[0033] The outer wall of the core body 1 is fixedly connected to a water pipe 11, one end of the water pipe 11 is provided with a valve 12, the inner wall of the core body 1 is rotatably connected to a valve stem 13, one end of the valve stem 13 is fixedly connected to a valve ball 15, a first water channel 16 is opened at the bottom of the valve ball 15, a second water channel 17 is opened at the top of the valve ball 15, and a third water channel 18 is opened on the outer wall of the valve ball 15. The valve ball 15 is rotated to make the second water channel 17 to a horizontal state, and the valve 12 is opened to allow the descaling agent to be injected into the core body 1. The descaling agent can dissolve the scale on the inner wall of the core body 1 when it contacts the inner wall of the core body 1, thereby realizing that the device can process the scale formed on the inner wall of the core body 1, and the inner wall of the core body 1 will not be blocked by scale, thereby extending the service life of the device.

[0034] In this embodiment, the other end of the core body 1 is fixedly connected to the second flow tube 4, and the outer wall of the second flow tube 4 is fixedly connected to the second flange 5. The first flange 3 and the second flange 5 can be connected and installed with the required external pipeline.

[0035] In this embodiment, the threaded surface 7 is threadedly connected to the threaded groove 6, and a rotating plate 9 is fixedly connected to the front side of the filter screen plate 8. By rotating the rotating plate 9, the threaded surface 7 can be disengaged from the threaded groove 6, and the filter screen plate 8 can be disassembled to clean the impurities on its surface.

[0036] In this embodiment, the outer wall of the valve ball 15 is slidably connected to the inner wall of the core body 1 , and the first water channel 16 is connected to the second water channel 17 , so that the liquid can flow through the valve ball 15 through the first water channel 16 and the second water channel 17 .

[0037] In this embodiment, the third water channel 18 is communicated with the first water channel 16 , and the third water channel 18 is communicated with the second water channel 17 , so that the liquid can flow through the valve ball 15 through the third water channel 18 and the first water channel 16 .

[0039] The implementation principle of a heat exchanger tube-fin core of the present application embodiment is as follows: first, the valve block 14 drives the valve ball 15 to rotate through the valve stem 13, so that the second water channel 17 is in a horizontal state, and then the first water channel 16 is aligned with the channel 10, and the third water channel 18 rotates to the bottom of the valve ball 15, and the water pipe 11 is connected to the pipe containing the descaling agent;

[0040] Secondly, open the valve 12, so that the descaling agent is injected into the core body 1 through the water pipe 11 and the channel 10. When the core body 1 is filled, close the valve 12 on the other side of the core body 1. The descaling agent fills the core body 1, and the descaling agent contacts the inner wall of the core body 1 to dissolve the scale on the inner wall of the core body 1.

[0041] Finally, open the valve 12 on the other side of the core body 1, rotate the valve ball 15 to its original state, and the liquid injected through the first flow tube 2 will flush the scale and the descaling agent out of the core body 1 from the water pipe 11 on the other side of the core body 1. Then close the valve 12 on the other side of the core body 1, and the remaining liquid can flow into the second flow tube 4, thereby realizing the normal operation of the core body 1.

[0042] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
