The anti-seepage mechanism strengthens the sealing of the flange connection between the connecting pipe 11 and the water pipe 12, and prevents the bolts 22 and the nuts 23 from loosening on the first flange 2 and the second flange 21, thereby avoiding leakage between the connecting pipe 11 and the water pipe 12.

[0028] Furthermore, a shock absorbing mechanism is provided at the bottom of the heat exchanger body 1, and the shock absorbing mechanism includes a connecting rod 3, the connecting rod 3 is fixedly connected to the surface of the heat exchanger body 1, the lower surface of the connecting rod 3 is fixedly connected to a shock absorbing spring 33, the lower surface of the shock absorbing spring 33 is fixedly connected to a mounting plate 32, the upper surface of the mounting plate 32 is fixedly connected to a damper 31, and the telescopic end of the damper 31 is fixedly connected to the lower surface of the connecting rod 3. The shock absorbing mechanism can reduce the vibration amplitude of the heat exchanger body 1, thereby improving the safety of the use of the heat exchanger body 1 and extending the service life of the heat exchanger body 1.

[0029] Furthermore, a groove is provided on one side of the second flange 21, and the groove of the second flange 21 is annular. The sealing rubber ring 25 is fixedly connected to the groove of the second flange 21, and the clamping ring 24 is clamped and connected to the groove of the second flange 21.

[0030] Furthermore, a plurality of groups of circular holes are provided on the surface of the limiting ring 27, and the bolts 22 pass through the circular holes of the bolts 22. The limiting ring 27 is squeezed on the side of the nut 23 away from the first flange 2. The limiting ring 27 is restricted on the surface of the first flange 2 by the threaded sleeve 26.

[0034] Working principle: The nut 23 is passed through the circular holes of the first flange 2 and the second flange 21 at the same time. The nut 23 connects the first flange 2 and the second flange 21 together through the bolt 22 to realize the flange connection of the connecting pipe 11 and the water pipe 12. The retaining ring 24 will squeeze the sealing rubber ring 25 on the groove of the second flange 21 to improve the sealing of the flange connection between the connecting pipe 11 and the water pipe 12. At this time, the screw sleeve 26 is moved on the surface of the water pipe 12, and the limiting ring 27 is moved on the surface of the connecting pipe 11, so that the screw sleeve 26 and the limiting ring 27 are threadedly connected, the limiting ring 27 is squeezed on the nut 23, and the inner side of the screw sleeve 26 is squeezed on the bolt 22, thereby limiting the loosening of the bolt 22 and the nut 23 on the first flange 2 and the second flange 21, and preventing leakage at the connecting pipe 11 and the water pipe 12.
