Furthermore, the axes of the through holes 11 in the two rows of through holes 11 on both sides of the reversing tube 1 are not coincident, and the through holes 11 in the same row are uniformly arranged in a straight line.

Further, one or more through holes 11 are included in one group of through holes 11, and the number of through holes 11 in each group of through holes 11 is the same.

Further, the reversing pipe comprises an inlet pipe 12 and an outlet pipe 13, wherein the inlet pipe 12 and the outlet pipe 13 are respectively fixedly connected and communicated with the reversing pipe 1.

Furthermore, the reversing tube further comprises a flange 14 and a sealing plate 15, two ends of the reversing tube 1 are fixedly connected with the flange 14 respectively, and the flange 14 is fixedly connected with the sealing plate 15 through bolts and nuts.

Further, the water purifier also comprises an exhaust pipe 16, a first sealing cover 17, a drain pipe 18 and a second sealing cover 19, wherein the number of the reversing pipes 1 is two, the two reversing pipes 1 are arranged up and down, the lower part of the reversing pipe 1 above is fixedly connected and communicated with the exhaust pipe 16, the first sealing cover 17 is detachably connected with the exhaust pipe 16, the lower part of the reversing pipe 1 below is fixedly connected and communicated with the drain pipe 18, and the second sealing cover 19 is detachably connected with the drain pipe 18.

Further, still include clamp 4, screw rod 41 and base 42, the switching-over pipe 1 outside of clamp 4 suit below and rather than fixed connection, clamp 4 below and screw rod 41 fixed connection, screw rod 41 inserts in the base 42 and with base 42 threaded connection.

Further, the reversing tube 1, the heat exchange tube 2 and the partition plate 3 are made of stainless steel, aluminum or aluminum alloy.

Furthermore, the reversing tube 1 is a straight tube, the heat exchange tube 2 is a U-shaped tube, the outer diameter of the partition plate 3 is equal to the inner diameter of the reversing tube 1, and the axes of the partition plate 3 and the reversing tube 1 are overlapped.

Further, the adjacent two heat exchange tubes 2 are equally spaced in the direction along the axis of the reversing tube 1.

The working principle is as follows:

during processing, the partition plate 3 is fixedly welded with the interior of the reversing pipe 1, the heat exchange pipe 2 is fixedly welded with the reversing pipe 1, two ends of the reversing pipe 1 are fixedly welded with the flange 14, and the inlet pipe 12, the outlet pipe 13, the exhaust pipe 16 and the drain pipe 18 are fixedly welded with the reversing pipe 1.

In operation, as shown in fig. 2, the number of the through holes 11 in the group of through holes 11 in fig. 2 is two, and the partition plate 3 forms a plurality of reversing cavities 10 on the reversing tube 1.
