One first delivery port 24 is located at the head end of the channel groove 22 and the other first delivery port 24 is located at the tail end of the channel groove 22. This application does not do the restriction to the concrete structure of water channel 22, for example water channel 22 can be snakelike distribution in a side surface of intermediate lamella 21, and water channel 22's head and the tail both ends can be located the same limit of intermediate lamella 21, also can be diagonal setting at rectangle intermediate lamella 21. The blocking portion 23 is used to prevent the corresponding water passage groove 22 from communicating with the corresponding second water passing opening 25. This application does not do the restriction to the concrete structure of separation portion 23, for example, separation portion 23 can be for setting up the convex structure at the edge of water channel groove 22, and the terminal surface that convex structure deviates from intermediate lamella 21 one end and the terminal surface parallel and level that the lateral wall of water channel groove 22 deviates from intermediate lamella 21 one end. The second water passing opening 25 may be provided on the boss structure, or may be provided at one side of the boss structure. When the partition plate 31 covers the water passage grooves 22 on each side of the middle plate 21, the end surface of one end of the blocking portion 23 departing from the middle plate 21 and the end surface of one end of the side wall of the water passage groove 22 departing from the middle plate 21 both abut against the partition plate 31, so that a medium flowing through the second water passing opening 25 cannot enter the water passage groove 22 corresponding to the second water passing opening 25, and the blocking portion 23 prevents the water passage groove 22 corresponding to the blocking portion from being communicated with the second water passing opening 25 corresponding to the blocking portion. The partition plate 31 is provided with through holes corresponding to the second and first drain openings 25 and 24. When the end surface of the blocking portion 23 facing away from one end of the middle plate 21 abuts against the partition plate 31, the medium flowing through the second water passing opening 25 can flow into the adjacent or spaced water channel grooves 22 through the through holes of the partition plate 31. It should be noted that, in this document, the correspondence relationship between the first water passing opening 24, the second water passing opening 25, the water channel groove 22 and the blocking portion 23 refers to that they are located on the same side surface of the same middle plate 21, for example, the water channel groove 22 corresponding to one blocking portion 23 is the water channel groove 22 located on the same side surface of the same middle plate 21 as the blocking portion 23. Two second water passing ports 25 are also provided. When the two first water passing ports 24 are provided on the same side of the intermediate plate 21, the two second water passing ports 25 may be provided on the opposite side.
