sliding block 6 by the guidance of the slider 10, and at the same time, the spring 19 is stretched between the four card blocks 8, so that the four card blocks 8 are stuck in the inside of the card slot 11, and then the sliding plate 17 is fixed, so as to achieve the installation effect, and then the handle 4 is rotated in the opposite direction, so that the push block 7 moves backward in the sliding block 6, so that the push block 7 is separated from the card block 8, and then the spring 19 rebounds, and then the card block 8 is pulled back to the inside of the sliding block 6 by the guidance of the slider 10, and then the pushing ring 3 is pulled, so that the sliding block 6 is pulled out of the card slot 11, and then the sliding plate 17 can be pulled, so as to open the outer shell 1 for processing the inside, so as to achieve the effect of easy to use, convenient and quick disassembly and assembly.

[0024] Reference Figure 1 and Figure 3The outer wall of the push block 7 is slidably connected to the inner wall of the sliding block 6, the outer wall of the card block 8 is slidably connected to the inner wall of the sliding block 6, and the outer wall of the frame 2 is provided with a protective plate 12. The interior of the sliding plate 17 is slidably connected to a sealing plate 13, and the interior of the sealing plate 13 is provided with a pushing component, and the pushing component includes a telescopic rod 15, and the outer wall of the telescopic rod 15 is provided with a spring 2 14, one end of the telescopic rod 15 is fixedly connected to the interior of the sealing plate 13, and the other end of the telescopic rod 15 is fixedly connected to the interior of the sliding plate 17, one end of the spring 2 14 is fixedly connected to the interior of the sliding plate 17, and the other end of the spring 2 14 is fixedly connected to the interior of the sealing plate 13, the outer wall of the sealing plate 13 is slidably connected to the outer wall of the frame 2, and a rubber plate 16 is provided on the right side of the inner wall of the sliding plate 17.

[0025] Specifically, first, the sliding plate 17 is pulled back. During the pulling back process, due to the inclined shape of one side of the sealing plate 13, the sealing plate 13 can slide on the outer wall of the outer shell 1, so that the sealing plate 13 slides to the inside of the sliding plate 17 and then fits with the outer shell 1. At the same time, pressure is applied to the spring 2 14 and the telescopic rod 15 to shrink them. Then, the spring 2 14 is guided by the shrinkage of the telescopic rod 15, so that the thrust generated by the contraction of the spring 2 14 pushes the sealing plate 13 to fit tightly with the outer shell 1. Finally, the rubber plate 16 cooperates with the outer shell 1 to prevent water from overflowing.

[0026] Working principle: When it is necessary to use a heat exchanger with a quick disassembly structure, first rotate the threaded rod 5 through the handle 4 to make the threaded rod 5 rotate inside the sliding block 6, thereby driving the push block 7 to move backward inside the sliding block 6, so that the push block 7 is separated from the block 8, and then the spring 9 rebounds, and then cooperates with the guidance of the slider 10 to pull the block 8 back into the sliding block 6, and then pull the push ring 3 to pull the sliding block 6 out of the slot 11, and then the sliding plate 17 can be pulled to open the outer shell 1 to process the interior. During installation, it is only necessary to pull back the sliding plate 17, and then press the sliding block 6 back into the slot 11 through the pushing ring 3, and then rotate the handle 4 in the opposite direction to make the threaded rod 5 push the pushing block 7 forward, so as to push the card block 8 into the slot 11, and then install it. During installation, the sealing plate 13 is fitted with the outer shell 1 by pulling back the sliding plate 17, and then the spring 14 is guided by the telescopic rod 15 so that the spring 14 pushes the sealing plate 13 to fit with the outer shell 1, and finally cooperates with the rubber plate 16 to prevent water from flowing out of the outer shell 1.
